Hearing what Wan Yuan Ji said, everyone, including Zhang Jiayu, was silent - Jin Shenghuan had a large number of Hongyi artillery, so after the destruction of the Soakou Fortress, the Ming army was bound to fight a decisive battle on the west bank of the Ganjiang River and the Qing army crossing the river.

Jin Shenghuan's main force has two major sources, one is the surrender of the Ming army he brought from Nanjing, and the combat effectiveness is average. And more than 20,000 people are the original elite who are attached to him. These people followed Li Zicheng to rob half of the Ming Dynasty, fought with the Ming army and the Qing army dozens of times, and those who can survive until now are all ruthless characters who crawled out of the pile of dead people! The strength of combat effectiveness is far from being comparable to that of the Ming army under Yang Tinglin.

And Jin Shenghuan's deputy general Wang Deren was also a fierce general under Li Zicheng, a native of Liaodong, who was extremely fierce. In the first year of Longwu, he led hundreds of cavalry from Jiujiang, defeated the main force of the Ming army in Nankang and Nanchang many times, killed all the way to Linjiang, and broke through more than 700 miles in a month to capture four state capitals in Jiangxi!

In the face of such a strong enemy, if there is no fortress to rely on, even if Wan Yuan Ji leads his troops back to defense, it will be difficult to parry. Of course, if there is a battalion of elite soldiers of King Chenzhou to participate in the defense, there will be a chance to resist the offensive of the Qing army.

Su Chengyu frowned, after Gao Jinku's main force was annihilated in Fuzhou, Jin Shenghuan's plan to attack Ganzhou on two roads had failed, and now he would concentrate all his forces to capture Soakou. Defending against soap mouths is indeed an urgent need.

However, if the fighter plane in the northeast of Jiangxi is lost, and the Qing army in Huizhou moves south, it will have to pay a hundred times more if it wants to recapture Guangxin.

What is the trade-off?

"From Jin Shenghuan's standpoint, how does he think the Ming army will be deployed?" He asked suddenly.

"Jin Shenghuan is well aware of the importance of Ganzhou." Zhang Jiayu said, "Now that he is concentrating his forces to storm Saokou, it should be expected that our army will mobilize all forces to defend Saokou." ”

Su Chengyu tapped his fingers on the armrest of the chair and said slowly: "Then we might as well do the opposite." ”

"The other way around?" Everyone looked at him in amazement, waiting for the next step.

"Taking advantage of the fact that the Qing army was gathered in Soakou and the troops in other places were empty, the main force of our army quickly attacked Jianchang and Guangxin, and even took Raozhou and Nankang in the northwest in one go, forming a situation of encirclement of Nanchang Mansion."

"Never, never!" Wan Yuan Ji waved his hand again and again, "Even if you don't fight, it will take half a month for the army to reach Guangxin." When I return to the army, it will be a month later. At that time, don't say soapy mouth, even Ganzhou Mansion ......"

"Wandutang, don't worry, what if I have a way to make Jin Shenghuan unable to attack the soap mouth within two months?"

"Is what Your Highness said true?"

Su Chengyu smiled mysteriously, "There is something called fairy stone powder. Use it to build a fortress at the Soapmouth Fortress to ensure that nothing goes wrong. ”

The others' eyes widened in disbelief......

Half an hour later, the congregation will make a decision.

Wan Yuan Ji led the men and horses of the headquarters to escort the prisoners, and returned to Saokou with great fanfare, and at the same time publicized everywhere, saying that Yang Butang ordered all the Ming troops in Jiangxi to assemble in Saokou on the same day, and prepare to fight to the death with Jin Shenghuan.

The Jiezhong Xi Division was responsible for recovering the central and southern parts of Jianchang Province, where there were no large Qing troops, and the Jiedu Division had enough troops to deal with it.

The soldiers of the king of Yongning surrounded the southern city where the Jianchang Mansion was located, and annihilated the remnants of the Gaojin Warehouse here, and decided whether to go north or not according to the situation.

The king of Chenzhou directly attacked Guangxin Mansion in the north, and only Ke Yongsheng under Jin Shenghuan gathered three or four thousand troops here, which was not the opponent of the Dragon Guard. After taking Guangxin, the Longwei army will continue to move westward into Raozhou and Nankang, where the Qing army is weak and has many righteous troops to cooperate, and should be able to recover soon.

