Chapter 114 Overlapping Trajectories and the World in My Eyes
In Fang Yi's eyes, victory is a rigorous and scientific thing, and the process of defeating the enemy is more like the process of solving a puzzle.

There are naturally multiple solutions to the puzzle, but once you find a formula that meets your own conditions, fill in the conditions required by the formula, and conduct reasoning and argumentation, victory will naturally be within your reach.

Obtaining enemy intelligence, inferring enemy movements, predicting opponent's trajectory, sensing the opponent's threatening moves, and knowing the opponent's trump cards are all prerequisites for finding victory.

As long as all the conditions are collected, the winning formula will naturally come to mind. Fill in the conditions you have, and the next step is to choose a plan.

But Fang Yi is a very greedy person and a perfectionist. He hates losses, or in other words, if he has a choice, he doesn't want to sacrifice some people who are kind to him to achieve his own goals.

He would rather have a perfect ending and save everyone at the same time, even if it means increasing his own burden, he is happy to do so.

"I had no regrets in my previous life. After rebirth, I still chose boring and ordinary options like ordinary people. So why bother starting over again?"

[Since I have unique intelligence in my head, so many advantages, and I also have this talent, I must create a better and more perfect ending.]

[Because I am Fang Yi, this is the oath I made and the promise I made, so I will definitely complete it and find the best solution among countless options.]

Fang Yi looked at all the enemies in the arena, and the world slowed down again in his eyes, as if time had stopped, giving him enough time to think, just like when he stepped out of the stronghold and saw enemies all over the street and saw Xiong Yue's sword.

Under the influence of this ability whose activation conditions are unknown and whose effects are currently unclear, he has plenty of time to think about what he can do, find a solution, and then complete it.

After one third of a second, the thunder of [Accumulated Fury] will fall, blocking your position.

One and a half seconds later, Chen Cheng's knife will touch his body.

After three quarters of a second, Ai Jue's spear will block the area around him.

One second later, the blood demon art of Upper Five, Jade Pot, will take the life of Mitsuri Kanroji who is trapped and unable to move in the [Blood Demon Art, Blood Prison Bowl].

One and a third seconds later, [Cola] will also blow out a strong wind to compress the dodging space of Rengoku Makijuro and Nakamori Yuto, and [Kora]'s claws will be in contact with the body of Nakamori Yuto who is already seriously injured and unable to dodge.

And you can only choose one of them to solve.

Of course, no matter which option he chooses, he will not die, but it means exposing the resurrection ability of the [Five Emperors' Coins] in front of the ghost, letting Muzan Kibutsuji know this trump card, and it will be difficult to trick this cowardly and despicable ghost king.

At the same time, there is a very small chance that [Reversal Technique] will not be able to save teammates.

It's probably about 0.01%, which is lower than the probability of some surgeries.

So is it possible to do all of the above at the same time?

Fang Yi was thinking in his mind. Although he originally had Plan A which was to use the Five Emperors' Coins, he was now trying to find a better plan.

After a moment, he remembered that there was a mortal who had used sword skills that he could try to learn from.

Since I have already thought of the method at this moment, I meet the requirements and know the principle, then theoretically I can use it. I just need to master this technology and build the "reasoning" process.

Under the effect of this unknown skill, Fang Yi already had a premonition that this time he could skip the reasoning process and directly obtain the 'answer' to victory.

Since there is such a better option, there is no need to use Plan A of using the [Five Emperors' Coins] to revive.
-
The solution Fang Yi thought of at this moment was to use the principle of [Secret Technique·Swallow Return] out of thin air by taking advantage of the rare situation and get rid of [Ai Jue], Chen Cheng, and Yu Hu at the same time.

Then after this move is over, find an opportunity to kill [Kora] and [Cola], and use [Reversal Technique·Strength] to heal Nakamori Yuto who is about to die.

[Secret Technique: Swallow Return] is a sword technique that appears to be holding one's breath and swinging three swords to block the enemy's movements. In fact, this sword technique involves ignoring the concepts of space and time.

Although he is nominally the heroic spirit of Sasaki Kojiro, he also considers himself a mortal.

“Actually, this isn’t a very powerful move.”

"It's just that I happened to want to cut down a flying swallow in the air, and I took advantage of the opportunity to master the [technique]."

"The knife in your hand is just a straight line. It is impossible to catch a swallow flying in the air."

"However, if there were two or three such [lines], it would be different."

However, this 'technique' for slashing flying swallows in the air actually involves the [Multi-Dimensional Distortion Phenomenon], touching upon the magical realm of the [Second Law] of the Type-Moon world, which is a parallel world.

The principle is speculated to be that at this point in time, the self in the basic world slashes vertically, and at the same time goes to the parallel world 1 at this point in time and slashes horizontally, and finally goes to the parallel world 2 at the same time and slashes sideways again.

The three are superimposed and merged to form three swords swung simultaneously by oneself in the basic world at the same time.

It is much more difficult than what Sasaki Kojiro himself described in his own narration of the training process, which is "It requires holding your breath and overlapping it to achieve it."

Well, since I already 'know' the principle, I am also a 'mortal' and I also master swordsmanship, then I can use this unknown temporary state to do the same thing.
-
Looking at the hideous and terrifying [Ai Jue], Fang Yi's heart remained calm. The spear was still half a meter away from him. He had already captured the opponent's strange trajectory in advance by using [Blood Demon Art·Eye Hidden].

