On the way, Sikong Nan wondered and asked:

"General, everyone else is gone, why did you come out so late?"

"Why, Ben Jiang won't come out again, don't you want to rush in and fish Ben out."

Sikong Nan laughed:

"I've thought about it, but who let this be Princess Lanyuan's mansion, and I don't have the courage to do this. But general, what are you doing in the mansion, you don't seem to remember what the general has to do with the Xuanting Marquis. ”

Bai Liyan (Wei Xian) smiled inexplicably:

"The secret of heaven must not be revealed, it is not beautiful to say too much. Let's go, go to the place where Qi Mo and his son are staying, and there are still some things to explain to his father and son. ”

Qi Mo and his son lived in the official post in the east of the city, and the three conditions for exchanging the method of steelmaking could not be transmitted back from the headquarters of the Gonggong faction at the end of the first month at the earliest, and it was really difficult to make a conclusion whether it would succeed or not.

Tomorrow he was going to leave for Yongxing River to prepare for the construction of the city, and Bai Liyan was worried that Qi Mo and his son would not find him for a long time, and they would fall into Xihuan's trap, so it was necessary to inform them to avoid trouble.

Not long after Bai Liyan left the Xuanting Hou Mansion, Princess Lan Yuan came to the boudoir of the Lord of Qiao County, and saw that she was embroidered with white silk with her head down, and the two pink delicate lotus flowers had begun to take shape.

"Fu'er, how is this General Wei, but you like it?" Princess Lan Yuan asked with a smile, sitting next to Lord Qiao and coaxing her.

"Mother is really, she knows her daughter's thoughts, but she still wants to make her daughter ugly, what if General Wei is ugly." Lord Qiao squirmed, his cheeks flushing pink.

Princess Lan Yuan disagreed, took out the bag sent by Baili Yan, and took out the crystal in it:

"Fu'er, look, this is a gift from General Wei to your father, see it, General Wei has taken a fancy to you."

"Mother......" Lord Qiao was panicked, and when he heard that Baili Yan liked her, he covered his face and twisted it for a long time in shame.

At dusk, after visiting Qi Mo and his son, Bailiyan returned to Yicaotang. Chunrou and Chunfang have already packed their bags, and even Bailiyan's clothes have been prepared several sets.

"General, has the county lord seen it?" Chunrou asked carefully, extremely flustered in her heart, very worried that Bai Liyan would snub her from now on.

Bai Liyan smiled indifferently, knowing what Chunrou was thinking, she hooked her chin with her hand and said:

"What, are you still worried that your husband won't want you?"

"What's the matter, Chunrou is worried that she will not be as beautiful as the county lord, which will make the general disgusted."

"Yes, Lord Qiao is indeed a beautiful country, but compared to the two ladies, each has its own merits."

Chunfang asked at this time:

"Lord Qiao is more beautiful than my sisters."

Bailiyan pinched her little buttocks, and the next moment she hugged her into her arms:

"There are many interpretations of beauty, some of which can only be viewed from a distance and cannot be blasphemed, while some of which can be tasted by men and women, and these two beauties cannot be compared, and how can they be compared."

Chunfang didn't know what to mean, Chunrou pouted and shook her head:

"My husband is really flamboyant, obviously greedy for my sister's body, but he still has to say such an unfathomable thing, I am really ashamed."

Bailiyan laughed:

"In addition to the love between men and women, the joy of fish and water is the joy of life, if you can only watch it from a distance, it is not a pity. Okay, I'm going to leave the city tomorrow, and I'm going to have a good night's rest for my husband tonight, I'm afraid that I will rarely be able to get close to the two ladies in the future, and the two won't blame the husband. ”

"The general is burdened with a heavy responsibility, how can Chunrou and her sister even cause the general to indulge in the gentle township, Chunrou and her sister still know these truths."

