After Mu Qiuxia successfully brought people to Fengyun, he was no longer worried that Gonglu Hammer and his clansmen had left, so when he saw Fengyun casting an inquiring glance at him, he immediately nodded slightly. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

After receiving a positive response from Mu Qiuxia, Fengyun was relieved and told Gonglu the truth: "The flying lantern will fly because the air will become lighter when heated, and I will find this because I see that white gas will rise when hot water is boiled in winter." ”

"What is air? Air is what we swallow out of our mouths and noses every day. Although it cannot be seen, we can prove that it exists. Just get some water, submerge your head in it, exhale, and you can see the bubbles coming out, which is air, that is, air. ”

As Feng Yun expected, Gong Lu Hammer also asked about the concept of air, and Feng Yun explained that it had a new understanding, and he immediately explained.

"Fengyun, why does the air become lighter when heated?"

Gong Lu Hammer's curiosity was very strong, and he was not satisfied with Fengyun's explanation, so he immediately asked another question.

He stared at a pair of big eyes, staring firmly at the wind and clouds, his eyes full of longing.

In fact, he was far more than the only one staring at Fengyun at this time, even Mu Qiuxia and Mulanozhi also stared at him, showing an expression of concern, obviously they also wanted to know the answer very much.

"This ...... I don't know, but we can work together. ”

Although Fengyun knew the answer, after a slight hesitation, he chose not to tell them.

Of course, he could tell them that this was because of the principle of thermal expansion and cold contraction, but he was worried that Gonglu Hammer would continue to ask why there was a phenomenon of hot and cold water.

If you want to explain this question clearly, it will inevitably involve more questions, and if Gong Lu Hammer keeps asking questions, it will be very troublesome, and he himself is not sure that he can answer these questions.

Rather than being asked a dry mouth and dumbfounded, it is better to answer directly now, although there may be some questions, but it is always better.

"Fengyun, you don't know. ”

Gong Lu Hammer didn't get the answer he wanted to know, he was very disappointed, his eyelids drooped, the glitter in his eyes dimmed, and the whole person looked a little decadent.

"Senior Gonglu, I think we'd better make a hot air balloon first. It's kind of an amplified flying lantern, and maybe we can figure out why the air gets lighter when heated during the production process. ”

Whether it is Fengyun or Mu Qiuxia, the purpose of inviting Gonglu Hammer over is to build a hot air balloon with his help and let it rise into the air, and quickly, naturally I don't want to see him decadent.

Fengyun's brain turned quickly, and immediately involved the problem with making a hot air balloon, driving his enthusiasm and making him go all out to make a hot air balloon as quickly as possible.

"Fengyun, you're so right. Doing nothing naturally doesn't know why. Where the hot air balloon is, we'll make it right away. ”

Gong Lu Hammer listened to Fengyun's words, his eyes lit up, his decadent aura was swept away, and his whole body was full of fighting spirit.

"It's right inside the cave. ”

The Storm Detective pointed to the cave behind him and smiled, knowing that his purpose had been achieved.

In order to figure out the problem that the air will become lighter when heated, Gonglu Hammer will definitely go all out to help him make a hot air balloon, and this is exactly what Fengyun wants to see the most.

"Everybody follow me into the cave. ”

Gonglu Hammer raised the metal sledgehammer high, pointed at the cave, and rushed towards the cave first, and the people of the Craftsman tribe immediately followed him.

Fengyun cast an apologetic glance at Mu Qiuxia and ran towards the cave as well.

Gong Lu Hammer and his people, although they are in high spirits and full of energy, it is obviously not possible to let them mess around by themselves, someone needs to command them, and Fengyun is obviously the most suitable person.

In order to prevent Gonglu Hammer and his people from making a mess of everything, Fengyun had to give up the opportunity to talk to Mu Qiuxia and immediately enter the cave to maintain order.

Fortunately, Fengyun already had the experience of commanding others to work, and quickly settled Gonglu Hammer and his people and assigned them tasks.

When Gonglu Hammer and his clansmen really started to do it, Fengyun had to admit that Mu Qiuxia's admiration for the craftsman tribe was reasonable, and their hands-on ability was indeed much stronger than ordinary people.

Even if he evaluates them through his eyes, they can get a good score, this is the first time they have started to do it, and if they are proficient, they should do better.

"The Artisan Tribe must be an ally of the Hundred Grass Tribe, and if possible, it is best to annex it completely. ”

Watching the people of the Craftsman tribe skillfully and orderly complete the tasks he assigned to them under the leadership of Gonglu Hammer, Fengyun couldn't help but have a thought in his heart.

In the eyes of people from other tribes, the people of the Craftsman Tribe may just be clever and have strong hands-on ability, but in the eyes of Fengyun, they have greater value.

Although he has a lot of inventions in his mind, it is not easy to make them come true, at least by his own ability.

However, he now sees the light that he can ask the people of the Artisan Tribe to help him.

What's more, some of the inventions and creations in his memory, he can't remember them clearly, or he just doesn't know why, and it will undoubtedly be more difficult to get them out, he needs a strong helper, and the tribe of craftsmen is undoubtedly capable of this role.

It was precisely because of the realization of the great value of the Artisan Tribe that Fengyun came up with the idea of annexing it and making it a part of the Flame Snake Tribe.

With the full help of Gonglu Hammer and his people, the progress of the work was greatly improved, and the first generation of hot air balloons was completed before it was dark.

According to Gonglu Hammer's idea, he immediately conducted an ignition experiment to see if it could fly, but in the end it was stopped by Fengyun.

Although he was also very interested in knowing the situation of the hot air balloon he had made under his own command, he knew that he could not be so hasty, at least not to conduct a test flight near a cave.

The cave is very hidden, which can effectively block the snooping of the crow's minions, and its location must not be exposed during the test flight.

In addition, he has the concern that he must not let the crow's minions know about the existence of the hot air balloon.

The hot air balloon is capable of manned flight, but its own defense ability is not strong, especially the ability to deal with long-range attacks, and in Razor, there is no shortage of archery skilled people in various tribes, and the Crow Tribe is naturally no exception.

If you let the Raven Ba know that the hot air balloon is a tool used by the Baicao Tribe Alliance to land on Crow Island and defeat him, I am afraid that before you get close to Crow Island, you will be treated with ten thousand arrows.

This is something Fengyun absolutely does not want to see. (To be continued.) )
