The blood flowed from the darkness that could not be seen, and in the dim light it looked like an ancient mythical monster that had been given a new lease of life, and although it was slow, it flowed downward in an unstoppable trend, dripping on the marble tiles with a very slight sound.

Xu Zitong's screams were muffled in the palm of her tightly covering her mouth, her eyes widened and closed tightly, and she buried her head hard in Gu Yan's clothes.

Gu Yu looked at the blood with an expressionless face, and took another foot while comforting Xu Zitong.

However, just as her right foot stepped up the stairs, something strange happened—the lights in the hall turned on again, and the blood that had been flowing for a second disappeared in front of her eyes in an instant.

"Huh?" a string of question marks popped up in Gu Yan's mind, "What's the situation?"

Xu Zitong also opened his eyes tremblingly, and when he saw the situation in front of him, he was also stunned in place, "Wasn't there blood there just now, just now, why did it suddenly disappear?"

"Sister Zitong, wait for me..."Gu Yu suddenly thought of something, let go of the hand she was holding herself, and tentatively stepped on the next level.

The lights went out again, and the blood reappeared, but much closer than the last time.

"Gu Fei, what are you going to do?" Xu Zitong stood in place with his arms in his arms, and when he saw that Gu Yu was going up, he was so frightened that he didn't dare to move.

Gu Yu looked intently at the highest step of the stairs, narrowed her eyes slightly, and after a while, she suddenly raised the corners of her mouth, "I'll just say it... The blood didn't exist at all, and the floor tiles of the steps were actually put together by a high-definition display, which was hard to identify because the light was too dim. ”

As she spoke, she took another step up, pointed to the lights that came on again in the hall, and explained: "Each step is a light switch, which is activated by gravity, and controls the distribution of the hall's and the floor tile display screen, so as long as we step on the steps of the control hall every time, we won't see the blood anymore." ”

Xu Zitong also reacted when he heard this, raised his foot and tentatively stepped on the second step, and when he saw that nothing happened, he immediately smiled happily, "Gu Yan, you are too powerful, you can guess this! Fortunately, I told the people in the program team in advance that I hope to be in a group with you, if I let me do it alone, I will be too scared to move!"

Gu Yu stretched out her hand and pulled her up, and couldn't help but laugh when she heard the words, and quipped: "Then if you meet Xinning, it is estimated that you will have seen it in this issue, and the hot search is scheduled, #徐梓桐陆馨宁抱团害怕#." ”

Xu Zitong was amused by her words, "Why are you so stalked, I was super scared just now, I can still laugh at this time, Gu Fei, I will follow you this issue!"

Gu Yu secretly rejoiced in her heart: That's good, it saves me from having to catch people one by one when I want to "kill" them later.

The two went up to the second floor, Gu Yu felt the light along the wall and turned it on, only to find that it was actually quite spacious, with several rooms on both sides of the long corridor, and a blank small door number hung on each door.

Unable to tell where the sound they heard downstairs just now came from, the two decided to search from room to room, but found that all the doors could not be opened, and they couldn't help but feel a little discouraged.

At this moment, the sound of high heels walking again came from above the heads of the two of them, which shocked Gu Yan in an instant.

She turned her head to look at the end of the corridor, looked at Xu Zitong, who was also shocked, and lowered her voice, "There is another layer." ”

Xu Zitong licked his lips, "But the corridor is obviously a dead end." ”

Gu Yu looked around, "So there are definitely mechanisms or secret doors here that we haven't found, let's look for them separately, Sister Zitong, you carefully touch the wall to see if there is anything abnormal, such as the wall is hot or the wallpaper is raised." ”

Xu Zitong also watched the last issue of "Soul Escape" before he came, nodded when he heard the words, and began to look for it seriously without saying a word.

Gu Yu walked to the wall at the end of the corridor, first knocked on it with her fingers, and then pushed it hard, but the wall didn't react at all.

She scratched her chin in annoyance, turned her head to look at the door next to her, and scanned it up and down to try to find a way to enter, but there were no locks on the doors, and the whole thing was just a plank, not even a single gap.

And just when she was at a loss, Xu Zitong finally made a discovery.

"Gu Fei, I found a piece of chalk!" she pulled out a piece of broken white chalk from under the carpet in the corridor, and excitedly held it up for Gu Yu to see.

"Chalk?" Gu Yu stepped forward to take it, frowning thoughtfully, "Why is this kind of thing here?"

Xu Zitong thought for a while and pointed to the door number hanging on the door, "Could it be written on the door number?" My little niece has a similar one on the door, and every time I go to her house, the door number will change with a new pattern. ”

Gu Yan's eyes lit up, "There is this possibility, otherwise it wouldn't have appeared inexplicably... Go give it a try!"

But looking at the eight identical doors in front of them, the two quickly fell silent again.

"Then we... Which one to try first?"

Gu Yu stood in place for a moment, then picked up the chalk and put it in front of her eyes to look at it carefully.

"What are you looking at?" Xu Zitong stepped forward and asked curiously.

"I'm looking to see if there are any traces of use..."Gu Yu pinched it and turned around, her eyes fixed on the broken chalk.

It stands to reason that the fracture of the chalk must be rough and uneven, but there are some smoothed places on this piece of chalk, although small, but it has not escaped her eyes.

Gu Yu curled the corners of her mouth and said firmly: "As long as we find any door plate with traces of chalk residues, we can find a way to go up." ”

After finding the key clues, the rest went much smoother, and it didn't take long for the two to notice that there was chalk ash on the door number on the third door on the left side of the hallway, but then a new question arose - what was the "code" that allowed the door to open?

"Why don't you try 'Open Sesame'?" Xu Zitong suggested.

Gu Yu quickly wrote down these four words, but the door did not respond.

"That's... Just 'open the door'?"

Still no response.

Later, the two tried "open", "OPEN", "open", "start", and other words that might open the mechanism, but the door still did not respond.

"We can't find the wrong clue, right?" Xu Zitong couldn't help but yawn, "What if this is actually a trick to confuse us." ”

Gu Yan touched her chin and looked at this door number seriously, opened her hand to compare the size, and muttered: "The average door number will not be so big, does it mean that you have to write a lot of words......

She tentatively wrote her and Xu Zitong's names, originally without hope, but in the next second, the door suddenly made a "click" sound from the inside, and then slowly moved away under the gaze of two pairs of shocked eyes, revealing the elevator inside.

"I'm going, I actually want to write a name?" Xu Zitong couldn't believe it, "Who can guess this!"

Gu Yu couldn't cry or laugh, and spread her hands helplessly, "It's lucky to be right." ”

The two sighed as they walked into the elevator, Gu Yu pressed the button on the 20th floor, looked at the slowly closing elevator door, and suddenly had an ominous premonition for some reason.

Sure enough, in the next moment, a feeling of weightlessness suddenly hit, and her body fell completely uncontrollably.

Before falling into darkness, Gu Yu sighed silently in her heart.

Sure enough, the routine of the program team can never be guessed.
