Even though I have rehearsed it several times, my mind is filled with a bunch of messy etiquette and procedures.

At 5:28, when this moment of good intentions comes.

Wei Kang's brain still went blank uncontrollably.

Every muscle on his face was tense, maintaining an expressionless and serious look.

A bright red python robe was put on his body, and he walked step by step on a fixed route, making a series of movements like a puppet with string control, and subconsciously swallowing a mouthful of saliva from time to time.

That's the only thing he can do.

To outsiders, he looked very serious and decent in the solemn atmosphere of the scene.

Only he himself knew that deep down in his heart, the two emotions of excitement and tension were intertwined, like a symphony, which resonated strongly with the entire solemn environment.

Under such circumstances, it's already good if he can hold back his tears.

When the final hand-holding ceremony was held to represent the completion of the ceremony, the two newlyweds held hands together.

He held her hand and looked at her affectionately, thinking to himself.

We finally came together and a new life began.

He and she, at this moment, burst into tears.

When all the ceremonies were over, the two of them had something to eat, rested their bellies, changed into toasting clothes, and toasted to the guests one by one.

After toasting and seeing off the guests, it was already past 10 o'clock in the evening.

The whole wedding is finally over.

Watching the guests being sent back to the hotel one by one, Wei Kang took the bride's hand and quickly got into the back seat of the car.

He leaned back on his seat exhausted, feeling relieved as if he had accomplished something big.

"Great, everything is perfect, no flaws at all."

"Even better than the wedding I imagined." He thought to himself, reaching out and holding the bride in his arms.

The two of them cuddled together, looked at each other and smiled, both too tired to say a word.

The car started quickly and sped towards Kunshi.

The wedding night was spent in fatigue like this.

The next day, the most popular thing on the Internet was the edited video of this wedding.

People talked a lot and regained their yearning for a beautiful wedding.

Many people left messages on Wei Kang's homepage to express their love and blessings.

"Originally I didn't even plan to get married, but after watching Mr. Wei's wedding, my passion suddenly rekindled."

"Thank you Mr. Wei for providing us with a new idea. My husband and I also plan to have a Chinese-style wedding like this."

"This is the kind of wedding we Chinese people should have, solemn and grand!"

"Looking at it, I couldn't help crying. I don't know when the one of mine will show up. I'm looking forward to his arrival!"

"If I hadn't been poor, I would have hired the most professional team to customize a Chinese-style wedding."

"I have to work hard to make money and organize a wedding like this for Wanwan!"

"It's over the limit. I'm going to report it to the Ministry of Etiquette. [Dog Head]"

"Put it out upstairs and let me do it. [Dog Head]"

"You guys are going too far. Haven't you seen that the etiquette department is filming this wedding as a promotional video?"

“This sense of history, culture, heritage, and ceremony, I love it!”

"This is the kind of wedding a great country should have. I also want a Chinese-style wedding."

"Woohoo, I am a single dog.

"The best Hanfu wedding on the Internet. In addition to the gorgeous decoration, the solemnity of the ceremony, and the silent vows blending silently, there was no comedy, tears, or vulgarity. We only saw respect and love for each other, which made us realize the true meaning of marriage. significance."

"Learn from Mr. Wei, restore solemnity and solemnity to weddings, and reject marriage troubles starts with me."

"From beginning to end, this wedding reflected the Chinese etiquette in every aspect. It made me tremble all over."

"It is recommended to post it to an external website so that foreigners can see a real Chinese wedding."

"It's late. I just uploaded a video of the wedding on YouTube. It seems to have been taken by Corinna. The couple's costume styles have already gone viral on the Internet."

"Then we have to move out quickly. We must not let the people from the Bang country see it. You know, they will use it to apply for World Heritage."

"It really feels like a ceremony. The best memory in this life is nothing more than this. It was a blast!"

"As expected of a national husband, only Mr. Wei can realize a woman's ultimate dream."

"A wedding of the century with everyone's blessing, this is the correct way to marry into a wealthy family."

"Who wouldn't want a wedding like this? It's full of ceremony."

"It must be very expensive. A poor guy like me must not be qualified."

"Mr. Wei's is definitely expensive. It is said to cost tens of millions, but ordinary people can afford it."

