With the Guan Dao in his hand, Zhao Hai attacked the stone Scorpion. Although Zhao Hai had never learned how to use the Guan Dao in the true spirit world, it didn't mean that he didn't know how to use it. Don't forget, Zhao Hai had bought a few background books related to China in the medium. In those background books, Zhao Hai had not only found Buddhist scriptures, Taoist Scriptures, and other things, but also many secret martial arts books. Among them was the secret book of the Guan Dao, and even the spring and autumn sword technique of the Guan family.
However, Zhao Hai did not pay much attention to the secret martial arts manuals on earth before. This was because he had advanced in the world of self-cultivation. The attacking methods he used were completely different from the martial arts on earth. The martial arts on earth could only be used as references and not as an attack.
