His subordinates are also not optimistic about their own future, Li Zhe doesn't know, in fact, he knows, I'm afraid he can't say anything.

At the moment of the great enemy, it is natural for one's own people to be unstable, and the blame is only for the enemy's strength, and the contrast between the strength and weakness of the enemy and the enemy is too great.

In the next few days, Li Zhe's actions made his subordinates even more puzzled, and he ordered his subordinates to pick up shovels and pickaxes that only engineers would use to dig deep into the land in the river valley.

Li Zhe also personally demonstrated to everyone that the trenches dug were all deep ditches that were one person deep and only allowed one or two people to pass through.

Under Li Zhe's personal supervision, the whole army worked quickly, but in two days they dug more than a dozen miles of long ditches, which were connected vertically and horizontally in the river valley, cutting the originally flat ground in the river valley into strips and blocks, almost making it difficult for people to move an inch.

Qiu Qing looked at it and said to Wang Degong:

"Feelings, our family commander is in a hurry, and he plans to dig a moat in this river valley to block the Mongols?"

Wang Degong was stunned when he heard this,

"Nonsense, just us people, can you really dig a river out in a few days? And even if we can dig a river, where is the water around it that can fill the entire river? ”

The two of them have been digging the pit with their own hands in the past few days, and a few blisters have been ground out in their hands, there is no way, look at the big boss Li Zhe is doing it himself, and there is no reason for them not to follow.

But with these thousands of people, it's okay to dig a few ditches, but dig a river? That would be pure delusion.

But Li Zhe obviously didn't let them dig a river, and when the three long horizontal ditches in the river valley were dug out, he began to move on to another process.

He ordered his men to mix the soil dug out of the trenches with water, compact and cut it into large pieces of mud bricks, just like the adobe bricks burned in the countryside villages, and put them in the river valley to dry.

But now that everyone is on the frontier and the military situation is urgent, where do you have the time to burn these bricks.

However, Li Zhe obviously didn't mean to let people burn these bricks, but when these mud bricks were slightly formed, they were built in one go, and behind a few horizontal ditches, an earthen wall was built, and this wall was also strangely built, only more than one meter high in total, roughly only to the chest of a person.

The adobe bricks were originally soft, and they could not build up the wall, but the wind that traveled through the valley was so raging, everyone only needed to put the bricks away with peace of mind, and splashed a few mouthfuls of water casually, and the cold wind blew and froze in an instant, and the earthen wall was frozen to be as strong as everyone imagined. Since the entire earthen wall is made of earthen bricks with a square foot, and the thickness is up to two layers, that is, there are two feet thick adobe bricks, so that when the final earthen wall is built, it stretches for more than ten miles, and it looks quite large-scale.

At this time, everyone in the army finally understood the mind of their own command.

Aren't these three trenches just a pit, and the earthen wall behind this pit is not the simplest city wall?

In just a few days, in the valley of the Mapingchuan River, everyone was able to make such a simple fortification, three trenches and a low earthen wall, across the middle of the valley, forcibly changing the terrain in the valley.

Now Wang Degong and others were completely impressed, who could have imagined such a whimsical idea as Li Zhe.

As soon as the terrain in the river valley changed, it was immediately like pulling up a city wall out of thin air, although the wall of this city wall was a little shorter, and there were no complex effects in the city wall in the past, but in this field battle, in the face of the Mongol cavalry, such a city wall effect was enough, after all, the Mongols were notoriously bad at siege warfare.

Speaking of which, the Song army, especially the regular Song army in Tianzhuzhou, has not built a city like this for many years, for many years, the Song army has been invincible in the field, and there is rarely a need to repair the city and build a walled city on the battlefield, and everyone has almost forgotten the Song army's housekeeping skills.

Well, with these trenches, and then there is such a section of the earthen wall, the Song army can hide behind the earthen wall and consume the Mongols far away, just with the ability of the Mongols, there are no dead and wounded thousands of people, it is impossible to break through this layer of barrier, this ditch wall seems to be very simple, but at this time, the effect on this battlefield will not be lower than a real male city?

The most important thing is to fight behind this earthen wall, the Song army's firecrackers can exert 100% power, and the unscrupulous people rush forward to disrupt the formation, almost like a natural spear formation in front of the firecrackers.

And the trap also made it impossible for the Mongol cavalry to run at all, and could not threaten the Song army, so they could only be beaten there stupidly.

The whole army, after seeing the completion of this ditch wall, the morale suddenly rose, everyone is not stupid, after seeing this ditch wall, who can not guess the function.

Being able to suddenly come up with this variable in this desperate situation, the Song army was like a shot of heart booster, and his whole body was full of fighting spirit again.

Even if we know that there is a huge disparity in the number of enemies and us, with this favorable terrain, our own army is almost as if it has doubled its combat strength out of thin air, it was originally 4,000 against 50,000 people, which is indeed difficult, but now it has been changed to 8,000 against 50,000 enemy troops, so it is not without the strength of a battle.

Previously, the army of only two or three thousand people broke the enemy camp of 10,000 enemy troops in one day, considering the endless means of their own commanders, the Song army suddenly had a feeling that their own victory was in hand.

This night, Wang Degong and the others got together again, and Wang Yanzi secretly touched Qiu Qing's shoulder and said:

"Huh? Have you heard of it? ”

Qiu Qingdao: "What? ”

Wang Degongshen's mysterious secret way:

"This Japanese army in Mengzhou City once had a legend in the army, although the head of our family is young, but the stars in the sky came to the world, born a famous general, the lower realm to assist King An, so there can be all kinds of magical means, I heard that it was originally just an ordinary student in Mengzhou Prefecture, and it was only four or five months to serve in the army? If you weren't born with talent, how could you be so powerful? ”

However, it was Wang Degong and others who finally inquired about the news that Li Zhe was originally in Mengzhou City, and showed it to Qiu Qing and Yan Guozhen.

The other two were also incredulous when they heard it.

Everyone already thought that Li Zhe was young, but no one thought that Li Zhe had just entered the army for only four or five months.

Four or five months of military seniority? can be promoted to the position of commander of this battalion, and can still play such a record on the battlefield, this is not a natural general, then what else can be regarded as a natural general.

And the fighting style commanded by Li Zhe is obviously very different from other Song troops, which adds a lot of mystery to Li Zhe.

In the past two days, the morale of the people below has risen sharply, and Li Zhe has noticed it, but the few trenches dug and a ditch wall built in this area can make the morale of the soldiers change so much, which still makes Li Zhe a little unexpected.

It seems that no matter how harsh the punishment and strict training of human soldiers are, after all, most of them are lucky, and they can destroy the enemy by hiding behind the wall and fighting, and there is nothing that the soldiers don't like.

However, the few trenches that everyone guessed were more than just a few simple pits.

People who did not experience the tragic trench warfare on the Western Front of World War I would never have imagined how terrible the power of these few trenches would be in modern warfare.

Trenches and breastwork, grenades, artillery and flintlock guns, these messy things are mixed together, and in Li Zhe's eyes, there is a sense of surprise that time and space are out of order, Li Zhe wants to see how the Mongols, who don't even have a few artillery, can break through this defense line!
