Zhu Yunwen is naturally very curious about the good things in Mo Cheng's mouth, not only Zhu Yunwen, but also the five members of the cabinet.

The previous electrical experiments had already made them feel like their scalps were bursting, so how could they not be tempted by the good things that Mo Cheng specially introduced.

The group walked out of the Academy of Sciences and walked towards the location of the warehouse not far away, Mo Cheng called two technicians to open the warehouse, so that the treasured objects inside could see the light of day, and at the same time, they were also exposed to the eyes of Zhu Yunwen and others.

Almost as soon as he saw it, Zhu Yunwen had already blurted out.

"Hot air balloons."

The smile on Mo Cheng's face, who was standing on the side, froze, and then turned his head to look at Zhu Yunwen in astonishment.

How did the emperor know the name of this new object, that is, the name of this was just agreed upon by the Academy of Sciences, but it was only two or three days.

But then Mo Cheng was relieved again, everything in the world is simple in the emperor's heart, and it is nothing if he knows, so he spoke: "Your Majesty is right, this thing is indeed a hot air balloon, and it is improved on the basis of the Kong Ming lantern made by the prime minister of the first Shu Han." ”

As soon as the cabinet behind him heard that the object in front of them was improved by Kong Minglan, they knew where to use it.

Ascend!

The Chinese's quest for the sky has been around for thousands of years, and they have never stopped this desire.

There was a person named Tao Chengdao in the Hongwu Dynasty, who was the first person in the world's aerospace dream.

His self-made flying chess, with a kite as a wing, a bamboo chair as a load, and gunpowder arrows as a propeller, was the first to fly into the sky.

Although the result was a fall from the sky and a sacrifice of life.

However, the Chinese's dream of pursuing blue skies and white clouds did not stop there, and after the establishment of the Academy of Sciences, Tao Chengdao's disciples also participated, but this experiment was stopped by Mo Cheng.

It is true that the thrust of fuel can send people into the blue sky for a short time, but how to get back?

If you fly out, you will fall to your death.

If it is simply for the joy of that moment of ascension, then this experiment is meaningless.

So Mo Chengcheng set his sights on Kong Ming's lantern.

Make a large one that can be equipped with a hanging basket to carry people.

The technical difficulty of this is not a big cross for the current Academy of Sciences, and after a few years, this new, new Kong Ming lantern with a very different appearance and shape from the Kong Ming lantern was born.

The Academy of Sciences took the name 'Hot Air Balloon'.

"Since Mo Cheng can take me and the others to see it, it means that this thing should have achieved good experimental results."

"Those who know the ministers, Your Majesty too."

Mo Cheng picked the thumb brother and smiled happily: "When this thing was first developed, in order to ensure safety, the experiment has always used pigs and sheep and other livestock, and the weight of an adult is similar to that of an adult and placed in the hanging basket and lifted off.

At first, it was still dangerous, there were a few crashes, but now it has been improved many times to ensure that it is safe. If an adult man is put in the air, he can take off fifty zhang and float fifteen miles away and then slowly descend, and there will be no danger of falling from a height. ”

Fifty zhang in the air, fifteen miles away.

This achievement is naturally not worth mentioning for the well-known hot air balloon, but for several people in the cabinet at this time, it still caused a piece of exclamation.

"A man can climb into the sky and see the white clouds in his eyes."

This kind of thing makes people very excited to think about it.

"Not only can it be used for viewing, but it is also very useful in war."

Zhu Gaochi answered, talked about the military field very excitedly, and took great pains to cite examples: "With this thing, you can not only climb high to observe the enemy formation, but also look down and cover it with a rain of arrows." ”

He thought well, but Zhu Yunwen shook his head and poured a basin of cold water.

"Arrows are useless today."

This sentence immediately extinguished Zhu Gaochi's enthusiasm and made the latter laugh.

Yes, Da Ming is invincible in today's confrontation, so why use this skill.

Mo Cheng still smiled and said: "Traditional bows and arrows are useless, but what if they are paired with strange things." ”

"If there are any new inventions, don't sell them."

Mo Cheng beckoned a worker and explained two sentences, the latter left, and after a short time, he walked over with a small alley, handed the box to Mo Cheng, and retreated to the side.

Placing the box on the ground, Mo Cheng flicked the mechanical lock a few times and bounced it open, taking out a small iron sphere with an iron ring at the top.

This made Zhu Yunwen's eyes wider.

"During the Northern Song Dynasty, the alchemist Tang Fu offered fire and thunder to Song Zhenzong, connected the lead, ignited and threw it, which could injure several people." didn't first introduce what new invention he was holding in his hand, but Mo Cheng told a historical story first.

"The fire thunder is huge, easy to carry, ordinary strong men can carry a few, only need to break one can easily kill the enemy, Song Zhenzong is afraid that this thing will enter the thief's hand to assassinate the king and kill the driver is very disliked, once deserted.

At the end of the Southern Song Dynasty, Huo Leizi reappeared in the light of day and made many meritorious contributions on the anti-Mongolian front, so the manufacturing process of the object was simple, and the traitor Zhang Hongfan also searched for craftsmen to manufacture it for the anti-Song Dynasty.

After the Mongolian people went west, this thing spread to the far west, and last year an Arab merchant from the Academy of Sciences came to offer the treasure, which was their own improved fire thunder.

Based on this, the minister made improvements, supplemented by the new explosives of today, which was named the throwing bomb by the minister.

Pull down this ring and throw it, and the internal striker will hit the flint and ignite the explosives, and the metal shell made of the shell will be shattered, even within a zhang, and the triple armor will also be pierced, and the power is really terrifying. ”

Zhu Yunwen already felt that his face was numb.

This is a grenade.

Of course, this grenade is really not technically difficult.

During the Northern Song Dynasty, it could be put into use on the battlefield, if it weren't for the royal family's concern for their own safety, decades of improvement and progress, how difficult would it be to get a grenade.

And if there are really grenades, how can it be Yue Fei's turn to smash the Yellow Dragon directly, and bring out a formed grenadier, which can blow up to the Bering Strait.

What a contribution the Mongol expedition to the west helped the progress of Europe.

In the same period of China, in the late Ming Dynasty, Chongzhen years, was still beaten by the Jurchens, and the Europeans were already equipped with flintlock pistols, Hongyi cannons, and formed grenadiers.

This is how the gap between the times appeared.

Dai Zi made 28 guns and Weiyuan General Cannons, but they were abandoned by Kangxi and banned research and development, and even exiled Dai Zi, causing the latter to die of starvation.

Otherwise, the world's first rear-loading gun must have been developed by China first.

After thinking about it in his heart, Zhu Yunwen exhaled a long breath: "Throwing explosive bombs is not good, I will give you a name, let's call it a grenade." ”

Mo Cheng is naturally not allowed to do anything, and he responds to the next voice.

"This year is the 42nd year of the Emperor's reign, so let's call it the 42-type individual grenade."

Zhu Yunwen smiled: "This thing is equipped with a hot air balloon, it is indeed a battlefield god soldier, and it is invincible." ”

After laughing, Zhu Yunwen looked at Mo Cheng again: "But there are still good things." ”

The latter shook his head.

"Really?"

"Back to Your Majesty, it's really gone."

"It's okay, I'm receptive, I can come here."

"It's gone."

Seeing that he really couldn't squeeze anything good from Mo Cheng, Zhu Yunwen laughed and waved his hand: "Okay, today is really a good day, I am already content, the carrier has worked hard for you, and I will draw up an edict to commend all the academicians and craftsmen of your Academy of Sciences." ”

"Ministers and Ministers of the Academy of Sciences, thank Your Majesty for your grace."
