When Hong Chengchou arrived at the Hairadu camp, the news of the fall of Xi'an had already spread, and he had to concentrate the 50,000 soldiers gathered along the way, plus the 30,000 main forces of Guyuan Town, between the Zhengqi camp and the Hairadu camp.

In front of the guards, he smiled with a smile on his face, but his heart was half cold: Li Zicheng is going east to Longshan, that is his old camp, and as the governor of the three sides, he can't do it if he doesn't want to.

Although he was determined to die, the combat effectiveness of the Mandate of Heaven Army, he had learned in Guguan, tens of thousands of troops, almost all of them were wiped out, if it wasn't for spending a lot of money to buy the prison army...... Fortunately, it was only the loss of the division, and the land east of Guguan was still under the control of the Shaanxi Army.

For the sake of safety, he sent an order to Ma Shilong, the chief soldier of Ningxia Town, to be ready to reinforce the Hairadu battalion at any time.

80,000 troops, whether they can defeat Li Zicheng, Hong Chengchou is really lacking in confidence, I don't know how many soldiers and horses Li Zicheng on the opposite side has dispatched this time.

In order to find out the message of the Mandate of Heaven Army, he sent a messenger to Li Zicheng, asking Li Zicheng why he was treacherous and Chen Bing Longshan.

Li Zicheng took the letter in the messenger's hand, and immediately became happy, Hong Chengchou's tens of thousands of troops, not thinking about fighting, but writing a letter to himself, can the letter be able to quell the thieves?

This battle with Dai Junen is not a unilateral treachery by the Mandate of Heaven Army, which is a vain attempt to change the status quo on the border between the two sides. In fact, Hong Chengchou and himself raised troops almost at the same time, that is, neither side abided by the agreement reached in Guguan!

Li Zicheng also got the message from Wang Anping after sending troops, and they were just each other.

With such a black cauldron, Li Zicheng naturally wanted to throw it to Hong Chengchou.

He immediately wrote a letter to Hong Chengchou, refuting Hong Chengchou's accusations, and instead asked Hong Chengchou why he let Dai Junen attack Lanzhou in a vain attempt to squeeze the living space of the Heavenly Mandate Army.

Hong Chengchou received the reply, and sighed in his heart, it seems that he has lifted a stone and smashed his feet, stealing chickens and rice, maybe he shouldn't stab Li Zicheng's hornet's nest!

But after Li Zicheng took Jingyuwei in one breath, he also took Xi'an, which is unbearable, he has already concentrated 80,000 troops, as well as Ma Shilong's reinforcements, once the deployment is completed, it is necessary to solve the Mandate of Heaven Army in a battle, and eliminate the future troubles forever!

Hong Chengchou felt more and more that the Mandate of Heaven Army would become a climate for a long time, compared with other thieves and rogues, Li Zicheng was more terrifying, and the combat effectiveness of the Mandate of Heaven Army was even stronger, and he might not be able to completely eradicate the Mandate of Heaven this time.

But now is the chance to eradicate the Mandate of Heaven, perhaps the only chance!

On the one hand, Hong Chengchou stepped up the deployment of the army, and on the other hand, he sent a letter back to Li Zicheng, asking him to withdraw to Lanzhou and restore the border between the two sides before the war.

When Li Zicheng received the reply, he sneered slightly, Hong Chengchou violated the agreement, and he didn't even mean to apologize, but let himself withdraw the army, is this playing himself as a child?

Xi'an can be abandoned, but Jingyuwei has been changed to Jingyuan County, together with the Dala Chi Fort and Ganyanchi Fort to the east of it, he will never let go, even if there is a large-scale war for this, he will not hesitate to do so!

On the one hand, under the guidance of the surrendered troops, Li Zicheng blocked all the road intersections, and on the other hand, he concentrated Li Ji's troops and the western part of Bada near Xi'an, relying on Xi'an, speeding up the construction of fortifications, and even using mountain artillery and gunpowder bags, ready to fight with Hong Chengchou at any time.

