"Auntie, what's the matter?" Qin Lang grabbed the woman and asked. Obviously, the woman didn't come out of her anger just now. She said angrily, "this clinic says they have serum. It turns out that they sell 50000 yuan for a single injection. What's the point of robbing money?"

Fifty thousand?

Qin Lang was secretly surprised.

He had a hunch that something was wrong, and then the woman left with her children, and everyone began to talk about it.

"This person is really, say is serum also don't know true false, if buy back is false, lose money is a small matter, don't take life in."

"No, well, try it."

"I know they are making money, but what can they do?"

......

Qin Lang and Bai Yin listen to the public's comments. Their brows are tightly knit. They are not ordinary people. Naturally, their eyes and opinions are not understood by these ordinary people.

"Qin Lang, I feel it's tricky." Said Bain.

Qin Lang nodded: "no matter what, buy one and take it back to Dr. Tang for testing. Everything will be clear."

Qin Lang and Bai Yin didn't turn until midnight.

Qin Lang just saw the man's appearance. He is a standard Yanguo man with short hair in his forties.

Qin Lang bent over the counter and took out a pile of thick banknotes: "I'll buy twenty."

"Twenty?" The man was shocked and raised his head. He smiles at the corner of his mouth. It seems that he has met a big client this time: "do you have enough money?"

Qin Lang pointed to the money on it, but the man looked at the bill and gave a cold smile: "sorry, the price has gone up now. One bill costs 100000."

"100000?" "You're starting from the ground!" he exclaimed

The man is not afraid: "I just sit on the ground, what can you do?"

Bai Yin was very angry: "what if your serum is fake?"

"Fake? If you doubt it, you can not buy it. Most people want to buy it. "

The crowd immediately roared after him.

"That's right. If you don't buy it, don't occupy the position. Get out of the way."

"If you don't buy it, there are still people who want to buy it. Don't delay."

......

Qin Lang looked at the crowd behind him, then took out a pile of money, and baiyington took his arm: "are you crazy?"

Qin Lang just shook his head at him.

Then, the man happily put a pile of money package down, after counting, a total of two million.

The corner of the man's mouth was full of laughter. He took out two suitcases and put them on the table. Qin Lang took the suitcases and squatted on the side of the road to check them.

Poof.

There was a chill when the suitcase was opened. There were ten small glass bottles and ten syringes in the suitcase. The total of the two suitcases was just 20.

This is the serum?

"Qin Lang, they are obviously deceiving. How can you believe it?" Baiyin was helpless.

Qin Lang closed his suitcase and left: "whether it's true or not, I'll have a try."

Later, they came to the hospital with the medicine. He gave a serum to Dr. Tang and asked him to take it for test.

Qin Lang was waiting in the office. Half an hour later, Dr. Tang came back. He was overjoyed with a report: "Mr. Qin, where did the serum come from?"

"After testing, the serum can indeed treat the mixed snake venom, but the mixed snake venom is very complex. Even if it is necessary to develop the serum, it will take at least several months or even half a year!"

"Really?" Qin Lang was relieved at last, and then he asked, "does this serum have any side effects or other hazards?"

Dr. Tang looked very excited.

He has tested that this kind of serum can indeed dissolve the mixed snake venom, and the side effects and hazards have not been found for the time being, but there should be no problem.

"Mr. Qin, where did the serum come from?"

Qin Lang told Dr. Tang what had happened. After hearing this, it seemed very inconceivable. Experts from major hospitals in Kowloon Bay studied it for several days, but they didn't even know the ingredients of snake venom. A street clinic actually had serum?

It's too weird.

"Whatever it is, it works." Doctor Tang doesn't have the heart to manage these now. He takes the serum and looks at Qin Lang: "Mr. Qin, I need to remind you that the origin of the serum is unknown. If you want to fight or not, I will listen to you."

Qin Lang looks at the potion and is lost in thought.He couldn't pay attention to this medicine for a moment, but Yan Shuya was in danger and needed serum urgently.

Qin Lang rolled up his sleeves and said, "give me an injection first. If there is no danger, give Shuya another injection."

"Qin Lang, you are crazy!" Bai yindang stopped in front of Qin Lang: "it's too dangerous, I don't agree!"

Before he came to Jiulong Bay, Bai Yan told Bai Yin that Qin Lang had a special identity, so he must not be surprised.

After all, on his shoulders is the whole Yan Kingdom and Yan Huang guard.

"Bain, I have no time now." Qin Lang shakes her head and pushes away Bai Yin. Bai Yin falters for a while and then stabilizes herself. She goes over and grabs a syringe from Doctor Tang and sticks it in her hand: "Qin Lang, your identity is special. I'll try the medicine for you."

"Baiyin, why are you doing this?" Qin Lang was helpless.

Baiyin said, "grandfather said that even if we all die, you can't die."

"Besides, it's just serum. It's OK." Baiyin smiles and injects himself.

Later, Dr. Tang observed Baiyin and took Baiyin's blood for test. The test results showed that the serum was not harmful to Baiyin's body.

Qin Lang was relieved.

Then Qin Lang asked Doctor Tang to inject Yan Shuya.

Qin Lang also left a piece of medicine to Dr. Tang for him to study and try to copy Xuexue Qing as soon as possible.

In the evening, Qin Lang is alone on Yan Shuya's bed. The next day, Qin Lang is awakened by a agitation. He lies on Yan Shuya's bed and slowly raises his hair. Now Yan Shuya is awake.

"Shuya, how are you feeling now?" Qin Lang immediately asked, Yan Shuya felt: "I feel very good, where did you get the serum?"

Qin Lang was relieved to hear that.

Last night, he asked Dr. Tang to inject serum into Yan Shuya. When he woke up the next day, Yan Shuya's face was much better and her lips were bloody. It was obvious that the serum had an effect.

"Does the street clinic have serum?" Yan Shuya was surprised after hearing this. Qin Lang quickly explained to her not to be afraid: "Dr. Tang has checked the serum. There is no problem at all. You can rest assured."

"But how could a street clinic have serum? This kind of serum mixed with snake venom is not so easy to develop." Yan Shuya then asked, "it's easy to get a single kind of snake venom serum, but this kind of venom is mixed with snake venom. It's too strange."

Qin Lang nodded. That's the problem.

So he decided to make a good investigation. Now that Yan Shuya is stable, he can feel better and find time to investigate this matter.

"Shuya, I bought you breakfast. You can have some." Baiyin and Jiang Yang push the door of the ward and come in.

Yan Shuya is OK, and they are all injected with serum, which can be regarded as a guarantee.

Yan Shuya hasn't had a good meal these days. He has been hungry for a long time. Qin Lang and his party stand by the bed and look at each other. Qin Lang takes everyone out.
