I thought about it, and it didn't seem to be anything special other than the slight sinking of the stone slab under my feet when I reached a certain area, triggering the launch of the trap......

"Wait a minute, there's something so special!"

A flash of inspiration suddenly flashed in my head, and I said with some excitement. Ｘ

Just now, out of the corner of my eye, I accidentally saw some patterns faintly carved on the stone slab under my feet.

I was so flustered that I didn't pay attention to the meaning of the patterns on the slate.

Now that Uncle Ma reminded me of this, I looked over from afar, and with my extraordinary eyesight, I could see those patterns clearly.

I led the group cautiously to the edge of the "Death Passage", leaning down to carefully observe the stone slabs under my feet.

Sure enough, they all saw certain words carved on the stone slabs.

Because they were all covered by corpses before, and they didn't think about it at all, even the experienced Uncle Ma didn't notice it.

I motioned for everyone to step back, then took out a Heavenly Fire Talisman, activated the True Qi in my body, and cast a spell:

"South away from the heavenly fire, turn into samadhi, refining!"

In an instant, flames surrounded the entire hallway with corpses.

Anyway, it's already a corpse, so I'll be kind enough to help cremate it!

After about ten minutes, the flames gradually extinguished.

Because it was Nanming who left the fire, the strong flames were burned out along with the ashes, and in the end there was nothing left, all turned into air.

When the corridor was cleared, we realized that the stone slabs in front of us were actually carved with different characters.

After Uncle Ma's identification, these words are all numbers marked in regular script.

And the numbers on each slate variety, ranging from one to hundred, and they are disorganized and irregular.

"Could this be the legendary digital mechanism?"

I asked Uncle Ma curiously.

Uncle Ma nodded and said in a deep voice:

"It's really a digital mechanism, just like the ancient combination lock, if you make a mistake, the mechanism will be triggered, and the game will be over. But if you go right, you can save your life and get out of the way. ”

Looking at the dense numbers in front of me, I couldn't help frowning:

"But with so many numbers, what is the password?"

Uncle Ma shrugged his shoulders and said with a sneer:

"Don't ask me, my math was taught by my PE teacher."

Ma Jiaqian said coldly:

"My dad taught me!"

As soon as he heard this, Uncle Ma's smile immediately froze on his face.

Obviously, even he, a father, never thought that Ma Jiaqian would have such a cold and humorous side.

But fortunately, in addition to the three of us scumbags, there is also a genuine scholar Xiao Wei.

She took out the notebook she had with her from her backpack and asked Uncle Ma to translate all the numbers on the slate.

I looked over and saw that all the numbers were divided into twenty rows of four, for a total of eighty numbers.

Then from the first row, the numbers are:

1，3，5，7

2，4，6，8

9，10，12，15

16，18，20，22

23，25，26，29

32，35，36，38

40，44，47，49

……

Until the end, even hundreds of hundreds appeared, I was simply dazzled and dizzy to see.

However, Xiao Wei had a serious face, constantly calculating in her notebook, as if she was a female student.

"There must be some connection between these numbers, definitely!"

Xiao Wei muttered to herself, as if she was full of confidence, but as if she was cheering herself up.

I saw that Xiao Wei couldn't come up with an answer for a while, so I took out the vajra talisman again and decided to help her explore the law first.

I propped up the protective shield and stepped on the stone slab marked 1 on the far left.

The slate only sank slightly, and did not shoot sharp arrows.

I was secretly glad in my heart, and continued to move forward, stepping on the stone slab marked 2 in front of me.

Immediately, sharp arrows shot from the stone walls on both sides, striking the protective cover, causing ripples in circles.

I quickly retracted my steps and cautiously walked towards the stone slab marked 4 next door, and sure enough, the mechanism was not triggered.

So I continued to probe forward and walked to the third layer of the slate marked with the number 10, and unfortunately I was hit again.

Looking at the crevices looming in the protective cover, I swallowed to myself.

If I'm unlucky enough to trigger the trap, I really won't be able to hold this protective shield.

I tentatively stepped on the No. 9 slate next to 10 again, and I was safe!

Finally one step forward.

At this point, I had managed to advance three floors.

But there are still more than a dozen floors to go.

When I think of this, I also feel uneasy.

However, I was afraid to return, so I continued to cautiously test forward.

On the fourth floor, I chose slate 16.

Blind again!

It's like playing Russian roulette, it's all about luck.

The so-called Russian roulette is not the kind in casinos, but a suicidal, desperate game.

Participants place one or more bullets in the nest of the revolver, after which the cartridge disc is rotated and then closed.

Participants take turns holding their pistols to their heads and pressing the trigger until someone is shot, or afraid to press the trigger.

If I hadn't had the protection of the vajra talisman, I would have failed the second round.

For now, I managed to reach the fourth floor cautiously with the help of the plug-in mode, but my good fortune was over.

As I stepped into the fifth layer of stone slabs marked No. 23, bow and arrow launches appeared on both sides of the stone wall again.

Seeing this, I shouted, "I'm dripping", turned around and ran back.

At the same time, the sky was full of arrows that shattered my protective shield in an instant.

And the moment the protective shield shattered, I jumped desperately and rushed out of the death zone by a fraction of a second.

"It's dangerous, it's dangerous! Thanks to my quick reflexes, I would have been shot as a hedgehog. ”

I patted my chest with palpitations and sighed.

It seems that the further you go, the more there are bows and arrows, and even the protective shield is not enough to ensure safety.

However, I tried desperately, and finally helped Xiao Wei get some useful information.

The first four layers of security numbers are 1, 4, 9, and 16.

But what is the particular pattern between these numbers?

"Wait! Isn't that the number from 1 to 20 squared! ”

Xiao Wei suddenly realized.

According to her explanation, the slate in front of her is divided into twenty layers, each layer representing a number, and they are progressing in turn.

The first layer represents 1, and it's still squared at 1.

The second layer represents 2, and it is squared at 4.

The third layer represents 3, and it is squared at 9.

And so on, and the square number of the numbers in each layer is the correct slate.

Listening to Xiao Wei's explanation, the three of us scumbags suddenly realized.

It turns out that this ancient trap still contains mathematical operations, which is really brain-burning.
