In Pharmacist Li's mind, under such a cold weather, in order to avoid a large reduction in soldiers due to frostbite, even daily training should be stopped. Pen & Fun & Pavilion www.biquge.info and the winter battle, the consumption of logistics grain and grass is particularly amazing, the war drags on for a long time, and the army consumes amazingly, which is probably not the way to win. It is necessary to fight quickly and find fighters to kill the enemy in one shot, so that you can win.

Before Li Yaoshi set off with his troops, he played against the emperor alone. Li Shiluan asked him directly about his strategy to break the enemy, and Pharmacist Li replied at the time: "The ministers should seek an opportunity to severely damage the main force of the Liao State, and strive for a quick victory." The climate of the grassland is extremely cold, which is extremely unfavorable to our soldiers, and the Tuliao cavalry has lived outside the fortress for a long time and the bitter cold is not hindered by him. In the case of one and the other, we must not delay for a long time, and it is beneficial to fight quickly. ”

But since Pharmacist Li came to the garrison camp, what he has seen and heard is completely opposite to what he thought before. The Dingbei garrison had no intention of fighting a decisive battle with the Tuliao State, but slowly repaired the fortress all the way without hurrying and slowly advancing forward.

Pharmacist Li saw it in his eyes, anxious in his heart, but helpless. He had several opinions before meeting the two regiment commanders, but the deputy regiment commander Li was desperate and refused to agree to a quick solution. Pharmacist Li once dragged Li Deyi to ask the reason, and Li Deyi said at the time: "If you fight quickly, the Tuliao people will be scattered in a hurry after being defeated." If I plan to wipe out his clan, I have to move forward slowly, steadily fight under the city of Tongwan, and surround and destroy it. ”

Li Yaoshi said: "If you fight quickly, after the defeat of the Tuliao tribe, they will inevitably scatter and flee. At that time, it will be swallowed up by other tribes in the grassland, why should Deputy Head Li waste his efforts in vain? ”

"You have a plan for a while, but you can't plan for the future. If I raided the city of Tongwan, I defeated the Tuliao people. The Tuliao tribe fled in all directions, and the rest of the steppe tribes may be able to annex it, or they may be annexed by it. A few decades later, there will inevitably be another generation of male lords on this grassland, and then it will be another catastrophe for the people in Guannai. A general like you, a powerful figure in the Tang Kingdom, is naturally not afraid of these. But for a small people like me, it is a catastrophe. I can't bear to see him again, so even if I spend ten times more effort and a hundred times more effort, I must finish my work in one battle, completely exterminate the Tuliao people, and eliminate future troubles forever. Li Deyi said, as if he was recalling the catastrophe in the last years of the Pingzhou Dynasty, and his eyes were actually a little red.

But Pharmacist Li, who was fighting next to him at the time, only felt the blood-like killing intent on Deputy Head Li's body.

Since then, Pharmacist Li has put out the idea of a quick battle, and began to honestly follow the garrison to slowly advance. Anyway, now that the grain and grass are also supplied, the garrison regiment has also given him a lot of cotton jackets (all of which have gone through the accounts of the Dingbei Labor Dispatch Company), and the soldiers can also endure the bitter cold.

Pharmacist Li never expected that the unhurried and unhurried actions of the Dingbei Garrison Regiment before were all suspicious tactics! After two months of silence, when Tongwancheng was already paralyzed, suddenly the whole army was dispatched and quickly advanced.

Moreover, the timing of the dispatch of the Dingbei garrison regiment is also very good! After the heavy snow spread over the grassland, the whole world knew that in this harsh winter, it was impossible to march quickly, and they all thought that the garrison would patiently wait for the next year's snow to melt before continuing to advance.

The Dingbei Garrison Regiment suddenly took action at this time!

In addition to sighing with emotion, Pharmacist Li also hurriedly ordered the whole army to be fully equipped and ready to fight at any time.

