Ah Chun was really excited she wanted to reach the pinnacle of heaven's will as soon as possible! "Senior are you able to open up all the meridians in one go or do you have to wait for each breakthrough?"
"You can. It's just that it's not possible on this plane. When you finally leave the lower plane you will find that the Spiritual Qi is almost tens of thousands of times denser than what is available here. Also, there are only one hundred hidden major meridians that I know about. Beyond that, I am not too sure. I have found some information on smaller meridians but have not found any evidence that anyone has been able to open them or not. I do know that as long as you finish opening up your one hundred major meridians you can continue cultivating without any problems. You will have to open sixty-three of them before you can exceed the primordial god realm.
