The infinite sword system has been mastered, and you say this is the dragon clan?

Chapter 321 Amatras!
"Niten Ichiryu: Water Form!"

Emiya wielded the Steel Ame Murakumo and the Light Ame Murakumo, a product of Susanoo's divine power. He tried hard to control the power. The blade of the sword shone brightly under the divine power and authority, shining black and dazzling gold. "Reverse Tide!"

The blade's edge collided head-on with the surging waves at a strange angle. The destructive power, engulfed in elemental turbulence, collided briefly with the high-density water waves created by the snake god.

Suddenly, the blade deflected, and Emiya controlled Susanoo and exerted force. In less than a second, the huge wave of divine power, heavier and harder than an iceberg, was shattered! Power sang joyfully, and the water flow reversed, forming a black water blade that flew in the opposite direction!
The essence of martial arts, combined with the power of the gods, brought him unexpected surprises!
The shattered waves were cut into pieces, and then under the effect of Susanoo's two-sword style, dozens of black water blades were formed one after another, crashing into the raging waves raised by the snake god. The continuous output of destructive power disintegrated the snake god's subsequent water tide offensive, followed by a series of loud sound waves that were more shocking to the eardrums than a thunderstorm!
In just a few milliseconds, due to the shocking water battle between the two gods, the breath of the gods began to make all things in nature run wild. The black blade shattered the water tide, causing a water vapor storm of dozens of kilometers to roar wildly, which immediately destroyed the vast amount of potholes and mountains outside Edo Castle.

In the short period of time that followed, flood waves even poured down on the surrounding mountains within hundreds of kilometers. In addition, there were high-speed flying water vapor and raindrops, which were like deadly projectiles flying all over the sky, destroying large areas of beautiful mountains and forests!
Sure enough...it works!
Gundam knows martial arts, even gods can't stop him!
In fact, just now, Emiya was thinking about how to familiarize himself with the new powers brought by Fullmetal Alchemy, while studying Miyamoto Musashi Niten's "severing cause and effect" realm...

It's best to strive for both speed and quality, to grasp both ends and make both strong. At the same time, we must adhere to the Origin of the Sword as the guiding line, organically combining various martial arts represented by Ertian Yiliu, developing the God Slayer's ability panel as quickly, efficiently and economically as possible, and deeply tapping into the advantages of power to make up for the shortcomings...

Hence the attempt just now, and the result of the first attempt can be said to be quite fruitful and commendable.

Emiya secretly gave himself a thumbs up for his occasional flash of inspiration.

Maybe after he becomes proficient in using it, he can control the Susanoo Gundam, with extraordinary swordsmanship in one hand and supernatural powers in the other. The combination of the two will instantly astonish everyone and give his opponents endless surprises!
"—!"

Suddenly, the roar of the waves breaking through the waves interrupted the inspiration that flashed through Emiya's mind.

He saw his opponent - a giant snake god taller than a mountain, howling in the storm. Its dark and moist scales reflected the moonlight, and their close arrangement made the snake's body look like a dark mountain range flashing with terrifying light, shaking unnaturally among the waves. Then, those beautiful scales fell off in large pieces like waves blown away by the wind, which made people feel creepy.

Emiya narrowed his eyes and took a closer look. It turned out that the snake was "changing scales". After the shiny black scales fell off, a layer of new, sparkling azure scales quickly appeared on the snake skin. He didn't know if it was an illusion, but after the old scales quickly fell off after being soaked in water, the snake god's body was gradually growing larger.

"BB, what's the situation over there? Am I seeing correctly, she's getting bigger?"

Beside the massive lightning giant Susanoo piloted by Emiya, a purple-haired girl floated, steady on his shoulders. Her hairband whipped by the wind and rain, yet she remained unmoved. Several floating virtual screens silently emerged, quietly surrounding BB.

"Yes, that's right. I guess it's because Miss Shuten's transformation into divinity is accelerating! Presumably, the Holy Grail she devoured, a product of her father's soul, is constantly forcing her to evolve."

"How does it compare to the Ibuki-douji who appeared at the end of the Holy Grail War I experienced?"

In his mind, Emiya kept estimating the strength of the snake god evolved from Shuten.

According to the records of the Holy Grail War, the snake god Shuten-san's divine power is currently rising, but it hasn't significantly surpassed the other party. However, due to consuming the entire Holy Grail, the opponent's spiritual power has expanded dramatically, far surpassing... Hey, it's actually accelerating again! It's about to surpass the original Ibuki god!

