Zhu Fan was the first to jump out and return the goods, and the other vassal kings followed suit.

At the beginning, Zhu Yunxi opened up to sell armor, and they thought that they had picked up a big bargain, and they no longer had to look at the old man's face, they could buy it casually from the eldest nephew.

Then, they smashed the pot and sold thousands of armors, thinking that this time they could be invincible in the world, and they didn't have to be afraid of their eldest nephew doing things, right?

Who Cheng thought, this grandson turned his head and made such a thing, isn't this a sincere trick!

Zhu Chun and Zhu Bai also reacted, even if the joy of winning more than a thousand pairs of armor in a bet was diluted.

Now the two of them have only one thought, that is, can the armor they bought before be returned?

"Big nephew, you don't pay attention to it, Uncle Eleven is not thin on you, how can you even pit me!"

Zhu Bai didn't dare to be as casual as Zhu Chun, but he also complained writhingly.

"Imperial grandson, it's not easy for your twelfth uncle to save some money, look at ......."

Zhu Li listened to the complaints of the brothers, and then he realized that when he wanted to buy armor, Zhu Yunxi was unwilling to sell it to him.

Dare to love the eldest nephew and be close to him, I can't bear to pit myself!

Lao Zhu listened to the complaints of his uncompetitive sons, and he wanted to throw them all off the city wall.

What a shame!

The dignified Ming vassal king actually complained because of a few pairs of armor!

"Shut up!"

"Let our eldest grandson's men continue the military exercise!"

"And?"

Everyone was shocked when they heard this, and their hearts said that this kind of fast, far, and accurate fire gun had already given them a headache, could it be that the eldest nephew had a more powerful weapon?

In fact, there really is, Zhu Yunxi's artillery battalion has not yet been played.

As soon as Lao Zhu's words fell, Mei Yin took out two small flags again and waved them a few times on the city wall.

Not long after, the artillery battalion in the Jing Navy came into play.

The people standing on the city wall saw the soldiers driving the carriage and pushing out the black, large, and thick cannons, and they only felt a chill rise from the soles of their feet.

It was the first time they had seen such a huge cannon, and the thick muzzle of the cannon was extremely powerful at first sight.

In fact, the Ming Dynasty did not lack artillery, but lacked large artillery.

Because of the great difficulty of casting large artillery, the requirements for materials and processes are extremely harsh, even if it is a bowl that can only defend the city, it can only be cast with copper.

Lao Zhu also only cast a few thousand rods in the fifth year of Hongwu and allocated them to some of the guards to defend the city.

It's not that this thing is not easy to use, but the cost is too high and it is too easy to wear.

Because the bowl can be used as money when it is melted, the local guards will report the loss from time to time, and then let the court give a new one.

Lao Zhu usually lives in a simple house, and it is the first time he has seen such a cannon.

Relatively speaking, Lan Yu had seen this thing a long time ago, and when he was fighting Beiyuan *** in Datong Mansion before, Zhu Yunxi gave him a lot of cannons.

However, he has the same distress as Zhu Li, that is, the ghost knows that more than half a year has passed, and Zhu Yunxi, the grandson, has made up some good things!

In short, from his point of view, the cannons under the walls were not only thicker, but also longer......

When the vassal kings saw the black cannons being pushed up, they became even more silent.

A small firearm can break through armor, and such a thick cannon cannons can't knock people away?

As if he had guessed their thoughts, someone dressed the scarecrow in iron armor and a helmet.

At the same time, the distance of the target was also extended, until it was pushed to a thousand steps away.

Standing on the city wall and looking at the past, you can only see small black dots.

When everything was ready, the artillery battalion under the city walls was fired.

After a rumbling cannon sound, one after another shells carried blinding fire and smashed into the target group a thousand paces away.

When the cannonball hits the ground, it does not bounce like a normal cannonball, but explodes the moment it hits the ground.

The sudden explosion once again shocked the people on the city wall, and many people trembled and shouted in the direction of the explosion.

"How can this cannonball explode?"

"Oh my God, what did I see, the cannonball that landed on the ground could still explode!"

The main reason why everyone was so surprised was that the shells they had used before were all solid shells. Its main lethality is to rely on the propulsion of gunpowder, which fires solid shells and kills enemies by physical impact.

To put it bluntly, it is a gunpowder version of a trebuchet, and the role of gunpowder is simply as a thrust.

Zhu Yunxi wants to lead the industrial revolution, so naturally it is impossible to develop step by step, and he must choose to move forward by leaps and bounds.

Lao Zhu saw that the artillery below had been fired, and proposed on the spot.

"Guys, we can't see clearly from standing here, why don't we go to the scene and see?"

Zhu Yunxi hurriedly stopped Lao Zhu.

"Grandpa Huang, this must not be done!"

"The current artillery technology is not mature, so in order to avoid the occurrence of squibs or shells that delay the explosion, you should not go over and check it."

"If you really want to see it, stand on the wall and look through a telescope!"

