The flow rate increases and the pressure decreases.

This is the famous Tang Dynasty "Zhang Caozhi Effect", which is common knowledge for anyone who has studied physics.

In fact, when Lao Zhang did the force analysis, the shipwrights couldn't understand it at all, but it didn't matter, because in the end, Lao Zhang himself couldn't understand it.

Shipbuilding or something, Lao Tzu knows how to make an egg, and the reducer is much easier to get than a ship. It can be seen that the operation of the machine is far more promising than the operation of the ship.

"Alas, if Lao Tzu can build a flying clipper, it will take this effort."

Throwing the charcoal pen in his hand, what a crosssail and what a tailwind and a headwind, it just hurts so much that you don't want it. The sand boat uses a hard sail, which is convenient and easy to build to save money. But that's not what Lao Zhang wants.

For Zhang De, one day his fleet arrives in the Americas, tsk, peppers, pumpkins, peanuts, grass and mud horses, which can solve a lot of things.

At least eat boiled fish, and don't soak the dogwood yourself to make it spicy.

Moreover, in the current climate and environment of Bashu Jingxiang, if there are chili peppers to dispel dampness and sweat, it will definitely improve the spirit of the people fighting heaven and earth.

Again, sometimes I get tired of eating tofu brain, and I want to taste the spicy taste. Of course, the sweet tofu brain fed Xue Zhaonu this bun face, and she doesn't eat it now......

After all, he had been fighting at sea back then, and although his main job was to pat the leaders of liberal arts students, this did not prevent Lao Zhang from knowing that the current in the Tsushima Strait was the lowest in February. For example, he didn't remember any monsoons, Kuroshio, or South China Sea currents.

So in the end, it was the ship that had to be solved.

I knew that I was going to cross, what kind of machinery and what materials he learned at the beginning, and directly studied ship engineering. But basically, if you study ship engineering. There should be no work to be found in the Tang Dynasty.

"For the chili peppers!"

As soon as he thought of chopping pepper fish heads and boiled fish, Zhang De cheered up again. Continue drawing. In any case, big ships can't be built. Let's try the water in a small boat first.

Because the old man Wang Xiaotong made a big news in Youzhou, for the sake of the open-pit coal mine, Zhang Gongjin, the governor of the Dingxiang Governor's Mansion, used the public weapon for private use, and asked his subordinates to surround the open-pit coal mine, and then jointly with Youzhou to carry out military exercises.

In short, it sounds very good in name, and it will deter the suspicious separatists in the center of the Khitan tribes.

Uncle Zhang is not stupid, the black is a stone? That's money! That's Kaiyuan Tongbao! That's his heart! That's his second Princess Langya!

The army can't do business, but the local people in Youzhou can. When the time comes, the coal is dug up and crushed to make briquettes. Add a zero and sell it to the barbarians for cattle and sheep, how cool and scientific.

However, when Uncle Zhang was working hard, the eldest grandson Chong, the son of the Duke of Qi who was addicted to making money, actually came to pay New Year's greetings to Zhang De in the first month, which was too enthusiastic!

"! ! ”

The eldest grandson, who has been in Cangzhou for three days, has a light in his eyes, "Brother Wei has already contacted Hou Xuanchen, hurry up and prepare a batch of goods, Yingzhou has already taken care of my brother." When the time comes, something will happen, and a guard will come out and confess. As a brother, he has long said yes. If it happens, I will confess his guilt, and my wife is young, and I will raise her by myself. ”

Ouch. Actually, you are not the eldest grandson Boshu, but the eldest grandson Mengde, right?

Lao Zhang was stunned, and his eldest cousin didn't know what was crazy, so he suddenly went from Chang'an to Hebei with three horses a day. Then he told Lao Zhang that he was going to fight, and he was going to fight. Let's hurry up and stock up, and then the Hebei Provincial Grain Transit Envoy will be in the seat. It must work......

In fact, Zhang De knows very well that it is not realistic to fight Goguryeo in the past two years. The political situation is quite stable now. The border pass is also building the Great Wall, and the border governor has fought from the Turkic Xue Yantuo to the Khitan Xi Department in the past few years. Fighting wars every year, who can stand it.

Man is not a machine, he can be tireless and not afraid of death.

Again, in the past few years, His Majesty the Emperor has been known to be wise and martial, and the treatment of veterans is very high. Even loyal patriots like Wang Zuxian are specially concealed in the Fuwei Dart Bureau to engage in civilian security work.

Those who are in a hurry to do Goguryeo, except for the loveless guy like Yu Chi Lao Mo, there is only Su Dingfang, who wants to be promoted and make a fortune and wants to go crazy.

Even Li Jing and Li Tao have only one thought at present, the emperor said that I will do whatever I do, and everything will follow Li Dong.

"Brother Boshu, it's not a matter of importance, why do you need to do this?"

The eldest grandson Chong suddenly looked surprised: ", you are full of gold and silver, I don't know how difficult it is to be a brother." Adults go to the year, alas...... Do not say. ”

It's all tears when you talk too much, because Du Ruhui didn't die, and because the old devil did the capital of Anbei, the eldest grandson Wuji wanted to stretch out his hand in the court, which really increased the difficulty factor a lot.

