"It's really not cheap, and we don't necessarily get these things with money in our hometown of Duyang." Yu Tianlu said, "These precious interest funds are part of the championship prizes for us to participate in the art competition. ”

"Art contest winners, you guys are amazing!" Wu Lianzhi also gave a thumbs up to the two, "But it seems inappropriate for you to make artwork now!" ”

"Who said I was going to make art?"

"And what are you going to do?"

"To make this hot air balloon really fly, you can't do it without power. I'm going to build an engine for this aircraft now. ”

"What kind of aircraft, engine, Xiaolu, I don't understand it anymore."

"Ah Zhi, it doesn't matter if you don't understand, just hurry up and work." Yan Yue on the side said dissatisfiedly.

It turned out that just now, Yan Yue had already tied two sandbags.

"I'm sorry, I'm sorry, I'm here to help!" Wu Lianzhi said embarrassedly.

At this time, Yu Tianlu closed his eyes again, and at this moment, many drawings of hot air balloon energy furnaces had appeared in his mind.

"Most hot air balloons use a blowtorch with fuel to provide heat. However, due to the limited conditions, the blowtorch cannot be made, and it can only be replaced by others. Yu Tianlu kept rummaging through the drawings in his memory.

You know, his biggest interest in the original world was to go to the library to find drawings of various machines.

Those drawings that seem boring to others seem to him to be the most beautiful pictures in the world.

Just the design drawings of the hot air balloon, Yu Tianlu remembered no less than ten.

Finally, the hard work paid off, and in the corner of memory, Yu Tianlu finally found a design drawing full of dust.

"That's it, the most primitive hot air balloons used firewood and coal to provide heat."

With a thought in his mind, those "Yanjin" followed Yu Tianlu's imagination, and according to the ancient design diagram in his mind, he slowly transformed into a black iron furnace.

A large opening above the stove was used to release hot gas, and the round furnace below was used to burn firewood. Moreover, Yu Tianlu also specially improved the internal structure to reduce the danger of high heat as much as possible.

Wu Lianzhi walked to the big iron furnace, hugged the furnace with both hands and lifted it up hard, barely lifting the big iron furnace more than a meter from the ground.

"I said Xiaolu, your stove is not light!" Wu Lianzhi said, hurriedly putting down the stove.

"Alright, you're done. Next, Ah Yue, help move this stove to the hanging basket! Yu Tianlu said.

"Leave it to me!" Yan Yue walked over and lifted the iron stove with one hand, and placed it in the middle of the hanging basket very easily.

"What about those sandbags?" Wu Lianzhi asked.

"Naturally, it's tied next to the hanging basket! Watch me in action. Yu Tianlu said and tied a sandbag to the side of the hanging basket.

The other two children did the same, and soon the circle around the gondola was full of sandbags.

"With such a heavy iron furnace and so many sandbags, it's no wonder that this balloon can fly!" Wu Lianzhi didn't believe that the balloon could be lifted into the air.

This is not the end, Yu Tianlu also asked Wu Lianzhi to push the firewood cart into the hanging basket.

"Ah Zhi, you really have the ability! This little car is a great help! Yu Tianlu praised.

"It's nothing, when I was a child, I studied carpentry for a few days with Uncle Mu who lived next to my house." Wu Lianzhi said, "But it's a pile of wood, plus the three of us, I feel like I can't put the hanging basket!" ”

"Ah Zhi, don't worry, I'm sure I'll be able to fly." Yu Tianlu walked around the hanging basket and said thoughtfully, "It seems that there is something missing." By the way, it seems that there is no way for this hot air balloon to disguise itself in the air! ”

"Aerial disguise?" Yan Yue and Wu Lianzhi glanced at each other, and they didn't know what Yu Tianlu was talking about.

But in the next second, Yu Tianlu used the last bit of gold to concretize a small propeller.

"With this, the problem will be solved." After Yu Tianlu finished speaking, as soon as his mind moved, a hole appeared on the side wall of the hanging basket, which was just right to insert the propeller into it, and it was exactly the same.

"You two hurry up and get up! We're about to take off! ”

"I'd like to see how this hot air balloon flies." Wu Lianzhi and Yan Yue hurriedly got into the hanging basket.

Yu Tianlu led a rope from the hanging basket, and then tied one end of the rope to a big tree not far away.

After doing all this, Yu Tianlu was the last to get into the hanging basket.

"You two are still stunned what to do, hurry up and add firewood to the stove!" Yu Tianlu urged.

"Oh!"

Wu Lianzhi and Yan Yue were also busy.

Three times five divided by two, and in a short time, the fire in the furnace began to burn.

As the heat slowly rose, the balloon, which had been crumpled on the ground, began to inflate under the impetus of the heat.

The fire power of the furnace embodied by Yu Tianlu is extremely fierce, although it is not as powerful as the flamethrower of the original world, but it is completely sufficient.

It didn't take long to see that the balloon that had just been spread on the ground like rags had expanded into a huge ball, floating above the heads of the three of them.

"Good boy!" Wu Lianzhi looked up at the hot air balloon the size of a house, and couldn't help but be surprised, "Why did it become so big all of a sudden?" ”

"What's so strange about this, how can we fly if it's not so big?" Yu Tianlu said with a smile.

