Zhao Min successively sent two groups of water ghosts into the water to learn more about the specific situation of the shipwreck. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info Maybe the ship was washed away by the ocean current after sinking, and the shipwreck happened to be stuck in the depression of the submarine rock wall, and if you want to salvage the shipwreck, the first difficulty to overcome is how to make the shipwreck move out of the depression. As long as you translate out, things are easy to do, after all, it is a wooden hull, so it can't be no buoyancy at all, right?

Faced with a way to get the ship to translate on the seabed, everyone was at a loss. You can't let people pull it, right? Not to mention how long people can stay at the bottom of the sea in such bad weather, it's just that they can't borrow their strength in the water, and they can't even stand steadily, so how can they pull the wreck out? As for borrowing the power of the ship, it is even more nonsense, and it is not a submarine, how can the pull of the ship be horizontal and not longitudinal? You must know that there were no engines in this era, and the power of ships was all based on wind power or human paddles, and it was simply whimsical to want to tow a wreck out of it. Not to mention the need to overcome the angle difference between the seabed and the sea surface, how to prevent the stuck shipwreck from being blocked by the sunken top.

When everyone was at a loss, Zhao Min was writing and painting in the cabin. Just because someone else can't do it doesn't mean he can't do it. Just kidding, I am also a person who has studied the principles of mechanics, even if I have not studied mechanics, such a simple method can be imagined by modern elementary school students, at most it is just whether the estimate is accurate or not. Less leaning, the calculation has a result, Zhao Min confidently drilled out of the cabin and walked onto the deck, with a smile on his face: "Don't worry, this matter is easy to hear!" ”

Everyone was surprised, and they all gathered around to ask for advice, but Zhao Min just replied with a smile: "Don't be impatient, you'll see when the time comes!" After speaking, he turned his head and instructed left and right: "Zhongguo, you take two boats ashore and go to the nearest market to buy two hundred empty wooden barrels, which must be so big!" After speaking, he also gestured with his hand, "Buy some more big iron vertebrae and wheels, and a lot of ropes, the more the better!" After thinking about it, he added: "It's best to soak it in tung oil, and it will be stronger." ”

Zhang Han took the order and left, and everyone was confused. Empty barrels and ropes are easy to understand, and there are already floating barrel salvage methods in this era, which is not unusual, but what are iron vertebrae and wheels used for?

Zhao Min didn't have time to pay attention to them, and continued to explain: "Chenzhi, you take a red horse, hurry back to the water camp, and let them drive all the boats over!" ”

Xu Ming was taken aback, is this going to be forced? Pull the wreck out with all the boats paddling desperately? I couldn't help but hesitate a little at the moment: "Lord, do you want to bring all the hands of the water camp?" Why don't you go ashore and hire hundreds of fishermen to help? ”

Zhao Min knew that he had misunderstood as soon as he heard it: "No need, there are not too many people, just drive all the boats over!" ”

"Whoa!" Although he didn't understand very well, Xu Ming still took the order and left.

Zhao Min was proud. A proper sense of mystery is a good way to maintain the majesty of leadership, and this is a truth that he has long understood. If you all understand, brother is still a fart!

Zhao Min waved his hand vigorously: "All you have to do is to rest, maybe we will stay here for a few days!" ”

……

At noon the next day, Zhang Han was the first to return, and the two ships were full of wooden barrels. Zhao Min asked people to get a big iron spine and a wheel, and took a few long guns, and called a craftsman with the ship to demonstrate in the open space on the shore. He first passed the spear through the hole in the middle of the wheel, then placed two iron vertebrae on both ends of the spear, gestured with his hand, and asked the craftsman, "Like this, fixed to death, the length only needs to be slightly longer than the wheel; How long does it take to get four? ”

The craftsman thought about it for a moment, "Fixing it with a noose, rivets, and reinforcing it with brown silk is enough for two hours at most!" ”

