Frozen for Thousands of Years, the Whole World Begs Me for Inheritance

In 2157, the earth entered an ice age. Because of the cold weather, supplies gradually became scarce. At that time, a large number of humans entered the hibernation chamber and decided to wait until the Ice Age passed before waking up. Li Xu was a member of the hibernating army at that time. But when I wake up... The world has passed exactly ten thousand years. The world has undergone tremendous changes, demons and monsters are in chaos, and the human race is weak. But when he woke up, he was regarded as a true immortal by future generations and worshiped by the world. Now he looked confused. Li Xu tried to explain that he was really not an immortal. Just lived for ten thousand years. What cannot be explained is: The talismans he drew at random can suppress demons! The tactics taught at will can kill the demon king of the world! The mental method taught at will can make people transcend the ordinary and become holy! The calligraphy and painting you write at will can transform mountains and rivers! … Li Xu didn't understand why the world admired him so much. The advantage between a mortal and a demon is clearly not in his. How could he change the world just by teaching something casually? Has the golden age of cultivating immortals begun? Until the Demon Emperor arrives and the demon army counterattacks... At the request of the people... He came out to challenge fearfully. In the end, one person and one sword defeated the demon! Kill the demon emperor and end the troubled times! He suddenly realized ——It turns out that I have already become a saint in my body.
