In the blink of an eye, the autumn harvest season has arrived, and the mountains and forests are still green. The plains were golden, to be precise, under the Thunderbolts, and the golden yellow came from the rice that was about to be harvested. On the other hand, the area occupied by the Mongolian army in western Sichuan is also yellow, but it is mostly yellow weeds. In the grain fields that are not contiguous, soybeans account for the majority, and the proportion of rice is not high, so the bright golden yellow color is missing. Although soybeans are nutritious and drought-tolerant, their yields are much lower than those of rice. As for why rice with high yields is not grown in the areas occupied by the Mongolian army, it is because rice requires higher irrigation and cultivation. Liu Heima, who was in charge of western Sichuan, was not a Mongol general who only knew how to plunder, but he was not interested in the slow construction of water conservancy. Without water irrigation, the few rice yields of the Mongolian army can be imagined.

There are more than 10 million acres of fertile land in the western Sichuan Plain, of which the Mongolian army occupies more than two-thirds, and the Perak army only occupies 3 million mu, less than one-third. Thanks to intensive farming and cobweb-dense irrigation ditches, as well as man-made flooding and nutrient-rich silt, the Perak Army will have a bumper crop of grain this autumn. When the Mongolian troops on the other side of the Jinma River saw this, they were naturally greedy, and they couldn't help but think about grabbing food. It's just that after the Battle of Pengshanshui, the Mongolian army has been disabled, and there are not even enough boats to cross the river, how can they cross the river? I had to try to break through from Guan Kou Village.

As long as the Mongolian army takes Guankou Village, it can not only open up the Weimao Road, but also detour to Yongkang City from the mountain trail behind the village. It's just that Guan Kou Village has been upgraded to a cement fortress, and heavy fortress guns have been added. In addition, Shi Zhongshu, who was responsible for guarding Guankou Village, was extremely cautious, and several sneak attacks by the Mongolian army were blown up by artillery and mines without even getting close to the wall. After Yu Zhu became the person in charge of the Liuqiu Company, Zeng Yong, the commander of the garrison brigade teaching battalion, was promoted to brigade commander and still served as the commander of the teaching battalion. Shi Zhongshu is the deputy brigade commander and still the commander of the guard battalion. When the military and political council discussed the candidates, they took a fancy to Shi Zhongshu's calm style and entrusted him with the important task of Guan Kou Village.

The Mongolian army tried the defense line of the Perak army several times and suffered heavy casualties. It's just that the Mongolian army is predatory, and when they see the grain everywhere in the fields, they can hold back the heart of robbery. Liu Heima knew that there was no gap to take advantage of, so he adjusted the direction of the raid. Even if the Thunderbolt army is not easy to deal with, then go to the direction of Jiading, although the grain output there is not as good as that of western Sichuan, but it is better than the vast area. And unlike the repeated defeats to the Thunderbolt army, the Mongolian army had a huge psychological advantage over the Jiading army, after all, the Jiading army had never won a field battle with the Mongolian army.

Liu Heima wanted to grab grain in Jiading, but he didn't know that Yu Xing also wanted to go north to grab grain. After the Battle of Diaoyucheng, the Mongol army retreated to the north. At this time, although there were many Mongolian troops stationed in Sichuan, most of them were new annexed troops with weak combat power, and the strength of their own tribe was even less than that before Meng Ge entered Sichuan. Yu Xing is currently digging into the camp in order to succeed Lu Wende's Sichuan system envoy, and needs a big victory to add chips to himself. His target was Longzhou, which had been captured by the Mongol army in the last Battle of Jiading, and Jingyan County. These two places are not far from Jiading, especially Jingyan County is only 100 miles away from Jiading Fucheng, and there are waterways to communicate, which has become Yu Xing's goal.

Because the Thunderbolt army of Pengshan City firmly choked the waterway for the Chengdu Mongolian army to move south to Jiading, Yu Xing, who had no worries, led 3,000 elites to attack Jingyan along the waterway. The Mongol army guarding Jingyan had 200 cavalry and 1,500 new annexed troops, and they were quickly crushed under the attack of the Jiading army by land and water. The 200 Mongol cavalry fled unscathed, while most of the new annexes fled in all directions, and the rest were taken prisoner. Yu Xingzhi, who was easy to succeed, was satisfied, so he sent 1,000 men to continue the pursuit in the direction of Longzhou, and he himself marched into Longzhou after clearing the Jingyan conspiracy.

