If Xia Lan is more concerned about the situation in the underground palace, then Jun Qianqian is definitely more concerned about the direction of the priest inheritance.

But Jun Qianqian once judged that the murals and stories recorded in the underground palace were more ancient relics than the tokens left by the sacrificial platform.

At the beginning, the symbols on the murals here provided the data she needed to decipher the meaning of the words, and the stories of the beasts recorded on the murals also looked like distant myths.

Originally, Jun Qianqian didn't think that the underground palace would have something to do with the language of the sacrificial platform for a hundred years.

It wasn't until she saw the new cave that the tribesmen accidentally found when they were cleaning up the mud.

"What is this drawing?"

Luo Ze stood beside her, helped her carry the torch, and had just cleaned up the mud, and there were many mud tunnels on the mural, making the marks on the mural blurry and difficult to identify.

"Painting the flood, twice."

Jun Qianqian squinted her eyes, as if she could see the patterns on the mural more clearly.

In this mural, there is no appearance of words at all, only very abstract people and very abstract waves.

And Jun Qianqian finally found the missing piece of the puzzle.

"Was it indigo......

Looking at the people on the mural and the leaves held high in her hands, Jun Qianqian worked hard to identify them for a long time before she finally determined them.

"What's wrong with Indigo?"

Roze remembered what she had said about indigo and fireflies.

"I've actually thought about this, the fabric of the color coat may have been specially treated, and a special potion is needed to reveal the buried secret."

After all, this method was not uncommon in ancient times when it was used to transmit secret letters, and it was also mentioned in chemistry class that there was a kind of charlatan, that is, spraying water on the paper, which could immediately show red handwriting.

In fact, it is just a simple acid-base indicator reaction.

But who would have thought that the indigo would actually serve as an indicator?

"What the hell are you talking about?"

Xia Lan listened to the words of these two people, as if she had something to do with her, and as if she was thinking too much.

"Indigo has a strong color ability and can cover other light colors, probably because of this, I don't dare to risk putting the colorful clothes in the dye vat to soak in it."

Jun Qianqian explained to Xia Lan.

"What? Do you want to dye the silk of your clothes with indigo? ”

Isn't it all a blue piece of cloth?

"But that's how it's painted on the mural, you see, this man is holding a set of pink cloth and putting it inside the indigo."

Caiyi and indigo are both things related to the inheritance of the sacrificial table, and Jun Qianqian thinks that this guess is absolutely correct.

"Just try it."

Roze is also a man of action.

"But if you guess wrong, won't the secret on the colorful clothes be destroyed and you can't decipher it anymore?"

Xia Lan didn't know why the two of them could make such a bold decision.

"Whatever, it's a stalemate now anyway, let's talk about guessing wrong."

Over the years, Jun Qianqian has been taking the colorful clothes with her, and they asked around among the tribesmen, and there were really people with indigo dye, so that they didn't have to go back, so they cooked a pot of indigo in the temporary stronghold of the underground palace, and then put the colorful clothes in.

Xia Lan felt her heart break again.

What kind of inheritance is it, so that the good colored clothes are dismantled into rags and thrown into fuel to cook......

"Has anything changed?"

At this time, Jun Qianqian looked exactly like the old witch in the children's picture book, she held a wooden stick in her hand, standing in front of a large cauldron, stirring it, and the cloudy dye in the pot was still bubbling.

It's like boiling poison and preparing to catch a nest of Smurfs and cook it.

"I can't see it, the taste is too spicy for the eyes!"

The process of making indigo is to ferment, and the taste of fermentation can not be determined, sometimes the batch of indigo has no taste, and sometimes it is sour and smelly, and the smell is very weird.

This time, I used the one that smelled very weird.

"I don't want this colorful coat anymore."

Xia Lan felt that even if Pelo could really weave the sky with her hands skillfully and reassemble these rags into clothes, she would never wear this sour-smelling colored clothes!

"Don't be so disgusted, the blue clothes in the tribe are dyed like this, just wash them twice."

After washing indigo a few times, there will be a fragrance of grass and trees, and the clothes on the altar are dyed with indigo.

"Then I don't want it either!"

Xia Lan's girl's heart was severely damaged.

Finally, when the color clothes are completely soaked in dye, they are fished out, and the excess dye has to be washed off many times.

Jun Qianqian rubbed and rubbed there for a long time, and when everyone thought that they had failed, there were really patterns coming out of the blue!

"I'll just say I must have guessed right this time."

Jun Qianqian pointed to the pattern on the fabric and showed Xia Lan triumphantly.

“……”

It turns out that this colorful clothes really have to be thrown into indigo to dye in order to get the secret of inheritance.

Xia Lan didn't want to speak, and rolled her eyes at Jun Qianqian.

Indigo has a strong coverage, after the colored cloth is put in and dyed, those colors have all become deep and light shades of blue, and the color of those patterns is white.

"What do these patterns mean?"

Jun Qianqian held a circle of paper, and Luo Ze helped her unfold the whole cloth smoothly.

At first, they had guessed that the canvas was a map, but now it seems that the patterns are so dense that they have to be transcribed onto paper to look at them slowly.

"Even if it's a map, what kind of map is this drawing?"

Luo Ze also looked at the patchwork of blue cloth.

"I don't know, we have to determine the direction first, and then find the reference objects we are familiar with, so that we can know that the places indicated on the map are there."

Decryption is like this, often when they think they have guessed the answer to the riddle, they are only pointed to another riddle by clues.

But they've made good progress.

When the tribesmen cleaned up the dungeon, they also kept an eye on it, and maybe they could find other hidden mines and get more clues.

Jun Qianqian and they stayed in the underground palace until the autumn harvest began, and the underground palace did not find any new discoveries.

"This cave that is not painted on the mural should have been dug by the southern tribe hundreds of years ago, so the southern tribesmen at that time also found the underground palace, why haven't they heard of the ancestors of the southern tribe using metal?"

All this is full of suspicions, and when the time for the autumn harvest comes, they will also return to the capital first.

"Let's study it slowly when we get back."

I obviously feel that I am standing at the door of the truth, but this mystery is like a goblin playing hide and seek, but it does not appear.

"Well, it's not bad for a few years anyway."

After going back, Jun Qianqian planned to count the tokens of the sacrificial platform that she had collected again, maybe some clues were missed.
