On the day of the college entrance examination, Chen Yuan's fiancée Lin Qingxue announced in public that she had terminated her engagement. Her new boyfriend, Wu Zhuangyuan Li Xuanji, destroyed his Dantian with one palm. "Don't delay Qingxue, you trash. Physical training? You will be a brick-and-mortar in this life."
Everyone thought he was finished.
Sent to the seventh pass city on the northwest border, his daily task was to resist the impact of low-level monsters with his body and buy time for the hot weapons at the rear to aim. The mortality rate is 60%, and the average survival time is three months.
In the third month, an armored rhinoceros hit his chest - seven bones were broken, but when the rhinoceros horn shattered, a hot life essence poured into his body. He clearly felt that the broken bone healed within ten seconds, and its density tripled.
System? Unnecessary.
This world is his melting pot, monsters are his forging hammer, and flesh and blood are his magic weapons.
A year later, the innate monster broke through the city, and the captain asked him to escape. Chen Yuan used his chest to receive a claw forcefully, but the skin was not broken. Then he punched the innate demon beast's head.
Three years later, there was a saying spread in the ten major border cities: There was a madman at the seventh pass. He didn't carry weapons or wear armor. He rushed into the demon tide and took a bath. After washing, he didn't even have a scar on his body.
Ten years later, the Demon King personally led a wave of millions of demons to invade the eastern coast. The strong human race fell like rain, and most of the S-class strong ones withered. In despair, someone saw a shirtless young man walking back on the western border carrying the body of a demon king.
"I heard something happened at home?"
He crushed the demon king's body into pulp and punched through the three thousand kilometers straight passage from the border to the East China Sea.
Before the Demon King's head exploded, he heard the last words:
Physical training? What I am cultivating is the backbone of the human race.
