He was a disabled military officer who doted on his research work in the Northwest.

In her previous life, Shen Tang was an agronomy PhD and a successor of traditional Chinese medicine. When she opened her eyes one day, she found herself to be the real daughter who had been sold off by her own father in the 1970s.
The adopted sister was unwilling to marry a disabled military officer, so her biological father pushed her out to marry in her place.
Everyone says that the Mu family member is crippled in both legs, will die soon, and will have no descendants.
Shen Tang glanced at the priceless jade bracelet and smiled: "I'll marry you."
After signing the letter severing ties with her family, she dusted herself off and went into the military compound.
Everyone was waiting to see the joke.
Then--
Vegetables were grown on the saline-alkali land. Shrimp were raised in the abandoned saltwater ponds. The entire military region was able to eat high-protein food.
The disabled leader's leg has healed.
The problem of having no heir has also been cured.
The once aloof and cold-faced leader gradually fell for her, turning into a jealous vortex and chasing after her relentlessly.
She would chat with her tutor a few more times about academics, and he would volunteer to be her tutor; when someone tried to set her up with a marriage proposal, he would immediately turn hostile and snatch the girl away.
Her adopted sister laughed at her for marrying a good-for-nothing? Turns out, the good-for-nothing who was married in her place became the youngest general in the capital.
Her biological father regrets his decision and wants to acknowledge her back? She's already a top student at Tsinghua University, studying under a leading scholar in the country.
Shen Tang stood on the podium of the National Science and Technology Competition, with the man who once sat in a wheelchair behind her.
He leaned on his cane, his gaze as gentle as melted ice.
"Shen Tang."
"Um?"
"You said it wasn't about the bracelet."
"No, it isn't."
"Okay. No."
He smiled.
—That was for me.
