Lin Huai slept until three o'clock in the morning.

When he opened his eyes, he heard a cry.

"Ohh Ohh ohh……"

The cry came from Lu Jin. He cried so hard that snot flowed into his mouth. Lin Huai could only open one eyelid and said, "I'm not dead yet."

"Uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu!" Lu Jin cried even louder, and he threw himself at Lin Huai, "Brother, I am a waste! I caused you..."

Lin Huai said coldly: "Shut up."

Huang Niu had already disappeared while the two of them were still asleep. Lin Huai didn't even pay him a glance.

He knew that sooner or later the scalper would return to the square at seven o'clock in the evening and enter the house he had chosen after the witch's ritual.

However, for some reason, there was a scent of flowers filling the Red Building today. It was stuffy, fishy and sweet, making people feel panicked. Lin Huai walked for a while and found that the scent came from an ordinary man's room.

He sat in the hall, and for a moment his curiosity was as strong as a hundred claws scratching his heart. In the end, he couldn't resist his desire to go and observe, and quietly opened the door.

One minute later.

"Area D——!!"

The deafening sound of vomiting came from the bathroom again. After Lin Huai finished vomiting, he left the hall with vain steps, muttering: "...Curiosity killed the cat."

After successfully warning Lu Jin not to give up and do bad things, Lin Huai, a cat killed by curiosity, climbed up to the third floor. Looking at the big yellow clock at the top of the third floor, he thought for a moment and took out his

"Opening Lightning Strike".

"Opening Lightning Strike" were two beautiful carved pistols, which were cold and cold in his hands. He grabbed the pistols, concentrated his thoughts, and fired a shot at the pillar on the third floor!

A burgundy ribbon sprayed out from the muzzle of the gun, and when it touched the long pillar, it wrapped around it.

"boom!"

"boom!"

"boom!"

The crimson ribbon was wrapped around the pillars, like a net. And before the ribbon fell, Lin Huai stepped lightly and walked up the pillar along it!

With the title of "super strong physical skills", he was like an agile wild cat, quickly reaching the top of the red building - that is, next to the bronze bell - by repeatedly jumping horizontally.

There was no climbing point next to the bell, so he shot again and finally squatted on the beam hanging the yellow bell!

List of small hills!

The entire daughter country was exposed to his field of vision. Through the tall white wall, he could finally see the vague scenery outside the wall.

Facing him was a high hillside. He knew clearly that what he was facing now should be the direction that his group faced when they entered the Daughter Kingdom.

However……

"Tree?" He frowned, "Why is there a tree there?"

There was a towering tree growing on the hillside. However, he clearly remembered that he did not see this tree before entering the "Daughter's Kingdom"!

A strange chill filled his heart. He rubbed his eyes, but the tree was still there.

After thinking for a moment, he squatted on the beam and looked to the right at the risk of falling.

Then, go left.

Finally, he found the hillside they had passed through on the left rear!

"This is impossible." He murmured, "When did our position change?"

When Lin Huai walked out of the red building, he bumped into Lu Jin who was patrolling downstairs.

Seeing Lin Huai coming, he hurriedly ran to Lin Huai: "Lin Huai! There is a problem, something is wrong!"

Then, he stumbled and told Lin Huai what he had seen today.

"...That scalper is not a good person. I originally wanted to tell her to be careful, but when I opened the door, I found that it wasn't her at all!" Lu Jin said horrifiedly, "She was no longer in the room yesterday.

!There is another person living in that house!”

He spoke very fast, but he finally made things clear. Lin Huai ignored him and walked straight to Areas C and D.

After confirming the wind chime code of the first house in areas c and d, he then walked to areas a, b, e, and f.

"It's true," he said.

"Sure enough... what sure enough?" Lu Jin was anxious.

However, in his field of vision, Lin Huai squatted down and laughed happily.

"Hahaha, hahaha." He seemed to burst into tears with laughter, "It's interesting, it's really interesting."

He wiped the moist corners of his eyes, then turned to the confused and anxious Lu Jin, and said softly: "I have discovered the last answer to this game."

"The last answer is composed of the symmetry of the Daughter's Kingdom, the code of the wind chimes, and 'selected on the sixth day but moved in on the seventh day'."

In the room, Lin Huai explained the answer to the mystery to Lu Jin.

