Mu Qingshan, a veterinarian, accidentally killed a Rottweiler after encountering a Rottweiler biting a little girl. As a result, extreme dog lovers attacked the dog online. Some even went to the pet hospital where he worked to cause trouble. Mu Qingshan was forced to resign and return to his hometown in the mountain village. When I went home to collect mushrooms in the mountains, I accidentally got a sign-in and clock-in system for mountain running. As long as I sign-in and clock in in the mountains, I can get various rewards. He gained the ability to be an animal friend on the first day, and from then on all the animals in the mountains became his friends. Treat the injured little jackal, get help from the jackals, and be escorted by the jackals every time you enter the mountain. There are no people deep in the mountains of matsutake, hericium, and gallinomycetes.
