Huang Han personally came to Chifengwei to sit in the town, because the military and civilians need to be stationed for a long time, thousands of large and small yurts have been built on this prairie.

The technology of the "Red Banner Army" sappers in building yurts is probably no worse than that of the Mongols, especially the extra-large yurts that can accommodate 500 people for meetings and studies, and the vast majority of the Mongols do not have this ability at all.

Huang Han was not worried about the war situation, but concerned about safety and the progress of prospecting, and whether he could complete the two-point and one-line fortress defense system before the ground froze three feet this year.

If this defense line is completed this year, when the spring flowers bloom next year, tens of thousands of soldiers and civilians will have to be organized to build the concrete road from Chifengwei to Ningyuan Port.

It is not only to meet the needs of troop mobilization, but also to improve the efficiency of transporting raw materials such as pig iron, iron ore, coal, etc., and save costs.

Zheng Guochang and Liu Zhilun had just left Beijing for less than two days, and an urgent report of 600 li was sent to Huang Han.

Knowing that the imperial court finally broke the ancestral system and canonized the king of the opposite sex, Huang Han was not excited at all, but felt that the Ming Dynasty was already weak.

There is nothing to be ashamed of being crowned king by the Ming Dynasty, and there are too many princes in the Nanming Dynasty who have a dog's tail and a mink in history.

Zheng Chenggong, Li Dingguo, Li Chengdong, Sun Kewang, Liu Wenxiu, etc. are all princes, and there are several vassal kings.

Huang Han did not immediately go back to Shanhaiguan to wait for the angels, and was ready to invite Zheng Guochang and Liu Zhilun to Chifengwei to have a look, so that they could understand that the "Red Flag Army" was not passive and had been actively deploying.

Zheng and Liu, the two ministers, did not see Huang Han when they came to Shanhaiguan, and learned from the mouth of Huang Yizhou that Huang Han led his troops to clean and conquer the Mongolian tribes such as Karaqin, Khalkha, and Chahar, and had penetrated into the grassland for more than 1,000 miles.

Their eyes lit up on the spot, and they immediately stated that they could not miss the fighter plane in order to let the captured general return to Shanhaiguan in order to receive the order, and they would rush to the prairie to find Huang Han.

Huang Yizhou personally ordered a personal guard cavalry to accompany his in-law Zheng Guochang on the road, and the impatient Liu Zhilun was already escorted away by three hundred ironclad soldiers led by Liu Quan.

The quality of the official road from Shanhaiguan to Ningyuan is comparable to that of the main road from Jingshi to Tianjin Wei, and there are post stations along the way to provide food and horse feed.

Liu Zhilun's more than 300 people stayed in Ningyuan City in the afternoon of the same day, and met Huang Han in Chifengwei in the early morning of the next day and in the evening.

After a long absence, the two were very happy, and they drank and chatted in a delicate yurt built until the third watch.

Liu Zhilun deliberately avoided the status quo of the "Red Flag Army" system having become independent and the Ming Dynasty, and only talked about the valuable experience of the "Red Flag Army" in the past few years.

He didn't know that Huang Han should be difficult to ride a tiger, if he gave in to the emperor would not have a good result, choosing to be tough in the end was actually the only way, he was loyal to the emperor and did not want to harm his friends, so he did not involve sensitive topics.

Liu Zhilun, who was full of interest, also took out a drawing and suggested that the "Red Banner Army" should produce mass production equipment as soon as possible.

This is an improved version of the vehicle-carrying gun he designed last spring, because it is made up for by the number of guns that are used to take into account the speed of reloading, which is about the same as the original equipment of one carrying gun, and now the car is equipped with three rods.

Daming's finances are tight, and it is about to run out.

Liu Zhilun, a cabinet elder, personally supervised the Military War Bureau, and only produced 100 new three-barreled vehicle-mounted guns to equip the Beijing camp.

