I'm in the Teyvat running group

[Final Fission]: The core material undergoes complete fission. Within a 10-kilometer radius of the fission site, all objects suffer 16D20 + "Fission Energy x 50" damage (half in radiance, half in acid; DC34 Dexterity saving throw, successful if successful, halves the damage). This damage ignores most resistances. The terrain within a 3000-meter radius of the explosion's epicenter is permanently transformed into [Crystallized Radioactive Ruins]. This is a catastrophe capable of permanently altering the map's landscape, comparable to a full-force attack during the Demon Wars.

[Vulnerable Response]: Any violent energy shock or physical impact may prematurely trigger local fission, which is extremely dangerous.

[Fission Overload]: Any attack that deals more than 25 damage to a fission creature in a single hit will shake its unstable core, causing its "Fission Energy" to immediately increase by 1.

[Energy Calming]: Ice and Holy damage effectively slow down chain reactions and cool the core. Whenever a Fission Potion is hit by Ice or Holy damage, its "Fission Energy" decreases by 1-3 points, depending on priority.

skill:

[Multiple Attacks]: Each attack is considered as four attacks, and the final hit deals triple damage.

【Fission Claws】: Consumes 1 "Fission Energy", increases accuracy by 15, increases attack range by 20 meters, deals area-of-effect damage, inflicting an additional 6D10 + "Fission Energy x 20" slash damage, and adds "Fission Energy x 10" radiant damage. The wounds left by the claw strike will continue to radiate, and the target will receive an additional [Fission Energy] acid damage at the start of the next turn.

【Fission Breath】: Consumes 5 points of "Fission Energy". The fission creature opens its giant mouth and spews out a torrent of high-energy particles, molten crystals and powerful elemental forces, covering a linear area 200 meters long and 60 meters wide.

All creatures within the area must make a DC28 Dexterity saving throw. Failure results in 10D10 Radiant damage plus 10D10 Acid damage and the inflict Level 1 Radiation Sickness. Success halves the damage. Fission Energy increases based on the number of enemy units covered.

Legendary move:

[Blink Dash]: The Fission variant uses its internal energy to perform a short-range teleport, moving up to 60 meters and launching a [Multi-Attack] attack. Its path leaves a [Radiation Scar] before the end of the turn, dealing 4D8 erosion damage for 15 seconds.

【结晶爆裂】：指定100米内一点，从地面爆裂出放射性水晶簇。该点周围30半径内的生物需进行DC25敏捷豁免，失败则受到6D6穿刺伤害并进行一次DC28力量豁免，豁免失败被束缚15秒同时受到「裂变能量×10」点光耀伤害，成功仅仅受到伤害。

[Pain Absorption]: The fission variant emits a shrill roar, frantically absorbing the remaining elemental and radiant energy in the environment to suppress the pain within its body. Its "fission energy" directly increases to the critical value, while restoring 70% of its health, refreshing all skills, resetting legendary resistances, doubling damage speed, and entering the [Final Fission] state after three minutes.

"Strong explosive power, terrifying attack power, and it can even self-destruct, what kind of heaven-defying monster is this..." Yunxiu's scalp tingled after looking at the panel data. At this point, there was naturally nothing to hide. Yunxiu quickly organized all the information and sent it to Ningguang and Liuying, who both fell silent after reading it.

"If we turn around and leave now... can we avoid this problem?" Firefly asked cautiously, "I know it sounds strange, but still..."

“Impossible. You have no idea when it will explode, and its power is absolutely comparable to the strike of a powerful demon god, and the danger it causes is even more terrifying.” Yunxiu helplessly pointed to the [Final Fission] characteristic before saying, “The Black Rock Factory’s range is only three or four thousand meters. This range, plus the radiation disaster it causes, can completely destroy the Black Rock Factory in one blow, turning the center into ruins, and from then on, no one can enter.”

"We have no other choice now. We must kill him as soon as possible in order to ensure the safety of Liyue."

"But... this is definitely more troublesome than any monster we've encountered..."

Chapter 313 Passing on the Torch in Desperate Circumstances: The Flames of War Ignite (First Update on Saturday!)

The monster itself was actually quite strong, on par with many legendary peak-level beings encountered before. The phantom of Orobas was roughly equal to it. Orobas's phantom actually had many powerful skills, but Yunxiu's rank at the time was not high enough to identify them.

Yunxiu finally understood why the Seven Stars of Liyue, despite knowing that such a creature might exist, had never dealt with it.

Of course, it is undeniable that since this thing evolved from the Treasure Weasel, it will definitely not take the initiative to attack, or rather, it will not attack often. When it encounters a strong opponent, its first thought is to run away, so the harm it causes is indeed controllable.

