Lu Qing's return brought a storm to the territory of Dengzhou, and all the merchants who were going to go to Silla, Baekje or Wa Kingdom found Lu Qing and them one after another, hoping to team up with them, after all, if they took the new route, not only could they save a lot of time, but also the cost would be nearly doubled.

However, it is a pity that according to the original agreement, this new route is under the management of Qi Wangfu, so the chart of the route has been handed over to Li Su, all the merchants who want to take this new route must go to the palace to register, and then divide it uniformly, and then lead the way by Lu Qing and the people they sent to assist, of course, the merchants have to charge a certain fee when they sign up, after all, in order to open up this new route, Li Su can pay the price of two new ships, and it is not his character to not want to recover the cost.

In addition to the shipping routes, the two government-run shipyards are also surprisingly popular. After the sea trial, although Lu Qing and they found some small shortcomings on the two new ships, but this can not hide the huge advantages of the two ships, because these two ships are pointed bottom boats, plus the design is reasonable, so the center of gravity is under the water, in this way, although the draft of these two ships is deeper, but it is more stable, and the resistance to wind and waves is also stronger. In addition to being stable and safe, the speed and operation of these two ships are also stronger than the previous ships, so with the spread of Lu Qing and them, these two new ships have gradually been recognized by many maritime merchants, and they have gone to the official shipyard to order, in order to meet these crazy orders. Not only did the civilian shipyard begin to expand, but even the military shipyard also divided some craftsmen and began to build two new ships under orders.

Taking advantage of this opportunity, Li Su simply integrated the shipbuilding industry in Dengzhou and established the Shipbuilding Industry Association, into which all shipyards that wanted to obtain patents for the construction of new ships should join it. All shipyards are uniformly naturalized and distributed, and after this round of integration, all shipbuilders and resources in Dengzhou will be maximized. It also made Dengzhou's shipbuilding industry start the first major outbreak in history, and dozens of Galen ships and Fu ships of various sizes were produced in just a few months.

Originally, the president of the shipbuilding industry association wanted Yifan to be the chairman, but she was busy trying to make a steam engine. And from time to time, he also had to help Yuan Tiangang and Li Chunfeng do some tests and calculations, so he was so busy that he didn't even have time to take care of the civilian shipyard under his name, let alone deal with the affairs of the Shipbuilding Industry Association.

In the end, in desperation, the president of the Shipbuilding Industry Association handed over to Wei Heizi, after the design of two new ships, Wei Heizi has slowly established his authority in the Dengzhou shipbuilding industry, coupled with the support of Li Su, he also recruited a group of skilled shipbuilding craftsmen, and through Li Su's instructions. A ship design institute was set up to specialize in the study and improvement of new ship types, and the patents for two new ships were hung in the name of this design institute, so all shipyards and sizes in Dengzhou had close ties with it, and it was also expected that he would serve as the president of the shipbuilding industry association.

In addition, having Wei Heizi as the president has another advantage. He was originally an official in Li Su's palace, and if he was appointed, it would also be convenient for Li Su to control the entire shipbuilding industry, after all, the shipbuilding industry occupies a key position in Li Su's plan, and it can only be in his own hands. in order to make better use of it.

After the caravan in Dengzhou was familiar with the new route, Lu Qing and the others said goodbye to Li Su, saying that they wanted to go back to the south to do something. They were originally merchants from the south, and it was normal for them to go back now, so Li Su did not stop them, and set up wine in the palace to see them off. At the banquet, Lu Qing and others said that after they went back to finish things, they would come back immediately, and they were likely to be stationed in Dengzhou in the future, which was an unexpected joy.

After sending Lu Qing and them away, Li Chunfeng also had to say goodbye, the summer was about to pass, and his vacation was almost over, so he naturally had to prepare to return to Chang'an early. With the help of Yuan Tiangang and Zhao Yifan, they have sorted out a set of methods for calculating latitude and longitude using celestial bodies, and the whole complex calculation process has been simplified a lot.

Therefore, after Li Chunfeng returned to Chang'an this time, he not only had to build the observatory that he had already said last time, but also had to design the working principle of the sextant, which was a very arduous task, but fortunately there were also many talents in Chang'an City who were proficient in astronomical arithmetic, and Li Chunfeng did not have to worry about not having helpers, and he also assured Li Su that although there were difficulties in the development of this sextant, as long as he was given a period of time, he would have the confidence to develop it.

For Li Chunfeng's guarantee, Li Su is naturally very happy, as long as he can get it out, as for the time, anyway, he is only fifteen years old this year, and there is time to wait.

Today is the day Li Chunfeng left, Li Su dressed up in casual clothes, and only brought a few guards to see him off, and Yuan Tiangang and Zhao Yifan were naturally among them. It's just that for some reason, Yuan Tiangang and Li Chunfeng are both in poor spirits, as if they didn't sleep well yesterday.

