Losing his strength wasn't a big deal to Lin Yi. As long as he had time, he could recover. Of course, if it was in a dangerous situation, he could only use it when there was no one to disturb him and no danger.
As for the second level, it was actually a three-person combination attack-from two to three, from two to three, and from two to one to three. If three Earth Class early phase peak were to combine, they'd probably reach Sky Class, and fighting Sky Class early phase wouldn't be a problem.
Of course, some people would think that two Earth Class early phase peak together could reach Earth Class late phase peak, but how could three Earth Class early phase peak together just reach Sky Class and only be able to fight against Sky Class early phase?
