No more, no less, half a month later, the guards who went to Xianyang to deliver the letter returned, accompanied by a group of familiar leaders and craftsmen of the Academy of Sciences such as Zhang Cang, Hu Kuan, Ma Gong, Gong Yisheng, etc., and at the same time brought many large and small steel pulleys and even various tools, as well as two huge telescopes with a visual distance of more than 20 miles, which were full of several cars.

With Zhang Cang's group of familiar subordinates, Chen Xu's mood suddenly relaxed a lot, gathered a group of craftsmen in the shipyard, introduced each other, and then personally explained the sailing drawings again, and asked the craftsmen to lead Zhang Cang and others to the big ship that had built the bilge and keel to observe carefully, and instructed everyone to cooperate closely to build this first sailing ship in human history as soon as possible.

For the understanding of sails, Zhang Cang and others can understand much more profoundly than a group of craftsmen in Langya County, the craftsmen of the Academy of Sciences have long been testing sails, Chen Xu has mentioned in the letter to Zhang Cang, so this time there are a few craftsmen who specialize in sails, and the sails have been verified in the Wei River outside Xianyang City, and it is true that you can move quickly with the help of the wind by adjusting the angle of the sails, and even go against the wind, but the structure and production of the ship are more strict, after all, if the design and production are unreasonable, Being top-heavy can easily be blown over.

Therefore, after having a group of craftsmen who know how to sail as consultants, Zhang Cang soon asked people to plant three masts on the beach according to the size of the sailboat designed by the drawings and began to make sails, and a few days later, the sails of different sizes on three sides were raised, and a rudder of the same proportion was also made and the sails were matched, and the sails began to be practiced through the real thing.

"Two sets of movable pulleys, set two moving one, hang the side sail, which will be more labor-saving......"

"The rudder rod needs two rivets, and the aperture is eight inches ......."

"Twenty ...... of eight-inch round nails"

"The diameter of the mainsail winch should be increased by one foot ......"

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

"The bow sail rudder is not strong enough, so it should be fixed with iron cables......"

"The rudder rod is not flexible enough, and it is ...... to change to a steel live ring"

A group of craftsmen and craftsmen from Xianyang cooperated with the smooth flow, the iron-making furnace and the blacksmith workshop tinkled all day long, and the craftsmen who came and went were all like having pink eye, only a group of craftsmen and craftsmen from Langya County were all stunned, and they felt that they were all craftsmen, but the difference was no longer in the same era.

This is the difference between the craftsmen and ordinary craftsmen of the Academy of Sciences, everything in the Academy of Sciences starts with experiments, any innovative invention is to have ideas and drawings first, and then begin to make experimental equipment, and finally from the experiment to constantly revise the design and summarize the experience, although it costs more money, but the effect is absolutely not the same, not to mention that the Academy of Sciences is not afraid of spending money, with the support of Chen Xu and the emperor, the two big financiers, all kinds of failures are acceptable, so it is naturally easier to produce results.

An ordinary river boat five zhang long costs three thousand yuan, and the Academy of Sciences can build seven or eight boats in one breath for continuous trial and error, which even ordinary wealthy businessmen cannot afford, not to mention that this kind of experiment may be scrapped once or twice.

In other words, all the success of the Academy of Sciences is actually piled up with money.

But Chen Xu was tired of it, and he was helpless.

Scientific invention and innovation in any era is an extremely money-consuming process, and countless money is thrown down, and sometimes the results of the fart may not be seen.

However, at present, for Chen Xu, the risk of invention and innovation is much smaller, and the things he allocates funds to invent are basically things that future generations have long been familiar with, and success is inevitable, but it also costs money, and it costs money constantly.

In mid-June, the two guards who had gone to Wancheng also returned, accompanied by more than 20 carts, all loaded with gunners, gunpowder fuses, iron bullets and other items.

There were also a hundred teenagers who had been trained in Qinghe Town, and after more than a year, these teenagers all looked much taller and stronger, dressed uniformly and with steady demeanor, and the order and prohibition faintly had a bit of the atmosphere of the army of later generations.

And what surprised Chen Xu the most was that Wukong, who had gone out to find a female monkey since he returned to Xiaohe Village the winter before last, also followed, squatting on the carriage and looking around, after seeing Chen Xu, he squeaked excitedly and jumped on Chen Xu's head and squatted down, grabbed Chen Xu's hair, scratched his ears and cheeks, and was a mess of excitement.

And Chen Xu was also very happy to see the monkey, and rewarded him with a brain jump, and the monkey covered his head and tears came down.

