As an NPC, having a lot of skills is quite reasonable, right?

Moen stared at the word "Fusion" on the panel, his breath almost stopping.

Isn't skill fusion just creating new skills?

That is an authority that only God possesses!

Now he possesses abilities comparable to those of a god.

The roars of the monsters at the city wall grew louder and louder, bringing Moen back to his senses from his shock.

Arya said she would come back to find Moen, but Moen knew that this wave of monsters would be endless, and he couldn't wait for Arya to return.

Moreover, with just one [Low Temperature Regeneration] ability, Moen's combat power is simply insufficient.

He needs to unleash his power, the strength to forcefully tear a hole in that final battle.

Therefore, he also needs to go to the city wall to acquire more skills and to verify a skill fusion idea that he had come up with in his mind.

Moen quickly finalized his plan and crouched down to begin searching the body.

The assassin didn't have any valuable equipment, but in his hidden pocket, Moen found a black bottle engraved with dark patterns and a low-level recovery potion.

Looking at the black bottle, Moen recognized it quite well.

Deep Shadow Secret Society's exclusive "Corpse Dissolving Water," an essential item for murder and robbery.

Having just impersonated someone from the Anmi Society, he turned around and ripped off a genuine one.

Without hesitation, Moen uncorked the bottle and poured the viscous black liquid onto the assassin's corpse.

"laugh!"

With a sound of decay, the corpse's clothes, along with its flesh and bones, rapidly dissolved, turning into a pool of foul-smelling black water in the blink of an eye.

"It really works." Moen exclaimed, tilting his head back to gulp down the recovery potion.

Another once-in-a-century beast tide, another assassin—Moen had a feeling that things weren't so simple, but the urgency of the situation left him no time to think. He grabbed his dagger, pushed open the door, and went out.

Flames soared into the sky atop the city walls.

Although the situation was critical, the defense line showed no signs of collapsing.

Soldiers were constantly moving oil canisters to their designated locations, while shield guards equipped with tower shields were holding off the relentless onslaught of beasts beneath the city walls.

Clearly, Arya had already given instructions on the method that Moen had previously told her.

Upon reaching the city wall, Moen picked up a bow that had fallen to the ground, nocked an arrow, and shot one, rescuing a knight who was locked in combat with an Ironclaw Ice Ape.

[Team-up kill: Ironclaw Ice Ape Lv.8]

Experience points gained: 60 + 36 (reward for killing enemies above your level)

[Gained Mortal Fragments: 2 + 10 (First Kill Reward)]

[Unlock Statue: Ironclaw Ice Ape]

Moen arrived at the edge of the city wall, shooting arrows to support the soldiers below while observing the battle.

Below the city wall, Arya was weaving through the beasts.

Her longsword was wrapped in holy runes, and each swing brought forth a burst of bloody light. Those thick-skinned frost-spiked porcupines couldn't last more than two moves against her.

Suddenly, three enormous parasitic bears of the winter demon tree broke through the herd of beasts and charged toward the city gate, braving a hail of arrows.

The parasitic wood on their backs shimmered with green light, giving rise to a thick layer of wooden armor that covered their entire bodies; ordinary swords could only leave white marks when they struck it.

Arya raised her longsword, about to order the oil jugs to be thrown, when she caught a glimpse of a figure on the city wall.

Moen was standing at the perfect throwing point, holding a huge canister of kerosene in his hand.

With a powerful swing of his arm, he hurled the oil canister down, striking the parasitic bear at the very front with pinpoint accuracy.

Immediately following, a flaming arrow arrived, and flames instantly rose up.

Parasitic wood is extremely flammable. When ignited by kerosene, the high temperature instantly burns through the bear's defenses.

The giant bear let out a pitiful howl as its indestructible wooden armor crumbled into charcoal in the flames, revealing the flesh beneath.

"Kill!" The morale of the knights below soared, and their spears plunged fiercely into the charred gaps!

[Team Kill: Winter Oni Tree Parasite Bear Lv.10]

Experience points gained: 75 + 75 (reward for killing enemies above your level)

[Gained Mortal Fragments: 3 + 5 (First Kill Reward)]

[Unlock Statue: Winter Oni Tree Parasite Bear]

After taking down several more monsters, Moen reached level 6 and accumulated 42 Mortal Shards.

Without even looking at the results of the battle below, he turned and went into an unattended storage room in the city wall tower, locking the door behind him.

