Su Wan shook his head and said with certainty: "He is not my master. You don't need to see him specifically. If you have the chance to see him, you will see him. If you can't see him, you will disappear."

Old Hua looked at her suspiciously.

Her medical skills are obviously in line with that person. Even if she is not a master-apprentice relationship, she should have a master-education relationship.

But this girl was a little excited when she first heard about it, and was very calm behind her.

However, Su Wan did not plan to continue this topic. Mr. Hua, who has long been indifferent to human affairs and is not careful about details, naturally could not make more trouble.

Seeing that Su Wan was about to leave after asking, he quickly called Su Wan, "Hey, girl, don't hurry to leave. You haven't told the old man what he did when he was drawn out!"

"Is blood exchange?" Old Hua looked at the blood in the blood collection duct on his own and said in confusion: "But such a little blood is not enough to change! Besides, the boy named Peng was infected with the wind and cold and became angry again, which caused the cold to attack the heart, which made him feel high fever.

It’s not poisoning, there’s no need to change blood at all!”

Su Wan looked at Hua as he was old and looked humble and studious, and smiled and said, "Master, this little blood is naturally not used for blood exchange. Do you know that wind and cold are also divided into many types. I took Brother Peng's blood and could use another instrument to see what's in his blood.

Find out what caused him to get cold."

Su Wan tried to explain to Mr. Hua as easily as possible the difference between bacterial infection and viral infection.

But after all, there is a thousand years of knowledge barrier between the two. No matter how simple Su Wan said it, Mr. Hua was still confused.

He frowned and thought, while asking Su Wan, "Girl, do you mean that there are many small bugs that we cannot see in our eyes in this world. Different types of small bugs will also cause different types of wind and cold when entering our bodies?"

"Well, that's what it means!" Su Wan nodded, feeling that Mr. Hua didn't have much trouble understanding bacteria and viruses as invisible bugs.

At this time, Old Hua looked at Su Wan with a eager look and rubbed his hands with a little excitement, "That... girl, let's discuss something..."

"no."

Before Mr. Hua finished speaking, Su Wan refused with a stern face and said righteously, "Master, it's not that I don't show it to you, but I really can't show it to you."

As soon as Mr. Hua spoke, Su Wan understood that the old man wanted to discuss with her and let him try to detect bacteria and viruses in the blood.

It’s really not that Su Wanxin was not as good as Mr. Hua and was unwilling to do it for him, but that she was really powerless.

She has tried it. Only small ones that can be taken out by one hand can be taken out, while large ones cannot be taken out at all.

And even if it is taken out, there is no power supply outside, and those instruments cannot be used.

Mr. Hua pursed his mouth like a child, looking dejected as if he was wronged, "Okay..."

After Su Wan returned to the room, he entered the space and took Peng Bin's blood for testing. The test results showed that it was an ordinary virus infection.

Su Wan breathed a sigh of relief. When she saw Peng Bin's tongue being scarlet, she was still worried. If there was another highly contagious bacteria or virus, it would be another trouble.

Su Wan came out of the space, walked out of the room, and was about to go and see Peng Bin's situation again, and saw Xiao Jing'er sitting at the door of her room with a serious face.
