"What's so bad about going, is it because their national strength is too strong? It's okay, we're going to do business, not to fight, you don't have to worry about Qingquan. After Li Er finished speaking, he waited for Zhang Nan to give him a definite answer.

"It's not because of the country's problems, the emperor knows the difficulties of navigation." Zhang Nan said seriously.

Li Er shook his head, after all, Li Er had lived for so many years and had no experience in sea warfare, so he was not clear about the dangers of long-term sea voyages.

"Sailing on the sea is not as simple as everyone thinks, especially if you can't rely on the shore for a few months, it's even more difficult, we walk on land, if you get lost, you can identify the direction by the sun and stars, if it's cloudy, we can rely on other things to identify the direction, but navigation is not good, if you encounter rainy weather, how can we identify the direction, if there is no clear direction, isn't it a lifetime can not reach the destination." Zhang Nan said.

Seeing Li Er's thoughtful expression, Zhang Nan continued to say while the iron was hot.

"And our big ships sail now, mainly relying on manpower and wind to travel, but the sea will encounter wind and waves, a wave can even break the ship apart, if it encounters a storm, the manpower ship is simply difficult to move an inch at sea, if you encounter these things, it will undoubtedly prolong the sailing time, the longer you stay at sea, the greater the risk. It is not an exaggeration to say that sailing is a life of nine deaths. Zhang Nan said.

After Li Er heard this, he nodded, but Li Er still didn't want to give up the idea of going to sea by himself.

"Your Majesty, the minister is not afraid of death, and I hope that the emperor can let the minister go to sea and bring back these things." Niu Jinda stood up and said.

Zhang Nan looked at Niu Jinda with a fearless look, and suddenly felt a big head, no matter when, there will always be warriors who are not afraid of death.

"General Niu, I admire your courage, but this kind of thing can't be solved without fear of death." Zhang Nan said.

"Alright, Qingquan, you just tell me what I should do to get these things. As long as I can get the things you said, ask for money for money, ask people for people, even if it is to start a war for this, I will not hesitate to do it. Li Erdao.

In the past, as long as Li Er said that he would use troops wherever and where, there would definitely be 80 percent opposition voices in the court, and 20 percent of the voices of support were Li Er's loyal supporters of the war maniac.

But this time Li Er said that he was going to start a war, and the court was surprisingly quiet, even the Yanguan group, which was most opposed to the war in the past, was collectively silenced, and there was no opponent, which made Zhang Nan a little surprised.

"Your Majesty, the minister still said the same thing, engage in scientific research, and when the steam engine is made, we will be able to open the Age of Discovery." Zhang Nan went around and around, still hoping that Li Er could agree to his strategy of rejuvenating the country through science and technology.

"Okay, tomorrow, I will send an imperial list to the major state capitals of my Datang, and recruit all the craftsmen who are good at tactfulness in my Datang. From now on, I Datang Xinli a "Heavenly Work Department" This department is specially used to invent Karakuri and improve Karakuron, Qingquan, are you satisfied? Li Er finally compromised in front of potatoes, corn and sweet potatoes.

"Satisfied, satisfied, of course the minister is satisfied, but the minister still wants two people to assist the minister in establishing this Tiangong Department." Zhang Nan saw that Li Er agreed, and immediately said with a smile.

"I said, if you want money to give money, you want someone to give people, you say, who do you want?" Li Er is also very happy now, as long as this Tiangong Department is established one day earlier, then he can find these foods with a yield of thirty stones per mu one day earlier.

"Yuan Tiangang, the director of the Taishi Bureau, and Li Chunfeng, the chief bookkeeper." Zhang Nan said.

In fact, Zhang Nan took a fancy to these two people, and there was nothing else, mainly because both of them were Taoist priests, Zhang Nan thought that it was more convenient for these two people to learn chemistry, and if he gave them some simple chemistry textbooks, their receptivity would definitely be much stronger than others.

"Okay, from today onwards, the two of them will be under your control." Li Er said boldly.

"Wait, Your Majesty, the minister has something to do." Wei Zheng stood up and said.

"Oh? What is the matter with Aiqing, to put it bluntly, it is not that he does not agree with the establishment of this Tiangong Ministry. "Li Er still has a certain reason to think so, after all, Wei Zheng likes to go against himself every time, but this time Li Er doesn't plan to give Wei Zheng a chance to go against him, if Wei Zheng is unwilling, then Li Er can only use the imperial power to forcibly let this Tiangong Department be established.

"The minister very much agrees with the establishment of this Tiangong Department, after all, this is a matter that is beneficial to my Datang, as long as it is beneficial to my Datang, the minister will definitely agree." Wei Zheng arched his hand.

"Then tell me what you have to do." Li Er couldn't help but feel happy when he saw that Wei Zheng agreed.

"The minister dares to ask the emperor, the emperor plans to attribute this Tiangong Department to that department?" Wei Zheng asked.

"Naturally, it's the Ministry of Industry." Li Er said as a matter of course.

"The minister asked the emperor again, who is in charge of the Ministry of Works this day?" Wei Zheng continued to ask.

"Naturally, it's Qingquan, I think there should be no one except Qingquan who can run this Heavenly Work Department." Li Er said.

"The minister also thinks so, but the emperor, Lord Zhang is now from the director of the Labor Reform Bureau of Sipin, and he has a heavy position in the Ministry of War, if this Ministry of Heavenly Works is established, it must also be one of the important departments of the Ministry of Industry, and this person is also an important position in the Ministry of Industry and the Ministry of War, which is an unprecedented precedent." Wei Zhengdao.

In fact, Wei Zheng was also right, the Labor Reform Bureau of the Ministry of War, before the Turkic prisoners came, everyone didn't care about this department, but after the 100,000 Turkic prisoners came, everyone found out that this Labor Reform Bureau was so important, and this importance would continue.

Now that Li Er has established this Tiangong Department again, who knows if this Tiangong Department will become the next Datang Labor Reform Bureau.

Li Eryi thought that this was indeed the case, but he took down Zhang Nan, the director of the Bureau of Labor Reform, so grandiosely, Li Eryi couldn't find someone he trusted to put in this important position, and Li Er fell into a dilemma for a while.

"Your Majesty, the minister thinks that the emperor should give the position of the minister to someone else, the director of the labor reform bureau, after all, as soon as the Ministry of Heavenly Works is established, the minister will definitely be too busy, so I hope the emperor will find someone to replace the minister's position." Zhang Nan was worried about Li Er in a timely manner.

"Oh? It's really good that Qingquan knows the general situation so well, but I don't have a very good candidate for a while, do you Aiqing have anyone to recommend? Li Er asked.

"The minister thinks that Du Ruhui's second son, Du He can take over the minister's work, and during the time that the minister is in the Labor Reform Bureau, Du He has been helping the minister again, and Du He is completely competent for the operation of the Labor Reform Bureau." Zhang Nan continued to say, no matter what, Du He is also his apprentice, and Zhang Nanquan should be working for the benefit of his apprentice.
