B city is a huge iron city. A restaurant owner Zhang lives in a remote corner of the city. He’s been here for three years, but nothing exciting happened. Yes, he got a system, but it seems useless. The tasks he got were easy, like walking the dog, growing vegetables, cleaning the house, etc. And the credit he got from the task was of no use. So what’s the meaning of his coming to this mist world? Days passed by. He did not notice that his vegetables had turned into spiritual herbs while his dog turned out to be the Qilin Saint. So his credit is not the system but his dog?
