Seeing Su Wen's disappointed expression, Mo Yi couldn't help frowning, and immediately suggested: "In my opinion, now that you haven't even skimmed the eight characters of your experiment, why don't you take a chicken and duck to try it first?" When the preparations are almost complete, it is not too late to use human blood. ”

Listening to his suggestion, Su Wen secretly rolled his eyes in his heart. She just wanted to look into the cross-matching test, and theoretically there was absolutely nothing wrong with it. In her opinion, as long as there are certain hardware conditions, this experiment is not difficult to do, and it is almost impossible to encounter any failure.

It's a pity that she can only complain secretly in her heart, but she doesn't dare to tell the truth. If she really said it, I don't know how many troubles would follow.

Although he was not very happy in his heart, Su Wen still accepted Mo Yi's suggestion. After all, her current technology is not mature, and she does need to do some animal testing. When the technology is mature, she can find another way to get some people's blood, and when the time comes, she will try to achieve success at one time.

Just do it, Su Wen immediately ordered someone to go back to Washington to find Yun Niang. She has been in charge of the kitchen in Washington during this time, and naturally there is a lot of chicken and duck blood to deal with every day.

After figuring out the source of the blood, Su Wen immediately worried about the test utensils. She wanted to have the same clear glassware as she had in her previous life, but it was clear that there were no such tall objects in this era. She struggled for a long time, not knowing if she should take advantage of the situation to make transparent glass?

After thinking about it, Su Wen still gave up this idea. Her wings are not yet full, and if she had hammered out the transparent glass early, it would definitely attract the attention of those who care, which was not what she wanted to see.

Although there were no clear glassware, Su Wen found a replacement. In this era, there were clear crystals, many of which were carved into vessels for holding liquids. Needless to say, there is such a thing in the Yongning Hou Mansion, but the price is relatively high, and it really costs a lot of silver.

If it weren't for the discount, Su Wen would not have spent money to buy it this time. Fortunately, the discount is not small. She gritted her teeth and bought it.

For Su Wen's behavior of having to buy, Mo Yi is very incomprehensible. In his opinion, these clear crystal vessels were just some goods, as long as he spoke. There is nothing wrong with giving it to Su for nothing. With him as the gold master, she has no need to waste An Hetang's silver.

I have to say that this is the generation gap of the times. Unless he travels back in time to the modern era, Mo Yi will never be able to understand Su Wen's proud self-esteem.

In Su Wen's view, if girls want to be treated equally, they must first be financially independent. There is no doubt that the first step to financial independence begins with the rejection of expensive gifts. She uses her own money for every expenditure, and only then will she have the confidence to fight for a greater voice in the relationship.

With the clear crystal vessel, Suwen's experiments can finally begin. She had done this experiment countless times in her previous life, so this time it was mainly to cultivate the hands-on ability of An Hetang's apprentices.

Before the trial. Suwen trained the apprentices of An Wo Tong. She carefully explained the theory of the cross-matching blood test, so that they had a relatively complete understanding. After she had tested their theories, she began to conduct the real experiments.

Since he already had a preliminary understanding, Su Wen saved the trouble of teaching by hand. She just needs to stare at the side, reminding her from time to time.

Let's be honest. According to Su Wen's original expectations, although they don't have those advanced modern equipment, it shouldn't be too difficult to do. Unexpectedly, the reality is even more cruel than she imagined. In the course of the experiment, they encountered many unexpected difficulties, and the first experiment ended in failure.

After summarizing the difficulties encountered, Su Wen ended the experiment. She needed to go back and groom herself. Aim to start a second cross-blood trial as soon as possible.

Knowing the results of the test, Mo Yi didn't forget it and said coldly: "Look, does my proposal seem very necessary?" Fortunately, this time it is chicken blood, and the key is to use human blood directly according to your wishes, I guess it is not so calm now, and those who donate blood will definitely make trouble. ”

Hear him say that. Su Wen had to admit: "It's still thoughtful, you really should try chicken and duck blood at the beginning." I took this for granted, thinking that if I had a way, I would definitely succeed, and it seemed that I would have to deal with it carefully in the future. ”

Seeing that her morale was a little low, Mo Yi hurriedly smiled and encouraged: "It's just a failure." You're not going to be knocked down so easily, are you? There is a saying that you said once, but I have always kept it in my heart, and it is the right time to give it to you. Failure is the mother of success, and I believe that there will always be a time when you will succeed. ”

Hearing the familiar declaration of determination in his previous life, Su Wen was touched a little in his heart. It was the first time she had heard someone encourage her in such a long time.

