This question came from the mouth of the long-sleeved boy, who didn't seem to know much about it.

"It's a bit difficult to explain verbally, so I'll draw it for you to see, so that it can be simple and clear." After Su Xiaobai responded to the young man's question, he walked to the incense table.

The others followed.

Su Xiaobai picked up the paper and pen on the table, and he wanted to consume the slip of paper to draw a schematic diagram.

Under his pen, a somewhat deformed quadrilateral was drawn on the paper, with four closed lines, that is, facing the four walls of the temple.

"Well, the team leader's painting seems to be a bit bad."

The short-sleeved boy looked at the crooked box, scratched his head and laughed and teased.

Su Xiaobai also smiled and responded: "It's okay." When I was in elementary school, it was supposed to be the pinnacle of my drawing skills, but now I really can't do it. ”

"As a man, how can you say that you can't? Team leader, you just draw. ”

The short-sleeved boy made a stalk, and Su Xiaobai also admired him, and continued to draw.

First of all, simply draw a cross to mark the upper north, lower south, left west, right east to determine the direction mark.

Suppose there are four people, regardless of identity, with the code names 1, 2, 3 and 4, starting from the top left corner, and standing clockwise on the four corners.

"The next step is the specific game steps, which are actually quite simple."

Su Xiaobai said so, but whenever he went to deduce this process, he would always have a chill down his spine.

In a clockwise direction, Number 1 begins to move along the wall, reaching the position of Number 2, patting him on the shoulder and standing still; Then 2 moves along the wall, does the same action, passes it to 3, and so on, and the four people who complete a circle are considered a four-corner game.

Su Xiaobai used four pieces of paper to draw a schematic diagram of each personnel movement, so that on the last piece of paper, the key to this trick could be shown.

"After No. 1 leaves, the upper left corner is empty, and if No. 4 passes, no one will be able to pat him on the shoulder." The long-sleeved boy looked at the last picture and realized something.

"That's right, so in the case of four people, because there is no one in the upper left corner, the game will stop after only one play."

Su Xiaobai responded, and added another 5 point to the upper left vertex.

In this way, No. 4 taps No. 5 on the shoulder, thus continuing the move of the second lap. And so on, the second lap, the third lap........ The Four Corners game will go on forever.

"So, if we can keep playing, it means that the fifth person besides us, to be precise, has appeared."

After Su Xiaobai finished explaining, he gently put the pen back on the table and wiped the cold sweat behind his back.

Talking about this thing in such a gloomy place, he still has some psychological burden.

But it was not in vain Su Xiaobai's hard work, and the other members finally understood the rules of the game, and began to enter into a deep discussion by the faint moonlight.

I am from the motherland: [After finding this trick, what should we do with it?] 】

Dawei Tianlong Monk: [Maybe you can use a child's urine.] It's just that except for the team leader, our children's urine is just a projection, I don't know if it can work.........]

Little Girl: [You can try.] 】

The three of them all expressed their attitudes, but only "Zhao Zilong" was silent, and he should be a little uncomfortable with offline conversations.

"Zilong, what do you think?" Su Xiaobai took the opportunity to ask, holding his hand on his shoulder.

[Projection: Zhaozilong.] It can touch and complete mechanical actions, but it cannot simulate the original properties of the entity. 】

"I'm okay with that, just do it and you're done." Zilong responded in a low voice, full of recklessness.

After about ten minutes of in-group discussion, the four finalized their positions.

Among them, the position of No. 1 is more dangerous, because it is a node that has been tricked, just in case, it is assumed by a calmer "monk".

No. 2 is "motherland", No. 3 is "Zhao Zilong", these two positions are much safer than No. 1, and it is unlikely that there will be any moths.

And Su Xiaobai resolutely chose the last No. 4 position, that is, the lower left corner, responsible for the important task of shooting tricks and driving away tricks.

[Can you get started, team leader?] 】

Little Girl: [Not yet, the Four Corners game must be played in the dark.] So, we need to wait for it to get completely dark before we can start. 】

[It's true that there's only a little moonshine now.] But there's no sure count of when it's dark! 】

Little Girl: [It will come, wait.] 】

The reason why Su Xiaobai responded so affirmatively was because at the beginning, he had observed the sky outside.

The clouds in the sky are large and thick, with poor light transmission, and it is still raining at this time, indicating that it is a typical cumulonimbus cloud.

At one point, it moves in front of the moonlight, blocking out the glimmer of light and plunging the temple into darkness for a considerable period of time.

And during this time period, it is the best time to play the Four Corners game.

After about five minutes of waiting, the moonlight area on the right side began to slowly shrink, and this phenomenon told them that darkness was finally coming.

[Everyone, get ready, wait until the moonlight is completely gone, and the game will begin.] 】

Su Xiaobai reminded him, and he came back to his senses and looked around the temple.

In front of me, first the Buddha statue was hidden in the darkness, and then the grass shop on the ground was also swallowed up by the darkness.

The shadows are like invaders, eating away at the only light of the moon, threatening to turn the entire temple into a dark cage........

Until....... When the last glimmer of light on his toes was replaced by darkness, Su Xiaobai felt like he was in a cold morgue, and shivered.

It was dark, and the "senior monk" in position 1 had already set off, but in the discussion channel, it was not calm.

I am from the motherland: [A little panicked, brothers, let me pray for the big guys of the East and the West first.] 】

God willing, Amen...... Allah above, the peace of Allah is with us...... Fusheng Immeasurable Heavenly Venerable...... Amitabha, good, good, good.......]

Zhao Zilong in Xia Changshan: [There is no me? As a real man full of guts, I don't really recognize your vision. 】

Great Mighty Dragon Monk: [Please pay attention! It's time to get ready on the 2nd. 】

I'm from my homeland: [Roger.] 】

............

Footsteps were echoing through the space, once, twice, until the third.

Everything went well, and No. 3 Zhao Zilong slapped his back, which means that the critical moment of the four-corner game is coming.

[Team leader preparation.] 】

【Roger!】 】

Finally, it was Su Xiaobai's turn.

Looking up, what was waiting for him in that empty and dark hidden corner?

Whether it is an empty wall or a treacherous and playful fifth person, the answer will soon be revealed.......

[Wait for my news.] 】

He uttered such a sentence as he walked along the wall with a clay bowl, very apprehensive in his heart.