"Tsk!... What's going on?"

Emiya could hear the surprise in BB's tone, and his mood sank. It was true that he wanted to use the Snake God to hone new martial arts and powers for his opponent, but he also didn't want to get into trouble suddenly because of some inexplicable accident.

"Why is she so much bigger than Ibuki Douji?"

"I understand!" BB exclaimed, a flood of data flashing across the virtual screen in front of her. "It's the Dragon Vein! It's based on the Dragon Vein and the Night Food Source!"

"So that's it!"

After BB's reminder, Emiya once again realized a blind spot in his thinking that he had not noticed before:

In reality, the Nibelungen "Night Food Field" had actually been in a semi-destroyed state before the arrival of Ibuki Douji because of the joint efforts of Emiya Natsumi and Norton and others outside, which had damaged the dragon vein to a considerable extent.

Therefore, Ibuki Douji did not have the opportunity to use this Nibelungen, after all, she came to the world after the Night Food Source was damaged.

In this singularity, without the involvement of external factors like Xia Mi and Norton, the Night Food Field remains intact, and the White King, or Yamata no Orochi, is the undisputed primary controller. Just like Leviathan, controlling the Zero Viaduct, he manipulates this world in various ways...

No, Leviathan wasn't even the owner of the Nibelungen on Skyway Zero; he merely borrowed the authority from Odin. And now that Shuten's evolved Serpent God had devoured the Holy Grail, he was no different from the White King's highest authority!

But having said that, what exactly is this snake god doing in front of us?

Without Emiya asking, BB quickly came up with the answer, "Amazing... She's expanding the dragon veins!"

"Wait, expansion?"

[That's right!] BB's virtual display screen revealed a map of the dragon veins beneath Tokyo in the real world.

The dragon vein was originally located in a shallow underground layer, but it is now advancing vertically at an astonishing speed into the asthenosphere, approximately 80 kilometers below the surface. It is also spreading horizontally like a net. Currently, Yamanashi and Gunma prefectures are fully covered, and it is further expanding into Nagano and Aichi prefectures, and Nagoya is about to be included...!

The so-called asthenosphere is the location where magma is generated underground, usually due to plate tectonic movements. The depth of the asthenosphere varies globally, generally being deeper on land and shallower in the ocean.

BB nervously checked each data stream, but it was obvious that the snake god's actions were beyond their expectations.

[It shouldn't have gone this smoothly, but this island nation is located in the Ring of Fire, where tectonic plate subduction causes frequent asthenosphere activity and shallow depths, some as shallow as 60 kilometers! They've already reached that depth…! —They're further accelerating the lateral expansion of the dragon veins!] Emiya quickly grasped the situation, re-assuming his stance, and as he swung his sword forward, said, "I see. Shuten-dōji wants to maximize the Holy Grail's power by expanding the dragon veins!"

According to the understanding gained through the Holy Grail War, the Holy Grail system would be connected to the local dragon veins. The higher the quality of the land and the higher the magical power content of the dragon veins, the more magical power the Holy Grail could absorb, and the greater the effect it could exert.

Of course, in this dragon world, dragon veins or earth veins are essentially super-large alchemical matrices, and the asthenosphere with active magma is an area where underground metal elements frequently move and migrate, which is indeed suitable for the expansion of earth veins, thereby easily exerting the role of the alchemical matrix to a greater extent.

From this perspective, the effectiveness of the Holy Grail has indeed been enhanced to a considerable extent.

Boom! Before he could finish his words, a raging tide of fire erupted. BB looked up and saw that the snake god opposite him had been engulfed by a huge ring of scorching fire in the blink of an eye.

This is the Fire Type of the Crimson Lotus Dance of Niten Ichiryu, which uses the divine sword Ama Murakumo as the basis for activation, and at the same time applies the destructive and killing power of Ama Murakumo of Steel. The combination of the two actually forms a black flame that seems to burn and kill living things and is difficult to extinguish!

Amatras!
Puff! The surging water evaporated in the blink of an eye. The snake god's scales burst out, but were also surrounded by the wide ring of fire and swallowed up completely in the blink of an eye. Then, the dark flames climbed up the snake god, which had grown to the size of a mountain range, like a cancer.

"——!" A sharp and piercing hissing sound penetrated the eardrum, revealing a new blue scale that seemed to have some characteristics. It looked like the new scales were replaced to resist the tide and thrive in the raging waves, but this water resistance was ineffective in front of the black divine flame.

