In Wang Feng's opinion, since Yelu Sha, who is the general of Zuzhou, is so strong and backbone, and the Khitan defenders of Zuzhou have also shown extreme bravery in the previous battles, then the two thousand Khitan troops guarding the mausoleum of Yelu Abaoji will naturally be stronger and more heroic. In addition, the terrain of the mausoleum area is easier to defend and difficult to attack than that of the ancestral governor's overlordship, so when he left the ancestral governor's overlordship, he was mentally prepared for another big battle with the Khitans in the ancestral tomb. Of course, psychological preparation is psychological preparation, and as a routine process before the war, persuasion to surrender is still indispensable. Although he did not hold out any hope that the Khitans would surrender, when the Khitan general in charge of guarding the ancestral tomb said that he needed time to consider and discuss, Wang Feng agreed to the other party's request and gave the other party an hour to make a decision—even if he did not see the slightest fear or retreat from the Khitan general's face.

Needing time to consider whether to surrender was naturally just a tactic for the Khitan general who guarded the tomb to delay time, as a close subordinate of Yelusha, after learning that his master had been blown to nothing in the stone chamber of the inner city of Zuzhou Changbacheng, he was already determined to fight the Zhou army to the death and never surrender. It's just that people think differently from person to person in many cases. Just when the Khitan general decided to die for his country and repay Yerusha for cultivating him, the two small generals under his command who each led a thousand-man team (Khitan military rank) believed in the Han people's saying that "those who know the practice are handsome". Faced with the situation that the general trend has passed, they are not willing to risk their lives for the Khitan court that is about to run out of gas and the mediocre emperor who only knows how to drink, sleep, and hunt. Therefore, when the letter of persuasion of the Zhou army was shot into the parapet wall of the mausoleum area, the two little generals pondered their own thoughts. After some private communication and exchange with their boss, the two quickly reached an agreement and immediately began to implement their own "self-help" plan.

So, half an hour after the Zhou army issued an ultimatum, the two Khitan generals invited their superiors to their accounts in the name of discussing the military situation and arranging defenses. They first expressed their opinions and talked about how to deal with Zhou Jun, which successfully distracted the attention of their superiors. Immediately, he took advantage of the other party's unpreparedness to make a black hand, and at the same time inserted the dagger hidden in his arms into the back of his boss's heart. The henchmen and soldiers of the two also acted at the same time, first killing several personal soldiers who accompanied the Khitan general, and then killing several of the former's cronies in the army with lightning speed. In this way, in just a moment, the two little generals took control of the soldiers and horses guarding the mausoleum, and opened the gate of the mausoleum area before the last time stipulated by the Zhou army, and surrendered to the Zhou army outside.

Seeing that the expected big war and vicious battle did not appear, and he only relied on a letter of persuasion to take the ancestral mausoleum area bloodlessly, Wang Feng couldn't help but be a little surprised and a little emotional, and secretly sighed that people's hearts were really the most difficult to figure out.

Although it is a crosser from a thousand years later, some things in the bones of the Chinese have not changed, and the idea of respecting the dead is also deeply rooted. Therefore, before leading the army back to the capital governor Bacheng to join Yang Xin, Wang Feng left a regiment of the "security army" to protect the safety of the mausoleum area, and strictly ordered that no one on his side was allowed to enter the mausoleum area without permission, let alone destroy a single grass and tree here.

On the twelfth day of the fourth lunar month of the seventh year of Jianlong, after pacifying the people around the city of Governor Haozu and leaving a regiment of the "Security Army" and a temporary regiment of more than 1,000 people composed of local Han people to train troops to garrison the city, Yang Xin and Wang Feng led the main force of the Left Route Army of the Northern Expedition back to Linhuang City.

Although in addition to Linhuangcheng and Zuzhou, there are also Ningzhou and Yuzhou in the northeast, Huaizhou and Qingzhou in the northwest, Yikun and Raozhou in the southwest, and other prefectures and counties in the jurisdiction of Linhuang Prefecture that have not yet been captured. However, on the one hand, the location of these states and counties is scattered, and it is inconvenient for large troops to attack back and forth; On the other hand, in addition to Huaizhou, Qingzhou, Yikun Prefecture, and Raozhou, which are still of some scale and tens of thousands of people, the others are the places where the Khitan royal nobles raise horses and graze, and generally only a few hundred to more than 2,000 Han or Bohai herdsmen are stationed. The seizure of such a place is redundant to say that it is the main force of the Left Route Army of the Northern Expedition, and that is, the "security army" sent to a regiment.

