On February 14th, the fourth month of Chongning in the fourth year of Emperor Huizong of Song Dynasty, the Si hour was four times, and the modern hour was 10:58 am.

Yue Fei felt that the biggest challenge was to let the people in front of him understand and accept common sense that children in later generations knew.

He knew that the manufacturing industry in the Northern Song Dynasty was the best in the world, and the things they made were flocking to Gentiles.

The court and businessmen of the Northern Song Dynasty already knew to keep the secret. This was the origin of the official salt and iron ban and the salt and iron embargo.

However, even the advanced level of manufacturing in the Northern Song Dynasty only involves a few kittens and puppies, which are far different in both quantity and depth.

In other words, even the apparent geographical advantages are far from being exerted.

However, those parties did not realize this, and even felt that they had reached their peak and satisfied the existing things.

If this consciousness predominates, it is obvious that the quiet thoroughfare will stop moving forward.

The research project proposed by Yue Fei does not cover everything, but is full of their ideological confinement and knows that there is heaven beyond heaven.

After opening the gap, users of these new projects will broaden their horizons and put forward new requirements to prompt the inventors to develop new projects in order to meet their needs.

By continuously expanding new fields in this way, new products can emerge, establish a new order, and improve production efficiency.

"Such multi-functional spear will become a standard weapon in Chenggang Village and Wuligang Town. There will be more demand in the future, with a huge number, and at least 100,000 shots. This is a key link in improving productivity and the combat effectiveness of villagers and being able to protect themselves, so it is very urgent.

“I hope you can complete this task in two to three months and then put it into mass production.

"You don't have to worry about production, we have some special responsibility.

Li Chun asked curiously: "Xiaofei, you mentioned just now that multifunctional spear can also improve productivity? What's going on?"

Yue Fei explained: "Multifunctional spears have the functions of iron shovels and iron picks. Because of the excellent materials, both of them are more efficient than existing agricultural tools iron shovels and iron picks, and their productivity is correspondingly improved. Of course, they are used for those who use these two types of agricultural tools.

"There is another reason, because of this special tool, I can combine farm work with training.

"This can take into account the needs of both, so as not to affect training, and not to affect training, and to use both hands and kill two birds with one stone."

Yang Tai was fascinated by hearing this: "Xiaofei, you are so awesome! This is my dream of uncle. It's just awesome to take into account both."

Yue Fei said: "Let me go back and send a new spear to Uncle Yang to see if I can use it to show off some sets of Yang's marksmanship."

"That's great! I'm looking forward to your Uncle Yang."

Yue Fei ended the discussion on multi-functional spear and continued to mention a few cutting-edge weapons. Multi-functional spear is just a low-end mass product.

If you make such things well, you can generally improve the people's level.

However, only cutting-edge weapons can break through the deadlock and make the overall level leap, whether at the strategic level or tactical level.

"I'll mention something more below. You haven't seen it or even heard of it. Even something you can't imagine.

"First, high-end warships, also include high-end civilian ships.

"Didn't we mention the development of water transportation before? We have Tanghe River nearby and the Yellow River is not far away, so we must use it.

"This utilization includes agriculture, industry, commerce, transportation and other civilian applications, as well as military applications.

"The most basic thing about this military application is self-defense ability. Otherwise, what we work hard to produce will be taken away by the enemy, wouldn't it be a wedding dress for others?

"Self-defense is the lowest-level military application; we can't just wait for the enemy to come to bully us, right?

"The next step is to hit the enemy's door with teeth. Since they can come, we can go. Of course, this requires a more powerful ship.

"This level of counterattack is probably not far away, but it cannot be ruled out that you need to cross the ocean. Even if you are far away, you will be punished.

"This is not something that ordinary big ships can meet the needs, a huge ship of ten thousand tons, imagine it.

"It is probably as high as the highest point of our Wuligang, and it is half the length and two widths.

"If we build a giant ship building, it must be at least 100 floors high to meet the needs of researching parts.

"In fact, even building medium-sized ships, even small boats, requires a combination of many functions.

"You probably know that after this Tang River, you will enter the Wei River. You can enter the East China Sea through the Wei River. You can enter the vast ocean through the East China Sea. Then you can sail to the vast ocean surface. The shore is the land and people you don't know.

“Since there are those strange places, shouldn’t you be familiar with it?

“If that place is good, shouldn’t you consider taking it for yourself?

"Without violating the principles of nature, what's wrong with you taking the initiative to expand the scope of influence of civilization?

"We can't always wait for others to come to bully us, so we can't take the initiative.

"However, the premise is that we have those big ships and corresponding weapons and equipment.

"Only take action when you are ready, otherwise you will be sending someone's head."

Speaking of ships and weapons, Yang Tai is most interested in it, and he is half an expert.

Others are either not interested or even though they are interested, they know nothing about it, and they are watching flowers in the fog.