Letters can only delay time, solve problems, or need strength!

After everything was arranged, Li Zicheng sent a messenger to tell Hong Chengchou: If you do something wrong, you can't push it off, you will always be punished, Jingyuwei and Xi'an, the Mandate of Heaven Army will definitely not return, and it should be a punishment for his treachery as the governor of the three sides!

Hong Chengchou read Li Zicheng's letter, and his face turned pale with anger, and his hard beard trembled one by one.

In any case, Xi'an must be recovered, otherwise, the Mandate of Heaven Army will have many passages to advance eastward, threatening the various guards under Guyuan Town at any time, he sent a messenger, preparing to march tomorrow, and take Xi'an first.

"Lord Overseer, the Ministry of War is urgent!"

Hong Chengchou was taken aback, at this time, what will happen to the military department? Could it be that the Ministry of War knows about the Mandate of Heaven?

No way! He immediately denied that Li Zicheng had sent troops to Jingyuwei, and he had just learned that the military headquarters was far away in Beijing, and it was impossible to get the information so quickly.

He opened the paperwork of the military department, and suddenly it was like taking a bath on Mount Everest, and it was cold from head to toe in an instant.

It turned out that after the main force of the thieves entered Shanxi, under the siege of Cao Wenzhao, Zuo Liangyu and He Renlong, they could not stand on their feet, and gradually turned to Beizhili to threaten the Beijing Division.

The Ministry of War ordered Hong Chengchou to immediately organize an army to intercept and block the thieves east of the Yellow River.

Hong Chengchou couldn't help but scolded Zhang Fengyi, the secretary of the military department, he, the governor of the three sides, the main target was the Mongols in the north, and now he was in Xi'an to conquer Li Zicheng, and there was already additional military affairs, didn't Shaanxi still have the governor Chen Qiyu?

But scolding and scolding, he did not dare to disobey the military orders of the Ministry of War.

Hong Chengchou really wronged Zhang Fengyi.

Zhang Fengyi also had no choice, so he ordered the requisition of the Shaanxi army, the thieves could not be extinguished, Chongzhen summoned him into the palace, and criticized him, and Zhou Chunxiu, Yushi Ge Zhengqi, etc., impeached Zhang Fengyi for dereliction of duty on the grounds that the war was unfavorable.

Zhang Fengyi resigned several times on the grounds of "old age and infirmity, and incompetently in court official duties", but Chongzhen did not allow it, and he was forced to make a show, and transferred troops in various parts of the north to encircle and suppress the main force of thieves, and made an all-out attack.

Hong Chengchou was still hesitating, whether to take advantage of the concentration of the main force of the Shaanxi Army to fight a battle with Li Zicheng, at least let Li Zicheng spit out of Xi'an and stop for a while.

Two hours later, Xu Dingchen, the governor of Shanxi, sent a message that the thieves suffered heavy casualties under the full encirclement and suppression of the Shanxi army, but their main force turned westward and asked the overseers to send troops to stop them and work together to eliminate the thieves.

Hong Chengchou couldn't help but scold, if the thieves suffered heavy casualties, how could they say that the main force was there? Most of the time the Shanxi army drove the thieves away......

The disappointment was not over, and soon after, Ma Shilong, the chief soldier of Ningxia, sent a message: The Mongols outside the Hetao did not retreat, and the army really did not dare to move inward!

Hong Chengchou's head is big, the order of the military department and the request of Shanxi make him feel that the form of thieves is in danger again, Shaanxi has not yet been quiet, and then the main force of thieves will be ushered in, and he, the governor of the three sides, may fall to the end of his predecessor Yang He.

Ma Shilong, as the main backup, did not dare to leave his post without permission...... In the case of Hetao, Hong Chengchou knew that under the fierce attack of the Mongols, the former commander-in-chief He Huchen was killed in battle, and the imperial court had to use Ma Shilong, who was idle at home, a damned Mongol......

