Barrage refers to intercepting water, which is also the main function of the dam, so the dam is also called the barrage.

Although Huang Yueying was in charge of the construction of the dam for the first time, she knew Li Bing's deeds and had some research on how to build the barrage.

Huang Yueying took the craftsmen on the Mekong River on a military boat for three days, and had a draft on how to build the dam on the river, but Huang Yueying then thought that there were some difficulties in repairing the dam, but the first need for too much cement, with the daily output of cement in Wanghai and Linjiang cities now, it is far from meeting the needs of building the dam, not to mention that a lot of cement is needed to build the road, so Huang Yueying and An Zhongzhi discussed, the dam was temporarily shelved, and Huang Yueying drummed up the bridge, which is also the task of Lin Bei. And this is more urgent than building a dam.

As the route to the upper reaches of the Mekong River becomes longer, the tributaries of the Mekong River become more numerous, and some small rivers do not need to build bridges, because they can be cut off directly, such as the small river with a width of about 10 meters, but the tributaries of the Mekong River can be far more than this kind of small river, and some of the tributaries are quite many rivers with a width of 30 or 40 meters, and even more than 100 meters wide, which requires a bridge to be built quickly to ensure the smooth flow of the route.

On this day, Huang Yueying and some stonemasons rushed to a place more than 800 miles upstream of Linjiang City, and the military boat turned into a tributary of the Mekong River, which has a very strange name, called Yijiang.

The river is quite wide, and the water flows into the Mekong River from the west, which just blocks the direction of the road, and the sergeants have already explored it by boat, and there is no particularly narrow river within 50 miles of the river. Therefore, Huang Yueying and the craftsmen came to prepare to survey the topography of the river, and then came up with ideas to build a bridge as much as possible, so as not to delay too much time.

"How wide is this river?" Stand at the bow of the boat. Huang Yueying asked.

"The narrower place is more than 30 zhang, the width is more than 50 zhang, and the water depth is more than 10 zhang." The sergeant on the side said.

Hearing this number, Huang Yueying did not speak, the craftsmen were already discussing, in fact, many craftsmen are no strangers to building bridges, some stonemasons or carpenters have more or less built bridges, although they are all small bridges. But the erection of the small bridge and the principle of the bridge are the same, and the role is the same.

"The water depth is only more than ten zhang, we can first make a few cement bridge piers, put them down in turn, and the bridge will be built on them."

Huang Yueying asked: "How to erect the bridge piers?" Although the water depth is only more than ten zhang, who can go down? I don't even know what is going on at the bottom of the river, so what shape should be made under the piers? Otherwise, if it is uneven, the bridge will collapse. ”

"It's better to make the piers pointy. Piercing the bottom of the river? ”

"The stones at the bottom of the river are strong, and this method is not feasible." Huang Yueying frowned. When even if it was vetoed.

"Lord Huang, the narrow part of this river is only more than 30 zhang wide, why not only erect bridge piers on both sides? How about crossing the deepest part of the middle of the river with the method of arch bridge? ”

"As you said, the river is no more than thirty feet wide. If this river needs to be arched, then what if we want to build a bridge in the Mekong River in the future? Can the arch bridge cross hundreds of feet? So I had to think of a way to erect a bridge pier at the deepest part of the river. ”

This time, Huang Yueying and the craftsmen returned in vain, and Wanjiang West Road could not be repaired. However, fortunately, Wanjiang East Road has not encountered a big river like a river for the time being, but the news that the sergeants have probed back is not very good, in front of Wanjiang East Road a hundred miles, there is also a big river, although this river is slightly narrower than a river, but it is definitely necessary to build a bridge.

At this time, Lin Bei, who was on Fountain Island, suddenly opened his eyes, and he woke up.

At first, he was a little confused, but when he smelled the sea breeze, Lin Bei woke up.

"I'm asleep after molting, it looks like I'm hibernating again, but why isn't it too hot, isn't it April yet?" Lin Bei remembered what he had experienced before sleep, the torture before molting, then growing in size, then successfully molting, and finally falling into a deep sleep from exhaustion.

"My lord? Are you awake, sir? A sergeant shouted in surprise from the side.

Lin Bei followed the prestige, and saw that there were many sergeants holding swords and arrows within dozens of zhang around him, obviously protecting his safety, Lin Bei smiled and said: "Well, wake up, hard work." ”

The sergeants knelt down and shouted, "I'm waiting to congratulate you on getting one step closer to the dragon." ”

Lin Bei can only hehe, turn into a dragon? He wasn't so arrogant, "Get up, it's April?" ”

"It's mid-February." A soldier replied respectfully.

He woke up in mid-February? Does this mean that his hibernation period is now shortened? It is estimated that the body is stronger so that it will be like this, Lin Bei didn't bother to think about it anyway, so he said: "In this way, let's go back to Haicheng first, right?" ”

"No, by the way, my lord, General Cui Lan is in the sea."

"Oh? Is it and blackheads? ”

"Exactly."

