In the middle of March of Chongwen 16, it has been more than ten days since Ling Yu put down the rebellion, the affairs of the Song Domain have been basically straightened out, the Tusi are now very honest, An Hongyi and others have also been escorted into Beijing by Ling Yu first, and the rebellious villagers have also been detained near Chengdu Mansion, and Ling Yu is also preparing for the preliminary matters of building the road together with Helianbing.

Since this rebellion started from the Song Domain, their plan was to repair the existing official roads from Chengdu Fucheng to the north, and the craftsmen brought by Ling Yu also developed cement through Ling Yu's guidance.

Specially from Chengdu Fucheng tried to repair the cement road to Xindu for a day, the effect is very good, this result made Helian Bing very happy, even praised Lingyu Dacai, where has he seen such a good official road before, before the Great Zhou Road, it is good to be able to tamp the road, it is easy to become muddy in rainy days, but the cement road is different, not afraid of water at all, which also makes Helian Bing more firm in the belief of building the road.

On this day, Ling Yu and Helian soldiers came to the camp to watch the local prisoners, today is the day to prepare for the big construction, after a period of preparation, the craftsmen brought by Ling Yu cooperated with the local craftsmen in Chengdu Prefecture, and produced a lot of cement on a large scale, so the two of them combined, felt that it was time to start building roads.

"Your Excellency, I'm going to bother you today." Ling Yu said with a smile.

"Hou Ye is polite, this is what this official should do, and thank Hou Ye for making so many good suggestions, the most important thing is to thank Hou Ye for developing this thing, if the official roads in Sichuan Province are like this road in the future, then there is no need to worry about any instability, once something happens, it will be much easier for the army to march." Helian Bing stroked his beard and smiled, thanking Ling Yu again.

"The governor is polite, and he is also entrusted by His Majesty to be loyal to the king." Ling Yu said politely.

Then, Helian soldiers didn't say much, let his subordinates allocate a group of prisoners, and Long Mingyuan, the general of the Chengdu Prefecture Garrison, led his troops to take care of them, and began to advance north along Xindu.

Since the official road of Chengdu had already been built, the new capital road was built directly to the north, connecting the prefectures and counties along the way, passing through Longanfu until the Songfan, and then building a road connecting the various Tusi in the Songfan.

The matter here is over, of course, the matter of road construction does not need Ling Yu and Helianbing to go to the front line to command in person, with Long Mingyuan leading the troops to take care of it, whether it is Ling Yu or Helianbing, they are very relieved.

Seeing that there was nothing to do, the two went back to Chengdu City, and went back separately in the city, as soon as Ling Yu returned to Xingyuan, his subordinates sent letters and holy decrees sent from the capital, the letters were naturally sent by Zhou Shaobin, and the holy decree was that Zhou Zhengxiong asked Ling Yu to make arrangements to return to Beijing as soon as possible.

After reading Zhou Shaobin's letter, Ling Yu shook his head helplessly, and said in his heart: "The matter of the airship was actually leaked by this guy who burned the cake, I really don't know how to explain it to Your Majesty when I go back." ”

"Xiao Ling, how is the design progress of the airship now?" Ling Yu thought about it and asked Xiao Lingdao.

"Master, there is no problem with other aspects of the airship, now the anti-gravity rune I said before has not been properly solved, I have been deducing for a long time, there has been no good result, I need to keep deducing various schemes, it will take a lot of time." Xiao Ling replied.

"Well, I knew it was going to be like this, this guy who burns the cake...... It's really ......," Ling Yu said helplessly to Xiao Ling.

"Master, if you really can't use the principle of a hot air balloon, wouldn't it be good to make one that can fly out first?" Xiao Ling came up with an idea.

"Hot air balloons? This is a different solution, then you can pick a hot air balloon that can be made under the current conditions, and modify the design for me. Ling Yu thought about it and commanded, hot air balloons are better than nothing, actual combat may not be very practical, but it can fly, observe the enemy's situation on the battlefield, and command artillery bombardment can be used, but it is far from the airship that Ling Yu expected.

"Okay master, I'll pass it on to you." Xiao Ling Dao, in just a few words, Xiao Ling had already selected a simple hot air balloon that could be made, modified it according to the situation, and transmitted it to Ling Yu.

Ling Yu took a brief look at this hot air balloon, in fact, it was similar to the simplest hot air balloon he knew in his previous life, but the fuel was changed to use spirit crystals to provide energy for the burning runes, which not only had a stable energy supply, but also controlled it very easily under the blessing of Xiao Ling's various spirit runes, and it was not difficult to manufacture, all of which were materials that Da Zhou already had. Let's play

Ling Yu was not in a hurry, this matter can be tried again after returning to Beijing, the most important thing now is to deal with the affairs of Shu according to the emperor's requirements, and then return to the court.

Ling Yu was busy dealing with the affairs of Shu here, and thousands of miles away in Beiping Mansion, the Zhao family, and Zhao Bohan were reporting the recent situation in front of Zhao Ritian.

"Father, after months of hard work, now we have been equipped with five thousand muskets in advance, but no matter how our craftsmen study, they have never been able to achieve the effect of the kind of musket made by Ling Yu, but it is enough for the time being, and the child has also invited a few Xiyi to come over as instructors through the relationship of the Qian family to train these soldiers, according to the Xiyi instructor, the musket array pays attention to uniform movements and indomitable courage, as long as it can travel within the range of the enemy's artillery fire, It is also possible to inflict a blow on the enemy, it is said that the soldiers of their country are like this, and their weapons are not much different from ours. Zhao Bohan reported.

