The exploration of the ancient well in the Han Dynasty was still relatively smooth, from the very beginning, only Gu Xiaoliu went down, and then there were other tiger guards to replace, and in the end Xiao Ming couldn't help but go down, judging from the information provided by the people in front, Xiao Ming has mastered the general situation in the secret passage under the well, and it is indeed as they described, that it is really like a canal underneath.

For the ancient canal, Xiao Ming only knows a Zhengguo canal, which is still a canal in the Warring States Period, no one knows what it looks like, according to the description in the book, it is probably a water storage and drainage project, but the secret canal in front of him is a drainage canal specially hit on the cave wall.

The water flows through the trough above the excavated stone wall and is poured into the well, but there is not much water in the spring itself, which is the well, so the well has to rely entirely on the flow of water from the aqueduct to supply water, which is why the well sometimes has water and sometimes has no water.

The canal is built entirely on the topography, since this is the case, there must be a water source, along the direction of the secret passage water flow we quickly found the water source, less than two miles away from the distance of the road, this secret passage to the tail, that is, the beginning of the "Pinghuai waterway".

The space here is very large, and all of them are artificially excavated, the waterways extend in all directions here, there are many branch tunnels, stretching in different directions, Xiao Ming counted that there are as many as thirty-nine, in addition to the secret passage that comes in, there are another thirty-eight channels of water flow, and the local water diversion structure as a water source can not be found or seen at all.

Xiao Ming went back to tell Ding Jianpeng about the situation underground, and drew a basic appearance on the ground, including the more than 30 waterways, this way of building water channels underground, no one has ever seen it.

Ding Jianpeng carefully looked at the graphics that Xiao Ming drew for him, compared the distance and direction, and finally said: "The direction of this water source is in the direction of Jiaogang Lake, if you don't guess wrong, that water source should be Jiaogang Lake!" ”

Now it seems that if you want to explore all the secrets here, it will definitely take a lot of time, Xiao Ming immediately sent people, quickly returned to the iron factory to call people, and sent another hundred tiger guards over, to shorten the time, it is necessary to send more people, and at the same time, he also asked people to buy water trucks from other places and villages with water, and use ox carts to pull a few carts of drinking water first, and first solve the drinking water difficulties of the people here in Jiang Village.

The time dragged on for a day, Gu Xiaoliu and a few of them went down to explore the secret passage to report that the thirty-eight water channels had also been explored, and a huge copper gate was found in the waterway, in fact, it should be said that it was a copper gate, a total of thirty-eight copper gates, and it looked very heavy.

Xiao Ming is a little anxious now, Liang Xiaowang's golden treasure has not been obtained, and now there is an underground water conservancy hub in the Han Dynasty, he seems to be a little unable to get out, he told Ding Jianpeng about it, and wanted to take Ding Jianpeng to explore Jiaogang Lake first, but Ding Jianpeng said that he was not in a hurry, let himself think about it again.

On the morning of the third day, Xiao Ming was woken up, he is now temporarily living in the villager's house, and someone came to report that a stone tablet was found in the secret passage, and asked Xiao Ming to go and watch, this time Ding Jianpeng followed Xiao Ming down to the secret passage, and he couldn't help but be amazed at the water conservancy project carved in the stone passage in front of him in the Han Dynasty.

The stele was found in a stone chamber, which is the water source below Jiaogang Lake, the stone chamber is very hidden, two meters high from the ground, and now it has been made of wooden planks to form a staircase, when Xiao Ming and Ding Jianpeng stood in front of the stele, they couldn't help but be surprised by the words on the stele!

There are eight big characters on it: "Heaven sets up a thunder pool, and the water cannot be discharged"!

"Is this the ultimate secret of the treasure?"

Xiao Ming really couldn't believe it, was this the treasure that Antao had worked so hard to? The layout of this water area Ding Jianpeng gave a very high evaluation, through this period of investigation found that the length of this secret passage is very long, basically connected to the Huanghuai River basin of the lakes as many as three, through the difference in topography, the lake waters of the whole region are regulated, irrigation is carried out in this way during drought, drainage is carried out when waterlogged, and the key role lies in the 38 copper gates.

Ding Jianpeng ran almost all over the secret passage, and the conclusion of the investigation was amazing! The copper door can be opened and closed by a button, but the button has been ineffective for a long time, which is why this underground water channel has not functioned all these years.

"How does it work?" Xiao Ming asked.

"Through that well! If I'm not wrong, there should be more than one Han Dynasty well like this, and we will definitely find it if we look everywhere," Ding Jianpeng said.

In the next few days, the tiger guard of the Taiping Iron Works has arrived, under the command of Ding Jianpeng, and the investigation of the entire Jiaogang Lake and the surrounding waters has begun, Xiao Ming took the time to go back to the iron factory, he has to deal with some things, and the 200,000 horses of miscellaneous silk have arrived in Xuzhou by ship, and the next step is to send someone to contact.

The quality of this miscellaneous silk is not bad, it is more suitable for military clothing and other things, Xiao Ming sent someone to inform Xue Bingchang in Tokyo, and immediately organized transportation to Liao, and the name of the caravan was used to set several names within their Yaxing Gang, which were all negotiated, and the tokens provided by Xiao Zhonggong at the border could be directly transported to Shangjing in Liao.

At the same time, Xiao Ming personally wrote a letter to Xiao Zhonggong, claiming that the miscellaneous silk arrived in Liao in three times, and asked him to send someone to accept it, and at the same time expressed his longing, hoping that there would be a chance for the two to meet again and talk happily......