Then there's the question of whether it can be found at all. It would be difficult to find this monster underground without sending out several legendary peak experts, especially since it can burrow at a speed of 120 meters per second, which is faster than the flying speed of many experts, not to mention digging underground.

Strictly speaking, there are good ways to deal with this thing, such as using ice and holy magic to forcefully suppress it, but Liyue itself doesn't have any strong ice magic users...

Gan Yu's strength is actually only average among the legendary figures, otherwise she wouldn't have spent most of her time in clerical positions. Shen He is indeed quite strong in combat, but that's relative to those of the same level. Against beings of this caliber, her spells are not very effective.

Therefore, if we really want to deal with this, only the Emperor can take action. However, the Emperor will definitely only be the last resort. If everything is handled by the Emperor, then the rule of Liyue by its people will be a joke.

As for holy spells, they are even rarer than ice spells...

Of course, the Holy tree sounds incompatible with Teyvat itself, so some people will definitely assume that very few people in Teyvat practice it. Indeed, very few people do practice it, but that's not the reason.

In any world, there will always be a distinction between light and darkness, and naturally, there will be a distinction between the sacred and the evil. Therefore, Teyvat's sacred magic is actually the power of light—so very few people practice it. After all, even when the power of light is broken down into the seven elemental powers, there are still a large number of people who cannot use the elemental powers.

It wasn't until Yunxiu developed the Elemental Barrier and a series of subsequent spells that the problem of few people being able to use elemental power was truly solved.

However, the power of the Light Realm is still something that most people cannot master. Even if you are exceptionally talented and have cultivated multiple different elements using the spell system, this is still possible. Even without the spell system, there were several characters in Teyvat who could master multiple elemental powers. In fact, if you are willing to pay the price, you can even do so with the Evil Eye.

The price is that you'll live a shorter life, but it's definitely achievable.

However, the power of the Light Dimension is insufficient. There are very few people in all of Teyvat who can master the power of the Light Dimension and the Void Dimension, and even the Daedric Lords may not be able to do so. This is why Luminous is always a guest of honor wherever she goes, and she was even encased in a statue by General Raiden.

Of course, Ying is a rare being who can perfectly master both the power of the Void Realm and the power of the Light Realm, which is something Yunxiu cannot do now. He can only barely restore the power of the Light Realm, which is already his best effort.

The good news is that he has mastered quite a few ice spells. He has already learned his self-developed [Frozen Hell], [Ice Storm], and even [Ice Wall]. As for triggering [Final Fission], he also has [Time Stop] to briefly create some space for Firefly to deal damage. If all else fails, running away and calling for backup is not a shameful thing.

"As long as we can cooperate well, there should still be a great chance..." Yunxiu calculated for a moment. She thought that her magic should be able to do it with great difficulty. Fortunately, it was Liuying who came with her this time. If it were someone else, it would probably be impossible. At least Liuying can fight freely without fear of this thing's radiation.

The combination of [Fission Aura] and [Radiation Disease] is actually quite terrifying; in fact, Yunxiu herself is currently enduring the damage head-on.

8D12附带「裂变能量×40」的光耀和强酸伤害，目前这头魔物是9点裂变能量值，也就是每一轮的基础伤害就在400点到500点，每分钟都能烧掉六七十万的护盾值。

If Yunxiu didn't have a shield, even if he were a legendary powerhouse, he would be burned to death in just over ten minutes. Yunxiu's own health and modifiers are top-notch among legendary figures, and most legendary powerhouses at this time only have about one-third of his health.

Furthermore, once your body is affected by the fission aura, you will accumulate radiation sickness, which can instantly kill you...

“Of course I believe in your magical abilities, but can this thing really be used at full power?” Firefly’s voice came through the telepathic communication link: “A violent attack might trigger its local fission... but I don’t have any ice-based combat skills, although I’ve recently learned some.”

"Which combat techniques I wrote down have you learned?"

"All."

"all?"

This is truly remarkable; it hasn't taken me very long to replicate the spells and other magical techniques from the Secret Manual of Myriad Laws...

Diluc can unleash eight strikes per second using his Steel Flame and the warrior's own combat skills. So, if I give her an acceleration spell, Firefly should theoretically be able to unleash at least eighteen strikes in an instant. After all, a legendary warrior's movements are like a tidal wave, and their normal attacks each have four strikes. Yunxiu has seen Firefly's sword; it has 4D8 blunt damage plus 4D8 fire enchantment, and also +6 strength. Add to that her armor with +4 strength and her final strength value of 48.

