Chapter 341

The people outside the No. 3 Research Institute are all in charge of doing odd jobs, and the main researchers are all inside. Except for the researchers, no one is allowed to enter there.

Now the people in the outer courtyard are still sewing the airbags of the hot air balloons. Everyone's handwork is very careful, for fear that it will be torn if it is too strong.

"Tat Tat Tat..."

A cloth weaver woman and an old carpenter are following Niu Si to the outside. These two are the main research leaders of hot air balloons. One is in charge of manufacturing the airbags of hot air balloons, and the other is in charge of manufacturing the bellows and hanging baskets of hot air balloons. .

"See Lord City Master." The weaving woman and the old carpenter saluted respectfully.

"How's the hot air balloon experiment going?" Liu Feng glanced at the two of them. The weaving woman is one of the best weavers in Xiyang City, and the old carpenter's craftsmanship is also among the top in Xiyang City.

"My lord, we haven't tried it yet." The old carpenter said timidly, he didn't dare to try it, he couldn't believe that they could make things from heaven.

"What's the progress?" Liu Feng frowned, and glanced at the person who was sewing the airbag. According to his estimation, it should be almost finished these days.

"My lord, it's finished." The cloth weaving woman said quickly, she was also a little uneasy, the airbag she was sewing was for the second test, and she was afraid that something might go wrong the first time.

In fact, both the old carpenter and the weaving woman are illiterate. Now they are learning while making. Many capable people in the scientific research department do this, and then teach the next generation. In just a few years, Liu Feng will reap the rewards. Most of the technicians who understand words.

"Go, take me to have a look." Liu Feng said calmly, it seems that he still needs to participate and give these people some courage.

Otherwise, the real fortress in the sky will not be built in the future, and the hot air balloon is just a small matter. As long as he has a way to mass-produce hydrogen, the airship will be built by him. That is the real fortress in the sky. There is no problem for hundreds of miles, and he will hold the air supremacy in his hands.

"Yes." The two said respectfully, and immediately led the way to the backyard of the No. 3 Research Institute.

"Master, can people really go to heaven?" An Li's brown eyes were full of surprise, she doubted the possibility of going to heaven.

"Yes." Fleur suddenly said indifferently.

"Uh..." Hu Er Niang was stunned for a moment, then rolled her eyes and said, "Yes, the bird clan orcs can go to the sky."

"Wait a minute, don't you know if you see it with your own eyes?" Liu Feng smiled lightly. No matter what era and world it is, people yearn to go to the sky and fly to the blue sky. This is the dream of many people. He also did this when he was a child. dream.

"Okay." The fox-eared lady's brown eyes were full of longing, and Mina and Eliza were the same. Flying into the blue sky and white clouds was something they had fantasized about since they were young.

Soon, a group of people came to the open space in the backyard, and they saw a delicate bamboo hanging basket, air bags spread on the ground, some charcoal, a wooden box and several ceramic jars.

"My lord, things are ready." The old carpenter said respectfully, if Liu Feng didn't come, they would try it two days later.

"Follow the method I gave, and get ready to start." Liu Feng said with a serious face, he didn't know if it would be successful, after all, it was the first experiment, no one could say for sure.

"Yes." The old carpenter took a deep breath and immediately called someone to help assemble the hot air balloon.

A hot air balloon is composed of three parts: a balloon, a hanging basket, and a heating device. The most important thing is the heating device, and Liu Feng replaced it with a bellows, which is the kind of hand-push wooden bellows.

The rope on the airbag is tied to the hanging basket, and then the bellows is installed, and the charcoal is put into the hanging basket, as well as several altars of high alcohol.

Then install a shelf above the hanging basket, put charcoal and pour alcohol on it, and start blowing with a bellows after igniting the fire, spraying hot air into the airbag, and strands of hot air are continuously blown into the hot air balloon.

A few minutes later, Liu Feng and others saw the airbag of the hot air balloon inflated, and gradually began to float up at an angle, and changed the charcoal once when it was about to float up completely.

"No, no way, young master, are you going to use this cloth bag to make people fly into the sky?" An Li said with wide brown eyes in disbelief.

"Yes, this is called a hot air balloon." Liu Feng smiled lightly. He turned his head to look at Fu Lei, and saw the girl staring at the hot air balloon without blinking her eyes. You could see veins in the hand that was holding his clothes. It got violent.

"It's floating, it's really floating." The old carpenter shouted happily, just like a child.

