When it came to the use of knockout smoke, Yu Tian’s skill in this area was no worse than those people in the pugilistic world.
As a godly doctor, he certainly knew a lot of herbs that could cause people to faint.
However, he didn’t have these materials on hand at the moment, so using flying needles was the most convenient method for him.
However, after considering it all, using knockout smoke still had an advantage.
Because if they used the smoke, they did not need to enter the target’s room at all, avoiding the possibility of opening the door and windows to wake the target up.
As long as there was a small air hole in the room, they could easily complete the operation of releasing the smoke.
Moreover, the target now had a total of five rooms. Yu Tian and the four eastern ancient martial art practitioners made up exactly five people. Each of them could take a smoke and complete the five rooms at the same time.