She also has the Luck talent from [Embers of Grammer], which grants her a minimum dice roll of 6, plus a 60% critical strike chance.

A single, casual basic attack from the Firefly can deal over 2000 base damage, with a maximum of around 3000...

It doesn't look as high as the 3852 damage that Tsukihime unleashed with a single strike, but this is a normal attack!

Furthermore, this doesn't even take into account Liu Ying's own amplification combat skills. If all of them were calculated, each attack would deal approximately 4000 to 5000 points of base damage, which, multiplied by a modifier of 1482, would amount to seven or eight million damage per attack...

"Then let's get ready! Anyway, there's almost no one around here now; all the Black Rock Factory workers have been evacuated." Yunxiu waved her hand lightly, and the legendary spell [Extreme Freeze Winter] directly covered the entire area, plunging the entire kilometer-long radius into an extremely cold and deathly silence. Even the rock walls crackled from the freezing cold!

Yunxiu specially modified the legendary ice elemental spell, shortening its original duration from 20 hours to 20 minutes and reducing its range by a factor of four. The result was that the temperature drop increased dramatically to the point that even legendary powerhouses could hardly move. They had to accept a physical immunity of up to DC32, otherwise they would suffer 6D6 frost damage per second!

"True Knowledge Technique!"

A sharp light flashed in Yunxiu's eyes, and the entire space transformed into streams of light in his vision. At least within his elemental vision, he was able to clearly see everything inside the demon.

Just as things forcibly twisted together will always have various problems, this kind of monster is naturally not so perfect either. At least in this instant, he saw at least six energy anomalies, which should be the "valve" of this monster, or at least the key points.

"Accelerate! Frost Empowerment!" Two spells were cast on Firefly, and Sam's armor was quickly covered with a layer of ice element.

Yunxiu's improved acceleration technique can be described as simple and brutal: after a basic attack, an additional basic attack is added, directly increasing Liuying's attack from fourteen strikes to more than eighteen strikes, resulting in an extra 30% damage.

The monster had been awakened by Yunxiu's magic, but the powerful legendary ice magic made it difficult for him to move. Even when he was still a treasure-stealing weasel, he hated the cold weather, and this was even more true after he evolved. However, even under these circumstances, his "fission energy" was still slowly increasing.

It opened its mouth wide and forcefully spewed out a [Fission Breath]!

The dark green elemental energy was actually a strangely molten and crystallized strong acid liquid. Powerful elemental force was injected into it, and the huge area directly impacted Yunxiu and Liuying. The two dodged in an instant, but even though they were grazed, Yunxiu's shield was knocked down by five layers. His agility was not enough to exempt him from the DC28 judgment.

Just as Yunxiu dodged, another crystal exploded beneath his feet, forcibly binding him into a crystal cage. The powerful binding force began to suppress Yunxiu's body, causing his shield to creak.

In an instant, the eighteen layers of shields shattered. Even though Yunxiu instantly cast several protective spells, the shields only managed to stay at around twenty layers.

Fortunately, he had activated automatic spell counterspell in advance, so at least some minor spells and elemental energy did not cause him greater damage.

"Attack the area under its neck first, that's the first weak point!" Yunxiu shouted, immediately casting the ninth-ring spell [Gluttonous Void]. A powerful force field erupted instantly, drawing the crystals away. Yunxiu then used a stealth step to teleport directly above the monster and unleashed a [Explosive Jet] directly at the second weak point!

【Taotie Void】As the pinnacle of the ninth-ring energy manipulation spells, it can directly absorb all objects within a 100-meter radius, including this crystal cage. The priority of a simple ninth-ring spell might not be enough, but Yunxiu cast it using a twelfth-ring spell slot.

In that instant, the Firefly, unleashing her full power, drew a zigzag trajectory in the air. Moving at high speed, the armor of the Grammer Cavalry slammed into the monster's body like a meteor. The longsword in her hand was instantly coated with a layer of elemental energy that combined ice and fire, and she unleashed a twenty-two-hit combo, slashing into the monster's weak point!

"-11052756!"

The monster's health visibly decreased slightly, but this outbreak also directly led to a 4-point increase in fission energy.

"This monster actually considers the combo as twenty-two attacks..." Yunxiu's explosive spray dealt more than seven million damage and increased his fission energy by 4 points. However, he was a legendary mage with rich combat experience. He immediately threw down two ice spikes, which brought his fission energy down to about 10 points.

This also made Yunxiu very alert. If the monster hadn't exhaled a breath attack, his energy would have reached over 15, and he would have been very close to the 20-point burst...

