Fan Wenhu, whose ancestral home is Shandong Road, is now the former deputy commander of the Great Song Army, in fact, he is also the son-in-law of Lu Wende, the envoy of Jinghu. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Of course, the Great Song Dynasty would send him to aid his father-in-law first.

He was indeed blocked by the Tatar army along the way, and they set up return cannons on the riverside, constantly smashing them with boulders------ but Fan Wenhu, the deputy commander of the palace, was not afraid of this, and their planes were not as tall as the head of Lin'an City!

He also had the means to fight back, and immediately ordered to fire artillery, shoot arquebuses!

All of a sudden, the two sides were fighting very fiercely!

The deputy commander of the palace will not hang out the commander's flag, won't that attract other people's blows? !

Anyway, at that time, the navy of the Great Song Dynasty also began to use a flag language that could express complete orders, which was very useful when sailing on the sea.

I heard that the Great Song Dynasty officials had inspiration, and then let the law be controlled and studied.

Some people say that this has been used on the island for a long time------ but these are not important, if you are equipped with a telescope, you can send messages far away!

He didn't let his ship participate in the counterattack, and ordered the others near the river to fight hard!

Soon, there were certain losses on both sides------ but his fleet was always heading towards Xiangyang, and after some time he was out of the range of the Tatars.

The Tatar return cannon couldn't adjust the angle for a while, but the artillery on their ship could, and Fan Wenhu, the deputy commander of the palace, wanted to order the warship to hit them again, because the opponent was no longer able to inflict damage on himself at this time.

However, as soon as he thought that his main responsibility was to support his father-in-law, he forgot it and left directly.

There were other obstacles along the way, but they were far less powerful than before, and there were even Tatar troops who were stepping up the construction of return artillery.

Fan Wenhu, the deputy commander of the palace, observed the Tatar army on the shore with a monocular, and he pouted and thought, "Fools are fighting land battles with you, and I only hate that this Han water is not wide enough------ before, his father-in-law had already written to him and told him about the whole battle situation.

Why do we have to fight with you on land? You came to attack the city------ I have 20 years of military reserves, the waterway is unblocked, you have a kind of go up to the river to bite me, probably this is the idea.

When they arrived at the cement slab bridge, they were happy to see that it was just right for a ready-made pier.

At this time, he heard a sharp whistle, and it turned out to be on the high platform, and the soldiers with bed crossbows and artillery waved at them!

Whoever defends the city hopes that there will be supporters, which is a psychological need.

------------------------------------------------------------

To tell the truth, Zhang Guoan and Wang Defa were proud of their ability to teach the science and technology of the Great Song Dynasty------ because they saw that even the people had learned to use counterweight stone cannons!

Of course, this is not an armament used for war, but they learned to use counterweight levers to make well tools, to carry water, and some private commercial docks also put on small counterweight booms to lower the goods!

At this time, the Great Song Dynasty was also an eclectic period that could take the initiative to absorb the essence of foreign culture!

If it weren't for Zhang Guoan's island lord and them taking the initiative to take out the counterweight stone cannon, then the Tatar return cannon would be the top killing weapon in this time and space.

The Great Song Dynasty had stone throwers a long time ago, and the reason why they were far from returning to the science of artillery was very simple, because their stone throwers only relied on hundreds of people to pull together, so as to catapult out more than ten kilograms of "boulders".

This completely relies on manpower to work together------ because it is impossible to make hundreds of people at the same time, so the launch orbit is never consistent, and the power of people is always limited, so their catapults are mostly used to scare people.

Fortunately, there are only a dozen people in the counterweight stone cannon, and the original artificial pulling force is converted into a vertical lifting force, as long as the lead block of the counterweight is pulled up vertically, and it can be fired directly with its gravity.

Needless to say, the benefits are there.

In the real history, on the principle of mechanics at this level, on the transformation of force at this level, the Great Song Dynasty was defeated!

In a few years, 60 million Han people in the south were slaughtered!

Let 100,000 elites commit suicide by jumping into the sea and accompany a dynasty to perish together------

Who can say that barbarism is a civilization that is defeated only by ignorance and brute force??

That only shows that the degree of civilization is not enough!

When Zhang Guoan, the owner of Liuqiu Island, and Wang Defa, heard that the folk of the Great Song Dynasty had counterweight water poles, and there were also counterweight booms on the wharf, the two decided to drink some wine at night.

I'm really happy, the Tatars still regard the return cannon as the highest military secret, and the common people of the Great Song Dynasty have seen it and used this technology.

As long as any technology can be developed to make it practical for the common people, this technology will continue to develop, and there will be anything with higher technical content.

The wisdom of the people is infinite, but you have to give them a foundation, or a fulcrum.

Zhang Guoan, the owner of the island, drank a glass of beer in one sip, which was specially fermented for them quietly, and then picked up a fifteen-centimeter-long tomato juice shrimp by sea, sweet and sour, delicious.

He wiped his hands, then drew a match from the porcelain bottle, swiped it on the rough surface of the mouth, and lit the pipe.

The wife's quietly fermented tobacco is also really good, with a smell of red wine.

Zhang Guoan, the island owner, sighed comfortably and said: "This nation is like this, if you give a little sunshine, it will be brilliant, have you read the "Principle of Leverage" written by that law?" ”

Wang Defa nodded, and also drank a cup of coconut wine, feeling that this degree can be fifty degrees, which is a bit of a coconut fragrance------ fruit liquor is not the higher the degree, the better.

He said: "The content is simpler------ but in terms of leverage, he has at least become a small system, not fragmented, especially when he gives examples, the examples used are concise and practical!"

This is important! ”

Zhang Guoan, the owner of the island, smiled and said: "I know, as soon as you look at my books, you will understand my vision------ this nation has a deep culture, but it is always fragmented development, let's help them build a system or platform, if they don't get it right, they will automatically supplement and participate in the construction."

You think, when I was a child, I used to use a counterweight lifting pole to draw well water! ”

Wang Defa said: "I also used it when I was a child------ you are right, this saves us a lot of things, we are interesting enough for the Great Song Dynasty, you see they like to use quantitative relations and spatial forms to express problems, it is hard to say whether they can invent analytic geometry in a few decades!" ”

Zhang Guoan, the owner of the island, immediately said: "No, no, decades are too long, we still have to use this principle ourselves------ but unfortunately the first batch of houseboys are not talented in mathematics, look at the second batch." ”

Take your time, everything will be okay as long as we are still there.

Both of them were a little proud of their contribution to the progress of science in the Great Song Dynasty.

It is really refreshing to be able to secretly promote the development of a nation on the side------ they have already seen through fame and profit, and those really meaningless efforts make people have a little expectation to see the results!

However, soon their pride turned to anger! (To be continued.) )
