I am Kamen Rider who reverses dimensions

Miyamoto Musashi quietly recounted her ordeal to Senji Muramasa and Li Shuwen. Senji Muramasa briefly examined the location of the spirit core with his [Eye of Karma], paused for a moment, and then looked at Genji and said:

"There's a method we can try, but if we still can't cut it off, then we might have to consider retreating."

How much preparation time is needed?

Gensou took out the dual drive, fastened it to his waist, and asked Senko Muramasa, while the swordsmith asked in a low voice:

"How long will it take you to kill this bastard again?"

“His condition has deteriorated drastically, and his magic power has not been fully replenished. Three minutes, at most three minutes. With Mr. Li Shuwen holding him back, I will definitely kill him again within three minutes.”

"Okay, you guys go ahead, we'll take care of things here."

"Sir, please help me."

"Haha, you're too kind! Come on, kid!"

Seeing Genjiro and Li Shuwen rushing towards the monster, Senji Muramasa looked at Miyamoto Musashi and said:

"Musashi, a good swordsman sometimes needs a good sword, but my sword might be a bit difficult to master..."

"Don't worry!"

Miyamoto Musashi looked at Senji Muramasa with a resolute gaze and said:

"I will absolutely, absolutely, absolutely not stop swinging my sword until I sever that spirit core!"

"Okay, I'll begin then."

Senko Muramasa took a deep breath, tore off the haori beside him, tossed it aside, and chanted softly:

"The ultimate strike I pursued in the past was not a steel blade that could shred flesh, break bones, and kill."

'Clang—!'

As the swordsmith finished speaking, the sound of steel being hammered echoed out of nowhere in this space, and at the same time, signs of spatial distortion appeared around Senji Muramasa.

"What I seek is to settle the score with resentment, to sever the ties, to sever the fate, to sever the karma of the past, that is, to be liberated from the karma of the past."

Crimson sparks began to appear around Senji Muramasa, and the scorching heat spread out along with rising steam. The figure of the legendary swordsmith gradually disappeared into the air, but the sound of forging iron grew clearer and clearer, more and more deafening, as if Senji Muramasa had begun the craft of sword making right there and now.

"To reach this point is the result of countless studies, using thousands of swords as models to build numerous sword mounds."

"Arrival here is the convergence of all things."

"To be displayed here is the wish of all things."

"Gathered here are all non-businesses—everything in my life exists to reach this blade."

"The pulse of the sword is here!"

"Take this! This is mine, Muramasa, the Muramasa!!!"

With Senji Muramasa's shout, his unique barrier instantly unfolded, creating a wilderness filled with countless swords. But then, all the swords shattered like snowflakes, leaving only a sword in Senji Muramasa's hand.

This is the ultimate sword created by Senji Muramasa using a treasure. It is a sword that can sever time, space, and causality. The sword is inscribed with "Tomokari Muramasa". It is a divine weapon that appeared from the tail of the Yamata no Orochi, the largest calamity of the island nation, which was killed by Susanoo-no-Mikoto. It was a crimson flame monster with eight heads and eight tails and a body so huge that it spanned eight valleys and mountains!

Meanwhile, on the other side, Li Shuwen, his face dark, strode along the fiery path that Yuanxiang had cleaved open with his wind blades, forcefully leaning against the strange man and knocking him back. He then followed up with another strike, "No Two Strikes," forcibly interrupting the strange man's attack and forcing him back again. He then caught Yuanxiang's Rider Kick, which came crashing down from the sky, and the black and red head was once again kicked off. The spirit core hidden in the Sea of ​​Life began to recover.

At that moment, Senji Muramasa unhesitatingly tossed the divine weapon in his hand to Miyamoto Musashi. The young swordsman roared, and his 'essence,' 'qi,' and 'spirit' reached absolute unity at this moment. Blood spurted from the corner of Miyamoto Musashi's demonic eye, and the veins on his hands that held "Muramasa Muramasa" bulged, with blood seeping from his skin.

In an instant, Miyamoto Musashi transformed into a blood-soaked figure, but she was completely unaware of it. In her eyes, everything unrelated to the Spirit Origin vanished. The wrathful Niou behind her seemed to merge with her in a daze. Without a sound, only a frost-like sword light flashed, leaving a sword mark called 'Heavenly Flower' in the Sea of ​​Life of the Mother Goddess Tiamat.

"No, damn it, damn it, Servants! You're all just wasting your time..."

