Zhao Hai had no idea what was going on with han buli and the others. Although he had placed a needle on han buli's body, the needle had been removed from han buli's body the moment he entered the house.
Zhao Hai was very clear that han buli would not come to the rare metals Division for no reason. This place must have a very secret relationship with the dark group. If that was the case, if the mercury needle followed them in, it was very likely that they would be discovered. He would rather not know what han buli was up to than take the risk.
Moreover, he was currently preparing for the Grand competition. There was only a month's time left before the Grand competition. He had to make good preparations.
These days, Zhao Hai had been practicing in the medium. He was not practicing how to kill enemies, but how to act. He wanted to get an average ranking in the outer sect competition, so he had to act well. Otherwise, others might see through his act.
