Li Zicheng's actions and the news passed on by He Renlong instantly shocked the imperial court.

Kaifeng is not only the provincial capital of Henan, but also one of the most important towns in the north, Kaifeng is known as the ancient capital of the Eight Dynasties, the significance of the representation is very unusual, such an important town, once attacked by the Liukou, the impact is extremely bad, the emperor and the court will not allow such a situation.

Without much hesitation, the emperor, the cabinet, and the military department formed a unified opinion, demanding that Wu Fu, the governor of Henan, and He Renlong, the chief soldier, must strive to ensure the safety of Kaifeng Fucheng, and at the same time order Sun Chuanting, the governor of the military department and the governor of the five provinces, to lead a large army to aid Kaifeng Mansion, and strive to completely defeat Li Zicheng on the periphery of Kaifeng Mansion.

As for Zhang Xianzhong, who is stuck in Yunyang, it is not so important at the moment.

The battle between Sun Chuanting and Zhang Xianzhong has begun.

When the offensive just began, Sun Chuanting did not take a large-scale attack or a general attack, and his more offensive was tentative, after all, Zhang Xianzhong had made full arrangements inside and outside the city of Yunyang Mansion, and a rash attack could only cause heavy casualties and hit his own morale.

Sun Chuanting set up camp twenty miles away from the city of Yunyang Mansion and confronted Zhang Xianzhong.

Zhang Xianzhong arranged for the Liukou stationed outside the city, the number of which was about 50,000, these Liukou relied on the vertical and horizontal ditches to defend against the attack of the imperial army, and these dug ditches could not only stop the charge of the war horses, but also delay the charge of the sergeants.

At the beginning of the battle, the fierce and sharp artillery did cause heavy casualties and deterrence to the rogue.

Sun Chuanting did not blindly adopt the method of onslaught, and used a step-by-step approach to encroach on the positions deployed by Zhang Xianzhong, and every attack began. Sun Chuanting demarcated the key areas, concentrated artillery to bombard the key areas, and after a quarter of an hour to half an hour of bombardment, the infantry launched an attack, and at the same time, in order to ensure the smooth attack, Sun Chuanting also arranged for 20,000 to 30,000 sergeants to guard the left and right flanks. Prevent reinforcements from coming from the rogues.

Sun Chuanting's offensive tactics have had a good effect.

Zhang Xianzhong originally decided to use the criss-crossing ditches to defend against the attack of the official army, the key consideration was to prevent the cavalry of the official army from launching a large-scale charge, and the ditch can also defend against the attack of artillery to a certain extent.

However, what Zhang Xianzhong didn't expect was that Sun Chuanting was not in a hurry at all, taking one step at a time, and sometimes even for a defensive ditch with a radius of dozens of meters. A massive assault was launched, and shells rained down on these ditches, and the sergeants on guard were simply unable to defend against them.

However, Sun Chuanting took this steady and steady way, and Zhang Xianzhong was not in a hurry, even if he lost dozens of meters or hundreds of meters of ditches every day, Sun Chuanting really wanted to attack Yunyang Mansion City, I am afraid it would be a month or even two months later, and at that time. The tide of the war has long since changed.

Three days after the attack began, Sun Chuanting had already advanced nearly four miles in the direction of Yunyang Fucheng.

It was at this time. The situation on the offensive has changed.

Zhang Xianzhong ordered the righteous sergeants to dig a radius of ten miles of ditches, almost all of them were connected, and the division of troops was also very extensive, and after the three-day attack of the officers and soldiers, the sergeants of the righteous army also knew the law, once the officers and soldiers began to launch a large-scale bombardment of a certain area. The rebel sergeants would quickly evacuate, and when the artillery fire stopped, they would immediately enter the ditch and fight.

In this way, the officers and troops lost a large number of artillery shells, but the effect of the attack was not very good.

After artillery fire. The infantry of the official army began to charge, and the volunteer sergeant had entered the ditch, at this time the official army could not fire artillery, and the volunteer sergeant could rest assured and boldly fight with the official army to defend the position.

Sun Chuanting also discovered such a problem, from the fourth day onwards, the offensive of the army suffered repeated setbacks, the number of casualties continued to increase, the casualties in the battle for positions increased, and the role that artillery could play became smaller and smaller.

After getting the specific situation of the battle, Sun Chuanting immediately made adjustments and prepared to adopt the tactics of large-scale attack, that is, after the artillery bombardment, the attacking infantry was not limited to a specific position, and began to charge in all directions, striving to occupy more ditches in the shortest possible time.

Such an adjustment means that the artillery offensive is not concentrated in a certain place, but in full bloom.

The change in tactics has embodied the wisdom of the commanders, and Sun Chuanting believes that the timely adjustment of tactics will certainly achieve very good results.

For Zhang Xianzhong, who was sticking to the city of Yunyang, Sun Chuanting still admired a little, no matter what the reason, Zhang Xianzhong dared to stick to it, and dared to fight face-to-face with the imperial army, which was not simple.

Just when Sun Chuanting was confidently preparing to launch a large-scale attack, the sergeant sent by He Renlong arrived.

In the military tent.

Sun Chuanting and Wang Yongji's expressions are not very good-looking.

He Renlong did not have much knowledge, and the sergeants sent mainly dictated Li Zicheng's whereabouts.

