Although Han Sen had the chance to level up in the holy garden, he did not have enough time alone. He also had not wanted other people to see him in xenogeneic mode. Thus, he chose not to become a true god.
Han Sen was afraid that if he leveled up and did not go into xenogeneic mode, he would only have a battle body. That would have been a waste.
Now, there was no reason for him to be so cautious. Han Sen was not in his xenogeneic body. He only used Jadeskin to push himself this far, but he wanted to take Jadeskin to true god class first.
As soon as he started evolving, his four battle bodies started to change. He did not just level up one battle body out of his xenogeneic mode.
