Zhang Lan traveled through the Qin Dynasty and became an abandoned baby. Because of his unnatural understanding, he was snatched away by three giants including Gui Guzi and ended up in the Gui Valley. He used the Guigu Breathing Technique to understand the immortal cultivation technique, the Zonghengheng Sword Technique to create the Heaven-Slaying Sword Technique, and even acquired magical powers. "Fellow Taoist, please stay." Later, he learned from hundreds of schools of thought and led the world to a higher level. Even Ying Zheng asked to be his disciple.
A very nice book
