Li Laoer asked Sun Chengzong again to provide him with two thousand kilograms of gunpowder, but Sun Chengzong agreed without hesitation.

Two thousand kilograms of gunpowder were sent to Li Laoer's military camp. Li Laoer began to make two types of gunpowder bags, one called poisonous fire bag, which was to add realgar to the gunpowder, wrap it with a layer of oil paper, and leave only a small hole that can pass through the fuse, and then wrap it with cotton soaked in tung oil, wrap it with cowhide on the outside, tied tightly with a rope, which became a poisonous fire bag. After this gunpowder bag was thrown out, the explosion was not very powerful, but the cotton soaked in tung oil burned, ignited the outer fur, and released thick black smoke. After the realgar was heated, it reacted and turned into arsenic, which could produce toxic choking smoke.

In fact, the poisonous fire pack is a weapon created by Li Lao Er based on "The Art of Heavenly Works" by simplified people. The 10,000 enemy is a weapon to defend the city. It is a mud shell black [fire] bomb filled with mud shells and tung oil. The outside is wrapped with a quilt soaked in tung oil. There are additives that can produce poisonous mist in the gunpowder. However, the 10,000 enemy is too heavy and can only be thrown from the top of the city. Li Lao Er's poisonous fire pack can be tied with a rope and thrown out like a meteor hammer, which is suitable for use in field battles.

Another type of gunpowder bag is actually a personnel killing bomb. The method is to wrap the gunpowder with thick kraft paper, leaving only a small hole to insert the fuse, tie it tightly with a rope, put a layer of iron sand and iron nails on the outside, and then wrap it with thick kraft paper. The outermost layer is wrapped with cowhide and tie it tightly with a rope.

After multiple layers of sealed gunpowder, an explosion will occur after the fuse is burned out. The innermost gunpowder explodes and throws out iron sand and nails, which can kill the enemy.

Like the poisonous fire pack, this kind of killing gunpowder can also be tied with ropes, circled like a meteor hammer, thrown out, and thrown into the enemy group. After the explosion, it can kill and injure the enemy in large quantities.

Each poisonous fire pack consumes one pound of gunpowder, and each killing gunpowder pack consumes five pounds of gunpowder. Both types of gunpowder weigh ten pounds, and they can be shot out like a meteor hammer, and can be thrown thirty steps away. People with great strength can even throw fifty steps away.

In later generations, athletes could throw 6 or 70 meters away from the 15-pound hammer ball, and the world champion could throw 80 meters away. However, the ten-pound poison fire bag and gunpowder bag made by Li Laoer was not uncommon to throw 50 steps.

Li Laoer and his brothers made 500 poisonous fire packs and 300 gunpowder packs.

Sun Chengzong also gathered the people near Tongzhou. The Ming army made all preparations and had not received any news that the Jin army had broken Zunhua City.

After all, Zunhua's city is solid. In real history, if it weren't for the Later Jin Dynasty's fine works, it would be really difficult for Huang Taiji to conquer Zunhua.

The Later Jin army could not capture it for a long time, and the city was filled with corpses of Baoyi Aha and the Mongols. However, the Later Jin archers who were sieging the city also brought great losses to the defenders on the city. Most of the Mongols who died under the city were Tumots.

The Tumotes, who were used as cannon fodder by the Later Jin army, were dissatisfied, which also created an opportunity for Li Laoer's plan to disagree.

On November 19, Meile Ezhen Samuhatu, Zhengbai Banner, finally led his troops to attack the city, and the Later Jin army captured Zunhua City. The Later Jin army entered the city, because the Later Jin army suffered a great loss in Zunhua. After Dorgon attacked the city, he slaughtered all the Ming army and all the adult men in the city. The Later Jin army thought that it was useless were also slaughtered. The women and children left behind were robbed and taken away by the Later Jin Dynasty and sent to the outside of the pass to serve as Baoyi Aha.

But Liu Ce and Zhang Shixian survived by chance because they hid in the tunnel and escaped the search for the Later Jin Dynasty.

By November 20, Tongzhou City finally received news that the Later Jin army had captured Zunhua.

"What is coming is finally here!" After receiving the news, Sun Chengzong immediately ordered the troops to prepare for combat.

After learning that Zunhua was massacred by the Later Jin Dynasty, Li Laoer was indignant: I have bought time for Yuan Chonghuan, but he only dared to hide in Jizhou City and did not dare to break the siege of Zunhua at all.

If Yuan Chonghuan is a Chinese jian, this statement may be inappropriate, but he is indeed a mediocre person and a pig teammate. Sometimes pig teammates are more terrible than enemies. There is no saying that you are not afraid of enemies like gods, but are you afraid of teammates like pigs? If Yuan Chonghuan did not kill Mao Wenlong, the Later Jin Dynasty would not dare to invade and rob, and perhaps the Ming Dynasty could have supported it for decades.

Since Zunhua has been lost, if the Later Jin army arrived near Tongzhou next, they found that Sun Chengzong was stationed in Tongzhou. With Huang Taiji's character, he would definitely not attack Tongzhou, but instead detoured directly to the capital.

In order to make the Later Jin army come to Tongzhou to encounter difficulties, Sun Chengzong sent cavalry to take the initiative according to Li Laoerxian's plan.

Sun Chengzong sent You Dai to lead three thousand cavalry, cooperated with Li Laoer to attack, and was responsible for harassing the Later Jin army and attracting the Later Jin army to the city of Tongzhou.

"Know yourself and your enemy, and you will never be defeated in a hundred battles. If you want to win, you must be familiar with the enemy situation. Jiannu used scouts and cavalry to block the battlefield information of our army. Only when we can win without closing the mail at night can we obtain the information of Jiannu. There are 100 elite soldiers in the lower officials who do not accept them at night, and they can obtain the enemy situation for the general." Li Laoer said to You Dai.

You Dai said: "Brother has 50 nights without stopping the quizzes. Although he is not as good as his brother's elite night without stopping, he has followed You for many years and met Jiannu and can still fight."

As a military general, You Dai was not as magnificent as a civil servant. Seeing that Li Laoer was brave in fighting and killed many Jiannu, he offered a clever plan to the supervisor, so he naturally treated him as a brother.

"Okay! I won't accept it for one hundred nights. Brother, you will send fifty people to spy on the military situation of Jiannu." Hearing You Dai's tone, Li Laoer also changed his words, calling him the eldest brother and calling himself the younger brother.

One hundred and fifty Ming army members left Tongzhou City at Yebu, led by Li Laoer himself to the Zunhua direction to spy on the enemy's situation.

Li Laoer brought 150 Ye Busuo and he had just left Tongzhou City for about fifty miles. Someone came to report that there was a group of about 100 Later Jin cavalrymen in front. Li Laoer immediately ordered that everyone hide in the woods. The Ming army hid in the woods and observed the Later Jin cavalry outside. He saw that the Jin soldiers were all wearing leather armor, wearing cotton hats or leather hats.

"It's the Mongolian Tartars!" Li Laoer said.

If face to face and fight head-on, more than 100 Korchin Mongolian cavalry would definitely not be the opponent of the 150 Ming army to stop at night. However, the Mongols were light cavalry and never fought head-on with any heavy cavalry. They would shoot arrows around their opponents, shoot a rain of arrows, and immediately use their advantages of good mobility and fast speed to leave. If the opponent does not catch up, the Mongols would turn back to shoot arrows; if the opponent catches up, the Mongols would use the Mangu malign tactics to drag down their opponents. If they encounter a large group of Ming troops, the Korchin Mongolians could still summon the Later Jin army to launch an attack.
