After taking the blood of the two people, Jiang Erlang also came back from next door, accompanied by Doctor Qiao.

Doctor Qiao was in the next room listening to the noise outside and became more and more worried. Finally, he couldn't suppress his curiosity and followed Jiang Erlang.

As soon as he entered the room, he saw Jiang Huaixu sitting at a table not far from the door, concentrating on something. There were some strange jars on the table, and behind her was a drawn curtain. He didn't know what was behind it.

Jiang Erlang said hello and went behind the curtain.

"Second brother, I have two samples of blood I just took, labeled with names. Please test them both and mark A, B, and C."

After hearing Jiang Erlang's response, Jiang Huaixu looked at Doctor Qiao who was checking the blood collection jar.

"Dr. Qiao, what are you looking at?"

Doctor Qiao pointed at a yellow tube he had never seen before and frowned as he asked, "What is this?"

"It's made from something grown by a tree in the far south. I found it by chance and thought it could be used for blood transfusions, so I used it."

“······” Doctor Qiao felt that he had never been so ignorant. How come he had never heard of what Jiang Huaixu knew?

"Is this needle hollow?"

"Yes, as long as the needle is inserted into the blood vessel, the blood will flow through the needle hole into the blood container."

After marveling at the fineness of the needle, Doctor Qiao leaned over to look behind Jiang Huaixu and asked, "A blood test—may I take a look?"

At this time, footsteps were heard outside again. Jiang Huaixu hurriedly said, "Doctor Qiao, please stop making trouble here and go back to take care of Mr. Fang."

The curiosity on Doctor Qiao's face disappeared in an instant. He snorted and muttered, "How stingy."

He left with his hands behind his back.

The people who came in were Wan, Yang Zheng and Dong Feng.

The rest of the people had their blood drawn and tested quickly. When all the results came out, Jiang Huaixu looked at the blood types his second brother had written down - Fang Zhan was C, Aunt Xia was A, but Fang Bin was B.

In order to prevent any mistakes, Jiang Huaixu also looked at the blood test results of the three people, which were consistent with the results recorded by Jiang Erlang.

If Fang Bin is the child of Fang Zhan and Aunt Xia, then his blood type can only be A or C. This result...Mrs. Fang won the bet.

Thinking this in his heart, Jiang Huaixu couldn't help but say the last sentence.

"What bet did you win?" Jiang Erlang asked.

Jiang Huaixu smiled and said, "Second brother, I won't tell you yet. It won't be too late to tell you after this matter is exposed."

Jiang Huaixu was reluctant to speak, and Jiang Erlang didn't want to force him, so he just continued to ask, "Can I draw blood now?"

"Yes, come one by one, and only call those with blood type B."

Jiang Erlang nodded, took the paper handed to him by Jiang Huaixu, opened the door, and called the first name - "Yang Zheng!"

"Fang Bin and I share the same blood?" Yang Zheng asked impatiently as he entered the room. "No wonder we are relatives!"

Jiang Huaixu looked at him as if he were a fool, and all her words just now were in vain.

"There are thousands and thousands of people with the same blood type as you in the world. Are they all your relatives?" Jiang Huaixu said with a fierce look on his face, "Sit down and don't move. If the needle goes astray, you'll be the one who gets hurt."

Yang Zheng immediately stopped moving, still muttering, "Does Dong Feng have the same blood as me? And Bai Erlang, he must not be like me..."

"I'm afraid I can't do what you wish. Bai Jilang is a B just like you."

Yang Zheng looked as if he had been struck by lightning. Jiang Huaixu took advantage of his dazed look to insert the needle into his vein. The blood gradually flowed into the porcelain jar through the rubber tube.

"Ahhhhh——" Yang Zheng was awakened by the stab, and saw the blood in the jar and screamed like a pig being slaughtered. He wanted to shake off and leave, but he couldn't break free.

Jiang Huaixu frowned, "The more you struggle, the more it will hurt."

The sound gradually faded, and Yang Zheng squeezed his eyes shut. "Why aren't you healed yet? Are you going to drain all my blood?"

Only after the blood filled the blood collection jar did Jiang Huaixu pull out the needle and let Yang Zheng leave.

Seeing Yang Zheng staggering as he left, as if he couldn't bear it anymore, she called out to him, "Second Brother," and asked, "Tell the person who comes in later to blindfold themselves!"

Jiang Erlang's smiling voice came from the door, "Okay."

Jiang Huaixu took the freshly collected blood and went to the next room. He drove everyone out of the room, lowered the curtain in front of the bed, fiddled around inside for a while, came out, and returned to the blood collection room to collect blood from the next person.

After the person was blindfolded, the speed of blood collection increased.

Modern people's blood transfusions are all processed, but she didn't have that condition, so she could only transfuse it directly. While collecting blood, transfusing blood, and constantly monitoring the patient's condition, Jiang Huaixu was so busy that he sweated profusely.

After the blood transfusion was almost sufficient, she put away all her things and walked over to Doctor Qiao, who had been waiting outside the door. "Doctor Qiao, could you please feel Mr. Fang's pulse and see if he feels better?"

Doctor Qiao had been waiting anxiously for this sentence. As soon as Jiang Huaixu finished speaking, he trotted into the house to check the situation.

When he came out of the house again, he nodded in confirmation in response to everyone's questions, "The situation is better now, but we still need to observe for a few days."

Fang Zhan and Aunt Xia breathed a sigh of relief at the same time, and Wan Shi also relaxed a little imperceptibly. Remembering something, she looked at Jiang Huaixu, who happened to be looking at her at that moment.

An idea struck her, and she stepped forward and said, "Thank you so much, Doctor Jiang! You not only saved Zheng'er, but also Bin'er this time. I'm so grateful. I brought a hundred-year-old ginseng with me when I came here. I originally wanted to keep someone alive in case of any problems, but now it's useless, so why not give it to Doctor Jiang? Doctor Jiang, why don't you come with me to take a look?"

Jiang Huaixu humbly declined twice, but in the end he couldn't resist Mrs. Fang's "enthusiasm" and followed her.

When she reached the carriage and saw that no one was around, she whispered to Madam Fang, "Madam Fang, let me cut to the chase. There are three common blood types, which I call A, B, and C. Master Fang's blood type is A, and Aunt Xia's is C. Any child born to them could only be A or C, but Fang Bin's is B. This confirms that Fang Bin is not Master Fang's biological son."

Mrs. Fang had some guesses in her mind, but after hearing Jiang Huaixu's words in person, she suddenly felt dizzy. When she was about to lose her balance, she was supported by a pair of small hands. After pausing for a while to recover, Mrs. Fang forced a smile and said, "Excuse me, Doctor Jiang. I will tell the master about this matter. Whether he believes it or not is not up to me."

Jiang Huaixu nodded. Having been childless for many years, Mrs. Fang's title of Madam was probably criticized by many people. Today, it can be seen that her relationship with Fang Zhan is not as harmonious as the rumors say.

After all, every family has its own problems.