So, the snake god had to stop expanding, and it was forced to start a new round of "scaling" - taking advantage of the fact that the black flames did not seriously burn it, it first shed the scales on its body, and then, the blue scales wrapped in black flames were all thrown away, and the new crimson scales sparkled.

The crimson scales caused high temperatures to evaporate the seawater as the snake swam. It seemed that these were new scales with fire properties and resistance.

[Wow! What a shame! I was hoping to see a barbecued snake feast!]

BB felt the heat of the air blowing in his face and whistled.

She knew that Emiya was trying to interrupt the expansion of the Snake God. Although Shuten-douji's original purpose was to "play games", who knew how many lives would be paid for this "game" in the concept of inhuman existence?
Emiya's eyes became more focused. Since you have changed the scales again, I will change to sword skills with other attributes to fight with you.

Do you think you are the only one who can switch? You are stupid, I can also switch in the same way, and I don’t make the same switch twice.

Niten Ichiryu was originally born out of the concepts of the "Gorinsho" (The Book of Five Rings). Emiya mastered all of the "Earth, Water, Fire, and Wind" elements, except for "Sky." In a sense, the snake god's scale-changing technique was simply countered by his Niten Ichiryu! Of course, the prerequisite is that Niten Ichiryu has reached the realm of the gods.

Emiya had… for who knows how many times he'd changed his stance when something suddenly struck him. He quickly asked, "Minamoto no Raikou and the others have arranged for the people to be evacuated to the shelter, right? The tides and waves are pretty strong here, but is everything okay over there?"

He and the rest of the Chaldeans hadn't yet learned what the shelters the Eight Snake Clan had prepared in the Night Food Plains looked like and what level of protection they possessed. They hoped to remain unscathed during the massive tsunami unleashed by the Serpent God.

[Hmm, let me see... Hey, senior, don't worry. Minamoto no Raikou and the Snake Eight Clan are very clever. Their shelter is actually a passage leading to the outside world of Tokyo. By this time, I'm sure most of the people have been relocated.]

"That's good."

Emiya nodded, and immediately prepared to attack again.

At this moment, he suddenly felt a shadow above his head rapidly expanding.

Mountain?
Emiya looked up and saw an entire mountain rapidly flying towards him!

...There's no sign of divine power. Is this a trick played by Takeda Shingen and his gang?

"Earth Form! Acala!"

Emiya changed his stance in an instant, and his fierce momentum suddenly subsided. He swung the blade in a tight and smooth arc, and at the same time caused Susanoo to rotate. Then, pieces of ochre - no, almost black sword energy collided with the flying mountain like a group of rocks, and in an instant, the mountain collapsed!
Then, out of the corner of his eye, Emiya caught a glimpse of the direction those heroic swordsmen were heading. They were riding flame-wrapped horses away from the side of the Serpent God. Mixed among them were a large number of Flame Cavalrymen and Takeda generals, creating a deliberate maze to confuse the viewer. In addition, the huge amount of steam rising from all around made it even more difficult to distinguish them.

So that's what it is. It's Takeda Shingen's treasure, "Wind, Forest, Fire, and Mountain". They walk on the "wind", form their own "forest" position, move with the momentum of "fire", and finally move the "mountain" to smash the enemy. The mountain is at the end, which is of course an effective way to divert attention. By the time Emiya reacts, they are already very far away.

"Hmph! Want to escape?"

There are no doors!

Emiya remembered that they still had several mass-produced divine swords in their hands. Although their strength was just so-so, they couldn't let them get away.

It was one thing for him to not care about or look down on these people, but it was another thing for them to escape on their own while they were still on the chopping block. This was unacceptable. In Emiya's eyes, they were just tools to keep the swords safe. Although they were useless, they couldn't just run away. If they did, they would be easily killed and their power taken away.

I believe that Takeda Shingen also saw this clearly, so he decided to give it a try.

"Earth Form! Vajra Tripod!" Emiya's Steel Ame Murakumo was wrapped in a dark and shiny aura of power. He raised both swords high, and the next moment he slammed them into the ground under the waves.

Rumble!
The sea suddenly surged with exaggerated waves, and endless tsunamis were set off, even revealing the shaking surface of the earth - this was because Emiya used the sword as the hub to input divine power into the ground, thus creating a strong seismic wave!

Want to run? Can you escape?
