Seeing two famous Feng Shui masters in history holding this book "Chemistry", Zhang Nan knew that the matter had not been gone, so he left the Taishi Bureau and went to the Ministry of Works.

In fact, Zhang Nan was unwilling to put the Tiangong Department into the Department of Works. After all, there were so many people and eyes. Even Zhang Nan had no accurate idea of ​​what the Tiangong Department could do in the future. If the things inside were used by those who were interested, Zhang Nan's sin would be great.

So Zhang Nan decided to ask Wei Tianwu to see if there are any secrets in the Ministry of Works so that he can conduct scientific research quietly.

When he arrived at the Ministry of Works, Zhang Nan found Wei Tianwu and said straight to the point: "Mr. Wei, is there any secret place in our Ministry of Works?"

When Wei Tianwu heard this, he smiled and said, "Mr. Zhang is joking. Look at this Ministry of Works. It's just such a big place. Where can there be any secrets?" After that, Wei Tianwu pointed to the office location of the Ministry of Works.

"Hey, don't stick to this place. It's the place where craftsmen in our Ministry of Works make things. Is there any secret place?" Zhang Nan still didn't give up and continued to ask.

"It's true, but Lord Zhang, why are you asking about this?" Wei Tianwu was a little surprised. Where to work is not an office, why do you have to send a secret place? It's not about doing something shameful.

"Well, this is still inconvenient now. When my Tiangong Department is established, I will take Lord Wei to the Tiangong Department to take a look and Lord Wei will know." Zhang Nan scratched his head and said. No matter how much he told Wei Tianwu now, it would be useless and useless. Many things should be seen as real.

"Then I have to wait for it, but the Ministry of Works does not have this secret place. Lord Zhang might as well go and ask the emperor?" Wei Tianwu said.

"Okay, Lord Wei, go and do your business. I'm thinking of a solution." Zhang Nan said, knocking on his head. Indeed, it is still very difficult to do something that everyone doesn't want everyone to know.

Zhang Nan had no choice but to ask for help from the boss on this land, namely Comrade Li Er. Although Zhang Nan didn't want to see Li Er, there was no way. This matter would be impossible.

"What did you say? You need a secret place to carry out the work of the Ministry of Heaven and Works?" Li Er was lying on the warm bed and chatting with Empress Changsun. When he heard Zhang Nan ask for a meeting, Li Er didn't want to see him, but Empress Changsun was so virtuous that she asked Li Er to put state affairs first. As a last resort, Li Er announced Zhang Nan, but as soon as he came in, Zhang Nan asked Li Er a problem.

"Nothing wrong, it's best if you don't know about it, that's the best." Zhang Nan said.

"What do you want to put in the Ministry of Works? Is it so important?" Li Er asked with a frown.

"Does the emperor think that the sky-bombing thunder is important?"

"important."

"Is that Kanfeng Crossbow important?"

"important."

“Is the hot air balloon important?”

"Of course it matters."

"There are things in this Tiangong Department that are ten thousand times more important than these three." Zhang Nan said with a smile.

"Oh? What is it?" Li Er immediately became interested and asked when he saw Zhang Nan's appearance.

"Technology, talent." Zhang Nan said.

"What is this technology?" Queen Changsun asked. Although Zhang Nan didn't want to answer any of the 100,000 questions asked by the couple. There was no way. Whoever asked Comrade Li Er to be the emperor and did not want to answer.

"Technology is just about investigating things. Empress Changsun must know what investigating things is." Zhang Nan said.

Empress Changsun of course knew what it was to investigate things. Investigating things means to explore the principles of things and correct people's behavior. "Ge" means "exploring" here. "Book of Rites·Geo": "To be aware of things, then you can know the ultimate." Investigating things is an important issue in Confucian epistemological methodology, and the cornerstone of the "eight eyes" among the three pillars and eight eyes.

"Does this also take a secret place to explore the principles of things?" Queen Changsun looked strange.

"Ordinary things are not needed, but if they are important weapons of the country, then does the Empress think this needs to be done in a secret place?" Zhang Nan asked back.

"This... I agree with what you said, but it's very secret that there is really no good place here." Li Er agreed with Zhang Nan's statement, but he couldn't give Zhang Nan a good place, because Li Er used the most secret place himself, so it was impossible to draw a piece of Zhang Nan to do scientific research.

"Then the emperor will approve 10,000 Turkic prisoners for me. I will open a piece of land in the Qinling Mountains outside Chang'an City to work and reform in the mountains. Finally, I will put the Tiangong Department inside." Zhang Nan said seriously.

Seeing Zhang Nan's serious nonsense, Li Er felt like he beat Zhang Nan hard.

"Where do you need 10,000 Turkic prisoners? Is this the Ministry of Gai Tiangong? You just want to build an imperial palace in the mountain," Li Er glared at Zhang Nan. Li Er naturally disagreed with Zhang Nan's words for 10,000 Turkic prisoners.

"Then you can find a place for me, otherwise you will give me 10,000 Turkic prisoners. Your Majesty, please do it. Anyway, you have ordered the construction of the Ministry of Heavenly Works, and the Emperor's List will probably send it out. If all those people come in the end but have no place to work, I'm afraid you won't be able to hold your face." After Zhang Nan said that, he stood aside and stopped talking, which was like if you didn't give me land today.

"There are not ten thousand Turkic prisoners, and at most one thousand will be given to you. It's so great. Do you want to love? Don't let it down." Li Ershu waved his waves and signaled that there is no discussion on this matter.

"I really can't give you more?" Zhang Nan asked.

"It's gone, do you think the Turkic prisoners are ants? They are everywhere? You are still the director of the Tang Dynasty Labor Reform Bureau. I don't know how much you have left in your hands now?" Li Er asked.

Zhang Nan naturally knew that although there were many of these 100,000 Turkic prisoners, at least 80,000 were scattered to the border to build the city wall by Li Er. Li Er was not a charity and did not want these 100,000 Turkic prisoners to eat the food of the Tang Dynasty for nothing. Most of them were sent around Chang'an City to build roads and open land for the people of Chang'an City. The labor reform bureau is actually less than 10,000 Turkic prisoners left.

Li Er didn't want Zhang Nan to take a look. All these Turkic prisoners were eliminated. Otherwise, what kind of disaster would happen to the prefecture around Chang'an City? These Turkic prisoners would have to go to the post-disaster reconstruction.

"One thousand is just one thousand, then I will move the Tiangong Department to the Qinling Mountains. The emperor has built it up and invited you to have a look." Zhang Nan looked like he was doing good and was so obedient that he looked so angry that he saw Li Er was very angry, but he had already decided on this matter and could not change it even if he wanted to.
