Lian Xiaojian laid on the ground and rested for a bit.
His energy had been sapped by the latest attempt and he would need to rest for a while before trying again. He had been given these instructions long before and knew exactly to follow them.
But Lian Xiaojian couldn't rest too long either. He needed to make sure that his body was constantly under a certain level of stress. If that threshold of fatigue and injuries was exceeded or underwhelmed, he would be unable to have any success.
This was something he had learned from the constant battering of the formations. He had realized that the attacks would intensify whenever he was well rested and ease up when he was reaching a certain level of exhaustion.
If his injuries also reached an extreme level, he would be sent flying back. While the final attack may seem powerful, it inflicted the least injuries and mostly had a knock back power in it.
