"Xiao Chen, are the students majoring in acting in the film and Television Academy ready?"

"Director Su, the students have arrived."

"Just a moment, let me inform you first."

In the office building of film and Television College of Wucheng University of Arts and science, Su Yangfan takes out his mobile phone and dials a call to President Ding.

Because today we're going to cast for the science fiction movie wandering earth.

But also choose the most important two roles, namely the hero Liu Qi and the heroine Han Duoduo. After the last exchange with President Ding, Su Yangfan knew that the best choice for these two roles was from the students majoring in performance in the film and Television School of Wucheng University of Arts and Sciences.

If you really can't choose a satisfactory role, go to the performance Department of other professional universities to choose.

Su Yangfan certainly understands president Ding's idea of giving priority to his students, and if he can really choose the right actors in the performance major of Wucheng University of Arts and Sciences, it will be the best, so as to avoid the subsequent work of selecting the leading role.

The reason why we chose the actors and actresses so quickly is that Su Yangfan has adapted the script from the science fiction "wandering earth" given by President Ding.

As well as the team members who filmed "contact beyond time and space" before, it's almost time to return.

Unexpectedly, they are still willing to leave the original company to make a science fiction film with Su Yangfan.

Most of all, the money is in place.

One day ago, Ms. an Yujia, the CEO of leap Group behind Wucheng University of Arts and Sciences, found Su Yangfan and said that the funds of leap Group had been put in place, and the money invested in the science fiction film "wandering earth" could also be put in place smoothly.

With money, Su Yangfan can start this huge science fiction film project.

Su Yangfan's initial investment in this project is expected to be at least 100 million yuan, because special effects are too expensive.

As a director, Su Yangfan naturally knows which pictures need special effects to burn money to shoot. This wandering earth tells the story that human beings have to push the earth away from the solar system due to the sudden drop of global temperature and the advent of various disasters. Almost the whole story needs special effects from science.

As a result, Su Yangfan's estimate is at least 100 million yuan lower. It may take more money to make the magnificent picture he described in his last chat with President Ding.

"Sorry, the number you dialed is not answered at the moment, please redial later!"

Su Yangfan dialed the phone, but no one answered.

"Well? Principal Ding didn't bring his cell phone with him? " Su Yangfan was very confused and said to himself.

In principle, it shouldn't be. President Ding's phone doesn't exist. I can't get through or no one answers unless president Ding's mobile phone is not around.

"Give Secretary Wen a try." Su Yangfan muttered and called Wen Ruohan, President Ding's close secretary.

Du ~ Du ~ Du ~

Du ~

"sorry, the number you dialed is temporarily unanswered, please redial later!"

It's the same tone.

This makes Su Yangfan feel strange, how Ding and Secretary two people at the same time can not contact it.

Are they at...

"Director Su, are we going to the casting scene now?" Assistant Xiao Chen asked Su Yangfan.

Su Yangfan couldn't help frowning, then shook his head slightly and said, "don't worry first."

President Ding paid special attention to the selection of actors and actresses in wandering earth. Last time, he said that President Ding would personally participate in the selection of actors and actresses.

But when it comes to casting, Su Yangfan can't get in touch with headmaster Ding.

Dududu ~

Dudu ~

"sorry, the number you dialed is not answered at the moment, please redial later!"

Su Yangfan called President Ding again, but no one answered.

At this point.

In the advanced medical laboratory of the experimental building of the Medical College of Wucheng University of Arts and Sciences, Ding Yue is taking Professor Yang Kaining from the Federal Institute of technology in Zurich, Switzerland, and five doctoral students of Professor Yang to learn about 3D bioprinters and related technologies in the laboratory.

Because this is a high-end medical laboratory, everyone has to change into a dust-free sterile suit before entering.

Ding Yue in changing clothes, mobile phone on the outside of the changing room, now there are two missed calls.

But Ding Yue didn't know.

"Headmaster Ding, this 3D biological printer in your school is really wonderful. It's... Incredible!"

Professor Yang Kaining's pupils were full of excitement after seeing this 3D biological printer in the laboratory.

This is the excitement he should not have at his age. Even if he has made any research achievements, Professor Yang Kaining has never been so excited.In front of Professor Yang Kaining, a white 3D biological printer looks ordinary, just like the ordinary printer case.

But this is not an ordinary printer. This is a 3D biological printer with extremely complicated internal structure.

3D bioprinter is a kind of precision mechanical equipment that can be driven by digital three-dimensional model, according to the principle of additive manufacturing, position and assemble biomaterials or cell units, so as to manufacture medical devices, tissue engineering scaffolds, tissue organs and other products.

Since the beginning of modern medicine, organ transplantation can save the lives of many patients with organ failure or damage. However, this technology also has some disadvantages, such as insufficient source of organs, unavoidable rejection and so on.

However, with the 3D biological printer, there are new technical means to solve these problems. The 3D biological printer first reads in the 3D model reconstructed or designed from medical image data, discretizes the model into multiple layers, and the computer controls the printing nozzle to "print" the "biological ink" composed of biological materials or cells layer by layer, and then repeats this process until the end Three dimensional tissue precursor was printed. Subsequently, the cells began to reorganize and fuse, forming new blood vessels and other tissue structures.

Next to the machine is a computer, and the person standing in front of the computer is Xu Bin, the most famous computer genius of Wucheng University of Arts and Sciences!

Beside Xu Bin, there is also a teacher from the medical school of Wucheng University of Arts and Sciences, who specializes in medical imaging.

"Professor Yang, now you completely believe that Wucheng University of Arts and Sciences has 3D bio printer. We are short of bio ink composed of biomaterials or cells."

Ding Yue said to Professor Yang Kaining with a smile.

