Lin Bei just wants to make money by running orders. He is a delivery boy and rents a house in an urban village with his brother Zhou Ye. He has twenty-eight years left on his mortgage. That day he was riding through an alley and saw two people with super powers fighting. A child squatted in the corner, afraid to move. Lin Bei put the takeout box away and rushed in to hold the child. A flame shot straight towards the door. Then - stopped. Not being blocked. It's stopped. The flames in mid-air seemed to have been turned off from the switch of the world. The two superpowers froze at the same time. One of the voices trembled: 'What is... Inside you? 'Lin Bei doesn't know either. Later he found out. The thing in his body is called Guixu - the power to end all things. It can end life, end matter, end concepts, and end this world. All forces are eyeing him. Someone wants to seize Guixu and subvert everything. Someone wants to control him. Someone wants to kill him before he loses control. Lin Bei had only one idea: to protect the few people around him. But every time Guixu uses it, he will lose a memory. Start with the most recent events and work your way toward the past. He didn't know how long he could remember 'why he should protect'. A man who could destroy the world chooses to protect it. A person who protects everything forgets something every time he protects.
