“I, an Immortal Cultivator in this world of superheroes, alone understand the Dao.”Elius Northrim had a peaceful life—until he blacked out and awakened with tragic memories of his past life.Along with those memories was a realization that in his eighteen years, he was living in a brutal superhero universe, and his ruthless alien father—whom he had never met and a SUPERMAN equivalent of this world—was coming for his life because one of his brothers, the main character of the comic awakened his Solarion bloodline.Surviving while being mistaken for an awakened Solarion offspring of his father too, Elius must keep the truth hidden—he’s not one of them, but an immortal cultivator.If his father discovers the deception, both he and his mother will die.But the worst part is that he has become his father's favorite among the two. To avoid being constantly under his father's watch, Elius enrolls in a superhero academy, blending in while secretly growing stronger.However, with rival students, watchful instructors, and his father’s looming presence, one mistake could mean death.Now, he must master his powers, play his role, and survive—before his secret is exposed as a lone immortal cultivator in this world of Superheroes.

“He” was originally a weak and pitiful “sissy”. Once reborn, he became an ancient martial arts genius with both medicine and poison. The national male god.

Don’t touch anyone who belongs to her, and she will hold what is not her, and she will never be merciless when she abuses scum and face.

He is a business genius who covers the sky with one hand in Huaguo. He has a dark belly and is decisive in killing. He is the only one who turns into a loyal dog in front of her.

She kills, he sets fire. She poisoned, he silenced.

One day, the pampered and lawless Lu Xingchen said in disgust, “Brother, they all say you are my dog.”
