What Should I Do? the Immortal Emperor Mistakenly Thought That I Was Stronger Than Him.

Wang Nian traveled through the realm of immortal cultivation and became Po Tian Sect, a small gatekeeper disciple. Because he had not made any progress in his cultivation for ten years, he was still a mortal and was known to be ridiculed by everyone. One day the head of the sect passed away. Fearing that his enemies would cause trouble, all the brothers and sisters left the sect, leaving him alone! He became the leader with honor. Wang Nian was also preparing to quit being the leader, but he suddenly awakened to an undefeated system that could gain the opponent's strength and never defeat him. If an enemy clan leader comes to kill him, Wang Nian will never be defeated. An invisible old monster from his enemy came to kill him, but Wang Nian would never be defeated. The Immortal Emperor came to kill him, but Wang Nian would never be defeated.
