The two backbone companies of the Perak garrison led by Yu Zhu led by Zhu Zhu'er were the two backbone companies of the Perak Army garrison led by Zhu Zhu'er, who had been ambushed here yesterday.

Two days ago, Dong Hu received the news that the Mongolian army was trying to march from Heming Mountain to Liuliba. Dong Hu was originally born in Orion, so he naturally knew that Jiguan Mountain seemed to be closed, but there were many hidden trails leading to Heming Mountain, Qingcheng Mountain, and even Wei and Mao Prefectures in the Fan District.

These hidden trails, though unwell-known and treacherous, make it impossible to pass through the army under normal conditions.

But he also knew that if a guide led the way and was well prepared, as long as he was not afraid of casualties, he could still pass through a small army.

In fact, he also acted as a guide, taking Ouyang Xuan and others from Liuliba to the outside of the mountain through the hidden path, and successfully bought back salt from the fire well.

After the Perak army occupied Wanjiaping, Xiong Ben also tried to sneak attack Wanjiaping from the mountain path in the direction of Yongkang City.

After Linde's rebellion, in order to ensure that the mountain is no longer threatened from within and from behind, he and Yu Zhu have made a lot of remedial measures.

Yu Zhu mainly strengthened the equipment training and rapid reaction capability of the three backbone companies of the garrison battalion, and set up sentry posts and secret sentry posts in important sections of the mountain.

What Dong Hu did was to arrange a large number of eyeliner, and there were enthusiastic people in all villages, factories and mines in the mountains to serve as part-time intelligence officers, and regular training was conducted, and those with outstanding results would also be rewarded.

These people were called by Ouyang Xuan

"Chaoyang masses", and called Dong Hu's practice

"People's War". In these

Among the "Chaoyang masses", Dong Hu values the two groups of hunters and medicine pickers the most. Unlike ordinary mountain people, who only cut trees and collect wild vegetables nearby, herb pickers often have to travel far distances to collect precious medicinal herbs, while hunters hunt farther away in order to track down the herd.

Especially in recent times, a large number of refugees have poured into the Jiguan Mountain, which has greatly squeezed the living space of birds and beasts.

Due to the food rationing system, these refugees have begged for food in the mountains and forests, and also hunted a large number of prey, which greatly reduced the prey in the Jiguan Mountain area.

Hunters had to hunt in Qingcheng Mountain, Heming Mountain, and even in the neighboring Tibetan region, and although many refugees poured into these mountains, the number of them was much smaller than that of those who fled to the Jiguan Mountain.

The Mongolian army led by Zhu Zhu'er was discovered by these hunters and quickly reported to the internal guard battalion. It was these hunters who told Yu Zhu that the Mongol army must pass through this stream to replenish water, and only need to wait here and set up an ambush.

In fact, these Mongolian troops were found to blame Zhu Zhu'er, it was his bandits who knocked the bones and sucked the marrow in the Heming Mountain, causing the people to have no intention of giving birth, and only a small number of refugees came, which caused the number of prey in Heming Mountain to still be considerable, attracting the hunters in the Jiguan Mountain to hunt.

Of the more than 260 people led by Zhu Zhu'er, except for only a dozen extremely athletic people who escaped, the rest were killed and captured, and he was also injured in the thigh by a grenade, so he couldn't escape at all.

To say that this Zhu Zhu'er is also tough, he knows that the Thunderbolt Army hates traitors the most, and he knows that he will definitely not end well if he is captured, so he simply wiped his neck with a knife.

After clearing the battlefield, Yu Zhu left three days of food and water for the seriously injured prisoners and those who would lose their labor even if they were healed, and then escorted 140 prisoners on the return journey back to Liuliba.

It was not to blame that Yu Zhu was hard-hearted, and the Perak soldiers had a hard time climbing over this steep mountain, and they were not willing to risk rolling off the cliff to carry the enemy's wounded soldiers.

Besides, the resources of the Thunderbolt Army are now tight, and it is very difficult to keep the fleeing refugees from starving, where can they take care of these injured Tartars and traitors.

The secret one was naturally very angry when he got the news of the failure of the sneak attack. It's just that Zhu Zhu'er is dead, so he has to turn his anger on Jiagu Long Gugu, and the reason for the punishment is that the tunnel is excavated slowly.

