The reason why Qu Tiange rushed to the closed-door training was that something big was going to happen in the cultivation world.
In her previous life, Mountain Sumeru arose, which caused a sensation in the whole cultivation realm. After all, there had been no other Secret Land for thousands of years in the Canglan Realm. Every time a Secret Land was born, it meant unknown resources and merits. Although it was accompanied by unpredictable danger, it still attracted countless people.
Qu Tiange couldn't go there in her past life. Mountain Sumeru only allowed cultivators whose cultivation levels were higher than the Golden Core and lower than Yuanying. Her cultivation didn't meet the prerequisite.