Professor Yang Kaining nodded, his heart is still very excited and excited: "once this technology can be used in the medical field, it will be a great feat of biomedicine."

Although the use of 3D printers by Professor Yang Kaining sounds very mature in the field of biology, it is true that it is very important to use 3D printers.

At least those patients who are difficult to find a match of biological tissue and organ, or who are incompatible and exclusive in organ transplantation, finally have a perfect substitute that can ensure that the tissue and organ can be printed according to the demand!

"It's amazing. I love this research project!"

"Tom, look, 3D bio printer."

"There are many medical science and technology institutions in our country studying 3D biological printer. It's really unexpected that there are almost mature equipment in Xia country."

"It shocked me. It really changed my impression of Wucheng University of Arts and Sciences."

"This medical laboratory is really wonderful. I think many biological experiments can be done here."

After visiting the medical laboratory and the 3D bio printer equipment of Wucheng University of Arts and Sciences, Professor Yang Kaining's five doctoral students were all amazed.

They also have a disdain psychology, at this moment basically all disappeared, only for what they see now and feel praise and shock.

After all, there may not be such a medical laboratory at the Federal Institute of technology in Zurich.

"President Ding, I can't wait to start this biomedical project of your university." In Professor Yang Kaining's words, there is a taste of rubbing hands.

On one side of Xu Dongcheng after listening, not to mention how happy.

Ding Yue immediately asked with a smile, "Professor Yang, how long do you think it will take to produce perfect bio ink by combining bio tissue and cell material technology with 3D bio printer?"

This is a key issue.

At the same time, it is also the question that Xu Dongcheng wants to know most. After hearing president Ding's question, he can't help staring at Professor Yang Kaining.

"I strive to achieve this integration within half a year!" Professor Yang Kaining took a deep breath and said as if he had made a military order.

Half a year!

This time makes Xu Dongcheng very satisfied.

Because Xu Dongcheng had thought before that if Professor Yang Kaining could not be invited to Wucheng University of Arts and science, the worst would be to study the technology of biological tissue and cell materials, and the time needed would be unknown. Her baby daughter Xu Meijia might not be able to wait for the day when 3D biological printers can be officially used.

When Xu Dongcheng heard Professor Yang Kaining say that within half a year, he was as happy as the new year.

At this time, Ding Yue looked at President Xu Dongcheng with one eye, then withdrew his eyes and said to Professor Yang Kaining, "Professor Yang, if that's the case, it's really great."

If Professor Yang Kaining's biological tissue and cell material technology can be perfectly integrated with his own 3D biological printer of Wucheng University of Arts and Sciences within half a year, then the following clinical trials, application for national approval, etc. are efficient enough, three months should be no problem.

That's how it works out.It is preliminarily estimated that in more than half a year, the 3D biological printer of Wucheng University of Arts and sciences will be able to print out the first human organ liver.

And it's a liver organ specially made for Xu Meijia!

"Well, when will it start, now?" Professor Yang is looking forward to asking.

"No, Professor Yang, you come right after you get off the plane, and then you come to the laboratory. You haven't had a rest yet. You can be more efficient only after you have a good rest."

Ding Yue shook his head quickly.

It's really necessary to arrange for Professor Yang and his five doctoral students to have a good rest and do research on this kind of thing. They also need to have enough food and drink and have a good rest.

So.

Ding Yue took Professor Yang Kaining and they left the laboratory. When they returned to the dressing room, Ding Yue took out his mobile phone and looked at the time. As a result, he saw that Su Yangfan had made two missed calls to him.

"Well?"

Ding Yue, with a puzzled look, dials Su Yangfan back.

What's the matter with Su Yangfan calling himself?

Ding Yue has had too many things recently. When he is busy, he may forget some other things.

Almost all the biomedical engineering schools in Zurich have devoted their energy to this.

"Headmaster Ding, Director Su called me and sent me a wechat to ask me about you..."

Wen Ruohan's voice came from his ear.

"I see. I'm calling Sue back." Ding Yue nodded gently.

It seems that Su Yangfan really has something urgent to find himself? He not only called himself, but also called Wen Ruohan and sent wechat.

"Hello, Director Su."

When the phone was dialed, Ding Yue asked directly, "are you looking for me?"

"Headmaster Ding, I have contacted you."

"Just now I was in the laboratory with a foreign professor, so I didn't take my cell phone with me." Ding Yue explained it briefly.

"Oh, headmaster Ding, it's like this. The students of the performance major of the film and Television Academy are all ready to apply for the casting of wandering earth. Today they will have a audition. Headmaster Ding, last time you said that you had to choose the leading actor and heroine yourself, so..."

"it's this thing. You see, I'm so busy that I forget it, Well, that's right. I'll take care of the actors and actresses of wandering earth by myself

Ding Yue suddenly realized what it was like for Su Yangfan to find himself.

It's also very important. After all, whether the hero and heroine can make a good choice will have some influence on the success of wandering earth.

The success of "wandering earth" is related to whether Wucheng University of Arts and sciences can make money from film and television entertainment, and then put the money into the construction and development of Wucheng University of Arts and sciences like the box office revenue of "super Marines".

We need to know that there are still many departments in Wucheng University of Arts and science that need money to develop, and many students with outstanding learning ability can not get a chance to perform.

Because Ding Yue is short of money.

All the money has been used in the place where it should be used. It is necessary to expand the school campus, invest in lithography experiment project, graphene battery project, biomedical engineering project, and investment in animation major, as well as other aspects including leap Group.

"Headmaster Ding, it doesn't matter. We haven't started yet. We are waiting for you."

"Well, I'll be right over. Where is it?"

"Gymnasium."
