Chapter 200: The Collective Self-Destruction of the Three Great Mages of the Astral World!

Three books that emitted a special golden light appeared in his backpack. Li Cheng was delighted.

Knowledge of the Astral World was extremely desired in the entire main plane, as well as countless Gods. After learning it, one could strengthen the attributes of all units.

Low-level knowledge could be sold for a sky-high price. As for high-level knowledge, he had never heard of its existence even when he had fallen in his previous life. If this news were to spread, the entire continent would shake.

Thinking of this, Li Cheng did not hesitate and directly chose to use it. The notification sound of the system rang in his ears.
