Yu Cheng transmigrated into the body of the young patriarch of the Whirlpool Clan. Faced with the impending extermination of his clan, he dared not stop for a moment!

Fortunately, his three adopted sons were transported to the worlds of One Piece, Demon Slayer, and Martial Soul, respectively.

And so—

"Old Cheng! Is the Dark-Dark Fruit any good? Hehe... I want to use the Impure World Reincarnation~"

"Come here! Old Cheng, I'm now an Imperial Beast. Which soul beast do you want as your summoning beast? I'll teleport you there!"

"Uchiha Madara wants to fight you? And the Otsutsuki want to join the fray?! Fine, let's fight!! Behold my Sun Breathing!!!"

Several years later.

Uzumaki Yu Cheng transformed into the Demon King, wielding the Supreme Great Sword, stepping on the Black Dragon Emperor, his Rinnegan lowered, looking down at the dying Allied Shinobi Forces.

"From this day forward, the ninja world will be unified. And I... will stand high in the heavens, becoming an immortal god!"

In Douluo Continent, a world where martial spirit cultivation is paramount, Dugu Yuanlong has caught up with the trend and been reborn into the Bilin Snake Soul Master family, the clan of Poison Douluo Dugu Bo. As a reborn individual, Dugu Yuanlong is aware of the problems facing the Bilin Snake family's martial spirit, which explains the family's dwindling numbers. So, where will Dugu Yuanlong go in this world?

Li Fei transmigrated to Douluo Continent, awakening the useless martial soul Blue Silver Grass, with only level one innate soul power! But he wasn't discouraged; at least he had soul power to cultivate, and with persistent effort, he could become a Soul Master in the future. Just then, he awakened a small auxiliary system, increasing his soul ring's age by one year every hour! A three-fold efficiency boost! From then on, he rose from humble beginnings to become a powerful force! ... Yu Xiaogang: How is this possible? Why is Blue Silver Grass so strong?! Tang San: Why is there such a huge gap between my Blue Silver Grass and his?! Tang Hao: Blue Silver Grass can actually withstand my Great Sumeru Hammer! Chen Xin: My Seven Kill Sword was actually suppressed by Blue Silver Grass! Ning Fengzhi: How can this Blue Silver Grass provide such powerful assistance?

Transmigrating into Douluo Continent? This is a good thing! What? I'm just a commoner, my ancestors for three generations all had Blue Silver Grass as their martial soul, and I don't even have any cheat codes. And the protagonist looks down on me. You've already found a way to die... Damn it!! Let's see who has found a way to die. So what if I'm the Blue Silver Emperor? I'm the God of Blue Silver Grass! "Watch closely, this is the correct way to use Blue Silver Grass," Lan Jiu said. "Watch my Grass Sword Technique, one sword opens the stars." "As long as one blade of grass remains, I will not die."
