Seeing Li Mengxi's confused look, Guan Yu explained, "There are hundreds of soldiers gathered under the city, and it's not just these hundreds of soldiers. They all climb to the top of the city to fight, and there is always a sequence. Therefore, the ancestors borrowed the swords from the descendants, although the descendants did not have the swords.

, worry-free for half a day.

After half a day, maybe the city has been destroyed and there is no need for a knife.

If the city is not broken, borrow from the front and back, and borrow from the back and the back, and the borrowing will be endless. The soldiers in the front line of attacking the city will never have to worry about lack of swords."

After Guan Yu explained this, Li Mengxi finally understood.

In short, due to the time difference, there are a lot of people under the city. The first person to climb the ladder and the next person to climb the ladder may have to take a turn for an hour. After an hour, there will be another group of people following behind.

Therefore, when scholars from behind help those who came before, no one will ever lack a sword.

How to deal with problems on the battlefield can be so simple.

There is no need to bring a wedge, a hammer, or a pair of knives. The problem is solved with just one knife. Once the knife is blocked, the ladder will never slip even if it is placed on a slope.

Speaking of slipping, Li Mengxi looked towards the other end of the ditch. He saw that the slope under the city on the other side was not ordinary soil, but gray mud, which was hard and dense. It might be something like triple soil.

Er, that is to say, the slope under the wall on the opposite bank was not just dug casually, but a slope was deliberately built with great effort.

Look at the distance between the slope and the city, and then look towards the top of the city. If you drop a stone from the top of the city, it will fall right on the slope.

Then, when the stone falls down the slope, it will naturally roll down. At the end of the slope, there is a deep ditch. The stone rolls down and hits the ditch.

This slope is equivalent to extending the attack distance of the stone.

Thinking of this, Li Mengxi understood why Nanhe City was such a deep ditch, and why the far side of the city was an almost straight ditch that went straight up and down, while the side near the city had a slope instead. Originally, he thought that this slope

Isn’t it convenient to climb? It’s better to have both sides straight and steep.

Now I understand, the slope left behind makes the siege ladder slippery and difficult to stand firmly. Secondly, when people throw stones at the top of the city, the attack distance is actually limited. With a slope, the stones can be smashed 100% along the slope.

Go into the ditch.

I don’t know who designed this city, it’s so damn sinister.

Li Mengxi thought that this method was good. If we built a city in the future, we would also make a very deep pit like this. Leave a slope along the edge of the pit. The slope would be just at the distance where stones can be thrown from the top of the city, and then let the stones be thrown down along the slope.

Get out, the enemy soldiers screamed as they were smashed.

Li Mengxi was thinking happily, but there was a sudden click and another scream.

Li Mengxi turned around and saw that the ladder was broken.

Later inspection revealed that the ladder was an old siege ladder brought from elsewhere and had been damaged during the siege, so the ladder was broken by stepping on it while tossing it back and forth.

Li Mengxi frowned, what happened? It seems that there were a lot of broken ladders during this siege.

The shield warriors cut off a broken section of the ladder, and then tried to use the remaining long section to build it on the trench. When they tried it, they found that the siege ladder, which was originally very long, was not long enough after it was shortened.

It's not enough to get from one end to the other.

This reminded Li Mengxi that it seemed that, unlike the siege ladder, the siege ladder should be of the right length. It would be better for this trench ladder to be longer, leaving enough surplus. If it breaks, it should be immediately

You can move the broken ladder forward and continue to put it up. Otherwise, it would be too time-consuming to lift a new ladder from the back.

A ladder used to siege a city is a ladder, and a ladder used to build a trench is also a ladder. To make a distinction, Li Mengxi thought that the ladder set up on the trench moat could be called a "trench bridge".