When Li Deyi arrived with the elite cavalry, the construction site was in full swing. Some of the soldiers were responsible for boiling hot water. Some of the soldiers held a square wooden box in their hands, opened on one side, and several soldiers next to them patted the snow with wooden shovels, and then shoveled it into the wooden box, and then a soldier poured freshly boiled hot water into the wooden box, and the hot water melted the snow in an instant, and after a while, it was frozen into solid ice by the severe cold. If you do it a few times, an ice brick will be ready.

Then, there was a special engineer battalion soldier who used equipment to transport the ice brick away and placed it on the ice wall that had been built more than one person high.

Li Deyi looked at the tea work, and the ice wall grew a foot higher.

Li Deyi, who is familiar with "The Romance of Taizu Dingchao", is also very familiar with this scene. Because in "The Romance of Taizu's Rebellion", it is clearly written that Taizu, the founder of the Pingzhou Dynasty, took advantage of the cold weather in winter to build a city overnight, so as to resist the onslaught of the opponent the next day, and finally successfully reversed the situation, repelled the opponent, and took advantage of the situation to expand the land for more than 1,000 miles.

Unexpectedly, the Dingbei Garrison Regiment would one day use this trick.

When Head Liu saw his junior brother, he waved him over. Since this was the first time that the garrison regiment had built a fort with ice bricks, Commander Liu was not at ease, so he personally came to the site to supervise the work.

"Senior brother, it's really good! With this trick, we can build a fortress in a few days, and we don't have to urge the people to transport timber from the rear in the cold weather. Li Deyi said happily.

In the harsh winter, the grassland has turned into ice, and the freshly boiled hot water is taken out of the tent, but it will be frozen into ice lumps after five breaths. Under such severe cold, it was already a very arduous task to deliver food from Dingbei County to the front of the garrison regiment, not to mention the transportation of wood, masonry and other materials used by the garrison regiment to build the fortress. Even if the garrison regiment paid a lot of wages, the people who transported the grain were a little unbearable.

Therefore, in the past two months, Regiment Commander Liu has been slowing down the construction of the fortress, on the one hand, to relieve the pressure of logistics and transportation, and on the other hand, to paralyze the ten thousand cities, so that Fan Guoshi and Ashina Huo'er think that the garrison regiment has nothing to do with this cold climate and has been stopped by the harsh winter.

However, in fact, Regiment Leader Liu had deliberately arranged all this illusion to show the Tuliao scouts sent by Tongwancheng, and he had already planned today's surprise action.

Commander Liu was able to think of this trick, and he had to thank Li Deyi for insisting on vigorously promoting the book "The Romance of Taizu Dingchao", which is a true thing, not a fiction.

Since the four-wheeled carriage described in the book was built, Liu Tuan Chang has also begun to pay attention to the book, and no longer thinks of it as just a boring pastime novel. Not long ago, there was no war, and Regiment Commander Liu picked up the book on the case and read it.

The head of the world-famous garrison regiment, of course, has to relax in his spare time. After all, Regiment Leader Liu is only in the transcendent realm now, and he is not yet a saint.

This look really made Head Liu see the way. Commander Liu was greatly inspired when he saw that Taizu, the founder of the Ping Zhou Dynasty, built a city with ice, built a city overnight, and defeated a strong enemy.

After a secret experiment, he was very sure that Regiment Leader Liu finally decided to build an ice castle and quickly move forward! Before taking action, the Dingbei garrison regiment must first make a good appearance and let Tongwancheng relax its vigilance.

Before August, Tongwancheng sent tens of thousands of selected forward cavalry, and even Ashina Huo'er personally went into battle, wanting to intrude and block the advance of the garrison, why? It's not just to stop the garrison in this bitter cold, under the blizzard of this grassland.

At that time, Regiment Commander Liu happened to make a plan, since Tongwancheng thought that the heavy snow could stop the garrison, then he might as well make a show. When Tongwancheng thinks that the garrison has been hindered by heavy snow and severe cold, and then suddenly advances, it will definitely give Tongwancheng a big surprise.

Of course, even the elite soldiers of the Dingbei garrison regiment have to pay a considerable price to build a fortress under such severe cold.