"Before entering this village, I was thinking, why is this village designed to be centrally symmetrical? Why are all the houses exactly the same? Why are there high white walls around it? Why is it cloudy every day?

No sunny days?" Lin Huai asked these questions one by one, "In the end, I found that the answer is here."

He used a pencil to draw an xyz coordinate system on the ground: "This is essentially a question of reference system."

"Under the condition of complete central symmetry in all directions, as players, we need to choose a reference system to determine our orientation. Only in this way will we not repeatedly collect the same area, but know that today I am in a

District, tomorrow I will be in District B, and the day after tomorrow I will be in District C..." He drew a regular hexagon on the ground and a small arrow in its center. "Usually, we could have passed these several

Way to determine our coordinates."

"First, the surrounding environment. Not every place on the isolated island outside the Daughter's Kingdom has the same scenery, but they are blocked by white walls."

"Second, the position of the sun. The sun rises in the east and sets in the west, but the top of the Daughter's Kingdom is always covered with dark clouds. We can't see the sun, the moon, and the stars, so we can't tell the direction through celestial phenomena."

"Under the superposition of these two conditions, in this absolutely symmetrical daughter country, we chose the only asymmetrical red building as our direction sign." He emphasized the small arrow, "The red building has only one door, and

That door is facing the 'Area' in our cognition, so we think that the direction pointed by the arrow is 'Area A', but..."

"What if this arrow rotates?"

As he spoke, he erased the arrow and redrawn an arrow pointing to Area B: "If the Red Building rotates at night, when we wake up the next morning, the door facing the door will actually be Area B, not Area A."

Area. But in our perception, the area facing the gate is 'Area A'. Therefore, we will mistake 'Area B' for 'Area A' and confuse the numbers of other areas in turn.

"

"Each woman's house has the same furnishings, and her ghost face is similar, and changes every day. Due to their silence, the investigation workload is huge, and the evil spirits will disguise themselves. The evil spirits in the same location in different triangle areas will

The spirits are all disguised as the same character... Therefore, under the influence of inertial thinking, it is difficult for us to discover that the Red Building has rotated without our awareness."

"The number of the wind chime is just a reminder of this confusion." Lin Huai said, "I didn't figure out the meaning of this almost redundant number before. Now it seems that it is a reminder to us not to worry about coordinates.

The system rotated and ended up in the wrong house."

"As for the reason why you choose your asylum on the sixth day and don't enter the room until the seventh day, this is also the reason. You are not allowed to change the asylum temporarily, and the day in between is the last difficulty of this game. If you don't notice that the Big Red Building will rotate

The fact is, even if you choose the right house on the sixth day, you will go to the wrong room on the seventh day." He put down his pencil, "This is the final secret of this copy. And the house you should enter today is not Area C.

The first one in the second row is the first one in the second row in Area E."

So far, all the mysteries have been revealed.

A huge sense of accomplishment surged into Lin Huai's heart like a tide. He squinted his eyes, revealing a lazy and contented expression that was almost like basking in the sun.

"...And I was able to find that the people in the house had changed because of the unplanned communication between me and her, which enhanced my understanding of her..." Lu Jin murmured, "

Otherwise, according to the average player's level of interaction with Baiyi, it is not enough to discover this loophole..."

As he spoke, he took out the handkerchief from his pocket: "If it weren't for this handkerchief... I wouldn't have discovered that she is no longer the same person as yesterday!"

"Yes." Lin Huai stood up from the floor and stretched, "The answer to the mystery has been revealed. Next, it's my turn to prepare."

"What preparation?"

"You don't think that I don't need any preparation to fight against 115 evil spirits alone?" Lin Huai glanced at Lu Jin from the corner of his eyes and waved his hand, "At seven o'clock, go to the room where you should go.

, and I..."

"Lin Huai."

It was rare for him to hear a voice like Lu Jin's, cautious and serious: "You are not a human being, are you?"

Lin Huai was stunned for a moment and smiled with relief.

"yes."

He gave this answer gently and deftly, and was not surprised how Lu Jin discovered it. Sometimes single-celled organisms, despite their lack of IQ, have European emperor-like intuition that is better than others.

Then, he heard Lu Jin's question.

"What bloodline did you exchange for?" He asked cautiously, "Can you tell me?"

Lin Huai:……

At seven o'clock in the evening, Lu Jin and the scalper who had been hiding for a day stood in the square again.

"Dong-dong-dong-"
