After the fleet departed from Chongqing, although it was down the river, it only arrived at Jiading, 300 miles away, three days later. On the one hand, the trip was not a military operation, and there was no hurry; On the other hand, transports made up the majority of the fleet, and these heavy-duty ships were certainly not as fast as the warships, so they had to stop and go. In the case of the convoy, several reconnaissance ships led the special company ships to clear the way ahead. The ships of Ouyang Xuan and the others followed, and in the middle were the ships transporting arms and the warships of the naval company. At the back were Banshu's merchant ships, which were also guarded and were not afraid of attacks by small bandits.

Ouyang Xuan did not order the fleet to dock in Jiading. During this time, Yu Xingzheng led his troops to confront the Mongolian army in Jingyan, and it was his son Yu Dazhong who stayed in Jiading. If Yu Xing was in Jiading Mansion, as a nominal subordinate, Ouyang Xuan would hate his face no matter how much he hated it, and he would have to endure the churning in his stomach and deal with him. This Yu Dazhong was stupid and greedy, Ouyang Xuan didn't bother to pay attention to him, and he didn't want to entangle with him, so he sent someone ashore to inform Jiading Mansion, bought some fresh water, and continued to go down the river.

Just a few days ago, Yu Xing sent people to Chongqing Mansion to ask for firearms, and asked Ouyang Xuan to send troops to reinforce or attack Chengdu to contain the Mongolian army. During the Jingyan offensive and defensive battle, the Jiading army used trebuchets to fire grenades, causing serious losses to the siege equipment of the Mongolian army. It's just that Yu Xing doesn't know how to save things at all, and in two or three days, he smashed all the 500 old-fashioned grenades sent by the Thunderbolt Army. When the Thunderbolts ran out, Yu Xing ordered the use of imitation grenades. It's just that the grenade imitated by Jiading craftsmen not only lacks the power of the explosion, but even the burning time of the lead is not easy to control. Although these inferior products also destroyed a lot of siege equipment of the Mongolian army, they also destroyed several existing equipment due to the explosion in advance.

Seeing that he couldn't attack for a long time, Liu Heima reinforced 20 artillery pieces to the Jingyan Mongolian army, which he finally forged by smashing pots and selling iron. The previously cast artillery was either captured by the Thunderbolts and re-smelted into iron, or sunk into the water as the ship was destroyed. Although these artillery pieces had a short range, small power, and poor accuracy, they also frightened Yu Xing a lot, and he also ordered more than ten artillery pieces to be transported from Jiading to shoot at the Mongolian army. For a time, the sound of cannons under the head of Jingyan City rumbled, the fires flashed, and the choking smoke was filled.

After several days of shelling each other, both sides found that the enemy was still alive and kicking, and the artillery, which had cost a lot of money, was not very lethal. In particular, the Mongol army was dismayed to find that seven of the 20 guns had lost due to the bombing, and the number of people who had died in the bombing was not much less than that of the Song army who died in the shelling. It's just that what they don't know is that the Song army defending the city also had two doors blown up. It is said that although the artillery imitated by the Jiading army is unbearable, after all, it has been instructed by the Thunderbolt army, and its performance is much higher than that of the Mongolian army. Therefore, the war situation is still in a stalemate.

Ouyang Xuan rejected Yu Xing's request this time. In fact, if the Thunderbolt Army had enough ammunition, Ouyang Xuan would still send someone to send some grenades. However, during this period of time, Yu Zhu took a large amount of ammunition with him, and he had to transport ammunition to Banju, and he also had to ensure the ammunition needs of the caravan guards, so the ammunition of the Thunderbolt Army brigades was seriously insufficient. Ouyang Xuan had no choice but to order to give priority to ensuring the needs of the naval army and the defenders of Guankou Village and Baizhang City. Now the Thunderbolts only have enough ammunition to fight a medium-sized battle.

As for Yu Xing's request to send troops, Ouyang Xuan refused without hesitation. At present, the Perak army has more than enough to defend and not enough to attack, and it is simply unable to attack Chengdu. As for sending troops to Jingyan, it is even more impossible. According to Yu Xing's urine nature, he will definitely use the Thunderbolt soldiers as cannon fodder and consumables. Of course, Ouyang Xuan's reason for replying to Yu Xing's envoy was high-sounding: "The elite of our army went to Ezhou according to the order of Lord Silu in Sichuan, and the current defense is already difficult, and there are really no soldiers to send."

