After traveling to the world of immortals, Su Poman obtained the Purple Source Roulette that could draw out various supernatural abilities.

The first time the roulette wheel was turned...

"Ding, the fragment of Superman's constitution (0.001%) was extracted, and the ability [Photosynthesis] was obtained. It can perform photosynthesis under sunlight to make up for the body's physiological needs without eating. Later, the same constitution fragments can be gradually extracted to synthesize the complete Superman's body..."

The second time the roulette wheel was turned...

"Ding, the ability [Soul Devouring] of the Immortal Reverse World was extracted. The soul will be transformed into a 'Soul Devouring', and it has the incredible fortune to reverse the law of the soul. It can strengthen its own soul by devouring wandering souls, divine souls, and all conscious bodies..."

The third time the roulette wheel was turned...

"Ding, the ability of the Undead Forensic Doctor [Water Resurrection] was extracted. After anchoring the resurrection waters, it can be resurrected unlimited times without cooling or consumption..."

The fourth time the roulette wheel was turned...

"Ding, the [First Generation Pangu Clan Bloodline] of the Zombie Covenant World was extracted, and a synergistic mutation occurred with the complete Superman's body. You obtained the 'Doomsday Zombie True Ancestor' form and have the ability of 'Adaptive Evolution'..."

The fifth time the roulette wheel was turned...

“Ding, the world-devouring ability [Soul Kingdom] is extracted, creating the world within the soul…”

have traveled to the eve of the night of genocide and am about to face the slaughter of the most filial sons in the ninja world. What should I do?

Official version of the introduction:

Traveling through time is a happy thing, and entering a familiar world is even more delightful. This double happiness should be a happy ending.

Unlike his predecessors who traveled here, Uchiha Shinki does not want to save the Uchiha, nor does he want to interfere in the struggle between the Uchiha and the Konoha high-level officials.

Uchiha Shinki only wants to live forever in this world.

But these two dogs, Sarutobi Hiruzen and Shimura Danzo, are really annoying!

Standing on the sterile table: "I'm sorry, Sandaime-sama, it seems that you can only be my experimental material."

In order to survive the night of genocide, Uchiha Nanhe, who had no cheat code, prepared to make his own cheat.

Through constant self-suggestion, when he finally awakened the Mangekyō Sharingan, the pupil of the soul responded to Uchiha Nanhe's expectations, and he obtained the Uchiha's ultimate pupil technique: Izanami, who turned reality into dreams, and Izanami, who turned dreams into reality...

In the world of ninjas, Sai Ueno became an ordinary cannon fodder Chunin, born into a common family, with mediocre chakra and only knowing the basic Transformation Technique.

Faced with the monopoly of ninjutsu, lacking both a ninja clan bloodline and a special ability, in order to survive better in the Second Ninja World War, he could only deconstruct the Transformation Technique using scientific thinking.

While the higher-ups of Konoha were busy harvesting cannon fodder with the Will of Fire, he derived the Beast Mimicry Breathing Technique from the Transformation Technique.

When the genius of the ninja clan was rampaging with their bloodline limits, he extracted the Human Puppet Bloodline Clone from the Shadow Clone Technique.

When the Six Paths' staff clashed with the Flying Thunder God Technique, he derived a quantum teleportation technique that was nearly akin to the Heavenly Hand Power from the Substitution Technique.
