With the mountain descent imminent, Lu Xun became busy.
Uh… mainly busy in the kitchen.
He intended to marinate some food, prepare some bacon, and make some beef sauce, chili sauce, and the like.
Once he left the mountain, his third Junior Brother would undoubtedly persist in "feeding excrement" to everyone. Lu Xun was doing all of this to allow them to eat something normal while enduring the "eating of excrement".
By then, even if he wasn't on the mountain, his two Senior Sisters and Mister would still bless him during meals.
Perfection!
While Lu Xun was making these things, his third Junior Brother was always watching by the side.
Who made Lu Xun initially consider the feelings of the third Junior Brother and blatantly claim in front of everyone: "The reason I thought of making these things is thanks to exchanging cooking skills with the third Junior Brother on usual days, he inspired me."
