Inside the ninth chamber was a wooden plane, the most primitive kind of plane that could take people into the sky. Although Zhang Nan had not seen it with his own eyes before, Zhang Nan was still sure that the plane was the first generation.

But just this plane made of wood had already made Zhang Nan break out in a cold sweat.

"Is it hard to have a traverser before you?" Zhang Nan asked himself in his heart, the final answer was yes, otherwise the appearance of this wooden plane would not make sense at all.

"Mo Zu, can you tell me about the origin of this thing?" Zhang Nan asked cautiously. If the owner of this wooden plane had already burped, then Zhang Nan would have nothing to fear, but the thought that someone might be the same traverser as him, and it was very likely that he would live in the same dynasty as him, made Zhang Nan still very afraid.

"This, this is the result of the painstaking efforts of our ancestors in Momen, as for when it was handed down, I don't know very well the old man, since I was born as an old man, I have seen this thing." Mo Zu looked at the wooden plane and said.

After speaking, Mo Zu also stepped forward and gently stroked the wooden plane, as if the plane had life.

"Didn't you say that only the heirs of the Mo family could look at this thing? Is it difficult that you will be a successor in one life? Zhang Nan was a little puzzled.

"Hey, I set this rule, and naturally it's up to me to decide." Mo Zu said with a smile.

After hearing this, Zhang Nan was speechless, but Zhang Nan still got useful information from Mo Zu's words, that is, the age of this thing must be different from his own, and he doesn't have to worry about having a time-traveler and go out of the same dynasty as himself, after all, no one can live more than 100 years and almost 200 years old.

"Although I don't know what this thing is, old man, or when it was handed down, it is recorded in the history books. The old man thought that this was the wooden bird made by Mr. Luban that could fly for three days and three nights without landing. Mo Zu looked at the wooden plane and said seriously.

As soon as Zhang Nan heard Mo Zu say this, he looked at the wooden plane again, it was indeed very similar.

There is such a record in the historical book "Mozi Lu Wen": "The male loser cuts bamboo and wood to think that he is a magpie, and he flies into it, and it does not fall for three days." That is to say, the wooden bird made by Luban can fly high in the air with the wind and not land for three days.

Of course, Zhang Nan knew that it must be an exaggerated rhetoric to stay for three days, because it was impossible for this wooden plane to fly for three days without coming down, but this wooden plane could fly, and Zhang Nan felt that it was still possible.

And "Mozi. According to the record in the Lu Wen Chapter, nine times out of ten it may be this thing, but I don't know what the reason is, this thing is missing.

Zhang Nan didn't bother to delve into it anymore, anyway, this thing wouldn't affect him anything.

"Listen to you, you seem to have seen this thing, huh?" Mozu asked.

Zhang Nan thought about it, but decided to tell the truth, so he said: "That's right, I've really seen this thing." ”

Hearing Zhang Nan say that he had seen it, Mozu did not ask Zhang Nan where he had seen this wooden plane, but asked excitedly, "Oh?" So what's this thing called? Can it really fly for three days and three nights without landing? ”

"This ...... I think it's an exaggeration that this thing can fly for three days, but I think it shouldn't be a problem for this thing to fly. Zhang Nan scratched his head and continued: "As for what this thing is called, we will pass through a gate and call it an "airplane". ”

"Airplanes?" Mo Zu slowly chewed on the name in his mouth, and after a while, Mo Zu clapped his palms and said: "The name of the plane is good, the ingenuity that can fly in the sky, it is indeed a very appropriate name to call the airplane." ”

"By the way, boy, do you really think this thing can fly?" Mo Zu asked as soon as he spoke.

"This ...... It's been so long, I'm not sure, but I personally think he can still fly. And Mozu, you don't want to call the boy, if you want, just call me a clear spring. Zhang Nan stepped forward and flicked the propeller in front of the wooden plane with his hand, and found that the propeller could rotate, and it was only a little laborious, as long as the dust was removed and then oiled, Zhang Nan felt that this thing still had the possibility of flying.

"Okay, Qingquan, old man, I have a reluctant invitation today, and I don't know what you think?" Mo Zu thought about it, but decided to say what was in his heart.

As soon as Zhang Nan heard that Mozu had a reluctant invitation, he immediately raised his vigilance, because the lessons of history told Zhang Nan that every time someone said a reluctant invitation to himself, he was either selling his daughter to himself or his daughter to himself.

"Mo Zu, you talk about it first, I will depend on the situation." Zhang Nan said.

"Then the old man, I said cheekily, Qingquan, since you have seen this thing, and you know that this thing can fly, then can you stay in this mountain for a little more time, and let this plane fly again, you know, Momen is now in decline, there is no treasure that can suppress Momen, that is, I, the old man, still have a breath, this Momen has not fallen apart, if there is no ingenuity that can suppress Momen, old man, I am afraid that after a hundred years, Momen will become a plate of loose sand." Mo Zu sighed and said.

"This ...... Do you want me to stay here and fix the plane? Zhang Nan said with a strange expression.

"That's right, that's what it means."

"What if I can't fix this thing, after all, I'm not very good at Karakuri." Zhang Nan scratched his head and said, if you want to let Zhang Nan get a plane out, then Zhang Nan has no problem, as long as Zhang Nan is given enough money, Zhang Nan can even change the satellite out of the system, but now let Zhang Nan repair the plane, this Zhang Nan can not be guaranteed, after all, Zhang Nan himself is a half-ass, especially this kind of high-end machinery, even more ignorant.

"If you don't repair Qingquan, then I will recognize the old man, but I still want to see the treasure of our Momen from ancient times to the present flying again before entering the ground." Mo Zu said with a look of yearning.

"Well, it's not impossible for me to repair the plane." Zhang Nan said.

"Oh? So you agree? Mo Zu said with a look of surprise.

"It's not impossible for me to stay in the mountains for a few more days, but I have to send a letter out, or my wife will worry about me." Zhang Nan said.

"It's simple, as long as you're willing to help Momen, you can send a letter out now." Mo Zu said with a smile.
