"90 % of the stones?"

After listening to the report of the assistant, Liu Tie frowned.

In this siege, the role of heavy crossbow was greatly reduced, and the stone casting car became the main force of remote attacks.

But he limited the number of grenade and fire oil, and the darts and female soldiers could only fill the stone in the stones.

In this way, the stone consumption becomes faster.

When the supplies were reserved, Zhang Liang and Liu Tie did not expect that someone could destroy the airship, so there were not many stones in reserved.

From the eyes of everyone, there are a combination of airship and grenade flash bombs. The probability of the enemy dares to attack Chongqing Guancheng is too low!

Where would I think there would be such a day?

But now it's too late to regret it.

Liu Tie stood on the city wall and was full of anxiety.

The stone casting car is the main combat power of the city today. If there is not enough stones to fill it, then the stone throw car will become a bunch of furnishings!

Thinking of this, Liu Tie hammered the city wall fiercely.

The next second, his eyes suddenly lit up.

"Come, notify the logistics camp, remove the house where no one in the city lives, and dismantle Lao Tzu, and transport the masonry built in the house!"

When the Chongqing City was occupied by Dong Man for decades, when Zhang Liang led the Northern Expeditionary Army to win the city, the Dongman nobles followed Shan Yu to run away a lot, and they were captured by the Northern Expeditionary Army.

labor.

Last time, Dong Man made the organization to organize these captives to launch a riots, causing the seven granary in the city to be burned out, and the device library was almost broken.

Zhang Liang was extremely angry about this. After suppressing the riots, he ordered a large cleanup of the Caido Captain.

At that time, the East Capture in the city either participated in the riots directly or assisted. After cleaning, the owner in the city was almost killed by Zhang Liang.

After investigation, he found that in addition to the captives of Dongbara, there are some Central Plains slaves who assisted and participated in the riots.

These people have been slavered by the East barbarians for too long. Even if the Northern Expedition has captured Yuguan City and returned freedom to them, but some people's slavery has penetrated into the bones, and when the old master of the old man will still be afraid of underground underground underground

kneel.

The old master asked them to participate in the riots, and they participated.

For these people, Zhang Liang was not soft -hearted, and he executed them with the riot owner!

At the same time, this incident also woke up with Zhang Liang, so that he realized that he could not leave these slaves in Yuguan City anymore.

Later, the steam ship came to Yuguan City to send food. Zhang Liang sent the Central Plains slave in the city and asked the steam ship to pull them to Dujiangyan to repair the water conservancy.

After Wei Datong learned the identity of these slaves, he placed them alone in one place, and sent someone to stare at them.

After a period of observation, Wei Datong found that the slaves were performing well.

No one wants to be a slave. After leaving the nightmare, Yuguan City gradually forgot that the tragic memory and started a new life.

Then Wei Datong withdrawn the person who stared, but arranged for other villagers nearby to pay attention.

Anyway, the place where he placed these people is a small basin, surrounded by steep mountains, there are only two roads in and out.

There are levels set up by militia on the two roads. Even if these people still have Dongbai, there is no moth.

Zhang Liang received a letter from Wei Datong, and was very satisfied with this arrangement.

After the East Capture was executed, and the people of the Central Plains were removed, the current Yuguan City was completely become a veritable military city, leaving only more than 5,000 people in the Northern Expeditionary Army.

Even if one person is allocated a courtyard, he cannot live in a city.

What's more, Zhang Liang would not let the Northern Expeditionary Army disperse like this. Instead, he cleared an open space near the northern city wall as a school ground.

To the west of the school grounds is the area where the powerful Eastern barbarians gathered in the past. There are many large houses left behind. Zhang Liang renovated the two largest houses among them and used them as dormitories for bodyguards and female soldiers.

Usually, the bodyguards and female soldiers are either on duty on the city wall, practicing in the open space, or resting in the dormitory, and rarely go to other places in the city.

This resulted in many empty houses in Yuguan City.

If these houses are demolished, wouldn't the bricks and stones be used as filling materials for catapults?

Following Liu Tie's order, the logistics battalion immediately began to demolish the houses.

The Eastern Barbarians have been attacking the city for two consecutive days. Many bodyguards and female soldiers think that they have withdrawn their troops now and will not continue to attack until tomorrow at the earliest.

But who knew that not long after they started demolishing houses and transporting bricks, the Eastern Barbarians would start the fourth round of siege overnight!

What's even worse is that it was completely dark and overcast at this time, and the moon was blocked by dark clouds. Looking down from the city wall, all you could see was pitch black.

There is a bonfire burning on the city wall, and the enemy can easily see the escorts on the city wall by looking up from below.

After Liu Tie discovered this situation, he immediately ordered a catapult to eject the kerosene jar, regardless of the kerosene reserves.

Not to stop the enemy, but to illuminate.

Otherwise, the enemies would all run under the city wall and they would not be able to see clearly.

As baskets of kerosene jars were smashed out, Liu Tie finally saw clearly the situation on the grassland.

Just like during the day, at this time, the grassland was full of densely packed heads, running towards the city wall.

At this time, just relying on the logistics battalion to demolish houses and transport bricks and stones would definitely not be enough for the catapults. Liu Tie immediately sent someone to call back the escorts and female soldiers who were taking turns to rest, and helped the logistics battalion transport the bricks and stones together.

Fortunately, when the city wall was renovated, craftsmen sent by Mancang built several simple cranes on the city wall in order to transport the heavy catapult base to the city wall.

With these cranes, the logistics battalion no longer has to climb stairs to carry bricks and stones to the city wall.

Just send the dismantled bricks and stones to the crane, and then use the crane to lift them to the city wall. The escorts and female soldiers on the city wall will then use small carts to transport the bricks and stones to the catapult.

Although there is lighting from the kerosene altar, the visibility at night is still much worse than during the day. The number of enemies rushing to the bottom of the city wall is much greater than during the day, which puts a lot of pressure on the bodyguards guarding the city wall.

In two places, due to the carelessness of the escorts, the enemy actually climbed up the ladder.

Although the enemy was repulsed in the end, more than half of the bodyguards guarding these two places suffered casualties.

In order to reduce the casualties and pressure on the escort, the catapult must maintain a faster throwing frequency than during the day.

Even if there is a crane, even if the bodyguards and female soldiers who are taking turns are pulled up, the masonry transported can only be enough for a catapult.

This situation lasted until late at night.

Those who came to attack the city at this time were basically cannon fodder, and most of them didn't even have any decent clothes.

The winter nights on the grassland were so cold that they could carry them during the day, but at night, many cannon fodders were too cold to move even before they reached the city wall.

Perhaps the Chanyu of the Eastern Barbarians also realized that the casualties during the night siege were too great, and finally stopped the siege.

But all darts know that this is not the end.
Chapter completed!