"My wedding last year was also planned. Although it was not so grand, it was really great. I even cried. Sisters, you must have a Chinese-style wedding. You will never be disappointed."

"Sister, I am a traditional wedding host. Customized weddings are not as expensive as everyone thinks. The simplified version in the video does not cost more than 100,000 yuan, including costumes, makeup and props. If you need it, you can contact me privately. chat."

"It would be great if everyone could have one or two Chinese-style dresses as standard for weddings or formal occasions in the future. Watching this video, I feel like that day is not far away."

As if to confirm this, many wedding guests posted photos of themselves wearing Hanfu online.

They were all wearing Ming Dynasty official uniforms specially customized for this wedding. They were well-made. During the previous live broadcast, they just flashed by in front of the camera and did not leave many records.

This time I took a special photo and posted it online. I saw Yishui's purple robe and black gauze hat all appearing in the photo.

The scene was quite shocking, and netizens couldn't help but exclaim.

Especially after Yu Dong and Le Jun also posted photos of themselves at the wedding.

Netizens are excited.

"It's outrageous. Le Jun actually gave himself three strands of beard."

"Yu Dong also gave himself a mustache. He's really drunk."

"Familiar faces, unfamiliar looks, almost unrecognizable."

"Big guys also have a childlike side, haha."

"It's so funny. Didn't these two people fight when they met?"

"Sanqing has invited many customers and suppliers this time. It's like a business summit."

"Mr. Wei is indeed very capable. Even the guests' dresses are so exquisite."

It has to be said that as the leading idol, Wei Kang’s ability to carry goods is truly amazing.

Under the guidance of him and the guests, Chinese weddings became completely popular, and Hanfu became popular as well.

Although Hanfu has always been popular among young people, there are few truly heavyweights who wear Hanfu and support it.

This time, everything is different.

When elites all wear well-made Hanfu and it is broadcast on TV stations, it will undoubtedly cause a trend.

This official recognition is of great significance and proves a point.

Hanfu is no longer a small circle’s self-entertainment, but an officially recognized national costume.

Just like the kimono of Sakura Country and the hanbok of Bang Country, it has the status of appearing in formal occasions.

The Chinese people also have a kind of dress that can represent cultural heritage and wear it to attend important occasions.

In this way, the sales of Hanfu manufacturers that are somewhat famous on the Internet have grown rapidly.

The business of Hanfu experience centers in various places is also booming.

The national style craze quickly swept across the country.

In the streets and alleys, there are many more young ladies and brothers wearing Hanfu and going shopping than usual.

Otakus like Wei Kang are also keenly aware of this trend.

After the National Day holiday, he started to go to work. When he looked out the office window, he spotted many figures wearing Hanfu and wandering around Sanqingyuan.

There are men and women, all in ancient style. The woman is carrying an embroidered bag in her left hand and a small round fan in her right hand. They are walking in the beautiful Sanqing Garden, stopping from time to time to pose and take photos.

The man wore a turban and a green shirt, and held a folding fan in his hand, waving it gently, looking like a romantic scholar.

"They should be here for a visit to Sanqingyuan. They all look pretty good." Wei Kang couldn't help but smile.

He watched it with interest for a while, then returned to his desk again and looked through the progress of the project during this period.

"Both nanopills and artificial blood have been successfully produced in laboratories and have entered the animal testing stage."

"After all, it is a mature technology provided by the system. It is not too difficult to reproduce it in the laboratory."

"Next, it depends on the results of animal experiments and clinical trials."

"Of the two projects, artificial blood is more important and should be ranked first in priority."

Wei Kang looked at the artificial blood project and his face became serious.

Artificial blood is of extremely important significance for regenerative medicine.

Not only are blood banks often in need, the medical community needs large amounts of fresh blood every day to save lives.

In fact, the human body is a complex system composed of many different parts, all of which are indispensable.

Skin, joint cartilage, cornea, blood, blood vessels, trachea, bladder, heart, brain, etc.

All the components are perfectly combined to form the entire human body.

In the entire human body system, blood plays an important role, connecting all organs and continuously transporting nutrients, energy and oxygen.

This is why people often compare the rivers that carry supplies across the country to blood.

