Of course, the guns used by the artillery posts of the battalions were not Hongyi cannons.

That thing is an artillery unit, and it can only be used for a few thousand catties of siege.

But in small-scale operations, if you need fire support, and if you want to be easy to carry, then use small cannons.

The general ones such as tiger squat guns are outdated again.

Yang Chengying hoped that John Tang would build a wheel, the range was not too far, and the power was enough to lay down some rudimentary walled cities.

Stimulated by the permission to build a church, John Tong really built it.

That is a light long-barreled gun, about 2.2 meters long, with a caliber of 110 mm, a weight of 185 kilograms, a charge of eight taels, a firing range of 500 to 600 steps, and a plus one or two can reach 750 to 900 steps.

It's just that nine taels of medicine is already the limit, and you can't reload too much, otherwise there is a danger of exploding.

Thanks to the long-established technology of artillery production, as well as the popularization of culture.

Already a few battalions have begun to equip, envying others that are not equipped.

This caused Yang Chengying's ears to always be quiet, and someone was looking for him to ask for a gun.

"Dashuai, you call me."

Shang Kexi was ordered to come to the General Military Mansion.

"Well, you sit."

Yang Chengying was reading a book, raised his head, and motioned for him to sit down.

After Shang Kexi sat down, Yang Chengying said: "Here's the thing, all kinds of signs indicate that Jianyu has crossed the Great Wall from Jizhen to Mongolia through Liaoxi and invaded Beijing. ”

"Oh, we have to support Kyoshi!" Although Shang Kexi has never personally contacted Jingying, he has heard a lot of stories about Jingying from Peng Qigu.

This gave him the impression that Jingying was all rookies.

"That's right, but I can't do it right now."

Yang Chengying said: "Walking on the sea, I can't gather tens of thousands of troops in my life. Go to Liaoxi, and the Guan Ning army with Yuan's division doesn't need me. ”

"That's right, don't be able to rescue, and make a fuss for yourself." Shang Ke said happily.

"So, I plan to go north to attack Haizhou and take it permanently."

Yang Chengying sighed and said, "But after taking it, I may not be able to continue to go north, and I will fight west." ”

To walk the passage, the road from Jinzhou to Gaizhou must be opened in advance.

Shang Kexi thought so: "It really needs to be like this, if you don't rescue in time, the responsibility of the marshal will be great." ”

"Therefore, Haizhou City needs a handsome person to guard for me."

Hearing this, Shang Kexi already understood.

He didn't hesitate for a moment, but asked, "Who will succeed me?" ”

"I plan to let Zhang Cunren replace you, and Jin Guochen and Kong Youde will cooperate with you to defend the city." Yang Chengying said.

Shang Kexi nodded: "It's rest assured to have them." However, the subordinates also have a sentence that they want to tell the marshal in advance. ”

"You say."

"The enemy is strong and we are weak, which is an objective reality. The city of Haizhou was besieged, and the commander was asked not to rush into a decisive battle with the enemy, but to attack and harass. ”

"That's exactly what I want to tell you."

Yang Chengying stood up and explained his attack strategy in detail to Shang Kexi, so that he had the bottom of his heart.

Although Haizhou City is a lonely city, there is Ximu City in the south, and the area is mountainous.

Behind Ximu City is a large area of ridge piers, which is the support base of the Jinzhou army and the root of Jin Guochen's attack.

To the south of Haizhou is a vast grassland.

Yang Chengying's strategy was to harass the south with cavalry, and the southeast with infantry skilled in mountain warfare.

In this way, the Houjin army was constantly harassed, forcing it to retreat.

Shang Kexi nodded.

"In addition to sending elite soldiers to stay in Haizhou with you, I will also give you a city construction expert."

Yang Chengying said and clapped his hands.

A middle-aged man walked in.

"This is a city-building talent introduced by Inspector Yuan, whose surname is Lu Mingshanji."

Yang Chengying introduced the man to Shang Kexi: "He was introduced to me after I sent someone to pass on the information to Inspector Yuan, and after Inspector Yuan heard about my strategy. ”

"Mr. Lu, please advise."

Shang Kexi saluted respectfully.

Lu Shanji also returned the salute: "Please give me more advice in the future." ”

"Both, if you are polite, you will have the opportunity to say it in the future, and I will now focus on the construction of Haizhou City."

Yang Chengying said: "The area around Quang Ninh has been effectively abandoned by Jianyu, so our focus is still on the north. Before I received the order to come in, I would still stay in Haizhou.

But the main commands are given to you, do you understand? ”

"Understood."

Shang Kexi has already adapted, and Lu Shanji is a little nervous after all.

Yang Chengying nodded, and began to emphasize a series of requirements for building the city, as well as the details.

Last time, Yang Chengying stayed in Haizhou City, so he paid attention to the situation in Haizhou City.

After returning, he told Mao Yuanyi, an expert in city construction, about these situations.

Mao Yuanyi had also been to Haizhou City once before, and combined with Yang Chengying's ideas, he drew a map of city building.

Yang Chengying took this picture and asked Lu Shanji's opinion.

The two sides discussed the details of the construction of the city fiercely.

It wasn't until the afternoon that the discussion ended.

Yang Chengying left them for dinner, and when he saw that it was getting late, he returned to the inner courtyard.

The princess was lying on the princess's chair, covered with a thick quilt, holding a book in one hand, dangling to read.

"I'm back."

She heard footsteps and looked up.

"Hey, the day is finally over."

Yang Chengying leaned over to the princess and sat on a small stool.

The princess looked at his face and said with a smile: "I have never seen you so sad, isn't it very serious?" ”

"It's better that you don't know about this."

Yang Chengying sighed and said, "If you hear too much, you will only be tired." ”

"Looks like bad news." Zhu Huixian's face sank.

"Yes. It's going to be a history-changing event, and I think the rest of the day will be spent in intense work. ”

Yang Chengying stroked the princess's hair: "But I hope you don't worry about these things and give birth to a child peacefully." ”

Prenatal and postnatal depression can be terrible!

Zhu Huixian smiled slightly: "From my birth to this world, many things will happen before or after, and I will face it calmly." ”

"That's good." Yang Chengying breathed a sigh of relief in his heart.

He thought to himself that this might be the only warm time he had for a long time in the future.

The thought of seeing something happen with my own eyes inevitably makes me feel uncomfortable and apprehensive.

is as nervous as he is, as well as Huang Taiji.

When Liu Xingzuo and Li Yongfang left, he realized that he was simply three hundred taels of silver here, and clearly told the other party his intentions.

But the arrow is on the bow, and it has to be sent!

In addition, he believed that at such a young age, Chongzhen would not believe Yuan Chonghuan and Yang Chengying's warnings, only as if they were unfounded.

In addition to comforting himself like this, he didn't seem to find a more suitable reason to comfort himself.

It's up to you to see what the future holds!

The first year of Chongzhen (1627), the second day of the first month of the second year of Dajin Tiancong.

Historically, the Battle of Ningjin occurred at the beginning of this year, and Zhu Youxiao died in August.

But the timeline fluctuated.

What hasn't changed is a "big bet" on the future of a generation of heroes, and for some reason his gambling heart is more determined!

Daming Jingshi, Liaoxi and Jinzhou Town, Mongolia, and Dajin will be involved in the big war, which kicked off.

Because this year is the year of Ding Mao, and it happens to be the Year of the Rabbit, it is called the change of Ding Mao.