Without him, because the high-quality steel produced by the "Red Flag Army" system must be used to meet Liu Zhilun's requirements, the cost is too high, and the cost of a three-barreled vehicle carrying gun is as high as 120 taels of silver.

Huang Han looked at Liu Zhilun's design and thought that such a vehicle-mounted gun had reached the cost of one pound of Furlong machine guns, and it was only three large projectiles, which was too cost-effective.

The barrel of the lifting gun was very long to six feet, and such a front-loading smoothbore gun could not solve the big problem of not being able to reload quickly, and the rear-loading Furlong cannon with a direct replacement gun was five or six times slower.

There is really no need for the "Red Banner Army" to be equipped with such weapons.

But for the sake of Liu Zhilun's face, Huang Han is ready to arrange the production of 200 aircraft, and at the end of this year, he will use these 200 three-barreled vehicles to carry guns to Emperor Chongzhen as a gift.

Huang Han learned that in order to develop new weapons, Liu Zhilun and Zheng Guochang often went in and out of the military war bureau and the Anmin factory and the new factory.

The last Ming Dynasty had a big explosion in Wang Gongchang, as we all know, in fact, there were many explosions, not only in the sixth year of the Apocalypse, almost every year, but the size was different.

Chongzhen's 11-year-old new factory and Anmin factory have exploded one after another, and the destructive power is amazing, resulting in the Ming arsenal being blown up, killing 10,000 military and civilian eunuchs and more than 10,000 injured.

Although Huang Han reminded Zheng Guochang and Liu Zhilun early on to strengthen the management of gunpowder, the flag guards also made secret visits to arrest spies and saboteurs at all times.

But whether the major accidents recorded in history could be avoided Huang Han really didn't know a little bit in his heart.

Huang Han said with a serious face: "Do you still remember the gunpowder disaster of Wang Gongchang in the sixth year of the Apocalypse?" ”

Liu Zhilun is a native of Yibin, Sichuan, a jinshi in the first year of Chongzhen, and of course he was not in Beijing in the sixth year of the Apocalypse, so he could not be an experiencer.

He said: "Although this official did not personally experience the explosion, Chongzhen saw the Wang Gong factory after the explosion many times in the first year, and it was so tragic that it has not been fully restored there.

The prince suddenly mentioned this matter, could it be that he was worried that a similar accident would happen again. As far as this official knows, many parties have analyzed it afterwards and it may not be an accident, but may be a natural disaster. ”

Huang Han said: "Whether it is a man-made accident or a natural disaster, it is always because Wang Gong's factory has stored too much gunpowder.

Today's gunpowder inventory of the new factory and the Anmin plant may have reached a peak again, which directly leads to improper storage and insufficient management personnel.

In order to avoid another catastrophic accident, Benjue suggested that the Lord quickly send someone back to Beijing to evacuate the stockpile of gunpowder.

If there is really no place to scatter the storage, the 'Red Flag Army' can keep it on its behalf, and if the Gunpowder Bureau has too much stock, it can be purchased at a fair price, and it can also be replaced by the standard armor and self-generated guns of the 'Red Flag Army'.

The purpose is not to make a huge powder keg in the Jingshi, in case of explosion, tens of thousands of houses will collapse, and tens of thousands of military and civilian officials will be killed and wounded. ”

Of course, Liu Zhilun was concerned about the safety of the soldiers and civilians in Beijing, and when he heard Huang Han say it so seriously, his forehead was sweating.

He was a powerful faction who served as a squire in the military department and a secretary of the military department, and now he is a cabinet minister, and his words are effective, because he often goes to the new factory and the Anmin factory under the jurisdiction of the Military Bureau, he knows that there is indeed a lot of gunpowder stockpiles.

If you can exchange gunpowder for some of the weapons and sophisticated equipment of the "Red Banner Army", it will be very good, and if you can sell gunpowder to earn a part of the profits, you can also support many craftsmen of the gunpowder bureau.
