Siheyuan: I was secretly replaced by Yi Zhonghai on the promotion list

[This book has hostility, don't enter if you don't like it, abuse animals, don't lick dogs. 】
After Chen Yu traveled over, he found that the original owner had been slapped to death by Jia Dongxu.
Not only that, but the only relative was my sister who was suffering from stomach cancer and urgently needed money to buy medicine.
From memory, I learned that the original owner had survived enough years of service and could finally be promoted to a first-level fitter.
But in the final assessment list, his name was replaced by Jia Dongxu.
The angry original owner asked Jia Dongxu for a theory, but was beaten to death by Jia Dongxu.
This is a murderous revenge, how can Chen Yu, who has traveled through time, not avenge it?
Yi Zhonghai: "Chen Yu, didn't you just bleed a little?
Is it okay to be alive and kicking? "
Qin Huairu: "Chen Yu, my Dongxu is just joking with you, why do you take it seriously?"
Jia Zhang: "Your Chen family is dead, and the house belongs to my Jia family!"
Deaf old lady: "Chen family boy, do you believe that I crashed and died at your door?!"
Silly Zhu: "Chen Yu, why do you disrespect the old and love the young?
What if you let the old lady hit you once? "
Facing the yard full of beasts, Chen Yu was never used to it.
The revenge of murder must be repaid a hundredfold!
