The transport plane continued to fly smoothly in the air, a few hundred meters above the ground at a height of enough to overlook the ground. There were eight or nine pairs of eyes on the transport plane looking down on the ground, and if there was a town, they would be able to spot it immediately.

Ye Cheng, Bei Mao and Bai Yingping gathered around to carefully observe the county map.

This county map can actually help the people of Manlan Kingdom walk in this moving city, so Ye Cheng firmly believes that there is something in the county map that Manlan Country can understand, and they haven't figured it out for a while.

Now, as long as you figure it out, you will definitely be able to reach the capital or the place where the moon is marked through the county map.

But Ye Cheng had been staring at the county map for almost half an hour, and he still didn't have a clue. He felt more and more impatient, scratching his head with his hands, there was really nothing he could do.

Yin He, who was sitting against the wall of the fuselage, saw Ye Cheng like that, and she smiled happily.

Because Yin He was sitting next to the fuselage wall behind Ye Cheng, he could hear Yin He's snickering laughter. So Ye Cheng slowly turned his head to look at Yin Hao and asked, "What are you laughing at?" ”

Yin Hao smiled: "The three of you have watched for most of the day, and you can't see a clue. Why not try something else, such as boiling it over fire or soaking it in water?"

A word to wake up the dreamer!

What a word to wake up a dreamer!

Yin He's words gave Ye Cheng a big hint, and he thought of it. In the past, the ancients did not want people to see the written words, so they would use some special ink, and when the ink dried, the handwriting would disappear, and the handwriting sprinkled on the paper would appear again.

Right! That's it.

Ye Cheng was ecstatic, he laughed at Yin He, and said, "Thank you Yin Shopkeeper for reminding me."

After thanking him, Ye Cheng turned his head and held the county map in both hands to check it again. This county map is made of cowhide, presumably the method of using water is not very effective, so you can only try it with fire.

Fire Fire Fire ......

Ancient flints and steels were not very convenient, so only modern lighters remained.

Ye Cheng remembered that one of the pilots was a smoker, and there must have been a lighter for smoking. So he quickly got up and ran towards the cockpit.

Seeing Ye Cheng running away in a hurry, Bai Yingping was a little worried, so he asked, "What's wrong?" What do you think of? ”

"I'll borrow a fire," Ye Cheng replied as he ran.

But Ye Cheng's mouth full of modern sentences made Bai Yingping, who had lost his memory and become an ancient person, confused. Bai Yingping looked back at Bei Mao opposite with a confused expression, and said, "What does it mean to borrow a fire?" ”

Beimao didn't know either, just shook his head.

At this time, Ye Cheng had already run to the cockpit to borrow the lighter from the pilot, and then ran back. After returning to Bai Yingping's side, he hurriedly ordered: "Come, help me pick up the county map, let me burn it with fire"

Bai Yingping and Bei Mao did not hesitate, the two of them grabbed one side of the county map with both hands and raised it high.

Then Ye Cheng opened the lighter cover, and the thumb of his right hand slid the wheel-shaped small flint, and the sparks generated by the small flint ignited the gas, and then the gas outlet ignited a thumb-sized droplet-shaped flame.

This lighter is the kind of retro style.

Ye Cheng put the lighter under the county map with his right hand, and used the thumb-sized flame to lean against the bottom of the county map. Because the prefectural map is made of cowhide, there is no need to worry about it being burned.

The flames burned below, and Ye Cheng looked at the county map to see if there were any changes.

Sure enough, words appeared wherever the fire had been roasted.

It did take some time to bake a one-meter-by-zero-and-a-half-meter cowhide county map with the flame of this little lighter, but fortunately, the whole cowhide was baked, and now the county map is a little warm but not hot.

"Put it down," Ye Cheng commanded.

Hearing the order, Bei Mao and Bai Ying slowly put down the county map.

Ye Cheng lowered his head and looked seriously, now the text appeared on the county map, which was much clearer. None of the town signs now have their names underneath, and the blue lines on the rivers are also marked. It's just that he couldn't understand the meaning of these crooked words, so he skimmed over.

He pointed to the crescent moon sign on the county map and asked, "Brother Beimao, what is written on this?" ”

"The Source of the Moon?"

Beimao looked at it, muttering in his mouth. Before answering Ye Cheng's question, he thought about it in his mind. He was also puzzled by the words 'source of the moon'. I really couldn't figure it out, so I slowly answered Ye Cheng's question: "There are three words on it: "There are three words on it."

The Source of the Moon?

Ye Cheng also fell into a deep thought after hearing this.

At this time, Yin He's calm voice came from behind Ye Cheng again: "Have you heard a story?" Legend has it that the Manlan country is scorched by the sun all year round, drought and little rain, and it is difficult to survive, so the people here hate the sun very much. But there was a place where water suddenly gushed out on a dark night. This water gave the people the opportunity to multiply. It's only at night that this water source bubbles out, and slowly that place is called the source of the moon.

With the availability of water, the population multiplied and became more and more numerous, and they had to move out. However, after moving out, you will not be able to enjoy the source of the moon.

I think the river under the desert that you found must have been made by the people. Only in this way can we continue to live on water and not be scorched to death by the sun."

After finishing the story, Yin Hao looked at Ye Cheng with a charming smile and continued, "How is it? Did this story help you?"

Ye Cheng looked at Yin He in surprise and looked at him in a daze.

The story did help a little, and it made him figure things out. Previously, Ye Cheng thought that the moving sand dunes meant an underground river, but now it seems that this is not true. Judging from the story that Yin He said, the moving sand dunes should refer to the people scattered from the Moon Source.

The people of the Moon Source are moving outward little by little, like sand, and they can survive wherever they go. This should be the analysis of moving dunes.

If the people of Manlan had migrated from the source of the moon, they would have believed that they would be buried back to their homeland when they died. This means that no matter where you move to, you will eventually return to the starting point.

If this is the case, then Ye Cheng understands that the elixir is at the source of the moon.

After thinking of this, Ye Cheng came to his senses and immediately turned his head to look at the county map and looked around. But the crooked text was too difficult to understand, so he turned to Bei Mao for help: "Brother Bei Mao, please see if there is a direction provided on this, tell us how to fly to reach the source of the moon?" ”

"Okay, I'll see"

Bei Mao didn't ask too much, he looked down at the county map first. After looking at it carefully, he probably knew the direction. He replied, "Judging from the direction marked on the county map, the source of the moon is in our southwest direction."

After hearing the direction, Ye Cheng immediately turned his head to look at the cockpit and shouted: "Turn your head quickly, fly to the southwest, and fly as fast as possible."

"Yes"

Three pilots shouted at the same time.
