"Yin and Yang, Positive and Negative, Heaven and Earth, Male and Female ......"

“…… From a macro point of view, our world is a balance of yin and yang, from a local point of view, but there is an imbalance everywhere, it is precisely because of the imbalance, there will be changes and development, and then there will be the world of flowers in front of us, if it is balanced everywhere, then the world will fall into an absolute static state, in that case, it is terrible......"

Xiao Yuan closed a thread-bound book in his hand, stared at the big words "Tai Chi Yin and Yang Derivation Theory" on the blue cover, carefully chewed some of the words he summarized from the book, and then looked at the watch on the wall of the laboratory, it was time to make an appointment with Xia Jiuying, and it was time to leave.

So he put the book in his bag, packed it briefly, said hello to his colleagues in the laboratory, and left the laboratory and went to the business school to find Xia Jiuying.

Riding a bicycle, bathed in the afterglow of the sunset, Xiao Yuan enjoyed this kind of time on campus, this is the third day of his return to Berkeley, although it is only three days, the huge environmental contrast makes him feel that the blood and death that happened before seem to have happened in the last century, every time he thinks about it, he will feel some unreal, and it also makes him cherish the time in front of him even more.

Coming to the outside of the business school campus, Xiao Yuan saw that Xia Jiuying was already waiting for him, today Xia Jiuying was wearing a pink jacket and blue jeans, standing there slim, forming a beautiful silhouette in the golden sunset, so that many passers-by couldn't help but want to take a few more looks.

When Xiao Yuan came forward, Xia Jiuying quickly found him, and also walked over to him, and when he came to his side, he skillfully sat on the back seat of the bicycle.

"Sit down, let's go." Xiao Yuan admonished, then pedaled the bicycle hard, left the business school under the envious eyes of many students, and headed in the direction of the Berkeley gene laboratory, after returning from San Francisco, he and Xia Jiuying both did an examination in the gene laboratory, and it was time to go to get the results this afternoon.

When they arrived at the gene laboratory, Xia Jiuying and Xiao Yuan reported their names, and then they were invited into a room by a doctor, apparently to give them a special explanation.

"Doctor, is there anything wrong with our body?" Xiao Yuan asked.

"A substance has been found in Natsu's body, and what exactly this substance is needs to be further examined." The doctor waved his hand, signaling Xiao Yuan to be calm for a while, and then talked about Xia Jiuying's situation first.

"Will this substance do her any harm?" Xiao Yuan couldn't help but be a little worried, and hurriedly asked.

"Because we haven't figured out what exactly this substance is, whether it will cause harm to her, or what kind of effect it will have on her body, needs to be further examined before we can finally draw a conclusion." The doctor said.

"So I need another blood draw for further testing?" Xia Jiuying asked.

"Yes, I'm afraid so." The doctor said.

"So is there something wrong with Xiao Yuan's blood?" Xia Jiuying asked.

"His blood exhibited strange characteristics, showing extreme resistance to drugs, and it was impossible to analyze his blood with ordinary analysis methods in the laboratory, and we were surprised by the fact that we were able to isolate some components from it through special instruments, and finally obtained some of the results of the analysis." The doctor glanced at Xiao Yuan with a strange gaze, and then said.

"What did the analysis come out of?" Xiao Yuan asked, he could speculate that the reason for such a result was related to the antidote that Lao Hu gave him, but he didn't know what the result of this antidote would be, and he was very curious.

"Part of the results show that there are more mixed substances in your blood, these substances are somewhat similar to the substances in Xia's blood, but they are very different, and the resistance of your blood is caused by this substance, and we have also done some other experiments, and found that this substance has a strong decomposition effect on general viruses or toxic substances, that is, as long as there is this substance in your blood, you will rarely get sick in the future." The doctor said.

"So will there be any side effects on me from these substances, and will they stay in my bloodstream forever?" Xiao Yuan asked again.

"I don't think it should always be in your blood, after all, people have to metabolize, with metabolism, these substances in your body should be gradually eliminated from the body until they disappear completely, as for the side effects, we also need to do further examination." The doctor said.

"So I'm going to have a new blood draw today?" Xiao Yuan asked.

"Yes, of course you are not our scheduled patient, so you can refuse, but out of the responsibility of the doctor, I advise you to take it seriously and cooperate with us for further examination." The doctor said.

"Okay, I'll cooperate." Xiao Yuan said.

"Then come with me, both of you." The doctor stood up, took Xiao Yuan and Xia Jiuying to the blood collection room, collected some of their blood, told them to remember to come on time to get the results, and let them go.

Although there was no definite conclusion, at least the doctor's words also revealed some information, Xiao Yuan and Xia Jiuying's bodies will not have anything to do for the time being, so when they came out of the gene laboratory, they were in a very good mood, and they discussed what delicious things they should do to celebrate when they went home, but they didn't want to meet Jessica again when they walked to the door of the laboratory, counting it, since the last time they met in San Francisco, they have only seen each other for five or six days, but too many things have happened during this period, So much so that Xiao Yuan felt like he hadn't seen her for a long time.

"Wait a minute, do you have time, I want to treat you to dinner." The two sides exchanged a few words, and Jessica was surprised to make such a request.

"What's the matter?" Xiao Yuan asked, he didn't have any arrangements for the evening, but he was curious about Jessica's sudden invitation to dinner.

"There are some things I want to tell you, but it's not the main reason, the main reason is that everyone is Chinese, and they are interested in the same field, so they should contact more and strengthen exchanges in the future." Jessica said.

"Okay, I'll leave Yingying's dinner with you to arrange, you're a rich man, so I won't say anything pretentious like inviting you to dinner." Xiao Yuan said.

"Okay, you guys wait, twenty minutes at most, and I'll be out." Jessica said, and then went to the genetics lab.

"Xiao Yuan, Jessica said that everyone is from Huaxia, what's the matter, is she also from Huaxia?" After Jessica left, Xia Jiuying asked puzzled.

"Jessica is the daughter of Ouyang Shi, president of the San Francisco Chinese Business Association, naturally a Chinese, by the way, her Chinese name is Ouyang Jie." Xiao Yuan said.

"But her hair and her complexion don't look like a Chinese." Xia Jiuying still had some questions.

"Maybe it's because of the mixed race, you know that many of the Chinese people who live in the United States are married to people of other races." Xiao Yuan said.

"Well, what do you think Jessica is going to do with us?" Xia Jiuying obviously accepted Xiao Yuan's speculation and asked instead.

"I guess it has something to do with the Innovation Lab, you forget that she wanted to invite me to join the Innovation Lab, but I didn't say yes." Xiao Yuan said.

"It's possible, forget it, we'll know when we eat." Xia Jiuying said.

Jessica didn't let Xiao Yuan and Xia Jiuyingwai wait long, and soon came out of the laboratory, and then went to eat with them.
