Maybe it's the aftermath of the last "horse to take Haiyang", maybe it's the chain reaction brought about by the defeat of the Khitan army in the Battle of Youyun, maybe it's the murderous spirit shown by the two special forces of the "Ranger Battalion" and the "Wolf Tooth Battalion", or maybe it's the sharpness of the firearms they use, whether it's because of Weishenme, anyway, when Muttel led the troops to the city of Haiyang, the seat of Runzhou, put the cannon on the ground, and fired two cannons at the head of the city, the defenders in the city opened the city gate. The state and county officials and guards went out of the city and knelt on the ground to beg for Mutel. Seeing that he had only fired two cannons to facilitate the surrender of Kaecheng, Muttel felt a little disappointed while being a little proud. In his opinion, it is naturally good to be able to surrender without a fight, but if it is like this all the way down, it is not necessarily a good thing for the army under his command. First, the surrender of the enemy army without a fight may make one's subordinates despisy the enemy, and once they encounter an opponent who dares to fight with them, they will inevitably be uncomfortable, and they will be caught off guard by the opponent, and thus defeated. Second, the enemy army is vulnerable, and naturally it will not be able to make its own team be baptized and tested by the fire, and in the long run, this army will slowly wear off its own spirit in comfort and comfort, and will no longer be the kind of bravery and fearlessness in the previous battles.

Therefore, after taking Haiyang City again, Muttel only stayed in the city for one night to replenish some provisions, and the next day he led his troops to leave Haiyang and walked all the way north along the seaside road, passing through Qianzhou and Laizhou, until he reached Xizhou Seaside City. Although all three cities were eventually breached by Muttel's troops, the resistance of the defenders in the city became more and more stubborn, from the two cannons of Haiyang City to the one-day capture of Xizhou Seaside City, Muttel and his special forces faced more and more resistance - after all, the Bohai soldiers guarding this area were still quite good. Not only did the siege take more and more time and consume more and more ammunition, but the troops also began to suffer certain casualties. However, Muttel is not very concerned about this, on the contrary, he is happy with the situation. In his opinion, with acceptable casualties and attrition, it is still very cost-effective to not only realize the order given to him by the committee and the military department to harass the states and counties of the Liao State north of the Great Wall so that the other party can take care of Zeng Zhilin's troops who are recovering the lost territory in the eight states behind the mountains, but also to experience the most elite Liliang in the crossing team under his command through this series of battles. In particular, after his actions were affirmed and supported by the Committee and the Military Department, the scope of his activities became even larger. From Runzhou Haiyang City, which is only 30 miles away from Yuguan (Shanhaiguan), to Jinzhou Yongle City, which is 400 miles away, and even Dading City, Dading Mansion in Zhongjing, Liaoguo.

Of course, compared with cities such as Haiyang City and Seaside City, Jinzhou, Dading and other important towns have high moats, tight defenses, and a large number of men and horses, and the 1,500 or so people under the command of Muttel alone can only cause certain casualties and psychological blows to the other party at most, and it is still impossible to conquer such a large city. Therefore, from the moment he left Laizhou Laibin City and continued along the coast to the north, Mutel began to search for non-Khitans along the way who were either dissatisfied with the Khitans, or were poor and had no way to live, or wanted to take advantage of the opportunity to gain some benefits, and let them join his ranks, using the weapons and horses in the captured cities along the way—some of the new soldiers themselves had horses themselves—to make them the vanguard of his troops, and to attack and plunder the cities along the way. As a result, the number of troops under Muter's command became more and more numerous, and when he arrived at the Yongle City of Jinzhou, his troops had reached more than 10,000 people.

Although the Khitans sent reinforcements from Linhuang Prefecture in Shangjing and Liaoyang Prefecture in Tokyo, Mutel's troops took the initiative to evacuate Yongle City in Jinzhou to prevent the enemy from being attacked on their backs, the devastated southern wall of Yongle City and the heavy casualties of the defenders still shocked the Khitan court. So much so that Yelu Jing, who had just returned to Shangjing Linhuang Mansion from Zhongjing Dading Mansion, was making every effort to deal with those political enemies who were ready to move because of his defeat in the Sixteen Prefectures of Youyun, and who had plots against his throne and had ill intentions, had to draw troops from many sources, on the one hand, he ordered Tokyo Province to send troops to reinforce it, and on the other hand, he sent the only general who had retreated in the Battle of Youyun and was now helping to quell the rebellion by his side, and then set out again to destroy—or at least expel the so-called force that had made a mess of Zhongjing Province." The Shadow Cloud Rebels". Since the retreat of Juyong Pass, Yelu Tartlie, who has always been regarded by the courtiers and the central courtiers, especially the military generals, as timid and afraid of war, and lacks the minimum courage of the Khitan soldiers, also wants to use this opportunity to eliminate this Han army, which is too deceitful and has no more than 1,000 regular soldiers, so as to justify his name and be ashamed of Daliao. …,

