Li Yuanai did not rush to return to Bianzhou, but went to Gubailing, which the old man in Tangguan said.

Gubailing is located in the western section of Guangwu Mountain, which is known as Mangshan by the locals, and the terrain is particularly complex.

Li Yuanai and Yan Liben walked on the steep mountain road.

Li Yuanai said: "It's really suitable to lure Luo River into Bian? It's unlikely!" He also stomped his feet, which was tough.

Yan Liben also looked unbelievable.

This opens up a new river channel for Luoshui, and several key points need to be grasped, among which soil is the most important point.

It cannot be too loose or too hard. Too loose means that there is a lot of mud and sand, which can easily cause landslides and sinks, and will also produce immeasurable mud and sand, rush into the riverbed, causing bad effects. If the soil is too hard, it will be difficult to dig and dig. It will take three or five days for you to knock a hard rock, let alone millions?

Gubailing is steep and a narrow valley. If you want to open a river here, you must have to scatter the mountain valley. This hard soil layer, unless you spend a lot of money to dig like the Qin Emperor Kaichi Road, otherwise you will not be able to succeed in decades.

After walking a hundred steps, Li Yuanai saw that there was a collapsed small fortress on the right side, and couldn't help but smile: "I think this place is not suitable for riverbeds, but more suitable for war."

Luo Tong answered: "This is originally a battlefield."

"oh?"

Luo Channel: "The Guangwu Mountain in Xingyang is not only deep and steep, with cliffs and uneven cliffs, but also dangerous in Chenggao in the west, grains of Ao Cang in the northeast, and the important town of Xingyang in the south, which was the throat of ancient transportation and a place that military strategists must fight for. At that time, Xiang Yu, the overlord of Western Chu, and Liu Bang, were in Xingyang, near Guangwu Mountain for many years. There..." He pointed to the fortress on the right and said, "This fortress should be the remaining one at that time."

"Let's come here to have fun this time, let's go over and take a look."

Li Yuanai almost gave up. He thought that the old man might not know the details, and he could only understand it at all. He could not understand it. Whether the thoughts were really inconsistent, he had to go back to Bianzhou to find Jiang Zhiming.

When he arrived at the fortress, Luo Tong turned around and said, "This place should be a sentry tower. Before it collapsed, standing on this sentry tower, you can see the full view of the eastern section of Gubailing."

Li Yuanai's eyes fell on the broken leaves beside the fortress, and she slid with her feet, revealing a piece of yellow oiled paper that had been soaked.

This oil paper is usually used to wrap dry food such as oil cakes.

The oil paper has not yet rotted, and it is obviously not a thing left over from the Chu and Han dynasties.

Looking around, Li Yuanai found that the left side of the fortress could be climbed and said, "Mingda, you climb up, I'll do it later. Be careful..."

Luo Tong did not hesitate. He was agile and stepped onto the broken wall in just a few seconds. He tried his feet carefully, and it was quite solid. He reached out to pull Li Yuanai who was already preparing to climb.

With Luo Tong's help, Li Yuanai climbed up the broken wall and looked towards the eastern section. The situation in front of him was stunned: a giant valley that seemed to be split by an axe appeared in front of him: in the original valley, a mountain stream of about two feet appeared, all the way east.

"this……"

Li Yuanai has recently studied a lot of books recorded by the Ministry of Works on water control. Combined with his own understanding of this, the amazement on his face gradually turned into ecstasy, "It's incredible, this is a natural riverbed. Create a book, hurry up, come and take a look, it's really God wishes me the Tang Dynasty..."

Yan Liben also went downstairs with Luo Tong's help, and looked at him with a shocked look.

The geology here is hard, which is the most suitable place for opening rivers and the least suitable place for opening rivers.

When opening a river channel here, you will not worry about mud and sand, and it can ensure the quality of the Bian River water source, but because it is too hard, the difficulty of opening a river has exceeded the standards endured in this era.

But now God has solved the biggest problem for them. An earthquake actually shocked the natural riverbed.

"This is really a gift from God!"

Yan Liben also left this feeling.

"Hahaha……"

After being shocked, Li Yuanai couldn't help laughing loudly. In later generations, he had heard many new opportunities formed after major disasters such as crustal movement, diversion of the Yellow River, or earthquakes, floods, etc.

But I didn't expect that it would fall on my head today.

With this natural riverbed, most of the major project to lead Luo to Bian was completed before it was started.

"Let's go, let's go down the mountain!" Li Yuanai couldn't wait to go down for a field investigation.

The entire riverbed cuts the valley on the right side of Gubailing into two sections, and a slightly rugged and two-mile crack connects the valley. This natural riverbed goes directly to the vicinity of Rongze.

Li Yuanai had already understood the nearby water network and said, "We used this riverbed to guide Luoshui from Rongze to the Bian River, and everything would be fine." After a pause, he said, "After we went back, we immediately went to find Jiang Zhiming. Our ideas were inconsistent with him. He studied for many years and understood the situation better than us. First meet with him to discuss the details, and then apply for the river opening project to bring Luo to Bian. How much labor do you think you need to allocate?"

Yan Liben pondered for a moment: "This riverbed is properly utilized, and it is estimated that there are 100,000 people. In less than a year, the task will be completed."

This amount is almost the same as Li Yuanai's estimate. He originally planned to complete this matter in a long six or seven years, but now it only takes one year.

Only the gifts of nature can lead to this miracle.

Li Yuanai went to Guangwu Mountain and joined the guards.

At dusk that day, Li Yuanai arrived at the Bianzhou Wharf again.

The ship had not yet landed, and Liu Boying entered the warehouse to report: "Your Highness, Governor Pei seems to be waiting at the pier."

Seeing that he was not giving up, Li Yuanai said, "Please come on the boat."

The ship stopped steadily, and Lawyer Pei entered the cabin under the leadership of Liu Boying.

"I've met the King of Shang!" Lawyer Pei bowed and said hello.

Li Yuanai waved his hand and said, "I am wrong today. I originally planned to go to the Bian River to inspect it, but suddenly I had an idea and thought of a better way. The Bian River can transport for about two hundred days a year, and for the remaining 100 days, ordinary ships can still sail. Only a few cargo ships with heavy drafts are difficult to transport. In this case, there is no need to build a dam. As long as one tributary can be directed to transport into the Bian River and raise the level of the Bian River, it can ensure that the Bian River can transport throughout the year, which is very beneficial to the water transport."

He didn't give Lawyer Pei a chance to speak, and said, "Today, I and Doctor Yan personally investigated the terrain and have chosen the guidance route. Don't worry, I promise that in a year, Bianzhou will make great profits and become the center of the world's canal transportation."

Lawyer Pei is too utilitarian, and Li Yuanai doesn't like it, but he knows that he is a talented person and that Bianzhou is also rich under his governance. No matter what his purpose is, he is worthy of the people under his jurisdiction and has never thought about how to deal with him.