When Yang Tai heard the vision described by Yue Fei, he couldn't help but get excited. The sails on the sea were like pegasus on land, which was refreshing.

"Xiaofei, uncle, I have something unknown. If the big ship I mentioned meets the enemy at sea, will it be a battle with guns and knives?

"Even if you use a bow and arrow, it is probably difficult to break the defense, right? Do you use a siege crossbow, or change your name, an attack ship crossbow?"

Yue Fei secretly praised in his heart, Uncle Yang is indeed worthy of being behind me, and he can see this step. Even if he doesn't hit it, it's not far away.

"Uncle Yang is a good problem! Uncle Yang's direction is right, but it is more powerful than attacking ship crossbows, and it is about a thousand times more powerful.

"The main weapon of ship-to-ship is the cannon, which is powerful. If you hit a key part, you can sink a 10,000-ton giant ship with one shot.

"But the artillery fire was not that powerful at the beginning. Conventional weapons were ship-mounted guns and heavy machine guns, and the main targets of attack were people.

"After we build this behemoth, we will compare and study the real thing, and now we have a concept first.

"Another function of these ships is the ship's ability to attack land.

"For example, we have one, and the enemy is not that developed yet, so we arrive directly at their shore cities or ports.

"In this way, we need to have a ability to destroy the enemy without getting off the ship, at least disarming them and not threatening us anymore.

"At this time, a weapon is needed to suppress the resistance on the shore and can attack the enemy in depth.

"This is a special kind of cannon that can adjust the range and firepower intensity as needed.

"At that time, Uncle Yang took such a large ship and led a fleet of thousands of large ships, all equipped with new cannons, so he could travel as he pleased and traveled freely, and the world could go everywhere."

Yang Tai laughed: "That's great! I must go to every place!"

Yue Fei took the opportunity to explain to Cheng Yi: "Now Grandpa Cheng depends on you! You see, the most difficult problem you have solved has been solved. Uncle Yang voluntarily drove a new type of warship to sail for a long voyage. This is usually hard to find. After all, going to sea is a waste of life. In the future, you need someone like you need, just look for Uncle Yang directly. Uncle Yang, that's what you mean, and you will set sail from Tanghe."

When Yang Tai heard Yue Fei's big bag, he wondered, did I have that meaning? Did I say that I did not consider life and death and experiment with a new ship? When did I express that you are looking for me at any time? Am I a person who is not afraid of death?

However, I really have the ambition to show my power across the world, after all, I am a descendant of the Yang family!

I did express this just now, although it was made to make Yue Fei's child look like another.

Forget it, at this time, people must be timid and not timid.

"Okay! Come to me."

There are examples of floating on the sea, and another area is flying in the sky.

Yue Fei knew that when people in the Northern Song Dynasty mentioned flying in the air, they were all in their minds of Taoist people who ascended to become immortals in the sun. There was probably one around them, Taoist Master Chen Tuan, a legendary powerful man who flew to the sky and escaped the earth and was close to the earth. There was no problem with ascending to the sun.

However, the flight that Yue Fei mentioned is something that everyone can do, let’s not talk about nonsense.

Therefore, he must give them the source of the truth, otherwise people who are full of immortal and illusory control will never be able to create practical aircraft.

In order to explain this issue, Yue Fei also put a lot of effort into it.

He took out a tanned urine bubble that had been removed from the fishy smell, blew it round, and then tied it tightly to keep it bulging.

Using the reserved section on the thread that tied the urine blister, hang a subtle little doll puppet on it, and then let go.

Although the urine bubble was not very buoyant, the little doll was very light and still easily brought it up and rose slowly.

When Yue Fei had a physical model, he immediately felt that it was much easier for him to explain the principles of the aircraft.

"When it comes to flying, it is difficult for ordinary people to ascend to the sky, because people are not birds.

"Actually, if you really understand why birds can fly, there is no mystery.

"Man is the spirit of all things. It is easy to talk about it, but when you encounter a real situation, you forget it. For example, the stupidest old hens can fly, and you take it for granted that you can't fly for granted. It's so stupid.

"Did you see that puppet? Can anyone with eyes see it?

"But you didn't expect that even puppets could fly, why do you think you can't fly?

"That's a word, you're worse than puppets.

"Now, through this little playful, I learned from one example and let you understand the principles of building an aircraft.

"I will remind you that learning from one example and another is the ability of human beings and also the characteristics of human beings. You must have this ability.

"But not, make up for it quickly, otherwise there is no difference between it and a pig.

"This puppet can fly entirely by the lifting function of this urine blister.

“Where does this lifting function come from? It’s because there is air inside the urine bubble.

"You can't see the air, but it does exist.

"If you are careful, you will see me blowing the puff of the puff of the puff of the puff of the puff of the puff of the puff of the puff of the puff of the puff of the puff of the puff of the puff of the puff of the puff.
