If Liu Erzu's subordinates, who fought in Yizhou, Tai'an, and Zizhou, and the rebel armies such as Ma Liang, Gao Lin, and Song Dezhen who were operating in the East China Sea (now southeast of Lianyungang), could cooperate with the battle and contain the Yi and Pijin armies, the Red Turban Army would gather more than 6,000 men and horses, and with the help of firearms, there might be hope for victory.

But Meng Jiucheng felt that it was not an easy thing for Liu Erzu and other rebels to fight together. At that time, the rebel armies were not subordinate to each other, and they fought separately, and there was no idea or intention of coordinating and fighting together. This is also an important reason why the Jin army counterattacked in the early stage and was able to break through each one.

It's a little difficult to get south, and it's not easy to go north. Mizhou to the north was occupied by Guo Sansuo's troops of the Red Jacket Army, and Juzhou was controlled by Yang An'er's subordinates, and Meng Jiucheng did not want to clash with them too early.

After thinking about it, Meng Jiucheng thought that it was indeed difficult to expand in the south and north, so it was better to slow down for the time being. On the one hand, he managed the occupied land, resettled the displaced people, reclaimed wasteland, replanted crops, recruited southern merchants, and purchased grain; On the one hand, it sent people to conduct exploratory liaison with various rebel armies, coordinated operations, and expanded the space for strategic activities.

Although the Jin army in Haizhou, Yizhou, and Pizhou is a threat, it is not very likely that they will take the initiative to attack now.

In order to avoid the advance of the Mongolian army, the Jin State moved southward, and the strategic focus shifted to the Guanhe (Tongguan-Yellow River) defense line, and the forces that could maneuver and fight in Shandong and Lianghe were very limited. Therefore, the Jin army's suppression of the Red Jacket Army can only be a key offensive and break through each one. At the local level, they could only defend such an important city as Zhouzhi, and they had more than enough to defend but not enough to attack.

Therefore, Meng Jiucheng should pay special attention to the Jin Army's mobile corps that attacked Yang An'er in Dengzhou and Laizhou in the north. As long as it doesn't make a big noise, those who occupy the state and seize the government will have Li Quan, Liu Erzu and other big heads in front.

In addition, Meng Jiucheng also felt the need to concentrate on scientific research. After all, real money is limited, and if you want to buy grain in large quantities and at a high price, you can't support it for too long.

From the perspective of time, in more than two months, Yang An'er will be defeated, and Li Guosan will be killed by the Jin army later, but the situation in the north will be a big change.

Of course, the Red Turban Army did not completely stop its operations, and the Wulian area (now Wulian County) in the northwest of Rizhao County had to be swept away and controlled. Occupying the Wulian area strategically formed a southern and eastern flanking attack on Juzhou (the county seat of Juxian County), and also formed a barrier and buffer south of Mizhou and north of Rizhao.

For this kind of strategic deployment, Meng Jiucheng generally thought about it almost before discussing with his subordinates to improve the details. After all, it was his judgment based on the trend of history, and it is relatively difficult to find a reason for it when he delves into it.

Fortunately, so far, Wang Zhongfeng and others have not investigated the root cause, whether it is trust or blind obedience because of closeness and affection, Meng Jiucheng does not need to figure out the reason.

Thinking about it, Meng Jiucheng put these into writing, and then summoned the soft sister system to seek help in making glass.

Historically, the raw materials for making glass were very simple, and the earliest glass was potassium-calcium silicate glass, which became soda-calcium silicate glass after the introduction of soda ash into the glass, which has better transparency, corrosion resistance and operability than the former.

But to make colorless glass, manganese oxide must be added as a color toner; If lead oxide is introduced, crystalline glass with a high refractive index and high brightness can be produced.

Clay crucibles, quartz sand, soda ash, feldspar, limestone, etc., with the help of the Soft Sister system, are no longer difficult, although the number will be limited in the initial stage. In the future, the establishment of a separate raw material manufacturing department can also solve this problem.

Since there was a limit on the quantity, Meng Jiucheng decided to add more processes to turn the manufactured glass into something more high-end, such as a mirror.

"Since it is a mirror, the product does not need to be too big, let's use the pressing method first, the process is simple, the mold can be a whole, and the surface of the product will not leave a mold gap." The soft girl system suggested: "As for the blowing method, let the craftsmen experiment and practice, and then use it after they are proficient." ”

"You have the final say on this kind of professional thing." Meng Jiucheng is very modest, and it can also be said that he is self-aware.

When it comes to the education of later generations, it is really miscellaneous but not refined, knowing a little bit of everything, but not being refined in anything. If you want to study it yourself, it's not impossible, but with a lot of time and thousands of experiments, Meng Jiucheng really doesn't have that patience.

"To build a mirror, use the tin amalgam method first, although it is toxic, it is not too much of a problem to pay more attention." When the soft girl was recognized, she continued: "If it is successful, it will not only be sold to the Southern Song Dynasty, but also sold to overseas countries, and it will also make a lot of money." ”

"It's going to be successful, I'm optimistic about you!" Meng Jiucheng complimented and said, "As long as there are one or two finished products, a small mirror the size of a palm can cause a sensation outside, right?" With such a temptation, it is not difficult to attract merchants to bring grain. ”

"For the sake of a triple profit margin, you can risk guillotine, which celebrity said that, you know?" Soft girl sneered: "This is you human beings, greedy, selfish, ......"

"Don't hit a blockbuster, okay?" Although Meng Jiucheng admits that Soft Mei is right, she still has to defend human beings and fight for her own face, "In the world, good people still account for the majority." I, for example, fought for justice and justice. ”

"Hey, it's like it's true, who believes it?" The soft girl teased.

"Believe it or not, I do." Meng Jiucheng rolled his eyes and said, "Otherwise, how could I send you to help me?" Speaking of this, he couldn't help but ask the previous question, "By the way, what's the matter with you, who sent you?" ”

"I don't know." The soft girl replied so crisply.

If you don't know, you don't know, Meng Jiucheng closed his mouth knowingly. In other words, it's really convenient and powerful to have this system, no matter where it comes from?

…………

People's brain power and energy are limited, and Meng Jiucheng must focus more on war, although the situation has greatly improved, but still cannot be taken lightly.

Now it has two county seats, covering an area that exceeds the two counties, and the army has been continuously recruited, absorbed, and integrated, and has reached 13,000. The establishment of the militia has liberated more and more garrisons, which are constantly going to various defensive lines.

The main force led by Meng Jiucheng expanded from 4,000 to 7,000 people, all of whom remained in the newly occupied territory and were divided into two battalions, north and south; Xiao Ying and Zheng Si'an each led a battalion to deploy in Junan County.

After strategically slowing down the offensive for a while, all that remained was to train the men, replenish the armament, and carry out "arch" tactical operations to the surrounding vacuum area. Arch, try to avoid conflicts, do not move much, do not show mountains and water, and control village by town.
