When Sun Xiangfu and Yang Shunshui sailed the fast boat to Qujiangchi Wharf, Zhang Gongjin was already waiting here, and he didn't even go back to his house to confess, so he rushed over directly, and only his coachman went to Goguryeo with him.

"Zou Gong, these two people are Yang Laohan's nephews, one is called Yang Ming, the other is called Yang Jie, they take turns to operate the boat, at most five or six days, I guarantee that you can go to Laizhou, after you go there, you can stay by your side and listen to it!"

"You can get to Laizhou in five or six days? That's a good job. ”

Zhang Gongjin looked at the two of them with approving eyes and said, "Now that the military situation is urgent, I won't say much about it, just tell me how many people and horses you have in the sea off Laizhou, how much combat effectiveness is, and how the old man wants to contact them." ”

Zhang Gongjin is a person who understands boats, after getting on the boat, he felt it a little, and he knew the sharpness of this ship, and the current situation is that he arrived in Goguryeo earlier, and the space that can be operated there is more, yes, and he is not polite to Sun Xiangfu.

Sun Xiangfu thought for a while and replied, "There are about eight hundred people, all of them are capable people, and they are all Wanshi's new water ships, a total of ten, that kind of ship Zou Gong should have seen in the shipyard before, and I won't say much about the function." The ships are well armed and equipped, superior to the warships of the imperial court, and at sea, you can almost ignore the naval forces of other countries, and use them to ensure the supply and evacuation of our army at sea, there is no problem at all. ”

There is a natural difference between sea operations and land operations, ships and weapons are more advanced, and they almost occupy an overwhelming advantage, and the Wa and Goguryeo naval armies, which have not yet introduced various technologies to Li Tang on a large scale, are like children facing adults, and basically have no strength to resist head-on.

Moreover, for more than a year, Zhao Long and the others have basically wandered around the peninsula and the waters of the Wa Kingdom, and they have a considerable understanding of the sea conditions over there, and after Zhang Gongjin meets with them, they should be able to formulate many feasible strategic plans according to their own advantages.

"I thought it was a very difficult task, but I didn't expect that Zhengming would have a surprise for the old man, who could ensure the supply and evacuation of the army, and the battle of Goguryeo would be much easier to fight."

After listening to Sun Xiangfu's introduction, Zhang Gongjin was immediately full of confidence, and Sun Xiangfu hurriedly asked people to take pen and ink paper, and wrote a letter to Zhao Long and others on the spot, to the effect that all their actions should be under Zhang Gongjin's command.

"Zou Gong, the matter of Goguryeo, if there is something to do, then do it, if you can't do it, there is no need to trap yourself over there, you know, to occupy Goguryeo, you still have to mobilize my army of the Tang Dynasty, and there are few people in the Tang Dynasty, in order to meet their own consumption, they need to strengthen labor productivity, if they can establish a route on the sea to transfer the population from Goguryeo to the Tang Dynasty, so that the people who originally contributed strategic resources and tax output to Goguryeo will contribute strategic resources and tax output to our Datang, they are weak and I am strong, this is also a victory."

"The old man knows this, the old man has Gao De in his hands, and when the time comes, he will use him to transport the women, children and children who are unable to contribute to the war to Laizhou by sea, leaving only the young and strong soldiers to fight with Yuangai Suwen, in this way, those soldiers whose families have evacuated to Datang will have no way to retreat, and they will definitely fight bravely to kill the enemy, in order to cause losses to Yuangai Suwen, even if they are finally defeated, those remnants of the Gao clan can only take refuge in my Datang, and the outcome you know."

"It turns out that Fu Gong has already made a plan, so I can rest assured, so I will arrange things for people in Laizhou and other places, for the population, we are as much as possible!"

"The old man knows that you are full of plans to make a fortune, and what you lack is labor to realize it, so the old man will not make a big killing over there, there is nothing else, you can go back first! The old man went to Goguryeo earlier, and he could get more people back for you. ”

After the ink was dry, Zhang Gongjin urged Sun Xiangfu to get off the boat, Sun Xiangfu hugged his fists and said goodbye, and watched the clipper leave on the shore, and his heart was full of emotion.

The reason why Sun Xiangfu cares so much about the population of Goguryeo, in addition to the demand, is because he sees that the population is the foundation of Goguryeo, it is the country with the second largest population in Asia in this era, with more than one million households, and the number of young and strong men is five or six hundred thousand, it can be seen that its total population is at least five or six million or more, even if the Tang Dynasty includes the Turkic and Northeast four tribes, it is only about three million households, 10 million people, and they fight a war of attritionIt is easy to hurt the muscles and bones.

There is another aspect, after the population of Goguryeo arrives in the Tang Dynasty, there will be no discomfort at all, first of all, the special race is the same, and the other one, they have already entered the agricultural society, many people still speak Chinese, and the cultural level of ordinary people, even not lost to the Han people of the Tang Dynasty, is a kind of high-quality population that can be used as the main force of production directly, Sun Xiangfu certainly does not want to let go.

