In the middle of the Holy City, there stood a nine-story tower. Inside the tower, the speed of cultivation would be much faster than outside. It was said that the higher the level, the faster the cultivation speed, but the more Dark Stones it required. Everyone in the Holy City had a chance to go in and cultivate, but they had to have enough Dark Stones to enter.
Even for the first floor, cultivating inside for a single day required ten pieces of Low Grade Dark Stone.
Yesterday Mo Liancheng had given him those things; exchanging them for Dark Stones would be enough for Xiao An to cultivate for a period of time.
