During this period, Yang Muyun studied a lot of relevant information on hot air balloons.
One of them is to fill the balloon with hydrogen, which can produce great buoyancy because its density is smaller than that of air.
The principle is similar to the fact that wood can float in water.
However, this method has great disadvantages: hydrogen is unstable, flammable and explosive, and it explodes when it sees an open flame.
Another way is to rely on heating to expand the air and create buoyancy.
Similar to Kongming lantern.
In terms of buoyancy, hydrogen balloons are stronger than hot air, and there is no need to worry about hydrogen filling once, and hot air needs to be constantly burned and heated.
But in terms of stability, hot air balloons are better.
Because it can land at a constant speed during a failure, it has a buffering effect. Even if the situation is more urgent, it can leave enough skydiving time, which is considered an extra insurance.
The hydrogen balloon will explode if it explodes, and it will be burned to death before it hits the ground.
And manipulation.
Hydrogen balloons can only rise, and landing depends entirely on deflation, but inflating them after deflation is a problem. Hot air balloons can be raised and lowered by controlling the amount of firepower, and can be lifted and lowered repeatedly, which is very convenient and fast.
The Slime God produces special slime descendants, which can store a large amount of air like a balloon, and is completely sealed and will not leak.
A knee-high slime can reach a large room after inflating and expanding, and the buoyancy generated is enough to bring a person and a hanging basket.
But Yang Muyun was still not satisfied and felt that the slime could be bigger, so Limlu returned to rebuild it and continued to improve his descendants.
This time, Yang Muyun brought the second generation slime. His body shape has not changed much. He is still tall and his knees are the size of a room when he expands. This is the limit of the slime. The most trashy creature, there is nothing.
It can be improved.
However, Limlu gave these descendants a fusion ability.
If the quality is not enough, it depends on quantity. Yang Muyun is politely polite.
The royal family members continued to create hydrogen, and the slime continued to capture hydrogen, and quickly expanded, rising little by little, leaving the ground.
At this time, Yang Muyun took out the net bag that had been prepared long ago to cover the slime, and asked someone to connect the lower end of the net bag to the lock ring of the hanging basket.
Slime constantly captures hydrogen, and its body expands rapidly, and rises up to support the net bag.
The two slimes are closely linked to each other and produce countless tiny velvety granulations. The dense granulations are like grapefruit meat, which makes people unable to see directly, but these granulations are tightly inserted into each other, quickly eliminating and fusing.
When the two large balloons are fused together, you can see the fusion part in the middle at the beginning, just like the buttocks on both sides of a peach, but it quickly becomes a round one, regardless of each other.
Yang Muyun couldn't help but sigh: Slime is really a magical species. As a biological Slime, it is undoubtedly a failure, but as a thing, Slime is successful again.
Whether it is the raw materials of the previous flesh and blood factory or the current hot air balloon balloons, Slime can be regarded as a pillar of the country and has shouldered the foundation of industrialization alone.
"Rise!"
"Oh my God, I really flew up!"
"Miracle! This is a miracle! Praise the gods!"
As the eyes of thousands of pairs of eyes, the two slimes flew up little by little with hanging baskets, and the ropes in the net bag were also stretched out little by little, and a creaking sound was heard.
Yang Muyun signaled to the old man to "go up".
The old man hesitated for a moment, and finally turned over and entered the hanging basket quickly.
The balloon sank slightly, and the old man felt like he was stepping on a boat board. He swayed slightly and quickly got used to it.
At this moment, Slime captured more hydrogen and rose up again.
Yang Muyun signaled a few more people to go up, and the royal family members immediately did as they did.
Finally, the slime expanded to its limit and there were four people in the hanging basket.
Looking at the balloon slowly rising and finally hovering at a height of hundreds of meters, Yang Muyun thought to himself: The load capacity of a slime is about two adult men, which is OK.
Anyway, slimes have the ability to fusion, so if they don’t have enough buoyancy, use the quantity to make up.
Besides, hanging baskets and net bags are all ordinary items. If you use magical materials, alchemy methods, or even some divine power, you may be even higher.
"landing!"
After receiving the instructions, several small holes appeared on Slime's body, and he exhaled slowly with hissing sound, and the balloon landed little by little.
All four people who went to heaven had their legs sore and weak, and their faces were pale.
It can be seen that the few of them were scared.
Thinking about it, it was dizzy when I looked down at a height of hundreds of meters, let alone the hanging basket that was leaking from all sides and was constantly swaying.
Not only were these people not scared, but they inspired a strong fighting spirit.
I remember how helpless the ancestors of the royal family were chased by the Church of Light and came to the north and settled on the banks of Moonlight Lake.
Faced with the thousands of miles of smoke waves and various powerful monsters that may exist under the water, the ancestors of the royal family's remnants did not choose to retreat, but instead faced difficulties and rushed forward, overcame all the way, subdued demons and demons, and finally conquered the lake and turned the natural danger into a barrier.
Now, they see hope to conquer the sky. If they retreat, they will not only shame their ancestors, but also their descendants.
"God! I beg you to give these divine beasts to our clan, and our clan will be carefully nurtured and taken good care of them."
A divine beast?
Hearing this, Slime God climaxed instantly, feeling that his world was filled with light.
ah!
Someone actually called him a divine beast, and it was the kind that was sincere, and it was definitely not casually speaking, because at the moment of speaking, Limlu felt a trace of faith floating out of human beings and landing on his forehead.
Really, I've been believed!
Limlu has believers, but all those believers are slimes. Except for their own tribe members, no other creature will look at themselves directly.
When playing with children in the tribe, they also play the role of being played, just a fun toy.
Although Limru likes to be played, Limru also hopes that he can be faced with it.
Now, a group of humans respectfully call themselves divine beasts, and even have faith in this regard, ah...
Limlu really didn't know what language to use to express his feelings, so he could only squeeze out two eye handles to look at Yang Muyun, blinking his big eyes and expressing that he was looking forward to it.
Of course, Yang Muyun would not refuse the requests of the royal family's survivors.
Flight tools are easy to make, but they are difficult for pilots to make.
The royal family members have the ability to make hydrogen, which means they can not only control hydrogen balloons, but also hot air balloons.
The most important thing is to save money.
No fuel is required, which can greatly reduce the load and can also ignite the fire to keep warm and cook.
In the past, the royal family members floated on the water, but in the future, the royal family members have the ability to fly in the sky.
At this time, a young girl said, "Great Elder, if we tie a hanging rope to the boathouse, wouldn't we make the boathouse fly? In that way, we can come and go freely in all the waters."
Yang Muyun looked at the young girl with satisfaction, and her mind was quite flexible.
The girl looked at Slime so frenziedly, as if there was a flame burning.
