Two hundred!

Three hundred!

Four hundred!

I've been counting in my heart, and at this moment, we've walked four hundred steps up this straight staircase.

And Qin Yue still had no intention of stopping in front.

At this moment, my hands were already covered with sweat, and cold sweat began to break out not only in my hands, but also on my forehead.

After the first questioning was fruitless, Old Man Qiu chose to remain silent.

And aren't we just like the old man?

No one spoke, just listening to each other's breathing.

After going down the stairs again, Gou Tang deliberately leaned towards me.

"Hey, Zhang Bing, aren't you afraid, don't you usually have a lot of ideas? ”

Listening to Gou Tang's half-joking words, I didn't bother to pay attention to her.

It's all at this time, how can this woman's nerves be so big.

"Isn't it very confusing, your little Yueyue has obviously discovered the strangeness of this staircase, but why do you still have to keep her head down. ”

I ignored the first half of Gou Tang's sentence and focused my attention on the second half of Gou Tang's sentence.

"Let me tell you, Qin Yue is looking for a reference object for this ladder, without a reference object, we may be trapped in this ghost ladder. ”

Ghost ladder?

It's the first time I've heard this term, but it doesn't seem to have been used by the ancients.

"What is the ghost ladder?"

I carried forward the fine tradition that I have always asked if I don't understand, and asked Gou Tang.

"Well, it's hard for me to explain to you, but you can understand it this way, we're walking on a conveyor belt that is moving under our feet as we walk, and this conveyor belt has a reciprocating point that stops when we get to the point where the loop is. ”

Hearing Gou Tang's explanation of the ghost ladder, I felt, why did I get more confused the more I listened?

"Do you see our feet? We're now halfway up this staircase because of the actual distance we're walking down the stairs when the conveyor belt under our feet comes to a standstill. ”

I seem to understand a little, but I don't seem to understand at all.

Although Gou Tang has explained it very clearly, I always feel that this woman is a little lacking in expression.

What she means is that when the ghost ladder stops at our feet, we can move up the ladder, and when the ghost ladder moves under our feet, we will follow the movement of the ghost ladder. If you still don't understand, imagine this ghost ladder under our feet as a treadmill on which you are walking. ”

Under my confused face, I finally heard Qin Yue's voice.

And Qin Yue's explanation is much simpler and easier to understand.

It's like we're standing still at the moment!

It's just that this is too.

More than 2,000 years ago, the Dian Dynasty was able to imitate the principle of a treadmill to build such a staircase?

"Treadmill, what is a treadmill?"

As soon as Qin Yue spoke, he revitalized the already dull and tense atmosphere.

Hearing Old Man Qiu's question, I couldn't explain it to Old Man Qiu, because I had never played with this kind of high-tech fitness equipment.

"A treadmill is a machine that can run in place, at home, as far as you want, as fast as you want. ”

Uncle Cheng obviously played with this kind of high-tech product, and his answer was also very concise and easy to understand.

After Uncle Cheng finished explaining to Old Man Qiu, Qin Yue and Gu Yicheng finally stopped.

Stop and look back at each of us.

"Nine hundred and ninety-eight steps, originally according to my speculation, we could have reached the lower part of this ghost ladder, but now, when we went down to the middle of this ghost ladder, we never took a single step forward on this ghost ladder. ”

Qin Yue's words made the already somewhat relaxed atmosphere solemn again.

"The person who built this ghost ladder must be a person who is familiar with the art of Qimen Dunjia, and this person's attainment in the art of Qimen Dunjia is deeper than mine, or in front of this person, the Qimen technique I learned is just an axe of the class, if we want to crack this ghost ladder, we can only find two references on both sides of this ghost ladder. ”

"However, you should have seen that this thaumaturgist master has eliminated all hidden dangers when he built this ghost ladder. ”

Following Qin Yue's words, each of us turned our heads to look at our sides.

As mentioned earlier, the ghost ladder is flanked by a colorful starry sky.

The stars floating on either side may not be stars, but what they present to us is the starry sky.

The starry sky is vast and deep, and it is impossible for us to leave any traces in these two starry skies.

"If that's so mysterious, let's tie a rope and slide down this half of the waist. ”

Under our silence, Sun Liansheng came up with a novel idea.

Hearing Sun Liansheng's proposal, I think it is quite reliable, not only reliable, but also the most effective.

"This can't be!"

After Sun Liansheng put forward this proposal, Gu Yicheng directly rejected the proposal.

Under the puzzled look of Sun Liansheng and me, Gu Yicheng handed a thousand miles of light in front of me.

"Take a look at the following situation for yourself, if you really can use such a simple method, Miss Qin would have used it a long time ago. ”

Taking the Qianli Tongguang in Gu Yicheng's hand, I looked at the bottom of the ghost ladder with the Qianli Tongguang.

Dozens of miles below the ghost ladder, I saw a black river.

The black river was squirming in the lenses that were shining for thousands of miles, revealing black dorsal ridges and fangs in the wriggling.

It's -

What the hell am I going to do!

How did I forget about the bugs?

Putting down the thousands of miles of light, I handed it to Sun Liansheng beside me.

There is no need to explain this, if we really follow Sun Liansheng's method, then what awaits us is the army of Zerg who show their fangs.

This is not the most pessimistic, what makes me feel the most pessimistic is Qin Yue.

Qin Yue actually used the idiom of the class gate to make an axe to compare the gap between her and this occult master who built the ghost ladder.

"Qi Men Dun Jia a technique in the beginning of a total of 4,320 rounds, after the wind will be the 4,320 rounds improved to 1,000 and 80 rounds, and then to the Zhou Dynasty, Jiang Shang will be this 1,000 and 80 rounds compressed into 72 rounds, after the Han Dynasty Zhang Liang Huangshi Gong taught, Qi Men Dun Jia a technique reformed again, hidden nine games, Yang Dun nine games, a total of eighteen rounds. ”

"The Qimen Dunjia I learned is one thousand and eighty bureaus, and this master of metaphysics who built the ghost ladder should be a master of metaphysics and mathematics who has a deep understanding of four thousand three hundred and twenty bureaus. ”

"I can't crack this ghost ladder in terms of magic, so I can only use the frame of reference in physics to find a way to solve it. ”

Hearing Qin Yue's words, each of us fell into a deep silence again.

I can understand the references, but the difficulty is that we can't set the references under these two starry skies.

The reference is stationary, but the stars in the two starry skies on either side of us move with us.

For example, when a person walks on the earth, he usually feels that the moon or sun in the sky is also walking with him.

The difference in the reference object will determine the difference in the reference object.

And at this moment, the two starry skies we see, are they really very close to us?

I'm not sure about that.

And you can't be tempted.

We're in a dead end, and if we don't get through this puzzle from the Ghost Ladder, we're all going to die here, to put it mildly.

What to do?

At the moment, I was really helpless.

And Qin Yue had already fallen into deep thought.

Gou Tang, Gu Yicheng, and Uncle Cheng are all thinking about a solution to this problem.

I can't just wait here, although I don't know anything about Qimen Dunjia, but I can't sit still here.

Look to the side of the ghost ladder again.

My eyes are still filled with endless and relentless colorful stars.

How exactly are these stars formed?

While looking at the colorful stars, a word suddenly flashed through my mind.