Two days later, Hangzhou Su Caier had information that the flying kite came, asking Xiao Ming to go back to Hangzhou nearby, Richanglong may make internal rights adjustments, this time is the best opportunity for Xiao Ming to become the owner of Richanglong, let him go back early.

Xiao Ming thought about it, and felt that he should indeed go back, it has been almost half a year since he left Hangzhou, this time he is going to take Ding Jianpeng to set up a scientific research base in Hangzhou, no matter what happens to the gold, after this time, he will leave immediately, but I don't know what happened to Ding Jianpeng?

Just thinking about it, his subordinates reported that Ding Jianpeng was back!

The first thing he said when he saw Xiao Ming, Ding Jianpeng said: "The gold has been found!" ”

"What?" Xiao Ming was shocked.

Ding Jianpeng was not in a hurry, it was fine, he poured himself a cup of tea, sat down easily, looked at Xiao Ming's anxious appearance, he smiled slightly: "Don't worry, listen to me tell you slowly"

It turned out that Ding Jianpeng spent a lot of energy to study the underground water canal project during this time, on the one hand, he admired the whimsical ideas of the ancients, and on the other hand, pondered the specific working principle of the entire water canal, and finally discovered that the role of the entire water canal was the key to ensuring that the entire upper reaches of the Huanghuai River would not be flooded.

Since ancient times, the Yellow River Basin and the Huaihe River Basin are frequent flood areas, and here is the core area of the Central Plains, for many years, the authorities are committed to solving this eternal problem, but have not found a good solution, but the ancients still have great ingenuity and extraordinary perseverance, the invention of this underground water canal is actually a good solution, although its scale is smaller.

In fact, in the Song Dynasty, the Chinese have a high utilization method for water conservancy and river channels, according to the "History of the Song Dynasty" records: during the Renzong period, Huainan transshipment made Qiao Weiyue responsible for the management of the Huai River, the creation of the Erdoumen, is a canal lock in the form of a double lock, thereby improving the river transportation capacity, the invention of this double lock belongs to the world's first, in the "Mengxi Pen Talk" has a detailed record.

Shen Kuo also described the application effect of this technology, and during the Tiansheng period, after the Zhenzhou section of the Yangtze River (now Yizheng, Jiangsu) was reopened, saving 500 workers and 1.2 million yuan per year. In the past, ships could only carry 300 stone of grain, but after the lock was built, ships with 400 stone of grain could pass.

This area of the underground water canal belongs to the south bank of the Huai River, there are many lakes, from the current exploration results, the coverage of the canal includes Jiaogang Lake, Wabu Lake, Gaotang Lake and other lakes, and the wells found along the way have reached more than 80, but most of them have been abandoned and damaged, and Ding Jianpeng told Xiao Ming that the canal has not been repaired, but only a half-finished product, as for why it has not been repaired, Ding Jianpeng judged that it may be the rise of the groundwater level and the fracture of the rock layer underneath......

"And ...... are you talking about gold?" Xiao Ming is most concerned about the key to the matter.

Ding Jianpeng said: "Do you remember the thirty-eight 10,000-pound bronze doors? Seeing Xiao Ming's puzzled eyes, Ding Jianpeng continued: "That's gold!" I estimated that each copper door is about 8,000 kilograms, and all of them add up to a total of 618,000 catties, which is only a lot more than 600,000 catties! ”

"You said the bronze door was made of gold?" After seeing Ding Jianpeng's affirmative eyes, Xiao Ming was stunned, but then he was overjoyed, this gold has appeared now, and how to get it is the key.

But Ding Jianpeng poured cold water on him again: "The gold must have been transported from the lake into the secret passage, which means that the outlet is in the lake, but this outlet seems to have been blocked, if you want to get the gold, you must drain the lake, once the lake is discharged, the canal will be invalid, and it may cause a large-scale flood!" ”

Xiao Ming was surprised: "But now it's a big drought!" ”

"It's a lot of work! You'll have to build a cistern and then export the lake before you can take the gold, and it's a shame that the canal is now useless, even though it's lost! Ding Jianpeng said very regretfully.

Xiao Ming laughed, we use the most modern water conservancy knowledge to build a modern reservoir here for flood control, irrigation, breeding, etc., isn't it much more practical than the abandoned canal? “

"That's what you said!"

Xiao Ming said: "This King Liang Xiao is very strange! Why spend so much money on such a huge underground pool? ”

Ding Jianpeng said to Xiao Ming: "Think about it, the fief of King Xiao of the Han Dynasty is in the Liang State, and his project is mainly aimed at the north shore of Huanghuai, in addition to Jiaogang Lake, including Tianjing Lake, Tuohu Lake, Wabu Lake, Gaotang Lake, Nushan Lake, Huayuan Lake and other lakes, once who plays a role, can ensure that the entire Liang fief for at least a few hundred years of wind and rain, become the richest area, this is his purpose." ”

In any case, Liang Xiaowang's starting point is good, but such a huge project is bound to cause a lot of casualties, and the people are innumerable, and it is difficult to comment on the merits.

The next work is easy to do, neither of them is a water conservancy professional, but they can draw sketches based on the terrain, there is cement in the iron factory, as long as there are drawings, you can use concrete to build dams and reservoirs, although the cost is a bit huge, but there are more than 600,000 catties of gold as the bottom, there is nothing to be afraid of.

Moreover, at this time, two talents arrived one after another, the first of which was the Jewish genius: Acheli! Xiao Ming was very happy about his arrival, and now the problem of the gap in funds can finally be solved!
