"Why is this Kong Ming lantern so big?"
Everyone looked at the brothers and asked Sister Hong, "I will make it bigger in the future, this time it's an experimental experiment!"
Let's see!
”Du Yuhui said: Yes, the hot air balloon Du Yuhui of later generations will be brought out, especially in the military, the use will be more extensive, such as the enemy's city wall is very high, but what can be done, once the hot air balloon is developed on his side, then it can easily make the height of the hot air balloon higher than the city wall, at that time, every move in the enemy city will be exposed in front of his eyes, in addition, Du Yuhui's hot air balloon is not directly released into the air, but needs to be connected with an iron chain or rope, in this case, The hot air balloon can't fly away, and then she uses Fluttershy's sister to communicate with the people in the hot air balloon, even if it's just the people in the hot air balloon beating gongs and drums to deliver the news, right?
And once successful, Du Yuhui can make a lot of hot air balloons floating in the air, not to mention, if you can, you can use the wind direction from the air to launch a high-altitude strike on the enemy in the city, and if the enemy's defensive weapons on the city wall can not pose a threat to the hot air balloon, what will happen to the battlefield, the defending side has the advantage, it is necessary to wait for the enemy to attack themselves to consume the opponent's vitality, and as a result, the opponent uses the hot air balloon to carry out air strikes, and everything you have will be exposed to the enemy's eyes.
Whether the opponent attacks with a bow or crossbow on a hot air balloon, or a rocket or other tactical strike, and the enemy in the city can't fight back, isn't it like catching a turtle in an urn!
At the same time, if this trick is used on the sea, it will be even more shameless, right?
No matter how high the watchtower on your ship is, the hot air balloon can easily exceed this height, and there is no better lookout measure on the sea now, in a word, stand high and look far, as long as your hot air balloon is even one meter higher than the watchtower, with the cooperation of the high-power mobile telescope of the Jue Mansion, the observation distance is definitely doubled, right?
This is in a naval battle, to be honest, it can be said that it is from the perspective of God, right!
So Du Yuhui is starting to do this test now!"
Fly, fly, fly, so big can fly?
It's amazing!
”The sister-in-law followed and said: It is true that the external name of this experiment is Kong Ming lantern, but the size of this Kong Ming lantern is a bit big, dozens of times that of ordinary Kong Ming lantern!"
Is Du pre confident?"
Du Yuhui said: Yes, this thing is made by his concept Du pre-made!"
Hey, hey, second young master, we've experimented with this thing a few times and improved it a few times, but this time the second young master can rest assured, it will definitely succeed!"
Du Yu smiled and said, "Such a big thing?
You've all gotten to heaven?
”The third uncle walked over and looked at the rising Kong Ming lantern and said: It is true that this thing is a bit big, and it is probably not right to say that it is still called Kong Ming Lantern The third uncle, so I said so!"
Third uncle, this is Kong Ming Lantern, it's just a bit big, Ao is right, I'll let Du pre them test it well, if there is no problem, from tonight onwards, let them do more, and then we can suspend these things in the air in the first month, and then our lord's mansion can be lit up all night, isn't it!
Hehehe!
”Du Yuhui said with a smile: "Hey, dog!
Is this something you made again?
”Grandfather's voice floated from behind: Yes, after dinner, the family is left to play, I heard that the dog is doing something outside, naturally someone will come out to see the excitement, right?"
My son!
It's so bright!
This thing is so much better than the street lamps we made!
”Du Yuhui looked back at Liang and said, "Hehehe!
Of course, the chassis used for this big Kong Ming lantern is also large, and then hang more small lanterns on the chassis around the week to let it illuminate in the air, of course, brighter than a single street lamp!
”Du Yuhui explained: Yes, on the chassis of the big Kong Ming lantern, there are two lanterns tied to one side, which belongs to a Kong Ming lantern with 8 lanterns in the air, can it not be bright!"
The point is that this is flying higher and higher!
I'm going to fly away in a moment!
”The second uncle looked up at the Kong Ming lantern that was flying higher and said with a frown: "Second uncle, don't worry, I asked people to tie this large Kong Ming lantern with a rope, first see how high he can fly, and then pull it back!"
”Du Yuhui said: Yes, he also has to calculate how much refined coal can last for how long, these are all things that need to be summarized data, and then increase the volume to expand the capacity, increase the weight, etc., these are all problems that need to be solved slowly, today is to play!"
Otherwise, outsiders will always say, we dogs!
You won't lose what you've done, look at it, he's all playing!
”The second uncle said: "It's the second young master!"
”After the rope on Du Pre's side was put into the longest place, he immediately came over and said, "Oh?
