After separating from Wu Xiaofei, Hu Wei, and Sun Beibei, Ye Chenfeng headed straight back to the valley in the Primeval Forest. The Yun Teng Mushrooms covering the ground couldn't possibly be transported out all at once, so Ye Chenfeng planned to first leave the Primeval Forest to help Tie Niu's father, Wang Youli, expel the deadly poison from his body, and then return to the valley to focus on improving his strength in peace.
The miasma in the valley wasn't going to dissipate overnight. Ye Chenfeng could barely resist the miasma by using his Soul Force, so he wasn't worried that someone would enter the valley after he left.
Besides, even if someone did come in, so what? Most likely they would mistake the Yun Teng Mushrooms for poisonous mushrooms. Not to mention harvesting them, they probably wouldn't even dare to touch them.
