章 978: Striking Down Yin Devil Sovereign

Li Yunmu continued sitting and studying Heavenly Emperor Ryukyu's notes. One month passed like that.

During this time, the system told him that if he used the experience points, the notes could be directly imprinted in Li Yunmu's brain, but he rejected this proposal.

After all, he wasn't only studying the notes but also experiencing Heavenly Emperor Ryukyu's difficulties and experiences.

Three more months passed before Li Yunmu closed the notebook and carefully packed it inside the heavenly world. It was the final object left behind by Heavenly Emperor Ryukyu, and Li Yunmu was extremely cautious so as not to ruin it.

Once finished, he stood up and quickly searched for the teleport portal in the void. Heavenly Emperor Ryukyu had already explained how to use it, and Li Yunmu soon disappeared.
