In Ancient Times, I Became Stronger by Inhaling the Ginseng Fruit.

The otaku Yuan He was reborn as a ginseng fruit tree in Wuzhuang Temple on Wanshou Mountain. After awakening the "prehistoric scavenger system", you can become stronger as long as you absorb harmful gases (evil gas, karma, poisonous smoke, and even boss's farts). On the day of his transformation, he sucked up all the innate evil energy within a radius of thousands of miles, and even Zhen Yuanzi was stunned.
