I do research in ancient times

Feng Kai and Clay naturally had no objection to what Ning Fei said, only Nada frowned.

"ferry?"

The middle-aged craftsman scratched his head.

"Are you here by boat? Is it because the Tuotuo River is flooded this time?"

Ning Fei didn't answer him.

Ning Juzi is brainstorming the structure diagram of the hot air balloon.The altitude of Sanyazi Mountain is almost the same as that of the opposite side. It is impossible for paragliders to fly over it, and it depends on the hot air balloon that can lift into the sky.

The sails hung on the ship were naturally not big enough.It's not good enough, but Miss Pinghua is very caring. Hearing that Ning Juzi wanted to try the boat, she even stayed up all night to weave a wide cotton cloth to make a canvas.This cloth is woven according to the scale of Karak, the squid boat can't use that big, and the extra is put in the bottom of the warehouse for backup.

Pinch your fingers and do the math, it's almost enough.Anyway, you don't need to fly for a long time, and you can complete the mission successfully if you can cross the Tuotuo River Valley.

"Can you weave rattan baskets?"

Ning Fei asked Clay.

Clay nodded.

"Yes, the uncle in the carpentry class taught me, I can make it very fast."

"Great."

Ning Fei nodded and gestured with her arms.

"I need a basket about this size, the stronger the better. How long will it take to be able to carry the weight of four people in the air?"

Hearing him ask such a question, the child was a little embarrassed.

"Brother Fei, if you want to carry people, the rattan must be soaked in oil, and you must choose a strong old rattan, which is not available here."

"That's it."

Ning Fei gave up decisively.

"It's not safe to use ordinary rattan. We have to hang hundreds of meters in the air, which is too dangerous."

"What? Suspended? What rice?"

Ning Fei was taken aback, then realized that he was used to the metric system, so he changed his mind.

"It's 300 feet, and it's 200 feet in the air."

He pointed to the top of the mountain that had gone some distance away.

"This mountain is about 200 feet long, right? If you want to fly over, don't you have to hang 200 feet in the air?"

As soon as these words came out, not only Nada, but the other two people present also stopped.

"What? Brother, you said we want to fly?"

Clay's eyes widened in shock.

"Fly...does it mean to fly to the sky? How to fly? We don't have wings!"

Feng Kai was very calm, only surprised for a moment before returning to normal, and asked Ning Fei what he needed to do.

"It's true, brother Muye, please."

Ning Zazi thought about it for a long time, but still felt a little hard to say.

"You... can you do needlework?"

After much deliberation, he still had to rely on Clay and Feng Kai to sew the umbrella cover.

He wanted to burn umbrella rings, research flamethrowers, and transform the fish boat into a substitute for rattan baskets. All of these required him to do it himself. The time was already tight, and it was impossible for him to do it alone.

But brother Muye, brother Muye is doing needlework...

Ning Sawzi imagined that scene for a moment, then shivered, feeling a little guilty.

General, the hand holding the sword, let people use herringbone needles to sew cloth, would they be happy?

Unexpectedly, Feng Kai nodded very simply, without any sense of reluctance.

"I've made hanging nets, so there should be no problem."

Oh?

Hearing what he said, Ning Zazi's eyes lit up.

hanging net?That's handicraft work, I didn't expect Brother Mu Ye to do it too?

As if seeing his doubts, Feng Kai smiled with gentle eyes.

"When I was young, I was hunting outside the customs with my uncles. It was common for people to hang nets and dig traps. All the brothers in the family knew how to do it."

Oh, it turned out to be a hanging net for hunting.

Anyway, it's not too much difference, just know how to use a needle and thread.

"Hey, hey master, master, what do you mean by flying? Are we going to fly into the sky?"

Nada is still jumping around.

Ning Fei turned her head and spoke calmly.

"Yes, by heating the air, it is possible to lift off briefly."

"Master Nada, we are going to fly to Nanshibu on the opposite side like this. It may be life-threatening. Do you want to come with us?"

When he asked this, Nada froze for a moment.

"You...you didn't plan to take me with you?"

He was like a leaky ball, and his spirit suddenly froze, which was rather pitiful.

"No."

Ning Fei patiently explained to him.

"Because it is dangerous to climb the mountain, but we have reasons to go, so we have to take the risk."

"But you, you are originally from this place. Although you seem to be in some trouble now, it is better for you to decide whether to risk your life and follow us."

Nada thought for a while, then pointed to the sky.

"Crossing the mountain you are talking about, is it really flying up the sky? The kind with your feet hanging in the air?"

"Fire the air... what is the air? How to burn it?"

"It's hard to say the exact principle, and we have to make adjustments as we go, and only when we're sure it works will we lift people into space."

Ning Fei answered very frankly.

"But after all, there is still a risk, and it may fall."

"I'm going with you."

Nada scratched the back of his head and laughed dryly.

"I'm a Tuhe, and I'm a different tribe from the Haryu people. If I didn't follow Shimen, I wouldn't come to the Xihu people's territory."

"A few years ago, Hexa forced us to forge swords, and agreed to manage mines and coal. In the end, the ore was the worst, with sulfur mixed in it. All the brothers and sisters ran away to death, and I was the only one left."