Zhao Min nodded with satisfaction, encouraged the craftsman and asked him to hurry up and start work. The sea is not as good as the land, and it is all about the movement of ships; Ships can be damaged at any time in the event of storms, waves, battles, etc., so it is essential to repair the damage. Zhao Min silently muttered in his heart: "It's really convenient to have a craftsman!" In the future, will there be a rule that all the army must bring craftsmen with them? ”

In fact, this is just Zhao Min's own ignorance. Army craftsmen have been popular as early as the Spring and Autumn Period, and the daily construction of camps, equipment repair, and ordnance maintenance are indispensable for the presence of army craftsmen. It's just that Zhao Min is a high-ranking prince after all, and he has never participated in specific operations, so he doesn't know the truth.

An hour later, the craftsman reported that the reinforcement was completed, and Zhao Min personally led the team to the site that had been estimated a long time ago, and asked the water ghost to plunge the iron vertebrae down to the bottom of the sea, and repeatedly explained that it must be nailed to death, if it doesn't work once, twice, anyway, it must be firmly fixed on the bottom of the sea. At this time, Xu Ming also returned with all the ships in the water camp, Zhao Min counted, plus the original 35 ships, and immediately mobilized all the manpower to fill the empty ships with sand and gravel, and filled whatever was heavy, in order to achieve full load, and pressed the waterline of each ship deep into the sea.

When all the preparations were completed, it was already Shen Shi, Zhao Min called everyone to board the fully loaded ship, and staggered to the bottom of the sea, directly above the iron vertebrae, and at the same time tied all the empty barrels to the boulders and sank into the sea. After arriving at the predetermined location, arrange to divide all the ropes into four strands, one end through the seabed fixed reels and attach them to the wreck, and the other end to tie the barrel and the boat, and then tighten the ropes.

When everything was ready, Zhao Min gave an order, and everyone began to dump the sand and gravel and mud from the ship into the sea, while the water ghost cut off the boulder tied to the wooden barrel. As a result of the buoyancy of the barrel and the boat, the barrel and the boat exert tremendous upward force, and with the combined efforts of the two, the rope is stretched straight. And this huge vertical force turned into a horizontal force under the action of the 'pulley' on the bottom of the sea, pulling the wreck to creak. For a while, I saw the mud and sand rolling on the bottom of the sea, the turbidity overflowing, and the ropes on the ship also made an overwhelming gurgling sound.

Zhao Min stared at the sea nervously, although his calculations would not deviate too much, but there were too many uncontrollable factors, such as the degree of the shipwreck, such as the bearing capacity of the rope, etc., at this time he was also a little bottomless in his heart. As the ship's waterline rose inch by inch, Zhao Min's heart also rose to his throat. Suddenly, only to hear the sound of "boom", all the ships suddenly rushed upward, and even the bottom of several ships jumped off the water, and then fell back to the sea!

"It's done!" Zhao Min threw a fist excitedly, if this was not successful, his prestige would be damaged, not to mention, he could not afford to lose the time to prepare for salvage again! This is a special task worth 100 points, and if there is a mistake, I really can't imagine what the consequences will be. Fortunately, it was a one-time success, Zhao Min was overjoyed in his heart, and he wanted to shout two voices to express his excitement!

The cheers of everyone on the sea were one after another, and the eyes that looked at Zhao Min couldn't help but have a little reverence. The water camp was dominated by the original pirates, and most people's senses of Zhao Min only stayed in such a superficial impression that - oh, this is a prince, until this time at sea, the confidence shown by the King of the North Sea and the unheard-of salvage method completely shocked everyone, and people couldn't help but have a feeling that this is something that only a noble person with a destiny can want to do.

In the admiration of everyone, Zhao Min also slowly calmed down his excitement, smiled a little self-assuredly, turned his head to Xu Ming and said, "Chen Zhi, the follow-up here will be handed over to you." I'm a little tired, so I'm going to rest for a while. After speaking, he got up, and walked into the cabin like this, leaving only a deep and tranquil back for everyone.
