Liu Zhilun has been with Huang Han for eight years, and he knows the roots, and he knows that with Huang Han's current strength, he can't calculate the gunpowder in the Ming arsenal.

Intelligence shows that the total amount of gunpowder produced by many gunpowder factories in the "Red Flag Army" system has reached more than three times the total output of the Ming Dynasty.

The gunpowder factory of the "Red Banner Army" could not be built in the city at all, but chose to stay away from the densely populated area of the mountain recess, near the "Tiger's Den City" on the Dome Mountain, Tiger Mountain, Tianma Mountain, Heifeng Mountain and other small hills have been built gunpowder factories.

In order to reduce the possibility of huge losses caused by accidents, Huang Han deliberately did not build a large-scale gunpowder factory.

Disperse production in a small but many way, a gunpowder factory with two or three hundred craftsmen is the limit, and there are many factories in the mountains near the city of "Han River Province".

The inventory will not be concentrated, and the powder magazines built in the mountains, and even in the caves, can definitely prevent idlers from entering and prevent fire.

The gunpowder produced by the "Red Banner Army" system is not entirely military, and the proportion of civilian use is even larger, and too much gunpowder is needed to blow up mountains when building roads, and blowing up ore veins when opening mines.

In order to attract enough attention, Liu Zhilun sent Liu Quan to lead a hundred general ironclad cavalry to rush back to Beijing on the spot.

He wrote letters to Chen Xinjia, the secretary of the Ministry of War, and Liu Zunxian, the secretary of the Ministry of Industry.

Liu Zhilun is also bad at learning now, and he told the two Shangshu lords in the letter that he learned a shocking piece of information after meeting the general of the conquest.

Jiannu, who was lurking in Beijing, made careful preparations to carry out sabotage, and the goal was to blow up the new factory and the Anmin factory under the jurisdiction of the Gunpowder Bureau, and it was not clear when to do so.

In order to prevent problems before they occur, it is imperative to evacuate the stockpile of gunpowder as soon as possible.

If the distribution to the armies is far from being able to digest the inventory, it can be sold to the "Red Banner Army", or it can be replaced by the self-generated guns and armor of the "Red Banner Army", and the "Red Banner Army" can also be entrusted to store on behalf of the "Red Banner Army".

Liu Zhilun believed that with his two letters, it would be impossible for the Ministry of War and the Ministry of Industry to sit idly by, because if there was a real accident, the two Shangshu who were indifferent to the information would be guilty of great crimes!

The next day, when Huang Han was about to accompany Liu Zhilun to visit several small fortresses under construction, Hanzi personally came to report the latest news.

Hanzi and Liu Zhilun are also old acquaintances, and when he came to report the military situation, he did not deliberately avoid it at all, and he also took the initiative to invite Liu Zhilun to drink.

The tide is rising, and now Hanzi is also famous, not only is the chief military officer of Zuodu Shanhaiguan in the first grade, but also because he swept through Ordos and beheaded tens of thousands of Tartars.

Now he has the title of forward general and is one of the eight major military officers of the Ming Dynasty.

Of course, Liu Zhilun wanted to give face to the first general of the "Red Banner Army", and Le Zizi agreed to Hanzi's invitation, and named him to eat roast whole sheep.

Hanzi was excited when he reported that the 50,000 Jiannu cavalry and the Horqin cavalry had already crossed Jinzhou and came in the direction of Chifengwei, and it was expected that there would be an encounter in three days.

In early February, the Mongol tribes within a few hundred miles centered on Chifengwei were targeted to be eliminated or conquered, and many chiefs ran to Shengjing to cry to their masters.

He was not afraid of fighting with the "Red Banner Army" on the grassland, but the agricultural season did not wait for anyone, and he did not dare to miss the spring ploughing when the grain was already unsustainable.

In the changing world, Jiannu was reluctant to go to the steppe to fight, because they knew that there was no oil and water in such a battle, and they would not get any capture when they dealt with the Mongols in the past.

Now it's time to deal with the "Red Banner Army", and the trouble is even greater. If you get the capture, you don't think about it, maybe you will lose your life.

The reason is very simple, after many years of fighting with the "Red Banner Army", he has not won a single victory, and Jiannu has a shadow in his heart.

The 500 captives who were released had already told their tribesmen what had happened to thousands of elites with white flags, and now the whole of Liaodong knew the fate of Duoduo, and knew that all the Manchu and Mongolian cavalry who refused to surrender were killed.

Now that the master is about to send troops to fight in Yuanbao Mountain, which is thousands of miles away from Shengjing, will the scheming "Red Banner Army" set up an ambush there?

The military nobles who had no morale refused to come forward, and the red gangster was the general who ordered Dolgon, who knew that Dolgon fell from his horse and broke his leg that afternoon because of his heavy heart.

The red gang had to consider a replacement, he thought of Abatai, who knew that the order had not yet been issued, Abatai's eldest son came to take leave, and his old son was sick and bedridden.

That's right, what can you do if you know that Dolgon and Abbatey don't want to fight?

He had to send Haoge to lead the troops, appoint Du Du as the deputy general, transfer 20,000 soldiers from the Eight Banners, and recruit 30,000 Mongolian foreign vassals dominated by Horqin to go on the expedition.

It is difficult for Jiannu to collect intelligence now, and they do not know how many people in the "Red Banner Army" are plundering in the prairie.

For the sake of safety, the Red Gang told his eldest son, Hauge, to rely on.

If it is found that the "Red Banner Army" has fewer men and horses, it can fight, and if the number of men and horses there has exceeded 10,000, it must give up the plan to recapture the pasture and withdraw immediately.

He also stressed that he could not march into the mountains, but that he must camp in the wilderness, and that his sentry horses must go fifty miles forward, and that he should not enter the dense forest.

Obviously, Jiannu was afraid of being ambushed, so it was really unlikely that he would be ambushed again cautiously.

Of course, the 50,000 Manchu and Mongolian cavalry came to attack Huang Han, and of course they couldn't wait to ignore it, the entire Chifeng defense line was under construction, and there was not even a completed fortress.

In the event of a surprise attack, the hundreds of thousands of miscellaneous servants who were requisitioned to build the city fortress will suffer heavy losses.

Nowadays, the "Red Banner Army" has raised the standard of compensation for the death in battle and death in the line of duty to 100 silver dollars, respecting the lives of the Han people, even if the miscellaneous servants who came to build the building were killed by the enemy, their families can also receive the same pension.

This means that in case 100,000 people were slaughtered by Jiannu, the "Red Banner Army" would have to pay 10 million silver coins, that is, 10 million taels of snowflake silver, just for direct compensation.

For the safety of the people, the battlefield could not be placed in Chifengwei, and the ten battalions of men and horses and the guards battalion marched east to prepare to meet the battle at the northern foot of Wulan Mountain, six hundred miles west of Chifengwei.

At the same time, Huang Han issued an order to Song Pengfei, who had already come to Ningyuan to take the town, to launch a wave of attacks and advance the defense line to Jinzhou for at least ten miles.

Liu Zhilun is his own person, and Huang Han did not hide it when he gave the order.

Seeing that the "Red Banner Army" was about to face the attack of the Manchurian and Mongolian cavalry, how could it be said that at this time the "Red Banner Army" should be dispatched to Shaanxi to deal with the Liukou and 60,000 or 70,000 Manchu and Mongolian cavalry, which had grown to more than 500,000?

Shaanxi has already lost more than ninety percent of its territory, thanks to Xiong Wencan's large number of men, food, and military supplies.

Today's rogues are in full swing, and there are tens of thousands of Manchurian cavalry.
