Ever since the last alien invasion, Clark had been plagued by a deep sense of unease.
He had come to fully realize just how dangerous this world truly was.
Simple weight training could no longer drastically improve Clark's physical fitness in a short period of time. If he wanted to rapidly increase his strength, he could only seek another path.
So Clark went to Dilos for help.
And so, Dilos taught him a set of Chinese martial arts that Clark had no idea where he had learned.
To be honest, Clark had initially been worried whether this kind of training would even work on his alien body. After all, his body was vastly different from a human's even at the genetic level.
But later, Clark realized he had been overthinking it.
In the end, vital energy was simply the body's bioenergy. Any living creature could extract the bioenergy within its body through training. Though it sounded easy, learning how to extract that bioenergy was exceedingly difficult. Without someone teaching you step by step, you might spend years or even decades without ever mastering it.
Even so, with Dilos personally guiding him, Clark still spent several days before he finally learned it. Yet even after learning, the extraction process was not as easy as he had imagined. He had to assume the special stances and use the martial techniques Dilos had taught him to facilitate the process, while also calming his mind and guiding the extracted vital energy throughout his body to temper his flesh.
To accomplish that, Clark's absurdly overpowered body was practically an obstacle. Before he had become proficient at extracting vital energy, his powerful physique made it impossible for him to feel fatigue. He could not even sense the vital energy he had extracted. To solve this problem,
