Hot air balloons, even in the era of advanced science and technology in later generations, are not completely sure of safety.

Every year or two, there are horrific reports of hot air balloons in the sky lit up in the sky, turning into giant fireballs.

In the Tang Dynasty, the technology of Liang Baoyu's two knives was used to make hot air balloons, and the danger increased exponentially!

However, this is an era when everyone can cut the kite string that binds people in order to find out what is in the sky, and a little sacrifice is not the point in everyone's thinking process.

Regarding the terrifying thinking of this group of Tang Dynasty people, Liang Baoyu can only respect them as a man in his heart, but he will never take the hot air balloon he made.

In Liang Baoyu's design, there is no need to fly too high in a hot air balloon, and the balls are sewn into shark skin.

After being treated by professional craftsmen, the shark skin is extremely flexible, not only very lightweight, but also very airtight, and even in the later generations of technology, shark skin swimsuits are also extremely good equipment.

Even in the design process, Liang Baoyu also took into account the practical application of hot air balloons, the tough and elastic shark skin can completely resist the projectile arrows, and the airtightness can effectively maintain the temperature of the air in the ball.

As for the fuel, it can only be temporarily topped with hot oil, and he has already asked Hongcheng to contact those Hu merchants from the Western Regions, and find a way to buy some oil to rough process and refine it himself, and when the oil is used for fuel, the problem will be solved.

At that time, presumably the craftsmanship and quality of the hot air balloon itself have also met the requirements of passing the test.

But when it was time to start making, Liang Baoyu found that the information he had was not reliable, and many things were completely out of touch with this era.

I have to say that Liang Baoyu's operation avoided the embarrassment of laymen leading insiders, and after repeated trials, the world's first hot air balloon was successfully made in Liangjiazhuang's secret workshop!

"Yongxingbo, your requirements for this hot air balloon are too cumbersome, if it weren't for so many requirements, I'm afraid we would have built this big guy a long time ago!"

After delaying for more than half a month, Hong Cheng felt that he had a reason to complain, and he felt that he had discovered the secret hidden in Liang Baoyu's so-called immortal methods.

Having participated in all the production processes of parachutes, manned kites and hot air balloons, Hongcheng did not see the legendary spells and fairy arts, and the reason why everything can produce wonderful effects is entirely the work of craftsmen.

Take this hot air balloon as an example, in Liang Baoyu's mouth, this is a large Kong Ming lantern, which has long been recorded in some ancient books.

"Lao Hong, you don't take human life seriously, I don't care how others toss the hot air balloon we made, but the hot air balloon we make ourselves must pass the quality test...... You don't want to kill people when you demonstrate in front of Your Majesty's eyes, do you? ”

Hong Cheng shuddered at the thought of the scene of the hot air balloon exploding in the air depicted by Liang Baoyu in front of His Majesty, and obediently stopped speaking.

Unlike parachutes and manned kites, the guy who controls the hot air balloon can already be called a driver, and considering the cost of a hot air balloon, the driver not only has to toss the hot air balloon into the air, but also bring the thing back to the ground safely, so the necessary training is absolutely indispensable.

"Little Hou Ye, it's time for us to change people, this time the villain is really not good, you just let the villain go!"

In the training class taught by Liang Baoyu himself, Laifu cried bitterly, and the whole person was paralyzed on the ground like mud, no matter how he beat and scolded, he was unwilling to get up and listen to the class obediently.

What is completely different is the young offspring two donkeys selected from the auxiliary soldiers, this half-sized son who has no father and no mother and runs to the battlefield of the grassland with his neighbors to beg for a living, since he followed Liang Baoyu to eat and drink well, his size has risen sharply like a wheat tassel!

Now that he pulls it out, even if the greenness on his face can't be hidden, he is already a man who can do things recognized by the Tang Dynasty.

Especially the eyes of the two donkeys, the ghosts, exude curiosity all the time, and most young people, this guy is full of energy and exuberant curiosity with nowhere to vent, before jumping down with a parachute on the eagle's beak cliff, it is the second donkey that makes the most trouble!

Therefore, this training of hot air balloon drivers, the second donkey was successfully selected.

"Uncle, why don't you let Brother Fu go, I can do it alone......"

"Shut up! Dog-like things don't fight, really when this thing can be controlled by anyone? There are so many people in the Tang Dynasty who are not afraid of death, but if they let out a little rumor, those who are willing to be drivers can be lined up from our mother's Zhuangzi to Chang'an City, why did this lord pick the two of you, don't you have any points in your heart? ”

In the face of Liang Baoyu's scolding, the second donkey wisely closed his mouth.

Brother Laifu, it's not that my brother doesn't help you intercede, it's really that my uncle's temper is strong, and you're not the only one who will be beaten if I talk more!

Facts once again proved that the arm could not reach the thigh after all, with the beating and scolding all the way, the crying Laifu finally completed the driver training, and even because this kid knew a few words, the final final exam was better than the results of the second donkey......

"Don't panic when you get to the sky later, just follow the operations you usually train on the ground, and the veterans in the Zhuangzi will chase you all the time on horseback, and they will definitely not lose you."

The last inspection before the hot air balloon lifted off had just been completed, and Liang Baoyu began his pre-war mobilization, "Second donkey, as long as you can become a qualified hot air balloon pilot, the house in Dunhuafang will be divided into one for you!" ”

The power of the tube building in Chang'an City is extraordinary, and the two donkeys who have never been able to distinguish suddenly became serious, there is a house in Dunhua Fang, which is the most show-off product for the soldiers who have stayed on the grassland, as an auxiliary soldier, the two donkeys never dared to dream of such a good thing!

"Laifu, as for your lord who made it clear before, the eldest girl in the Zhuangzi who didn't go out, the widow who didn't have a man, no matter which one you look at, I will let the housekeeper personally come to the door to tell you the matchmaker!"

Laifu is different from the second donkey, if you want this guy to risk his life to do things, unless it is related to the vital interests of Liang Baoyu or the Liang family, otherwise he can only use marriage as a bargaining chip, "You kid will work hard for me, don't lose the face of this lord, if you get married, the old Zhuangzi will build a small courtyard for you!" Well, let's light the fire! ”