Using Time Stop once is already the limit. Now, I may really have to continuously suppress the abnormal movement of the fission energy itself to ensure a normal kill. At the very least, I must be extremely cautious when attacking.

It seems that using fireflies for attacks is the best option...

The attack itself does increase fission energy, but ice elemental damage reduces energy, and multiple attacks are also more likely to trigger the freezing effect.

Chapter 314 A Clever Game That Quickly Resolved a Crisis (Second Update on Saturday!)

Yunxiu quickly adjusted her tactics, constantly using various ice spells to control and force the monsters to move back and forth within a small area, while also trying to apply as many buffs as possible to Liuying.

During the process of breaking through the six energy anomaly points, with the help of Yunxiu's magic, Liuying was only hit twice. Although she did not suffer from radiation sickness because of Yunxiu's advanced restoration technique, her life value was reduced by a third.

However, she had a special ability where her attack power increased as her health decreased, so she didn't let Yunxiu heal her. Reducing her health by one-third also increased her damage by one-third. Every strike she made was a powerful attack with tens of millions of damage. After a few attacks, the monster crouched down and pretended to escape. If Yunxiu hadn't used several stone wall spells to forcibly seal off the surrounding ground, this monster, which evolved from the treasure-stealing weasel, would have escaped to who knows where.

However, once the battle actually started, Yunxiu discovered that if she could withstand the radiation and had enough ice and control spells, this monster wasn't that difficult to defeat.

The biggest problem with ice magic is that it has strong control but insufficient damage. In most cases, it can be resisted by its own resistance. If it happens to be a monster with extremely high cold resistance, then it will naturally be difficult to deal with.

就像是四环级别的冰风暴也只有2D8的钝击伤害和4D6的寒冰伤害，但三环级别的火球术就有8D6的火焰伤害，四环法术位释放就有9D6，几乎是两倍！

Don't think this is insignificant, or that ice damage is only slightly lower and that as long as the frequency is high enough, the output won't actually be much lower—that's incorrect.

For example, with the same 25 points of resistance, a fourth-circle mage who has mastered Ice Storm can only deal 24 points of maximum frost damage, which is not enough to break through the resistance. At most, casting Ice Storm will cause 2D8 blunt damage, but blunt damage is one of the easiest types of damage to be immune to.

However, even with a low expected value, Fireball 9D6 can generally deal at least 30 points of base damage. With good luck and a big roll, it can deal over 40 points. Even after deducting 25 points of resistance, there is still 5 to 15 base damage. Multiplying this by the fourth ring's modifier, it can generally deal over a thousand points of damage.

Fourth-circle monsters generally have a base health of 80-120 points. A mage who has mastered the Fireball spell can kill a monster with a few Fireballs. Even if he has ice element resistance, it is not certain if he has mastered the Ice Storm spell.

This is why ice magic is relatively rare even among those in the Evocation school; people still prefer straightforward and efficient spells like lightning or fire... after all, power is everything.

Of course, Yunxiu can be said to be proficient in all methods, which is another matter. Even among legendary mages, there are few who are as comprehensive as him.

With the combined attack of the two, the monster was quickly reduced to less than 20% of its health bar.

"Be careful, he's about to go berserk!" Seeing the Fission variant begin to roar in a frenzy, Yunxiu waved her hand, signaling Liuying to retreat first. She then cast two Greater Restoration and Healing spells on Liuying, instantly restoring her to full health.

The monster frantically absorbed the surrounding elemental energy and radiation energy, and even continuously devoured the Langxuan Crystal. Its fission energy surged rapidly, and even its health bar kept climbing. Its entire body seemed to be on the verge of exploding, leaking terrifying energy, as if it would explode at any moment!

Bang Bang Bang!

Suddenly, a colossal figure erupted from the ground. The giant beast transformed into a blur, its claws gleaming with a chilling light, and charged straight at Yunxiu!

This figure is the source of the pain. It had long discovered that this human's magic was the root cause of its constant suppression of energy and output. If it weren't for his constant control, that strange robot would never have been able to attack its core!

While in a state of pain absorption, he was confident that he could kill this fragile legendary mage with a single blow!

At least in his memory, all of these fragile mages were easy targets for him.

"The opponent is in the [Pain Absorption] state, all damage is doubled and ignores resistance."

“对方发动【多重攻击】【裂变利爪】【动作如潮】，对你造成（8D8+24）×6×2×4点基础伤害，并额外造成（6D10+400）×2×4挥砍伤害与200点光耀伤害！”

“对方造成3216+3512+200=6928点基础伤害，此次伤害触发暴击，对方造成13856点基础伤害，修正系数1482。”

"-20534592!"
