"That's nature!"

Ying Changsheng nodded.

"This thing, the principle is very simple, but he is powerful, my father turned around, can you be interested, sit on this thing, go to the sky to overlook my Daqin's rivers and mountains?"

"Oh? Sounds good, but I'll try it later, but of course, if this thing is properly researched, it won't be as dangerous as it is today! ”

Ying Zheng bowed slightly, and then sighed.

Ying Changsheng nodded, and then, Wang Jian on the side looked at the hot air balloon, and from time to time, he looked at the sky again.

He muttered thoughtfully.

"Your Majesty, I think this hot air balloon is of great use!"

"This thing is nothing more than to make people go to heaven, that is, for people to have fun, what is the use?"

Mao Jiao on the side has regained his composure at this moment, without the embarrassment when he first saw the hot air balloon, he is standing in place, pointing to the hot air balloon, pointing to the country, as if he really understands.

Wang Jian glanced at him disdainfully, and then he explained to Ying Zheng on the side.

"Your Majesty, do you know that in the past, when attacking a city, the most difficult problem is?"

"Naturally, it's over the city walls!"

Win the government without thinking.

When the city was attacked, it was faced with the towering city walls.

For the besieging side, it was a nightmare.

Ages.

No matter how good a general is, in the face of a strong city, when he is in danger, the method often adopted is not to attack.

Because, when attacking, it will cause huge casualties.

It's like Wang Jian when he attacked Wei State.

Facing the capital of Wei, Daliang, that is, Kaifeng in later generations.

Wang Jian did not rush and sent a large army to attack the city.

Because, Wang Jian understands a truth in his heart.

Siege words.

There will be heavy casualties.

Therefore, Wang Jian adopted a long-term attack.

That is, the siege.

Wang Jian found a water conservancy expert from the Great Qin Empire, Zheng Guo, a former Korean, and then built a canal to divert the water of the Yellow River next to it to the city of Daliang, and soaked the city of Daliang with water.

In the end, the city of Daliang was flooded with water, and the city wall was also collapsed by water blisters.

This led to the fact that the king of Wei took the initiative to lead his civil and military officials out of the city to surrender.

For an ancient famous general like Wang Qian.

It was so difficult to siege the city.

One can imagine how huge the obstruction of the army is by this wall.

At this moment, I only heard Wang Jian pointing to the hot air balloon on the ground, and then asked Ying Zheng.

"Your Majesty, if this hot air balloon carries three or five soldiers on it, and then, uses hundreds, or even thousands, of hot air balloons, wouldn't it be able to directly cross the city wall and deliver hundreds of elite soldiers to the enemy's city at one time?"

"This ......"

When Win Zheng heard this, his eyes suddenly lit up.

Indeed, this is a miracle plan.

With hot air balloons, so to speak.

You can let Daqin's elite soldiers descend from the sky to deal with Daqin's enemies.

Thinking of this, Ying Zheng's face was filled with excitement, and he nodded to Wang Jian with satisfaction.

"If Aiqing said yes, I think so, it seems that I will make this hot air balloon a lot in the future, in the past during the Spring and Autumn Period and the Warring States Period, I said that the country of a thousand times, the country of ten thousand times, now, probably in my opinion, it should be a country of a thousand balls, a country of ten thousand balls, a country of ten thousand balls......"

"Hahahaha!"

Ying Zheng's joke made everyone present can't help but let out a loud laugh.

At this moment, Ying Changsheng on the side opened his mouth again and said with a smile.

"Father, this hot air balloon has another wonderful use!"

"No, there are a lot of wonderful uses, and the sons are also for a while, so I can't finish it!"

"Oh? Tell me about it, boy! ”

When Ying Zheng heard this, he suddenly became interested, and asked towards Ying Changsheng.

And Win Changsheng also explained.

"This hot air balloon, after liftoff, is as high as dozens of zhang, even, hundreds of zhang high, at such a high altitude, as the so-called, ascending and looking far away, isn't it, the scenery within a radius of dozens of miles is in full view?"

"Huh?"

When Ying Zheng thought about it, he suddenly felt that it made sense.

At this time, Gong Yingli, who had changed into a clean dress in the distance, walked over, and he immediately agreed.

"Your Majesty, what the Nineteenth Prince said is extremely true, the minister was just on the hot air balloon, although he was frightened, but he also clearly glimpsed the scenery within dozens of miles of the surroundings!"

"If this hot air balloon is used on the battlefield, only one will be lifted into the sky, and then one soldier with excellent eyesight will be able to observe the surrounding distance......"

"There's some truth to that!"

Win Zheng's eyes lit up.

I just feel that it couldn't be more suitable.

And to win Changsheng, it is to continue.

"In addition, you can also send hot air balloons, in the sky, as scouts, you know, scouts on the ground are easy to be discovered by the enemy, and then killed, but with hot air balloon scouts, even if the enemy is dissatisfied, what can they do?"

"They, they can't wave their fists at the sky, can they?"

This sentence instantly made Ying Zheng and Wang Jian laugh.

Indeed, facing enemies from the sky.

Even if you are a good general, what can you do?

Just as Ying Changsheng said.

Are they still able to wave their fists and threaten the sky?

For a moment, everyone couldn't help laughing.

And Win Changsheng, but while the iron is hot, he continued.

"Not only that, this hot air balloon has another use!"

"Tell me about it!"

Ying Zheng hurriedly asked.

In his eyes now, this hot air balloon is already a weapon of the country.

And Ying Changsheng said with a smile.

"Father, do you still remember the black powder?"

"Oh?"

Ying Zheng was stunned for a moment, and Wang Jian on the side changed slightly, and then reacted.

He slammed his thigh and said.

"Yes, if you let this hot air balloon carry some bombs on it, wouldn't it be possible to drop bombs in the air, within the range that the enemy can't attack, and then kill and injure the enemy?"

"Hiss......"

When Ying Zheng heard this, he couldn't help but gasp.

If that's the case.

Then the war is much easier.

Even, there is no need for infantry to go out at all.

Just this hot air balloon can blow up an army alive.

Thinking of this, Ying Zheng couldn't help but sigh.

"You kid, if I was born twenty years earlier, then I Daqin and unify the world, I won't be able to use it, it will cost so many weeks!"

"Yes, the nineteenth prince is a talent, but it's a pity that he was born a little late......"

On the side, Wang Jian also said regretfully.

Nowadays, these weapons are really awesome.

However, in general, it will not be useful.