"Well, Bohan, this matter is done well, but the matter of improving the musket is still urgent, you also know that the imperial court has more troops than us, even if it is to fight for consumption, we can't fight them, there were no muskets before, the combat effectiveness of our border army is stronger than that of the Beijing army, and now the Guards have initially formed combat effectiveness, we want to win, the weapons can't be too bad, don't the craftsmen have any good suggestions?" Zhao Ritian frowned, he still felt that the gap in weapons should not be too big, especially against the Jing army trained by Ling Yu.

"Father, the child also asked the craftsmen in the workshop, according to them, if you want to achieve the same strength as the guard, you must use more advanced level 5 materials, but this will cause the cost to be high, so the child did not order the manufacture." Zhao Bohan said, in fact, the craftsmen of Zhao Mansion had already given a stupid way to use fifth-level materials, but Zhao Bohan felt that the cost was too high and did not implement it, after all, it was difficult to equip more than 100,000 people, and if the cost was too high, it would be difficult, even if the Qian family was rich and rivaled the country, it was not easy.

"It's okay, our Zhao family and the Qian family's financial resources can still afford the fifth-level materials, you first let the workshop try to make some to see the effect, if it's really good, then make a batch too, and use it with this fourth-level material musket." Zhao Ritian thought about it and said, in order to equip a better musket, he was already planning to spend a lot of money.

"So the child will understand, and he will not disappoint his father." Zhao Bohan heard that his father had already decided, so he agreed.

"Well, Bohan, the training of the five thousand soldiers who were equipped in advance cannot be left behind, it is best to use these five thousand muskets to train more troops, and wait for the production of more muskets to come out, and they will have a certain combat effectiveness when they are equipped." Zhao Ritian nodded and said.

Zhao Bohan didn't say more, and went back to arrange it after agreeing, at this time Yan Zhongdao walked in from outside, he had been back for a few days, and he had also asked Zhao Ritian earlier, but as one of Zhao Ritian's right and left hands, he was also one of Zhao Ritian's most trusted people, so naturally he would not blame him, let him stay in Beiping Mansion to rest for a while, and wait for Beihu Wangting to solve the problem in the west, Mu Qingfang would definitely return to Wangting, and it would not be too late to visit at that time.

"Grandpa, my subordinates feel that the design of this musket that Ling Yu gave to Bohan seems to be a trap set by him, so that we spend a lot of money, material resources and time to make weapons, and in the end we can't beat his weapons." Yan Zhongdao said worriedly.

"Zhongdao, how can you not know what you are talking about, I have already seen through Ling Yu's clumsy plan, but what can I do, if we don't do it, we can't beat him, and there is still a little chance to do it, the situation has become too fast, and Beihu is also dropping the chain at a critical time, otherwise maybe we will have it done at this time." Zhao Ritian sighed, of course he could see what Ling Yu meant, but he had to do it.

As the strength of the Beijing army became stronger and stronger, the battle reports of several battles were sent to Zhao Ritian's desk, making him feel that he still had the power to fight, and if he didn't do it, he would only be wiped out.

"But, grandpa, even if we don't hesitate to make better muskets, then Beihu can't cooperate with us at that time, then we will be under a lot of pressure, and we will have to face the pressure of several border armies." Yan Zhongdao said worriedly.

"Hmph, I know very well what the combat effectiveness of those border armies is, all the border armies of the Great Zhou Dynasty are the strongest in our mountain navy, and I also let Bohan use the situation of mixing ordinary muskets and high-grade muskets, even if Beihu can't cooperate with us at that time, we only need to send these ordinary musket soldiers to deal with those border troops, and our elite still has to fight against the Beijing army." Zhao Ritian said disdainfully, he didn't look down on other border troops, he couldn't come from afar, and he wasn't afraid of being close before, not to mention the mountain navy after being reloaded with muskets, which gave him greater courage.

"When my subordinates were in Jingshi, I also heard Lord Zhao say that Ling Yu seems to have made a new weapon, and I heard that the power is still very great, and my subordinates are a little worried." Yan Zhongdao remembered the rumors he had heard before.

"Zhengkang also wrote to say this, that thing is called a psionic cannon, according to my understanding, it is a large psionic musket, and the Xiyi instructor we invited also said that thing, it is said that it is not only bulky, but also very slow, they are mostly equipped on sea ships, I have not heard of them used in land warfare." Zhao Zhengkang said with a smile, the Xiyi instructor he invited did say that because the history of this world is different, the artillery has not shown the grandeur of the king of war, not to mention Zhao Ritian, Xiyi himself is not very clear.

"Alas, since this is the case, I can only take one step at a time, I hope things will develop in a better way, my subordinates feel that we still have to find a way to get rid of Ling Yu, my subordinates have long said that this person is a big threat, but now that he is getting full-fledged, it is not as easy to cook as before, and he also has a powerful master, it is really difficult." Yan Zhongdao sighed, after several contacts with Ling Yu, Yan Zhongdao has been failing, and he is also highly concerned about Ling Yu.

"This matter is not in a hurry, presumably Mu Xian will make a move, she doesn't want the emperor's strength to be too strong, then she will have no hope of revenge." Zhao Ritian said with a smile, he was still sure about asking Mu Qingfang to make a move, even if Ling Yu was Mu Qingfang's nephew, but with Mu Qingfang's stubborn character, he would still make a move.

For Zhao Ritian, who personally directed the cannibalism between Zhou Zhengxiong and Zhou Zhengyun's brothers, his psychological grasp of Mu Qingfang can be said to be quite accurate, otherwise he would not have been so bold back then.