Okay, pull him back!
Put it higher than the street lamp above our lord's mansion, how high it is, you can adjust it yourself, that is, let the brothers on the ground think that the lighting effect is the best!
Then go on a few more groups, and strive for our lord's mansion to use it before fifteen, and then it will be outside, and we will also have no dead end lighting, isn't it hahaha!
”Du Yuhui said: And the reason why Du Yuhui is happy is that the 10-zhang long rope test has successfully reached the standard!
Because there was no telescope, he could see the situation in the sky in Kong Ming lantern!"
Xiaohui!
You mean, in the future, we will use this method of lighting in our homes?

There's no dark place at night?
”When the third uncle heard this, he immediately asked: Indeed, because there are electric lights in later generations, and there are a large number of street lights, to be honest, it is difficult for us to understand what the mood is like at night."
Well, there should be no problem, the position of the rope, I will let people mark it, and don't scratch people when the time comes!"
Du Yuhui said: "This relationship is good, damn it, we don't deal with so many people, it would be bad if they let people enter our lord's mansion, now like this, don't say that we can see clearly, even the people who patrol at night can also see more clearly, or the dog is powerful hahaha!"
”The second uncle smiled and said, "Hey, dog!
On the eighth day of the new year, your second brother married, you asked Du to make them work harder, and strive for the night of our eighth day of the new year, the lord's mansion was as bright as day, and even if someone wanted to do something, wouldn't there be nothing to hide!
”When the second uncle heard this, he immediately said, "The eighth day of the first month?
That's right, second uncle, if you don't remind me, I'll forget, Du Pre, you have worked hard these days!
”Du Yuhui said: It is true that every time someone comes to the lord's mansion to make trouble, he doesn't know if this time will be an exception, but if the illumination can be increased, the enemy will have to weigh it!"
It's the second young master!
I'm going to get people out of the city right now!
”Du Pre said: Yes, that's what you say, but you don't have to do it this way, can a flying pigeon pass book solve the problem!
And they are striking iron, using the best coal, and at the same time they are also testing the larger volume and weight of Kong Ming lanterns, so it is too simple to make something that has been finalized at the moment!"
Look, everybody!
What's the Lord's Mansion?
Why is it so high and bright!
”"I don't know!
But it's so dazzling!
”"Where's that?
How do you get so many big lanterns?
It's still that high!
”"That's the Lord's Mansion over there!""
I'll wait until tomorrow morning to inquire!"
At night, when more hot air balloons appear for lighting in the Lord's Mansion, after all, because of its height, many people in the periphery of the Lord's Mansion can see it, even if it is a little farther away!
So there is a direct judgment that it is the lord's mansion, and there is a person who sees it but doesn't know who it is, there is no way, because of the height!
So this topic will soon sweep the entire Lin'an Mansion!"
If it weren't for the cold!
I want to play mahjong outside, look at how bright you are!
”The sixth uncle said under the Kong Ming lamp: "Second young master, everyone thinks that we are making this thing to replace the street lamp, who knows that you are going to send people up!"
”Du Yu has already entered the house with Du Yuhui, and the other brothers have continued, but the family has watched more and more Kong Ming lanterns rise into the sky, and the lord's mansion is about to be as bright as day, so there is no intention of going back, and the people who play mahjong have long stopped playing, and they all came out to see the excitement!
Du Yu said: "Well, if the experiment is successful in the future, don't say anything else, we will send people up during the day, and we can monitor the entire Lin'an Mansion hahaha!"
”Du Yuhui said with a smile: Indeed, if you use a telescope to observe the ground at a height of 20 zhang from the ground in the air, hehehe, right!"
Hey, hey, what the second young master said is very true, and I'm looking forward to that day!"
Du Pre said: It is true that Du Yuhui is a person from the past, he knows that this thing will be successful, and it is very simple, after all, this is much easier than producing other flying machines, right, but Du Pre has not experienced it, although after so many years, he believes in any words of Du Yuhui, but he also needs to see is not believing!
Anyway, for Du Yu, this manned hot air balloon or a large Kong Ming lantern is something unknown, right?"
Oh, yes, there's more!
Don't use this thing when it's windy and rainy, you know!
Try to use it when the wind is sunny and the sky is cloudless!
Especially in thunderous weather, it is easy to be struck by lightning!
”Du Yuhui said: "Second young master, don't worry, I've written it down!"
But don't we have a lightning rod in our house?
”Du pre asked: "The lightning rod is connected to the ground, and the weight of the lightning rod on the hot air balloon is not worth the loss!"
”Du Yuhui explained