There was a hint of cunning and ferocity in [Ai Jue]'s eyes, but in Fang Yi's view, it was nothing but a meaningless struggle.

Fang Yi moved as fast as lightning, and swung a knife along the ghost's neck elegantly and casually.

In an instant, the knife light cut through the air like mercury, carrying a deadly chill.

This ghost's level is slightly higher than the Lower Rank, but a little lower than the Upper Rank Six. In a one-on-one fight with Fang Yi, he is quite weak.

In Fang Yi's eyes, there are countless ways to kill him, so he can just pick one at random.

This is the first cut.

After dealing with [Sadness] and returning to the original time point, Fang Yi looked at the sprinting Chen Cheng, his eyes narrowed slightly, and he began to silently comment on his opponent in his mind. Chen Cheng was not a good-looking person, with ordinary and even slightly ugly facial features, nothing special.

But it must be said that his strength is not to be underestimated. His swordsmanship is very well-trained. During their previous fight, his sword strikes were sharp and experienced, showing years of hard work and practice.

"Chen Cheng's swordsmanship is indeed not simple." Fang Yi thought to himself.

He knew clearly that he could not be careless when facing such an opponent.

[Blood Demon Art·Eye Hidden] cannot capture Chen Cheng's figure, [Fighting Spirit Perception] can barely perceive him, but the information provided by the above two skills is not enough.

However, you can still see the other person's muscle movements, and therefore can infer the other person's actions.

Now that you know the other party's actions, there will naturally be a corresponding solution.

In this state, even in a one-on-one situation, there are only three ways to kill Chen Cheng.

All three methods require a certain price to be paid.

【Then choose the one with the highest price】

Fang Yi turned sideways and faced Chen Cheng's charge, swinging his sword at the cost of his mask being shattered by the opponent's sword energy.

The knife was ordinary, without any dazzling cold light or any fancy special effects. With just a casual swing, the blade cut through the air and pointed directly at Chen Cheng's throat.

Fang Yi controlled the speed and strength of the sword swing just right, without any excess force or drag.

[This is the second knife, there is still a chance for the last knife]
-
Fang Yi looked at the Upper Five, Jade Pot, in the distance, estimated the distance, and thought about how to deal with it and save Mitsuri Kanroji at the same time.

Jade Pot, the fifth of the Upper Moon, is still in its initial form.

The body of the jade pot is connected to the pot. The upper body is muscular, but it has no arms. Instead, several small arms grow from the head and other parts.

In this state, it can move in space between its own pots.

However, this ghost has poor perception ability and is arrogant and proud, making him a shameful upper-rank ghost.

In the original work, he is the only upper-rank demon who was killed by a "pillar" alone.

Now it was admiring the Mitsuri Kanroji who was about to suffocate in the water ball wrapped in its [Blood Demon Art·Blood Prison Bowl]. It distracted its attention and gave Fang Yi the opportunity to kill it instantly with one sword.

This ghost had a habit of admiring the corpses of drowned people, so he did not kill Mitsuri Kanroji immediately.

Because the swordsmen of the Demon Slayer Corps need breathing techniques to instantly strengthen themselves, if there is insufficient oxygen in their lungs after being wrapped in a water ball, they will naturally have no ability to resist and will not be able to exert their combat effectiveness. Without anyone to help, they can only wait for death.

Looking at Rengoku Chijuro who was trying to destroy the water wall of [Blood Demon Art: Blood Hell Bowl] with a knife.

Fang Yi instantly understood that Mitsuri Kanroji, who looked physically strong, was tricked in order to protect Senjuro Rengoku.

There were still poisonous stingers with nerve-paralyzing effects on her body that were spit out by Yu Hu using [Blood Demon Art·Thousand Needles·Fish Killing], which caused her to be trapped by [Blood Demon Art·Blood Hell Bowl] and about to drown.

[Then I will remove Yu Hu's head with one strike, and at the same time break through the water wall.]

Chen Cheng has just demonstrated the use of the 'real full concentration' breathing method. It doesn't seem difficult, so just use it directly.

Fang Yi was ready to go, his eyes were like lightning, and his aura was concentrated in an instant.

His body seemed to merge with the air, and suddenly, he disappeared.

The next moment, he appeared behind Yu Hu and took the other's head with one knife.

The knife flashed, and before she could react, she was still admiring the jade pot of Mitsuri Kanroji who was about to drown, a fatal wound appeared on her neck, and blood gushed out like a fountain.

As Yuhu's head fell, the world in its eyes was about to turn upside down.

Fang Yi originally planned to let Mitsuri Kanroji fall freely and save Yuto Nakamori at the same time.

However, when he turned his gaze to Nakamori Yuto, he found that the opponent's sword was igniting with fiery sparks, and the blade gradually turned red, as if absorbing energy from the air.

Nakamori Yuto stood there with a firm look in his eyes. His hand holding the knife trembled slightly due to the gathering strength. The sparks on the blade kept jumping and then began to burn, and he was about to kill the two clones of Hantengu.

[You opened it too? Then I don't need to do anything.]

Fang Yi chose to take Mitsuri Ganluji out of the water, turned to Chen Cheng and showed his face, ready to appreciate Chen Cheng's expression.

So, let's start overlapping.

The world in Fang Yi's eyes returned to normal.

　Sasaki's Swallow Return is not as strong as Fang Yi's this time.

　　The effect of the Philadelphia shooting created by the President's D4C in SBR was also referenced.

　　At the same time, the users of the second method are unique, that is, there is only one Fang Yi in all parallel worlds.