Although the younger brothers still support the eldest grandson mountain, but now Wei Chi Shantou Fang Du Shantou looks very powerful. The prostitute in Pingkangfang changes to a green building and a red hall is called job hopping, and the younger brother changes the boss, in fact, it is not a big deal.

Although he will be sprayed as politically immature, he will be regarded as a villain. However, the county officials are not as good as the current management, the emperor has not given the eldest grandson Wuji a benefit for a long time, and their little brothers are very anxious.

"Uh......"

Last year, Zhang De grew a little taller, and the whole person was thicker again, plus he often engaged in machines, although the two arms were not pure unicorn arms, it was obvious that it was no problem to slap Qu Tuquan to death.

"The batch of white sugar that went out of Hedong is not a net profit......"

"Alas! This is to subsidize the family, what is this? The eldest grandson frowned bitterly, "All the rooms of the eldest grandson's family have to move to Chang'an, and those who eat idle meals don't know how many." If you reject people thousands of miles away, you will be judged by adults, and I am afraid that it will plummet immediately. His Majesty was originally going to let the adults recover, but somehow, Du Gong was actually healthy, and now he is participating in political affairs, and he is still at the court meeting, and he has drawn up a matter. Alas......"

In short, your eldest grandson's family pretended to show family harmony, and then the seven aunts and eight aunts took care of the eating, drinking, and Lazar, right?

Who is to blame for this? The cannon you have made an appointment with, no matter how difficult it is, you have to fight it. If your eldest grandson's family loses the reputation of family harmony, just rely on Li Dong to support you, believe it or not, don't want Wei Chigong to make a move, Wen Yanbo alone can make you ********.

The eldest grandson complained about his grievances, and Zhang De made him a pot of tea, and the two drank together, which was very harmonious.

However, after spitting sour water for a long time, the eldest cousin suddenly took out a letter from his arms and handed it to Zhang De: ", this is a letter from your cousin." ”

Burst!

"Ahem, ahem......"

Lao Zhang almost choked to death on the spot, it was too sudden! It was so unexpected! This Nima has no warning, and the high-energy reaction does not prompt a few meanings!

The tiger's body was shocked, and Zhang De's hands trembled a little: "Watch...... Brother Boshu, this ...... It's not appropriate. ”

"Lizhi is devoted to you, and as a brother, there is only so much she can do. Alas...... Nowadays, there is no way to find someone who can marry Lizhi. ”

Blame me?!

Zhang De still doesn't want to accept the letter, this is a pit. Also, what do you think in your heart when you send your sister as a cousin? The color of the head is black, not green.

"This, Brother Boshu, His Royal Highness Changle is of unparalleled appearance, and he must have a good person who can be a concubine."

"You're a good man."

The eldest grandson Chong looked regretful, "If you become a colt, it will be invincible to cooperate with you for your brother." The Zhang family is rich, the eldest grandson has the power, and he has his back to the heavenly family, just ask the vast earth, who is worthy of the opponent in the world......"

This is a little familiar.

"The younger brother has a marriage match, Huzhou, and the younger brother loves it very much. Let Her Royal Highness the princess fall in love wrong......"

"Why do you like young girls?"

Lao Tzu doesn't like young girls! Lao Tzu is just engaged! Lao Tzu will wait for her to grow up slowly!

“……”

Zhang De did not defend himself, so he silently took the letter from Changsun Chong's hand. What's the matter? Cousin pimping his cousin? Is the object a former rival? Ouch, this plot is in line with the construction of spiritual civilization.

It can't be blamed that Changsun Chong has become so strange, it can only be said that he has tasted the sweetness. His father is so powerful, but he used to rely on talent, which is simply the most stupid behavior.

Since his father is powerful and powerful, of course he is turning his power into cash. Talent, can talent be eaten?

Besides, his own talent was crumbling after being beaten by a group of bear children in Qujiangchi. In this regard, Changsun Chong has only one thought: to ****** talent!

", after this batch of silk has passed Yingzhou, there will be a western black clumsy of Goguryeo to connect. You can rest assured that they are all your own people. ”

After a pause, Changsun Chong lowered his voice and said, "Isn't it because you want to buy the Baekje people and the Silla people?" Is it a lack of labor? Rest assured, there are reliable people in Yingzhou for my brother. The clumsiness of Goguryeo happened to have a group of Nanmurwei people at hand, all of whom were arrested in November last year, and there were seven or eight thousand. ”

“……”

Cousin, how did you end up like this? What's wrong with this society? Shouldn't an outstanding young man like you read poetry and books and then find Confucius to make mock papers for three years, and then take the Jinshi exam to reach the pinnacle of life?

Look at Senior Brother Sun Fujia, he did a good job in Dali Temple. The messenger of justice is the nemesis of crime, and the people are very supportive.

Seeing that his cousin had become so inconsistent with the traditional education of feudal etiquette, Zhang De couldn't help but sigh in his heart: Such an incorruptible and shameless young man, Lao Tzu will have more! (To be continued.) )
