"It is indeed not cheap, and you may not necessarily be able to buy these things with money in our hometown of Muyang Town." Yu Tianlu said, "These precious interest payments are part of the championship prize for our participation in the art competition."
"Winner of the art competition, you are so awesome!" Wu Lianzhi also gave the two of them a thumbs up, "But it seems inappropriate for you to be doing art now!"
"Who said I wanted to make art?"
"Then what are you going to do?"
"To make this hot air balloon really fly, it won't work without power. Now I want to build an engine for this aircraft."
"What about aircraft and engines? I can't understand it anymore, Xiao Lu."
"Azhi, it doesn't matter if you don't understand, just work quickly." Yan Yue said dissatisfiedly.
It turned out that just now, Yan Yue had tied two sandbags.
"Sorry, sorry, I'm here to help!" Wu Lianzhi said embarrassedly.
At this time, Yu Tianlu closed his eyes again. At this moment, many drawings of the hot air balloon energy furnace had appeared in his mind.
"General hot air balloons use blowtorches with fuel to provide heat. However, due to limited conditions, the blowtorch cannot be made and can only be replaced by others." Yu Tianlu kept rummaging through the drawings in his memory.
You must know that his biggest interest in the original world was to go to the library to find blueprints for various machines.
Those drawings that seemed boring to others seemed to be the most beautiful pictures in the world in his eyes.
Yu Tianlu could remember no less than ten designs of hot air balloons alone.
Finally, the hard work paid off, and Yu Tianlu finally found a dusty design drawing in the corner of his memory.
"That's it. The most primitive hot air balloon used firewood and coal to provide heat energy."
With a thought in his mind, those "Energy Gold" followed Yu Tianlu's imagination and slowly transformed into a black iron stove according to the ancient design in his mind.
A huge opening above the stove is used to release heat, and the circular furnace body below is used to burn firewood. Moreover, Yu Tianlu also specially improved the internal structure to reduce the danger caused by high heat as much as possible.
Wu Lianzhi walked to the big iron stove, hugged the furnace body with both hands and lifted it up with force, barely lifting the big iron stove more than one meter above the ground.
"Xiao Lu, your stove is not light!" Wu Lianzhi said and hurriedly put down the stove.
"Okay, it's done. Next, Ayue, help move the stove to the hanging basket!" Yu Tianlu said.
"Leave it to me!" Yan Yue walked over and lifted the iron stove with one hand, placing it in the middle of the hanging basket very easily.
"What to do with those sandbags?" Wu Lianzhi asked.
"Of course it is tied to the side of the hanging basket! Watch my operation." Yu Tianlu said and tied a sandbag to the side of the hanging basket.
The other two children also followed suit, and soon the circle around the hanging basket was filled with sandbags.
"With such a heavy iron stove and so many sandbags, it's strange that this balloon can fly!" Wu Lianzhi didn't believe that the balloon could take off.
That's not all. Yu Tianlu also asked Wu Lianzhi to push the firewood cart into the hanging basket.
"Azhi, you are really capable! This car is a big help!" Yu Tianlu praised.
"It's nothing. When I was young, I studied carpentry for a few days with Uncle Mou who lived next to my house." Wu Lianzhi said, "But it's just a pile of wood, and with the three of us, it feels like the hanging basket can't even fit in!"
"Azhi, don't worry, I'm sure I can fly." Yu Tianlu walked around the basket and said thoughtfully, "It seems there is something missing. By the way, it seems that this hot air balloon cannot stay in the air. In disguise!”
"Disguise in the air?" Yan Yue and Wu Lianzhi looked at each other, not knowing what Yu Tianlu was talking about.
But the next second, Yu Tianlu used the last bit of Yanjin to materialize a small propeller.
"With this, the problem will be solved." After Yu Tianlu said, with a thought, a hole appeared on the side wall of the hanging basket, which was just right for inserting the propeller, and it was exactly right.
"You two, hurry up! We're about to take off!"
"I want to see how this hot air balloon flies." Wu Lianzhi and Yan Yue hurriedly got into the basket.
Yu Tianlu drew 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 one to get into the hanging basket.
"What are you two still doing? Hurry up and add more wood to the stove to make a fire!" Yu Tianlu urged.
"oh!"
Wu Lianzhi and Yan Yue also got busy.
Three times five times two times, after a while, the fire in the stove started burning.
As the heat slowly rose, the balloon that was originally crinkled on the ground began to expand under the influence of the heat.
The firepower of the furnace that Yu Tianlu embodied was extremely powerful. Although it was not as good as the flamethrower in the original world, it was completely sufficient.
Not long after, 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 people.
"Good boy!" Wu Lianzhi looked up at the hot air balloon as big as a house and couldn't help being surprised, "Why did it become so big all of a sudden?"
"What's so strange about this? If it wasn't so big, how could we fly?" Yu Tianlu said with a smile.
