Zhao Hai didn't know that Dao Baiying had started to pave the way for him. To be honest, he didn't expect Dao Baiying to be so generous as to solve his trouble in advance.
As a matter of fact, Zhao Hai didn't really care about tie Chui. Tie Chui was just a small team leader. What could he do? Zhao Hai had already thought it through. He was able to join the blade guard Army this time because of team leader Feng. Therefore, if he joined the blade guard Army, he would probably be team leader Feng's subordinate. He wouldn't have any interaction with tie Chui, so he wasn't worried.
After returning to the Academy, Zhao Hai rested for a while. Then, he went to the research team. To be honest, even though their research was not long, they had someone to back them up. That person was Dao fuliu. He had been in this field for a long time and had a lot of valuable information. Now that he had given all the information to Zhao Hai and the others, they could avoid many detours.
