During the Dajing Dynasty, there was a mountain called Wanggui Mountain on the border. The mountain contained a "spiritual vein" that could grant wishes but shorten one's life.
Shen Qingci, a cynical Sanxian who just wanted to hang out and wait for death, was ordered to guard the spiritual veins, but his life was miserable and unreliable.
Xie Linyuan, a cold-faced and taciturn proton general who bore the hatred of his country and his family, forcibly broke into the mountains to make a wish to save his people.
The two went from being happy enemies who were fighting each other and cheating on each other, to gradually becoming sincere.