The map on the table has clearly shown the choice made by Li Zicheng, a big red arrow, starting from Nanyang, extending to Yuzhou, Yexian, Xiangcheng, Xuzhou, Weishi, and finally pointing to Kaifeng Fucheng.

The battle of Yunyang has entered a critical moment, and it can also be said that it has entered a white-hot state, but at this time, Li Zicheng of Nanyang took action, and it was an action that exceeded everyone's expectations.

For a long time, including Chen Xinjia, Sun Chuanting, Wu Fu, Fang Kongzhi, He Renlong, Zuo Liangyu, Liu Liangzuo and other people's focus is in Nanyang, Runing, Xiangyang and Yunyang and other places, including Kuizhou in Sichuan, no one thought of Kaifeng Fucheng, the deployment of troops is also focused on these places, Huguang's Xiangyang and Yunyang are needless to say, Henan, the army led by He Renlong is deployed in Xinye and Xinyang and other places, after the imperial army recovered Xiangyang Fucheng, He Renlong's deployment made some adjustments, The troops were mainly stationed in the area of Xinye and Dengzhou to prevent the union between Li Zicheng and Zhang Xianzhong.

Li Zicheng chose to attack Kaifeng Fucheng.

This is tantamount to inserting a sharp knife in Sun Chuanting's heart.

Sun Chuanting had to make a choice, whether to continue to attack Zhang Xianzhong, who was holding Yunyang, or turn around and go north to aid Kaifeng Fucheng.

Sun Chuanting was already confident that he would defeat or even exterminate Zhang Xianzhong.

From the perspective of geographical location, Zhang Xianzhong's only escape route is to go north and unite with Li Zicheng, Shaanxi in the west is a forbidden place for the Liukou, and he does not dare to go at all, and Sichuan in the south, Qin Liangyu is ready, once the Liukou enters, he will encounter the encirclement and suppression of the imperial army and the white pole soldiers, as for the east, it has been recovered by the imperial court.

In terms of the deployment of troops, Sun Chuanting focused on the north to prevent Zhang Xianzhong from escaping in the direction of Henan.

Starting from Xiangyang Mansion City to the Battle of Yunyang, Sun Chuanting spent countless efforts and made too many preparations, and saw that the victory of completely destroying Zhang Xianzhong was in front of him, but there was a major accident.

The sergeant sent by He Renlong was taken out to rest after the report was completed.

Only Sun Chuanting and Wang Yongji were left in the Chinese military tent.

Sun Chuanting looked at the map for a long time and sighed slightly.

"Wang Jianjun, I think the army should not change its deployment, insist on fighting in Yunyang, completely defeat and exterminate Zhang Xianzhong, as for Li Zicheng's attack on Kaifeng Fucheng, you can order He Renlong to help, and at the same time we can suggest that the military department dispatch the border army in the direction of Datong, Shanxi, to quickly rush to the aid of Kaifeng Fucheng, and can also order the border army in Yulin, Shaanxi and even Ningxia to reinforce the ......"

After Sun Chuanting finished speaking, Wang Yongji shook his head slightly.

"Master Sun, our family knows your thoughts, that is, they want to completely exterminate Zhang Xianzhong, it has been five days, and the progress of the battle has been very good, but at this time, our family will also tell the truth."

"My lord is the secretary of the military department, the governor of the five provinces, on behalf of the imperial court responsible for the extermination of the Liukou, in case Datong, Yulin and even the border army of Ningxia could not be rescued, resulting in Kaifeng Mansion City being taken by Li Zicheng, who will bear this responsibility, I am afraid that the lord and our family have an unshirkable responsibility."

"There is another point, the battle to attack Yunyang Mansion City is indeed going well, but the battle situation has changed, how long can Zhang Xianzhong be defeated or even exterminated, my lord can't say the exact time, and our family has no bottom in our heart, if the cabinet and the military department ask, can you give the exact time."

"Since Li Zicheng decided to attack Kaifeng Fucheng, needless to say that this is also a decision made after consultation with Zhang Xianzhong, the two Liukou have begun to fight together, we think that the reason why Zhang Xianzhong stuck to Yunyang Fucheng and did not evacuate to Sichuan is to attract the attention of the army, so that the army can fall into the battle of Yunyang Fucheng, so that Li Zicheng can take Kaifeng Fucheng......"

Wang Yongji told the truth, a rare truth, perhaps involving his own safety, Wang Yongji did not have any cover-up, and directly pointed to the vital place.

Sun Chuanting was silent, he knew very well that his own tactical arrangement had been miscalculated, the joint and coordinated operation between Li Zicheng and Zhang Xianzhong burst out with huge power in an instant, allowing him to reach a dilemma, even if he decided to reinforce Kaifeng Fucheng, it was not necessarily a good choice, in case Zhang Xianzhong followed into Henan to fight, he would face a situation that was difficult to take care of, Li Zicheng and Zhang Xianzhong's two-way army could surround more than 100,000 troops under his command.

When it really comes to such a situation, it is difficult to say clearly the progress of the battle.

Since there is a union between Zhang Xianzhong and Li Zicheng, then the news that Li Zicheng began to attack Kaifeng Fucheng came, Zhang Xianzhong would definitely resist frantically, and the battle of Yunyang would really become a protracted war and a war of attrition. (To be continued......)
