For Lu Ren, there wasn't much resistance; eating people's food, doing people's business is a very simple truth. However, he would not really push forward aggressively. He was just a passerby in this world, and with less than two days left he could leave here. Why fight a life-and-death battle after all?
Loafing around is universal; just doing work without effort is fine.
Moreover, his arms are still injured. If something goes wrong, it might leave hidden ailments, affecting future improvements.
At least it's temporarily safe here.
After all, he isn't from this world; empathy capabilities really can't align with this place.
Lu Ren had eaten and supplemented with a highly concentrated nutrient pill, meditated on the Heartless Sword for a while, then lay on the bed fully clothed and fell asleep.
