Several soldiers didn't quite understand what was said, but they knew one thing: this lithography machine was extremely powerful.
Mengzi asked again: "Sister-in-law, are you going to build a photolithography machine?"
“I have this idea.”
Jiang Yan nodded and continued to explain her ideas to everyone.
"The communication conditions in China are too poor. I want to improve them and see if we can achieve instant communication.
If this can be realized, everyone will have a communication device in their hands in the future, and can report any situation to their superiors immediately."
For example, during the ambush before, if we had this kind of communication machine, we could have immediately notified the regiment, and it wouldn’t have been so dangerous later.”
"Is it still possible?"
Mengzi and others in the back seat of the car were stunned. They couldn't imagine what kind of things could be reported at any time. On the contrary, Lu Yunsheng understood it well.
"Wife, do you mean something like a walkie-talkie or a walkie-talkie?"
“That’s about right.
In fact, the accurate description of this thing should be a portable telephone. Now the telephones in our group are all wired, and there are only one or two of them, and each transfer requires manual labor.
But if it is made wireless, and information is transmitted in the form of radio waves, and each transfer is completed through a machine, the efficiency will be much higher.
Without the constraints of telephone lines, this portable phone can be carried around.
Users can use their mobile phones to make real-time calls to people across the country or even the world from anywhere.”
“So amazing!”
"Sister-in-law, this kind of mobile phone technology should be very difficult, right?"
Jiang Yan smiled and said, "Of course there are difficulties. For example, the lithography machine I mentioned just now is a very important tool for manufacturing chips, and chips are the core components of mobile phones I mentioned."
After hearing what Jiang Yan said, everyone suddenly felt that they would not be able to see it in this lifetime, but future generations might be able to.
However, Lu Yunsheng saw something about national strategy from it.
"Wife, I think this thing can be done well."
The speed and efficiency of information transmission are very important in war, and sometimes can even determine the outcome of a war.
If mobile phones can really achieve instant communication anytime and anywhere, then China's military combat effectiveness will be taken to a higher level.
"After I get back, I'll write to Engineer Chen and Professor Tai to see if the military factory has any conditions."
Mengzi was very curious and asked Jiang Yan: "Sister-in-law, how big is the mobile phone you are talking about?"
Jiang Yan stretched out her hand. "It's about the size of my palm. It shouldn't weigh more than half a pound. Otherwise, it would be too heavy to carry."
"What?"
"The palm is so big, and it only weighs half a pound?"
"Oh my goodness, is there really such a small phone in the world? It's even smaller than the one in the political commissar's office."
Mengzi and the others had their cognition refreshed again. They felt that they could learn a lot by following Jiang Yan.
They had never known about fermented feed before, but later the regiment had its own biogas generator that could generate electricity using pig manure.
Now that there is such a small phone, several people admire Jiang Yan very much.
Along the way, several people asked various questions out of curiosity, and Jiang Yan answered them patiently and explained them one by one to everyone.
When they returned to the Second Group, they were still a little reluctant to leave, because the future that Jiang Yan described to them was so desirable.
The car stopped at the gate of the family compound. Jiang Yan got out of the car, closed the door, and waved goodbye to several people.
"Goodbye, I'll tell you something else later when I have the chance."
"See you later, sister-in-law."
Mengzi and the others also smiled and waved. Lu Yunsheng looked at Jiang Yan and said with a smile, "Wife, you go home first. I will report the situation to the political commissar and come back."
"Okay, go ahead."
After the car left, Jiang Yan turned around and went back to the family compound.
By this time, the sky had darkened and the moon had risen. Fortunately, the Second Regiment could now generate its own electricity, and the family compound was brightly lit at night.
Several large light bulbs were hung on the road outside the yard. Under the bright light, Jiang Yan returned to her own yard.
squeak!
The door was pushed open, and a pair of green eyes appeared in the dark courtyard. Jiang Yan was startled.
"Meow~"
A soft cat cry sounded in the darkness, and Jiang Yan complained, "Heimi, you are going to scare me to death. Don't do this in the future. Sooner or later, I will scare you to death."
Taking out a flashlight from the space, Jiang Yan walked to the living room and turned on the light.
Heimi had come to her feet without her knowing. She turned off the flashlight and put it into the space. Jiang Yan walked to the cupboard, took out the ceramic jar containing cat food, and scooped a large spoonful into Heimi's food bowl.
Heimi hurried over to eat the food. Jiang Yan added some water to it, then squatted down and smoothed the hair on its back.
After watching Heimi eat for a while, Jiang Yan got up, washed her hands, and went into the kitchen to start cooking dinner.
It was getting late, so Jiang Yan prepared to make some dough dumplings.
At the same time, Lu Yunsheng also came to the office of the regiment political commissar.
Seeing Lu Yunsheng coming back, Sheng Pinghua hurriedly asked, "How is the situation? Is your wife okay? Did she have an accident, or did she encounter a spy again?"
Lu Yunsheng walked in quickly and said in a serious tone, "They are spies, and they want to kill Jiang Yan. They even set up three ambushes and used Molotov cocktails."
Sheng Pinghua frowned and couldn't help but swear, "Damn it, why are there so many spies in Zhanchuan?"
Lu Yunsheng was also helpless. If this continued, Jiang Yan would not be able to stay in Zhanchuan, and Tai Sicheng and his research institute would have to be moved.
After explaining the details of what happened to Sheng Pinghua, Lu Yunsheng prepared to go home after get off work.
"Political Commissar, this is roughly the situation. I suspect those people have set up an ambush on the way to the institute. It would be best to send someone to check it out.
Also, on the way back, my wife mentioned a concept of a mobile phone, I'm not sure about it, I'll let her tell you when she's free."
"A new idea?" Sheng Pinghua's eyes lit up and he asked hastily, "Is it another plan to make a fortune?"
"???"
Lu Yunsheng hadn't thought about it this way, but now after hearing what Sheng Pinghua said, it seemed that he could really make a fortune.
He said uncertainly: "I think I can make a fortune."
"Wait a moment, I'll call the military district and we'll go together. Tell me everything on the way."
Sheng Pinghua called Lu Yunsheng and quickly called the military district back. When they heard the news that Jiang Yan was safe, the people at the military district also breathed a sigh of relief.
"As long as it's safe, as long as it's safe, we'll have to interrogate those spies carefully. The commander has said that we must thoroughly clean up the entire Zhanchuan this time."
"Okay, I'll have someone start the interrogation tomorrow, and notify the military district as soon as there is any news."
After hanging up the phone, Sheng Pinghua called Lu Yunsheng to go back home together. On the way, Lu Yunsheng also told Sheng Pinghua in detail about the mobile phone matter.
The more Sheng Pinghua listened, the more he felt that this was another opportunity to make a fortune!
