After a Strange Recovery, I Was Attacked by the Deputy.

Shen Mian, a patient with dual personality, the leader of the Shen family, the flower of the business world. But Mr. Shen, who looks calm and dignified on the outside, is not interested in wealth and power at all. He has always controlled power just so that his weak and pitiful alternate personality brother can enjoy a beautiful and happy life while using his body for a short period of time. However, after a man-made car accident, he "died" mentally and disappeared completely. The secondary personality opened cold eyes on his body. … A month later, the strangeness revived. For a time, countless terrifying beings were born in the world, and human cities fell one after another. The ten most powerful, mysterious, and unexplorable contaminated areas were known as the ten weird restricted areas. But hope was also born among humans, and people with super powers emerged one after another. The SSS-level superpower "Shen Mian", codenamed [Return to Zero], is one of the strongest humans, but has a vicious and cold-blooded personality. He can be called a humanoid killing machine and is feared by no one in the survivor area. … [Abyss], one of the ten most bizarre forbidden areas in the world. But when [Abyss] woke up, before he could see the world clearly, he saw a man in black with a knife appearing in front of him. This man looks very familiar. Humans call him [Gui Ling], and [Gui Ling]'s human name is "Shen Mian". [Abyss]: "?" Isn't this the name He used when He was a human? Oh! This [Return to Zero] body is also the body He used when he was a human! … People know [Return to Zero] is strong. But when I saw [Return to Zero] chasing the top ten restricted areas [Abyss], I was still deeply shocked. "What? Is the restricted area also movable? Has the restricted area become stronger again?!" "Isn't the point of it that even the restricted area can be scared away by [Return to Zero]! Then how strong must [Return to Zero] be now?!" … The sleep that remembers everything: The younger brother with the secondary personality used to pretend to be weak and pitiful in his body every day, but he is actually a crazy and cool guy with a strong sense of oppression who can kill through restricted areas... Now that I have inherited his body, I want to use his body to attack him :) Still not running? … People don't know why [Return to Zero] insists on going to the polluted area called [The Abyss]. If this continues, sooner or later, [Return to Zero] will be assimilated into pollutants. Indeed, no one will understand that the polluted area that people are fleeing from is the last piece of pure land he protects. … The elite beauty is attacked by her crazy younger brother, who defeats her superiors. He can't fly if he runs away or chases him. Purpose: love and protection