In fact, Jiagu Dragon was already working very hard in ancient times, and in order to speed up the progress, he even introduced the last elimination system.

Ten tunnels that are working at the same time are ranked every day, and the slowest digging will be whipped, and the number of whips that will be doubled for two consecutive days, and those who are ranked last for three consecutive days will lose their heads.

In the ten days since the excavation, four whips have been broken. It's just that no matter how much you whip it, the progress of the tunnel is still slow, and the fastest progress is just digging into the middle of the moat in front of the city wall.

There is no other reason, the main reason is that the tunnel has to pass through the trench in front of Yokohara Fort, and the difficulty is too great. According to the plan, there should have been a moat of 20 meters wide and 15 meters wide in front of Yokohara Fort, but due to the difficulty of excavation, the depth and width of the excavation did not meet the requirements, and it was impossible to divert water into a river, so the moat became a moat.

Although the trench had been almost filled, the Mongolian army still had to pass under the trench due to the mixture of earth, stone and wood.

It was already difficult to dig tunnels, and the Mongolian army had to dig up the gravel layer that the Thunderbolt army could not gnaw, which was even more difficult.

You must know that the quality of the iron tools of the Thunderbolt Army is not even a star and a half higher than that of the Mongolian Army. These are not the only things that make the secret man angry.

Liu Heima, from Chengdu, sent people to say that because he had been robbed of a lot of food by the Thunderbolt army, the food was already in short supply, and he had halved the food of the new annexed army that had no combat mission.

In more than a month, it will be the autumn harvest season, and it is necessary for the people and even the new attached army to harvest and collect grain, otherwise not only will there be no grain to be transported to the New Dollar Department, but even the garrison in western Sichuan will be short of grain.

In the eyes of the secret fire, Liu Heima was urging the war, tactfully suggesting that the war was slow. Although the secret Huoli is a pure Mongol, deeply trusted by the Great Khan of Mengke, and also appointed as the military officer of Western Sichuan, Liu Heima is also a confidant of the Great Khan, which can be seen from the fact that although he is a Khitan, he was entrusted with the political affairs of Western Sichuan.

Liu Heima was not allowed to join him, and told Meng Ge Khan that he had no way to command the fighter plane. In addition, due to the hot and humid weather, the number of sick soldiers in the Mongolian military camp is also increasing.

The new annexed army and the people were fine, but the Mongol cavalry and the Mongol Han army were not adapted to the water and soil, and the number of sick people reached one-fifth, and more than 100 horses died.

Bad news also came from Chongqing Fucheng and Sandushui, saying that the small boats of the Perak Army frequently approached to reconnoitre, and it seemed that they had the intention of attacking.

The pontoon bridge of Sandu Water is not only a grain route, but also a land passage to Chengdu, and Chongqing Fucheng is the key to preventing the Perak army from reinforcing Hengyuan Fort.

If the water passage in these two places is opened, it will definitely not be good news for the Mongolian army in Yokohara Fort.

Three days later, the continuous heavy rain made the secret fire even worse - the tunnels that were about to be excavated under the walls of Yokohara Fort were completely destroyed.

In fact, the rain did not fall without warning, just a few days ago the sky gradually became gloomy, although the sun came out from time to time, but it was no longer as hot as the previous days, but the temperature was more muggy.

The generals of the new annexed army stationed in western Sichuan all the year round naturally knew that every summer was the time when the rainfall in western Sichuan was concentrated.

However, since the attack on Yokohara Fort, there has not been heavy rain in western Sichuan. It's the end of July now, and judging by the experience of previous years, this unusual weather is a precursor to heavy rain.

Hearing the advice of his men, the Secret Commander ordered the drainage ditches around the camp to be deepened, the grain and grass to be transported to higher places, and even built a new shelter for the horses on the side of the mountain, but he refused to stop digging the tunnels, and only ordered several high earth fences to be built at the entrance to the tunnels to prevent rainwater from pouring in.

It's just that the rainfall in western Sichuan is obviously beyond the expectations of the secret fire. The Mongolians, who live in arid and semi-arid areas all year round, obviously have never seen such a torrential rain, and it has stopped and stopped for several days in a row.