Sensing the disappearance of its spirit origin, the monster let out a chilling roar, but before it could finish howling, Gengo punched the half-grown head, sending the bastard to its demise. At the same time, a purplish-black light emerged from Tiamat's Sea of ​​Life—the power of the 'Joker'. It swirled joyfully in the air before finally returning to the memory in Gengo's hand.

In an instant, a tremendous power surged into Yuanxiang's body. Although it was far from being as divine as before, it was still worthy of praise.

"Alright, let's leave now."

Senjimura handed Miyamoto Musashi, who was covered in blood and had fainted from exhaustion, to Genji, and whispered:

"It's all over here now; it would be too dangerous to stay any longer."

"Grandpa Muramasa, are you leaving?"

"what."

Senji Muramasa smiled nonchalantly, and at the same time, golden spiritual particles scattered from his body, which was the true manifestation of a Servant returning to the Throne of Heroes.

"Now I finally understand why they sent a swordsmith like me, who isn't good at fighting, here. It was all for this one strike, huh? Hahaha. But to be honest, I'm still not entirely satisfied, even though this strike was forged using my spirit core. Alright, alright, let's go, let's go. I won't fall into the black mud and become your opponent. Hurry up and go."

"Take care, sir."

"Senji Muramasa, until we meet again."

Genji was silent for a moment, then, while treating Miyamoto Musashi, he bowed slightly to Senji Muramasa to say goodbye. Li Shuwen casually clasped his hands in a fist salute and followed Genji away. Senji Muramasa smiled, and then, seemingly still pondering what went wrong with the forging just now, disappeared into the singularity.

But before Yuanxiang and Li Shuwen could return to the monster defense line, a chilling and eerie cry suddenly rang out behind them. The ear-piercing scream, "aaaa—", carrying magical power, swept in from the Persian Gulf, as if some terrifying being was using its power to sweep across the entire world, announcing its return.

However, the shriek of "aaaa——" suddenly stopped. Yuanxiang and Li Shuwen exchanged a glance and immediately sped up, returning to the monster defense line, where they saw Merlin talking with Gilgamesh.

"It seems that Mr. Muramasa has ultimately chosen self-sacrifice?"

After glancing at the state of Gensou and his group, Merlin realized something, sighed, then shook his wand to heal Miyamoto Musashi's injuries, and continued:

"It seems our worries have come true. Although the Demon God Pillar has not yet been completed, the Mother Goddess Tiamat has already taken that fake as her child. The child has been killed, and the mother will naturally be enraged. Has that goddess finally awakened from her slumber?"

"Wait, wasn't it said that the reason this singularity can continue to exist is because of my power?"

Gensou quickly interrupted Merlin, holding up the memory device in his hand and saying:

"Now that I've retrieved this power, this singularity should also be unable to..."

"Clearly, this singularity shows no signs of dissipating."

Merlin shook his head and said softly with a helpless expression:

"It now seems that the mother goddess Tiamat's own status may have become the new twist point of this singularity, or perhaps when your power was in her body, a part of it was assimilated by the mother goddess, and she continued to perform the function of the original twist point. But in any case, defeating the mother goddess is undoubtedly the way to resolve this singularity at present."

"........"

Gensho sighed, looking troubled. Then, he suddenly realized something and looked at Merlin, saying:

"Since the awakening of the mother goddess Tiamat was due to the murder of the 'child,' then wouldn't it be better to let the 'child' return? I..."

“Yuanxiang, the Mother Goddess has awakened.”

Merlin looked at the boy in front of him and said:

"Furthermore, even if you voluntarily enter the Mother Goddess's body and become her 'child,' it will only postpone her awakening, not stop it from happening. If you and the Mother Goddess attack Uruk together, aren't you overestimating our strength? That's why I didn't tell you this."

"Alright, all of you, withdraw now. Soldiers and Servants alike, return to Uruk."

At that moment, Gilgamesh's command came from the mirror, and the king, sitting on his throne, pinched his brow and said:

"If that god awakens, the monster defense line will have little value in continuing to be maintained. I have already evacuated all the civilians between the monster defense line and Uruk to Uruk City. From now on, Uruk will become the place where we fight the Mother Goddess."

"Wait a minute, doesn't the Gates of the Underworld need three more days to be ready?"

Yuanxiang heard something and hurriedly spoke up to remind him:

"Although the distance between Uruk and the monster defense line seems far, I can run back and forth in a few minutes. Will Mother Goddess Tiamat really walk this distance for three days?"

"Of course not, don't ask such stupid questions and you'll embarrass yourself."