Chunrou's knowledge made Bai Liyan feel a little relieved and happy, and I hope that Gongsun Yue's hand has not touched the two of them.

Early in the morning of the second day, Su Hong got a carriage, and the second daughter took the fine soft carriage all the way out of the city.

There is an unnamed village forty miles east of the army camp in the Yongxing River, there are more than 400 households living at the earliest, after the army enters the Yongxing River, the Qin Wang and magnates from all over the country are accompanied by concubines and maids, most of these families are placed here, and the village is also named Wang Dependents Village.

In order to improve the living conditions, these Qinwang magnates also recruited craftsmen from the tomb to overhaul the house in the Wang's Dependent Village, and in June and July, they actually built no less than seventy or eighty large and small courtyards, as well as thousands of houses, and now nearly 6,000 people have moved here, in addition to nearly 2,000 people in charge of the security of each family, just like the scale of a small county town.

Bai Liyan also planned to let the second daughter live here temporarily, so that she could have a place to stay, and transferred fifty young men to the two of them as guards.

These teenagers were all forcibly recruited from last year, the youngest was only thirteen or fourteen when they came, and the oldest was only sixteen, and they were simply sent to serve as cannon fodder.

Most of these children have no combat effectiveness, and they were used by Zhao Xun as a husband on the second line in the early days, and when the front line is at its most intense, the teenagers will also be pulled to the battlefield, and there are nearly eight hundred teenagers under Baili Yan, most of whom are only fifteen or sixteen.

Let the young man act as the second female protector, first, the young man is ignorant of the world, does not know much about the affairs of men and women, and cannot be like a veteran wanderer who has evil thoughts and does things that are not tolerated by heaven.

Second, Chunrou and Chunfang are older than them, and their minds are more mature, and it is not a big problem to control children. Third, although he is a young man, he has seen blood, and he does not necessarily suffer if he is fierce.

When the second daughter was settled properly, it was already dark when he arrived at the Yongxing River camp, and Zhao Xun's big tent was brightly lit, and he was finally negotiating with the generals on the construction of the city. In addition, there is a military engineer who is proficient in construction art to explain on the spot, a huge construction picture is painted on a white cloth, and it is hung on a hanger for everyone's reference.

"Wei Xian has seen Zhao Shuai."

"Wei Ce should have come just in time, Ben Shuai is discussing with the generals about the construction of the new city, and you should come and attend." Zhao Xun said, and the generals cast their eyes one after another.

"No!"

Most of the construction of the city is step-by-step, using the old map to set the new city, using the old city construction map, according to the topography and landform to make small modifications, according to the field conditions and the construction of the new city, so after the field investigation of the new city site, the drawing of the drawing does not take too much time.

The new city built by the Guantang Canal is 16 miles long and two or three zhang high, and the scale is not large, and it is not a big problem to use the terrain and mobilize 200,000 to 300,000 people and tens of thousands of horses and animal power to build the new city within three months.

Xincheng will take advantage of the geographical advantages of the Yongxing River and the Guantang Canal to dig moats on the north and east sides to connect the Yongxing River and the Guantang Canal, so as to prevent the Yongxing River from being breached and the rebels can still contain the rebel forces after the Yongxing River defense line is breached.

The creation of the picture cannot be said to be fine, but can only clearly express the main functional structure of the new city, and cannot really feel the scale and full vision of the new city. Moreover, all the strong cities in the world have their own weaknesses, there is no fortress that cannot be attacked, only unexpected accidents.

The new city is located in the Guantang Canal, with the Yongxing River as a barrier in the west and the Guantang Canal in the south, surrounded by water on both sides, and the focus of the Black Turban Army's attack comes from the west side. But in this way, no matter which direction the enemy soldiers come from, they may become a lonely city.

The main purpose of the moat is to increase the difficulty of the siege, and it also serves to prevent the attack of caves and digging into the walls, and also to provide water for the castle.

