"Awakened the incredibly powerful genjutsu Kotoamatsukami, and then just died like that? Uchiha Shisui, do you even know how to play games?" "They just decided to rebel, and then they surrendered after seeing their son slaughter the entire clan. Uchiha Fugaku, are you kidding me, clan leader?!" "And Uchiha Itachi, your son... well, mentally ill people can kill without consequence. You're mentally ill, so what!" Having transmigrated into the Uchiha clan, right after the Nine-Tails' attack, Uchiha Shuichi felt a bit overwhelmed.

He transmigrated to the world of High School DxD and obtained a god-level achievement system. Just as he was considering how to achieve his goal, Orpheus suddenly spoke up. "Let's have a child together." [Ding, congratulations to the host for completing the seven-colored achievement, "Orpheus actively invites you to have a baby!"] [Congratulations to the host for obtaining the achievement reward: Kabbalah Tree!] The Kabbalah Tree, ten primordial elements, four worlds, twenty-two paths, three pillars! Crown, wisdom, understanding, compassion, strictness, beauty... a kingdom! Activity, formation, creation, outflow! "Divine Armor, tenth level! Spiritual reversal, tyrannical ruler!" "This ending, I will never accept, I will never allow! Let it flow into the entire universe, my tyranny, my reason! Let all things restart, eternal return!" "..." Orpheus looked completely innocent: "I just wanted to have a child to defeat the Great Red, why did it turn into..."

Looking at the system in front of him, Tiandao wanted to shout, "Damn idiot! System, do you even recognize me as an Uchiha?"

However, looking at the rewards listed by the system: [Sharingan, Hashirama Cells, Sage Mode, Yin-Yang Release.]

"Since that's the case, then let me see your limits. System, activate it!"

Tiandao, born a commoner, is a mere transmigrator. Watch as he stirs up the ninja world with the help of a mentally challenged system.

Gradually, Sun Cheng discovered that he had become the biggest boss behind this mysterious world full of demons, gods and monsters.

So, some new ideas came up...
