Three days later, Tina found Chris and said excitedly: "I succeeded!"
At this time, the female magician's hair was messy, there were faint dark circles under her eyes, and she looked a little haggard.
Chris hugged her gently and said distressedly: "You should rest for a while. Don't worry about this. You can take your time."
"It's okay, I also like research very much, that's why I forget about food and sleep." After saying that, Tina took Chris's hand and ran downstairs, "Come on, let's go test it out."
The two walked out of the castle and headed west.
They came to an open place.
Nowadays, the construction area of Shuguang City is only one-third, so there is a lot of open space.
Tina took out a rattan basket from the space ring. It was about 1.5 meters high and about 3 by 2 in length and width.
Then she took out a four-legged wooden frame and fixed it on the four sides of the rattan basket.
The wooden frame is made of ironwood grown by Linda. It is hard, fire-resistant, and very light.
Immediately afterwards, Tina took out a huge basin with a diameter of about 1.5 meters, also made of ironwood.
If it weren't for Linda, a plant magician, it would be difficult to find suitable materials.
Tina finally took out an extremely huge cowhide airbag. There were many traces of sewing on it. It was estimated that at least forty or fifty pieces of cowhide were used.
Chris found that the seams were reflecting light, so he reached out and touched it, and found a layer of soft glue on the surface, so he asked, "What did you put on the cowhide?"
Tina replied: "It's magic aerosol, used to seal it, otherwise it will leak."
Chris smiled awkwardly and forgot about this incident.
There was a row of small holes at the bottom of the hot air balloon. Tina then took out a dozen tough vines, tied one end to the small holes, and the other end fixed the rattan basket.
Tina filled the brazier with coals and lit it with magic flames.
The raging flames rose up, blowing up the hot air balloon bit by bit.
When the hot air balloon was inflated, it slowly began to take off under the watchful eyes of the two people.
"Successful!" Tina was so excited that she almost jumped up.
Chris also had to admire this female magician. She simply explained the principle of the hot air balloon in her previous life, but she didn't expect it to be completed so quickly, and no one came to ask her during this period.
The two used floating magic to enter the wicker basket and took off together with the hot air balloon.
They need to try it themselves. If the hot air balloon fails and crashes to the ground, there will be no danger based on their flying abilities.
The sphere airbag is very large, as high as three stories high, so it looks like a huge thing.
"Oh my God, what is that?" Because the hot air balloon is relatively large, it quickly attracted the attention of many city residents.
"Things so big flying in the sky must be the creation of gods." Some people were so frightened that they fell to their knees.
"Could it be that a powerful flying monster came to attack the city? Go and report it to the Lord Knight!"
The appearance of hot air balloons caused a lot of panic in Dawn City. Some people were so scared that they hid in their homes.
"Look, it's Lord Chris!" The citizens with better eyesight saw Chris and Tina in the rattan basket.
Chris used his fighting spirit to spread his voice: "Don't be afraid, this is my newly developed secret weapon!"
"Oh, it turns out to be the lord's secret weapon, so it's okay."
"Such a big thing must be very powerful, right?"
Reputation 1 from Gista, 2 reputation from Zero, 1 reputation from Milo...
Chris looked surprised and said quickly: "Let's go over there and try to let everyone in the city see the hot air balloon."
They flew in a large circle over Dawn City, earning Chris more than 70,000 reputation points in total.
Of course, coal consumption is also very fast.
If they didn't have the space ring, just the small amount of coal carried in the rattan basket would probably run out of energy within a short time of flying.
After walking around in a circle until there was no more reputation, Chris said: "Find a place where no one is around and try throwing a clay pot bomb."
Tina controlled the hot air balloon and found an open area.
Chris took out a bomb from the ring, lit the fuse and threw it downwards.
"Snapped!"
The clay pot bomb was shattered into pieces before it even detonated.
"Raise it higher."
Tina let the hot air balloon start to rise again and stop after reaching a certain height.
Chris took out a bomb again, lit it and threw it.
This time it detonated successfully, scattering iron flakes all over the ground.
"That's great!" Chris hugged Tina happily and spun around in place.
Tina blushed and pushed him away, quickly saying: "We are almost out of fuel, let's go down first."
Chris let go of his hand, and the hot air balloon slowly landed in the open space.
They jumped out of the rattan basket, their faces full of excitement. This experiment was very successful.
Tina began to summarize the data: "The height when you throw a clay pot bomb is detonated is about 400 meters. If half of the basket is filled with bombs and half with coal, it can probably fly for about 20 minutes."
"Although the battery life is not long, I am very satisfied with the result." Chris smiled and said, "After you test it a few more times and measure the accurate parameters, we will start mass production."
Tina said in embarrassment: "I'm afraid it won't work. I have looted all the cowhide in Shuguang City. There are no more, so I can only build this one now."
"This is easy to handle. There is a prairie in the Shadow Leopard Kingdom in the north, and there are countless nomadic people living there. I immediately sent people with food to find them in exchange for cowhide and sheepskin." Chris said.
"Okay." Tina suddenly thought of something, "We can make the fuse of the bomb shorter so that it doesn't have to rise so high."
"No problem, I immediately ordered them to make a batch of short-lead bombs."
The success of the hot air balloon greatly encouraged Chris. When this kind of thing appears on the battlefield, it will definitely bring serious panic to the enemy.
When the time comes, just seeing this behemoth from a distance will frighten the enemy.
Tina went to find coal and prepared to continue testing the hot air balloon.
Chris returned to the castle and sent a manservant to watch over and prevent outsiders from getting close to the balloon.
He found Jonathan again, threw over a large bag of gold coins, and ordered: "You should clear out all the space rings now, then go to the city to buy food, and then go to the prairie to find local herdsmen in exchange for cowhide and sheepskin. There is no limit to the quantity. Return
Yes, bring a businessman who knows how to do business to accompany you and bargain with them."
"Yes!" Jonathan respectfully performed a knight's salute, stood up and left.