The mist dissipated in the dark corridor.

Three enormous statues were revealed: the Frostthorn Porcupine, the Ironclaw Ice Ape, and the Winter Ghost Tree Parasitic Bear.

Moen strode forward and placed his palm on the cold surface of the bear statue.

[Live Tree Beetle]

[Rank: Mortal]

[Cost: 15% of current health]

[Cooldown: 20 seconds]

[Description: You imitate the survival method of the Winter Oni Tree Parasitic Bear, using your own blood as nourishment to forcibly catalyze the plant-type magic dormant on your body surface.]

[Skill Effect]

[Symbiotic Hardening: Tree armor covers the entire body, granting a layer of bio-armor lasting 10 seconds, during which physical and magical damage reduction is increased by 30%]

[Exchange Price: 40 Mortal Fragments]

Without the slightest hesitation, Moen chose to exchange for the [Living Tree Armor].

A flash of light, and 40 fragments were deducted.

Moen felt a surge of energy enter his brain, and the method of using the [Living Tree Armor] clearly appeared in his mind.

The parasitic bear statue in front of me, like the lizard statue, has turned into jade, and its other skill, [Root Entanglement], can no longer be redeemed.

Turning his head to look at the other two lifelike statues, Moen was very envious.

At this moment, having an extra skill means having a better chance of survival, but unfortunately, Moen doesn't have enough fragments left to exchange for other skills.

He exited the corridor, took a deep breath, and opened the [Skill Fusion] panel attached to the Life Stone.

It was a page completely different from the normal skill interface. The background was a layer of dark void, with only a socket in the very center and a base for placing items on each side.

Below are his only two skills, materialized as two crystalline skill stones: [Low Temperature Regeneration] is light blue, while [Living Tree Armor] is the dark brown of the bark of the Winter Ghost Tree.

With trembling hands, Moen dragged the Life Stone [Deceitful Engraving] into the central inlay slot.

"Buzz!"

A dark ripple instantly appeared on the panel.

Please add the skill to be fused.

Moen dragged the two skill stones up one after the other.

The next second, lines of pale green text appeared at the edge of their field of vision:

[Compatibility: High]

Success rate: 82%

[Recommendation: This combination exhibits directional resonance and could be a priority for integration]

If the fusion fails, the Life Stone, as the main material, will shatter, and the skill will undergo an irreversible and malignant mutation.

"Just as I expected!" Moen's eyes turned fervent.

His approach is correct; one is responsible for healing, and the other for increasing defense. The two complement each other very well.

Take a gamble!

Moen pressed the fusion button.

The moment the three came into contact, the background of the interface changed from deep darkness to a distant starry sky.

The Life Stone emitted ripples that enveloped the two Skill Stones.

Moen felt an immense force, like a hammer falling from above, skillfully merging the three elements together, then abstracting the concepts of skills into symbols that were deeply etched into his mind.

A prompt will pop up:

【Successful integration】

[Gained Skill: Bloodstained Frost Robe]

Moen excitedly clicked on the details, and when he saw the skill effect, his eyes widened in disbelief.

[Skill: Bloodstained Frost Robe]

[Rank: Mortal - Swan Song]

[Description: Using the lies of the Life Stone, you blurred the line between life and death. You deceived the body, making it believe that death had arrived, thus freeing it from the fear of the cold and pain; you deceived the soul, turning every drop of blood that flowed into a bargaining chip to claim the life of the enemy.]

[Consumption: Instantly burns all mana (must be greater than 50%), and for 24 hours after the skill ends, all attributes are forcibly reduced by 80%]

Cooling time: 48 hour

[Skill Effect]

[Liar's Boundary: Grants a pseudo-immortal state upon activation, lasting 5 seconds. During this time, regardless of the type of damage received, your health will never fall below 1 point.]

[Frost Armor: The cold numbs you. Your magic resistance is instantly increased by 200% (magic damage reduction cap 75%), and you become immune to all freeze and slow effects.]

【Bleeding Blood: The fangs of a dying beast are the sharpest. Your next attack's damage will no longer be calculated based on your base stats, but will instead be forcibly converted to: Lost Health × 2.5】

Moen slowly closed the panel. He looked out the window at the beast tide that was almost swallowing the city walls, but a smile appeared on his lips.

"We have a chance of winning."
