The sky was clear, and there were three and a half children lying on the roof not far away.

They craned their necks in unison, staring intently at the two big things that were slowly rising in the heavily guarded military battle.

"What the hell is the War Bureau doing?" Zhu Yong asked curiously.

"Who knows, anyway, I passed on my brother-in-law's order, and he wouldn't let me in." Zhang Anshi said.

"True Orders, False Orders?" Xu Jingchang asked suddenly.

"Of course it's fake."

Zhang Anshi rolled his eyes.

"Hey! You see, the ball on the left is starting to dangle! ”

Zhu Yong suddenly patted his two companions hard, and not far away, the balloon sewn from sheepskin really began to tremble violently.

"Bang!"

As the heating process continued, some of the dense stitches at the seams of the sheepskin balloon leather began to be propped up, and then there was a "tearing" cracking sound.

Sheepskin, even if it is a soft tanned lambskin, is leather after all, and compared to textiles, it is still not suitable for balloons. The reason for the emergence of this balloon is that sheepskin rafts are often used as ferries in the north, and they perform very well in the water, so the craftsmen uphold the spirit of daring experimentation, and choose the most cost-effective sheepskin in the leather, rather than cheaper, or other materials with good performance but extremely expensive, under the premise of requiring a large number of high-quality materials.

Leather and textiles are two options, and you must make one of them to try.

This kind of thing, after all, is the first innovation, if you don't take it out and try it, no one knows if the sheepskin will work.

"Ahem, ahem, ahem!"

As the sheepskin balloon began to shake, the craftsman in the hanging basket below coughed violently from the heated smoke for a while, and his body shook violently.

And the rope under the hanging basket also began to tremble.

This rope is just a safety rope used in the experiment, and the experiment of carrying animals has been carried out before, that is, a few cages of animals are put in the hanging basket, and then people help to light the fire, and the ground safety rope is tightly pulled, and when it is lifted off, the hanging basket that is tightly pulled is only one zhang high from the ground, and the person jumps directly on the line.

If it's really time to fly, there's a high probability that this rope won't be bolted. Think about it, how heavy does it take to stretch out a thick rope thousands of meters long? And how effective can it really be?

This sudden situation stunned the craftsmen who were watching around, and when they came back to their senses, they all looked at Ma Gonggong in unison.

Why don't you find a death row prisoner or something, you have to ask the craftsmen to go on it themselves, because most of the manpower and material resources of the Military War Bureau were concentrated, and after several designs and failures, the hot air balloon that was finally rushed out for manned experiments was now only these two finished products, and animal experiments had been carried out before that.

Ma Gonggong's consideration was to let the death row prisoner, even if he trained him, he had to light the fire, and he had to manipulate it, and in a hurry, what should he do if the only extremely precious experimental hot air balloon was scrapped?

The problem is that time is tight and opportunities are limited, and there is no room for such human negligence to squander experimental hot air balloons.

Therefore, in front of the hot air balloon with only two of them, Ma Gonggong still chose not to use death row prisoners, but to give a large number of incentives and rewards for craftsmen to ensure a greater probability of success in the experiment.

Of course, Ma Gonggong is not indifferent to the lives of these craftsmen, this manned experiment, the first is that there is no need to fly too high, the second is that for safety reasons, a straw pile more than one person high is laid as a buffer, and the straw pile is also put in other soft cushions, jumping down from a few feet high, it will definitely not fall to death or seriously injure people, there is a high probability of no good or minor injury, and a small probability of fracture.

Therefore, since it is unlikely that he will lose his life directly, there are not only brave men under the heavy reward, but also a lot.

Huo Fei on the parchment balloon hot air balloon basket is one of them.

Huo Fei struggled to stabilize his figure, pulled the hanging basket, and looked at the sheepskin balloon where the stitches began to disintegrate, his heart was beating suddenly, and his hands and feet were a little weak.

Huo Fei was waiting for the order on the ground, and now the hot air balloon was flying higher than the building, although there were piles of straw below, but whether to jump down or hope that the hot air balloon could stabilize and then descend slowly was a difficult choice for him to make.

At this time, Ma Gonggong, the eunuch of the Palm Seal of the War Bureau, carefully observed the situation of the sheepskin balloon hot air balloon on the left, and he also hesitated a little.

The sewn sheepskin balloon only disintegrated a small piece, and due to the characteristics of the hot air balloon, not to mention this small piece, it was two more pieces, and as long as the main body was stable, it would always float.

But the problem now is that no one knows if there will be a ripple effect.

It's a long story, but it's only a few breaths away.

Just when Ma Gonggong was still hesitating, Jiang Xinghuo made a decision.

"Human life is at stake, let the craftsmen above jump down first!"

Father-in-law Ma next to him wanted to say something, but Jiang Xinghuo said unmistakably: "Let people shout, I'll explain to you later." ”

Ma Gonggong gritted his teeth and shouted: "Shout Huo Fei down!" ”

After Gonggong Ma gave the order, Jiang Xinghuo grabbed his arm, no longer the sternness just now, and explained sincerely: "Gonggong Ma, you can't take chances now, thinking about what if there is no problem elsewhere. The seam of the sheepskin is broken by the heat, and the other is difficult to ensure that it will not be broken, if it suddenly collapses, the hot air balloon falls rapidly, and the person will die, while it can still be maintained, whether it is along the rope or jump directly, the first is to let people land safely, and the second, if it can still float, and then let the hot air balloon be pulled down and landed for inspection. ”

When Ma Gonggong heard this, he knew that the national teacher had no problem with his plans, but he was a little lucky just now.