While talking, the three of them felt the hanging basket shake a little, and there seemed to be a feeling of rising.
Yan Yue stuck his head out of the hanging basket and looked down.
I saw that the hanging basket was already floating more than one meter above the ground.
"Xiao Lu, we are actually floating!" Yan Yue couldn't hide his excitement.
"Azhi, please help cut the rope that is tied to the hanging basket now!" Yu Tianlu said.
"Leave it to me!" Wu Lianzhi materialized a sharp blade.
Immediately afterwards, Wu Lienzhi raised his knife and cut off the rope.
As the rope broke, the hot air balloon also rushed upwards, climbing a lot of height.
"Okay, Ayue will be relying on you soon!" Yu Tianlu said.
"Rely on me? What can I do?" Yan Yue said sheepishly.
"Let you control this hot air balloon!"
"I can't control such an advanced thing. If it breaks, the consequences will be disastrous!"
While he was talking, the hot air balloon carrying the three people had climbed three stories high.
"Don't worry, you just need to follow my instructions." Yu Tianlu said, and also looked at the timer, "We still have half an hour to arrive at the meeting point, so you will need to do your best by then!"
"If I have the strength, I still have it." Yan Yue nodded vigorously.
At this time, Wu Lianzhi looked at the rising hot air balloon and was filled with emotion.
Wherever he could see, he happened to be where he had tried so hard to climb.
"Look, this is where I just fell!" Wu Lianzhi pointed to a spot on the mountain wall that was full of scratches.
When Wu Lianzhi fell down just now, he fired several invisible air blades in panic, leaving many traces on the cliff.
You must know that Wu Lianzhi had just spent a lot of effort to climb to that position, and now they could easily cross that place in a hot air balloon.
"It seems that brains are 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 filled with respect.
After about ten minutes, the hot air balloon had reached an altitude of several hundred meters.
Waves of chill came over, and the three friends couldn't help but shiver.
"Why is it so cold here!" Yan Yue couldn't help complaining.
The three of them could only run to the stove and use the heat from the stove to keep warm.
"It's a pity that all the materials were used to make hot air balloons. Otherwise, I could have made a blanket or something for you." Yu Tianlu shivered as he spoke.
"Xiao Lu, you are so powerful, can't you just materialize the blanket?" Yan Yue asked.
"Why am I so good?" Yu Tianlu said with a self-deprecating smile, "With my current ability, without the help of concrete materials, the things I construct can only last for a minute or two at most. What's the use of it!"
"Then what should we do? Are we going to stay cold like this? In this hanging basket, we can't even move our muscles."
"Isn't it easy to exercise? You will have a chance soon."
When Yu Tianlu said this, the hot air balloon had already crossed the cliff.
"It's not even half an hour now, Ah Yue, it's time for you to take action." Yu Tianlu said while pointing to the handle next to the propeller.
Yan Yue held the handle tightly and asked tentatively: "Is it turned like this?"
"Clockwise direction, rotate hard, we have to get there as soon as possible!" Yu Tianlu said.
"Let me give it a try!" Yan Yue exerted force, and the propeller suddenly started spinning rapidly.
A spiral airflow pushed the hot air balloon rapidly toward the northwest.
Just a few minutes later, the hot air balloon carried the three people over the previous cliff.
"It looks like we can make it in time to take the exam." Wu Lianzhi finally felt relieved.
Just when Yu Tianlu and others were trying their best to rush to the exam gathering place, many candidates taking the formal entrance exam had already arrived at the entrance of the "Virtual Forest" in advance.
Among them are Lu Lianhai and others who ranked among the top three in the qualification examination.
These people also encountered some obstacles before reaching the "virtual forest".
Lu Lianhai and many candidates were blocked by a large lake that appeared out of thin air.
In order to pass through this lake, many candidates visualized various boats that they wanted to cross.
But the lake that was originally calm and calm suddenly changed.
Like a dragon making waves under the water, the waves were turbulent and overlapping, and they overturned the boats of several candidates at once.
What is in front of the candidates does not seem to be a lake, but is clearly a vast ocean.
At the critical moment, Lu Lianhai stood up. Relying on his familiarity with water, the top scorer in the qualification examination actually used the power of imagery to divide the lake into two.
Then Lu Lianhai led a group of candidates through the middle road.
Candidates from other routes also received help from the Zheng brothers and Zikui. Although it took a lot of trouble, 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 sharp decrease in the number of candidates, Cheng Kezhao couldn't help but frown.
"Teacher Cao, what's going on? During the qualification exam, 500 people passed! Why are there so few people now?" Cheng Kezhao asked.
Cao Huaxue took the registration list. There were only about 300 candidates signed on it. No wonder Cheng Kezhao was angry.
"Director Cheng, there is nothing we can do about it. Many candidates have made the decision to abstain in the past two days." Cao Huaxue said helplessly.
"What? Abstaining? What on earth is going on with these candidates!"