When the fleet arrived in Xuzhou, Ouyang Xuan had dysentery. It was autumn when there was a high incidence of food poisoning, and because of the raging war, most of the towns along the route withered, and it was difficult to replenish fresh food. Ouyang Xuan has always insisted on eating and living with the military and civilians, and there is no special treatment, so this time he and Lu Dezhi also fell for it. He wanted to go ashore to visit the Xuzhou government, but his stomach was so troubled that he had to send Zhu Zhuozi and Dong Hu, who were in good health, to visit him.

Ouyang Xuan was young and strong, and he had been refining all year round, so when the ship arrived in Luzhou, he had fully recovered, and Lu Dezhi's condition had also improved greatly, and his face was a lot ruddy, but his body was still weak. When the ship arrived at Shenjian City, Ouyang Xuan took Dong Hu to visit the official mansion in the city. When the two arrived in the city, they were not met by Zhu Zhensun, the deputy envoy of Tongchuan Road and the prefect of Luzhou, but Liu Zhen. Zhu Yusun had already led his army to Ezhou with Lu Wende.

For Liu Zhen, Ouyang Xuan's mood is extremely complicated, and in the history books, Liu Zhen is like a boat drifting with the tide, and he repeatedly rebelled in the tide of the current situation. On the one hand, this person is brave and strategic, and has followed Meng Heng and Li Zengbo to make countless meritorious contributions, bravely crowning the three armies, known as "Saicun Filial Piety". On the other hand, he was also very utilitarian, and after being framed by Lü Wende and Yu Xing, he surrendered to the Mongols, causing a great deal of deterioration in Sichuan. Later, he proposed to Kublai Khan the key strategy of "if you want to destroy the Southern Song Dynasty, take Xiangyang first", and it is not an exaggeration to say that he is one of the culprits in the destruction of the Song Dynasty. Thinking of what was written in the history books, Ouyang Xuan was inevitably a little depressed.

Ouyang Xuan had a long talk with Liu Zhen, and said his heartfelt words of determination to resist Mongolia to the end, on the one hand, he was testing whether Liu Zhen's determination to resist Mongolia was firm, and on the other hand, he told Liu Zhen that he, Ouyang Xuan, would fight to the end without compromise against those who surrendered to Mongolia. Before leaving Shenjian City, he ordered someone to give Liu Zhen a lot of money, silk, gold and silver, and even gave Liu Zhen the saber on his waist, but he did not give him some firearms. Because he really didn't know if his contact with Liu Zhen would change the original historical trend and make Liu Zhen no longer surrender to the Mongolian army. Although with the accumulation of Mongolian technology, it was extremely difficult to imitate high-performance firearms. However, technological expansion is inevitable, and what the Perak Army has to do is to slow down the pace of imitation by the Mongolian army as much as possible, and naturally it cannot hand over firearms to people with two hearts.

Liu Zhen sent Ouyang Xuan to the dock. On the one hand, he admired Ouyang Xuan for starting from scratch and creating a world surrounded by wolves. As for Ouyang Xuan's patriotism and compassion for the people, he didn't care; On the other hand, because of the heavy gifts given by the Thunderbolt Army, not to mention the money, gold and silver, only the saber given by Ouyang Xuan was worth a lot of money. This knife is made of chromium-containing refined iron in Dayi Mountain, which is repeatedly forged by cold forging process, which is not only sharp and abnormally sharp, but also does not rust, which is a rare treasure knife. Liu Zhen, as a perennial man who handles swords, naturally can't put it down.

At the same time that Ouyang Xuan was communicating with Liu Zhen, Dong Hu also went to visit Xu Tuiguan in the city. Dong Hu didn't know why Ouyang Xuan asked him to make a special trip to visit this official, but he carried it out to the letter. It's just that Xu Tuiguan did not accept the property of the Thunderbolt Army, but returned in full. This made Dong Hu think about it, such an official who does not love money is really rare in the officialdom of the Southern Song Dynasty, and he is simply an outlier, which may be the reason why Ouyang Xuan intends to befriend him.
