Not only Wang Ba, but also Hu Zaixi has caught on, a sudden realization flashing in his eyes:
"I see... these are the pros and cons of the Dharma Lineage dual cultivation of other cultivation methods."
"The mana whirls of dual cultivation will be accelerated, thus, the speed of mana refinement will be extremely fast... That's why the Dharma Lineage can afford the time to cultivate so many techniques at once."
"But because of this, the difficulty of cultivation has increased. Without sufficient control, I'm afraid it would be impossible to dual cultivate any technique."
However, although he realized this problem, Hu Zaixi didn't have any better solution. It is not possible to rely on others when it comes to cultivation.
He could only come to Wang Ba's aid in case his mana whirl became out of control.
At least in the early stages, when the mana whirls aren't stable enough, this was the only way.
He also conveyed his thoughts to Wang Ba.
"Control of mana?"