Working in such a cold winter requires a great deal of physical exertion on the soldiers. In order to reduce the pressure on the soldiers, Regiment Commander Liu rotated the soldiers into four shifts, working only for three hours a day.

The winter days on the grassland are not only very cold, but the days are also very short, only less than three hours. The daytime is short, although the construction speed of the ice brick fortress is slowed down to a certain extent, but the work time of the soldiers of the garrison regiment is also relatively shortened, so it can save some physical strength and always maintain a high work efficiency.

The first ice-brick fortress was completed in less than ten days, but Captain Liu did not dig the underground grain depot this time. First, it is too difficult to dig in winter, which will delay the construction period. Second, this place is only more than 800 miles away from Tongwan City, and for the sake of safety, it cannot be used as a grain storage fortress for the time being.

The garrison regiment's operation was very secretive, and Commander Liu also specially issued a white cloth cloak to each of the soldiers who were working, and draped it behind their backs as a cover. The soldiers of the garrison regiment jokingly said that this was to mourn the Tuliao State, and when this fortress was repaired all the way to the city of Tongwan, it would be the day of the demise of the Tuliao State.

While the garrison regiment quickly built a fortress, in order to prevent Tongwancheng from discovering the actions of the garrison, Li Deyi was entrusted by the head of the regiment Liu to intercept and kill all the Tuliao scouts on this cold grassland.

In order to avoid the leakage of information, it is necessary to intercept and kill all the Tuliao scouts, and none of them can be spared. Even if this has been done for a long time, Tongwan City will inevitably notice the abnormality. How many ice-brick fortresses can be repaired during this period of time depends on the ability of the garrison regiment.

Although the order is only a few words, it is by no means easy to put into practice. In order to prevent the actions of the garrison from being exposed, it is necessary to intercept and kill all the Tuliao scouts within 300 miles of the side.

In order to achieve this goal, Li Deyi had to brave the wind and snow with 53 students and 600 Beiwei troops to insist on cleaning up the snow-covered grassland within a radius of 300 miles every day.

In the past ten days, Li Deyi could only rest for one hour a day, and after ten days, the whole person had lost a lot of weight, and Uncle Hummer actually showed some fatigue rarely. And Li Deyi's fifty-three students were even more tired enough, and the war horses under their crotches had to be rotated twice a day. Zhu Biao and Liu Ying, two boys, only participated in the first day of inspection, and they were so tired that they didn't get up all day the next day.

After three days of inspection, Li Deyi divided them into two shifts of 300 people, and they took shifts.

After the construction of the first ice-brick fortress was completed, Commander Liu ordered the whole army to rest for a day. Li Deyi still can't rest, he still has to insist on patrolling. But at this time, the 20,000 Yi cavalry drawn from the rear grain road had arrived, and Wang Meng began to take them to inspect and set out, and Li Deyi could rest for an hour before setting off.

While resting, Li De faced the gold bricks, holding a saber in his hand and shaving the beard that had accumulated on his face in the past few days. Now Li Deyi has also begun to grow a beard, and he has been busy patrolling for the past ten days and has no time to shave, but it has been quite long, and the shape is the standard treacherous and slightly curved mustache. Sure enough, whoever has a face.

As soon as he finished shaving his beard and put down the saber in his hand, a herald came to give the order, asking Li Deyi to go to the regiment commander's tent immediately to discuss matters.

"Come, you're tired these days, aren't you?" When Captain Liu saw his junior brother coming in, he stretched out his hand to beckon his junior brother to come to the sand table.

"Hehe, it's just that I've lost some weight, and nothing else." Li De replied with a smile.

"Come and see. If we advance another two hundred miles, we will be less than seven hundred miles away from Tongwan City. I plan to speed up the construction of the fort and build two more ice castles by the beginning of November. What do you think? Head Liu opened his mouth to ask for the opinion of his junior brother.

