The siege spine mainly withstands four types of attacks, one is arrows, the other is fire, the third is falling rocks, and the fourth is gold juice and boiling oil.

Considering the size of the siege vertebra, the wooden planks are thick and dense, and the defensive arrows are sufficient.

As for fire, after the Tang and Song Dynasties, there was fierce fire oil. A barrel of strong fire oil was poured from the top of the city, and the siege spine was poured over the whole car. Then a torch was thrown, and with a bang, the siege spine was burned directly. It was a fierce fire.

Oil is especially scary.

Nowadays, in the late Han Dynasty, it is impossible for the defenders to obtain fierce fire oil. The closest fire-making material that can be found in the late Han Dynasty is tung oil.

Tung oil also catches fire with a bang, but although the fire of tung oil is fierce, it is not as fast as fire oil. Therefore, when the siege spine encounters tung oil, taking precautions in advance can effectively avoid the fire.

Preparation in advance can be to add a covering layer on the top of the siege cone, such as cast iron. The Iron Army does not have it now, so there is no way to use metal covering.

In addition to skinning, you can also pour water and wet mud on the siege spine, which can also prevent fire.

Especially wet mud, the effect is excellent.

Then, the siege vertebra needs to be protected from falling rocks, and the siege vertebra needs to be strong enough. In Li Mengxi's opinion, the four siege vertebrae are large and solid, so their sturdiness is not a problem.

As for the last point, the siege vertebra must protect against the initiation attack of golden juice and hot oil. This requires that the top of the siege vertebra is dense enough and cannot be soaked by water.

Li Mengxi jumped off the siege spine, walked down, walked under the shed roof, and looked up. He saw that the inside of the shed roof was tightly covered with a layer of cowhide. He could tell at a glance that it was cowhide because the hair was not shaved off.

Woolen cloth.

No wonder it's dark inside when viewed from the outside, with all the light blocked.

According to the test procedure, you should take a bucket of water and pour it from the top to see if there is any water leaking.

But when Li Mengxi saw the airtight appearance of the cowhide, he felt that there was no need to try it.

Anyway, you have to put mud on the outside. The mud is very dense and can also isolate the golden juice and boiling oil.

After the inspection, there is no problem with the siege spine.

Li Mengxi came out of the siege spine and told everyone, "Wet the mud with the Marauder. We will attack the city tomorrow and put a layer on top to prevent fire and golden juice initiation."

Everyone on the side took note of it.

Li Mengxi looked at Lu Li and asked, "Where is the wooden umbrella?"

"Here." Lu Li called to the carpenter and brought over a giant umbrella-shaped instrument.

The equipment is similar to the big parasols used by small vendors. It has the same shape, size, and height.

It's easy to make a big umbrella-like thing out of cloth. It can be made out of wood. How to make it? Li Mengxi looked up at the wooden umbrella and was particularly curious.

The wooden umbrella lay flat on the ground, and Li Mengxi was able to get closer and take a closer look. He could see clearly that the carpenters used a troublesome tenon structure to piece together the wooden boards into the umbrella surface.

After counting, the umbrella has eight sides, made of eight wooden boards, each of which is about the same size.

Li Mengxi was surprised that the craftsmen in the Carpenter Camp were so skilled.

Wooden umbrellas are used for battlefield rescue teams. Their main function is to provide the rescue teams with necessary protection, that is, to prevent arrows.

Li Mengxi touched the edge of the wooden umbrella. The surface of the wooden umbrella was two fingers thick and looked very thick.

"Lu Li, what kind of wood is this?" Li Mengxi asked the slave standing behind him.

"It's elm." Lu Li replied.

Elm, commonly known as elm knot, has a dense texture and is a relatively hard wood among common tree species. There is no doubt that elm of the same thickness is much more defensive than willow.

Li Mengxi felt that he had to give it a try. The rescue team had no armor and no shield in their hands. If the wooden umbrellas were not strong enough to defend themselves, the rescue team's battlefield survival would be a problem.

He took the most powerful big yellow crossbow in the army, took five steps away, and fired directly at the wooden umbrella.

The crossbow machine was triggered, the crossbow string clinked, the crossbow arrows flew out with a whooshing sound, and with a "click" sound, the crossbow arrows were nailed to the wooden umbrella.

I went to check and saw that the iron crossbow arrow had penetrated the wooden board, and half of the arrowhead was exposed.

Has the defense failed?

No defense succeeds.

Just like armor, whether the enemy attacks with swords, spears, stabs, or crossbows and crossbows, if the armor is broken, it may not be able to cause effective damage to me. The attack must penetrate the armor and penetrate more than one centimeter deep to cause effective damage.

An attack needs to penetrate one centimeter of armor to pass through the gaps in the armor, through clothing, and through the outer layer of skin and muscles of the human body to cause damage to vital organs.

Otherwise, when the sword came down, the armor was broken, and the sword did hit the body, but it only made a small cut on the skin. This is not an effective injury.

Such a minor injury would not have any impact on a soldier's combat effectiveness.

This is true for armor, and so is defensive equipment.

It does not mean that if the instrument is penetrated, the defense will fail.

If the instrument is shot through, the arrow cannot get stuck on the instrument. It has to pass through. If it can't pass through, the arrow must maintain a certain speed, so that it can cause damage to the person hiding under the instrument. Otherwise, after the arrow passes through the instrument, its strength will be reduced.

It can't even penetrate layers of cloth, and it has the lethality of a ghost.

To sum up, the most powerful big yellow crossbow can shoot directly at a distance of five steps and cannot penetrate the roof of the wooden umbrella shed. This defensive power is enough to withstand most of the arrow rain attacks faced during sieges.

