Meng Chenjun came over and said, "I want to listen, too."

"Take out the tape recorder and put it in the living room." Grandpa Meng expressed that he wanted to hear it too.

Meng Chenxi hurriedly said, "No, the eldest sister-in-law and second brother are busy, which will affect them."

In desperation, Grandpa Meng walked over with the newspaper and insisted on following them to their room to listen. Meng Chenxi couldn't stop his grandfather.

Lin Shangxian was left in the living room.

Seeing that everyone in his family had come, Meng Chenxi was thinking about the bad thing when he remembered that he was the only one left, but when he looked out, he disappeared. Everyone seemed to know who she was looking for to tell her: "He went to Teacher Ning's place."

Ning Yunxi blinked when she saw Lin Shangxian coming: "Why don't you follow them when they are going to listen to the tape?"

Lin Shangxian thought, why didn't she let him listen to him and he had to follow him.

Meng Chenyi looked up and laughed at the embarrassed old classmate, and whispered: "Eighty-mostly her cassette has a secret to you."

Lin Shangxian turned around and narrowed his eyes at his old classmate: You are not kind, and you say what your sister is saying behind your back.

Ning Yunxi smiled and looked at them and did not expose them.

Lin Shangxian was actually just like Meng Chenyi, who was quite curious about what Cao Ximin had written on more than a dozen pieces of paper, so he came to Meng Chenyi and looked at Cao Ximin's letter paper together.

As he looked, his expression was as serious as Meng Chenyi.

"What he wrote is quite difficult, right?" Lin Shangxian asked.

Meng Chenyi frowned, saying, "If it weren't for Cao Ximin's letter, he wouldn't have expected the gap between China and abroad." Some situations were said to be true, but they did not say that they were not as painful as Cao Ximin's personal experience and recorded.

"I thought he went abroad to learn computer technology like you or mathematics, because he won the prize in mathematics," said Lin Shangxian.

This was originally thought, which Meng Chenyi thought. But don’t forget that Cao Ximin’s teacher is his sister-in-law. Ning Yunxi’s long-term vision is even admired by returning scholars like Dou Xiao.

Cao Ximin went abroad to learn biotechnology.

"Computers are not new technologies in this era." Meng Chenyi admitted, "To be precise, they are technologies from the 1960s."

Since Lin Shangxian studied medicine, he has no idea about these science and engineering sciences, so he can only listen to the old classmates. What the old classmates said is indeed a bit beyond his expectations. After all, in the cognition of ordinary people, computers are already very high-end. The result is actually from the 1960s. It can be seen that the gap between domestic cognition and technological frontiers is huge.

"Sister-in-law." Meng Chenyi asked Ning Yunxi to answer.

Ning Yunxi nodded to them and said, "Plastic technology in the 1940s, transistor technology in the 1950s, computer technology in the 1970s, microelectronic technology in the 1980s, and new technology in the 1980s belongs to biotechnology. What is biotechnology? It is a technology that directly or simulates the use of animals, plants, microbial organisms, and the application of biological science and certain engineering principles to develop organisms or their components. In other words, biotechnology breaks the genetic boundaries between species and genera of organisms, making directional transformation and cultivation of new biological species possible and reality. What is the result of this? It will cause another great change in materials science, and make all applied science and technology closer to nature, that is, the field of God mentioned in the West. Chen Yi, the computer technology you learned, will also gradually get closer to the scope of using biological technology."