The hot air balloon had completely floated up. If it wasn't for the big rocks tied to it, it would have flown into the sky. This scene made the weaving woman burst into tears.

The old carpenter and the cloth weaving woman were under a lot of pressure. After all, they had never touched this thing, and they were afraid that what they made would dissatisfy the city lord.

Or, this is the thinking of most of the scientific research department. Liu Feng's invisible pressure is too great. After all, good treatment is based on seeing results. Simple people always feel that they have to pay back after eating.

"Lord Liu Feng, I want to go up." Fu Lei turned her head and looked straight at Liu Feng, her green eyes were full of longing.

"Okay." Liu Feng nodded. He glanced at Mina, Anli and Eliza, and they all saw desire in each other's eyes, and said softly, "Come one by one, don't worry."

This hot air balloon is small, and it can carry the weight of two people, no more.

"Young Master, let me come first." Maoer Niang stood up and said, she was afraid that the hot air balloon would be dangerous.

"No, I can't fly very high." Liu Feng waved his hand, and took Fu Lei's hand and walked towards the hot air balloon.

For the first test flight, it will definitely not fly very high, and the scientific research department is not very far from Xiyang City. He doesn't want the news of the hot air balloon to be exposed, which will definitely attract the prying eyes of some forces.

It's better to be low-key for the time being.

Chapter 0406 Fleur's request.

"Master Liu Feng, hurry up." Fu Lei dragged Liu Feng's hand towards the hot air balloon, she wanted to go up to the blue sky to have a look.

"Okay." Liu Feng had no choice but to keep up, but there was a smile on the corner of his mouth. The girl now has obvious mood swings, which is a good thing. Perhaps, this can become a breakthrough to understand Fu Lei's past.

Liu Feng came to the hanging basket, stepped into the hanging basket, turned around and wanted to reach out to hug the girl in, but when he saw the girl holding the hanging basket with one hand, turning over quickly and entering the hanging basket, he remembered that the girl was regarded as a killer cultivated.

"Okay." Fleur looked up at Liu Feng who was outstretched, with a hint of a smile flashing in her indifferent eyes.

"Okay." Liu Feng sighed, the elusive girl, he turned his head and shouted to the old carpenter standing beside him, "Put the rope."

"Yes." The old carpenter said respectfully, and quickly untied one of the ropes tied to the boulder.

"Stand firm." Liu Feng urged, he pushed the bellows, the flames rose all of a sudden, and the hot air balloon rose slowly.

When seeing the hot air balloon staggeringly leave the ground, everyone's breathing became short of breath, Mina's body was even more tense, and her blue eyes were worriedly staring at Liu Feng, for fear that she would suddenly fall off.

"Mina, Mina..." An Li grabbed Maoerniang's arm with her small hand, and shouted nervously and excitedly, "Young master, young master has really gone to heaven."

"Yes, yes." Mina replied dryly. She was very nervous and prayed in her heart that nothing would happen.

"It's... so unbelievable." Eliza covered her mouth with one hand, her emerald green eyes were shining brightly, and she was watching the hot air balloon that continued to rise. The scene in front of her had a great impact on her.

She never expected that besides the bird tribe orcs, there is actually such a way to make people fly into the blue sky. The image of Liu Feng at this moment is infinitely elevated in Elisa's heart, and she feels more and more mysterious, as if covered in fog. People can't help but want to explore.

"Great, it's a success." The old carpenter choked up, wiped away tears with his arms, and stared at the hot air balloon that was still rising.

"Hurry up, get the linen ready, hurry up." Niu Sisi roared, directing the linen cloth to be spread out below, in case it fell and could be picked up.

He was nervous. If something happened to the young master, he would be torn apart by his parents and brothers, let alone the people of Xiyang City, the entire scientific research department would be flattened.

The people on the ground were nervous, but the people on the hot air balloon were very happy. Liu Feng pushed the bellows from time to time, and now it has risen to a height of more than 100 meters. Gao was about to fly out of the valley.

"call……"

Liu Feng let out a sigh of relief, it was really cold up here, he turned his head and saw Fu Lei staring blankly into the distance, with a very fascinated look.

"What's the matter? Do you miss the feeling of flying in the past?" Liu Feng's black eyes flashed with pity, and he reached out to touch the girl's head.

For Fleur, who used to be able to fly freely in the sky, now she can only rely on hot air balloons to reach the sky, which is a very sad thing.
