At the beginning of the first month of the fourth year of Chongzhen, Liu Renyu's subordinates finished recruiting soldiers and trained them strictly according to the usual practice. In addition to asking the Du family to help transport grain and grass to Jinzhou in eastern Liaodong, Liu Renyu also did not forget to ship cement and steel bars to Jinzhou, in addition, he also specially ordered Ma Tianjun to allocate 3,000 fat sheep that were pickled and dried, and were escorted to Jinzhou City in Liaodong by a special person to store them first, and then use them after he led his troops into Liaodong.

After finishing these things, Liu Renyu began to arrange his marriage with Du Ruonan.

This time to handle the marriage, because of the previous wedding with Sun Yuyun, Liu Renyu and his subordinates are familiar with it.

Recruitment, hiring, regular, greeting, all in accordance with the process.

On the day of the wedding, it was extremely lively, Hong Chengchou really came to Jingbian Fort as agreed, and the role he played this time was still Liu Renyu's relative.

It can be said that this marriage is almost the same as Sun Yuyun's, it is very grand, and Du Ruonan is very satisfied with this. After getting married, Sun Yuyun and Du Ruonan, the wives of Liu Renyu, at least on the surface, got along well.

After Liu Renyu and Du Ruonan murmured in the cave room for a few days, he secretly ordered Chen Danqing to send 36 people as personal guards to protect Du Ruonan and go to Fujian to arrange the charter of the ship.

After all, there is a way out, and everyone is not panicking.

Besides, Hong Chengchou, the governor of Yansui, took the opportunity to give Liu Renyu as a high-ranking hall, and also told him a few things.

The first thing, Sun Chengzong, the governor of Jiliao, went to Liaodong after the beginning of the year, and after he came back, he wrote to the imperial court, saying that Jinzhou was lonely and hung outside the pass, which was not conducive to guarding, and that two cities such as Youtun and Dalinghe Fort should be built to make each other horns with Jinzhou, which was conducive to defense and gradually recovered the lost territory.

For Sun Chengzong's suggestion, the imperial court still approved in principle, but the imperial court meant to only build the Dalinghe Fort, and Sun Chengzong's meaning was to first build the right tun by the sea to get a stable stronghold, and then build the Dalinghe Fort as an outpost in Jinzhou.

The two factions were at loggerheads, but the court may have finally agreed to the plan of building Dalinghe Fort first, because Liang Tingdong, the secretary of the Ministry of War, supported this plan, so in the end, Liu Renyu was most likely to build the city or Dalinghe Fort.

Liu Renyu knew about this when he read the novel and watched "Those Things in the Ming Dynasty", so he didn't have any special feelings, he just said that he knew.

The latter thing made Liu Renyu very happy, and Yang He, the governor of the three sides, solved a lot of troubles for himself because he was grateful to Liu Renyu, so he also tried to recommend Liu Renyu's method of building a city with reinforced concrete to the imperial court, just like Hong Chengchou.

In fact, Yang He has never seen the effect of reinforced concrete, but he feels that Liu Renyu has always been very reliable, and he chose to believe Liu Renyu, so he directly wrote a book to explain the benefits of the reinforced concrete city construction method according to Hong Chengchou's description.

First, the method of building a city with reinforced concrete, without eggs, glutinous rice, and only lime and sandstone, can save a lot of money and grain for the imperial court;

Second, the city built by the reinforced concrete method is extremely strong, according to the Yansui governor Hong Chengchou saw with his own eyes, the divine power is like a Hongyi cannon, at a distance of 200 steps, dozens of bullets were fired in succession, and the city wall was not damaged in the slightest;

Third, the method of building a city with reinforced concrete, the time spent to build the city is very short, if the traditional method of building a city takes half a year, this method only needs one month to build a city, saving time and effort, and indirectly saving money;

Fourth, the master of this method of building the city is the Jingbian Fort Army Liu Renyu's department, the troops and horses of the department in recent years, killing the northern captives, beheading the construction of slaves, leveling thieves, the combat power is outstanding, if you enter the Liaodong to build a city, it is not a great help of the Liaodong Army.

Yang He's recital was sent to the imperial court, the emperor attached great importance to it, and the imperial court also attached great importance to it, but this is because this method of building a city no matter how you look at it, it is a wonderful way to save money, and now the court is poor jingling, and the emperor Chongzhen is wearing patched clothes and pants in order to raise military expenses, so when he heard that there is such a wonderful method of building a city, he can't help but be very surprised.

The emperor immediately asked the ministers, if this method of building a city with cement is really as powerful as Yang He said, can it be used?

The ministers didn't know what reinforced concrete was, let alone whether this method was useless, but since the governors of the three sides said that this method of building a city was reliable, it was probably still somewhat reliable.

However, after all, the construction of the city in Liaodong was a major military operation, and it was absolutely impossible to use this 'reinforced concrete' method of building the city because of a letter from the governor of the three sides, so Zhou Yanru, the first assistant, suggested that the Ministry of Industry should send a competent man to Jingbian Fort to find out.

Emperor Chongzhen agreed in principle, but he took into account that building a city has always been the business of the Ministry of Industry, and now he killed Liu Renyu, a local official who can build a city in a new way, halfway, but he was afraid that the people of the Ministry of Industry might not act out of public intentions and really reflect the situation, so he specially ordered his personal eunuch Wang Chengen to send a eunuch to Jingbian Fort with the people of the Ministry of Industry to find out.

If Liu Renyu's reinforced concrete city construction method is really as cost-saving, labor-saving, time-saving, and durable as Yang He said, then Liu Renyu's reinforced concrete city construction method will definitely be used to build a city in Liaodong this time.

Third, the governor of the three sides had specially reported to the court that Liu Renyu had killed more than 400 Mongols, and the emperor was very happy, and it is said that he also praised Liu Renyu a few words.

Fourth, due to Yang He's efforts to appease and Liu Renyu's brave generals to suppress thieves very effectively, the thieves in Shaanxi, including the Shenyi Kuibu who had just been beaten to the ground, as well as those famous and unknown thieves with thousands of people under their hands and tens of thousands of people under their hands, all surrendered, and the entire Yansui and Shaanxi were clean.

However, after these thieves surrendered, they all made a small request to Yang He, and when they were placed, they must not be placed in him Liu Renyu, because those thieves were afraid that he Liu Renyu would do the trick.

Yang He was happy to see that his wish to recruit an had been fulfilled, so he agreed to the thieves' request not to place them in Jingbian Fort. When the emperor heard the good news that all the thieves in Shaanxi had surrendered, he was very happy, and ordered Wu Xuan to bring 100,000 taels of silver to Shaanxi to comfort the thieves who surrendered.

Liu Renyu was speechless about this news, and he didn't want to say that these thieves who surrendered would inevitably rebel again after half a year, and it was useless to say it.

Fifth, if the imperial court decided to use the reinforced concrete method to build the city, Liu Renyu still needed to prepare for a good life and prepare to enter Liaodong to fight.

After Hong Chengchou finished saying these words, he praised Liu Renyu again, and then went back to Yulin.

Liu Renyu is ready to make every effort to prepare for the trip to Liaodong in the near future.
