While Shen Min gradually came back to reality, Wu Long collected the Yin Qi into a small bottle with a formation carved into it. He once used this bottle with Sui Luxiao at the banquet. This was not an ideal method, as the Yin Qi would drop in quality over time even with various preservation formations carved in addition to the gathering formation. The main reason was that the formations were of too low quality. But he did not need to preserve it for a long time, as he could cultivate it this night, and the main reason for using the bottle in the first place was not for gathering but erasing evidence.
