The spiritual energy has been revived for hundreds of years, strange beasts are rampant, and humans retreat to the fortress. The fortress is divided into three levels: the upper-level aristocratic families, the middle-level civilians, and the lower-level gray area. The gray area is the garbage dump, the slaughterhouse, and the default sacrifice ground for the upper levels.
Lu Chen, 17 years old, is an orphan in the Gray Zone. His parents died in a wave of alien beasts, leaving only him and his ten-year-old sister Lu Xiaoman. The black boxing ring is his only source of income - a fight is exchanged for half a bag of coarse grains. If he loses, he will lie dead in the ring and be dragged to the landfill overnight.
Once when he was surrounded by the Tieya Gang to snatch grain, his ribs were broken, but he defended the bag of grain. The next day, he found that the place where he was beaten last night no longer hurt, but he became stronger. From then on, he understood: his body could exchange pain for strength.
But this kind of power comes at a price - injuries that exceed the limit will not make him stronger, but will only leave hidden injuries; if the hidden injuries accumulate to a certain extent, they will kill him.
He relied on "transformation of pain" to break through the underground gangs in the gray area, survive the selection of the Federal Martial Arts Academy, and break into the Starry Sky Expedition Team. When he beat Zhao Tianlin, he was not beating one person, but a class monopoly that had been solidified for hundreds of years. When he attacked the top federal officials, he was not fighting for power, but for the man-eating rule of "sacrifice the lives of people in the gray zone in exchange for peace."
His fists hit from the gray zone to the stars. His belief has never changed - to let his sister have a decent meal and live a decent life.
