After all, coming from a family of military commanders, Qing Mulan has now realized the military advantages of hot air balloons.
Regardless of whether it is used for strong attack or defense, a hot air balloon paired with grenades is definitely a killer weapon.
At worst, it can be used as a lookout to observe the enemy's every move.
No wonder Jin Feng repeatedly emphasized to her to keep it secret when he left the city.
Such a big killer really needs to be kept secret.
"Eagle is not doing this for the first time. He knows who can use it and who cannot."
Jin Feng said: "You, on the other hand, have been so heartless all day long, so don't let me know."
"Don't worry, sir, I won't tell you even if you beat me to death."
Qing Mulan said: "But Mr. Wei and I won't tell it, nor will the hunter, but such a big bag is floating in the sky and can be seen from more than ten miles away. If it is leaked, don't rely on me."
"You reminded me..."
When Jin Feng heard this, he couldn't help but frown slightly.
Eagle usually trains to fly hot air balloons in inaccessible places.
There are not many people around Yulei Mountain due to continuous flooding.
But there are not many places like this in the places they want to survey next.
Jin Feng didn't have a good solution for this.
"Forget it, I'll try my best to conduct surveys at dawn in the future. If that doesn't work, I'll climb a mountain to observe."
The hot air balloon is one of Jin Feng's biggest trump cards and cannot be exposed easily.
Moreover, the most important part of this project is around Dujiangyan. Now that it has been clearly observed, other places can be surveyed according to the old method.
In the next few days, the group went to investigate other surrounding places before returning to Xichuan City.
"Why did you come back so quickly? How was the survey?"
Although the Ninth Princess had never been exposed to water conservancy, she knew that this was a big project and thought that the two of them would have to investigate it for a long time.
As a result, he came back within a few days, which made the Ninth Princess a little doubtful whether Wei Datong had seriously investigated.
"The survey results are all here!"
Wei Datong took out a thick stack of papyrus from the package and placed it on the table.
A detailed topographic map was drawn on the grass paper, and where trenches needed to be dug and where dams needed to be built were clearly marked.
The Ninth Princess looked over the map carefully and said slowly: "The survey is very clear. How did you do it in a few days?"
"Of course I have a way." Jin Feng smiled and said: "As for what method, don't ask. I assure you that these maps are real. They were drawn stroke by stroke by Mr. Wei and I after on-the-spot investigation.
from!"
"I can prove it." Qing Mulan said: "We have exhausted four horses in the past few days!"
"Thanks for your hard work!"
The Ninth Princess did not ask Jin Feng for specific methods, but looked at Wei Datong with a smile.
"No hard work, no hard work!"
Wei Datong quickly waved his hand: "As long as I can find a way for the people to make a living, I am willing to be a low-ranking official even if I am as tired as a war horse!"
"Then what do you think, Mr. Wei, of the survey results? Is the method proposed by Mr. Wei feasible?"
"It works, it works, but..."
"Just what?"
"It's just that this project is too big, much bigger than I imagined!"
Wei Datong took a map, pointed in the direction of Yulei Mountain and said: "Mr. Jin not only wants to drill through Yulei Mountain and build a treasure... Baopingkou, sir, is it called that?"
"Yes," Jin Feng nodded: "I plan to call this overall project Dujiangyan. In addition to Baopingkou, there is also Feisha Weir, which divides the water into fish mouth."
After saying that, he took out his writing brush and wrote the words Feishayan and Fenshuiyuzui on the map.
"Your Highness, Mr. Jin not only wants to build Dujiangyan, but also build artificial ditches on the east side of Yulei Mountain to divert the river water that flows through Baopingkou to the east of Yulei Mountain to Jiang'an River, Zouma River, Baitiao River and Qingbai River."
Wei Datong pointed to the map and found the locations of several rivers, showing them only to the Ninth Princess.
"Jiang'an River, Zouma River, and Baitiao River are all okay. They are not far from Yulei Mountain, but Qingbai River is far away. I'm afraid it will take dozens of miles of ditches to be built. This will require too much manpower!"
Wei Datong frowned and said.
"Master Wei, you are wrong. I not only want to build the area around Dujiangyan, but also other places."
Jin Feng took a new map from the study shelf: "These places marked in red must be repaired!"
"This this……"
Wei Datong was so shocked that he could not speak.
After a long time, he calmed down, stared at the map for a while, and said in disbelief: "Sir, if you build so many canals at the same time, I'm afraid it will take most of Sichuan and Sichuan to move!"
The canals marked by Jin Feng cover almost half of the Sichuan Basin, and together they are larger than the projects in the Dujiangyan area.
"Master Wei, under the circumstances this year, if the people are not allowed to move, what will they eat in winter?"
The Ninth Princess said: "As I said before, you just have to see if your husband's plan is feasible. As for money and food, I and your husband will find a way."
The area affected by the disaster was so large that almost the entire Sichuan and Sichuan provinces were affected.
The northern mountainous areas are relatively better, with higher terrain and rainwater quickly draining to the southeast.
Moreover, there are prey and fungi in the mountains. If it is not possible, there are more tree roots that can be chewed.
The most serious problem is in the basin in central and southern Sichuan. Almost all people make a living by growing grain. Without food, they can only starve.
Winter is only half over, and if there is no relief, God knows how many people will starve to death.
In addition to building canals, Jin Feng also needs to build roads in the northern mountainous areas.
In short, we can use as many people as we can.
"Let me take a look."
Wei Datong heard this and picked up the new map.
The new map marks are all canals, which are built in flat areas. Their main function is to connect water veins in various places. However, the amount of construction is relatively large, and there are no construction difficulties or barriers.
Wei Datong finished reading it quickly, nodded slightly and said, "It's feasible."
"Then fix it!"
Princess Ninth patted the table and made a decision.
There are many benefits to building water conservancy projects. It can discharge floods and prevent floods during floods. It can also store water during normal times. During drought seasons, the accumulated river water can be used to irrigate fields.
In fact, she and Jin Feng had discussed this plan before and came to Wei Datong just to confirm it again.
Jin Feng and Wei Datong were surveying the waters of Dujiangyan, and Ninth Princess and Qing Xinyao were not idle either.
At this time, all the food of the dignitaries has been in the hands of the Ninth Princess. In the past few days, the food has been transported to surrounding places with Xichuan City as the center.
The accompanying escorts, chamber of commerce and bank clerks were all well prepared and took action immediately upon receiving the Ninth Princess's order.
The area around Xichuan City, which had been devastated by hunger before, was suddenly filled with vitality in just a few days.
You can see various construction sites everywhere.
Some built brick kilns for Jin Feng, some built roads and bridges, and some built water canals.
The people of Sichuan and Sichuan are the most hard-working people. They are not afraid of getting dirty or tired, but they are afraid of not having enough to eat.
There was no need for bodyguards to supervise the work, and the people were very self-conscious, fearing that the bodyguards would dislike them for being lazy and drive them away.
I am also grateful from the bottom of my heart for Jin Feng who is willing to lend them food on credit and only charge very low interest.
