The fleet continued down the river and arrived in Luzhou two days later. There were still many bandits on this stretch of the road, but these bandits were far more rampant than the bandits who did not have Xuzhou, and they only sent boats to follow them from a distance, and fled after the tentative attack failed. At this time, the Luzhou Governance Office has been moved to the Shenjian City on the Shenjian Mountain by the river, and Zhizhou is the grandson of Zhu Xu, a famous minister of the Anti-Mongolian Dynasty. He was a native of Langzhou, Sichuan, who survived the massacre of the Mongol army in Chengdu in his early years, and was a staunch anti-Mongol faction in the imperial court. Ouyang Xuan wanted to go ashore to visit him, but unexpectedly, he was closed again. Like Xuzhou City, Shenjian City also fires arrows at fleets that want to dock, and does not respond to flags and shouts. Ouyang Xuan was not reconciled, ordered the fleet to stop and wait outside the fire range of the city wall, and ordered someone to take a small boat to negotiate. Li Kaipeng, who only went to negotiate, was not allowed to enter the city, but only had a conversation with a small school in Shenjian City outside the city gate and then returned in a huff.

Li Kaipeng returned to Ouyang Xuan, and the reason why Zhu Yusun did not open the door was because "once he was bitten by a snake, and he was afraid of grass ropes for three years". It turned out that after Niu Lin defeated Zhang Shi, a Song army general named Zhang Wei led a fleet to Shenjian City, claiming to be here to assist in the defense. This Zhang Wei is a little famous in the Sichuan Water Army, and many people know about the Water Army of Shenjian City. Just when the defenders were about to open the city gate to welcome him into the city, unexpectedly, a guard next to Zhang Wei suddenly rushed out, running to the city gate and shouting, "Zhang Wei has surrendered to the tartar", although the guard was immediately shot by Zhang Wei, but the vigilant defenders have closed the city gate again. It turned out that this Zhang Wei surrendered to the Mongols after the defeat of Pu Ze's army in Chengdu, and this time he was appointed as a vanguard officer by Niu Xuan to open the city gate, and not far behind him was the Mongol army led by the Mongol army Qianhu Dark Dura.

To say that the terrain of this Divine Arm City is dangerous, it is not under Genting City, as long as there is no food to force it in, it is absolutely impossible. Therefore, after the New Nian army came, it only destroyed the water army in Luzhou, but it had no choice but to continue to go in the direction of Chongqing Mansion. With Zhang Wei's experience, Shenjian City naturally refused to open the door. What's more, although Zhu Yusun knew that there was a Yongkang County in Chongqing Prefecture, but when he got the news that the Western Sichuan Plain had all fallen into the hands of the Mongols, did Ouyang Xuan, who claimed to be the commander of Yongkang County, surrender to Mongolia? Where did this Thunderbolt come from? With these questions in his heart, where would he open the city gate?

Ouyang Xuan listened to the reason, shook his head with a wry smile, and had to order the fleet to continue to march in the direction of Chongqing Mansion. When Li Kaipeng was in Shenjian City, he heard the little colonel say that the Mongolian navy often came and went on the water, so he suggested preparing in advance. Huang Dagen, who had just suffered a big loss from the water bandits, naturally did not dare to slack off, and ordered someone to drive a small boat in front of the fleet. When the water bandits were defeated on the Xuzhou River, the Perak army was scuttled by a frigate boat, and several boat boats were also captured. This kind of small boat was originally used by fishermen for fishing, but it is flexible and light, and it can run fast on the river, which is suitable for reconnaissance. In less than half a day, the reconnaissance ship captured a Mongol ship and captured alive several Mongol sailors—to be precise, new annexes who had surrendered to the Mongols.

The reconnaissance boat captured from the bandits was originally a fishing boat, and when it met two Mongolian naval vessels that were going up the water, it was naturally regarded as a thing in the pocket by the predatory Mongolian army. In the eyes of the Mongolian sailors, this fishing boat looked like a soft pestle, so they relied on the boat to meet them. At first, the reconnaissance personnel of the Perak Army saw that there was nothing special about the incoming ship, and the sailors on the ship were also full of Chinese, and thought that they were the Song army's navy, but when they got closer, they were surprised to realize that it was the Mongolian navy, so they immediately exchanged glances, and suddenly attacked the nearest ship when they were on the side. Most of the traitors on this ship were wiped out by muskets and grenades in a hurry, and the rest were captured in confusion. The other ship saw that the situation was not good, and fled.

