Luo Luo really didn't know what to do when Li De said this.

"Wait for me, let's go to the workshop later."

Li De spent a stick of incense on paper to draw the design of the hot air balloon, and the data he was able to provide was a rough description of the hot air balloon.

The exact size of the product will require craftsmen to make it and try it out before it can be confirmed.

The craftsmen who came to the workshop studied Li Dena's drawings, and the equipment used to heat the lift-off required coal and manual blowers.

The principle is not complicated, it is in the expansion of the Kong Ming lantern several times, the material is all cloth, if you are lucky, you may be able to hold on for some time.

"Metropolitan Governor, can this thing really fly, if the cloth encounters fire, it will burn, especially in the air, it is very dangerous like a Kong Ming lantern." Craftsman Road.

"You're right, how to make sure you don't crash the balloon is what you're going to look into next."

Li De posed a difficult problem to the craftsmen.

Mankind's dream of flying may start now.

"You guys just need to be able to fly for an hour."

Li De put forward a request, although the principle of hot air balloon production is simple, but it is really not allowed to create practical products.

No, because there is no modern chemistry to help make thermal insulation.

The craftsmen have all made Kong Ming lanterns, and in their opinion, if they want to meet the conditions for flying, hot air balloons can actually be made into dome openings.

In this way, the hot air will be lost through the middle opening, which has the advantage of effectively preventing the heating from burning out in a short time after lift-off.

The disadvantage is that it needs to increase the heat supply, and perhaps it is necessary to make an endoskeleton like a Kong Ming lantern to hold up the hot air balloon.

Li De does not have too high requirements for height, according to the plan, he can fly over the Luoyang city wall, and the hot air balloon only needs to meet the requirements of twenty or thirty meters into the air.

The higher the better, so that you can avoid being detected by the city guards.

The craftsmen were put into production when they learned of the request, and Li De also said that he would guide him in the workshop, and there were also red peony personnel who were going to carry out the rescue of the characters.

The purpose of letting them watch the process is to give them an idea of how the balloon performs, so that they can quickly get started when it comes to control.

Li De treats the hot air balloon as a one-time consumption item, and in order to strengthen the safety of personnel, a large bundle of rope is placed in the load-bearing basket of the hot air balloon.

Prepare to slide down with a rope and a special grip when the hot air balloon burns or is uncontrollable.

The height is uncontrollable, so the rope is prepared very long and mounted directly at the bottom of the load-bearing basket.

This is the most effective way for Li De to come up with an escape.

It took the craftsmen several days to produce a finished product, a giant hot air balloon held up with bamboo clips.

After successfully holding out for half an hour after a test flight, it burned down, and thanks to the rope towing of the craftsman on the hot air balloon, he managed to escape.

The purpose of putting the craftsmen at risk was to allow them to keep track of the data, and the hot air balloon that was made in a few days was a success.

Li De took Luo Luo and other red peony and others who participated in the action to watch.

"Dadudu, the hot air balloon is made, but to make the hot air balloon take off, it still needs to be assembled in Luoyang City to be used, but the red peony can't bring too many craftsmen to Luoyang, not to mention that there are so many materials to carry."

Luo Luo asked very sensibly, Feitian's plan is very good, but can it really be used?

"There will be a solution."

In fact, it is not difficult to make a hot air balloon, but it takes a little more effort, which is according to the speed of the Youzhou workshop, and the materials will be available in Luoyang City.

Li De wants to use Red Peony's agents, and in order to rescue Chen Shubao, he must use hidden people.

After another half a month, Luoyang's control of the city gate was still as strict as usual, the reason was that it was impossible for the Wagang soldiers to relax if they did not leave Luoyang for a day.

The royal family in Luoyang was under a lot of pressure, and the conditions publicly announced by the Wei State made the little emperor not know how to answer.

All of them were handed over to the courtiers to discuss, and now there are no generals in Luoyang who can fight, Wang Shichong actually took this opportunity to gain power, and he was not friendly to the people from Wagang.

The fundamental reason is that because of the relationship of interests, the Duke of Wei will be added to the official and become a knight, but all the generals in the Wagang soldiers will be generals, and if they agree, it will be equivalent to handing over the whole army and horses of Luoyang to Li Mi.

The courtiers may not be strong enough, and they may not even have a single soldier at all, but they will not lure the wolf into the house.

In the final analysis, they don't trust the Wagang soldiers, and if they are experiencing the collapse of the Han Dynasty, it will stink.

The courtiers were very cautious about this, and they were on guard against the Wagang soldiers from the beginning.

When they were still thinking about the interests of the big things, the people of Red Peony were all acting, and all kinds of materials and craftsmen tried their best to transport them to Luoyang.

Red Peony has long made people stare at the house where Chen Shubao was under house arrest, and he has been sneaking in secretly for half a month.

Borrowing the nearest distance to dig a passage to Chen Shubao's house, the weapon transported the materials for making the hot air balloon to Chen Shubao's house through a secret passage.

These things are done without God knowing.

The Sui court treated Chen Shubao very well, but the soldiers at the gate changed shifts to guard but there was no one inside.

If you think about it, you can guess who wants to stay in the mansion every day and watch a dead king.

It was because no one was in charge that the rescue plan could be successfully completed.

On this day, the moon was dark and the wind was high, the northeast wind was at least five degrees, the lanterns at the door were blown back and forth, and the soldiers in charge of guarding changed from five squads to two squads.

All the soldiers who could be drawn were incorporated into the city defense to prevent anyone from attacking the city, and the ministers were really afraid that many places that did not need too many soldiers to take care of them would be transferred away.

Chen Shubao was killed from Emperor Yang of Sui, and the new emperor was very low-key during this time, drinking and listening to small songs in the mansion every day.

However, listening to music was treated a long time ago, and today's Chen Shubao can't afford the five dancers, especially after the death of Emperor Yang of Sui, he is like a dead leaf swaying in the wind, swaying without roots, and finally buried in the soil.

Just when he was thinking nonsense, suddenly a lot of people poured into the courtyard, and when they saw him, they immediately explained their intentions.

Of course, it was forcibly taken away by the people of Red Peony.

At night, the craftsmen prepare the hot air balloons they need for an hour, light the coals and pour them into the furnaces that provide the heat.

Then I saw the hot air balloon rise and float away.

Suddenly, seeing a fire in the air and something Chen Shubao was carrying falling from the hot air balloon, the guards quickly broke into the mansion, but after searching, they did not find Chen Shubao.

The guards immediately pursued the hot air balloon in the sky, and a few others went to report to the palace.

Chen Shubao was rescued, and the impact was not very great, but the matter of using a hot air balloon to let people fly away attracted attention.
