Regarding Yang Wenhua's proposal, Yang Da was a little hesitant.

"If my brother prints all the secret methods of all walks of life into a book, and publishes them, although it can benefit the people of the Tang Dynasty, if it is easily learned by other countries, wouldn't it be very good?

Things are impermanent, the country is impermanent, if one day China is weakened, I am afraid that there will be a disaster of rivers and seas. ”

"Very good, it's really good that you can think like this, Yang Da, you have grown."

Yang Wenhua couldn't help but admire Yang Da's performance, and he was also a little puzzled in his heart, why did the cowardly teenager grow up so fast, and in less than a year, he gave people a sense of calculation.

Yang Wenhua didn't think much about it, maybe he was so genius.

"Don't worry, there will be fewer and fewer wars in Huaxia in the future, and before the surrounding small countries completely grow up, find a way to integrate them for the brotherhood.

And the brothers have always given them a shield instead of a spear, and even if they want to start a war, they will find that the defense is more than enough, and the attack is insufficient. ”

In the world, there is usually a spear before a shield, but Yang Wenhua did the opposite.

The technology of cement recipes and bamboo strip concrete, high-yielding seeds and all kinds of necessities of life was disseminated, but the gunpowder formula was clenched in his hands and not mentioned at all.

In this way, it is good that the city wall can be easily built very tall, and there are countless materials in the city, so it will naturally become much easier to defend the city, and the besieging party will have to work hard.

As for the aborigines who developed gunpowder themselves, let them take their time.

Gunpowder itself was already available in the Tang Dynasty, but it was just a mixture of saltpeter charcoal, and there was still a long way to go before the real gunpowder recipe went.

Even if Yang Wenhua had used explosives in the Battle of Goguryeo earlier and inspired them a little, it was not so easy to make real gunpowder, let alone gunpowder with a perfect formula.

All the big and small struggles in the world are for two reasons: one's own interests are damaged, or one can obtain benefits from others.

When people are not short of food and clothing, and the cost of war is too high and there is nothing to gain, naturally no one is willing to start a war.

"Since the elder brother has been thinking about it for a long time, the younger brother is too worried."

In the face of Yang Da's humility, Yang Wenhua said jokingly: "Think more, think more about things, people will become smarter." ”

Yang Wenhua and Yang Da talked, but the third sister rummaged through the boxes and cabinets in the room, and took out a small porcelain bowl out of the room, and asked Yang Da: "Big brother, is this what you fired here?" It's so beautiful, it's almost the same as what you use at home. ”

Yang Wenhua took the small bowl and looked at it, flicked it on the edge of the small bowl with his fingers, and suddenly made a crisp sound of gold and iron.

"Compared to the coarse porcelain at the beginning, it's really good."

Yang Da explained a little embarrassed: "According to my brother's secret recipe, the trial production has just been successful, and the cost is very large, but the finished product is not much. ”

"Take your time."

Yang Wenhua didn't say much, but comforted him.

At this time, someone outside came in to report to Yang Da, saying that the things were ready.

got the things he needed, Yang Wenhua didn't stay here for a long time, and took the third sister and Yang Da to the mill.

After replacing the large and small gears with the connection between the waterwheel and the mill, and replacing the stone mill with a wooden barrel, the thing was installed.

The big gear drives the pinion, and after several rounds of conversion, the speed of the pinion reaches a speed of tens of revolutions per second.

After connecting the accelerated pinion to the barrel, the iron pillar in the middle of the barrel is rotated.

When the chili pepper was put into the wooden barrel through the funnel, it was immediately torn into pieces by a dozen rotary knives on the iron pillar and spilled through the leaky net under the wooden barrel.

The vibration brought by the rotary knife can make a small piece of chili sink and a large piece or the whole chili pepper rise, as long as the size of the leaky eye on the leaky net is controlled, you can naturally get the desired chili sauce, and the thickness can be adjusted at will through the leaky eye.

Put 100 catties of chili peppers in it, and after three or two minutes, all of them will become chili sauce that is thinner than a fingernail.

The third sister cheered and shouted happily: "This is good, with this chili sauce, there will be no shortage of chili sauce again, and I won't sell chili peppers in the future, and I will sell them all after making them into bean paste." ”

Yang Da was also hot on the side, his brother was still his brother, and there were always so many incredible secret methods.

"Can such a barrel cutter be used to process wheat and grain?"

Yang Wenhua nodded, and said to Yang Da: "Theoretically, it is okay, just adjust it through the mesh below, when processing wheat, try to make the mesh thinner, and the position of the rotary knife should also be adjusted."

When used to process grains, you need to adjust the mesh to just allow the rice to come out, and the grain can't come out. ”

For these things, Yang Wenhua is difficult to take care of, there is originally a stone mill to use, Yang Wenhua feels that it is almost enough, if it is not for the third sister entanglement, this rotary knife will not be able to come out yet.

Yang Da nodded, "Brother, don't worry, such a sharp weapon, the younger brother will definitely send someone to study it well." ”

"Well, you can arrange it yourself, when printing books, the general technology is spread at will, and the high-end ones should keep some of it themselves, and it is still necessary to maintain a certain advantage."

Looking at the back of Yang Wenhua leaving with the third sister, Yang Daleng was a little distracted.

Who are you?

What do you want?

The little brother doesn't want to live up to you, it's just that everyone has their own chase, and it used to be difficult to survive, so naturally there was nothing to do, but now it's different.

Time is like flowing water, when the corn is blooming, the time has come to the beginning of August, every household in Guanzhong has planted a little corn, looking at the harvest is expected, the people are happy.

This year's catastrophe has finally passed, God bless, no one starved to death in such a natural disaster, and no one needs to live by selling their sons and daughters.

No, it's not the result of God's blessing, but the fact that Datang has produced a true immortal that allows everyone to survive this disaster year.

What a strange immortal, he doesn't need any sacrifices from people, and he can directly save the suffering.

Although I don't understand why, it's always a good thing to have such a god by your side.

The disaster year in Guanzhong passed smoothly.

And the military disaster in Liaodong is approaching step by step.

Although the god-like king is not in Yuanhua, his big-headed ghost army is still there, the laws he left behind are also there, and the various secret methods he left here are also there.

Especially with the existence of Sun Simiao's medical school, the Yuanhua people were not afraid of war, because the mortality rate of the Yuanhua War was not high.

If it weren't for the god-like king, Yuan Hua would not be allowed to expand by force, and Yuan Hua himself would have launched a foreign war.
