Chapter 511

Snowflakes fell all over the sky, and the northern prairie was covered with a silver quilt.

The gentle army of the northern expedition was trapped.

Because of the snow, there was a vast expanse of white around, the road was indistinguishable, and the severe cold in the North made the sergeant unbearable, so the plan of the northern expedition was delayed.

This is hard for the logistics officer.

One hundred thousand troops, people eat horses and chew. Every day is a terrible number. It's ok if you just rest for a few days, but depending on the weather, don't want to start this winter.

After a winter's supply of grain and grass, old fan of the logistics camp felt that he was going to collapse.

In the account of the Chinese army, the stove was burning in the old area and complained to Su Lu.

"Dushuai, the road from the South has frozen, and the road is difficult to walk. The team transporting luggage will be ten days in the evening. Lord, our grain and grass reserves are getting less and less."

Old fan's face was bitter and he was about to cry.

Not only the road of the northern expedition could not be taken, but also the road of transporting supplies from the south.

Su Lu put down his military affairs booklet and looked at Lao Fan speechlessly:

"It's not a terrible thing to transport luggage. You won't ask how the people of the North transport things in winter. It's not too easy to get some sleds and skates that can slide on the snow."

Old fan looked confused and didn't understand what sledge and skate were.

Su Lu said it again. Seeing that old fan was confused and was about to pull a pen and paper, old fan suddenly jumped up with a cry.

"I, I was burned by the stove."

Old fan said with a smile on his face, but his eyes twinkled.

"Lord, do you think it would be more convenient to use birds to transport baggage?"

"As far as the last general knows, we have birds that can transport more than a dozen people. If we can load food and grass, we must also load a lot. Moreover, if we can expand the birds, we can transport more food and grass."

Su Lu's popularity is waning. This old fan, woodlouse's method is not yet clear, he is thinking of getting high technology.

"OK, I already have plans in this regard. Many bird soldiers have been eliminated from the original bird camp. It is just right to control this kind of flying bird transporting baggage."

Lao Fan beat his thigh and said excitedly, "Wang Ye, at last, he will go to the bird camp, and his royal highness certainly supports the minister's idea."

Without waiting for Su Lu to speak, old fan rushed out. The cold wind with snowflakes flew in along the opened curtain and let Su Lu swallow his words again.

Although Lao Fan died, he tossed about if he wanted. The winter in the north is fucking cold.

Su Lu leaned his chair against the stove again, continued to pick up the military affairs booklet and began to read it.

"Hoo"

The curtain was lifted again, and Su Yun rushed in wrapped in a cold wind. His cotton hat was full of snowflakes and his cheeks were full of excitement.

"Brother, I think of a new type of flying bird. You can give me the money to try it out."

Su Lu didn't look up and continued to read the military affairs booklet. Although it was winter, the training couldn't stop. As for Su Yun, it must be the transportation of birds mentioned by old fan just now. As long as he mentioned birds, Su Yun became interested. Now he must be planning how to pit the money in the army.

Su Yun didn't answer Su Lu. He looked around and saw that there were only two bodyguards in the account. The rest of the main paperwork went out for training. He simply dragged a chair and sat down next to the stove.

"Brother, Taoist Zhenyuan's improved new flying bird can fly more than 100 feet in the sky, and the flying distance has reached more than 50 miles. I think if the internal breathing conversion cabinet is made larger and the internal structure is made more refined, will the flying bird fly higher or farther?"

"It may fly farther, but there is little hope of higher."

Su Lu put down the military affairs booklet and said that this is an improvement direction for birds in the future. If they don't make improvements in this aspect, they will certainly make improvements. Since they have an Academy of Sciences, they will certainly not be just a decoration.

Su Yun looked at Su Lu in surprise: "you know it before it's made?"

"If you can fly far, you can certainly fly higher. I think you're wrong."

Su Lu waved: "OK, go find Taoist Zhenyuan and let him try. I'll approve it if it doesn't exceed 10000 Liang."

Su Yun slapped: "great, old fan is willing to give 10000 Liang to improve the transportation of luggage. Brother, you give 10000 Liang. I'll spare 10000 liang from our house later. This larger internal breathing conversion cabinet must be a success."

Su Yun said, turned excitedly and left. He went to Houying to find Taoist Zhenyuan.

Fifteen days later, a larger internal breathing conversion cabinet was made. Because the army had nothing to do, with the cooperation of the whole army, a larger flying bird was also made.

Looking at the birds almost the size of a camp, Su Lu felt dizzy.

"Taoist Zhenyuan, are you sure this bird can fly?"

Old Taoist Zhenyuan rubbed the birds with his hands, and his face was full of anxiety: "it's hard to say. Although the internal breathing conversion cabinet is more refined and the weight of internal breathing conversion is higher, he really has no bottom in his heart about how much weight birds can fly."

Su Lu also has some headaches. It just can't do without professionals. In the past, when he did his own research and development, he always based on reality, first assumed the goal to be achieved, and then carried out the actual design. Generally, the design margin should reach twice the required margin or even more.

Now it's good. The old Taoist priest directly touched the stone and began to cross the river. He doesn't care whether the other side of the river is his own destination or not, let alone the surplus.

"Install it first."

Su Lu ordered and said, success or failure is the accumulation of experience.

After the installation of the internal breathing conversion cabinet, the first commissioning of the bird was started. Old Taoist Zhenyuan went in and made some internal breathing. He was sure that the internal breathing conversion channel inside the bird was normal and smooth, so he jumped out of the bird.

Su Yun skillfully drilled in, grabbed the control lever, took an internal breath and began to urge the birds.

"Hoo Hoo"

Huge flying birds flapped their wings, the surrounding snow was blown disorderly, and snow particles hit their faces, causing pain.

Slowly, the bird began to rise, but to everyone's surprise, the bird only slightly flew 15 or 16 meters high, then completely stopped cooking, hovered in the air, and no matter how Su Yun spent his internal breathing, it would not rise any more.

Old Taoist Zhenyuan pinched his beard and his face was full of amazement. How could it be such a situation? According to normal, there is no problem for this thing to fly 200 feet.

Nima has only flown less than ten feet!

"Try how far you can fly?"

The old Taoist urged Su Yun to say.

The bird flew a hundred meters in the air and then fell slowly.

"How much interest can your royal highness have?"

The Taoist asked Su Yun.

Su Yun's hands were wrong, and a palm force gushed out. He smashed two big fingerprints on the snow. Su Yun took out a small ruler from his pocket and measured the pit.

"Should be able to fly for three or four hours"

Su Yun hesitated. According to the calculation in the past, he should be able to fly for another eight hours, but his internal breathing did not increase. How could this bird fly for so long.

Su Lu's eyes lit up when he looked at birds the size of a barracks.

If you can fly for four hours, that is, eight hours, even if Su Yun's internal breathing is high and the internal breathing of ordinary bird soldiers is different, you can fly for about five hours. If four bird soldiers alternate, the bird can fly for 20 hours.

In twenty hours, even if the bird flies slowly, it can fly from Yumen to Hanshui city.

It's a good thing to transport goods.

If we expand it to trade between the north and the south, those precious fur, pearls, silk and seasonal fruits can be from south to North at once. The value in it is immeasurable.

This is a good opportunity for military to civilian.
