After saying that he bent down and waited for a reply from Yang Lei. He looked like he won't stand up if Yang Lei won't forgive him.
Time passed more than ten minutes later. He Hou still is bending down in front of Yang Lei without any intention of standing up. If Yang Lei won't forgive him.
Seeing He Hou's commitment Yang Lei's anger is reduced and he's ready to forgive him. But he's waiting to see for how long He Hou can continue to be like that.
Even if He Hou is acquired realm peak master. It isn't easy to stand like that for long hours without resting. And it's hard for He Hou to stand for more than one hour.
But past that it requires the tenacious will to continue. As most of them here only practised inner martial arts. Not external martial arts that require hard work and constant pain.
Because of that their endurance is much lower than Wang Wei. So standing like that for more than an hour can make them not able walk easily tomorrow.
