The two of them walked in the direction of the cave by the gloomy moonlight.

It didn't take long for a hole about a foot high hidden behind the mountain forest to appear in front of me.

I saw that the dark black heavy walls on both sides depicted two large, ferocious beast figures, and in the middle of the wall arch, stood a wide stone gate as tall as a hill.

Each corner of the stone gate is inlaid with neat round iron nails, which looks like a cold and solemn atmosphere.

Wei Ziqi noticed something unusual, and at this time, he had no intention of investigating whether what Mo Yu said just now was true or false, and his attention completely shifted to the stone gate.

He had been secretly investigating Lu Qian for a while, but the place where Guanyin soil was produced was too hidden, and there had been no substantial progress.

This stone door looks at least more than 1,000 catties heavy, and the two stone doors are not spliced but integrated, looking tightly seamed.

But Mo Yu knew that there was a living person hidden behind the door, and it was obvious that there was some kind of secret way to open it.

The two of them looked at each other and began to look around very tacitly.

Soon, they found that although the door of the stone door was a two-sided monolithic rectangular shape, the stone surface was unusually smooth and smooth, and a square neat outline was chiseled out on one side, which was divided into nine small squares horizontally and vertically, and what was even more bizarre was that on the stone surface of each small square, a small square carved with strange patterns was stacked.

Wei Ziqi couldn't understand the pattern on it, one hand held his chin and pondered, he didn't understand what it meant for a long time, and couldn't help but turn his head and ask, "Ji Niang, do you know what this means?" ”

Mo Yu recognized at a glance that the square was engraved with Arabic numerals, and this nine-grid is the nine-square grid, combined with this era, it should be related to the "Vena Rubik's Cube", and the gameplay should be to rearrange the small wooden blocks in the order of 12345678, and the one who spells out the result with the least number of moves wins.

At the moment, there is no need to compete with others, so it should be fully rehearsed within the required number of times.

This kind of little game Moyu was played very well when I was a primary school student, and it was simply a question to be scored.

[Tips: Host, you may wish to try to inform Wei Ziqi of the gameplay, so as to improve the other party's favorability of you. 】

For the sake of the advanced skill experience card, Mo Yu decided to adopt the system's recommendations.

Mei Mei raised her eyes and replied to him with a confident smile: "In my opinion, this is probably a little game I used to play when I was a child......"

Then, she roughly explained the rules of the game for rearranging the nine houses, focusing on Arabic numerals.

Wei Ziqi's blue eyes shone like stars, and he was surprised by things he had never heard before.

Without asking her how she knew it was a number, it was just a strange pattern to him, and with a half-believing attitude, he quickly jotted down numbers from 1 to 8, and then began to think about how to rearrange them with the fewest steps.

He hesitated to move the first plank, finishing the top row of numbers in order.

The stone gate moved slightly, and the dust deposited above it fell in an instant.

Wei Ziqi was slightly stunned, brushed the lime on his robe, and turned to Mo Yu with a slightly surprised expression: "It seems that it is just as Ji Niang said!" ”

Mo Yu slowly moved closer to Wei Ziqi without moving, and seemed to unintentionally brush his arm: "No, no, no, it's you who are amazing, I'm just guessing, and I don't play this game well, I lose every time." ”

As she guessed, as soon as these words came out, Wei Ziqi's vanity was greatly satisfied, and his favorability immediately increased.

[Congratulations to the host, the target character Wei Ziqi's favorability towards the host has increased by 10 points, the current favorability is 20, and the advanced skill experience card x2 has been obtained]

This man is unexpectedly innocent at this time, and he believes it.
