If Ning Qiushui's identification was not wrong, then the old man in room 209 should be the female doctor in apartment 404 more than 20 years ago.

She was hypnotically brainwashed by her own male patient and controlled.

And the male patient is likely to be the real culprit who caused the tragedy in Yutian Apartment.

However, there is a fatal flaw in this idea and speculation, and that is...... The old lady in room 209 is not dead, she survived the massacre more than 20 years ago.

She was the one closest to the murderer, but the murderer just let her go.

It's weird.

Totally unreasonable.

"Now the two people who originally lived in Room 404 are the most suspicious."

"We can focus our attention on them."

Ning Qiushui said.

Both the man and the woman who lived in room 404 were suspected of being murderers.

The man appears to be a mentally ill person disguised as a doctor, while the woman is the only one who survived the massacre.

Both of these men have great peculiarities.

Rummaging through the room again, this time Ning Qiushui made sure that he hadn't found anything before leaving here.

As he left, he took a special look at the old lock on the door.

"Let's go back to the room first, I have a very special guess, but I need to verify it."

Hearing Ning Qiushui say this mysteriously, Bai Xiaoxiao was also very curious, so she immediately returned to room 707 with Ning Qiushui.

After entering the room, Ning Qiushui immediately took out the old lock he had picked up from room 210 before.

A certain conjecture was born after he saw a new "old lock" appear on the door of room 210.

However, at that time, Ning Qiushui's focus was not on this.

Now that the photo of 210, they have gotten it, is an important piece of information left by Wang Fang.

After coming back, Ning Qiushui was ready to test his previous conjecture.

He pointed the key to room 707 at the lock he had broken when he first entered room 210.

I've tried it several times, but I can't plug it in at all.

"Sure enough......"

A smile tugged at the corner of his mouth.

"What did you find, Qiushui?"

Bai Xiaoxiao stepped forward, until this time, she still didn't know what Ning Qiushui was going to do.

Ning Qiushui explained to Bai Xiaoxiao:

"I was in room 210 before, and I obviously broke a lock, but when we went there just now, we found a new old lock on the door, do you know where the 'new old lock' came from?"

Looking at Bai Xiaoxiao's somewhat confused eyes, Ning Qiushui continued:

"It's Wang Fang's lock on room 210."

Bai Xiaoxiao was stunned.

"Wang Fang? Why did she lock this room, and it was an old lock that rusted like this? ”

Ning Qiushui stared at the door lock in his hand, which was almost completely corroded by rust, and said slowly:

"It's not the old lock, it's the new lock on Wang Fang."

"She probably wants to keep anyone else out of this room."

When Bai Xiaoxiao heard this, she immediately reacted, what did Ning Qiushui want to say, and a strong shock appeared in her bright eyes.

"Wang Fang was in the Yutian apartment more than 20 years ago...... Got a new lock on this door?! ”

Ning Qiushui nodded.

"Yes!"

"There should be two planes behind this door, one is the 'past' of the Yutian apartment more than 20 years ago, that is, the time when the murder occurred."

"The other is the 'future' of the plane in which we live now."

"Wang Fang should have guessed that we would go back to room 210 again to find the clues she left behind, so she deliberately changed a lock for room 210, a lock that we can open through the 707 key in the future!"

"Through these two locks, Wang Fang is sending us a very important message - that is, in these two time and space, the 'past' can affect the 'future'!"

"Because Wang Fang changed the lock of this door in the 'past', so in the 'future' more than 20 years later, another 'old lock' appeared on this door!"

"And the handful of hair that mysteriously disappeared in our room is also the murderer who returned to a certain time and space more than 20 years ago and took it in advance!"

"That's why the hair disappears from under our noses."

"Because once the 'past' changes, the 'future' will also change!"

Ning Qiushui's words gave Bai Xiaoxiao a lot of room to think.

"The murderer can travel between two planes at will?"

As soon as she thought of this, Bai Xiaoxiao felt her scalp tingle.

"I can't rule out this possibility, Wang Fang disappeared after walking into room 404, and the red-eyed man who blocked me at the door of 210 also disappeared in room 404...... If you look at it this way, it is likely that the room is a passage connecting the two planes. ”

Ning Qiushui has begun to string all the details together little by little, restoring the story world behind this bloody door.

Bai Xiaoxiao carefully thought about everything Ning Qiushui said, and if she looked at it from the perspective of another bystander, it would be easier to find loopholes.

"But Qiushui, according to you, the 'past' can affect the 'future', which can also be logical, but the 'future' can't affect the 'past', right?"

"Time is an irreversible process, and I have experienced some copies of similar space-time transformation behind the Blood Gate before, but I have not been able to escape this law......"

"Before you went back to the past and re-observed the incident of Jiang Ah Si, Jiang Ah Si seemed to treat you as air, this is a normal reaction, but Wang Fang is different......

"Wang Fang, who was originally in the 'past', was able to clearly perceive and remember you from the 'future', and even took the initiative to come to the 'future' to ask you for help, does this mean that the 'future' has affected the 'past'?"

Listening to Bai Xiaoxiao's words, Ning Qiushui fell into a long silence.

The future should not affect the past.

But behind this bloody door, the future has affected the past.

This proves that there are still holes in the details of their conjecture.

After thinking for a long time, Ning Qiushui suddenly said a sentence:

"If these two planes ...... Isn't it real? ”

Bai Xiaoxiao was stunned.

Just then, there was a sharp knock on their door.

Knock knock!

Knock knock!

The sudden knock on the door made the two of them tense.

Although there is a high probability that there will be no more danger today, Ning Qiushui still took out the red scissors and held them in his hand very vigilantly.

After opening the door, it was Wen Fei's panicked face.

"Save Han Chong!"

She said in a trembling voice.

pS: Start with two tickets.
