"I'll show you to my lab." After leaving the coffee shop, he Jiayi said to Shen Zhiyu.
They took a bus to the research room of he Jiayi in shuoguo.
Open the door of the research room, you can see all kinds of chemical and medical equipment, which are placed in the table or closet. The glass tube is filled with special liquid, which is frozen.
Shen Zhiyu looks around. He Jiayi opens the drawer, takes out a thick needle tube from inside and walks to Shen Zhiyu.
"Do you know what this is?"
Shen Zhiyu turned his head and saw that he Jiayi's needle tube was two or three times thicker than the ordinary needle tube. It looked scary.
He Jiayi said: "if you want to study your blood, ordinary needles are not good. You must use this needle to extract your blood. Are you afraid?"
As if to frighten Shen Yu, he shook the needle.
But Shen Yu didn't even blink.
Seeing that he didn't respond, he Jiayi went on to say, "besides, your bone marrow will be extracted. The process is very painful and it will do great harm to your body."
Shen Zhiyu holds he Jiayi's hand and looks at him with deep eyes. His tone is unprecedented determination: "I know what you mean. It doesn't matter. No matter how painful it is, I will support it. No matter what it is, it won't change my decision today."
He thought that no matter how painful it was, there would be no pain in Xia Beiqing's legs when he was suddenly interrupted, nor the pain in Xia Beiqing's hot oil.
"Encounter, you..." he Jiayi's face was angry, especially wanted to curse.
He thought Shen Zhiyu was really crazy.
Shen Zhiyu saw through he Jiayi's idea and bent his lips: "you can scold me, as long as you are willing to help me." 
"All right." He Jiayi nodded, grabbed Shen Zhiyu's arm and put the needle tube close to him: "I'll try a little first!"
Shen Zhiyu didn't object. He took the initiative to roll up his sleeves to show his fair skin.
He Jiayi points the thick needle at Shen Zhiyu's blood vessel. The moment the needle pierces the skin, a sharp pain spreads all over the body and goes deep into the bone marrow. Shen Zhiyu suddenly clenches his fist, and his face fades all the blood color, and almost fails to stand firm.
It's a long time to draw blood. Shen Zhiyu clenches his teeth. When it's over, big sweat drops ooze from his forehead. His body shakes twice, as if he would fall over at any time.
He Jiayi observed Shen Zhiyu's face and asked, "how's it going? Will it hold up? "
Shen Zhiyu shook his head feebly, his voice was hoarse: "it's ok..."
He Jiayi originally wanted to scare back Shen Zhiyu with pain, but she didn't expect to hear Shen Zhiyu say it was OK.
How could it be all right!
He almost forgot that Shen Zhiyu was stubborn.
Since the blood has been pumped, he Jiayi has no choice but to sigh and shake the glass tube with blood in her hand: "I'll try it."
Shen Zhiyu took up his hand and grasped he Jiayi firmly: "thank you..."
The place where the blood was drawn was green and swollen, and the whole arm was stinging. He could hardly move. When he got home and opened the door, he saw Xia Beiqing sitting in the living room, and Shen Zhiyu was about to cover his arm behind his back.
Xia Beiqing picked up the pen and paper on his knee, wrote on it, and then held it up to Shen Zhiyu.
——Mr. Shen, did you go to see he Jiayi?
Shen Zhiyu pulled up his pale lips and nodded: "I'm going to see him."
Xia Beiqing stared at Shen Zhiyu's face for a while, then wrote on the paper.
——Mr. Shen, what's the matter with you? He looks very pale.