The so-called purging of spies is just a means for Yu Xing to loot wealth. Jingyan is as rich in well salt as Qiongzhou, and it has always been an important place for finance and taxation, and there are naturally many wealthy households in the county. Yu Xing's standard for spies was whether they paid a certain amount of salt tax to the Mongols, and if according to his standards, the vast majority of salt merchants in Jingyan County were spies. Of course, spies do not have to behead or confiscate family property, but only need to hand over the "money of atonement" to get away with it. Naturally, most of this silver would fall into the pockets of Yu Xing and his minions, which was why he was not in a hurry to go to Longzhou.

Just when Yu Xing was enthusiastically torturing the "Mongol army spies", news of defeat came from the front - the 1,000 Jiading army pursuing had been defeated. Hearing the news, he was taken aback, and immediately scolded bitterly, a thousand elites would actually be defeated by defeated soldiers? As the defeated soldiers fled back one after another, the situation gradually became clear. It turned out that the defeat of the 1,000 Jiading army was not unjust, because they encountered 2,000 Mongolian cavalry. In the field battle, it is obviously impossible to fight against 2,000 cavalry with a thousand infantry army, and it is not possible to say that the Jiading army is not good, even the Thunderbolt army field brigade led by Cao Ergou is not good.

Liu Heima, and Yu Xing both tried to take advantage of the autumn harvest to sneak attack and grab food, but found that the other party had the same idea. In Yu Xing's opinion, the Mongolian army should go to grab the food of the Perak army, which is closer. Moreover, just a few days ago, the Perak army sent a large number of elites to Ezhou, and when the fleet passed through Jiading, Yu Xing ordered people to count them, and there were more than 200 large and small ships, and the personnel were said to be nearly 2,000 people, and the military strength had been weakened a lot. Moreover, Jiading's spies also learned that the Mongolian army has frequently attacked the defense line of the Perak army recently, and is gathering troops, and it seems that there will be a big move. Only then did he make up his mind to take the opportunity to send troops.

In Liu Heima's opinion, this Yu Xing was really bold, not only took the initiative to attack, but actually dared to attack Longzhou with only a thousand people. Fortunately, he was already ready to go south, otherwise he might have been able to get his hands on it. At that moment, he sent cavalry to reinforce Longzhou. Under the onslaught of the Mongol cavalry, the Jiading army, which had pursued to Longzhou, was crushed at the touch of a button. Fortunately, there are also many hills and low mountains around Longzhou City, and many Jiading troops fled to the mountains and luckily picked up a life. But these 1,000 people were still heavily wounded under the pursuit of the Mongol cavalry, and only more than 600 people fled back to Jingyan.

The Mongol cavalry chased all the way to the city of Jingyan, but they could not attack the city without siege equipment, so they had to wait for the arrival of the new annexed army. Although Yu Xing's character is inferior, he is a fierce general, so he naturally refuses to retreat easily. At present, the Jiading army is defending the city, and there is a naval army to help, and the grain route is unblocked, so they are not afraid of the Mongolian army at all. In Yu Xing's view, this well research is an important place for finance and taxation, and it is definitely not easy to give up. If you can't beat it, you can also return to Jiading by water. More crucially, the "money for indulgence" has not yet been scavenged. It is said that in just a few days, he has gained thousands of taels of silver, and his cronies have also made a lot of money, and they are willing to retreat easily.

After the arrival of the new annexed army, the Mongol army began to build siege equipment. And Yu Xing was not idle, he first sent people back to Jiading to transport siege equipment, and then sent people to Chongqing Mansion, on the one hand, he asked Ouyang Xuan to send troops to attack the Mongolian army in order to contain the Mongolian army, and on the other hand, the lion opened his mouth and asked the Thunderbolt army to provide artillery, muskets, grenades, and mines....... After Ouyang Xuan received the letter, he sent special forces to attack the Mongol army in small teams and use guerrilla warfare to attack the Mongol army in all directions, and the warships shelled the Mongol targets along the river to remind the Mongols of the advantages of the Perak army. As for Yu Xing's request for firearms, he sent 500 old-fashioned grenades to deal with the matter.

The offensive and defensive sides did not have many troops, but they were all elites, and they couldn't help each other for a while. The Mongol army was 2,000 cavalry plus 3,000 new annexes, while the Jiading army was 4,000 men—Yu Xing transferred 1,500 men from Jiading. Because both sides were determined to win Jingyan, and the autumn grain had just been harvested and had the foundation for a protracted war, the battle situation was stalemate.