Smiling brightly at Mo Yi, Su Wen raised his head and said confidently: "Don't worry, I'm a Xiaoqiang who can't be killed, and I won't take a small failure to heart." As long as I pay attention to it, it will not take long to successfully complete this experiment. ”

Seeing her confident look, Mo Yi's eyes revealed appreciation. She likes Su Wen's confident look, and there is a charm that makes people want to keep getting closer.

The next day, after a night of combing, Su Wen finally found a solution to those difficulties. She didn't wait any longer, and on the same day she called her apprentices for the second round of trials. She came prepared this time, and many of the problems that happened for the first time were resolved in a timely manner.

After a period of operation, the results of the test are finally out. Through the observation of hemolytic reactions, she determined that two groups in this trial had achieved the ultimate success.

Despite this, Su Wen did not feel relaxed. She ran a total of eight experiments, and only two of them were successful, which is a bit low. She had to find a way to increase the success rate, or she didn't know when the blood transfusion would be possible. As for how to improve the success rate, we can only continue to explore it from practice.

Immediately afterward, Su Wen began the third round of trials. This time, she observed more carefully, recording every step in detail, and used dozens of drafts alone.

It must be mentioned that in order to improve the speed of writing and at the same time achieve the purpose of saving paper, Su Wen decisively abandoned the use of the brush, and instead learned from the Europeans to use the quill pen. She used it for a while and found that in terms of note-taking, a quill pen is more suitable, which is more in line with modern people's writing habits.

From this experiment, Suwen has summed up some experience. She carefully compared the differences between the two sets of trials and found some slight differences in details.

It is because of these nuances that the results of the experiment are different...... What is a mistake of a thousand miles, she finally understands it now. Fortunately, everything is in a hurry, and she can continue to improve and modify the steps of the experiment, and I believe that the success rate will be improved a lot.

After further refining the test steps, Suwen couldn't wait to start a new round of cross-matching tests. She wiped her eyes bright, staring at every revised detail.

Probably found the crux of the problem, and this round of trials achieved gratifying results. Although the success rate still did not reach 100 percent, six of the eight groups had already achieved the desired results. There may be some details that affect the success of the trial that have not been discovered, but can be slowly found in subsequent trials.

The success rate has been greatly improved, and Su Wen is not in a hurry to switch to human blood for experiments. She felt that this matter could not be rushed, so she needed to continue to do multiple tests to verify the results.

From this day on, the apprentices of Anhetang did half a month of cross-matching animal experiments. They were all full of freshness at first, but after half a month, the initial freshness has long been consumed. If it weren't for the strict requirements of the plain question, they might have slackened off a long time ago.

Through continuous observation for half a month, Su Wen is familiar with almost every step of the experiment. She scrutinized and compared, and finally found some factors that might affect the success rate.

With her meticulous analysis, the success rate of the experiment has been improved a bit. Now eight groups are running trials at the same time, which basically ensures that six or seven groups will be successful, and sometimes even eight groups will be successful. This is undoubtedly a big step forward compared to the previous one.

After getting the animal test done, Su Wen decided to take a break for a while and then start the human cross-match blood test. She thought about it, and the blood needed for the experiment was drawn from her and An Hetang's apprentices, saving all kinds of rights and wrongs from the outside.

At the very beginning of this incident, Suwen fell into the inertial thinking brought about by the research of his previous life, and excluded the researcher from the list of volunteers from the beginning. In their previous lives, they basically needed to recruit volunteers to do academic research, and rarely used their own people to do research, which would affect the accuracy of the research results.

This life is different, they do not have the same mature research system as in the previous life, and the recruitment of volunteers will be a very difficult problem, and may bring some unexpected social and ethical controversies.

For example, the cross-matching test they are doing now has a memory base from their past life, so they don't think there's anything wrong with it. People in this era are different, they have never been exposed to blood transfusions, so they do not know the significance of cross-matching blood tests. In their eyes, this experiment may be equivalent to the human cloning experiment in a previous life.

Recognizing this, Su Wen decided to take his time. She started to persuade from the people around her, believing that one day she would use facts to convince the world.