Li Zicheng is on the other side, what should I do?

If you want to fight with Li Zicheng, I'm afraid it's unrealistic, let's not talk about the victory or defeat, if the soldiers suffer too many casualties, how can they intercept the thieves in the east? Annoyed Li Zicheng, I'm afraid the battle won't be able to subside in a while.

Thinking of the combat effectiveness of the Heavenly Mandate Army, he couldn't help but gasp, it was his eternal pain to close the city!

If he is given enough time, plus sufficient troops and supplies, he is confident that he will destroy the Mandate of Heaven Army, however, the thieves are not only Li Zicheng's gang, in addition to the west, the thieves in the east are more mobile and influential, and the most important thing to solve at present is Gao Yingxiang and Zhang Xianzhong!

Hong Chengchou let out a long sigh, and the 50,000 army was assembled...... I'm afraid it's going to be cheaper this time.

The only way is to reach an armistice agreement like Guguan, maintain the status quo, temporarily stabilize Li Zicheng, and wait until Gao Yingxiang and the others have stopped, and then it is not too late to go back and clean up Li Zicheng.

Hong Chengchou immediately asked his guards to serve him and sent a long letter to Li Zicheng.

In the letter, he first reviewed the consensus reached by the two sides in Guguan, that the Shaanxi Army, like the Mandate of Heaven Army, maintained the stability of one side and ensured the smooth implementation of internal decrees in the territory.

The two sides can't talk about friendship at all, but under Hong Chengchou's pen, they have become like-minded and deeply friendly allies.

In the end, Hong Chengchou proposed that as long as the Heavenly Mandate Army withdrew to Lanzhou, the two sides could avoid fighting, and the subordinate brothers would no longer have to shed blood and sacrifice, and the two sides could continue to live in harmony.

Li Zicheng read Hong Chengchou's long letter, and couldn't help laughing, the Ming civil officials are so shameless that if the officers and soldiers and the thieves can get along, then the cat and the mouse, the angel and the devil, can also get along.

However, Hong Chengchou's proposal to live in harmony is in line with Li Zicheng's thoughts, and the only difference is the conditions.

In his reply, Li Zicheng fully agreed with Hong Chengchou's proposal to live in harmony and non-aggression with each other, and as long as the two sides could reach an agreement and maintain the existing territory, the Mandate of Heaven Army would no longer worry about the Manchurian capital camp in the east, let alone harm King An and King Han in Pingliang Mansion.

Hong Chengchou was taken aback when he received the reply, Li Zicheng ostensibly agreed with most of his ideas, but he did everything he could to threaten in the letter.

He originally expected that even if Li Zicheng didn't spit out Jingyuwei, he should spit out Xi'an, which was close to the Manchurian camp, but Li Zicheng was taking the matter of King An and King Han, and he really wanted to blackmail him.

Knowing that it was a threat, Hong Chengchou had nothing to do, King An and King Han were both clans, once something happened, he, the governor of the three sides, would lose his head, and he would not be able to extinguish the emperor's anger.

This Li Zicheng is really not simple, when Gao Yingxiang and they stop, they must meet him well.

Hong Chengchou knew that Li Zicheng could write this kind of letter, there must be a master in the army, and it would be useless to say more, besides, the military situation would not give him enough time!

He immediately replied to Li Zicheng, it was not easy for the two sides to form friendship in the battle, and on the basis of the previous cooperation between the two sides, he completely agreed with Li Zicheng's suggestion, the two sides should maintain the status quo, not attack each other, and if there is a dangerous situation, they also need to help each other.

This time, Li Zicheng also happily agreed to all of Hong Chengchou's proposals, and since the consolidation of the pass, the two sides have also reached an armistice agreement on the northern front.

Unlike the formal agreement, the Shaanxi Army has a Mandate of Heaven Army, and there is no special agreement, and the two sides have not agreed on the way to implement it, everything depends on the self-control of both sides.

If this is an agreement, it is more of a delicate balance.
