When Zhang Yi returned discouraged from the fight, but without any injury, all his teammates understood that something had gone wrong in the fights, they waited for a few hours before Zhang Yi recovered and decided to tell what happened.
"I have bad news to tell, it seems that I underestimated the difficulty of this underworld, I have already managed to find out the end of this underworld and even the final strength of the enemies, which is why I was so determined to move fast."
"I had confidence in my strength and thought I could easily destroy this world so we could all go back to the house, but the enemies turned out to be more difficult than I thought and so I found that I can't do it with my current strength."
"So I decided to spend some time training to improve my strength until I have confidence and certainty that I will destroy this world once and for all."
