Siheyuan: Promoted to engineer, torturing and weeping animals

[System + life system + don't lick the dog]
Zhang Yi traveled to a courtyard and became a nerd who died suddenly while preparing for an engineer exam.
Just after crossing over, I met many animal neighbors who came to divide the family property.
Zhang Yi, who knows the faces of these neighbors in the courtyard, directly angered all the animals!
Then start the sign-in system, as long as you sign in every day, you will get rewards!
Sign in advanced mechanical skills, become the top engineer, and be admired by others!
Sign in to a personal farm, and the output of one person's farming and animal husbandry is comparable to that of a large farm!
At this time, all the animal neighbors wanted to come over to take advantage, Zhang Yi sneered, don't mess with me, whoever messes with who!
