After Yang Qiu received the order, he immediately took action and went to gather people to prepare the materials that needed to be used. He was accompanied by representatives of other ships who had come to the meeting. These representatives must learn Yang Qiu's methods in the shortest possible time, and then return to their own warships to draw gourds and teach the soldiers of their own ships.

In order to avoid startling the grass and snakes, and to ensure that all the Soochow "water ghosts" are left, the final action must be carried out by six warships together, so the time is urgent. The main waste of time lies in the spread of knowledge and the process of rowing back to their ships by representatives of the remaining five warships.

The time to actually use it for underwater ** transformation is actually very short, because this kind of transformation is so easy. To build an underwater**, you first need a sealed container. There are a lot of bottles and cans on the ship, but there are not many that can be effectively sealed, after all, this is not the era of screw caps flying all over the sky in later generations.

Yang Qiu skipped the stage of rummaging around the ship for sealed containers, and immediately decided to use ** to transform it directly. There are a lot of ** reserves on the ship, some are large and some are small, the small ones are as big as winter melons, which can hold more than ten catties of fire ~ medicine, the big ones are the size of wine barrels, and they can hold dozens of catties of fire ~ medicine, and even a small number of super-large models can hold hundreds of catties of fire ~ medicine.

The reason why Yang Qiu chose ** to transform is mainly to consider the problem of sealing. If the seal is not good, as soon as you throw it into the water, the lead will be wet with water, so what is the use? **The lids are threaded, and then padded with several layers of waterproof tarpaulin, as long as the lid is tightened, it can ensure that the river water can not wet the fire ~ medicine and the lead in the slightest.

The method of transformation is very simple, first pour out all the fire ~ medicine inside, then weigh out two catties and put it back, and then fill in some iron sand to increase the weight of the underwater **, to ensure that the ** can sink when thrown into the water, and finally cut the lead wire to the required length to complete.

It's easy to say, but there are still some tricks, for example, the length of the lead wire is carefully calculated by Yang Qiu, which can ensure that the underwater ** sinks to the appropriate depth and detonates. Yang Qiu asked every two soldiers to be in a group, responsible for fiddling ~ making an underwater **, the two of them worked together, and the whole transformation process only took one or two minutes.

However, Yang Qiu's calculation and demonstration process took a few minutes longer. What is complicated is the calculation process, and after the calculation is completed, the subsequent work can be understood at a glance, so Yang Qiu only demonstrated it once, and the soldiers around him and the representatives of the other ships learned it.

After the representatives of the other ships learned, they immediately brought the parameters calculated by Yang Qiu (fire ~ drug amount, lead length, iron sand weight, etc.), returned to their own ships as quickly as possible, and then organized personnel to implement the plan.

Although everyone has tried to lighten their steps and speak softly, there are still some people in the "water ghosts" of Soochow at the bottom of the boat who notice the abnormality. These are experienced old "water ghosts".

Although they sensed that something was wrong on the ship, they could not retreat without permission, and could only report the situation to the captain while they were floating to breathe. At first, the captain refused to retreat, after all, this was almost the last chance for the Soochow naval army. If they can't scuttle these super battleships tonight, who knows if they will break through Soochow's defense line tomorrow.

Although this defense line is strong, it seems to be almost an insoluble existence to the people of Eastern Wu, but since Guan Gong dares to attack, it means that he must have a way to break through it. How could a person like Guan Gong, who had fought all his life, fight an uncertain battle, he must have planned and then acted, and he must have thought of a way to clear the reef.

If the reef at the bottom of this section of the river is cleared, the entire Yangtze River waterway will no longer be in danger to defend, and the Jingzhou Navy can go straight down the river to build a business, and the destruction of the Wu State is imminent. It was with this in mind that the generals of the Soochow Navy had this in mind, so they had tonight's action.

They realized that danger was coming, so they were so eager to carry out this plan tonight, even planning to prevent twelve enemy warships from seeing the sun tomorrow at all costs. That's why the captain is not willing to give up easily.

He was given the order to scuttle the enemy's super-battleship even at the expense of all the "water ghosts". Without these super warships, the strength of the Jingzhou Navy has dropped by half. At that time, even if the reef is cleared, in the face of the Jingzhou naval army, which has suffered a great loss in strength, the Dongwu naval army will be able to resist one or two.

However, as more and more old "water ghosts" reported to him that there was an abnormality on the ship, the captain gradually became calm. He is not afraid of sacrifice, but he can't let these "water ghosts" sacrifice in vain. These are the essence of the Soochow Naval Army, and it is very difficult to cultivate.

If these enemy ships could be scuttled and discovered, they would have been discovered, but the current situation is that the enemy ships are still impregnable, and although there are reports that some debris can be chiseled off, such a small debris is still far from being chiseled.

In other words, if you don't retreat now, it is likely that these water ghosts will be sacrificed in vain. After much deliberation, the captain made a difficult decision and ordered everyone to be gathered and prepare to retreat. Unfortunately, his order was given too late.

A lot of Jingzhou Navy soldiers suddenly appeared on the sides of the six cement warships, which made the captain's pupils dilated not far away in the dark, and he was finally sure that his people had really been discovered.

He didn't notice that among these Jingzhou sailors standing densely on the side of the city, there were two different people every about five meters. These two people who are different from each other are the soldiers who were in charge of modifying the underwater ** just now.

The two men are now holding a watermelon-sized underwater **, and the other is holding a torch and waiting for the battle. The two soldiers formed a bombing team and were tasked with throwing underwater **, while the other soldiers standing around them were armed with bows and arrows, ready to beat the water dogs.

Under the coordination of the light signal, the bombing teams of the six battleships acted together, and the soldiers armed with torches quickly lit the fuse, and then tightened the lid of the underwater **. After he had done all this, the soldier who was holding the underwater ** hurriedly threw ** out of the side of the boat, and ** fell into the water in a free fall movement about one or two meters away from the hull.

All of this was planned in advance, and when Yang Qiu calculated the length of the leads, he had already calculated the time required for them to point the leads, twist the lid, throw **, and other actions. The soldiers were also told that these maneuvers must be performed strictly at this speed, otherwise their lives would be in danger.

Fortunately, these soldiers are highly trained people, they are accustomed to obeying orders, and they are clean and clean at completing these movements, and there is absolutely no mud and water. As a result, these underwater ** were successfully sealed and put into the water on time.

At this time, the captain of the "water ghost" team of Soochow had already blown the bamboo whistle in his mouth. Special forces like them, who carry out secret missions at night, have a requirement to be silent throughout the operation, not to mention blowing a bamboo whistle, and even if they speak, they must keep their voices as low as possible. Now blowing the piercing bamboo whistle so uncharacteristically, there is only one possibility: our whereabouts have been exposed~ exposed, and all of us urgently retreat.
