Under Fu Yan's guidance, hundreds of sergeants picked up pickaxes and shovels and planed out a big cave at the foot of the mountain, but it was still all hard red clay......

"No, Wanchun, are you sure this is the entrance?" Seeing that nothing was found, Xiao Chen couldn't help but wonder, was he wrong?

"This is the dragon's mouth, the entrance and the exit, just such a mouth." Fu Yan was there with the old god behind his back, and his expression was not panicked.

"But this ......" Xiao Chen didn't finish speaking, and he heard a few sergeants in the cave shouting, which sounded like cheers?

Several people hurriedly rushed in, only to see two huge iron doors behind the mountain wall, and a bronze lock the size of the Eight Immortals Table on it, with several big characters chiseled on it, and the thirteen warehouses of the Han Dynasty.

smashed open the bronze lock, hundreds of people shouted the trumpet before pushing the big iron door open, the sun shone in, but saw that it was densely packed with grain bags, the surrounding space was huge, and I couldn't see the edge at a glance, and when I looked up, it was more than ten zhang high, and the grain bags were stacked to the top......

When I opened a bag, the white rice in it flowed to the ground in an instant!

Not only rice, but also corn, sorghum rice, millet, black beans, soybeans......

In addition to rice, there are also foods that can be stored for a long time, such as honey, dried meat, dried fish, dried flour cakes, and dried vegetables, which are sealed in ceramic jars.

There were also countless iron arrowheads, swords, guns, swords, halberds, all wrapped in thick lard, the lard had changed color, but the weapon was still as sharp as ever!

"Haha, this grain can still be eaten!" Tie Kunlun grabbed a handful of rice and put it in his mouth, chewed it a few times, and there was a smell of rice!

In fact, as long as there is no decay and weathering, these rice can be eaten even if they are stored for more than ten years.

The hardness of those dried meat and dried fish dough cakes is comparable to that of iron, the big guy picked it up and tried to bite it, but he couldn't gnaw it at all, only Xiao Ye's teeth were good, he chewed a piece of dried meat raw and swallowed it into his stomach, blinking his eyes and shaking his head again and again, this taste is really bad......

"It's going to have to be soaked in water for days before it can be eaten." Tie Kunlun said, "My God, I think this food is enough for 100,000 people to eat for several years!" ”

"At the beginning, the Emperor of the Han Dynasty was ambitious and wanted to completely conquer the northern frontier, so he stored so much food and materials in Yanyun County, but it was not used until the end." Li Tanhanami.

"Brother Wanchun, you have made a great contribution." Wei Yuntian ignored Fu Yan's weak body when he first recovered from his serious illness, raised his hand and slapped him on the shoulder more than a dozen times in a row, almost slapping Fu Yan again and vomiting blood.

"It's not just a merit, it's also a merit, how many people in Yanyun County can be saved by these grains." Xiao Chen said.

"But how can so much grain be transported to all parts of Yanyun? We don't have that many carts and mules. While being happy, Wei Yuntian frowned again.

This belongs to the sorrow of joy.

But it is indeed a big problem, seeing that it is going to snow, the road is definitely not easy to walk, and the weather is cold, and it is extremely difficult for people and horses to move, and now the temperature at night is already more than ten degrees below zero, and it may reach minus 30 degrees in a few days!

And Yanyun County runs nearly thousands of miles from east to west, and so much grain transportation is really a big problem.

However, it is necessary to transport the grain out as soon as possible in time, and it will be too late after the spring of next year.

"It can be transported by water." Qinglong Captain Gongsun Ban said suddenly.

"Water transport?" Everyone listens to it so freshly.

"I've seen it before, the Bailongjiang River hasn't frozen yet, and we can transport grain along the river to the east, transport it to various riverside cities to unload, and then distribute it from there to various places." Gongsun Pandao.

"Gongsun Ban, have you forgotten something?" There were three black lines on Wei Yuntian's forehead.

"Well, what?" Gongsun Ban was stunned.

"Boat! You didn't say it was going to be transported by water, I asked you where the ship was? Wei Yuntian said loudly, "Don't tell me that you want to make Ang!" ”

"There are many ways to transport by water, and you don't necessarily have to use a boat." Gongsun Ban said with a smile.

"General Wei, don't you know that rafts can also be loaded with things?" Liu Tiejian on the side said.

"Raft?" Wei Yuntian scratched his head, okay with that?

"Gongsun, what are you going to do? Let's go into details. Xiao Chen hurriedly invited the two great craftsmen to sit down, and he would like to hear the details.

Niutou Mountain is rich in high-quality wood, which is a necessary material for construction and has a wide range of military uses.

The local garrison would cut down a lot of timber every year, but because Yanyun County had been fighting non-stop all these years, it didn't transport much out of it.

Now Niutou Mountain is full of large logs piled up like small hills, which have long since dried thoroughly after years of drying.

Now Yanyun County is in ruins and needs a lot of wood, Chen Jisheng knows that Niutou Mountain is rich in high-quality wood, and he also talked about it with Gongsun Ban and other craftsmen, and Gongsun Ban suggested water transportation at that time.

The way of water transportation is also very simple, dozens of large logs are tied together, that is, a wooden raft that can drift with the river, and then find some experienced raft supporters, how much wood can be easily transported out.

If you don't even need a raft to save trouble, you just throw the wood in the river and let it drift with the river, as long as you stop it downstream.

Such a large log is dozens of bundled together, the carrying capacity is comparable to a cargo ship, and under the heavy load, the raft will never turn over, and it is now the dry season, the river is gentle, and there is no strong wind, there is also a northwest wind, just smooth wind.

"Talent! Absolute talent! Xiao Chen was really overjoyed to hear Gongsun Ban's method, but he couldn't think of such a simple method.

This task is up to you, this is the most important thing at the moment, do you want people or everything to you!

I'll temporarily make you the official of Caoyun!

All the logistics units in the army are all deployed and used by you, and if you don't have enough manpower, I will send you more.

As for what to do, you masters can discuss it yourself, and you don't have to ask me, I will be responsible for supporting you.

Gongsun Ban is also vigorous and resolute, and in the afternoon of the same day, he began to lead his craftsmen to set up camp by the river, and then mobilized a large cart to transport the timber from the mountain......

Blacksmiths made a batch of iron hooks to secure the rafts, and carpenters made logs into the shape of houses, filled them with food and other supplies, and then capped them......

This is no longer a raft, but a square cargo ship, with strong airtightness and strong structure, theoretically it will never sink!

The only downside is that there is no power, and they are left to drift on their own, but this is the upper reach, and no matter how they drift, they will eventually reach their destination.

Of course, it was necessary to build some small rafts to carry people to follow, and once these grain ships ran aground in the bend of the river, they had to be pushed back into the river by manpower.

In addition, hundreds of people were sent to follow along the riverbank, and once a blockage was found, it was necessary to dredge it in time......