The disadvantage is that once the enemy soldiers are besieged for a long time, it will be difficult to break through, but they will fall into a dead place. Moreover, the moat is not omnipotent, as long as you are careful, you can fill the moat at any cost in wartime. Even Genghis Khan used trebuchets to throw stones day and night, filling the city with stones.

Therefore, Bailiyan does not advocate digging a moat when there are already two water areas. If it must be dug up, a large dry dock should be excavated to the north of the new city, and the dry dock should be used to step up the production of large warships.

The Jin State occupied the eastern county of Jiangdong, and the shipbuilders along the local coast were all relocated to the Jin State, so that half of the shipbuilding capacity of the Xian State was lost, and it was imperative to restore the shipbuilding industry and consolidate the fortune of coastal defense.

First, it can enhance the combat power of the navy, second, it can escort the transportation, and third, there is no dry dock technology at present, and shipbuilding is built from the bottom up on the ground. If a dry dock is used, it can be constructed at the same time after the keel is laid.

Not counting the keel setting time, the entire shipbuilding cycle can be shortened by at least half. Especially for the construction of large vessels, dry docks are a must-have infrastructure.

Back then, Master Wu Shu built huge warships for the Jin army, and each large ship took six years to complete, and at this scale, it was not the limit that a wooden warship could reach.

As technology evolves in the future, larger wooden warships may also appear. The reason is not that the technology is not advanced, but that the shipbuilding process of Wu Calculation has reached the bottleneck limit of the current technology, even if there is an improvement, it must wait until other advanced technology progress, in order to have a longer development, for the time being, the development of dry dock is an inevitable choice.

The dry dock will put the whole ship into the trough, and when it is finished, open the water door to allow the ship to float itself out of the dock. Nowadays, the biggest technical problem in the development of dry docks lies in the water gate and drainage method.

Modern times can rely on electric power, hydraulic transmission and other power units to drive the closing of the gate, and finally drain the water through a water pump. No, there are no automations available, so the opening, closing and draining of the water gate will be a test of the current technology.

If the moat is replaced by a dry dock in the north of the city, a dock that is several zhang or even more than ten zhang wide is safer than the moat, and at the same time can also serve as a port and garrison the navy for a long time, further consolidating the water defense of the new city.

The moat will be dug again after the completion of the new city, and Bailiyan estimates that it will not be too late to discuss it when the Ligong faction has a reply.

The meeting lasted until late at night, and the opinions put forward by the generals were also varied, and even the construction officials were once asked, and the most acute question was the flood.

The new city was built on the high ground of the Guantang Canal, but the Guantang Canal was not within the city wall of the new city, if the enemy army attacked the Yongxing River and occupied the Guantang Canal, built a dam and dug a waterway in the Guantang Canal, and flooded the new city.

Nowadays, the vast majority of the city wall is earth rammed, not covered with bricks, big water blisters for three days, it may collapse under the strong attack, not to mention the huge amount of water in the Guantang Canal, and the south wall is very likely to be unable to withstand the impact. This problem also aroused Bai Liyan's great concern, he didn't expect it, but he had a way to deal with it.

Flooding the city with water is extremely harmful, and the victims are often seven or eight out of ten.

During the site visit to the Guantang Canal, the canal was widened and extended on top of the original river channel, and a dam was installed to store water to facilitate the diversion and irrigation of inland farmland.

To avoid Daigo empowerment, it is not advisable to either scrap the canals or raise the foundations of the new city. The only feasible way is to change the south gate to the water gate, dig a ditch from the Guantang Canal to bring water into the city, and then from the west gate to the Yongxing River, so that the water from the Guantang Canal can flow back into the Yongxing River.

At the same time, the pond and canal were dug in the city to increase the water storage space in the city, and at the same time, it can also provide a large amount of water for smelting and production.

The most fundamental measure once and for all is to expand the outer city in the future to include the Guantang Canal, so that the hidden dangers can be completely solved.
