Bab 1775: Primordial Sacred Edict and The Battle of The Great Dao (3)

Then, he began to refine the Spirit Sealing Array and the Earth Array roughly according to the method taught by Yan Wuyu.

Why was it called refining it roughly?

This was because the requirements for materials were extremely high, especially for the Spirit Sealing Array. Even Yan Wuyu could not afford it.

Fortunately, Xu Tui did not learn this to refine the Spirit Sealing Array and the Earth Array that he could use to save his life. Instead, he wanted to learn these two array abilities. Then, through the abilities of his powerful School of General Senses, he could replicate these two arrays and increase his combat strength.
