ancient female doctor

Chapter 261 Teaching Guide
The cloth ball of the hot air balloon was blown up again by the windmill, and the stones hanging around the rattan basket were also tied up again.

Qingzhu called all the eight people who were going to fly next, and this furnace of oil could burn for more than an hour, but because of time constraints, Qingzhu didn't plan to start a new life after it was extinguished for the last time.

"Look, this position is the oil outlet of the stove. Only when this valve is turned open, the oil in the stove will be sprayed into the burning plate. Otherwise, no matter how you ignite the fire, there is no way to ignite it." Qingzhu said , and smiled at the female soldier standing next to her who had initially chosen to fly.

The female soldier blushed immediately, but Qingzhu's smile was not malicious, so she didn't feel that Qingzhu was laughing at herself.

It's just that she felt ashamed and ashamed in her heart, so she listened to Qingzhu's explanation more carefully.

He pointed out the oil outlet valve of the stove to everyone, and Qingzhu asked everyone to twist it by themselves.However, everyone's speed is very fast. Basically, as soon as they are unscrewed, they will be unscrewed and closed again immediately, so there is not much kerosene stored in the burning plate.

"Come on, give me the torch." Qingzhu said after everyone had tried.

Qingzhu took the torch, lit the burning plate, waited for the fire to ignite, then passed the second half down, and then unscrewed the oil outlet method.

Because Qingzhu made a suggestion early in the morning, some simple scales were engraved on the oil valve. Qingzhu said while unscrewing the valve: "Everyone has unscrewed the valve just now, so I lit the fire. It takes a while to unscrew the valve again, if it is the first time to ignite, just turn the valve to the minimum scale directly."

While talking, Qingzhu pointed to the scale on the top of the valve with the thin stick in his hand, and after drawing a semicircle with the thin stick, he continued: "This valve is both an oil outlet valve and an oil control valve. From left to right, each scale sprays oil The amount of oil coming out is different, the farther to the right, the greater the amount of oil.”

"Generally, when the fire is just ignited, the valve is opened to the minimum, and after the fire is lit, the valve must be opened to the maximum immediately, so that the hot air can fill the cloth ball on top of us more quickly. After the hot air is almost completely filled, we Then you can cut off the stones on the edge of the rattan basket."

"Medical Officer Xia, how can we judge whether the heat in the cloth bag has filled the entire cloth ball?" A female soldier asked while looking at the green bamboo while touching the hemp rope hanging from the top of the rattan basket.

She had watched Qingzhu lightly tugging on those hemp ropes during the whole ignition process.

"That's a very good question." Qingzhu looked at the female soldier who was asking the question approvingly, and said, "That's why I asked you to surround me now, we can pass the thread on the hemp rope connected to the cloth ball." Strength, to judge whether the heat inside the cloth ball is basically full or not."

As Qingzhu said, she gently pulled the hemp rope with her hands.

Seeing Qingzhu's movements, the others couldn't help stretching out their hands, wanting to pull them.

However, Qingzhu immediately stopped them: "Don't worry, it's still early, the four people standing in the first row before stand in the rattan basket first, I will let you all feel it later."

As he said that, Qingzhu moved his body away slightly, so that the first group of people, including Princess Anle, could step on the step stool to enter the rattan basket.

After the four of them got into the rattan basket and stood in the four corners of the rattan basket, Qingzhu had someone tie hemp rope around their waists, and the other end of the hemp rope was of course also tied to the rattan basket.

As soon as Princess Anle said the word 'I don't', Qingzhu put on a hard face, thinking about what she had promised Qingzhu earlier, Princess Anle could only swallow the rest of the words, and let others His waist was tied up.

However, Qing Zhu didn't ask someone to tie a hemp rope for her.

Because as long as there is no operating error, or the hot air balloon suddenly breaks down, the rattan basket is actually quite safe.Tying the hemp rope is just to make them feel more secure in their hearts.

If the operation is wrong, or the hot air balloon suddenly breaks down for some reason, the hemp rope will be of no use at all.

Seeing that several people were tied with hemp ropes, Qingzhu continued: "From the hemp ropes hanging the rattan baskets, we can judge many things. The first thing to judge is whether the windmill can stop, of course. , this can be roughly estimated based on time.”

"As you have seen before, you should basically understand when the blower can be stopped, but here, I still want to say it again. Generally, we can stop the first blower after lighting the fire and opening the valve to the maximum. Then half After a quarter of an hour, the second and third blowers can be stopped. The last one can only be stopped until you feel an upward force on the hemp rope."

Speaking of this, the time was just about right, Qingzhu asked everyone to stop the last blower, and at the same time motioned everyone to gently pull the hemp rope with their hands to feel the strength from the hemp rope.

Although everyone is more curious, but because Princess Anle is there, they are still more cautious. After Princess Anle pulled the hemp rope, the others gently pulled the hemp rope to feel the strength, and then stopped moving again. Just waiting for the next step of guidance from Qingzhu.

It's not enough for others not to pull, but it doesn't mean Princess Anle doesn't pull. When she felt the upward force from the hemp rope for the first time, she would pull it from time to time.

Qingzhu looked at it, and didn't stop it, but nodded approvingly, and said: "Well, we rely on the feeling now, you should feel it more, but the movements should be a little lighter, and we don't want everyone to do it together, at the same time Just pull and pull, one by one in turn.”

Once they got the green bamboo, the others became unrestrained and took turns pulling up the rope.

Because of the first experience, when Qingzhu reckoned that the time was almost up, and was about to pull it by himself, Princess Anle, who had just loosened the hemp rope, suddenly said, "Qingzhu, try it, now this is Isn't it almost there?"

Hearing the words, Qingzhu nodded, and said: "It should be about the same." After speaking, Qingzhu also pulled the hemp rope, then looked at everyone and said: "Come and experience it quickly, and then you are not the one who needs to learn in this round. Just get out of the way."

After everyone got out of the way, Qingzhu said to Princess Anle: "Princess, please cut off the hemp ropes that are connected to the stones."

As soon as Qingzhu finished speaking, Princess Anle pulled out his dagger, and with a few brushes, he cut off the hemp ropes tied to the rocks around the rattan basket, more than twice as fast as Qingzhu.