"Then it is estimated that I won't be able to find her for a while, so let's leave one person behind, and when Cui Lan comes back, I will tell her that Lord Ben is looking back at the sea."

"No."

Lin Bei got up and found that the snake scales he molted were still on the side, and they were stacked, Lin Bei inexplicably felt a little pain, and his tail slapped and smashed the snake scales, because as soon as he saw the snake scales, he remembered the unbearable memories of the past few days, which was really painful.

Twisting his body, hearing the sound of clicking in the bones, Lin Bei felt so cool, this is a healthy body, with this movement, Lin Bei found that his body had become a little different.

Needless to say, the body is longer and bigger, first of all, Lin Bei's strength, Lin Bei feels that his strength should be greatly improved, as for how much he has improved, Lin Bei can't be sure, but at least it should be more than doubled, in the past, Lin Bei may have about 20,000 catties of strength if he used all his strength, but now he should have 40,000 catties of strength.

In addition to the obvious increase in strength, another kind of improvement is not so obvious, because this is Lin Bei's feeling improvement, when Lin Bei used to perceive the surrounding situation with all his might, the radius of the perception range was almost five miles, and now this range should be expanded, and it is clearer, as for how to make it clear, Lin Bei is not easy to describe, can only give an example, if it was SD image quality when it was perceived before, then now it has to be high-definition image quality.

"The potential of this body is really strong, every time it molts, it can make great progress, if it can really evolve into a Jiao, then it should be such a potential, but it's very strange, Haka is only more than thirty meters after turning into a Jiao, and he is now thirty meters, why hasn't he turned into a Jiao?"

For this doubt, Lin Bei obviously couldn't answer it, and then, Lin Bei's heart moved, and he touched the horn of Haka in the box placed on the side with his tail, and found that the breath of Haka was a little lighter, of course, it was not that the breath of Haka horn dissipated, but that Lin Bei was stronger, so the effect of Haka horn on Lin Bei became smaller.

"I'm about the same size as Haka, and I'm still going to be affected, it seems that this is not a difference in size, but a gap in strength, no wonder that guy launched a frenzy to kill so many natives, I'm afraid I can only fight this breath if I really evolve into a Jiao."

When you are ignorant, you can be fearless, on the contrary, the more you know, the more awe-inspiring, Lin Bei is more and more curious about why Haka can become a Jiao.

While thinking about it, Lin Bei took the sergeant to the outskirts of Fountain Island, and got to the beach to take a boat.

Now the sentry tower has also been set up on Fountain Island, which is located near the beach, and when he saw Lin Bei coming, the sergeant in the sentry tower was stunned at first, and then hurriedly saluted.

Lin Bei nodded at them, and then saw the big boat parked near the beach, Lin Bei was a little surprised, and then said happily: "The big boat has been made?" ”

The sergeant hurriedly replied: "Yes, my lord, the length of today's big ship is ten zhang eight, and it was just made by Huang Sikong. ”

"Eighteen zhang? Compared with the previous seven-zhang big ship, it is eleven zhang long, and Yueying is really good. Lin Bei laughed.

Eighteen zhang big ships can be regarded as big ships even in modern times, at least civilian ships can rarely exceed this length, and in this era this kind of big ship can be described as a giant, but it is estimated that it can only be used at sea, if you want to travel on inland rivers, small rivers can not turn.

"My lord, this is still a double steamship, and its speed is a little faster than that of the previous steamboats, and now it can sail eighty miles per hour."

Lin Bei smiled even more happily, Huang Yueying really didn't disappoint him, not to mention improving the big ship, but also ingeniously installed a double steam engine on the ship, even Lin Bei himself didn't expect it, it can be seen that Huang Yueying is not only very talented, but also very open-minded, and this is the best quality of a good scientific researcher.

"Get on the boat and set off to look back at Haicheng." Lin Beida laughed and got on the boat first, and the sergeants followed.

Such a big ship already has a trace of aircraft carrier posture, when sailing at sea, when encountering big fish is not afraid at all, but the big fish will take the initiative to avoid, and the safety has been greatly improved, unless it is encountered in big waves or windy weather, otherwise the probability of an accident on this kind of ship is very small.

It took two and a half hours for the big ship to arrive at Wanghai, and before the ship docked, the sergeant on the pier had already seen Lin Bei's huge body coiled in the bow of the ship.

"Your Excellency is back!!"

"Lord Ryujin is back!!"

"Meet the Ryujin-sama!!"

This return, Lin Bei found that the sergeant was quite enthusiastic, of course, he was also very enthusiastic before, but this time he was obviously more fanatical than before, Lin Bei was a little confused, and said in his heart that he had just lived on Fountain Island for a while? When the fishermen pass by Fountain Island, they often go up to Fountain Island to kowtow, so it shouldn't be like this, but I wonder why there are many people pouring out of the long street, and they have heard the news and come to see him, and the road is almost blocked.

"It's exactly the same as when I went back to the village after hibernation last year." Lin Bei was a little speechless, but this year Lin Bei was finally more accustomed to such a scene, and after getting off the boat, he walked through the crowd and was very calm. (To be continued......)
