Just when Dong Hu led his troops to fight the Mongolian army in Genting City, Huang Dagen's attack on Jintang City also made progress. Just as Jiagu Dragon chose to attack the city at night in ancient times, the Thunderbolt army, which also had the advantage of troops, also chose to attack at night, making the defense of the city exhausted. The fierce fighting finally made several defenders unable to hold on, and they tried to escape in the dark of night, but were caught by the Perak soldiers. According to the confessions of the deserters of these newly annexed troops, the defender of the city was none other than Yao De, who dedicated Genting City to the Mongolian army. Yao De was originally stationed in Genting City, and although he was a traitor, he also had talents. After Liu Heima transferred the 500 cavalry of Genting City to Chengdu, he judged that the Thunderbolt army was very likely to go down the river from Guankou Village, so he left his henchmen to guard Genting City and notified the surrounding forts to prepare for support, while he went to Jintang City to take command. This is also the reason why after Genting City was captured by the Thunderbolt Army, Jiagu Dragon Ancient was able to quickly gather the new annex army of the surrounding fortresses.

Yao De naturally knew the attitude of the Thunderbolt Army towards traitors, and his act of killing his uncle Yao Shi'an to sacrifice the city was even more intolerable to the Southern Song court, which respected science. For him, since he became a lackey of the Mongols, there was only one way to go to the dark. In order to prevent deserters, he implemented the squad sitting system, that is, if there are deserters in the squad, the whole squad will become cannon fodder at the front, and if there are deserters again, the team will be killed, and if there are deserters for the third time, the system of random killing will be implemented, that is, one person out of ten people will be randomly selected to be killed, so that the soldiers will supervise each other in this form of terror and sitting. Not only that, but he also organized a team of overseers, and he was unsuccessful in killing those who dared to retreat. Of course, Yao De did not blindly use tough methods, but used carrots and sticks, and the cake of promotion and fortune was indispensable, and he even did not hesitate to take out the concubine as a hanging red.

Under coercion and temptation, although Jintang only had 500 new annexes, it burst out with amazing combat effectiveness, and it was the thousands of people of the Thunderbolt Army who were forcibly blocked. After learning about these situations from the deserters, Huang Dagen adopted the means of political offensive as the mainstay, supplemented by military strikes. He first sent people to shout in unison outside the city, claiming that only Yao De and his henchmen would be punished, and the rest would surrender without killing. At the same time, musketeers were used to snipe the new annexes that appeared on the city walls, focusing on the elimination of officers and overseers. Each squad of the special brigade has a precision musket shooter, who can shoot accurately at about 100 meters, although the hit rate is only about 50%, but it also suppresses the activities of the Jintang defenders. However, although this method is effective, it is difficult to win the city in a hurry.

The military situation is like fire and water, and as the appointed time approaches, Huang Dagen's heart is becoming more and more anxious. Just when he decided not to care about casualties and was about to launch a siege on all sides, he saw the north gate of Jintang open wide, and a group of new annexes rushed to the Thunderbolt position, shouting "We have surrendered", while the new annexes on the city wall behind them desperately dropped arrows to try to stop the deserters. Just as the defenders of Jintang were about to close the city gate, more than a dozen Thunderbolt cavalry rushed straight towards the city gate. Everyone looked at it intently, and this was the teaching brigade commander Zeng Yong and his subordinate officers. Since the establishment of the cavalry unit, the Perak Army has gradually equipped the infantry with horses for communication and reconnaissance purposes, and has also equipped the commanders above the battalion level with mounts. Now it is all the officers above the brigade level who are rushing to the gate of Jintang.