"Senior brother, although this ice castle was built very quickly, it cannot be used as a long-term fortress, and when the weather is warm next year, I am afraid it will be dissolved." Li Deyi voiced his concerns.

"I've thought about it for a long time. The winter is long, and it takes until the end of April and the beginning of May for the snow to melt. We can still use this ice brick fortress for more than half a year, which is enough. Head Liu said with confidence.

As soon as Li De heard that there was something else in his senior brother's words, he turned to say: "Now that there are Yiren cavalry to help with the inspection, I can finally make it easier." Senior brother, don't worry, I will never let go of a Tuliao scout! Continue to build two fortresses, no problem, I guarantee that the news will not leak! ”

Commander Liu said: "Let's build two forts in front of us, continue to move the camp forward, and wait until it is close enough to Tongwan City, and then give Fan Guoshi and Ashina Huo'er a New Year's gift!" Let's see how he copes! ”

"Hehe, when the time comes, I can't say that I will have to go to Tongwan City every once in a while." Li Deyi began to bubble up again.

With the experience of building the first ice fort, when building the second ice fort, Regiment Commander Liu commanded the construction site to be more proficient, and the soldiers of the garrison regiment worked more smoothly, and the construction was completed in only eight days.

Then came the third ice-brick fort, which was finally completed on November 5.

So far, Tongwan City still doesn't know what's going on outside. Recently, the number of casualties among the scouts sent to the desk of Ashina Huo'er, the regent of the Tuliao Kingdom, has been increasing, but Ashina Huo'er, who is busy consolidating his power, has no time to care.

Since Ashina Huo'er became the regent, Fan Guoshi has not had the slightest contact with the military intelligence of the Tuliao scouts. He could only secretly send his own fine work to reconnoitre. But Fan Guoshi's meticulous work is not a professional scout after all, and it is okay to spy on information, and it is not easy to carry out reconnaissance missions in this kind of ice and snow. All the fine works sent out by Fan Guoshi were intercepted and killed by Li Deyi and his elite cavalry, and none of them escaped the net.

Until now, the two people in Tongwan City still knew nothing about the sudden action of the Dingbei garrison. Fan Guoshi felt a little strange about the successive casualties of the meticulous work sent out to reconnoitre. But it was no more, now he couldn't move at all, he had to wait for the opportunity, and the troops in his hands were all lying on their stomachs silently, for fear of attracting the attention of Ashina Huo'er.

After the construction of the two ice-brick fortresses was completed, Regiment Commander Liu immediately ordered the whole army to rest. At the same time, he secretly transferred Wang Meng to command all the Yiren cavalry, risked abandoning the rear grain route, and guarded outside the garrison camp to guard against attacks from Tongwan City.

After the army rested for three days, seeing that there was no movement in the city, Commander Liu decided to send an engineer battalion to build an ice brick camp wall and build a new camp with ice as the main thing and a small amount of wood.

This time, Li Deyi took the elite Beiwei army, 3,000 elite cavalry of the garrison regiment and 20,000 cavalry to escort the engineer battalion until the construction of the new camp was completed and the rear army arrived.

On the eve of his departure, Regiment Commander Liu secretly told his junior brother to be careful against a surprise attack by a small group of elite cavalry sent by Tongwancheng.

After Li Deyi arrived, he carefully followed his brother's orders, took precautions day and night, and even insisted on patrolling without sleeping for two or three days, lest he be attacked by the Tuliao cavalry.

However, until the construction of the new camp was completed five days later, Li Deyi did not see a single Tuliao cavalry.

The new camp of the garrison regiment, built next to the third ice fortress, was only twenty miles away, and it could be used as horns for each other to support each other in wartime.

After Commander Liu arrived with the main force of soldiers and horses, he immediately found his junior brother and asked if there was any trace of the Tuliao cavalry in the past few days.

Looking at his junior brother, he shook his head and said that he didn't see a single Tuliao cavalry, and Commander Liu almost didn't believe it.

In Tongwan City, the newly appointed regent Ashina Huo'er is facing a thorny big trouble, and he can't even take care of the garrison for the time being.
