Ji Yutu, an ordinary college student, was reading the old book "The Classic of Mountains and Seas" left by his grandfather in a rental house. He fell into a dream and traveled to the real world of mountains and seas. He landed in Si Youguo, a small tribe on the coast of the East China Sea. He rose from a powerless nerd step by step to dominate thousands of mountains and beasts and became the king of men. When he finally woke up from the dream, it was difficult to distinguish reality from reality.
