"Tunan, this is not the place to talk. Let's go home and talk slowly."

The snow grew heavier, covering all traces of the fight. Between heaven and earth, there was a blanket of ice and snow.

The car wasn't that cold, but it wasn't warm, and I was afraid the snow was too thick and it would be unsafe to drive back.

"Okay." Sheng Tunan took the steering wheel, shifted the gears, released the handbrake, stepped on the accelerator, turned the car and drove towards the military compound.

It was snowing heavily late at night, and Sheng Tunan didn't dare to drive too fast, and it took him more than twenty minutes to reach his home.

Sheng Tunan had just parked the car when he saw Shen Peifeng running towards him with his head covered in snow. He called out "Brother, sister-in-law," while looking towards the back seat of the car.

Shen Peifeng breathed a sigh of relief when he saw Shen Zhixian return safely.

"How come you are here so late?" Zhan Xinyue saw Shen Peifeng and Bai Yunyun holding an umbrella and asked as the five people in the car got out of the car.

"It was past nine o'clock, and the fourth brother hadn't returned home yet, so I went out to look for him." After they entered the house, Shen Peifeng gently brushed off the snow on his head.

"The guard told me that the fourth brother and the eldest brother went out, so I came here to wait."

Zhan Xinyue nodded and looked at Bai Yunyun who was collecting an umbrella. Just as she was about to ask her what happened, Sheng Tunan spoke first, "Peifeng, you and Yunyun are still together so late, is something good coming?"

"No, Yunyun came to see my sister-in-law for something urgent and we just happened to meet." Shen Peifeng explained.

"Oh, what's the hurry?" Zhan Xinyue sat on the sofa, took a sip of the hot milk that Sheng Tunan brought over, and asked after warming up her body.

Bai Yunyun was already sitting on the sofa, and Shen Zhixian followed Sheng Tunan to the kitchen to make milk for her and her sister. Shen Peifeng sat on the sofa and wiped his glasses that were wet by the wind and snow.

"Sister-in-law, some time ago, you asked me to study patients with uremia and try to make a breakthrough in DNA technology to develop a specific drug to treat uremia." Bai Yunyun followed Shen Peifeng and called Zhan Xinyue sister-in-law and explained the purpose of their visit today.

After hearing about the special medicine for uremia, the sisters Hong Xing and Hong Chen held the hot milk that Shen Zhixian had just handed over and listened attentively.

"By studying the genes of patients with uremia, I have come to the conclusion that patients with uremia have already suffered irreversible damage and abnormal kidney function. As a result, the kidneys cannot eliminate toxins and excess water in the human body. Only hemodialysis or kidney transplantation can save lives. Uremia cannot be cured by drugs at all." Bai Yunyun stated the results clearly.

The sisters Hong Xing and Hong Chen looked uglier the more they listened.

Hong Xing went from hope to despair. After hearing the last part, Hong Chen looked at her twin sister and nodded with determination. If there was no specific medicine, she would donate a kidney to her sister.

The two sisters were born in a certain year and month, and will die in a certain year and month.

"Sister-in-law, I think we should no longer waste manpower, financial resources and time to develop drugs to treat uremia. Because this disease is irreversible, there is no other way except organ transplantation and hemodialysis." Bai Yunyun added.

In the 1970s, only a few large hospitals in China provided hemodialysis. Hong Xing looked at Shen Zhiyan with despair, knowing that this life was not meant for him and her.

"Pei Feng," Zhan Xinyue did not answer Bai Yunyun's words, but turned to the second brother and said, "It's almost midnight, and it's snowing. It's too unsafe for Yunyun to go back to Zhongsheng Pharmaceutical. You send her out and ask the guard at the door to take her to a guesthouse that is specially for receiving family members to spend the night."

"Okay." Shen Peifeng nodded and took Bai Yunyun out. He wanted to talk to Bai Yunyun alone tonight.