Therefore, after returning to Linhuangcheng, the Left Route Army of the Northern Expedition was divided into four. Wang Feng led the first and second battalions of the third regiment of the first composite infantry division of the "Flying Dragon Army", the first infantry regiment of the "Security Army", and two cavalry battalions of about 4,000 people to the north to seize Huaizhou, Gyeongju and other prefectures and counties; Zhao Chen, deputy commander of the 1st Synthetic Infantry Division of the "Flying Dragon Army", led the cavalry regiment, the 3rd Infantry Regiment and 3rd Battalion of the Division, and a 1st Infantry Regiment of the "Security Army" with about 5,000 men and horses to the south, sweeping Yikun Prefecture, Raozhou, Fengzhou, Songshan Prefecture (Songshan Prefecture in Linhuang Prefecture instead of Songshan Prefecture in the former Khitan Zhongjing Province previously captured) and other prefectures and counties; Wu Peng led a company of the "Flying Dragon Army" and a "Ranger Battalion" and a cavalry battalion and an infantry battalion of the "Security Army" to the northeast to seize Ningzhou, Yuzhou and other prefectures and counties.

Originally, according to the pre-war plan and the original intention of Yang Xin, the commander-in-chief of the Left Route Army of the Northern Expedition, Ningzhou and Yuzhou, which had only 1,800 herdsmen, could only send at most one battalion commander of the "Flying Dragon Army". But on the one hand, because the series of battles of the Left Route Army since the Northern Expedition were just staff officers who assisted the command of the two brothers, he did not show much real skills, and the most intense battle of the Zuzhou Governor to dominate the city was even more guarded in Linhuang City, and he didn't even see it, which made Wu Peng, who was the chief of staff of the Left Route Army of the Northern Expedition, feel that his first expedition since the crossing was very unpleasant. Seeing that after taking several surrounding states and counties, the Left Route Army would no longer have any battles, Wu Peng was naturally very unwilling, and repeatedly proposed to Yang Xin and Wang Feng that he hoped to personally lead the troops into battle and sweep through Linhuang Mansion - according to the pre-war arrangement, Wang Feng would lead the troops to fight in the action of subduing the grassland tribes, and he who also wanted to kill a happy one It was obviously impossible for him to give up his position to Wu Peng.

Second, it is also considering that there are no Khitan troops and horses around Linhuang Mansion now, even if it is only a partial attack, there will be no danger. In addition, Wu Peng is a close confidant of the eleventh brother Qian Yuanshan after all, and this expedition is his first time participating in a large-scale battle, if he, the commander, blindly disagrees with the former's request and does not let him lead the troops into battle alone, it will make others misunderstand that he is deliberately suppressing his brother, so as to take all the credit on his head, it will not be beautiful.

Therefore, after thinking about it several times and discussing it with Wang Feng, Yang Xin still agreed to Wu Peng's request and promised him to lead his division to sweep the Linhuang Mansion. As for which way to lead, there was no suspense. The three people, those who went north to Huaizhou and Gyeongju were led by Wang Feng, and Wu Peng naturally couldn't compete with him. Because in the subsequent operation to subdue the grassland tribes, the exit of the grassland assault cluster of the Left Route Army of the Northern Expedition was in Gyeongju. As the commander of the assault group, Wang Feng needed to familiarize himself with the terrain and environment there, even if he wanted to, he couldn't. Ningzhou and Yuzhou in the northeast are just two small states with thousands of households, and the Zhou army that went to sweep was only more than 1,000 people, even if the Khitans in these two states resisted stubbornly, there would not be any big battles. Therefore, no matter how you look at it, the way south to Yikunzhou and Raozhou should be Wu Peng's first choice.

However, the problem is that in addition to providing operational command assistance to Yang Xin and Wang Feng as the chief of staff of the Left Route Army of the Northern Expedition, Wu Peng is also part-time responsible for the logistics supply of the army and the transportation of military baggage. Judging from the current situation, it will probably take no more than a month for the Central Route Army to conquer Changchun Prefecture and complete the "Spring Bowl", and then it will begin to subdue the grassland tribes. Once the Zhou army began to enter the grassland to fight, then whether Wu Peng wanted to or not, he had to return to Linhuang City to assist Yang Xinlai in supporting and supporting the combat operations of the Left Route Army's grassland assault group. However, Yikun Prefecture, Raozhou, Fengzhou, Songshan Prefecture and other prefectures are scattered, and there are many mountains and mountains along the way, and rivers are criss-crossed, and it takes at least one and a half to two months to sweep around, and the two are obviously conflicting in time.

The northwest direction could not compete with Wang Feng, and the southwest direction was too late, Wu Peng helplessly found that he now had only one choice left - to lead more than 1,000 people to seize Ningzhou and Yuzhou, which together were less than 2,000 households. Although this result was somewhat unexpected, and he was very disdainful of this kind of small-scale battle, Wu Peng, who was originally full of interest and confidence, felt very depressed. But considering that he took the initiative to ask for the troops to sweep before, and after a lot of hard work, he got the approval of the twenty-fifth brother, if he gave up, he would probably be considered by the other party to be unreasonable, which was not conducive to the unity between the brothers. Therefore, in line with the principle of "no matter how small the mosquito's legs are, they are still meat", Wu Peng had to complain that he had not considered the problem comprehensively before, and on the other hand, he reluctantly accepted this only choice, and led more than 1,000 people to leave Linhuang City and kill Ningzhou, which was 240 miles away.
