Taurus decided to go into the Temple and try to cultivate there. The air in the Celestial plane was saturated with so much Mana and yin energy and it would take years for the meridians to properly clean and purify it before the Xian can start using it. That was what Taurus figured out when he can to the Temple. When he came here five years ago he was still at the GrandMaster first stage but in just five years he was able to move to GrandMaster stage two! That was an insane level of cultivation!