The person said in a loud voice: "Ashamed, ashamed." ”

"My father-in-law has worked hard day after day, and he has done a good job." Jiang Xinghuo's words were sincere.

For the hot air balloon, no matter what the reason, Ma Gonggong did put a lot of thought into it, supervised the whole process, and contributed people, which is undeniable.

At this time, having received this order, the craftsmen who cared for their companions shouted towards the sky.

"Fly down!"

"Quick, grab the rope!" Seeing this, the old craftsman next to him also hurriedly commanded.

After Huo Fei heard this, he took a deep breath, gritted his teeth, and reached out of the hanging basket, where a safety rope was tied.

No one will choose to jump hard at this height unless absolutely necessary, and it is safer to slide down the rope.

Xu Jingchang, Zhang Anshi, and Zhu Yong, who were watching from the rooftop not far away, were all worried.

"Mother, he won't want to jump, will he?"

"Surely slip down the rope, he's not that stupid."

Zhang Anshi couldn't see the one-person-high pile of straw underneath, and only smacked his tongue.

"If you jump down, I'm afraid you'll break your legs."

Huo Fei's legs were already trembling, and after hearing the old craftsman's words, he tried to stabilize his body, and reached out to pull the rope tied to the side wall of the hanging basket.

Finally, Huo Fei hung on the edge of the hanging basket, and then grabbed the hanging basket with both hands, although he was trembling and sweating, he did not relax at all.

This rope is very strong, not the kind of grass rope that breaks when you pull it, for Huo Fei, as if he had gained some kind of belief, he firmly grasped the rope with both hands, and then slowly slid down.

However, at this moment, losing the control of the person, the flames on the hot air balloon rose and began to rise violently, the hot air balloon not only shook left and right, but also the sheepskin balloon began to make a "poof" sound, which was a precursor to complete disintegration.

At this time, on the ground under the gondola, craftsmen are desperately pulling the rope and pulling the rope of the hot air balloon down in a circle, fighting against the violent rise of the hot air balloon before disintegrating due to the extreme heat inside.

And Huo Fei didn't dare to move and looked up at the bottom of the hanging basket, now the hot air balloon was shaking too much, he couldn't slide smoothly, and he didn't make up his mind to jump directly.

"Jump—don't hesitate, jump down at the straw pile—"

Jiang Xinghuo watched the sheepskin balloon begin to burn, and directly put his hands to his mouth and shouted.

Huo Fei heard Jiang Xinghuo's words, gritted his teeth, closed his eyes, rushed forward, and his hands were loosened downward, and then, after drawing a parabola in the air, it fell to the ground with a bang.

"My mother!"

"Jumped!"

The three teenagers grew their mouths and were dumbfounded.

Huo Fei only felt that his head was dizzy from being hit by the huge impact force, and then his ears were buzzing, he couldn't hear anything clearly, and he couldn't even judge whether he was alive or dead.

I don't know how long it took, maybe it was a moment, or it could be a long time, Huo Fei opened his eyes, and he was greeted by an unfamiliar face and eyes full of worry.

He had been removed from the straw pile, and the parchment balloon had crashed into the clearing a little farther away.

"How? The military doctor came immediately. ”

Jiang Xinghuo squatted down, helped Huo Fei sit up, and then asked with concern.

Huo Fei touched his chest, there was nothing abnormal except for the dull pain, shook his head, and said weakly: "Thank you, the national teacher, I'm fine, but I'm very dizzy." ”

Looking at the other party's heartfelt concern, Huo Fei was a little moved for a while. It is one thing for people to voluntarily participate in experiments based on heavy rewards, but it is another thing for such big people to take their own attention.

Time didn't pass long, Huo Fei jumped down and was stunned for a moment, and was soon carried off the straw pile by the stretcher made of bed boards by everyone, and then he was sober.

The doctor was born in the army, he was waiting not far away, and came over directly to take a look, he was used to seeing the tragic situation of broken arms and legs on the battlefield, at this time, seeing that Huo Fei had no obvious fractures, and he had a pulse, and his internal organs seemed to be very stable, so he said: "Carry it back and take care of it, if the bones are uncomfortable, they will be a little cracked, I will help you deal with it, and you will be able to recover after a while." The pulse is fine, but now I am not sure if the internal organs have been severely impacted, so don't move violently. ”

Jiang Xinghuo breathed a sigh of relief when he saw this, looked at Gonggong Ma beside him, and gave him a look.

The failure of the experiment was expected by him, and the scientific experiment was not smooth sailing, and the important thing was the summary, reflection, and improvement of the experimenter.

Of course, as a decision-maker, Jiang Xinghuo has to consider people's hearts in addition to these.

Although Huo Fei was a little embarrassed when he jumped down, it was thrilling enough, and anyone who was a little more timid might not be able to withstand such a sense of oppression.

Courage is commendable, and it is the time to employ people, and it must be rewarded.

Ma Jing immediately said: "Huo Fei has no fault, the bounty is fifty taels, and the rice is a thousand stones!" ”

As soon as these words came out, the eyes of many craftsmen suddenly became hot.