Li Su and Li Chunfeng raised their glasses together, and after drinking the send-off wine, Li Chunfeng strode up to the bow of the boat, turned around and arched his hand: "Everyone, please go back, Chunfeng will leave!" ”

Li Su and the three of them also returned the salute, and said in their mouths: "Treasure and cherish! ’

And Li Chunfeng also waved his hand again and again, until he watched the three people on the dock getting smaller and smaller, and finally even the entire Dengzhou Port slowly disappeared into the sea level, he sighed, although the sea breeze was very strong, but he did not enter the cabin, but looked at the birds on the sea, remembering what Yuan Shi found him to talk about last night.

"Chunfeng, do you remember when we first met His Royal Highness King Qi, His Highness asked me to meet him?" Yuan Tiangang frowned tightly in the candlelight, as if he had thought of some unsolvable problem. Tomorrow is the day Li Chunfeng leaves, and tonight Yuan Tiangang is going to talk to Li Chunfeng, and at the same time he wants to tell the other party about a difficult problem that he has been unable to understand these days, and ask him to help him calculate.

"Well, Master Yuan, I was also a little strange that time, with your attainments in physiognomy, how could there be a face in this world that could not be seen through, presumably Master Yuan had something to say at that time, right?" Li Chunfeng sat next to him and asked while making tea.

"Actually, I'm not lying, I really can't understand the fate of His Royal Highness King Qi!" Yuan Tiangang smiled bitterly, shook his head again and again, this is the first time he has encountered such a situation.

"What, this...... Is this actually true? Li Chunfeng was also startled, his always steady hand shook slightly, and a few bits of tea fell on the table.

"Well, His Royal Highness King Qi's face is full of antiquity, on the surface it looks like a rich and noble prince, but if you look closely, it is indescribably expensive everywhere, and I also see something in him!" Yuan Tiangang smiled bitterly, it was the kind of thing on Li Su's body that made him puzzled during this time, and even decided to stay in Dengzhou and observe the changes in Li Su's life at any time.

"Master Yuan, what is there on His Royal Highness King Qi?" Li Chunfeng asked curiously.

"Ninety-five!" Yuan Tiangang's face suddenly turned pale, and he said a name that made Li Chunfeng stunned.

"This ...... How is this possible? Li Chunfeng stood there for a long time in amazement by this name, and finally suddenly his legs weakened, and he suddenly sat down on the stool, still with an incredible expression on his face.

The so-called Ninety-Five Qi, this is a physiognomy statement, which is very complicated to explain, but to put it simply, there are only two people in the entire Tang Dynasty who have this kind of momentum, one is His Majesty Li Shimin, the current emperor, and the other is his successor, that is, the next Emperor of the Tang Dynasty. It is said that Li Su is Li Shimin's son, and it is normal for this kind of ninety-five qi to appear on his body, after all, he is one of Li Shimin's favorite sons, and he is very likely to inherit the throne. However, the reason why Li Chunfeng was so shocked was naturally for his reasons.

"Master, didn't you say last time that in addition to Your Majesty, the other one who has the Qi of Ninety-Five today is His Royal Highness the King of Jin, but now why does His Royal Highness the King of Qi also have the Qi of Ninety-Five, is there actually two heirs to the throne of the emperor?" After Li Chunfeng was shocked, he hurriedly asked with an anxious face, this is a major matter related to the fate of the world, and he can't be negligent at all.

"I don't know about that!" Yuan Tiangang smiled bitterly, "I have been thinking about the reason for this matter for this time, but after thinking about it, I only thought about two possibilities in the end, the first one may be that my physiognomy is wrong, and the other is that my physiognomy is correct, but this consequence is too terrible, I would rather my physiognomy be wrong!" Yuan Tiangang said this, with a painful expression on his face.

"Master Yuan, what do you mean to say......" Li Chunfeng is also a smart person, and immediately thought of the meaning of Yuan Tiangang's words, but when he thought of that kind of consequence, he couldn't help but have a cold war, could it be that my land of China has just been peaceful for a few years, and it is going to fall into war again?

In fact, the meaning of Yuan Tiangang's words is already very clear, if his physiognomy is correct, then in the eyes of him and Li Chunfeng, the only possibility is that Li Su and Li Zhi will both become emperors in the future, but there is only one throne in the Tang Dynasty, how can there be two emperors? The only explanation for this situation is to turn one throne into two, that is, the Tang Dynasty was divided into two countries, Li Su and Li Zhi each sat on the throne in their own countries, but as the so-called heaven has no two days, there are no two masters of the country, in order to compete for orthodoxy, the two countries will definitely fight endlessly, and then I don't know how many people will be displaced in this world, and reproduce the tragic situation at the end of the Sui Dynasty.

"Oh, that's not right!" Li Chunfeng, who was immersed in deep pain, suddenly thought of something, and immediately woke up and said, "Master Yuan, based on my estimation of the fortunes of the Tang Dynasty, in a hundred years, my fortunes of the Tang Dynasty will only get stronger and stronger, and there seems to be no sign of division?" (Your support is my biggest motivation.) )