For a machine like the human body, building all the parts from start to finish is not something that can be done overnight. It can only be done step by step from easy to difficult.

Just like upgrading to fight monsters, you improve your skills level by level, hone your weapons, and then defeat the final boss.

As soon as Duan Bu entered the scene, he brandished the lowest level weapon and ran straight towards the biggest boss.

Being able to create the most complex human organs with full functionality is still an elusive goal.

But many of the building blocks of specialized organizations have come a long way.

At present, humans have been able to create the simplest organs, such as skin, which are flat and relatively hard, which is the easiest step to achieve.

Some biomaterials used in plastic surgery and ophthalmology, such as cornea and cartilage, are also being developed.

The next level of complexity is creating tubular structures such as blood vessels and tracheas.

Hollow, non-tubular structures like the bladder are at the next level of difficulty.

The holy grail in this field is making solid organs like hearts, kidneys and livers.

Artificial blood is probably located between the skin and blood vessels and is an indispensable part.

Human research on artificial blood has a history of decades and some results have been achieved.

The artificial blood currently used clinically is a white fluorocarbon emulsion that has an oxygen-carrying capacity that is twice as high as blood and 20 times as high as water, regardless of blood type. It can be used to temporarily replace some of the functions of blood.

After fluorocarbon artificial blood enters the human body, it can transport oxygen from the lungs to various parts of the human body just like real blood, and can transport carbon dioxide to the lungs and be excreted from the body.

From the perspective of oxygen metabolism, it is truly artificial blood.

However, this kind of artificial blood only has the ability to carry oxygen, and does not have platelets, plasma and other components. It can only be used as a substitute for hemoglobin and cannot truly transport nutrients between organs.

Therefore, the real promising direction for artificial blood lies in the field of stem cell hematopoiesis.

After the advent of iPS stem cell technology, scientists have been able to induce human somatic cells to generate pluripotent stem cells and continue to generate embryonic stem cells.

From this point of view, it is possible to induce and transform human somatic cells into hematopoietic stem cells, but the subsequent development is not satisfactory.

Hematopoietic stem cells are universal cells in the human body that can become any kind of blood cells, including red blood cells, white blood cells, and platelets, all of which are transformed from it.

Under normal circumstances, there are a large number of hematopoietic stem cells inhabiting the human body. There are about 3kg of hematopoietic stem cells in an adult, but 95% are in a dormant state and only 5% participate in daily hematopoietic activities.

Only when the human body loses a large amount of blood, the dormant hematopoietic stem cells will become active immediately.

This is because if hematopoietic stem cells multiply too much in the body, blood diseases such as leukemia will occur.

When expanded in vitro in the laboratory, hematopoietic stem cells will die quickly, lose their ability to self-renew, and cannot differentiate into other blood cells.

Research on artificially inducing hematopoietic stem cells to produce blood has continued for many years, but there has been no progress.

Only now, with the artificial blood technology provided by the system, has a major breakthrough been achieved in this field.

This technology mainly has two key breakthrough points.

One is to allow hematopoietic stem cell transplants to maintain a self-renewing state and continue to multiply in the laboratory.

In this way, there will be a steady stream of fresh blood.

The other is to remove the blood group antigens on the red blood cells in fresh blood, thereby turning it into a universal blood suitable for transfusion needs of different blood types.

When universal artificial blood is produced, physical or chemical methods are used to separate various active components in the blood and make high-concentration, high-purity blood products.

According to the patient's condition, whatever ingredients are needed are given.

In clinical medicine, this is called component transfusion. It is one of the symbols of modern blood transfusion and has become widely popular.

Fresh blood passes through a blood separator and is separated into white blood cells, red blood cells, platelets, and plasma for use in various situations.

Whole blood transfusion is only required in cases of severe acute blood loss and massive bleeding.

Otherwise, appropriate blood products will be transfused according to different situations.

For example, patients with anemia will receive red blood cell transfusions. Patients with severe thrombocytopenia and bleeding tendencies also need platelet transfusions.

In addition, there are granulocyte transfusions to control bacterial infections and plasma transfusions to supplement coagulation factors.

Apheresis technology is very mature, so as long as there is a large amount of fresh blood to fill the blood bank, component transfusion is not a problem.

These two key technologies are closely related to the expression of two genes.
