In Han Zheng's eyes, Yuwen Xizhen was nothing but a fool, both evil and stupid.
He had willingly consorted with the Poisonous Flood Dragon Demon Lord to profit in a time when other powers of the Martial World suffered heavy losses; although evil, he at least managed to harm others for his own gain.
But afterward, he chose to drink from the Eternal Youth Spring to gain strength, which was simply foolish behavior.
Zhao Rongye had drunk from the Eternal Youth Spring due to severe injuries, in the hopes of extending his life.
Whereas Yuwen Xizhen did so purely to become stronger.
The problem now was that he had turned himself into something neither human nor ghost, blocking his own path to ascension, and it was doubtful he was much stronger for it.
Although drinking this substance meant he did not need to practice bitterly, it was tantamount to completely ruining his own Martial Arts practice with no chance for further advancement.