It's a pity that Muttle, who is very cool-headed and sober, doesn't want to give Yelu Tart Lie a chance to "take revenge" at all, as soon as he gets the news from the "Dark Feather" channel that Yelu Tart Lie led 30,000 troops to the south and wants to fight to the death with himself, and there are also a large number of Khitan troops from Tokyo Road to aid Jinzhou, he immediately changed Jihua to conquer Jinzhou, led the army out of the Jinzhou battlefield, turned to the southwest, passed through Anchang, Yonghe, and entered Longshan City in Tanzhou. Just when Yelu Tartlie, who led the Khitan army and followed behind, thought that his opponent was going all the way south and back to the Great Wall, Muttel turned again and turned northwest, passing through Yuzhou and Zhongcheng to reach Zhongjing Dadingfu.

Although the city of Dadingfu is high and deep, and there are heavy troops stationed, considering the sharp firearms in the opponent's hands, Yelu Tart Lie still did not dare to slack off, and hurriedly led the army to chase after him. But Mutel's wave of the army to Dading Mansion was just a false shot, and when Yelu Tartlie's department chased him to Dading Mansion, he had already led his army south, through naturalization, attacking Zezhou, and then turned westward, and turned around in Bei'anzhou, looting a large amount of grain and grass outside Xinghua City that had not yet had time to be transported, and then he was still unable to withdraw his troops to Gubeikou Pass for rest, and together with the brothers of the Military Department and the Intelligence Department who had already received his telegram there, they conducted the necessary examination and screening of the new army of more than 20,000 people who had recently been snared. In order to prepare for the next exit operation. And Yelu Tartlie, who was led by Mutel by the nose and turned around in Zhongjing Road, although he was extremely aggrieved and depressed in his heart, he still did not dare to take a step forward after leading the army to ten miles outside the Gubeikou Pass, nor did he dare to stay longer, and hatefully scolded the other party's commander in his heart for a few words, and then he collected his troops and returned to Shangjing in despair, and went to confess to his emperor.

Jereh was depressed on his side, but Mutrel was elated. According to preliminary statistics, this time, he led the "Ranger Battalion" and the "Wolf's Tooth Battalion" out of the pass to carry out harassment operations for only 40 days, but at the cost of 125 casualties -- not including the newly expanded troops -- he not only achieved the major results of conquering 15 large and small enemy cities, annihilating 45,000 enemy troops, expanding more than 20,000 troops, and seizing a large amount of grain and grass, but also successfully completed the task of harassing the Khitan army entrusted to him by the committee and the Military Department, so that it could not hinder Zeng Zhilin and Yang Xinsuo's troops from recovering the eight prefectures behind the mountains.

Both the committee and the military department spoke highly of Muter's victory, and the meritorious personnel in the battle were also recorded. Of the more than 20,000 new troops brought back by Muttle, nearly 15,000 were retained after being screened by the Ministry of Military Affairs and the Ministry of Intelligence, and after fully respecting the wishes of the other side. Among them, about 8,000 people have become tenants of the major farms of the crossing team, men from various shops, and miners from various mines, and the remaining more than 7,000 people have joined the "security army" - now the "Flying Dragon Army" is only open to tenants, men, and craftsmen who have served the crossing team for more than two years, and these new people are not eligible to join.

It is worth mentioning that of the 7,000 Xinding who joined the "Security Army", 5,000 Han Chinese were assigned to the original regiments to supplement their losses in battle, and the 11th Regiment of the "Security Army" was newly formed. The other 2,000 Xi and Bohai people were used separately and became the first members of the newly formed independent regiment of the "Security Army." Of course, in order to more effectively control these new recruits and enable them to integrate into the armed forces of the crossing team more quickly, the two newly formed regiments, from the regiment commander to the squad leader, from the metropolitan supervision envoy to the supervision of the principal positions at all levels, and the deputy positions in the supervision system, are all held by the backbone of the former "Security Army" and even the "Flying Dragon Army" regiments.
