Hearing the news sent by Manu, Yelu Aguzhe knew that Wanshengjun held back and did not move, and it turned out that he had started from the north first.

Someone said that all the military rations in Xianghe City had been burned. Now there were 7,000 men and horses, and only a few days' rations were left to be distributed to the battalions. The grain of the people in the city had already been collected and gathered in the granary, and who knew that this fire would be burned all at once.

"What does that beast look like?" Although Agu Zhe believes in gods and Buddhas, he always feels a little strange.

"The divine beast was three zhang in size, flew thirty or forty zhang high, flew in mid-air and entered the city. Specially selected grain depots to burn fires. "The people who came to talk about the divine beast that burned the grain depot that day, and suddenly came to the spirit, since he could be sent by Manu to ask Agu Zhe for food, he naturally had a good eloquence, and when he encountered the birth of a rare divine beast in a hundred years, General Agu Zhe wanted to hear it again, and he preached even harder: "That divine beast is dressed in silver armor, and there is a golden crow body, and it walks against the wind......

"How did the divine beast burn down the grain depot?" Aguzhe asked, interrupting the gushing and colorful interpretation of the story.

"This ...... The villain didn't know, but he heard a loud noise, and the villain followed General Manu out of the room, and the granary smoked. When we arrived outside the grain depot, the fire had already burned the yard of the grain depot. The visitor replied honestly.

"How does this beast know where the grain depot is? Could it be that you are not strict in guarding? Aguzhe asked again.

"The grain depot is strictly guarded. It's just that at night, someone always runs to rub some food with the guards they know and go back to cook and eat—could it be that the divine beast is annoyed by this? The visitor guessed to himself.

"Where else did the beast burn?" Aguzhe asked impatiently.

"I didn't burn anywhere else, but I spit a rocket at the city wall when I left-General, please send someone to send some grain and grass! Xianghe City has run out of food. "The visitor finally remembered what he was doing here.

Of course, Manu sent people to ask Aguzhe to send someone to send grain, but if he knew more, he would not give it, even if he could send two hundred stones of grain? 200 stone is not enough, 100 stone is also fine!

But Aguzhe doesn't have much food of his own now, let alone a hundred stones, and fifty stones can't be evened out. He has more people here than in Xianghe City, and it costs sixty stones for people to eat every day. He sent someone to ask Xiao Gan for food last time, but Xiao Gan didn't say anything and didn't give it.

"Hold on for a few more days, Wansheng has few soldiers, and they don't dare to attack the city, as long as Wansheng's army goes back for the Spring Festival, I will send someone to send food over." Aguzhe said to the visitor.

"Ask the general to give me some grain, now the whole city is in a panic, and they all know that the grain depot has been burned." The people who came were still begging.

"It's not that I'm ruthless and don't sympathize with you," Agu Zhe said embarrassedly: "You naturally saw it when you came, on both sides of the road, there are sentries of the Wansheng army, if I send someone to send grain over, the people of the Wansheng army will definitely come to attack the grain cart, but the two thousand cavalry come to the north of the city every day to run around." We just can't hijack the grain truck, it's a fire, it's us who feel distressed! ”

"When the villain came, General Manu also said that he was willing to attack Guoyin City before the grain ran out, which not only drove away the Wansheng army, but also captured the grain and grass. I only have 20,000 horses, and I can always do it when I attack a small county town with less than 4 or 5,000 people. Seeing that Aguzhe could not send food over, the man sent by Manu said in a different way.

"Attack Guo Yin City?!" Aguzhe asked in disbelief, "Does Tamanu think that he has a long life?" If the Wansheng army is easy to clean up, the emperor will not be forced to leave Yanjing with his troops; If the Wansheng Army is cleaned up, will I still stay in the city? He Wanshengjun has explosive arrows in his hands, it would be good if he didn't come to attack your Xianghe City, and he still wanted to run to the door to let people fight, it was really boring. ”

"Then why didn't the Wansheng army come to attack the city?" The man asked stupidly.

"I think you're hungry, aren't you? He burned the grain depot and starved you for a few days, how can you fight him? He can take Xianghe City without losing one person, why do you want to let you attack Xianghe City when you are full? Aguzhe laughed angrily and scolded.

Thinking that the grain and grass in Xianghe City had been exhausted, Aguzhe sighed and said: "Bear with it for a few days, the cattle and sheep in the city will be brought first, and they will slowly fill their hunger, but it is really not good, so they will go directly to Jizhou to ask for food." There is still a way out. ”

When the people who came saw that Agu Zhe was right, they did not dare to transport grain out of the city, and if there were fewer people to protect the grain, the Wansheng army would rob the grain; If there are too many people to protect the grain, the Wansheng army will burn the grain; If Agu Zhe dared to send a large team of men and horses to transport grain, the Wansheng army was afraid that it would come to attack Anci City. Seeing that Agu Zhe had arranged a way out, he hurriedly agreed to come down and went back to Xianghe City.

Now Zhou Nan just asked Gao Yuan and Yang Keshi to send outposts every day to continuously inspect the roads leading from Xianghe City to Jizhou and Anci City, in case these two places were transporting grain to Xianghe City. As long as there is no grain and grass, or the movement of troops and horses, the rest does not matter. As long as you don't carry food, it doesn't matter how you send letters back and forth.

In this way, most of the Wansheng Army can stay in the city every day and recuperate.

Zhou Nan was also very concerned about the question raised by Gao Shouxiao. If the wind direction had changed slightly, the effect of burning the grain depot would not have been so good.

However, later generations did not have a good way to control the direction of the hot air balloon, so they could only plan the general route, and then after the hot air balloon took off, the recovery vehicle below followed the hot air balloon. If it could be controlled, it should have been applied to hot air balloons a long time ago.

However, the airship of the same type as the hot air balloon is equipped with an electrically propelled propeller thruster. It can be seen that the propeller thruster can also change direction on the hot air balloon. If there is no electricity, there will always be manpower, right?! Don't make big sharp turns, just change a little in the left and right directions.

Zhou Nan immediately ordered someone to bring the carpenter who was just boiling fish and maw glue in Gu'an City to Guo Yincheng, and told the carpenter about the appearance of the propeller blades with a picture.

Soon the carpenter made a three-bladed propeller, the propeller is connected vertically to a wooden stick through a wooden shaft, and the wooden stick has a grip at one end, and the propeller blades can be rotated by shaking the grip. The three-foot square propeller blades are installed outside the willow frame, and Zhou Nan and Gao Shouxiao used a hot air balloon to try it out, but they can't go against the wind, but they are still very flexible in controlling the left and right movements.

With the blessing of the propeller blades, the magic car is finally completed.

Moreover, Zhou Nan inadvertently let the appearance of propeller blades also make Zhou Nan think of the electric fans of later generations, as well as the boats propelled by propellers.

After Pingzhou was conquered, the territory expanded to the seaside, and the propeller-driven god ship was naturally completed.
