Yu Ling looked up and saw a large white bowl drawing out a golden-red spark, stumbling and floating down, obviously unable to stabilize.

Everyone subconsciously flashed to the side and hurriedly avoided the scene of the incident, leaving only Yuling standing alone, raising his hand to hold the big bowl of flying machine steadily.

"Bang dang. When Yu Ling put the big white bowl on the open space beside him, several young people and girls of the Liyan clan in the bowl were still in shock, looking at him stupidly.

"Ah, Posori!" said one of the teenagers, who suddenly woke up from a dream.

Ji Gu translated at the right time: "He said, Ah, it's you!"

Yuling shrugged and didn't speak, so the difference between a friend and a stranger is only reflected in two words, it's you or you are.

"Tando?" Yu Ling easily remembered the other party's name, after all, when he and Gu Yi came to the gate of Heavenly Flame City before, it seemed that he had only met such a young man from the Liyan clan.

"Mmmmmmmmmm

Nian Yubai couldn't help but stretch out his evil claws and rub the young man's head, but he grinned with his scalded teeth and said bitterly: "No, I thought your hair just looked like flames, but I didn't expect it to be!"

"Hehe," Tando just smirked twice, until the friend next to him reached out and patted him, he suddenly came to his senses, and hurriedly introduced: "Ah, I told you a long time ago, I know many, many foreign friends, what's the fuss!"

The young man completely ignored the surprise in his heart when he saw such a large number of people just now.

A girl from the Liyan tribe whispered, "It turns out that the foreigners look similar to us, and they are completely different from those strange beasts." ”

Everyone can only cry and laugh, and they have the right to be a child.

"Her name is Lilian, it's my cousin, his name is Saiba, it's my good brother, it's almost the same as me before, they all like to wave and wave, but this half a year is completely obsessed with research and can't extricate himself, he has always felt that there is a lot of room for the development of the aircraft, so he tried to make a breakthrough in the load capacity and speed, but I don't know which part went wrong, just now the power system completely collapsed, I almost thought my life was over......" Tando patted his chest, and his heart palpitated.

"What is he talking about, why do I feel like I don't understand it?" Senior Brother Fang asked in a low voice.

"You really don't understand?" Nian Yubai looked serious.

Fang Zijin nodded vigorously.

"It's okay, if you don't understand it, I don't understand it. Nian Yubai replied very unflatly.

"......" Fang Zijin could only turn his head angrily.

Yu Ling glanced at a fine burning crack under the white bowl, and said casually: "Could it be a material problem?" After all, to increase the load capacity and speed, a higher energy conversion rate will be required, which will have a greater load on the material of the aircraft, and the hardness, toughness and melting point must be paid attention to." ”

The thin young man beside Tando scratched his hair in distress and muttered to himself: "It doesn't make sense, considering the problem of power balance, I have replaced the supply energy with a more gentle and stable bloodstone, although the explosive power is insufficient, and it cannot be perfect in terms of flexibility and increase and deceleration, but it can maintain the power output more smoothly, and it stands to reason that it will not cause too much burden on the material...... What's the melting point?"

"Generally speaking, it is the critical point at which a substance is transformed from a solid state to a liquid state, and generally speaking, the cause of transformation is high-temperature burning. ”

Saiba screamed, but it startled the others, only to see him jump off the white bowl, squatted down and knocked on the bottom of the bowl, and suddenly realized: "No wonder! It turned out that the continuous high temperature burned the empty star iron on the edge, and then blocked the output of the energy converter, so I said why was it so good before, why is it suddenly wrong......

The young man's face was full of research fanaticism, and he grabbed Yu Ling's hand excitedly, and said excitedly almost incoherently: "Thank you, thank you, why don't you do research with me, I see that you know more than me!"

"No, actually, I ......" Yu Ling couldn't say any more as soon as he said half a sentence, and when he looked back, everyone moved back two steps in unison, looking innocent that had nothing to do with us.

Nian Yubai also fanned the flames and said, "Ah Ling, you can do it! Although I don't understand what you are talking about!"

Ji Gu said shyly: "Ji Gu doesn't understand very well, is it wrong for me to translate?"

Yu Ling quickly changed the subject and said, "Tando, is Gu Xuan still in Heavenly Flame City?"

"Ah, you're here, you're looking for Big Brother Gu?" Because of what happened just now, Saiba's enthusiasm increased significantly by 10,000 times, and he was very active in taking the lead.

"I just want to ask him something......" Yu Ling was halfway through speaking, when he saw Nian Yubai secretly shrinking behind the crowd, he reached out and pulled him out, and continued: "That, what if we accidentally break the Drifting Fire Boat?"

"Well, I'll see if it's bad, the main direction of my research is the aircraft, and it's okay to repair it. "Saiba is very cheerful.

"If you say...... It's so bad that you can't see the shape at all......"

Saiba was obviously stunned: "You don't mean the kind that falls from the sky and then shatters sexual damage, right?"

"That's right......"

Saiba was silent for a long time before he spoke: "Well, can I ask you something?"

"Huh?"

"I'm curious how you survived......"

Nian Yubai's face was full of sweat in capital letters.

But Tanduo showed off his knowledge and said: "Oh, this is not easy, I heard Brother Gu say that some foreigners can fly, just like our flying machines!"

Who's the same as your flying machine...... Can this kid speak?

"Then why do you fly in a boat of drift?" said the inquisitive Saiba with a puzzled expression.

Tando said triumphantly: "Didn't I say it, flying machines consume energy, and it must be very difficult for them to fly in the sky." ”

Enough! We're not flying machines!

10,000 complaints in everyone's hearts.

"Ahem, so the Flowing Fire Boat is broken, how can we compensate for it, is it expensive?" Nian Yubai asked stubbornly.

"Of course it's expensive, don't you think it's easy to build a flying machine? From the design and construction, the selection of materials, and the specific production and assembly are all very time-consuming and labor-intensive, almost a good Garda takes ten days to make a piece, and many people can't afford this at home. ”

Nian Yubai's cold sweat came down.

"But you don't have to pay," Tando finally added with a big breath, and said with an innocent face: "Anyway, Big Brother Gu sent it to you." ”

Nian Yubai only felt that his hands were itchy, and he even wanted to hit people a little.

"If you want to find Big Brother Gu, I'll take you there now, but he may still be working, why don't I take you to the city first?"
