Three days

It has been three days since the tournament where Ren showed his might to everyone in the Void Sect. After the incident surprisingly enough Ren didn't kill Ming Hao or Elder Ming or anyone for that matter instead Ren simply destroyed Ming Hao's dantian, so now he could no longer gather Qi and became a human who could not cultivate the Void Sect's arts. As Ming Hao was falling in despair Ren spoke to him. 

"Hmph, this is already a light punishment for what you have done. I hope next time you won't do something so cowardly. If you wish to fight or kill my disciple do it upfront." 

When Ming Hao heard Ren's words the fear he felt for the other person was replaced with a fit of intense anger. Upon losing his dantian he became nothing more than a mortal with no power and here in the upper realms were Gods and Ancient beings reside, being a person that could not gather Qi was equivalent to being a dead person or a person forever protected by others.
