Gu Zhinong's eyebrow was picked. He turned and took out the blood collection needle from the drawer. "This is an anticoagulant tube. It's good to collect half a bottle of blood and send it to me within 24 hours. After 24 hours, the results are not allowed. After all, it's not an ordinary blood routine. It's necessary to obtain all a person's physical conditions through these blood. Even if I'm a doctor, it's difficult."

After receiving the bag and tube containing the blood collection needle, Su Xiaoxiao had a confused mind, "I... I can't prick it."

As soon as Gu's eyes closed, he took out an arm model from the next room and put it on the table, "relax and try again."

With that, he took out the blood sampling needle from the drawer, tore the package and handed it to her.

Su smiled and stared at the thin needle for a few seconds. She swallowed her saliva and reached out to take it.

She went to the table, Gu Zhi pressed the false arm for her, and said with guidance, "when inserting the needle, it should be inclined, and there should be a dark thrust. If it is unobstructed, it is in the right position. If it is blocked, don't tie it hard."

She listened carefully.

"Try?" Gu Zhi looked at her.

Su Xiaoxiao hesitated.

Gu Zhi took the needle from her hand as a demonstration, "watch me prick it once. Take the needle like this. It's easier for you to take it like this."

She took it very seriously.

Needle pricking is a piece of cake for Gu Zhi. After the needle is pushed in, bright red liquid flows into the pipe.

He said, "then insert the needle and flow half a bottle. Taking too much is also a waste. You should pay attention to safety when taking blood for him. Don't let your hands touch the blood. After collection, disinfect your hands. After all, he is a patient, and he may carry a lot of bacteria."

"OK, I'll pay attention."

Gu Zhi pulled out the needle and handed it to her, "try it again."

Su Xiaoxiao took the needle and stared at the position of the blood vessel. She learned to take care of her posture and strength and easily plunged into it. She was relieved to see the bright red liquid flowing into the jar.

"Genius."

"If being able to needle is genius, there are too many geniuses in the world." Su smiled with relief. She was very happy. "Thank you, doctor Gu."

"You're welcome, accomplice." Gu looked at her and opened her thin lips, "in fact, I have a strong desire to explore like you."

Su Xiaoxiao put Gu Zhi's blood collection needle and anticoagulant tube into her bag, "I'll come out to find you as soon as I get it."

"Be careful." There was a soft look in his eyes at her.

The tone of voice and eyes made Su Xiaoxiao slightly stunned. She looked at him, "well, don't tell him about it first. Because we have no evidence to prove all this, grandpa is old. I hope he can be calm in his old age. If he knows this, he will be very sad. "

"OK." Gu said, "I will develop an antidote for you as soon as possible."

"Thank you."

Gu's lips were lightly hooked, "you're welcome."

"Well, I'll go first." Su Xiaoxiao didn't have much time to delay. She had to go back to lunch because Grandpa would wait for her.

She walked out of the infirmary, did not go to the president's office, and quickly walked through the corridor towards the president's exclusive elevator.

Just about to print the fingerprint, the door opened.

Xia Fei saw her with a bright smile on her face. "Smile, why are you here?"

"I..." her head could not turn a little. "I'm looking for a high reputation."

"Did you find it?" Xia Fei walked out of the elevator. "He was in the office this morning."
