Thanks to Tianhai Xiangyun for his generous reward of 1888 coins.

In the summer of 1953, the Volunteer Army was south of Jinseong, North Korea, and the Volunteer Army concentrated 1,094 artillery pieces to launch the last offensive campaign on the Korean battlefield. Among them, there are five rocket artillery regiments and nearly two hundred Katyusha rocket launchers!

Even if the Republic did not pay attention to rocket artillery with a faster rate of fire and more powerful firepower than ordinary artillery at that time, Lao Maozi's use of hail rocket artillery against the PLA during the Battle of Zhenbaodao gave them enough promotion.

In the base, it has become stable since seventy years, although the base is still controlled by Su Mingyi and his party, but it should not be without much progress now.

"At present, the quality of our rocket engines is not up to par, the flight of rockets is not stable enough, and the launch ignition control device is ......also unstable." Regarding Liu Yijiu's question, even if he knew that he could not provide any advice, Wang Shunyi would answer all questions.

"Yes, Xiao Liu, these questions have been bothering us for a long time. The material aspect is a big problem, since the teacher Yao Tongbin was killed, our domestic development in this area has been even slower......" Wang Shunyi said a little old man next to him with a look of regret.

Yao Tongbin, Liu Yijiu knows this person. One of the main founders of the Republic's Institute of Missile and Aerospace Materials and Technology is a two-bomb and one-star father, and a two-bomb and one-star martyr...... In this matter of aerospace materials, the most gifted people of the republic! Unfortunately, in 1968 he was killed, at the age of 46, which was the loss of the Republic in this regard. When Premier Zhou, who was attending a meeting in the Great Hall of the People, heard the news, the teacup in his hand fell off......

Especially in the 70s, when the Long March 1 rocket was developed, because the engine materials were not up to par and failed repeatedly, the researchers finally solved the material problem based on a French paper in a foreign journal, and the author of this paper was Yao Tongbin!

"If only Jia Yiming were here. At least, the material problem should be solved in my hometown. He was also the authority of the 703 Institute back then......"

Hearing the name Jia Yiming, Liu Yijiu felt very familiar.

This name, he should have heard it somewhere.

"He's a materials expert? Aren't there a lot of material experts in our base? Liu Yijiu asked suspiciously.

In this base, many researchers were previously assigned here from the outside.

There are quite a few experts in various fields.

"In terms of rocket materials, we don't have experts here, the rest are conventional materials and aviation. For example, Lao Wei, he has more say in aviation materials, but not in aerospace......" Wang Shunyi pointed to the little old man next to him who was a little bald and wore a pair of huge black-framed plastic eyes.

It was Jia Yiming that this old man said that made Liu Yijiu feel familiar.

"Uncle Wang, did you say Jia Yiming, was he originally from the base? Is it from the Northeast, very tall and thin? Liu Yijiu suspected from the beginning that the middle-aged man had a story, which was fundamentally different from ordinary mountain people, even if he was dressed up as a mountain man more than a mountain man, but in his bones he felt the opposite.

In his bones, there is even a trace of innocence.

And is the name just a coincidence?

"If nothing else, he would have been among us. It's a pity that there was an accident on the way to this base, and then the base changed, no one can know where he is, and even the 703 Institute is currently inquiring about his whereabouts...... "The importance of talent, this is beyond doubt."

Liu Yijiu's words made Wang Shunyi's eyes suddenly light up, grabbed Liu Yijiu's shoulder, and asked Liu Yijiu with wide eyes, "Xiao Liu, have you seen him?" Where is he now? ”

"Uncle Wang, you've hurt me. I know a man named Jia Yiming, who lives in Hulu Village, not far from the base, and has little contact with the people in the village, and has three children alone...... "Liu Yijiu immediately told them the dirty things they had done to eat dried meat.

Even, the impression that Jia Yiming gave him was also said.

"Take us quickly, it's likely to be him. Even if he finds a base, it will be difficult for him to come in...... "Wang Shunyi is now like a patient who goes to the doctor indiscriminately, no matter whether the other party is Jia Yiming they want to find or not, they must also go and see." What's more, it is not far from the mountain to Hulu Village, and it does not take long to get there by car.

With rocket material specialists, their research progress will be much faster.

Liu Yijiu can be regarded as having seen the character of the older generation of technicians who do what they say, and now he didn't even have a chance to discuss his own design, so he was dragged by Wang Shunyi and Wei Mingshan to Hulu Village to find Jia Yiming. If it was a swoop or something, or the other party was not the Jia Yiming they were looking for, they didn't think about it at all.

They have been confined to this project for too long.

This project has been launched since more than 10 years ago, otherwise there would not be a large number of specialists in the base. Ten years have been wasted, and now that this project has been restarted, and it is still being started with the interference of the Military Commission, how can they sleep if they can't work it out as soon as possible?