After Zhu Yunxi said this, he took out a binoculars on the spot and demonstrated to Lao Zhu.

"You can always see things in the distance if you put him in your eyes."

"Oh?"

Lao Zhu took the letter suspiciously, looked at the explosion site thousands of steps away, and immediately saw a magical scene.

This thing seemed to have an immortal law, and it really pulled something in the distance close to him, allowing him to see it very clearly.

"Huh!"

"It's good!"

Lan Yu looked at the telescope in Lao Zhu's hand, and felt like a kitten scratching in his heart, and wanted to ask Zhu Yunxi for one, but because there were many people in front of him, he was embarrassed to speak.

Just as he was hesitating, he suddenly found that Fu Youde actually took out a cylinder and looked at the target in the distance.

"Old man!"

"What's in your hand?"

"Clairvoyance!"

Lan Yu said unconvinced when he heard this.

"Why didn't the old man have it?"

Fu Youde snorted coldly when he heard this.

"I'm the commander of the Jing Navy, and you don't even want to be a vice president, how can there be such a thing!"

When Lan Yu heard this, he snorted angrily and snatched the clairvoyant and looked at the target in the distance.

"Wow!"

"It's magical!"

"I can see it so clearly!"

Fu Youde saw that Lan Yu had never seen the world like this, and his face showed pride.

In fact, he has long known the power of artillery, and he has secretly practiced in the Jing Navy many times.

The reason why he took out his clairvoyance to look at it was just to confirm it, plus Qi Lanyu's guy.

Lan Yu looked through the clairvoyance, and saw that all the targets on the ground had been beaten horizontally and vertically, the armor pieces on the armor were scattered all over the ground and became iron pieces, and the helmet had also been broken in half.

As for the deep pits on the ground, they brought him a strong impact.

"His grandmother's, our nephew and grandson have really improved the artillery, which is much stronger than the artillery used in Datong before!"

"Old man!"

"Is it possible that the old man can train the artillery himself and get such clairvoyance?"

Fu Youde showed a hint of joy when he heard this.

"That's hard to say!"

"But with the generosity of the imperial grandson, you have made him the dean, how can he be embarrassed not to buy things for you?"

"As for training artillery......

"The emperor's grandson means that in the future, the main focus of the Army Academy will be the use of firearms and artillery......

As soon as Lan Yu heard this, she didn't hesitate in her heart.

"The old man will report to the Army Academy tomorrow and sell his life to that grandson for a few more years!"

Fu Youde happily echoed when he heard this.

"That's right!"

"We are killing talents, and it is only interesting to follow the imperial grandson, the imperial grandson uses you so much, you still hide at home all day and don't see anyone, but you don't know how to lift!"

During the time of the conversation between the two, Lao Zhu also watched all the target scenes.

After Lao Zhu saw it, the excitement in his heart couldn't be calmed for a long time.

He finally understood why the eldest grandson didn't take the vassal kings in his eyes, he held such a powerful cannon in his hand, who could he put in his eyes?

I'm afraid that in his eyes, he can abolish the imperial grandfather if he wants to, right?

Lao Zhu was so angry that he was about to cry when he thought of this, he always thought that the eldest grandson was still young, and he needed his imperial grandfather to hold up a piece of the sky for him, and he dared to love this grandson himself as a piece of the sky!

"Grandson...... You're so filial, woo woo woo ...... "

Zhu Yunxi was proudly waiting for Lao Zhu's praise, but he thought that Lao Zhu suddenly cried.

"Grandpa Huang, where are you?"

Lao Zhu grabbed the eldest grandson's hand and burst into tears.

"We want to thank you!"

"Thank me for what?"

"Thank you for not killing!"

"You rebel grandson has made such a powerful cannon, and you haven't even thought about killing the king and usurping the throne, shouldn't we thank you?"

"Uh-uh......"

Zhu Yunxi was directly confused by Lao Zhu's brain circuit, and said in his heart, why didn't this old man play cards according to common sense.

The vassal kings on Lao Zhu's side were also stupid, although they didn't have binoculars, they could still see the mess of the target range, and knew that the power of the artillery was huge.

However, they never imagined that their father would think of this when he saw such a powerful cannon......

Lao Zhu was angry when he saw the stupid look on his grandson's face, and he kicked his ass with "bang".

"Rebel Sun!"

"Say!"

"How much more to hide from us!"

The more Lao Zhu thought about it, the more angry he became, this rebel grandson renovated the palace and made a lamp that didn't use lamp oil without telling himself. Now that he has made such a militaristic heavy weapon, he has not revealed any news to himself.

This is still the result of keeping an eye on him and ordering people to monitor him every day.

If you let this rebel grandson out, you won't be able to turn the world upside down!

"Grandpa Huang, my grandson has nothing to hide from you, haven't you always been by my side?"

Lao Zhu was even more angry when he heard this, he did put a lot of eyeliner next to his eldest grandson, and the eyeliner did send back a lot of information.

