On the night he finished watching the ending of Honkai Impact 3rd, veteran captain Su Bai was about to turn off his computer and go to sleep when a bizarre pop-up blocked his way—"Do you want to start a new journey?" The options were "Yes" and "Want." He clicked on it casually, and when he opened his eyes again, he was lying on the grass in Teyvat, with a Hilichurl charging towards him wielding a club!

At this critical moment of life and death, a "ding" sounded, and his invincible path officially began: he gained the power of the Herrscher of the End immediately upon signing in, crushing all opponents in Teyvat with his strength. But Su Bai's ambitions went far beyond fighting—he held the resurrection item given to him by the system and personally awakened those characters whose fates were so tragically shattered: Gui Zhong, Yasha, Raiden Shin, the Great Tree King… He would make up for all the regrets!

And this is just the beginning of his journey. Starting from Teyvat, his footsteps have reached countless worlds: building the "Herrscher Academy" in Honkai Impact 3, fighting against the Star God in the Star Iron Universe, and rewriting tragic endings in countless anime worlds. This is a healing journey that transcends dimensions, and also a joyful story about how to build a cross-world family after becoming invincible.
