"Tian Lei? That's called gunpowder!" When Li Xiu heard that Li Shimin was like others, he thought that Dong'an Casino was struck by sky thunder, he couldn't help but smile proudly. Gunpowder is definitely one of the greatest inventions of mankind, but unfortunately it is often killed by mankind.

"Gunpowder? What is that?" Li Shimin obviously first heard of this term, and his thick eyebrows were also frowning.

"The definition of gunpowder is a bit complicated to explain. We can be more intuitive. I heard that King Qin is brave enough to be a member of the three armies, but I am just a weak person. It can be said that it does not pose any threat to King Qin. This is also the reason why King Qin dares to see me alone. But if I say that I can kill King Qin in an instant, I wonder if you believe King Qin?" Li Xiu smiled again. I am afraid that only he dares to say that he killed Li Shimin at this time.

"I don't believe it!" Li Shimin shook his head almost without hesitation. On the one hand, he had confidence in his own force, and on the other hand, as Li Xiu himself said, he was just a weak scholar, and he might not even be able to beat the most ordinary soldier on the battlefield.

"I knew you didn't believe it." Li Xiu said suddenly and reached into his sleeve. This was also when he came to the Tang Dynasty. It turned out that the ancients used to put things in their sleeves. They usually had a pocket in their sleeves. This was also one of the reasons why the ancients' sleeves were so wide.

The weather is cold now, and Li Xiu was wearing very thick clothes. When he came in just now, Li Shimin didn't even ask someone to search him, so he quickly took out a pottery jar from his sleeve. The two fists were of very small openings, and were tightly plugged by a block of wood, and a piece of fuses stretched out from the block.

"Please take it first, I'll go to the greenhouse to get something!" Li Xiu stuffed the pot into Li Shimin's hand, and then entered a greenhouse without saying a word. Although the people from the Ministry of Agriculture were emptied, the greenhouse inside was still running normally. In fact, Li Shimin also knew the importance of the corn in the greenhouse, so he not only did not destroy the Ministry of Agriculture, but also sent heavy troops to guard it.

Li Xiu came to the fire stove in the greenhouse, opened the lid and clamped out a piece of red coal with tongs, and then walked out again. Li Shimin was looking at the pottery jar in his hand. When he saw him coming out, he asked with a puzzled look: "What is this?"

"Haha, your highness, don't worry, I'll demonstrate it to you and you will know!" Li Xiu smiled strangely when he said this, and stretched out his tongs and ignited the fuse of the clay pot in Li Shimin's hand. As a result, the fuse immediately flammed with sparks, which scared Li Shimin, but he did not throw away the clay pot. After all, for those who have never seen the power of gunpowder, it is impossible for him to feel danger.

Li Xiu watched the fuse burning all the way, and he did not rush to take the pottery jar. Until the fuse was about to burn, he suddenly reached out to grab the pottery jar, then threw it out, and pulled Li Shimin to hide behind the greenhouse. Li Shimin, who was unknown, had no idea what was going to happen next?

As a result, as soon as the thrown pot fell to the ground, it made a loud "boom" sound, soil and debris flew around, and the smoke filled the air and could not see the situation there clearly. Li Shimin was completely shocked at this time.

As the explosion sounded, the guards outside rushed in in panic. When they saw the smoke and dust in the yard, the soldiers who ran in did not know what to react for a while.

"It's okay, let's go down!" At this moment, Li Shimin finally reacted and waved his hand to let the soldiers coming in retreat. The leading general immediately agreed, and then he led everyone out again.

"This is the power of gunpowder!" Li Xiu looked at Li Shimin with a smile at this moment, but he found that the other party's face was very bad and seemed a little annoyed, but this was normal. After all, the jar was in his hands just now, and Li Xiu did not remind him of the power of this jar. If Li Xiu had not thrown the jar out at the last moment, the consequences would probably be unimaginable now.

However, although Li Shimin was annoyed, he was even more curious about the power of this gunpowder. He did not speak at the moment, but walked to the explosion. This place was originally the farmland of the official office, and the ground was very soft, but now a small black pit had already exploded on the ground. What surprised him even more was that a tree that was one step away next to him was inlaid with many pieces of broken porcelain, and some of the barks were even lifted up by whole pieces. Just looking at this alone was enough to show the terribleness of the gunpowder.

Seeing the power of gunpowder so strong, Li Shimin's face became more gloomy. Finally, he couldn't help but yell at Li Xiu: "You actually asked me to hold such a dangerous thing in your hand just now. Do you want me to kill me?"

