With Zhao Guangxiu's report, Jiang Guanyu couldn't help frowning.

He expected that the situation in Tiesai City would not be too good, but he did not expect that it had reached a situation where the city would be destroyed at any time.

Immediately, in the worried and mocking eyes of everyone, he said slowly: "Don't worry about the problem of grain and grass, it will be sent one after another, as for the city defense equipment, what kind of city defense equipment do we mainly lack?"

"Iron Fortress City originally had seven city defense crossbows, but under the attack of the wolf trebuchet, three of them have been destroyed."

"Bows and arrows are also in urgent need, and after defending the city for seven consecutive days, there is a serious shortage of arrows, and the remaining arrows are enough for a day at most."

"There were only 3,000 defenders in Tiesai City, and there were only 3,000 sets of ordnance in the arsenal......

As everyone took turns to report, Jiang Guanyu had a general understanding of the situation of the defenders in the city. After thinking about it for a while, he said, "I have summarized that the current situation in Tiesai City is generally facing the following difficulties."

"First, the city walls are in disrepair and are in danger of being breached at any time; second, there are insufficient weapons, and all the defenders cannot have a handful; the third is that the weather is cold and there are not enough cotton clothes; Fourth, the crossbow defending the city was seriously damaged; Fifth, morale in the city is insufficient, isn't it?"

"Yes, young marshal, these are the five major problems that I am facing in Tiesai City now."

Zhao Guangxiu nodded.

Although he still looked down on him as a new melon egg in his heart, Jiang Guanyu was still a little impressed that he could make a summary in such a short time.

"First, the city wall is in disrepair, and I will use the shortest possible time to requisition a batch of cement to repair the city wall. Second, the problem of the shortage of weapons is also very easy to solve, and a batch of weapons will be delivered tonight; Thirdly, the padded garments will also be delivered with the weapons, so you don't have to worry."

Speaking of this, Jiang Guanyu paused slightly: "As for the fourth, the problem of the damage of the city-guarding crossbow, you don't have to worry, I designed a more powerful city-guarding crossbow, and I have to trouble General Zhao to recruit skilled craftsmen in the city overnight to catch up with it."

As he spoke, he took out a design drawing from his arms and handed it to Zhao Guangxiu.

Zhao Guangxiu was a little unimpressed, but after receiving the design drawing, his eyes suddenly lit up.

As the garrison of the border city, although there has been no war for many years, at least the eyesight is still there.

Originally, the city crossbows were fixed to the city walls, which were not only cumbersome, but also extremely cumbersome to operate, requiring at least several warriors to control them.

The most important thing is that such a city-defending crossbow has no accuracy at all.

And the crossbow designed by Jiang Guanyu to defend the city uses a mechanical principle that he can't understand.

Not only is it much more powerful than the original city crossbow, but it also adds four pulleys to the bottom.

It has the advantages of small size, flexibility, high accuracy, and the convenience that one person can operate that the original city guarding crossbow does not have.

When the generals saw Zhao Guangxiu's face overjoyed, they gathered around to watch.

Everyone is a person who knows the goods, and when they saw this new type of city-guarding crossbow, they immediately exclaimed.

Jiang Guanyu couldn't help but laugh secretly when he saw that everyone looked like dirt buns.

Just kidding, the blueprint of the crossbow he took out was purchased from the system mall for a lot of points.

It adopts a noose design, which has the advantages of labor-saving, dexterity, precision, long range and great power.

According to the system, this kind of city-guarding crossbow that gathers the wisdom of the ancient sages of the previous generations has a maximum range of more than 3,000 meters.

Within kilometers, the accuracy can be as high as 100%; The accuracy can reach 90% within 2 kilometers; Beyond 2 kilometers, the accuracy will drop significantly, but it will also be about 50%.

It is no exaggeration to say that if it is taken by surprise, there can even be a decapitation operation, and it is not impossible to shoot the leader of the wolf rider directly.

"Someone!"

The more Zhao Guangxiu looked at the design drawings, the more excited he became, forgetting the existence of Jiang Guanyu, the young marshal, and shouted.

"The subordinates are here!"

The guards guarding the outside of the palace pushed the door in,

Bow down and answer.

"Pass my order, gather the craftsmen of the Ordnance Division, and then gather all the skilled craftsmen from the people in the city, and immediately rush to work according to the plan, and make the city crossbow overnight."

Zhao Guangxiu ordered excitedly.

"Yes!"

The guards took the drawings and quickly left.

"The problem of the crossbow guarding the city is solved, and the remaining thing is the problem of arrows, and this problem is not difficult to solve, so you just have to wait in peace."

After Jiang Guanyu finished speaking, he stretched his waist and said with a smile: "General Zhao, the matter has been arranged, please arrange a place for us to stay, so that we can also have a good rest."

"Okay young marshal, I'll let people arrange wine and food to catch the wind for the young marshal."

Zhao Guangxiu hurriedly responded.

"You don't need any food or drink, just arrange a few rooms for us to rest for a while."

Jiang Guanyu waved his hand and declined his kindness.

All the food he brought was purchased from the points mall, and although there were eight large trucks, which seemed like a lot, it could only solve the urgent need.

More than 100,000 defenders plus tens of thousands of civilians who were unwilling to leave their homes, and the rations of nearly 200,000 people were simply not something he could supply alone.

Zhao Guangxiu and the others saw that he had simply solved all the problems faced by Tiesai City, and they also put away their contempt.

When the best room in the garrison was vacated, everyone was arranged to move in.

"Jiang Guanyu, this General Zhao seems to be a little reluctant to give up power?"

When she came to the room where she was staying, Ning Qingyao said a little unpleasantly.

"Hehe, normal, it's not that he doesn't want to give up power, it's that we're too young."

Jiang Guanyu looked at it very much, and said with a chuckle.

"But if he doesn't delegate power, won't you, the commander of Youzhou, be hollowed out?"

Ning Qingyao said puzzled.

"Overhead? Hehe, it doesn't exist, I knew about General Zhao before I came, and this is a general who is extremely good at defending cities."

Jiang Guanyu said leisurely: "Professional things are naturally handed over to professional people to do, and it is taboo for a layman to command an insider, and I can rest assured that he will defend the city."

"So what are we going to do? Assist General Zhao in defending the city?"

Ning Qingyao became more and more confused, and asked with curiosity on her face.

"When it's hot...... No, can the pattern be enlarged a little, but we are on the mission of forming a Liberation Army."

Jiang Guanyu's eyes narrowed slightly, and he said confidently, "Our battlefield is not in Tiesai City."

"Where's that?"

When Xiaojing and the others heard this, they all came up and asked.

Jiang Guanyu smiled slightly, did not answer immediately, but asked someone to send two sacks of sand.

In the stunned eyes of everyone, it took half an hour to pile up a sand table with sand.

Everyone was shocked: "This-is Youzhou?"

"Yes, this is Youzhou."

Jiang Guanyu smiled, and after thinking for a moment, he pointed to a model of a city on the sand table and said, "This is the Iron Fortress City where we are."
