The weather in mid-October is not cold for Shudi, although the north is already snowy and frozen, but for the land of Yizhou, which is blocked by the Qinling Mountains, at best it can only be regarded as the late autumn season, and the coolness is getting stronger, but it is far from the extent that the ground is frozen and frozen.

On the top of Jingjun Mountain, Liu Yin could deeply feel the severe cold in the north, when night fell, the north wind whistled and blew on his face, like a knife cut.

It's cold in the heights! Liu Yin muttered a sentence, the climate is directly proportional to the sea dial, and the temperature drops by one degree for every meter that the sea dial rises? Liu Yin has forgotten the concept of geography, in fact, this is no longer important, how many meters higher Jingjun Mountain is than Chengdu, Liu Yin can not measure, in short, standing in this tuyere, it is very cold and cold, the cold wind is biting, so cold that people shiver.

"Young master, it's too cold here, why don't you make a fire for you?" Ma Fu's family general, Lou Wang, rubbed his hands that were red from the cold and said to Liu Yin.

"Nonsense!" Liu Yin said sharply, "The fire on the top of the mountain can be seen clearly dozens of miles away, do you want to tell Deng Ai that there are soldiers stationed here?" ”

The light of the fire can travel far at night, and lighting a fire on the top of the mountain is equivalent to building a beacon tower, which is clearly visible dozens of miles away, which is equivalent to informing Deng Ai that there are defenders here, so that Deng Ai can be on guard, is there anything worse than this?

Lou Wang was stunned, this consequence was something he didn't expect.

Liu Yin's expression softened, and said: "You go down and inform the ministries that it is strictly forbidden to light a bonfire, if you feel cold, you can go into the sheepskin tent and squeeze it." "On this expedition, Liu Yin brought some sheepskin tents, and when it was close to winter, Liu Yin still made some preparations, in addition to keeping warm tents, each soldier was equipped with cold-proof clothes.

In this era, there was no such thing as cotton, but silk was produced in Shudi, and a trace of silk was filled in the jacket, which was light and warm, and the only drawback was that the price was too expensive.

Lou Wang puffed out his chest and said loudly: "Back to the young master, we are not afraid of the cold!" ”

Liu Yin has a personal experience of how cold it is on the top of the mountain, but he is very satisfied with the mental state of the private soldiers, Liu Yin smiled indifferently and said: "The Wei soldiers will definitely not be able to come tonight, except for the patrol posts, everyone should go to the tent to keep out the cold." "After several days of long marching, the iron-clad troops will also be tired, and proper rest and recuperation will help to restore the physical strength and energy of the soldiers, which is especially important when the war comes.

As soon as Lou Wang left, Zhang Le came over with his arms dangling and grinned: "Big brother, if you don't go back to the camp to rest, why are you drinking the northwest wind here?" ”

Liu Yin glanced back at him and said, "In the end, you are fat, it looks like you are really not afraid of the cold." ”

Zhang Le smiled and said: "Fat has the benefits of being fat, how about it, now you have experienced it?" It's not me who blows, let's stand here for a night, and it must be you who freezes tomorrow morning. ”

Liu Yin smiled and said, "Look at you, that's good, you will be here tonight, and I will go back to the camp first." ”

"Don't-" Zhang Le hurriedly said: "Didn't you say that Wei Bing would definitely not be able to come tonight, and you really want to leave me here to drink the northwest wind?" ”

Liu Yin patted him on the shoulder and said, "Tease you, let's go, go back." ”

Due to the limited tent with him, Liu Yin and Zhang Le Zhao Zhuo squeezed into a room, although everyone felt that it was inappropriate, Liu Yin was very calm, since the expedition, Liu Yin has eaten and lived with ordinary soldiers, never engaged in specialization, and won the hearts of the military.

"Big brother, what are you going to do in this battle? Deng Ai has 30,000 soldiers, even if there are some losses on the road, the early 20,000s must be indispensable, and we have less than a thousand people to fight him for more than 20,000, but it's not easy? Zhang Le returned to the tent and first raised his own questions.

Liu Yin didn't answer him directly, but asked Zhao Zhuo: "Brother Zhuo, what do you think?" ”

Zhao Zhuo said: "Brother Le and I have similar ideas, we have all seen the terrain of Jingjun Mountain, if you only rely on mountain dangers, it should be difficult to block Deng Ai's more than 20,000 people, big brother should have a plan?" ”

Liu Yin smiled slightly and said: "Yes, it is not easy to defeat twenty or thirty times the enemy just by relying on mountain dangers, Deng Ai is a famous general in the world, he has been on the battlefield for a long time, and ordinary tactics will definitely not work to deal with him, but we have two major killing weapons: Yuan Rong crossbow and firearms, as long as they are used properly, it is not a dream to block Deng Ai at the foot of Jingjun Mountain." Success or failure in this battle, at this time the morale of the soldiers is the most important, starting tomorrow, the 900 troops will be divided into three teams, you and I each lead a team, take turns to hold the front line, no matter when the battle goes, we must not take half a step back. ”

Zhang Le and Zhao Zhuo immediately said proudly: "Big brother, don't worry, since we came here with you, we have no intention of going back alive. ”

"Good brother, for the rise and fall of the Han family, let's fight this one, people will win the sky!"

Three pairs of big hands, tightly clasped together.

In the next two days, Liu Yin commanded the soldiers to start building fortifications on Jingjun Mountain, according to the terrain of Jingjun Mountain, Liu Yin established three defensive positions, and divided more than 900 family soldiers into three teams, Liu Yin led a team, Zhang Le and Zhao Zhuo each commanded a team. In the face of Deng Ai's tens of thousands of troops, Liu Yin has already made a long-term plan to hold on, dividing the nine hundred people into three groups, which is the consideration of long-term combat, when fighting, one group fights, the second group waits as a reserve and is ready to reinforce at any time, and the third group is to sleep and rest. In order to conserve physical strength, the three teams rotate every four hours, day and night, the first group retreats to rest, the second group goes up to fight, and the third group serves as a reserve.

In this way, the physical strength and energy of the soldiers can be fully guaranteed, and it is foreseeable that once Deng Ai's attack is blocked, he will definitely launch a strong attack day and night, and if all the soldiers are transferred to fight hard, they will collapse if they can't hold out for two days. By adopting the method of rotating duty, it is possible to effectively conduct long-term operations.

Liu Yin has observed the terrain of Jingjun Mountain, and the road that can be passed is extremely narrow, and the large army cannot be used at all, and a group of 300 people can basically meet the needs of defense.

As for the fierce battle and heavy casualties, the troops will naturally be insufficient, Liu Yin has also thought about this problem, but the most important thing is to resist the first wave of Deng Ai's attack, so that he can have a chance.

At noon on the third day, the soldiers standing guard on the high ground noticed that there was movement in front of them and issued a warning flag, and the whole position instantly became tense.