"Why are you angry? I'm standing next to you too? If you explode in your hands, I will definitely not be able to escape!" Li Xiu said calmly. In fact, he had not thought of killing Li Shimin directly, but if Li Shimin died, he would definitely not be able to escape. Moreover, Princess Pingyang and others who were surrounded might also face the furious Tiance Army, so this is definitely not a good idea.

"You..." Li Shimin was even more annoyed when he saw Li Xiu's calm appearance, but he couldn't find any refutation. He could only stare at him fiercely, but his evaluation of Li Xiu in his heart increased to a higher level. He even doubted whether the entire Tang Dynasty could still find talents like Li Xiu?

Li Xiu also walked over to see the explosion at this time, and even took a piece of porcelain from the bark to look at it. Then he curled his lips and said with some disdain: "The power is still too small. If the material can be purified and the shell can be changed to pig iron, then the power will be even greater!"

"Is this powerful still a little?" Li Shimin looked at the porcelain pieces on the bark, and then asked incredible ways.

"We in the Tang Dynasty now use weapons such as swords and other weapons when fighting. These weapons can be called cold weapons. With the emergence of gunpowder, I can design many weapons based on gunpowder, which can be called thermal weapons. When the thermal weapons reach the extreme, one weapon can even appear to slaughter the city and destroy the country. For example, in Chang'an City, a million people only need one weapon to prevent the entire Chang'an City from growing!" Li Xiu said seriously.

Of course, Li Xiu said this mainly to scare Li Shimin. Nuclear weapons seem to have exceeded the scope of thermal weapons, but no one can expose him anyway, so he can say whatever he likes.

"Then can you help me create the kind of weapon to massacre and destroy the country?" After seeing the power of gunpowder, Li Shimin believed in Li Xiu's words, especially thinking that Li Xiu had been able to destroy a large casino in an instant, so no one dared to say that he did not have the ability to destroy a city in an instant.

When Li Xiu heard Li Shimin's words, he couldn't help but roll his eyes, and then wrote a "e=m2" mass-energy method on the soil on the ground, then looked up and asked Li Shimin, "Can you understand this?"

"This... seems like a calculation formula?" Li Shimin looked at it for a long time, then said with shame. He had learned Li Xiu's book "Li Gongzi's Arithmetic" and could also calculate some mathematical problems, so he could see that this is a calculation formula, but it is impossible to understand this mass-energy equation. In fact, Li Xiu only remembers this great calculation formula. If he was asked to explain the meaning of the equation, he might not be able to say it.

"This is called the mass-energy equation. If someone can understand the meaning of this equation in the future, it is possible to create a terrible weapon that can massacre cities and destroy countries. However, I still don't want this weapon to appear, because if there is a certain number of such weapons, it can even destroy the entire world. Then let alone the country, the entire human race will be extinct!" Li Xiu said again. He may not be as good as others, but he can beat anyone in the Tang Dynasty such as physics.

After hearing Li Xiu's words, Li Shimin couldn't help but show a meditative expression. After all, there were too many things in his words that subverted his imagination, so he needed some time to accept it.

"King Qin, I can offer you gunpowder. With this, it is not a problem to repel the invading Turks. In addition, I will also do my best to assist you in completing your imperial hegemony. Chengdao they will be exiled to America and will never come back. All this only requires you to nod your head. I wonder what the King of Qin wants?" Li Xiu then clasped his fists and saluted again, his face very solemnly.

Hearing Li Xiu's words, Li Shimin also showed a hesitant expression for a moment. As an excellent general, he could see the value of this gunpowder on the battlefield at a glance. It is no exaggeration to say that as long as it is used properly, there will be no army in the world that can compete with the Tang army, and he can also fulfill his wish to expand territory. Qin Emperor and Han Wu are just like this.

In addition, he also valued Li Xiu's promise. Compared with gunpowder, Li Xiu, a talent who presented gunpowder, is actually more important. In particular, Li Xiu has offered various important things before, such as wound suture, alcohol, water wheels, etc., and most importantly, high-yield crops such as corn and sweet potatoes. After promotion, I am afraid that the Tang Dynasty will be worried about hunger again, which is enough to prove Li Xiu's talent.

Moreover, Li Shimin also knew that Li Xiu was a lazy guy. If he didn't force him, he wouldn't do anything. Most of the things on it were taken out by Li Xiu when he was unintentionally or had other purposes. They were far from his true strength. If he could assist him with all his strength, it might have a greater impact on the Tang Dynasty.