Just when the new annex army opened the city gate, Zeng Yong, who was commanding the battlefield at the north gate, found something strange from the telescope: first there was chaos at the city gate tower, and the defenders were fighting each other, then the drawbridge on the moat was lowered, and then the heavy city gate was slowly pushed open, of course he would not let go of this kind of fighter. It was only because of the suddenness of the incident that he had to come and call the officers around him to charge with him. The soldiers of the teaching brigade saw the gate of Jintang open, and saw the brigade commander and other commanders charging on horseback, and although they did not know what was happening, they also grabbed their weapons and rushed towards the gate. Since the Jintang garrison did not have heavy trebuchets and eight-ox bed crossbows, and the range of their light trebuchets was less than 200 meters, the fence of the teaching brigade was already half a mile outside the city. The distance of half a mile was only a matter of a moment for the cavalry. When the city gate was halfway closed, Zeng Yong had already rushed to the suspension bridge that had not yet been pulled up.

There are not many new attached troops in Jintang County, and after deducting the supervising team and Yao De's personal soldiers, there are only more than 100 people on each city wall, and even if you add the people who are forcibly conscripted on the wall, there are only about 300 people. The new annexed army at the north gate was originally only 100 people, killed more than 10 people by killing each other, and escaped from the city of more than 60 people, so there were only more than 30 soldiers left, and there were only more than 10 soldiers guarding the city gate. As for those people, after the internal strife in the new annexed army, they took the opportunity to disperse in a hurry. More than a dozen new soldiers guarding the city gate saw Zeng Yong and others riding their horses and killing them, so they had to give up the half-closed city gate and retreated. By the time Yao De arrived with his people, Zeng Yong and other officers had already pushed the city gate open, and behind them were a steady stream of soldiers from the Teaching Brigade.

Although Yao De's personal soldiers and the Overseers were all brave outlaws, they were the opponents of the soldiers of the Teaching Brigade. At the forefront were the Miao Jiang soldiers led by Yang Bangxian, who opened the way with grenades, and a wave of charge disrupted the formation of the new annexed army and drove them to the county government in the center of the city. Yao De and his henchmen knew that surrender would not have good fruit to eat, so they naturally resisted stubbornly. They blocked the gate of the county government and shot at the Thunderbolt soldiers who jumped over the wall, causing the soldiers of the teaching brigade to suffer a great loss, killing and wounding several people. Yang Bangxian was furious, ordered people to blow up the wall of the county government courtyard with gunpowder, threw dozens of grenades, and then released several rounds of muskets, and only after the smoke of gunpowder cleared up did he lead people to carefully walk into the county office. I saw that there were corpses lying all over the place, one of which was powerful and wearing iron armor. Immediately, the captives were called over to identify that the deceased was Yao De.

Killing Yao De and taking Jintang City does not mean that the army can go down the river, because the channel has been blocked by sunken ships. Fortunately, the channel was not completely blocked, barely enough to accommodate the passage of the dinghy. Huang Dagen had no choice but to send people to dredge the channel as soon as possible, and on the other hand, he asked the commander of the first battalion of the special brigade, Dunzhu, to lead some soldiers to Genting City in a small boat. Most of the boats Huang Dagen brought on this trip were transport ships, and only about 20 light boats could be towed from the shore of the blockage. Dunzhu and the others took these boats to support their comrades in Genting City. The battalion under his command originally had 500 people, which was the strongest battalion in the special brigade, and 300 people had been taken away by Dong Hu to go to Genting City, and now the 200 people he led were all the remaining strength of the first battalion.

Jintang City is only about 60 miles away from Genting City, because the boat goes down the river and orders people to take turns paddling, so the boat is extremely fast. When they were halfway through, they met the soldiers sent by Dong Hu to ask for help, and everyone saw that they were covered with scars and smoke, dust and bloodstains on their faces, and they heard that the brothers guarding Genting City were in critical condition, so they couldn't help but cry and speed up their rowing, and for a time there was a situation of hundreds of boats competing for the current. Of course, Dunzhu understood that his subordinates were eager to rescue, but he also understood the truth that "if you want to hurry, you can't reach it", so he ordered to slow down a little, on the one hand, to prevent excessive physical loss, and on the other hand, to be cautious and cautious, to prevent being ambushed by the Mongolian army.
