For this flight, Alan found a few passengers to fly with him in a hot air balloon.

Of course, in order to ensure that there are no accidents during the flight, the people Alan is looking for are all acquaintances.

Among them, Efeena's two little Lori were selected by Allen, and the two who usually learn the most diligent and in-depth in school are the two of them, in order to reward their diligence and studiousness, two places are naturally given to them.

No, the two cat-eared Lori couldn't wait to run to the wooden box of the hot air balloon, patted the sandbag hanging on the wall of the wooden box with their little hands curiously, and said glutinously: "What is this?" ”

"It's sandbags, and you can increase altitude by dropping sandbags when you fly into the air." Alan laughed.

"Oh, we're going in, hug!" The staff hurriedly squatted down and carried them into the wooden box.

When the two of them entered, the deputy city lord Windsor also came, and as soon as they entered the wooden box, they were climbed up by the two Lori.

Alan stepped into the wooden box, beckoned to the people, and nodded to the staff.

"It doesn't matter, are we really okay?"

"It's okay, don't I have two children with me, how dare I bring the children up if I don't have confidence." Alan smiled.

Before taking off, he identified the attributes of the hot air balloon, and its quality was qualified, and there was no need to worry about the sudden air leakage when flying into the sky.

"Don't be afraid, we protect you, Sister Windsor!" The two little Loli grinned and were very brave.

Windsor was quite nervous, but seeing Allen's confidence and the smile given by the two cat-eared Lori, she also found some confidence.

The orcs in the square are nervous and excited, this can witness the first step of the orcs to conquer the blue sky, can they not be excited.

As the orcs lifted the ban, they untied the rope, and the hot air balloon literally rose into the air and slowly floated up.

"Wow!"

The square erupted in fierce cheers, and they hugged each other excitedly.

"Fly, hot air balloon fly!"

"It's incredible, praise to science, praise to Lord Allen!" The fanatical orcs fell to their knees and made a sound of adoration at the balloons that flew into the sky.

Fanatical, proud, proud, euphoric, the Pigeon Square was filled with all sorts of emotions, and even the pigeons flew in fright, flying around the hot air balloon, very curious about the take-off of this behemoth.

Alan stood in the wooden box, holding two little Loli in both hands, and the two cat-eared Lori poked her head out of the edge of the wooden box, looked at the ground, and saw the nervous Father Hoth.

"Haha, Daddy!" Little Ena beckoned to the Minister of Education under the balloon.

His dad shook his arm too, he was also excited, but the nervousness was a little more, after all, his two precious daughters were also on it.

When he heard that his daughter had won the first flight qualification, he was so happy that he couldn't sleep, but after seeing the hot air balloon take off, his heart hung up, his mentality changed greatly, and his mouth kept saying that he should not leak, not leak, not leak......

"Don't worry, my dear, the two city lords are also up there, they won't joke with their lives." Hoss's wife hugged him and cheered him up.

"Don't stretch your neck, be careful of falling."

On the balloon, Windsor pinned the excited Efe half of her head so that she wouldn't fall out.

Ena gloated, but unexpectedly pressed her cat's ear with her other hand, "Don't! ”

"Obedient, good." After Windsor pressed the two loli, she had time to look under the hot air balloon.

At this time, the hot air balloon had risen to a height of 100 meters, and in her eyes, the overall size of the house had become smaller, the orcs had become smaller, and all the tall things had been shortened, but it didn't feel very obvious.

Until two hundred meters, three hundred meters, four hundred meters, five hundred meters, the wide field of view flying high in the sky stunned Windsor.

In her sight, all the buildings were the size of small stones, and the crowd became the size of ants, no, they were even smaller than ants.

"How's that, shock." Alan laughed.

"Well, it turns out that the high-altitude perspective is like this, as if the horizon has become bent, which reminds me of a sailing story told by the young master in class, the people on the shore always see the mast first and then the hull when they look at the ship on the horizon."

"Isn't this the story of the planet being round, we remember it!" Efiena brushed her presence angrily, and looked at the ground by the way.

"Wow, the horizon really seems to be a little bent."

"Now the curve doesn't feel obvious, raise it a little more and feel it." Alan unsealed the four sandbags one by one, and the hot air balloon rose higher and higher, gradually rising to an altitude of 900 meters.

At an altitude of 900 meters, the temperature is different from the ground, it is relatively cold here, the two little Loli can't help but shiver, and Windsor also sneezes.

"Is it cold, I forgot to tell you to wear too much." Alan saw the reaction of the two of them, and then remembered that it was January, and it was winter.

The trio shook their heads, their minds not cold, but staring at the horizon, and sure enough, it felt a little rounder.

Another point also verifies that the knowledge of the class is useful.

"The temperature is significantly lower than the surface, and I remember being said in geography class that for every certain rise in elevation, the temperature drops by a certain degree, so how many degrees has it dropped now?"

The two little Loli showed a desire to learn at this time, muttered to themselves, and began to calculate the formula of altitude and temperature.

But they didn't have the value of the planet, they didn't know what the altitude was, and they couldn't quantify the temperature at the moment, so they could only ask Mr. Allen for help.

Alan naturally knew how many degrees it was now, his lips moved slightly, and Alan reported a few approximate figures, which were the altitude, the current temperature, and the temperature on the surface just now, and let the two little Loli calculate slowly.

Windsor is too lazy to do math problems, she obviously came to enjoy it, how can she do math problems while enjoying, you must know that tedious calculations are not a wonderful interest for most people.

……

In Pigeon Square, the orcs couldn't help but marvel as they watched the hot air balloon fly higher and higher, and then turn into black spots.

The balloon fluttered in the wind and flew south, and the orcs moved south to see where the balloon landed.

In the crowd, Olife, a former salted fish merchant, looked excitedly at the black dot that was far away, and also followed the crowd, chasing the hot air balloon together.

"Lord Allen is so powerful, he can't even fly into the sky, it's comparable to a god!"

"If I continue to stay in Shuizhu Port as a miser, I won't be able to enjoy a high-class life in this life, but fortunately I chose Tomorrow City." Oliver muttered to himself, excited and happy.

Like those nobles who are guarding Shuizhu Harbor and hesitating, even if they don't regret it now, they will definitely regret it when the city soldiers come to the city tomorrow.

When the time comes, the nobles will be relegated to commoners, tsk, just think about that scene...... Olivee shook his head, shook off thoughts that had nothing to do with him, and continued to chase the balloon feverishly.

The whole city was in turmoil.
