Chen Xuan traveled through the prehistoric times, bound to the sleeping sign-in system, and slept in the realm of Hongmeng Avenue! After the system ran away, he was still sleeping soundly on the top of Taiyun Mountain. The great catastrophe between dragons and phoenixes, the battle between Tao and demons, were all nothing to him. Until Qing Pingjian, the leader of Tongtian Sect, went up the mountain to pay his respects, and was shaken by the Taoist charm around him, causing him to kneel down and practice hard for a hundred years - but Chen Xuan turned over and continued to sleep. This is the daily life of a max-level boss.
