Neither more or less. Half a month later, the guards who went to Xianyang to deliver the letter returned. They accompanied them with Zhang Cang, Hu Kuan, Ma Gan, Gongshusheng and other familiar leaders and craftsmen from the Academy of Sciences. They also brought many large and small steel pulleys and even various tools, as well as two huge telescopes with a range of sight of more than twenty miles, which were loaded with several cars.

With Zhang Cang and his familiar subordinates, Chen Xu felt much more relaxed. He gathered a group of craftsmen in the shipyard, introduced each other and explained the sailing drawings again. He asked the craftsmen to lead Zhang Cang and others to observe carefully on the large ship with the bottom cabin and keel bones, and ordered everyone to cooperate closely and build the first sailing ship in human history as soon as possible.

Zhang Cang and others can understand the understanding of sails much more deeply than a group of craftsmen in Langya County. The craftsmen of the Academy of Sciences have long been experimenting with sails. Chen Xu mentioned in his letter to Zhang Cang. Therefore, this time there are several craftsmen who specialize in studying sails. The sails have been verified in the Wei River outside Xianyang City. They can indeed drive quickly by adjusting the angle of the sails, and they can even drive against the wind. However, the structure and production of the ship are more stringent. After all, if the design and production are unreasonable, it is easy to be blown over by light head and heavy feet.

Therefore, after a group of craftsmen who knew how to work as consultants, Zhang Cang quickly asked a sailboat designed in accordance with the drawings on the beach to plant three masts and start making sails. A few days later, sails of varying sizes on three sides rose, and a rudder of the same proportion was also made to cooperate with the sails. The sailing process on the sea was practiced in physical objects. At the same time, the iron smelter and the blacksmith shop were also prepared to start construction. The magistrate of Langya County mobilized tens of thousands of kilograms of steel and coal, and the difference was just customized on the spot.

"Two sets of moving pulleys, two sets of moving one, and hang side sails, which will save more effort..."

"The rudder rod needs two rivets, with an aperture of eight inches..."

"Twenty eight-inch round nails..."

"The diameter of the main sail winch needs to be increased by one foot..."

"The error between the steering wheel and the transmission gear is too large, and it still needs to be adjusted..."

"The bow rudder is not swinging strong enough, so it needs to be fixed with iron cables..."

"The rudder rod is not flexible enough, change to a pair of steel rings..."

A group of craftsmen and craftsmen from Xianyang cooperated with them, and the iron smelting furnaces and ironworks were jingling all day long. The craftsmen and craftsmen from Langya County were all stunned. They all looked like they had red eyes. They only saw the craftsmen and craftsmen from Langya County. They felt that they were all craftsmen, but the difference was no longer in the same era.

This is the difference between the craftsmanship and ordinary craftsmanship of the Academy of Sciences. Everything in the Academy of Sciences starts with experiments. Any innovative invention is first designed and drawn, then started to make experimental equipment, and finally continuously corrected the design and summarized the experience from the experiment. Although it is more costly, the effect is absolutely incomparable. Moreover, the Academy of Sciences is not afraid of spending money. With the support of two big financial supporters, Chen Xu and Emperor, all kinds of failures can be accepted, so it is naturally easier to produce results.

An ordinary riverboat worth five feet long costs three thousand yuan. The Academy of Sciences can build seven or eight ships in one go for repeated trials. Even ordinary wealthy businessmen cannot bear this amount, not to mention that such experiments may be scrapped once or twice.

In other words, all the success of the Academy of Sciences is actually made of money.

But Chen Xu was happy and helpless.

In any era, scientific invention and innovation are an extremely costly process. If countless money is spent, sometimes the results may not be seen.

However, for Chen Xu, the risk of invention and innovation is much smaller. The things he allocates funds to invent are basically things that have been familiar to later generations. Success is inevitable, but it also costs money and keeps spending money.

In mid-June, the two guards who went to Wancheng also returned, and more than twenty large trucks were accompanied by, all of which were loaded with muskets, cannons, gunpowder lead iron bullets and other items.

There were also a hundred young men who were training in Qinghe Town. More than a year later, these young men looked much taller and stronger, with uniform uniforms and steady manners, and the orders were obscured with a faint sense of military aura in later generations.

What surprised Chen Xu the most was that Wukong, who had gone out to look for a mother monkey since he returned to Xiaohe Village the winter of the previous year, actually came with him. He squatted in the carriage and looked around. After seeing Chen Xu, he screamed and jumped on Chen Xu's head and squatted down, grabbed Chen Xu's hair and scratched his head and was so excited that he was very excited.