Because the sailboat has not yet been built, Chen Xu personally led more than 100 teenagers to go to sea on the old sea ship to go to sea for training, after all, the bumpy sea is completely different from the land, even if there is no wind and waves, it can make people dizzy, not to mention a group of teenagers from the Central Plains who have never seen the sea, some people start to vomit within a few minutes of getting on the boat, this feeling Chen Xu naturally experienced not long ago, and it is still uncomfortable now, but it is much better, at least it will not vomit.

Naturally, the monkey jumped up and down on the big boat excitedly, obviously very fond of this new toy, and made faces everywhere on the boat, provoking a group of boatmen to laugh, and liked this little thing very much, and often threw him some dried fish as snacks, and the monkey soon became a star on the boat.

The first time Chen Xu went to sea, he didn't go far, that is, he asked the boatman to make the boat five miles away from the coast, and then let these teenagers move on their own, familiar with the daily state of the sea that is constantly turbulent, and when they came back after two hours, almost except for the twenty teenagers who came with him, the other teenagers all vomited one by one, their faces were pale and they couldn't get up, and they felt that their hearts, livers, spleen, lungs and kidneys were going to vomit clean.

But even if they vomited to death, these teenagers still gritted their teeth one by one, and the next day they went on the ship again with vain steps, and after two or three days, the situation changed greatly, except for a few extremely serious people who were transferred to the warehouse by Chen Xu to guard the gunpowder and firearms, the rest of the people all began to load gunpowder on the ship for gunpowder shooting training.

At present, the firearm uses a scattered bullet, and the seal is not good, so the effective shooting distance is only a hundred meters, more than a light crossbow but not as good as a longbow, the only advantage is that as long as you learn to load ammunition, seven or eight-year-old children can become warriors, this is the difference between hot weapons and cold weapons, a child with a handcuff, can easily kill a young and strong martial arts master.

Therefore, for Chen Xu, he doesn't need to recruit so-called rangers and young and strong adult men, he just needs to train a group of loyal teenagers.

There are 200 guns brought this time, as well as a variety of supporting barrel machines including hammers and other accessories, more than 3,000 catties of gunpowder, more than 500 grenades, and eight artillery pieces, these cannons are actually modeled after the steel cylinders that set off fireworks, the length is more than eight feet, the front is thin and the back is thick, the aperture is six inches, the thickness of the pipe wall is more than four inches, each cannon weighs more than 800 catties, and a loading needs to consume three catties of gunpowder, and you can use a solid iron bullet with a diameter of 5.5 inches or a scattered bullet with a diameter of half an inch. As for the flowering bullet used in the cannon, Chen Xu has not yet tested it, and it is not necessary at present, a solid iron bullet weighs seven or eight catties, and it can blow up a dustpan-sized hole in a wooden boat at close range, and it will directly turn into meat sauce when it hits the human body, it is definitely a big killer in this era, nothing can stop it, and a big ship can be sunk with a few cannons.

And since the beginning of training firearms, the monkey was even more excited than Chen Xu, seeing the teenager training on the sea, excitedly squeaked and screamed and dragged out a firearm and threw it in front of Chen Xu, seeing the situation was to ask Chen Xu to install gunpowder for him, Chen Xu asked the teenager with a smile, it turned out that when the monkey was in Qinghe Town, he often followed Chen Hu and a group of teenagers to train together, and when he was bored, there were teenagers who taught the monkey to shoot a few times, although each time he would be hit by the recoil of the firecracker, but the monkey was not tired of it.

So Chen Xu was curious to load the handcuff with gunpowder and iron bullets, and began to train the monkey to play the handcuff, after several trainings, the monkey actually learned well, although he could not install ammunition, but he was already able to shoot very skillfully, so every time a group of teenagers began to train, the monkey would be excited to lift Chen Xu's holster.

After seven or eight days of adaptation training, the gun carriage on the big ship has also been built, Chen Xu arranged for people to hoist two binoculars and eight cannons onto the big ship, and continue to go to sea 20 miles away to train the observation and artillery combat on the sea ship, and at the same time train escape and lifesaving, as well as control the fishing boat.

All training has only one purpose, Chen Xu must be foolproof to save Shui Gentle, if Huang Shigong dares to take Shui Gently away, he will chase to Japan in one go, and kill Huang Shigong and his apprentices and grandchildren.

It is necessary to use thunderous means to let all those with bad intentions know that against the disciples of the Immortal Family, there is only one way to die.