"I wanted to leave a long time ago! But Sakuru always finds someone to watch me, and I can't even pass the gate. He forced me to teach his craftsman the skills of the craftsman of heaven, otherwise he will not let me go back to my hometown!"

Having said that, Nada wiped his face, and his voice suddenly sank.

"I'm alone, and I don't have to go back, but I can't betray my master!"

"Sakulu forced half of my master to death. Tian Jiangren can't work for Sakulu, and can't pass on his skills. This is the master's last order. Even if Nada dies, he can't disobey it!"

"so……"

Nada reached out and grabbed Ning Fei's shoulder.

"I'll go with you, at worst it's my life! Flying is a rare thing, and dying in the sky is better than being tortured by Sakuru!"

He spoke excitedly, but Ning Zazi's heart moved because of a certain point in his words.

"You have sulfur here?"

He touched his chin.

"Is there any saltpetre?"

"Yes, I have."

Nada didn't understand what he meant by asking this, but he pointed to Siyazi Mountain honestly.

"There is a saltpeter mine on the top of the mountain. But no one uses this thing except Dawu's alchemy pills. Why do you want this?"

"Something useful."

Ning Zhizi smiled and didn't say much.

He had a hunch that perhaps the barbarians of Hexa would return soon.

Just like what the barbarian boss said, Hexa cannot be bypassed, and there is a high probability that the matter will not end here.

If it is torn apart, Siyazi Mountain is steep and easy to defend but difficult to attack. Using gunpowder to create some obstacles may delay some time.

"Go to work!"

Ning saw clapped his hands, and asked Nada to find a ruler, and arranged for Clay and Feng Kai to pull the squid boat up the hill, while he started to calculate various data for cutting the canopy.

He didn't stop when the canvas came up, and quickly completed the measuring and cutting of the fabric.

The next step is to splice these cut parts together.There were fishing nets and fishing lines on the squid boat. Feng Kai and Clay dismantled the fishing nets and quickly started to rush to work.

"Master Nada, I want to burn an iron ring. I wonder if it's convenient for you?"

Ning Fei turned to Nada and said.

"Convenient and convenient, there is no difficulty in burning rings, iron bars are ready-made."

Nada readily agreed.

"Master, what kind of ring do you want? Just tell me, and I'll burn it for you."

"About this big."

Ning Fei drew a circle on the ground with a wooden stick.

"Try to be as round as possible, and the welding points should be strong, and then burn an iron furnace with a bottom support, and the extension is larger than the previous iron ring. This split firing can be done, as long as the size is determined, and then installed. There are slides on the outside of the furnace, and there are buckles on the top to ensure stability, do you understand?"

He drew while talking, and Nada watched it very seriously.

He pondered for a moment and nodded.

"No problem, I can burn it for you at night."

Ning Fei raised an eyebrow.

No problem, no problem, no problem? !

His design structure is quite complicated. Nada said that it can be completed in the evening, isn't he bragging?

Nada is really not bragging.

When the sun went down, the blacksmith's furnace, which had been burning for half a day, finally extinguished the flame.The wind on Sanyazi Mountain was very hard, and the cooling speed of the iron parts was much faster than that of Niubei Mountain. In less than half an hour, Nada started to assemble the flamethrower.

Ning Fei went over to take a look, and couldn't help being surprised.

This master Nada is really a talent, he even understood his design drawings in the first time, and even made some adjustments to some details!

For example, a baffle to prevent the flame from being extinguished was added, and the coal-filled furnace chamber was made thinner and easier to slide.

This design, in fact, already has some prototypes of pistons!

Seeing him look over, Nada was a little embarrassed.

"I... I just thought I could add something, and I don't know if it's right? But it doesn't matter, this thing can be disassembled, and it won't delay your original idea at all."

"not bad."

Ning Fei nodded again and again, and for the first time seriously looked at the middle-aged man in front of him.

"Master Nada seems to be very good at iron mechanisms? Is this the skill of the craftsman?"

Listening to his question, Nada shook his head.

"Our master doesn't make this, the craftsmen of heaven only forge swords, and controlling fire is a unique skill."

Speaking of this in the past, Nada was always proud, but now that he met Ning Fei and his party, he felt that he had no confidence.

Not to mention the wavy patterns and golden threads that can't be figured out no matter what, he saw this young man burning stones and frying ashes in his workshop this afternoon. He thought he was also preparing to fly into the sky. There is a little thunder!

"The saltpeter powder is still not dry enough."

The boy with ashes on his face stood up from behind the stone, and saw a small hole in the ground in the distance, with a dissatisfied expression on his face.

"The sound is quite loud, but the power is average. Isn't this just a bigger second kicker?"

Nada was frightened silly.

He has experienced quite a few things in his life, but he has never seen someone mix several kinds of ore powder casually, and when he ignites it, it will make a sound like thunder!

As if thinking of something, Nada's eyes were filled with fear and awe.

"This... Master..."

He swallowed, and stammered tentatively.

"The villain didn't know your identity before, so it was offensive. You...you...could you be... the legendary Huolei Holy Witch of the Xihu people?"

Ning Shaozi: ... What?
