Chapter 1639: Untitled

She told Little Spirit about the things that she needed to use, and Little Spirit immediately prepared those things for her.

He didn't leave while Sima You Yue examined those things. When he saw that powder that she had taken out, he asked, "This powder can be used to open a barrier?"

"Those people dust this powder on them when they enter. I'm guessing that this is the key to opening the barrier." Sima You Yue said, "At that time, the Yang Clan used Death Aura as the way to open it. These people use powder, so it should be correct. I just need to examine what it's made off, then Master and the others will be able to exit the barrier."

Little Spirit didn't speak anymore and accompanied her in the refining room for a few tens of days. Once she came out, she had already produced a lot more of the powder.
