It's unclear if it was due to the Super Serum, but Guan Heng's progress was abnormally rapid. His physique grew increasingly strong and robust. In less than a year, he had mastered all the martial arts skills. In his own words: "This kung fu stuff is the easiest for me to learn, after all, it's something unique to my homeland!",Guan Heng stroked his chin and rolled his eyes, saying, "Lan De, can you give me some intel on who our opponent is",Guan Heng gritted his teeth: "This time, I'll go all out!" Gathering all his strength, his legs suddenly exerted force, leaping towards the top of the cave. Finally, his hands tightly grasped the hilt of the sword. The giant dragon seemed to feel a breath of death approaching, roaring desperately, its voice shaking the walls, almost causing Guan Heng to fall!。
