Since he couldn't leave, Lin Shen devoted himself to understanding all kinds of knowledge on Celestial Court, realizing that the more he knew about Celestial Court, the more help it would be to him in the future.
Lin Shen suddenly discovered a problem with his Evolution Theory. Although it had been modified by himself and fit his situation perfectly,
the effectiveness of Evolution Theory could only reach Nirvana Level.
Originally, Lin Shen thought that reaching Nirvana Level with Evolution Theory should be sufficient, considering that advancing to Immortal Level depended on the comprehension of Immortal Laws, which wasn't closely related to Evolution Skill anymore.
But in reality, that was not the case. After studying Divine Being Techniques, Lin Shen realized that Immortal Level still required cultivation.
Immortals from Ancient Realm didn't need to cultivate, which was because they had no subsequent Cultivation Techniques and believed that Immortal Level was the pinnacle.