While talking, the three of them only felt that the hanging basket shook for a moment, and it seemed to have a feeling of rising.

Yan Yue poked his head out of the hanging basket and looked down.

I saw that the hanging basket was already floating more than a meter above the ground.

"Xiao Lu, we actually floated!" Yan Yue couldn't hide his excitement.

"Ah Zhi, now I'm helping to cut the rope tied to the hanging basket!" Yu Tianlu said.

"Leave it to me!" Wu Lianzhi concretized a sharp blade with his hands.

Immediately afterwards, Wu Lianzhi raised the knife and cut off the rope.

As the rope broke, the balloon slammed upwards and climbed quite a bit.

"Okay, Ah Yue will rely on you in a while!" Yu Tianlu said.

"Rely on me? What can I do? Yan Yue said embarrassedly.

"Let you control this hot air balloon!"

"I can't control such a high-level thing, if it breaks, the consequences will be unimaginable!"

The hot air balloon carrying the three of them had climbed three floors as he spoke.

"Don't worry, you just have to follow my instructions." Yu Tianlu said, also looking at the timer, "We still have half an hour to arrive at the meeting place, so you need to do your best then!" ”

"I still have the strength, then I still have it." Yan Yue nodded vigorously.

At this time, Wu Lianzhi looked at the rising hot air balloon, and he was also emotional.

As far as the eye could see, it was exactly the place where he had worked hard to climb before.

"Look, this is where I just fell!" Wu Lianzhi pointed to a place on the mountain wall full of scratches.

When Wu Lianzhi fell down just now, in a panic, he shot out several invisible qi blades, leaving a lot of traces on the cliff.

You must know that Wu Lianzhi had just climbed to that position with great effort, and now in a hot air balloon, they easily crossed that place.

"It seems that the mind is far more important than brute force!" At this time, Wu Lianzhi looked at Yu Tianlu, who was observing the movements around him, and his heart was full of respect.

After about ten minutes, the hot air balloon has reached an altitude of several hundred meters.

A chill hit, and the three friends couldn't help but shiver.

"I said, why is it so cold here?" Yan Yue couldn't help but complain.

The three of them had to run to the stove and use the heat of the stove to keep warm.

"It's a pity that all the materials are used to make hot air balloons, otherwise I can make a blanket or something for you." Yu Tianlu shuddered as he spoke.

"Xiao Lu, aren't you so powerful that you can directly concretize the blanket?" Yan Yue asked.

"What am I capable of?" Yu Tianlu laughed self-deprecatingly, "With my current ability, without the help of concrete materials, the constructed things can exist for a minute or two at most, what's the use!" ”

"What can I do then? Are we going to stay cold all the time? In this hanging basket, even if you want to move your muscles and bones, you can't do it. ”

"Isn't it easy to exercise? You'll have a chance right away. ”

When Yu Tianlu said this, the hot air balloon had already crossed the cliff.

"It's not even half an hour now, it's time for Ah Yue to act." Yu Tianlu also pointed to the handle of the propeller next to him as he spoke.

Yan Yue clenched his hand and asked tentatively, "Is it like this?" ”

"Clockwise, rotate hard, we're going to get over as soon as possible!" Yu Tianlu said.

"I'll give it a try!" Yan Yue slammed his force, and suddenly the propeller spun rapidly.

A spiral air flow pushes the hot air balloon in a rapid northwesterly direction.

Just a few minutes later, the hot air balloon carried the trio over the cliff of the previous mountain.

"Looks like we'll be able to take the test in time." Wu Lianzhi's hanging heart finally let go.

Just when Yu Tianlu and the others tried their best to rush to the meeting place for the exam, many candidates who had taken the official entrance exam had already arrived in advance at the entrance of the "Virtual Forest".

Among them are Lu Lianhai, who ranked in the top three in the qualification examination.

These people also ran into some obstacles before they reached the "virtual forest".

Lu Lianhai and many other candidates were blocked by a large lake that appeared out of thin air.

In order to pass through the lake, many candidates visualized various boats that they wanted to cross.

But this originally calm lake changed color in an instant.

Like a dragon making waves underwater, the waves were turbulent and the waves were stacked layer by layer, and several candidates' boats were turned upside down at once.

In front of the candidates, it seems that it is not a lake, but an ocean.

At the critical moment, Lu Lianhai stood up. Relying on his familiarity with water, the champion of this qualifying exam actually used the power of imagery to divide the lake in two.

Then Lu Lianhai led a group of candidates to pass through the middle road.

And the candidates from several other roads also got the help of the Zheng brothers and Zikui. Although it took a lot of twists and turns, I finally arrived at the exam site safe and sound.

At this time, Cheng Kezhao had been waiting at the entrance of the "virtual forest" with a group of invigilators for a long time.

Looking at the sharply reduced number of candidates, Cheng Kezhao couldn't help frowning.

"Mr. Cao, what's going on? At the time of the qualification exam, 500 people passed! Why are you so many people now? Cheng Kezhao asked.

Cao Huaxue took the registration list, and there were probably only more than 300 candidates who signed in on it, no wonder Cheng Kezhao was angry.

"Director Cheng, there's no way around it. In the past two days, quite a few candidates have already made the decision to abstain. Cao Huaxue said helplessly.

"What? Abstention? What the hell is going on with these candidates! ”
