Everyone looked at Koji Yoshi, waiting for his shocking words.

"Firearms are strong, but they have three weaknesses.

One firearm is afraid of water, and it is difficult to use it when it encounters water, but unfortunately the rain in Jizhou is scarce, otherwise as long as it rains heavily, Yecheng can fall in an instant.

Second, it can only shoot directly, such as a crossbow, if it is a field battle, you can build a thick armor shield, advance slowly, close hand-to-hand combat, although Ma Ziyu's firearms can be added to the short sword for hand-to-hand combat, but the combat power is extremely low, not as good as a spear and halberd.

The third is that firearms cannot fight for a long time, and the last general observed that the firearms on Yecheng City have not launched more than 20 consecutive attacks, just like the archers cannot shoot for a long time, firearms will lose their combat power if they are used for a long time.

Therefore, if you want to break Ye City, you can win authentically. ”

"Nonsense! If Ming Gong hadn't waited for Mr. Xu's gunpowder, he would have blown up the city wall through the tunnel! Zhang Yan was given a blank look, and her anger became even greater.

Such a disdainful look was all too familiar to him.

When he was a child, those heroes looked at him with such eyes.

Of course, most of the heroes who have seen him were reduced by him later.

"I'm talking about authenticity, but I don't use firearms."

"That's... How to break the enemy? ”

Yuan Shaolai was interested.

"Our army can dig more than a dozen trenches at the same time, the trench should be deeper than one person, the earth and stones are piled on both sides of the trench, and then the wooden planks are laid, and the sergeant walks under the trench, so that the bows and arrows and firearms on Yecheng will pose no threat to our army.

As for those artillery pieces and throwing cars, how many times can they hit in the face of thin trenches? When it was found useless, I thought that the defenders of Yecheng would give up this method of warfare themselves.

In this way, when the trench is dug to a hundred steps under the city, it can be dug horizontally, and the equipment such as the Lu bus and the rushing car should not be built anymore, only need to build a ladder, and all the sergeants will attack with a ladder, and they must disperse and gather in front and back, a hundred steps away, a few breaths will come, and then attack it with elites? We will be able to break the enemy! ”

"Ahh Yuan Shao patted his thigh? Excited little hands are shaking.

"O you! I almost blamed my henchmen on the wrong way!! ”

Oh, it's your henchman at this time... Just now, Ming Gong, your expression was obviously suspicious.

Yan Liang and Wen Chou said that they were very tasteful.

But who told Koji that he could use his brain? Even if the frustrated teaching, trial and others listened to Koji Yi's tactics? I also think it is feasible.

Yuan Shao asked Koji Yi to prepare for the attack on the second day.

The next day, under the city of Ye.

Xian Yufu looked at Yuan Jun who was approaching quickly with a stern face? These Yuan Jun were unusual, and they didn't use those bulky Lu buses anymore? Instead, you chose a lightweight ladder of all colors? Holding shields, they rushed forward in a scattered manner, and behind them, there were large armies? It gave the defending sergeants a lot of psychological pressure.

"Trebuchet ready! Artillery ready! Musket ready! Bow and crossbow ready!! ”

With the military order issued? First, the artillery launched a bombardment, but as judged by Koji Yoshi, the artillery was extremely ineffective against the extremely scattered sergeants, and the two rounds of shelling did not hit a few people at all.

"Trebuchet for gravel! Artillery for shotguns! ”

Xian Yufu immediately ordered a reload.

Boom!

Bang Dang!!

In the midst of a loud bang? Countless gravel and small lead bullets smashed into Yuan Jun, this time? Much better with the sound of gold? Yuan Jun left hundreds of corpses and retreated, and several times more Yuan Jun was smashed and his head was bleeding? Gotta go back and bandage it.

Test?

It's rare to see today's Yuan Jun so anticlimactic? Something felt wrong.

In the Yuan army on the opposite side? Ju Yi looked at the several wooden shields brought back by the sergeant, dug out the lead bullets on them with a dagger, and then asked the details carefully, and suddenly had a number in his heart.

"According to the thickness of this wooden shield, cover all the trenches, and organize thirty teams of sergeants to dig fifteen trenches vertically, and dig through horizontally every hundred steps!"

Soon, the dust was all over the sky, and Yuan Jun was digging trenches everywhere, and Yuan Jun's abnormal movement made Ma Qiang also go out of the city tower to observe.

"It's... Trench? Ma Qiang looked at the trenches that were stretching towards the city wall, and he felt that his eyes were about to fall out.

The learning ability of the late Han Dynasty is too strong.

You said that you also found the formula for gunpowder by chance, anyway, gunpowder was first invented in the Tang Dynasty, and there was only a gap of five hundred years from the end of the Han Dynasty, so I pinched my nose and recognized it.

But I used firearms, and you began to use the trenches of the First World War?

Then when I get the machine gun, are you going to fight with me in depth and intersperse?

In fact, in ancient times, there were not no trenches, in history, Gongsun Chan dug a large number of trenches and mounds to defend Yijing, but just like Gongsun Chan used trenches for defense, trenches were dug by the defender in ancient times to block the enemy's attack, and the attacker used trenches, very rarely.

"Ming Gong, is it to dig these trenches to cover up other tunnels?" Xian Yufu's thought made the people around him tremble.

If Yuan Shao really dug a few tunnels to blow up the city wall, then the originally planned urn city would be completely useless.

"Fortunately, Lu Yi was transferred to Yuan Tan by Yuan Shao before..."Ma Qiang was also a little afraid, there were no less than 150,000 Yuan troops outside the city, and they really poured in, even if they could be blocked, the more than 20,000 soldiers and horses in the city would have to fight.

"Unless they already know we're building the Urn City, they don't have to." Ma Qiang looked around with a telescope for a while and said, "They don't blow up the city wall until now, it should be that the gunpowder is still on the way, and the Liyi dug these trenches because they wanted to take Yecheng without relying on gunpowder." ”

"Just these trenches?" Xian Yufu snorted: "He underestimated our Northern Army too much!" ”

"Don't underestimate these trenches." Ma Qiang knew how difficult trench warfare was in later generations, and to a certain extent, the Shangganling Battle to Resist US Aggression and Aid Korea in later generations was actually a kind of trench warfare.

"You see, these trenches are laid with a lot of planks, and the thickness of the planks I don't think is thin.

I don't think most of our ranged attacks will be effective, unless we hit the trench directly with artillery or catapults, but this trench is very narrow, and the chance of hitting the trench must be very low, and it will not kill most of them except for wasting our ammo.

However, the Yuan army can use these trenches to quickly advance under our city walls and then launch a surprise attack. ”

Ma Qiang was very familiar with the style of trench warfare, and immediately said Koji Yi's plan.

"This Yiyi, it's really not simple, he knows that our troops are insufficient, so he dares to fight like this!"

Xian Yufu and others also reacted, although there were more than 20,000 defenders in the city, there were still too few soldiers and horses outside the city, and once they lost the advantage of long-range attack when defending the city, they would fall into the disadvantage of hand-to-hand combat.

The city is offensive and defensive, and the defenders are most afraid of falling into a long period of hand-to-hand combat, I can beat you, and if you can't beat me, it is the dream of the defenders.
