The Heavens Descend, Starting with Douluo

The blue star changes strangely, and the heavens descend. The lives of urban cows and horses are broken by three strange worlds that suddenly descend from the sky: a perfect world that revives night and mystery. For the first time, 30,000 people were selected to enter the trial. Six months later, only 32 people came back. At the same time, 4 new worlds appeared: Panlong, The Other Side of Deep Space, Taiping Nian, and Douluo Continent. You can only choose one of the seven worlds. Which one to choose, wait online, it's quite urgent!
