Seeing Qin Yu's serious expression, Tan Liu could only nod.
The next day, Tan Liu left the place, while Qin Yu chose to stay and wait for the end of their mission.
These few days, Qin Yu did not waste time. He sat there with his legs crossed, cultivating slowly.
As for how to get the dark energy, Qin Yu planned to figure it out after he returned to Thunder Courtyard.
Another two days passed.
Qin Yu's inner demons acted up again. This time, he took out the bottle from the magical artifact without hesitation and swallowed a few primordial spirits from the bottle.
After devouring the primordial spirits, the primordial spirit in Qin Yu's mind became even more powerful!
It was no exaggeration to say that Qin Yu's primordial spirit was only a step away from the Reversion Void stage!
