Traveling Through Time as a High School Student, What Comes Is the System of Cultivating Immortals!

On Earth, Lu Qing, a good young man in the 21st century, traveled to a world similar to his previous life because of a cos speed bump! And became a freshman in high school! "It has been detected that the host has successfully traveled to the world of immortality, and the super immortality system is being activated!" Huh? Super immortal cultivation system? But this is the end of the Dharma era! "The host successfully deployed a basic formation, and the host is rewarded with the "Complete Collection of Basic Formations for Cultivation of Immortality"! Divine consciousness +5, spiritual power +5!" Huh? What kind of basic formation is it? It's obviously a math test paper! "The host has read a large number of formation books, his own formation attainments have been improved, and he has obtained the formation of immortal cultivation skills. The current experience is 0%!" "The host has read a large number of alchemy books, improved his alchemy skills, and obtained the alchemy skills of cultivating immortals. The current experience is 0%!" "The host has read a large number of weapon refining books, and his own weapon refining skills have been improved. He has obtained the weapon refining skills of cultivating immortals. The current experience is 0%!" … Lu Qing looked at the mathematics, chemistry, and physics textbooks on the table and thought for a while! Can't tell the difference! I really can't tell the difference!
