Li Letian, a grassroots young man, accidentally acquired a chatty fox demon and embarked on an interesting path of cultivation. While he is clinging to his old laurels to survive on a daily basis, he also has fantastic ideas, which can always stir up the situation by mistake. With the help of his partners, he has had the last laugh many times in sect competitions, spiritual realm adventures, and battles between good and evil. During this period, the quarrel with Su Panpan became happy, and love secretly emerged. The evil genius Qin Changfeng presses harder and harder, and the struggle between good and evil is reversed one after another. In the crisis-ridden troubled times of the Three Realms, Li Letian relied on his humorous nature, on-the-spot wisdom and unyielding spirit to finally break through the imprisonment of heaven and become the true king of Funny, and the Three Realms respected laughter.
