Plant Yin and Become an Immortal

The protagonist Zhong Yingxian was originally an outstanding-looking social worker on Earth. On his way to get off work, he accidentally picked up a seed covered in black gas. The moment Zhong Yingxian picked it up and looked at it, he seemed to be forcibly dragged by something and came to a strange place. Zhong Yingxian was dumbfounded and explained everything around him. The people here were dressed in clothes that looked like those from the Han and Tang Dynasties, and they were speaking Chinese that seemed to be from a hundred or two hundred years ago. The passers-by were shouting something like wishing someone to become an immortal soon. ? Become an immortal soon? Cultivation? ! !
