But today, when Zhu Wu heard Wu Zhi's idea, he suddenly felt like a long drought was coming.
He had great expectations in his heart, hoping that after Wu Zhi built this hot air balloon soldier, he would run across the battlefield and kill the Jin people and the Liao people to the point where they cried for their fathers and called their mothers.
When Wu Zhi and Zhu Wu came back from the back mountain, the sky was already getting dark.
Then the two of them went to Li Jie and Liu Laosan to check on their construction progress.
Although the craftsmanship of these craftsmen is quite good, they do not have any experience in building hot air balloons.
Currently, in their hands, they only have the construction direction of the hot air balloon.
But during the construction process, many of the details involved still require craftsmen like them to discuss, study, and ponder together.
A few days later.
The construction work of the first hot air balloon is finally completed.
And today is the day that this hot air balloon makes its first flight.
As for the test site for the first flight, Wu Zhi chose the back mountain of Shuibo Liangshan.
Here, the terrain is open and there are few people around.
Therefore, it is very convenient to conduct hot air balloon flight tests.
At the scene, in addition to Takeshi Zhuwu, there were many craftsmen responsible for building and designing the hot air balloon.
Liu Laosan and his master Li Jie were responsible for the operation and test flight of the hot air balloon.
At this moment, Liu Laosan was holding an inflatable tube specially made by ten ball craftsmen to fill the ball of the hot air balloon with air.
After the ball was completely filled with air, Liu Laosan carefully checked the ball for leaks.
After seeing that his requirements were fully met, the gas inside was released.
The next work was handed over to Li Jie.
Li Jie is responsible for the addition and ignition of fuel.
As long as the fuel is burned, the gas produced can lift the hanging basket.
Then Li Jie's work is completed.
For the sake of safety, Wu Zhi decided not to carry any pilot in the gondola for this test flight.
Just put ten chickens, ducks and poultry in the hanging basket to simulate the state of a real person in the hanging basket.
First, you can test whether the hot air balloon can still fly successfully when there are heavy objects in the hanging basket.
Secondly, you can also test whether the hanging basket is stable when it is in the air.
If there is shaking, what is the amplitude of the shaking left and right?
As the gondola rises above the basket, the oil-rich fuel burns more and more vigorously.
The huge sphere above the fuel is also expanding at an accelerated rate.
About a quarter of an hour later, as the sphere fully expanded, the hanging basket carrying more than ten poultry gradually left the ground and slowly rose upwards.
Before doing this experiment, Liu Laosan, under Wu Zhi's instructions, first installed a hook at the bottom of the hanging basket.
After the hook, another rope was connected and tied to a big tree not far away.
The purpose is to prevent the hot air balloon from getting lost out of control after it soars, which would be terrible.
At this time, as the hot air balloon rose higher and higher, the rope tied to the bottom of the hot air balloon was gradually tightened.
About two-quarters of an hour later, the hot-air balloon used for the test flew steadily to an altitude of more than 100 meters.
At this time, everyone raised their heads and looked at the hot air balloon that was made after several days of hard work at a height of 100 meters.
There was an extremely excited smile on his face.
The successful conduct of this hot air balloon flight test also demonstrates the feasibility of the Wu Zhi hot air balloon project.
When the craftsmen standing below spent a lot of effort to pull down the hot air balloon that was flying high in the sky.
That Li Jie, however, rushed to the side of the hanging basket, wanting to try the feeling of flying in the sky for himself.
However, Wu Zhi and Liu Laosan worked together to stop him.
For Wu Zhi, this Li Jie is their treasure on Shuibo Liang Mountain.
And this hot air balloon has only been tested once.
Therefore, all craftsmen here cannot guarantee its safety and stability.
If something went wrong during the subsequent test flight, Li Jie's life would be in danger.
This is something Wu Zhi would never agree to in any case.
After all, Wu Zhi will have many more inventions and creations in the future, which will be realized through the hands of Li Jie.
If it were his first test flight, he would have devoted himself to science.
So who will Wu Zhi look for to realize his future inventions and creations?
What's more, the current hot air balloon is not complete.
It cannot be allowed to continue to rise and fall under human control.
At the same time, as for the steering system and forward power system, the craftsmen have not yet equipped them on this hot air balloon.
At this moment, even if you sit on it, you can't experience much operating fun.
According to Wu Zhi's intention, after the complete body of the hot air balloon is completed, Li Jie can try it himself.
By then, with Li Jie's ability, he will inevitably make more rational improvements based on the hot air balloon.
A few more days passed.
The complete body of this hot air balloon was truly produced.
At this time, hot air balloons could carry three pilots at a time.
Two of the pilots are responsible for the pedal-type forward power system.
The other one is responsible for the turning system and lifting system.
Although the hot air balloon carrying three pilots was rising slower, its overall flight seemed to be smoother.
During this test flight, not only did Li Jie sit on it personally, but there were also two craftsmen accompanying him.
When Li Jie flew over Liangshan Mountain in the first hot air balloon of this period.
The feeling of seeing the small mountains at a glance immediately made Li Jie feel extremely happy.
In the nearby Liangshan Dazhai, more than ten soldiers on patrol were slowly moving forward.
Farther away is the slowly rising smoke at the foot of Liangshan Mountain.
A little further away is a prosperous town dozens of miles away from Shuibo Liangshan.
When the breeze blows, you can still see a line of wild geese flying over in the distance.
This feeling of being in the clouds was the most comfortable moment in Li Jie's life.
At the same time, he also admired Wu Zhi even more in his heart.
Although Wu Zhi was a craftsman, he didn't study very well, and he didn't even understand many basic knowledge.
However, he was able to accomplish this kind of flying feat through his own whimsical ideas that the world has never dared to imagine.
Such an amazing train of thought is rarely seen in the real world.
Anyway, I, Li Jie, will probably never have any fate with the Song Dynasty court in this life.
