Lu Xingchen is a transmigrator who has transmigrated twice. The first time, he directly transmigrated to the world of Lord of Mysteries, landing as a demigod. Unfortunately, unable to outmaneuver certain cunning old foxes, he could only play with witches instead. The second time he transmigrated, Lu Xingchen arrived in Douluo Continent, thinking he was just a casualty, but unexpectedly, the Chaos Sea transmigrated with him. Lu Xingchen: Things are getting interesting. Hypnosis series, start… oops, wrong. It should be… Brigitte, don't turn around, I am Di Tian. …However, there's one thing Lu Xingchen miscalculated. The people here don't seem to be much smarter than those in Lord of Mysteries. Ya Li: Be my son! Lu Xingchen: ? ? Where did you get that white beard?! I really need to control you properly now.