After returning to the house, Sun Xiangfu sent a letter to Wei Zheng, asking him to go to Xingfu Village to make glasses, and by the way, talk to him about the affairs in Shandong, as the representative of most of the small and medium-sized landlords in Shandong, he can provide a lot of help to the people who accept Goguryeo, however, Sun Xiangfu does not intend to let these families in Shandong consume the population that moved from Goguryeo, because it is too close to Goguryeo, and the people may want to escape back. The people of Guanzhong are now facing the transition to industrialization, and a large amount of originally developed land needs to be cultivated, and it is most appropriate for the Goguryeo people who are familiar with agricultural affairs to supplement it.

The next day, the entire Chang'an City was more lively, because it was the day of the imperial examination.

The gong passed the list, and the officials who announced the decree, wearing brocade red robes and tall horses, looked for the top three candidates in each subject in various places in the city, and the chickens and dogs jumped all over the city, and the cold wind in winter could not stop the people of Chang'an from watching the lively mood.

The top three candidates in each subject have become famous in an instant, and when they enjoy the envious and jealous eyes of the people of the city, their hearts are also excited, the court let them be so beautiful, they dare to repay the court with their own strength?

Something like the imperial examination, at the beginning, will play a very good role in the country and society, because at the beginning, people's minds are often relatively simple, and over time, the performance will become a vanity fair, so that countless people rise and fall in it, fortunately, it is still just the beginning.

Although there was no situation like in the Song and Ming dynasties to catch sons-in-law, but these champions, listers and tanhuas who were able to achieve good rankings and win the favor of the emperor all came into the sight of the family magnates.

The Qionglin banquet was arranged for tomorrow, so Wei Zheng, who would hold a conference tomorrow in the Ministry of Law for the children of the Ming Law Division, was free today, and after the dispersal of the dynasty, he took a fast boat with Sun Xiangfu, and it took less than an hour to appear in Happy Village.

"The relocation that Shicai talked to Wei Shangshu about on the ship is related to the future development plan of Guanzhong, and it is good to ask Wei Shangshu to help as much as possible!"

"Loyal to the country, the old man will not be left behind, but let the old man give up an old face to help you, should you also repay the old man?"

"Isn't this the exclusive making of glasses for you?"

"This doesn't count, it's what you promised the old man before."

"Then you just say, what counts."

"The old man knows that you wrote a management statement for Zhenglun of the Ministry of Commerce, so that he immediately found the management direction of the Ministry of Commerce, although the Ministry of Law managed by the old man, although it is not like the Ministry of Commerce from scratch, but it is also a new department with different powers from before, Zhengming, is there no management statement written to the Ministry of Law like written to the Ministry of Commerce?"

Sun Xiangfu knew early on that Wei Zheng was waiting for him here, so even if he had already written Chen Tiao yesterday, he didn't hand it over to him as soon as he saw him, and after he put forward the conditions, he took out a tie from his arms and said, "In this way, this favor owed to you can be repaid in the future." ”

Seeing the thick tie, Wei Zheng was overjoyed, and he didn't care that Sun Xiangfu had a plan earlier, so he hurriedly took it over and thanked him, "It's all for the sake of state affairs, where there is any unkindness." ”

Then, he couldn't wait to squint his eyes and open Sun Xiangfu's codex.

In order to help Wei Zheng make reading glasses, Xingfu Village specially opened a kiln to fire convex lenses of different thicknesses, Sun Xiangfu saw that Wei Zheng was fascinated, so he went to the cave and chatted with Han Shaowen, the chief technical engineer of firing glass.

"What progress has been made in microscopic research?"

"Not yet, just with concave and convex lenses, unless it is made very large, it is possible to increase the magnification to more than 80 times, if you want to make the microscope you need more than 160 times, you need to arrange the internal placement of each group of lenses very accurately, that is to say, you can be a big guy, at least big enough that people can go in, to the point of manual adjustment, and you may need to adjust the installation repeatedly, because there is a little bit of a small angle problem, the whole thing is not established."

Sun Xiangfu knows that scientific and technological products need very accurate mathematical support, if all the refractive angles of imaging can be calculated in advance, then only need to be constantly adjusted during the production to make the angle of the lens accurate inside.

He handed over the task of calculation to Li Chunfeng to see if he could calculate all the data in advance, he was a little biased himself, he didn't like mathematics, and it was difficult to do this aspect of things, even if he didn't want to do it.

"Well, you test more, study more, don't be afraid of the problem of cost consumption, and after the opening of the glass workshop in Weinan next year, we can put a small amount of dressing mirrors on the market to sell and make money." Externally, ten cellars of glaze may not be able to fire a mirror, maintain its high price in the market, scarce status quo, a few years later. ”

"Knowing the master, the members of our group are not focused on making dressing mirrors with no technical content, everyone is working hard to make what you said, which can magnify more than 160 times and see some things that cannot be seen with the naked eye."

"Well, it's good to have such motivation, doing technical research, boring is inevitable, you must have a love of inquiry, in order to persevere, as long as this thing is made, your Han Shaowen's name will definitely be recorded in the annals of history and passed down through the ages."

According to the annals, everyone thinks about things that have been passed down through the ages, but these things seem to be relatively far away from reality, just a little fantasy, and Han Shaowen returned to reality.

"Master, you can make convex lenses, I will divide dozens of thicknesses, make a batch first, and after Wei Shangshu chooses it, I will make a few glasses of the same thickness for him as a backup."

Not long after, Sun Xiangfu took dozens of glass lenses and let Wei Zheng test them in front of him.
