pure sky

"Hey, Enomoto, Aoto, are you all right?" Sawano and Serizawa rushed over when they heard the commotion.

Enomoto shouted to Sawano who was lying at the entrance of the cave: "Sawano, do you have a rope in your backpack? Tie the rope to a nearby tree, and come down!"

"Go down?" Zeye was taken aback for a moment, then suddenly realized, "Where is the treasure below?"

When Beicun heard this, he immediately became excited: "Then what are you waiting for? Go down quickly!"

After several people slid down the rope safely, Enomoto walked into the cave holding a flashlight.

The cave was very wet and slippery. At first, there was only one person tall, but the further you went down, the narrower it became, and everyone had to bend their backs to pass.After passing through the narrowest place, the eyes suddenly opened up. It was a stone hall with a square meter of about ten square meters. The torches around the stone hall had been lit, illuminating the interior of the stone hall as bright as day.And Juchuan City, which everyone has been looking for, is on a wall of the stone hall, groping anxiously for something.

Ju Chuancheng didn't seem panicked when he saw the people who came, and it could even be said that he didn't react at all, but just concentrated on groping for something on the stone wall.

"Juchuan City, let's see where you are going!" Serizawa shouted.At last he was found, otherwise, if a criminal escaped from the hands of a dignified barrister, it would be a shame to spread the news.

"Juchuancheng, what are you looking for?" Junko couldn't help asking curiously when he saw the appearance of Juchuancheng.

"Treasure, the treasure should be behind this stone gate, there must be a switch, and the switch must be found." Ju Chuancheng murmured.

Enomoto began to look at the stone hall. It was a small stone hall. The surrounding walls were made of stones, and there were some very regular patterns on the walls.In the entire stone hall, except for the place where they came in, there is only a stone gate where Juchuan City stands. It seems that if there is a treasure, it should be behind this stone gate.

Looking at this stone gate again, there is a turtle carved on the stone gate, with its head and tail raised high and vivid.The tortoise's shell is regularly divided into three by three nine grids, and each grid has nine holes in a three by three arrangement. Except for the nine holes in the bottom middle grid, which are all blocked by things, the other eight All the holes in the grid are empty.

"Kikukawa Castle, have you ever moved the turtle on the door?" Enomoto asked Kikukawa Castle Road who was groping on the wall.

Ju Chuancheng didn't raise his head, but simply replied: "No." His hands were still groping, trying to find the switch of the stone gate somewhere on the wall.

Junko looked at the turtle on the stone gate carefully, and asked, "Enomoto-san thinks that the turtle on the gate is the switch to open the stone gate?"

Ju Chuancheng, who had been concentrating on finding the switch on the wall, couldn't help but his eyes lit up when he heard this, and his groping movements gradually stopped, and he began to pay attention to the movement here.

Enomoto nodded: "But, how to open it?"

As Enomoto said, he walked up to the stone gate, and in the middle of the bottom grid where the nine holes were all blocked, he stretched out his hand and shook the thing blocking the hole, and tried to pull it out again, but it came out easily , What was pulled out was a stone rod about ten centimeters.Enomoto carefully observed the stone stick. It can be seen that the stone stick has been polished by hand and is very smooth, but other than that, there is nothing unique about it.

"If this grid was originally filled with stone sticks, it must be a clue to open the door left by the treasure hunter, but what does the hole full of stone sticks mean?" Enomoto inserted the stone stick back into the hole. , said thoughtfully.

Zeye also walked up to the stone gate, looked carefully at the nine grids on the door, and said, "Since there is a stone rod inserted in one grid, and the holes in the other grids are all empty, then I think the way to crack it should be Just put stone sticks in the holes in other grids!"

Enomoto nodded: "I have the same idea, but how to insert the other grids? Are they all filled like this grid, or are the stone rods inserted in each grid different? If not, which grid should be inserted? A few stone sticks, how do you know this?"

Sawano nodded: "Yes, if each grid can have ten choices from 0 to 9, excluding the grid that has been determined, there are 108 types of permutations and combinations, that is, one billion."

"What? One billion? My God!" Bei Cun couldn't help crying out when he heard it.

Enomoto thought for a while and said, "If stone rods must be placed in each grid, and the number of stone rods in each grid cannot be repeated, there are 40320 ways to arrange them."

After hearing this, Serizawa hurriedly said: "Enomoto, Sawano, let's not talk about how to insert stone sticks. Look at the scene, besides the nine stone sticks that have already been inserted, how can there be other stone sticks? Even if you know how to insert stone sticks , and nothing!"

Enomoto looked around the entire stone hall, then stopped his gaze, pointed to a direction and said to Serizawa: "If you talk about the stone stick, it should be there."

Serizawa looked in the direction Enomoto was pointing at, but saw nothing but patterns on the wall.

"Where is it?" Serizawa didn't understand.

Enomoto found a dagger in Sawano's backpack, walked to the pattern on the wall, reached out and touched the wall, then raised the dagger, and chiseled at the wall, as if trying to dig out something.In just a few seconds, Enomoto dug out a stone stick that was exactly the same as the one that Enomoto had pulled out from the tortoise shell before.

Seeing this, Serizawa hurried to the pattern on the wall, touched the pattern with his hand, and said, "It turns out that this pattern is made of stone sticks."

Enomoto handed the dagger to Serizawa, signaling him to hand over the work of gouging out the stone stick.Although Serizawa was a little reluctant, he still worked hard and temporarily transformed into a small mason.

"The tricky thing now is the solution." Enomoto nodded slightly, narrowed his eyes, put his right hand next to his ear, and kept rubbing his thumb and index finger.

Junko walked to the stone gate and couldn't help but raised her hand to touch the stone turtle's head, marveling at the exquisite carving: "This stone turtle and the stone gate are a whole, it seems that it was polished and carved from a whole big stone. The craftsman who made this is really good, even the eyes of the turtle look like they can move, it must take a long time to carve it like this! But why do you want to carve a turtle on the door?"

turtle……

Nine grids...

For a moment, as if touching the lock cylinder, Enomoto turned his right hand. At that moment, it seemed that the sound of the lock opening echoed in the stone hall.

"I see!"

Seeing Enomoto's iconic action, Junko couldn't help smiling: "Enomoto-san, do you know how to open the stone gate?"

Enomoto did not answer, but looked at Sawano and asked, "Sawano, do you still remember an old Chinese story about a turtle that you heard before?"

Ze Ye was stunned for a moment, and suddenly realized: "Nine Palaces!"

Enomoto nodded: "Yes, the most magical magic circle in the world."

The author has something to say: the title of the next chapter is yet to be determined, and the update date is tentatively scheduled for next Monday

Sorry for postponing the update until today because the internet was disconnected yesterday.

Every time I am full of ambition and hope that it will be finished next week, but now Xiaoheng is less and less confident about his writing speed

After watching the SP, many people said that the locksmith is even darker, but I think the screenwriter is trying to rely on the original.But in the original book, Enomoto has a strong affection for Junko, but in SP. . .Fujidai, you give me back my little pink! ! !
