There was a wooden plane parked in the ninth secret room, which was the most primitive plane that could bring people into the sky. Although Zhang Nan had never 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 has already shocked Zhang Nan and sweated.

"It's so difficult that there are time travelers before me?" Zhang Nan asked himself in his heart. The final answer was yes, otherwise the appearance of this wooden plane would not be able to explain at all.

"Mo Zu, can you tell me about the origin of this thing?" Zhang Nan asked carefully. If the owner of this wooden plane had turned aside, Zhang Nan would not be afraid, but when he thought that someone might be a time traveler with him and was likely to live in the same dynasty as him, this made Zhang Nan still very scared.

"This, this is the result of the hard work of our ancestors in Mo Sect. As for when it was passed down, I don't know very well. I have seen this thing since the old man was born." Mo Zu said as he looked at the wooden plane.

After saying that, Mo Zu walked up and gently stroked the wooden plane, as if the plane had life.

"Didn't you say that only the descendants of the Mo family can see this thing? It's so difficult that you will become the descendants in your life?" Zhang Nan was a little puzzled.

"Hey, I set this rule, so of course I will make the final decision." Mo Zu smiled.

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 that of him, so he doesn't have to worry about time travelers coming into the same dynasty as him. After all, no one can live more than one hundred and almost two hundred years old.

"Although I don't know what this thing is, and I don't know when it was passed down, there are records in historical books. The old man thinks this is the wooden bird made by Mr. Lu Ban that can fly for three days and three nights without landing." Mo Zu said seriously as he looked at the wooden plane.

When Zhang Nan heard Mo Zu say this, he looked at the wooden plane again, which is indeed very similar.

There is a record in the historical book "Mozi·Luwen Pian": "Gongshuzi cut bamboo and wood and thought it was a magpies, and he flew it and did not fall for three days." That is to say, the wooden birds made by Lu Ban can fly high altitude by wind and do not land for three days.

Of course, Zhang Nan knew that not getting off these three days was definitely an exaggerated rhetoric, because it was impossible for this wooden plane to fly for three days, but Zhang Nan thought it was OK to fly this wooden plane.

The records in "Mozi. Luwen" are probably probably this thing, but I don't know why it is gone.

Zhang Nan was too lazy to go into it further, anyway, this thing would not affect him.

"I heard what you mean, you seem to have seen this thing?" Mo Zu asked.

Zhang Nan thought about it and decided to tell the truth, so he said, "That's right, I have indeed seen this thing."

When he heard Zhang Nan say he had seen him, Mo Zu did not ask where Zhang Nan had seen this wooden plane. Instead, he asked excitedly: "Oh? Then what is this thing called? Can it really fly for three days and three nights without landing?"

"This... I think it must be an exaggeration to fly for three days, but I think it shouldn't be a big problem for this thing to fly." Zhang Nan scratched his head and continued: "As for what this thing is called, we travel through a door and call it "airplane."

"Airplane?" Mo Zu slowly chewed the name in his mouth. After a while, Mo Zu clapped his hands and said, "The name of the airplane is a good one. The trick to fly in the sky is indeed a very appropriate name."

"By the way, kid, do you really think this thing can fly?" Mo Zu asked.

"This... I'm not sure about it for so long, but I personally think he can still fly. And Mo Zu, don't call me a boy. If you want, call me a clear spring." Zhang Nan walked up and used his hand to dial the propeller in front of the wooden plane. He found that the propeller could rotate, and it was just a little effort. As long as you remove the dust and add oil, Zhang Nan felt that this thing could still fly.

"Okay, Qingquan, I have a heartless request today, and I don't know what you think?" Mo Zu thought about it and decided to say what he said.

When Zhang Nan heard Mo Zu's reluctance request, he immediately became vigilant, because the historical experience and lessons told Zhang Nan that every time someone said a reluctance request to him, it either sold his daughter to him or promoted him to himself.

"Mo Zu, please tell me first, I will depend on the situation." Zhang Nan said.

"The old man said with a shameless face, Qingquan, since you have seen this thing and know that this thing can fly, can you stay in the mountains for a while and let the plane fly again? You know, the Momen is now in decline, and there is no treasure that can suppress the Momen. That is, the old man, I still breathe a sigh of relief, and this Momen has not fallen apart. If there is no trick to suppress the Momen, I am afraid that the Momen will become a piece of loose sand after a hundred years." Mo Zu sighed and said.

"This... do you want me to stay here to repair the plane?" Zhang Nan said with a strange expression.

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

"What if I can't repair this thing well? After all, I'm not very good at maneuvers." Zhang Nan scratched his head and said, "If you want Zhang Nan to get a plane out, then Zhang Nan will have no problem. As long as you give Zhang Nan enough money, Zhang Nan can even replace the satellite from the system. But now, Zhang Nan can't guarantee that Zhang Nan will repair the plane. After all, Zhang Nan himself is just a half-baked person, especially such high-precision machinery, and he knows nothing.

"If you haven't repaired the Qingquan well, I will accept that old man, but I still want to see the treasures that have been passed down from ancient times to the present in our Momen again before entering the soil." Mo Zu said with a look of yearning.

"This, it's actually not impossible to ask me to repair the plane." Zhang Nan said.

"Oh? Do you agree to that?" Mo Zu said with a look of surprise.

"It's not impossible to let me stay in the mountain for a few more days, but I'm going to send a letter, otherwise my wife would have to worry about me." Zhang Nan said.

"This is simple. As long as you are willing to help Momen, you can send a letter out now." Mo Zu smiled.