After interrogating the prisoners, it was revealed that they were subordinates of the subordinate general Zhang Wei, who were ordered to reconnoiter along the river near the city of Chongqing. Niu Ling came from along the river, defeated the Xuzhou naval army to suppress the Luzhou Shenjian City, and broke through the layers of Pu Zezhi's defenses, the prestige was extremely loud, but there was no way to take the strong city defense of Chongqing Fucheng. He had no choice but to go to Fuzhou and prepare to fortify the section of the river at a dangerous point to prevent the Song army from reinforcing Sichuan from the Jinghu battlefield. This Niu Ling was extremely cunning, and before going to Fuzhou, he used his usual trick to deliberately lead the Chongqing Prefecture Navy to follow and pursue, but he secretly ambushed heavy troops. The pursuing Chongqing Prefecture naval army was defeated under the combined attack of the Mongolian naval army and the shore infantry army.

After this fiasco, Pu Xue, who had already been beaten out of the psychological shadow, was ordered to hold on to the water village, and the naval ships were also strictly ordered to stick to the water village. Since then, Mongolian ships have been able to move freely on this section of the water. Ouyang Xuan listened to the prisoner's confession and decided not to go to Chongqing Fucheng again. On the one hand, the Chongqing government, which had suffered successive defeats, was definitely heavily guarded and would not let their fleet of unknown origins enter the city, and on the other hand, Ouyang Xuan was only a small county commander under the Southern Song Dynasty bureaucracy, and there was a high probability that he would not receive him when he entered the city.

Sure enough, before the fleet approached the city of Chongqing, the defenders at the head of the city ignored the Song flag hanging on the bow of the ship, shot a large number of arrows, and fell far in front of the Thunderbolt fleet, splashing a large splash. Of course, it is no wonder that the defenders of Chongqing Prefecture, after all, the Song army descended like a tide of troops and generals in the front of the Mongolian army, and it was really difficult to distinguish between the enemy and me, and this fleet of unknown origin did not make a code word, who knows if they are their own people? With the experience of Xuzhou City and Shenjian City, the Thunderbolt Army fleet did not bother to talk about it again, but went straight to the Diaoyu City of Hezhou Zhishu.

It is 140 miles from Chongqing to Diaoyu City by water, and it takes two days to reach it because it is going upstream. Since the Perak Army fleet departed from Chongqing Province, there were ships following behind. Huang Dagen only regarded it as a reconnaissance ship of the Song army, but he didn't care about it. It's just that there are more and more ships trailing, from one or two to more than a dozen. When Huang Dagen was about to send a ship to drive him away, Ouyang Xuan stopped him, and he also saw that it was a ship of the Mongolian navy. The Mongolian ships were apparently waiting for reinforcements to arrive. For these Mongolian ships that could not be followed, Ouyang Xuan instead ordered the fleet to slow down. This strange order made Huang Dagen puzzled. Facing the suspicious crowd, Ouyang Xuan explained with a smile: "We want to enter the three cities of Xuzhou, Luzhou, and Chongqing but can't, but we suspect that we are the Mongolian army, and Hezhou will not open the city gate under such circumstances." For now, the only way to do this is to use the heads of these Mongolian soldiers to open the gates of Hezhou."

The Perak fleet sailed in front unhurriedly, and the Mongolian fleet behind followed unhurriedly and far away. The number of Mongolian ships is increasing, and when there are still 40 miles away from Diaoyu City, there are more than 20 ships following behind. When there were still about thirty miles away from Diaoyu City, a number of light boats appeared upstream one after another, which were the reconnaissance ships of the Diaoyu City Naval Army. At this time, the Mongolian fleet began to change formation, and Huang Dagen knew that this was the Mongolian army preparing to move. Although the Song navy from Xuzhou to Fuzhou was suppressed, the Hezhou navy, which was located on a tributary of the river, did not suffer much loss and still retained a large number of ships. More importantly, the main force of the Mongolian army is on the line from Chongqing to Fuzhou at the moment, and the force near Hezhou is not strong. If you don't do it at this time, there will be no chance for the Diaoyu City Navy to be dispatched.