With the equipment in place, we can attack the city tomorrow.

If the wooden umbrella is insufficient, it is still insufficient. The wooden umbrella is too heavy and cannot be held by one person, nor is it very stable when held by two people. It is fine on flat ground, but I am afraid that when used on the battlefield, if one of the umbrellas is tilted, the umbrella will be damaged.

It fell, and the rescue workers were all exposed to the hail of arrows.

For this reason, Li Mengxi felt that it was necessary to add a stable structure and add two or three more legs to the umbrella, so that even if the umbrella was crooked, it would only be supported on the ground and would not fall over.

The siege equipment has been built, and the carpenters have no work to do. They just want to improve the wooden umbrellas.

In a blink of an eye, it will get dark.

Because we will attack the city tomorrow and have been practicing frequently in recent days, the soldiers are tired. Therefore, we will let the soldiers rest early tonight.

At night, when Li Mengxi followed Guan Yu to inspect the camp, because it was still early, he found that many soldiers were not sleeping at all, but talking nonsense.

Li Mengxi told Guan Yu, "Soldiers cannot control themselves and must be disciplined.

This chapter is not over yet, please click on the next page to continue reading! Just like in the carpenter camp before, the carpenters worked from dawn to dusk in order to get rewarded food, without any restraint.

At that time, I discussed with Duke Xuande that this was inappropriate.

It's okay for carpenters to get up early and work late on weekdays, but if they are still tired and uncontrolled when making tools, they will be exhausted and exhausted. When making tools, how can they not be in a trance and make mistakes?

If during the siege, the equipment cannot be used due to some minor mistakes, it will harm countless soldiers.

Therefore, I made an agreement with Mr. Xuande that no matter how tight the construction period is and how heavy the tasks are, everyone in the crafts camp should not get up earlier than dawn and go to bed no later than... well, ten o'clock.

In the middle of the day, an hour must be set aside for the craftsmen to rest. At this time, everyone in the crafts camp must rest and no one is allowed to be busy.

This is a way to ensure that the equipment is excellent and error-free.

Just now, General Guan and I were patrolling the camp and saw that the soldiers who will attack the city tomorrow will chat endlessly at night and do not recharge their batteries. When they attack the city tomorrow, they will be tired and exhausted, won't they harm themselves?"

Hearing this, Guan Yu nodded thoughtfully.

If the soldiers cannot control themselves, they will be restrained by military orders.

Guan Yu then found a whip and went to patrol the camp again to see who was up late at night and chatting nonsense, so he went straight into the tent and yelled at them.

Guan Yu's roar echoed in the camp, and all the soldiers quickly climbed into bed to sleep, no longer daring to talk nonsense.

This problem discovered by Li Mengxi is actually very important.

Take a professional boxing match as an example. The day before the match, the players will definitely ensure adequate rest and sleep. Otherwise, when they get to the ring, they will be inattentive and slow to react, making it easy for them to be knocked down.

Two opponents with equal physical strength, skills and experience, if one had enough rest the day before and the other had not, then the difference is huge.

This is true for boxing matches, and it is also true for life-and-death fights on cold weapon battlefields. The more you get enough rest, the faster you react, which may be the difference between life and death.

This also highlights another bigger shortcoming in the army. There is no lights-out whistle, and all the soldiers in the battalion do not have the self-discipline to rest early. There may even be some guys who, ignore them, spend the whole night burning wheat around the campfire.

.

Then they attacked the city the next day. This guy didn't sleep all night, yawned again and again, and went to attack the city.

How much harm can such a weak guy cause?

If this guy was driving for the coach, because he was sleepy and unable to concentrate, and then he fell asleep while the car was jolting, the road was dangerous and mountainous, and the coach, car and people were all taken to the cliff in one fell swoop.

.

The harm would be smaller. The man who stayed up at night was feeding the horses to General Pan Feng. However, because he was dozing off and too sleepy, he was lazy and stopped feeding the horses. He hid away and slept, saying that he would wake up after a while.

Hey. As a result, I accidentally overslept and forgot to feed the horse. Then General Pan Feng rode his hungry horse to fight Hua Xiong, but his horse power was not good enough and he was chopped down by Hua Xiong.

Loss or not?

Even younger, this guy who stayed up all night was a carpenter. When he was building siege equipment the next day, he was very sleepy. When he tied the siege ladder, he was absent-minded and the ladder was not tied tightly. So, the attacker

When they were attacking the city, the siege team carried a ladder to attack the city. The ladder fell apart within two seconds.

The guy who was in charge of tying the steps, if he was careless, would have killed more than a hundred people.

If he were younger, he would be nothing more than an ordinary soldier attacking a city.

If you don't sleep all night, you will inevitably yawn again and again the next day. You can't stop yawning.

As we all know, when you yawn, you cannot see it with your eyes and cannot hear it with your ears.

This guy was yawning frequently. As he was yawning, suddenly a stray arrow came. Others heard the stray arrow and hurriedly avoided it, but he didn't hear it, and then he died.

It is no exaggeration to say that turning off the lights and whistle can significantly reduce casualties during wartime.

The lights-out signal is not a simple curfew, the curfew is to prevent people from leaving the tent and running around at will, and to not care whether people in the tent are sleeping or talking.

Therefore, in addition to the curfew order, there must also be a lights-out order. If the soldiers cannot discipline themselves, military law must be enforced.

The lights-out whistle is because there are lights and whistles, but in ancient times, there were no electric lights. It can be slightly changed, it might as well be changed to [Quiet Whistle].

When the whistle blows, those who should rest must rest. Whoever keeps chattering will be governed by military law.