However, just like the light bulb in the Heart Cultivation Temple, he has lived in it for almost half a month, and he hasn't figured out what is the positive and negative electrodes, and what is DC AC. I just know that you can't touch that thing, and when you touch it, you'll be numb!

He, the emperor, can't understand it, and his eyeliner that is still by the side of the eldest grandson can't understand it.

Therefore, every time the news report came back, the emperor and the craftsman created something that could emit light, and named it an electric lamp.

The emperor's grandson and the craftsman created something that could transmit letters, and named it the telegraph.

The emperor's grandson and the craftsman developed something that could be painted, and named it a camera.

The emperor's grandson and the blacksmith developed something that could fire gunpowder, which was named a new type of artillery......

Lao Zhu thought back to the wire newspaper he had read before and wanted to cry without tears, how could he read between the lines, who could tell what it was?

This is really not seen with your own eyes, you never know what the rebel grandson has made up again!

Lao Zhu grabbed the collar of his eldest grandson and asked gloomily.

"We heard before that you concocted something that could fly, and that thing could really fly?"

"Yes!"

"We've also heard that you can make something that can be painted, and you can draw a person's face with a single click?"

"Yes!"

「

We've heard that you're working on something that can be sent to a thousand miles, and as long as you write a letter here, you can receive it there?"

"Returning to the emperor's grandfather, it can only be done theoretically, but in practice it is far from that simple, you need to first translate the text into code, and then send the code over, and then translate the code into text after receiving it......

Lao Zhu can understand this, he just needs to know that the rebel grandson has not denied it.

"Medium!"

"Let's see it, you are really not bragging!"

"Is that what you want to do?"

Zhu Yunxi looked at Lao Zhu slyly when he heard this.

"Grandpa Huang, what are the things you are talking about?"

Lao Zhu glared at the rebel grandson and said.

"What other things can it be, the ones you told us before, the few things that can cause chaos in the world!"

Zhu Yunxi smiled and nodded.

"Of course!"

"It is precisely because of these skills that my grandson dares to do those things!"

"But the grandson also knows that if you want to hurry, you can't reach it, and until you are fully prepared, your grandson will not risk the world's condemnation!"

Lao Zhu heard the eldest grandson say this, and touched the eldest grandson's head with satisfaction.

"Not bad!"

"It's finally a bit like the emperor's grandson, hahaha!"

After Lao Zhu said this, he spoke again in a little silence.

"Take us to your workshop another day!"

Zhu Yunxi nodded like a chicken pecking rice.

"Uh-huh!"

"Grandpa Huang is always welcome to visit the Hope Academy to guide the work!"

"Let's teach a fart!"

"Let's just go and see what the excitement is, and see what new stuff you've come up with again!"

After Lao Zhu said this, he happily pinched and pinched the eldest grandson's face, and a layer of mist appeared in his eyes again.

At this moment, Lao Zhu finally understood that it was not Zhu Yunxi who deliberately concealed him, but that he, the imperial grandfather, did not care enough about his eldest grandson, and he didn't know his eldest grandson's ability at all......

The people on the city wall listened to the dumb riddle between the two grandchildren, and only said that they were lonely.

They didn't know what the big things were, and they didn't know what the two of them were talking about, but they only knew that what the two of them said was very interesting, like a mythical story.

Zhu Fan was even more disdainful, feeling that the pair of grandparents and grandchildren were blowing boundlessly.

Still flying, he dreams of flying, right?

As for the sound transmission of thousands of miles, a person's face can be drawn with a click, which is even more ridiculous than a dream!

Compared to their doubts, the place far away from the city gate tower was still immersed in the shock of artillery.

The North Korean envoy Lu Song was stunned, looking at the ruins in the distance and muttering to himself.

"This is the power of heaven!"

"The power of heaven is unfathomable!"

He decided to return to North Korea to report the matter to Li Chenggui, and asked his own king to re-examine the relationship between North Korea and the Ming Dynasty.

There are also the five hundred Jurchens who flickered before, if you can put it back, you should put it back quickly, but don't arouse the hatred of the Ming Dynasty.

Once the Ming Dynasty sends the Tiger Ben Division into Korea with such artillery, there is no city in North Korea that can resist it!

Annan's envoy Nguyen Zongliang was also shocked, and he was immersed in the power of the explosion for a long time and couldn't extricate himself.

At this time, he was only glad for one thing, that is, since the founding of the Ming Dynasty, they Annan have been quite respectful to the Ming Dynasty and have never taken the initiative to provoke trouble.

After the shock, Annan's envoy Nguyen Zongliang suddenly had a ridiculous idea when he looked at the smoking artillery under the city wall.

Since the Ming Dynasty is now so powerful and has such a powerful artillery, if he supports the lord of Annan, wouldn't the lord no longer have to fear the usurpation of power by his cousin Hu?

It's just how to say that the Emperor of the Ming Dynasty should be moved and the emperor should send troops to help Annan put down the rebellion?
