Zhang Xianzhong is worthy of being a battle-hardened veteran, and in a short period of time, he calmed down and began to deploy troops to organize defense.

Judging from the number of Qing troops, it was only twice the size of the Great Western Army in Boryeong City. This amount is not enough to gain a crushing advantage.

As long as the Great Western Army fought steadily and did not make mistakes, the Qing Army would not get any good opportunities.

At that time, as soon as Zhang Dingguo and Zhang Nengqi's reinforcements arrived, Zhang Xianzhong could go out of the city to fight back, and eat this Qing army in one fell swoop under the front and back attacks.

In Zhang Xianzhong's opinion, Hong Chengchou is too confident, and even too confident.

He thinks that he can take Boryeong with only forty or fifty thousand people, which is simply wishful thinking!

Zhang Xianzhong was dressed in silver armor and personally stood at the head of the city to supervise the battle, and the soldiers suddenly felt a sense of pride in their chests.

Even their beloved Emperor Onishi can fight on the front line, how can they be greedy for life and afraid of death?

Zhang Kewang stood beside Zhang Xianzhong, his eyes full of determination.

Tartar, it's really the first time they've fought each other.

But he's not afraid. If you want to take over the world, you must not be afraid of any opponent.

If the Onishi regime wanted to finally decide that the world would sooner or later confront the Manchus, it was just a matter of bringing this duel a little earlier.

Tartars are also human beings, and they have no three heads and six arms, what is there to fear?

"Father, do you want to take a break, this tartar will be afraid that he won't be able to beat it for a while."

In order to make the atmosphere more relaxed, Zhang Kewang said half-jokingly.

Zhang Xianzhong was also amused, and sneered: "When did you kid learn to be so flamboyant." But the Tartars don't really seem to have any intention of attacking immediately. Let's see, they want to play yin. ”

Zhang Xianzhong pursed his lips and said, "Look, do they want to use acupoints to attack?" ”

Zhang Xianzhong pointed to a mound piled up high and said in a deep voice.

This method of acupuncture is not special, and even everyone has used it.

However, the shortcomings of this method are too obvious to be a good siege method, and at most it can only be used as an auxiliary to cooperate with a frontal attack.

The biggest disadvantage of cave attack is that it takes too long, and it takes a lot of time to dig tunnels, which can easily be consumed by the defenders in this case.

Reinforcements will come after consumption, and advantages will be gone after consumption.

So when Zhang Xianzhong saw that the Qing army began to dig tunnels and prepare for cave attacks, he was in a very good mood.

Well, there are times when Tartars are stupid.

You just dig the tunnel, and our Lao Tzu's army will come back soon!

...

...

The Qing army was digging the tunnel unhurriedly, and Hong Chengchou sat calmly in the formation to command.

The Qing army didn't seem to be in a hurry at all, as if it didn't matter if the tunnel was dug for ten days and a half months.

There is only one thing they care about, that is, they will never let go of the cavalry who came out of Huaiqing City to report for help.

The cavalry apparently wanted to go to the mountains of Daba to seek reinforcements from the main Onishi army stationed there.

In Hong Chengchou's plan, this must not be allowed.

He calculated this point in time for a surprise attack, and if the Great Western Army in Daba Mountain came back to help, the advantage of the Qing army would be gone.

Time, time is the most precious thing.

In fact, the reason why Hong Chengchou is so confident is because he has discovered a new tactic that is very useful.

Strictly speaking, this tactic was first invented by the Ming army.

That is to blow up the walls with gunpowder.

When Gao Jie led his troops north, he used this tactic many times, and he tried it repeatedly.

The Green Camp Army often blew up the city walls before the Ming army led by Gao Jie rushed up and quickly resolved the battle.

Later, Hong Chengchou became interested in this matter.

After questioning the green battalion soldiers and on-site observations, Hong Chengchou felt that it might be a problem with gunpowder.

He ordered people to dig down the section of the blown city wall and found fragments of the coffin.

At that time, Hong Chengchou sighed, could it be that he put gunpowder in the coffin and then ignited it, and used the explosion to blow up the city wall?

Hong Chengchou decided to give it a try.

Anyway, those walls have already been blown up, and I don't care about blowing up more.

He ordered the tunnels to be dug first, and then the coffin filled with gunpowder was placed vertically inside.

The result was unexpected, and the section of the wall facing it was really blown open. Although it was not completely blown up, the effect was already very good.

As if he had obtained a treasure, Hong Chengchou immediately wrote this tactic into the song, and ordered someone to send it to the capital newspaper to know about it with the regent Dorgon.

Dorgon's foresight would have ordered the Qing army to make great use of this tactic.

The Qing army itself has a very strong combat effectiveness, and the only thing it lacks is the ability to attack fortifications.

After all, red-coated cannons can't be equipped everywhere, and using red-coated cannons against ordinary small towns has the feeling of killing chickens with knives.

And if there is this tactic of shelling up the city, the Qing army will be more comfortable when attacking the city.

Liu Jinzhong and Shuo Zhan had never seen this kind of tactic, and even Tong Yanghe, who had always been known for his knowledge, was surprised.

"Hong Duxian, what are we going to do with all our efforts digging tunnels! Now it's time to take Huaiqing City in one go! ”

Tong Yanghe was already anxious, and he was very dissatisfied when he saw Hong Chengchou digging the tunnel unhurriedly.

"It doesn't take much time to dig tunnels."

Hong Chengchou stroked his beard and said lightly.

"It doesn't take much time to dig tunnels?"

Tong Yanghe's eyes widened: "Isn't Hong Duxian joking?" Without a ten-day and a half-month-long tunnel, this tunnel can be dug successfully? ”

Hong Chengchou said with a smile: "The governor said that the tunnel only needs to be dug very narrow, and it only needs to be dug under the city wall, and it doesn't take much time. ”

"Huh?"

Tong Yanghe looked at Hong Chengchou like a monster: "What's the use of digging the tunnel like this?" The tunnels are used to transport soldiers into the city! ”

"No, no, no."

Hong Chengchou shook his head and said, "This governor dug the tunnel not to transport soldiers into the city, but to blow up the city wall. ”

Hiss!

Tong Yanghe gasped when he heard this.

"How is it possible to blow up the city walls?"

"How could it be?"

Hong Chengchou raised his eyebrows and said, "Do you see that coffin?" The Governor used it to blow down the walls. ”

Tong Yanghe was desperate in his heart.

Governor Hong can't be an old fool, right?

If the coffin could blow down the walls, the sun would come out of the west.

Tong Yanghe swallowed and spitted at the mouth: "Governor Hong can't be gullible and strange powers!" ”

Hong Chengchou glanced at him: "Who said that Ben Duxin is confused." The Governor had to rely not only on the coffin, but also on the gunpowder that the coffin was filled with! ”

"Yakuko?"

Tong Yanghe vaguely felt that he understood.

Both artillery and muskets require the use of medicine. As for the artillery battle, it is even more powerful to exert its power through medicine.

However, the gunpowder itself is limited in power, and is more used as a help for lead shooting.

Relying on gunpowder and coffins to blow up the city wall, Tong Yanghe didn't believe it.