At this moment, Ishtar, who appeared from the side, couldn't help but complain:

"What kind of being is the Mother Goddess? Three days? You could walk from the Persian Gulf to Uruk in a single day!"

"That's right, so I'm not on the list of people to be evacuated from here."

Merlin smiled and pointed to himself, then waved his wand, and a scene appeared before everyone—

That was the Persian Gulf, the place Yuanxiang and Li Shuwen had just left, but it had undergone earth-shattering changes. The Sea of ​​Life, filled with black mud, had replaced the waters of the Persian Gulf and surged to the ground. In this dark 'sea,' a woman with ram's horns stood in the center, her hands bound by ropes, quiet and motionless.

"This is the human form of the mother goddess Tiamat."

Merlin introduced:

"Do you see those ropes? Those are the self-inflicted ropes that the mother goddess Tiamat uses to restrain herself. She is indeed lamenting and hating that humans have exiled her because they 'don't need you anymore,' but the mother goddess's deep consciousness accepts it as 'it is inevitable.' And Tiamat, whose origin is 'mother,' still holds the desire to become the protector of humans in the very end, and this self-sealing is its physical manifestation."

After saying this, Merlin paused, crossed his arms, and said softly:

"And my task is to keep this rope going for as long as possible. Haha, don't underestimate me. I'm a candidate for Grandcaster, after all. Don't worry, I will definitely not provoke Mother Goddess again."

"but....."

Gensho looked at Merlin with concern and said:

"After you finish this task, you'll have to go back to Uruk. By then... I imagine the entire route will be overrun by monster hordes."

"Hahaha, Gensho, what are you thinking?"

Merlin paused for a moment upon hearing this, then couldn't help but laugh, looking at Genjiro and saying:

"When the Mother Goddess awakens, my mission as a Servant will end. But I promise you, we will meet again. Alright, time is tight now, go and prepare. I have to set off too. Genji, it was a pleasure meeting you on this trip. If there's a chance in the future, I'll introduce you to my king. That child should like you too, hahaha..."

Your queen? Artoria?

Watching Merlin's departing figure, Genji's expression was somewhat strange. After all, back in the Singularity, he had practically turned King Arthur into a paper doll. Oh well, never mind that, let's get back to the present.

Under Gilgamesh's command, a rather spectacular strategic transfer began. To be honest, the process was not easy, after all, with the awakening of the mother goddess Tiamat, the monsters also began to become active.

Fortunately, due to the replacement plan of the Demon Pillars, the Mother Goddess Tiamat seems unable to produce the legendary 'Eleven Demon Beasts', which were the spider-like monsters with only their gums exposed on their heads that Genji saw when he first arrived at this singularity.

Similarly, the growth and evolution of those monsters seemed to have stopped as well. Therefore, these more troublesome monsters were becoming increasingly rare. During the evacuation, Yuanxiang and Li Shuwen basically focused on killing those monsters. If things went smoothly, when the Mother Goddess Tiamat awakened, Uruk would only have to deal with ordinary monsters.

"Phew... I'm exhausted. Wang really knows how to order people around."

Half a day later, as night fell, in the room Gilgamesh had assigned to the Chaldea members, Fujimaru Ritsuka lay on a bench, stretched lazily, and then sprawled out like a salted fish, looking at Genji and saying:

"Gengo, are you really okay? I heard from Musashi that you were seriously injured."

"I'm a Servant now, and with plenty of mana, I don't need to worry about injuries. You're a Chaldea Master, so this is a very basic question, thank you."

Gengo teased Fujimaru Ritsuka as he accepted the tea Mash offered, thanked her, and then instinctively looked up at the sound outside the window. However, it was nothing; just passing soldiers. In the past half-day, all the soldiers and supplies outside Uruk had been withdrawn into the city. Ishtar and Quetzal Koyatl were currently conducting a sweep outside the city, and with the soldiers taking turns guarding it, the city was currently quite peaceful except for the large number of people.

Therefore, Gensou withdrew his gaze, looked at Fujimaru Ritsuka, and said with a smile:

"So, Dr. Romani, can you hear me? I suggest that after this singularity is over, Ritsuka review the basic courses again."

"Waaaaah!!!"

Upon hearing this, Fujimaru Ritsuka shouted anxiously, trying to cover up Genji's voice. At the same time, Mash's shield on the table flickered slightly, projecting the situation at Chaldea. Dr. Romani, sitting at the control panel, smiled and said:

“Mr. Gensou, you’re right. After we get back this time, we really need to have Ritsuka strengthen her theoretical knowledge.”
