Lu Yi used a Cultivation Technique Level +3 and then a Cultivation Technique Level +4, raising the Yimu Hua Sheng Scripture from Level 3 to the Extreme Level.
The difference between Cultivation Technique Level +1, +3, and +4 is that within the same time of comprehension, the level of the cultivation technique increased much faster.
In just under a year, Lu Yi had comprehended the Yimu Hua Sheng Scripture to its Extreme Level.
Afterward, Lu Yi used another Cultivation Technique Level +4 reward for the Moonlight Immortal Scripture. Since Lu Yi had also been comprehending the Moonlight Immortal Scripture, although he hadn't spent much time on it, and it was only at Tribulation Crossing Chapter Level 2, after utilizing this reward, its level also reached Level 6.
With Lu Yi's comprehension of two Immortal Scriptures' Tribulation Crossing Chapters to Extreme Level, he formed a rough framework in his mind for the Immortal Scripture he wanted to derive.
