"Bang, bang, bang …"

At the foot of the mountain, in a forest, a well-built man was flying through the forest. He was fast and agile like a cheetah. As he ran, he punched the surrounding trees, creating muffled sounds like thunder.

It was a fifteen or sixteen year old boy, bare-chested, his muscles well-proportioned and fit, his skin healthy and shiny from years of sun exposure and exercise, looking extremely beautiful. After practicing for a while, the boy's body was covered in sweat, droplets of sweat trickling down his body.

Suddenly, the youth withdrew his fist. He had thought that he would end his training this time, but unexpectedly, he stomped hard on the ground and his figure suddenly shot forward like a cannonball towards the nearest tree.

Just as he was about to hit the tree, the youth did not dodge. Instead, he charged straight at the tree!

"Bam!"

The boy's chest and body collided head on with the large tree, and a deep red bloodstain immediately appeared on his body. The strong rebound caused the youth to frown, but his two feet continued to step on the tree's trunk, borrowing the huge rebound force to send his body flying. In an instant, his back came into contact with another large tree, causing a deep muffled sound.

Before he could finish, the young man stomped his feet continuously and his entire body flew in the forest. Bang! Bang! Bang! The sound was unceasing and was mixed with some muffled groans.

After an unknown period of time, the youth's body, back, arms and legs were covered with countless wounds. Fresh blood immediately began to spill from some of his wounds.

Just as the youth landed on the ground, the muscles in his thighs suddenly tensed up. He looked at a big tree three meters in front of him, and his black eyes flashed with a sharp light.

"Boom!"

With a loud bang, the tree shook violently before coming to a stop.

Suddenly, a series of light "ka ka" sounds were heard. It was the sound of the boy knocking his forehead against the trunk of the big tree. Cracks immediately followed, and the cracks became bigger and bigger, spreading faster and faster. In the blink of an eye, the entire big tree broke in half and crashed into the ground!

The youth rubbed his head and grimaced in pain. However, if one looked carefully, his forehead was actually completely undamaged. This terrifying defensive power!

This young man was Ling Yan, who had found a job at the slaughterhouse and spent his free time cultivating the « Berserk Golden Body Art » at the foot of the Great South Mountain.

With the end of the last blow to the head, Ling Yan's training today came to an end.

Arriving beside a huge rock, Ling Yan took out the healing herbs he bought from his bag and applied them to the wounds on his body. He then sat down cross-legged and closed his eyes.

Ling Yan opened his eyes as he spat out a mouthful of impure air. His eyes were brimming with vigor!

In a week, under his desperate training, he exhausted all of his healing herbs and finally stepped into the Small Success Stage of the First Stage of the Mortal Stage. His strength actually reached a thousand pounds!

In addition to the full strength of his body, the defensive capabilities of his body had also risen by a level, especially that of his forehead.

After cultivating his body, which part was hardest on Ling Yan? It wasn't his fist, nor was it his leg, but rather his brain!
