Listening to Lin Mu's words, Xukong understood that the technique was not as simple as the Mortal Strengthening Scripture.
"But that's not all is it? It absorbed a part of the meteors." Xukong asked Lin Mu.
"Yes, it can absorb materials. Its one of the ways it grows stronger. And also how I'm supposed to unlock the other qi skills." Lin Mu replied.
"Do you know how many qi skills are contained in it?" Xukong questioned.
"I don't… I just know that Sky Prop is the first but there are several more." Lin Mu answered. "And… I think I sensed something more during the Immortal Tribulation." He added.
"Dao Traces? It was a variant immortal Tribulation so that is likely." Xukong agreed.
"I just don't know what type of Dao Traces they were. I feel like I'll recognize them once I see them again." Lin Mu spoke.