Chen Xu was also very happy to see the monkey, so he gave him a big head and the monkey covered his head and tears came down.

Because the sailing boat was not built yet, Chen Xu personally led more than 100 teenagers to go to the old sea boat for training. After all, the bumpy sea is completely different from the land. Even without wind and waves, it can make people dizzy. What's more, a group of teenagers from the Central Plains who have never seen the sea before. Some people started vomiting after a few minutes on board. Chen Xu naturally experienced this feeling not long ago. He is still uncomfortable now, but it is much better, at least he won't vomit anymore.

The monkey was naturally excited and jumped up and down the big boat. He obviously liked this new toy very much. He was rushing around on the boat to make faces, which made a group of boatmen laugh. He liked this little thing very much and often threw some dried fish for snacks. The monkey quickly became a star on the boat.

Chen Xu didn't go far for the first time to go out to sea. He asked the boatman to put the boat five miles away from the coast, and then let the teenagers move on their own, familiar with the constant bumpy daily state of the sea. When he came back after two hours, almost except for the twenty teenagers who followed him, the other teenagers all vomited pale faces and couldn't get up. They felt that their heart, liver, spleen, lungs and kidneys were about to vomit completely.

But even though they vomited until they died, the teenagers gritted their teeth and persevered. The next day, they were on the boat and started training again. After two or three days, the situation improved greatly. Except for a few extremely serious and unacceptable people who were transferred to the warehouse to guard the gunpowder and guns, the rest began to load gunpowder on the sea boat for fire training.

The current muskets use shotguns and are not well sealed, so the effective shooting distance is only 100 meters. They are better than light crossbows but not as good as longbows. The only benefit is that as long as they learn to load ammunition, children aged seven or eight can become soldiers. This is the difference between hot weapons and cold weapons. A child can easily kill a young and powerful martial arts master with a hand gun.

Therefore, for Chen Xu, he does not need to recruit so-called rangers and young and strong adult men. He only needs to train a group of loyal teenagers well.

There were 200 muskets brought this time, as well as various supporting barrel machines, hammers and other accessories, with more than 3,000 gunpowder, more than 500 grenades, and eight cannons. These cannons were actually cast in steel barrels that set off fireworks. They were more than eight feet long, thin in front and thick in the back, with a hole diameter of six inches, and a pipe wall thickness of more than four inches. Each cannon weighs more than 800 kilograms. Three kilograms of gunpowder are consumed at one time. Solid iron bullets with a diameter of five.5 inches or shotguns with a diameter of half an inch can be used. As for the flowering bullets used by cannons, Chen Xu has not yet tested it, and there is no need at present. A solid iron bullet weighs seven or eight kilograms. When it hits a wooden boat at close range, it can explode a hole as big as a dustpan. It will be directly beaten into meat sauce. In this era, it is definitely a killer weapon. Nothing can be stopped. A large ship can be sunk in just a few cannons.

Since the start of training guns, the monkey was even more excited than Chen Xu. When he saw the boy training on the sea, he screamed excitedly and dragged out a musket and threw it in front of Chen Xu. Seeing that the situation was asking Chen Xu to install gunpowder for him, Chen Xu asked the boy laughed and cried. It turned out that when the monkey was in Qinghe Town, he often followed Chen Hu and a group of teenagers to train. When he was bored, a boy taught the monkey to fire a few times. Although he was beaten by the recoil of the musket every time, the monkey was happy.

So Chen Xu was curious and loaded gunpowder iron bullets on the hand gun and began to train monkeys to shoot the hand gun. After several trainings, the monkey actually learned how to do it. Although he could not install ammunition, he was already very skilled in firing. Therefore, every time a group of teenagers started training, the monkey would excitedly lift Chen Xu's gun holster.

After seven or eight days of adaptation training, the gun mounts on the large ship had been built. Chen Xu arranged for people to hoist two telescopes and eight cannons onto the large ship, and continued to go out to sea twenty miles away to train observation and artillery battles on the sea ship. At the same time, the training was also conducted on escape and lifesaving, and fishing boat control and other activities.

All training has only one purpose. Chen Xu must rescue Shui Qingrou without any mistakes. If Huangshi Gong dares to capture Shui Qingrou, he will chase him to Japan in one breath and kill Huangshi Gong and his disciples.
