Tai Chi Hall, Li Su's office.

Huang Qi took officials from the Machinery Department of the Ministry of Science and Technology to Li Su's office, and when he entered the door, he found that Li Dan, the Minister of Industry, was also here.

"Your Majesty, what kind of machinery is this time?" Huang Qi asked, pointing to a mechanical wall chart on the wall.

Li Su said: "This is called a steam engine......

Li Su introduced the principle of the steam engine and its uses.

When they heard that the power of the steam engine could be better than hundreds of horsepower, Huang Qi and the others were excited.

Huang Qi said that after returning home, a steam engine research and development team was immediately set up, and trial production was carried out immediately according to the drawings.

Ash Naqing took out a complete set of steam engine drawings and handed them to Huang Qi. Then on the wall, another set of mechanical drawings was hung.

Li Su pointed to this set of drawings and said: "This is called the flat roll flattening rolling molding process, which is used to process and produce copper wire and iron wire......

Li Su introduced the basic principle of the flat roll flattening and rolling molding process, and then said: "This matter should be studied first, and after the successful trial production of the Ministry of Science and Technology, it will be handed over to the Ministry of Industry for mass production."

In particular, iron wire, after being produced, is processed into barbed wire, which can play a huge role in the campaign against Tibet. ”

Huang Qi, the Minister of Science and Technology, is very comfortable! The vast majority of inventions and creations do not need him to worry about at all, the emperor provides him with drawings and related technical information, and they just carry out trial production.

However, even if the trial production is only carried out according to the drawings and technical data, a large number of scientific and technological talents have been cultivated for the Ministry of Science and Technology.

After the task was explained, Li Su said: "Li Dan stays for a while, you can retreat first." ”

After everyone left, Li Su said: "Second brother, Wuyun said that the day after tomorrow is Gao Wa's birthday, and she wants to do it for her personally, if not, you can come over together." ”

Li Dan said: "Brother Su, this little thing still makes you and your sister-in-law worry about it, it's true, if you don't say it, I really forgot about it." ”

Li Su said: "In the past, we had three evils, playing together all day long, and our lives were relaxed and comfortable.

Now that I'm older, I'm busy every day, and I don't have the opportunity to see each other. In the future, when you and Duhe are free, you will take your wife and children to walk around with me, and the brothers will often get together. ”

Li Dan also said with emotion: "Yes, I am so busy every day now, I really miss our old days." ”

Li Su said: "Then it's decided, the day after tomorrow, you will bring Gao Wa over, and then call Du He's family, let's be lively." ”

As he spoke, Du He asked to see him.

Li Su smiled: "I really said that Cao Cao Cao will arrive, as soon as he thinks about him, he comes." ”

As soon as Du He entered the door, he saluted Li Su and said, "Minister Du He sees the emperor." ”

Li Su smiled and said, "Third brother, you came just in time, my second brother and I are talking about you." ”

Du He smiled: "Big brother, second brother, what are you talking about me?" ”

Li Dan said: "What the eldest brother means is to let our family move around often, so as not to be divided."

The day after tomorrow, my Gaowa will celebrate her birthday, and Wuyun's sister-in-law will personally handle it for her, and let you bring Yangcheng and Tian Zhen over together. ”

Du He said with a smile: "What I said is that our brothers haven't been together for a while, I think it's better to hurry up than to hurry, let's go to Chang'an World tonight." ”

Li Su smiled: "Okay, it's decided, see you at the gate of the big world at six o'clock." ”

Du He said: "Brother Su, I have something to report to you. ”

Li Dan said: "You have something serious to discuss, then I will leave first, and see you in the evening." ”

After Li Dan left, Du He said: "Nuo Haobo has now been escorted to Lhasa, and the rescue team has entered Tibet half a month ago, and the rescue operation should be launched in the next few days." ”

Li Yu said: "Nuo Haobo must be saved, he just joined our Datang, and he encountered this kind of thing, we must rescue him and give an explanation to the original Tuyuhun people and his family." ”

Lhasa.

In a small courtyard north of Lhasa, the king of Qinghai County, Nuo Haobo, was imprisoned here.

After being captured, he was escorted all the way to Lhasa, where Songtsen Gampo met with him and persuaded him to surrender. Nuo Haobo did not agree.

Considering his influence on Tuyuhun, Songtsen Gampo temporarily withheld him and put him under house arrest.

The rescue team, with Liang Hongmin, director of the Tubo Division of the Overseas Intelligence Bureau, as the team leader and Huang Haiming as the deputy leader, selected 15 Tibetan-speaking soldiers from the Flying Tiger Army and 20 Tibetan-speaking soldiers from the Tuyuhun people to form a rescue team.

They set out from Weizhou in Longyou Province, disguised themselves as Tibetan soldiers and infiltrated Tibet, and arrived at a farm outside Lhasa.

This is a den of the Overseas Intelligence Service. The operatives briefed the rescue team on what they had.

The place where Nuo Haobo was imprisoned was a thousand-strong battalion of the Tubo Gasang Battalion (warrior battalion, equivalent to the Imperial Forest Army), and it was impossible to storm it.

Liang Hongmin and Huang Haiming discussed and decided to outwit.

The mid-level and above officers in Tibet were all members of the slave-owning class, and the families of the thousands of families in this camp lived in the urban area outside the camp.

On this day, a Tibetan merchant came to the house of Qianhu. This merchant was very familiar with Qianhu, and he told Qianhu that he was going to leave Lhasa and go to Qamdo, and that his cook's family was from Lhasa, and he did not want to leave Lhasa, and wanted to ask Qianhu to arrange an errand for him in the military camp.

Chiho remembered that there happened to be a cook who didn't come to work two days ago, so he agreed.

The new cook is very good at coming to things, and after a short time, he is very familiar with the people around him, and the chef who used to deliver food to Nuo Haobo saw that the new cook was so good that he sometimes called him to deliver food.

Soon after, the new cook began to deliver food to Noho Bowl alone.

This cook, of course, was the one who was planted by the Overseas Intelligence Agency. Of course, the previous cook was eliminated by the rescue team.

A month later, when the time was ripe, Liang Hongmin and Huang Haiming decided to take action.

On this day, a relative of the new cook came to visit him, and when it was time to deliver the meal, the cook asked his relative to help him carry the food box and go to deliver the food to the noho bowl together.

Nuo Haobo is under house arrest, and the Tibetan soldiers are not strictly guarded, as long as he does not go out of this courtyard, how to toss, the soldiers are too lazy to pay attention to him.

After the cook and his relatives went in, about the time of a meal, they came out with a food box.

At this time, Nuo Haobo appeared at the door of the house and coughed loudly, and his coughing attracted the attention of the Tibetan soldiers, and the cook and his relatives left.

It wasn't until three days later that the Tubo soldiers in charge of guarding it found out that the Nuo Hao bowl did not come out of the house these days, and felt a little strange.