At this point, the Ming army has formed an encirclement of Nanchang Mansion, the core of Jiangxi, and the battle situation in the entire Jiangxi will become extremely favorable!

As for Zhang Jiayu's subordinates, they had been injured after the battle of Fuzhou, so they stayed in Jinxi to repair.

On Su Guansheng's side, everyone ignored his existence intentionally or unintentionally. He himself was self-aware, and took the only remaining 300 Xinwei troops to Ganzhou, in the name of reinforcing the defense of Ganzhou.

When Su Chengyu returned to his military tent, Wan Yuan Ji and Jie Chongxi came to visit one after another, both of them touted Su Chengyu first, and then tentatively asked if they could share some of the new bird guns equipped by the Dragon Guard.

To be honest, Su Chengyu was originally going to popularize the flint gun within the Ming army, but after hearing about Yang Tinglin's "sending" heavy artillery to Jin Shenghuan today, he immediately dispelled this idea.

If such a sharp weapon as the flint hair gun falls into the hands of Jianlu, with the weak combat effectiveness of most of the Ming army at present, I am afraid that the Ming defense line from Huguang to Zhejiang will collapse immediately.

Eventually, he politely declined their request, but promised to provide them with a more powerful bird. The two also left happily.

A moment later, Zhang Jiayu also came to Su Chengyu's tent and brought an officer with him.

After seeing the salute, Zhang Jiayu said: "In this battle of Shuangchen River, His Royal Highness swept away 15,000 Qing troops with a battalion of troops, like a wind and clouds, which really made the officials admire. ”

He bowed deeply, "The lower official thinks carefully, and only uses the more than 1,000 remnants of the army in his hands to make a difference, hoping to be able to saddle up the front and back with His Highness, and do his best." It would be a great fortune if you could learn the art of war battle formation of His Royal Highness. ”

Su Chengyu is overjoyed, Zhang Jiayu is a rare military talent! With 2,000 weak soldiers, he will be able to call for wind and rain in Jiangxi, and his military talent can be seen.

What is there to hesitate about, he hurriedly helped Zhang Jiayu up and said: "With the help of Yuanzi, the Long Weijun is really like a tiger!" "Yuanzi is Zhang Jiayu's cousin, and Su Chengyu heard other people call it a few days ago.

"How about Motoko stay with me as a staff officer of the Dragon Guard Legion?"

"Your Highness Xie will not give up, and you will do what you want!"

Su Chengyu corrected him with a smile and said, "In the Dragon Guard Army, I am only the commander of the legion, don't call me Your Highness." ”

"Yes, Commander." Zhang Jiayu immediately changed his name, and then he pointed to the officer behind him, "My lord, this is Chen Yi, who once organized the righteous army in Guangxin, and then followed his subordinates to fight in various places in Jiangxi. ”

Chen Yi hurriedly stepped forward to salute.

Zhang Jiayu continued: "Brother Yi is good at building cities. The fortress that the subordinate said was somewhat similar to the fort and the fortification, and he thought that he might be able to help. ”

Su Chengyu was overjoyed, he was originally going to let Song Yingxing build the fortress of soap, if there was a more professional candidate, it would be the best.

He immediately took out a pen and paper, simply drew a hexagonal bastion, and then explained the main points to Chen Yi one by one.

This Chen Yi is really familiar with earth and stone engineering, and quickly understood what Su Chengyu meant, and then told him about the specific construction method of building this "city".

Su Chengyu has no involvement in architecture, so he can only draw the structure of the fortress as clearly as possible, and the various parameters are marked in detail, and the rest has to rely on Chen Yi, an architectural expert.

In the end, he wrote down the cement, that is, the mixing ratio of immortal stone powder, and the method of use, on a piece of paper and handed it to Chen Yi, and asked him to return to the soap mouth with the Wandutang army and start construction as soon as possible.

Then Su Chengyu asked his soldiers to send an order to the Longnan cement field, and from now on, all the immortal stone powder produced will be transported along the Ganjiang River to Soakou.

The Longnan cement yard has been expanded twice, and now there is an output of 270,000 catties every three days, but he is still worried that it will not be enough, so he sent people to Ganzhou again, and ordered all the stocks and even the fairy stone powder that had just been sold to be sent to Soakou.

After all, in any era, military needs must have the greatest priority.
