He took the key and came to the stone gate of the building.

Put the key in the keyhole.

Couldn't open it.

Could it be the other key?

Then take the other key first.

There are also a lot of mosquito carcasses.

Like the corridor on the right, Sun Suo used a large magnet to clean the black mosquito on the left in the same way, and then got the key on the left.

Use the key on the left to open the door.

This time the stone gate was opened.

However, only one stone door was opened.

The keyhole of the second stone gate is on the other side.

There is not even a hairline gap between the two stone gates, so it's no wonder that the hair clone can't squeeze in.

The key on the right opens the second stone gate.

In front, there is another passage of ten meters long.

Sun Suo's eyes quickly focused on the floor of the passage.

The passage is about three meters wide, and the floor size of the passage is one square meter.

The floor is divided into three colors: red, green and blue.

Red on the far left, green in the middle, and yellow on the right.

Each floor has a two-digit number written on it.

After entering the first column, the red floor is 25, the green floor is 63, and the yellow floor is 47.

Sun Suo guessed that Yuanyang would definitely not be able to rush over with a gust of wind.

But he is not good at mathematics, he can only try this first, maybe he will rush over?

As a result, the screen went black as soon as he jumped out, and a hair was sacrificed heroically.

It seems that in order to go through this passage to the inside of the building, you must first solve the number puzzle on the floor?

This was too difficult for Sun Suo, who couldn't solve difficult math problems like 1510 and 2520.

So... by means of exclusion?

Every floor is life or death, and a real person doesn't have so many lives to try.

Fortunately, Sun Suo can use a lot of hair clones to pile up.

If you go down three hairs, you will definitely be able to find the safety floor in the first row.

The passage of ten meters long means that he needs to walk through more than ten floors.

No, the floor with colors and numbers only has seven columns.

Seven times three equals how much? One, three, three, two or three... Forget it... It's so difficult, no matter three, seven, twenty-one, if dozens of hairs go down, you should be able to test the correct path, right?

In order to save Yao's father, he could only sacrifice these dozens of hairs.

Try the red floor first.

die.

Then there's the green floor.

die.

blue floor.

Safety.

Sun Suo took a deep breath, it was time to try the second column.

Try blue floors...

die.

After dying, Sun Suo's hair clone could not be resurrected in place, and returned to the door.

Need to go through the first column again.

Fortunately, the first column of safe floors has been tried just now, and the floor is blue.

Then step on the blue floor first.

die.

"Isn't it? It was obvious that the blue floor was 'live' after trying it out just now! Why did it become 'dead' after returning it? How can I play it? Are you bullying me for not being good at math?" Sun Suo couldn't help but get angry.

After sacrificing more than a dozen hairs, Sun Suo still failed to reach the second floor alive.

After each death, the life and death of the floor seem to be reset.

After the reset, Sun Suo had to try again with the life of the hair clone, but after trying the first floor, he would die when he tried the second floor, and the floor would reset after he died.

This channel doesn't talk about martial arts at all!

Fortunately, after the floor is reset, the color and number of the floor will not change.

No way, Sun Suo had to copy all the colors of the floor and the numbers on the floor of the corresponding color, and was going to ask students who were good at mathematics for advice.

Or post it online to see if anyone can crack it.

The colors are:

RGB.

The numbers are:

25, 63, 47;

51, 64, 11;

56, 91, 71;

23, 64, 34;

62, 87, 42;

15, 84, 42;

18, 42; 30;

"It's really sick! It's just a door, does it need to be so complicated? Is this a problem that can be solved by humans? I'm leaving my words here! Whoever can crack this number puzzle, I will broadcast it live. Piss upside down!" After Sun Suo finished copying the numbers, he couldn't help but yell.

Sun Suo sent a copy to all the students he thought had good math scores.

The passage is inaccessible until the puzzle is solved.

Just do something else first.

Try the newly downloaded Hezhong Cinema APP.

Stuffing a hair in it, Sun Suo created a clone in the Hezhong Cinema app.

Unlike the Hezhong Cinema in the real world, where audiences are everywhere and the scene is extremely lively, the Hezhong Cinema in the APP is empty inside and outside.

There is still one person.

Sun Suo's hair clone.

It's almost midnight now. In reality, the last movie in the cinema seems to start at eleven o'clock. There should still be a small number of spectators who stay up late to watch.

Hezhong Cinema has a total of six theaters.

There is no need to buy tickets for the cinema in the APP. Sun Suo walked in and took a look. Just like the Hezhong Cinema in reality, there are also six cinemas.

Like the Yunren Hospital APP, there are no ghosts yet.

In a sense, the Hezhong Cinema may be similar to the Yunren Hospital Cinema.

They are all just formed, and no ghosts have appeared yet.

Sun Suo also noticed something when he searched and checked the relevant information on the Yunren Hospital's trial ground on the Internet.

Some video creators who like to do research claim that in the past two years, the number of proving grounds has increased dramatically~lightnovelpub.net~ They think this is not a good thing.

If it is just an ordinary place where people have died and the yin qi is relatively heavy, ghosts and wandering spirits that occasionally appear, ordinary soul masters and soul disciples can easily deal with them, and will not endanger ordinary people.

But there are more and more testing grounds, and it is very worrying that one day it will suddenly get out of control. The high-level ghosts in the testing ground break through the shackles of the testing ground and come outside, which is a disaster for ordinary people.

And now more and more trial grounds have space cracks, connecting strange and different spaces.

The monsters in the different space are much stronger than the monsters in the proving ground.

These monsters will be a greater threat to human society.

If nothing else, the appearance of the proving ground itself is crowding out the living space of ordinary people.

If the proving ground keeps appearing, and it appears at an accelerated rate, occupying more and more buildings, there will be less and less living space left for ordinary people.

Although these are not issues that Sun Suo should be concerned about at this stage, they also remind him.

Or to improve your strength as soon as possible.

In case one day the trial field goes out of control, and a large number of ghosts and monsters rush out of the trial field, human society will enter the doomsday. At that time, only the strong will have a chance to survive.

In any case, he must become stronger as soon as possible.

Sun Suo unknowingly manipulated his clone into Hall 2 of the cinema.

It was the same hall where he went to watch a movie with Yao Xue and Li Shiying at night.

The lights in the hall were on, the screen was dark, and no movie was playing.

Sun Suo walked to the seat where he was watching a movie at night, and let the clone sit down there.

As soon as the clone sat down, all the lights in the hall went out.

Then the screen lit up.

The movie actually started.

Seems like... a horror movie?