Zheng Hao had never heard of Jia Yiming, and it was not easy for him to interfere with such a thing.

Wang Shunyi and them, he didn't want Su Mingyi to restrict them like he did at the beginning, as long as they did things seriously, he didn't bother to pay attention to them.

Staying in the cave for too long made Wang Shunyi and Wei Mingshan's faces very pale without a trace of blood. If it weren't for the fact that it was early spring and the sun was not easy to see in the mountains, it was estimated that they would have to get used to it before they could set off.

With the jeep provided by the base, it took less than 20 minutes to arrive at the entrance of Hulu Village.

It was just around noon and a little smoke was already rising from the village. Liu Yijiu took the two of them towards the thatched house of Jia Yiming's house, and when they arrived, they found that Jia Ling was packing up her things and carrying them outside, which was obviously to move!

"Jia Ling! Where's your dad? "Liu Yijiu's memory is very good, and Jia Ling's impression on him is too deep, an eighteen-year-old girl, only fourteen or fifteen years old, can it not be profound? If he had been in contact with more people outside, maybe this would not have happened.

"You are?" Jia Ling obviously has no impression of Liu Yijiu.

"The work clothes on your body are still the ones we changed for you......" Liu Yijiu pointed to the indecent work clothes worn by Jia Ling and reminded the girl.

Jia Ling's face immediately turned red.

This dress belonged to Luo Tong, and in the end, Liu Yijiu gave his work clothes to Luo Tong, who was wearing a fake collar and was a little unsightly.

At that time, it was autumn, and now, it is spring, and half a year has passed, but it does not affect people's memory.

"You're moving? Where did your dad go? Wang Shunyi obviously understood that the girl in front of him was the daughter of Jia Yiming that Liu Yijiu said, and when he saw that they were about to move, he couldn't help but ask eagerly. It is very likely that the other party is really Jia Yiming.

"Who?" Hearing the sound outside, Jia Yiming, who was packing up his things at home, came out and was stunned when he saw Wei Mingshan outside.

Liu Yijiu was also stunned when he saw Jia Yiming at the door.

When I first met Jia Yiming, this man was like a sloppy beggar. But today it subverted his cognition - his hair was cut short, combed into a big back, his thin face was cleanly shaved, he was wearing a brand-new Zhongshan coat on his upper body, a pair of dark pants on his lower body, no longer the kind he used to tie his belt, and he was wearing a pair of polished leather shoes on his feet!

Typical of a cultural person's dress!

"Lao Jia! I didn't expect you to be here all along! When Wei Mingshan said this, two crystal tears fell from the corners of his eyes!

"Is it really Comrade Jia Yiming?" Wang Shunyi didn't expect that the person in front of him, who was not at all like Liu Yijiu's description, was actually the rocket material expert they were looking for! After getting Wei Mingshan's nod, he stretched out his right hand to Jia Yiming, "Comrade Jia Yiming, on behalf of the base of the Ninth Academy, I sincerely invite you to join the Ninth Academy!" ”

"What about Director Liu Suzhi? My file has been lost, and now I am a black household, and I am no longer qualified to enter the Ninth Academy......" Jia Yiming said lonely.

Hearing Liu Suzhi, Wang Shunyi and Wei Mingshan both froze.

"Mr. Jia, Director Liu passed away six years ago. Now the director of the base has been transferred from the Fifth Machine Department, and Su Mingyi has been corrected on the spot...... The country is in ruins, and it is a good time for an expert like you to show his skills......" When the two stared at themselves, not knowing how to answer, Liu Yijiu said generously.

For Liu Suzhi's death, he has no hatred, only sorrow.

This sadness is not because he occupies the body of Liu Suzhi's son, but because of the harm caused to these intellectuals in this era.

"I don't have a file anymore, and my expertise has been lost over the years. I'm just a farmer, and now that the state is getting better, I just want to take my children back to our hometown in the northeast......" Jia Yiming sighed and shook his head.

His words told Wang Shunyi and the others that he was no longer the material expert he used to be.

This incident shows how much Yao Tongbin's incident hurt him at the beginning.

"Lao Jia, can we talk alone?" When Wei Mingshan saw this, he knew that if he didn't persuade Jia Yiming, he would probably never be able to find him again in the future.

This is a great loss for the defense industry of the entire country.

Jia Yiming looked at Liu Yijiu and Wang Shunyi, nodded, didn't say anything, but followed Wei Mingshan towards the outside.

"Lao Jia, Director Liu was killed at the beginning. The young man just now, his son, only returned to the base last year after sending him off, and I think you know the current situation in the country, it is a good time for us to show our talents. The rise and fall of the country is the responsibility of the husband, Su Xiu and the US imperialism are our enemies, only when the country is strong, can we live more freely......" Wei Mingshan took out a cigarette without a filter and handed it to Jia Yiming, pointing to Liu Yijiu, who was chatting with Jia Ling.

And, briefly talked about the original base.
