Attached to the bottom of the shark skin hot air balloon is a large rattan basket large enough for four or five people to stand, and inside it is stored cotton clothing, food and water, and a large thick quilt.

According to Liang Baoyu's design, after the hot air balloon lifts off, the people in the rattan basket will inevitably suffer far colder temperatures than the guys tied to the kite, and it is better to wrap a few more layers of cotton clothes after all.

As for the quilt...... When you feel cold, you can wrap yourself in the cold, in case of a crisis moment when the hot air balloon falls, it can also increase some anti-collision effect, as for the person who falls from a high altitude to wrap an extra layer of quilt can really save a small life...... Hey, that's a psychological comfort, seriously you're losing!

is different from the two donkeys who are extremely excited, even if they are promised heavy profits by their own little marquis, Laifu is still trembling, he really can't understand, with such a suitable human hand as the two donkeys, why does the little marquis have to let him fly again?

Unlike in the past, the Hyaki Division also selected a guy to fly in a hot air balloon this time.

This guy who doesn't even have a name is codenamed Jia San, cold and gloomy, like a puppet, with great skill and courage, and turned over and entered the rattan basket.

According to the operating procedures, the two donkeys lit the fire pot, and the scorching air flow quickly filled the shriveled hot air balloon.

This fire pot is made of 100 steel, and several masters in the secret workshop of the Ministry of Industry have worked together for dozens of days, and a total of more than 10 have been built, and the one currently used is the one with the best quality.

As the hot air balloon is completely filled with scorching air, it floats off the ground with the rattan basket and the people inside.

"Laifu, two donkeys, remember to do things according to the operating procedures, let's see you in Chang'an City!"

With a gentle smile on his face, Liang Baoyu waved his arms at the three people who were already floating in mid-air, turned his head and ordered to untie the rope of the hot air balloon tied to the ground.

"Uncle, rest assured, the little one will land the flying ball safely and securely in the experimental field of agriculture!"

The second donkey, who has countless experiences of playing with parachutes, does not have any timidity at all, but is gradually excited with the naked eye!

"Little Marquis, I'm afraid! Ahhh ”

Laifu's terrible howl sounded again, and everyone present was used to it, and even Liang Baoyu regarded this as a coquettish behavior of the other party to express his intimacy......

The spy named Jiasan nodded coldly at the big boss below Hong Cheng, as if he was not participating in some flying feat, but went out to buy a few fritters for the leader for breakfast.

As the rope was untied, the hot air balloon quickly rose in height, and in a few breaths, the people on the ground turned into small black dots.

"Brother Laifu, don't be afraid, let's operate according to the rules, and we will definitely be able to return to the ground safely."

The second donkey comforted Laifu, who was still crying bitterly, and began to adjust the spout of the fire pot with his hands and feet.

Rifle wiped the snot and tears from his face, and although he was still sobbing quietly, he also began to help according to the operating procedures.

Only the spy of the Hundred Horsemen Division was like a tourist who had paid for it, and he took out his single-hole telescope and continued to scan downward, as if he was secretly spying on his mother-in-law and stealing wild men.

"This big brother, the clothes on your body are too thin, put on this cotton coat first."

After the hot air balloon floated smoothly in mid-air, the second donkey took the initiative to hand over a spare cotton coat to Jiasan, "My uncle said that the sky is not much colder than the ground, and it is easy to have accidents if you don't pay attention to cold protection and warmth...... Uncle is really knowledgeable, this has not seen the palace where the fairy lives, it is already cold like this, the place where the fairy grandfather lives is afraid that it is colder than the winter on the grassland, right? ”

The second donkey's self-talk made the expression of Jia San, whose face seemed to be frozen, loosen somewhat, and it was rare to ask: "You also came back from the grassland?" ”

"Isn't that right? I was originally from the auxiliary barracks, and was brought back from the grassland by my uncle, by the way, Brother Laifu has also been to the grassland, he is more productive and capable than me, he brought back many cattle from the grassland, the kind that can be cultivated, and the uncle said that his credit is no worse than that of us guys who work hard with knives and people! ”

Jia San looked at Laifu who was still touching his nose in surprise, and suddenly felt that this nest was much more pleasing to the eye.

According to the lesson taught by Liang Baoyu, even if there is no wind on the ground in a clear sky, once you fly into the sky, you can encounter air currents in different directions after reaching a certain altitude.

The direction of these air currents does not change easily, and hot air balloons flying into the sky can take advantage of these air currents at different altitudes and directions to reach their destinations.

Laifu, who is the most proficient in his studies, took out the compass prepared in advance, and secretly wiped his tears while proofreading the direction of the hot air balloon's flight.

For this test flight, Liang Baoyu made up his mind to give the guy who was spying on him all over the world a shock bomb!

The huge hot air balloon will fly towards Chang'an City, and will land on the agricultural experimental field on the bank of the Qujiang River under the gaze of everyone in Chang'an City!

As the altitude climbed, the wind in the sky became more intense, the temperature plummeted, the hot air balloon became swaying from side to side, and the three people in the rattan basket began to work nervously.

The second donkey kept probing to observe the scenery on the ground, and at this moment, even the majestic jade mountain seemed to have turned into a model on the sand table in his eyes, and the houses had become small black dots, and people and other things were completely invisible.

The sound of the wind whistling in his ears covered Laifu's soft sobbing, this guy is still scared to death, but the work on his hand has not been delayed at all, I have to say that Liang Baoyu still knows his little guy very well, otherwise he would never have been sent to the hot air balloon to cause trouble.

Jia San was already a little unsteady in holding the monocular made of wrought copper, and he even felt that his hands were about to freeze with the telescope, and even so, this guy trembled and recorded his observations on the paper he carried with him.

The hot air balloon burrowed into the clouds, the abundant moisture and cold temperature made the three of them covered with hoarfrost, and the situation at high altitude came entirely from Liang Baoyu's account, making them somewhat scrambled to deal with it.

"Ahead...... Is it Chang'an City ahead? ”

"I'll take a look...... It should be...... Except for Chang'an, it is impossible for there to be such a big city on the earth! ”

"This flying ball is so fast! Reduce the flames and prepare to land! ”

The three trembling people controlled the hot air balloon of their first flight and descended towards Chang'an City, and a huge noise sounded on the ground!

Jia San looked down through the monoculars, and he was horrified to find that the defenders on the wall of Chang'an City were actually mobilizing the Eight Bull Crossbows!
