"But how are we going to cooperate with the snake then? Or how to cooperate with the king's shopkeeper? ”

Tang Ping looked at Lao Cui Lao Du with a sad face, and he couldn't help the smile on the corner of his mouth.

Lao Cui and Lao Du were also holding back their laughter, and they could only say that this shopkeeper Wang thought very well, and found someone to drug the wine in the new hotel in Tangping, so that the reputation of the new restaurant could be ruined.

But the problem is that Tang Ping's wine is different from the wine in their restaurant or the entire Chang'an.

The wine in this era is all found in a large vat, and the guests have to drink as much as they want, to put it bluntly, they are all bulk wine, but what Tang Ping is going to sell at that time is all bottled wine.

There are a lot of wine bottles, not to mention the ancients, even modern people have not drunk it, and it is difficult to open it normally without brute force.

And when the time comes, he plans to sell bottle by bottle, how do you call the snake the medicine?

"Forget it, anyway, now he's looking for a snake to do things, and then we'll see the tricks, this thing is evidence anyway, and he won't be allowed to deny it when the time comes."

People in this era would never have thought of such a thing as a camera recording, so they were not prepared for it.

The decoration of the restaurant has been done, and today Tang Ping brought a lot of decorative crafts that he bought from modern times.

There are also a lot of gadgets that emit light with batteries, and he believes that these things here will definitely shock many people who see them for the first time.

August 15 was the auspicious day that Li Yuanji told Tang Ping, and Tang Ping also thought it was a good day, so he chose to open on this day.

Early in the morning, the crackling firecrackers startled the people around them.

You must know that in the Tang Dynasty, although everyone also set off firecrackers, it was really bamboo, that is, the bamboo was used to burn, and then the sound of popping, so it was called firecrackers.

and the 10,000 rings used by Tang Ping, it is very different.

Li Shimin stood on the highest fourth floor, looked at the crackling firecrackers below, and suddenly asked, "Tang Ping, why is this thing so loud?" ”

"Back to General Li, this kind of firecracker, in fact, has a small amount of gunpowder in it, and after these gunpowder are ignited, they will release heat and a large amount of gas sharply, and the pressure inside the firecracker will increase instantly, so it will explode."

After thinking about it, he explained in simpler words: "It's like filling too much gas into a very small space in a very short period of time, and then it's full." ”

Li Shimin nodded as if he didn't understand, and the people around him also stretched out their heads and looked at the firecrackers below.

Only Li Tai took a notebook and took notes carefully, and after listening to Tang Ping's explanation, he suddenly asked: "Curator, if you make this firecracker bigger, put more gunpowder inside, and replace the paper wrapped on the outside with iron, will it become more powerful?" ”

Tang Ping didn't expect him to ask such a question, and he was a little stunned for a while.

Firecrackers were originally the prototype of thermal weapons, and many later thermal weapons were developed in this way.

It's just that he didn't expect Li Tai to see firecrackers for the first time, and after hearing his explanation, he would be able to associate so much.

And this is not over, Li Tai, who is usually cold, is slowly getting excited at this time.

You must know that now in the new school hall, they have learned a lot of mechanical knowledge, so he diverged his thinking and asked: "Then if we control the direction of the explosion again, let the driving force of the explosion ...... in one direction."

"By the way, when the bow and arrow are fired, am I because I am forced? If we use this power to push the bow and arrow, wouldn't it be possible to increase the speed of the bow and arrow. ”

"The curator said that the higher the speed of movement of an object with the same mass, the greater its kinetic energy, then it means that the power of the bow and arrow will become stronger!"

At this time, Li Tai's eyes were glowing.

Tang Ping couldn't be tied up, this Li Tai usually only thinks that he learns everything quickly, but he didn't expect that he has reached such a point?

Although he only thought of using the propulsion of the explosion to propel the arrow instead of the bullet due to the limitations of his knowledge, the principle was almost the same as that of activating a bullet.

And the earliest muskets, wasn't it just stuffed with gunpowder, and then put a projectile on it, igniting the gunpowder to later activate the projectile?

Li Shimin also became interested and asked Li Tai: "How strong can the power become?" ”

Li Tai shook his head: "I don't know, I won't know until I have specific experiments." ”

Li Shimin turned his head again and asked Tang Ping: "What Qingque said, is it possible?" ”

Tang Ping nodded first, and then shook his head: "It is indeed possible, but it is not to stimulate the bow and arrow, but something else!" ”

"Something else?"

"Yes, for example, a projectile made of iron."

"Where's the power?" Li Shimin continued to ask.

Tang Ping hesitated for a moment before saying, "If you succeed, you can break through the Chang'an City Gate a few hundred steps away." ”

The fourth floor of Xihe Building, which was still a little noisy, suddenly became quiet.

Cheng Zhijie, who was standing beside Li Shimin, shouted directly: "Tang boy, do you know what you are talking about?" ”

Wei Chi Jingde also said with an incredulous expression: "Break through the Chang'an City Gate a few hundred steps away? How is this possible? ”

However, Li Jing, the god of the Tang Dynasty, said with some distraction: "If you have this sharp weapon, wouldn't it be easy to conquer the city?" ”

Tang Ping hesitated when he said it just now, because he felt that such a weapon of war should be brought into this world by himself.

But for a moment, he gave up hesitation.

Because the longer you stay in this era, the more you can understand the cruelty of this era.

Now in the entire Tang Dynasty, except for Dongyue, which is in the honeymoon period, other countries are eyeing the hinterland of the Central Plains.

It can be smoked at any time, and this is an era when if you don't fight out, you will be beaten in.

Instead of this, Tang Ping of course still stands on the side of the people of the Tang Dynasty.

Rather than let the Turks, Tibetans or Western barbarians launch a war to attack the Tang Dynasty and make the people of the Tang Dynasty suffer, then it is better for the Tang Dynasty to attack it.

At this time, it was originally the opening ceremony of the restaurant, but none of the people on the fourth floor were still thinking about it, and they all looked at Tang Ping.

Tang Ping looked at the others, then approached Li Jing and asked, "General Li, are all the adults here credible?" ”

Li Jing first glanced at Li Shimin, and then looked at the other people who came today, it can be said that this is all Li Shimin's most trusted courtiers, so he nodded and replied: "You can believe it!" ”

Li Jing is the first celebrity Tang Ping met here, and he also knows his status in the Tang Dynasty and history, so naturally he said that it is credible, then there should be no problem.

"Guys, I can do an experiment for you."
