Cai Yan screamed, layers of goosebumps all over his body, and he couldn't care about anything, he only rushed in the direction of Shi Xin, and said in a panic: "Master...... Senior brother, there are ghosts, there are ......"

When he rushed back to the edge of the pool, Cai Yan was shocked, looked at Shi Xin, who was motionless, took a breath, and thought: I'm also timid, isn't it just white bones, what is there to be afraid of. I glanced at it in a hurry just now, and it seemed that I saw that the rock was a little different, could it be the secret way to get out? Now that my brother is unconscious, I must cheer up, as long as there is a way out, we will be saved.

Cai Yan cheered himself up and went to that place again. It's just that girls are naturally timid and naturally resist darkness, corpses, seclusion and related things, otherwise Cai Yan wouldn't say "ghost" as soon as she touches the white bones. Finally pacing to that place, Cai Yan found that there were dozens of skeletons lying around, looking at the clothing style on it, Cai Yan deduced that the white bones were not all from the same era, the farthest was about a hundred years dead, and the latest was only twenty or thirty years.

"So many people have been rushed in? Or ...... They also found this place, and looking at the integrity of their bones, it didn't look like they died in a fight, it seemed to be ...... Starving to death?" Thinking of this, Cai Yan became worried, "Yes, although the food in the bag is abundant, there will always be a day when it will be exhausted, and even if the senior brother is better, we will all starve to death." ”

Since Shi Xin's life is no longer in danger for the time being, Cai Yan certainly doesn't think about the issue of "living and dying together", he just wants to find a way out quickly and save Shi Xin.

The rocks around the Night Pearl are apparently polished, very smooth, and the color is different from the one next to it. Cai Yan groped along this part of the different rocks, and sure enough, he found a thin crack. The cracks form a large rectangle, like a stone door.

"It's a door, sure, but how do you get in?" Cai Yan kept groping, and suddenly his fingers sank, as if he had touched some button, and then there was a dull sound from inside the stone door. At the same time, a row of small characters slowly protrudes under the night pearl.

Cai Yan was taken aback and looked at the small characters intently. The small characters are carved in stone, and it is estimated that they were pushed out by the mechanism that Cai Yan just pressed.

There are three rows of small letters, the first row reads: If you answer correctly, you can go in; If you answer incorrectly, you will fall into a trap and die. The second row reads in a strange "symbol": 666?2;=?. In the third row are 888888 of these six strange symbols, oval in shape, which seem to turn up and down, followed by a small square stone block with the word "confirm" engraved on it.

"Trap from the sky?"

Cai Yan swallowed his saliva and looked up at the swarthy roof of the cave above in fear, for fear that something strange would suddenly fall from it.

Cai Yan sat on the ground in a daze, and at this moment he was not afraid of the white bones next to him, and fell into a burst of despair: "What is this question, and who came up with it? I have never seen these symbols, let alone answer them? Isn't this a dead end? Alas...... It would be nice if the senior brother was awake, he has a lot of ideas, and he may be able to answer. ”

As the saying goes, "If you don't forget, there will be an echo", Cai Yan's heart actually worked, and after a while, there was a weak moan next to the waterhole, and Shi Xin really woke up!

"Senior Brother~"

Cai Yan was overjoyed, tears flowed down his eyes, and he flew to Shi Xin with a cry.

Gently patting Cai Yan's back, Shi Xin felt like a world away. He was still weak, but now that he had woken up, Sun Moon Stone's "Recovery.Proficiency" talent worked together, and he wouldn't have died. Although he was seriously injured and fell from a height, his cultivation at the moment was no longer comparable to that time, and his body had become very strong after a year of training in the camp.

Shi Xin comforted Cai Yan softly, and then asked, "Yan'er, where is this? Is there anything to eat? I'm hungry." ”

As soon as Shi Xin woke up, Cai Yan immediately had a backbone, and his movements were much sharper, and he picked out a few soft foods from his bag and waited for Shi Xin to eat.

After the food was down, Shi Xin's spirits were greatly lifted, and he was able to stand up with Cai Yan's support.

"Senior brother, slow down, that mechanism is not far away. Shi Xin's body was heavy, and almost his entire body was supported by Cai Yan. If it were an ordinary girl, she would definitely not have enough strength, but Cai Yan was also a fourth-class pulse master, and this kind of thing would not be difficult for her.

A burst of girl's unique body fragrance drilled into Shi Xin's dog nose, and his heart fluttered, and his hand squeezed Cai Yan's waist hard, his hands were full of condensed fat, and his obscene face showed a satisfied expression. Who thought that this force touched the internal injury, and he screamed out "ouch" in pain.

"What's wrong, does it hurt in your body?" Cai Yan asked distressedly.

"I didn't ...... Thing, it's fine. Shi Xin shouted that he was not human, and at the moment of life and death, he even thought about that beautiful thing and offended the goddess. He hurriedly gathered his mind and leaned forward step by step.

After being reminded by Cai Yan, Shi Xin was not much surprised when he faced the white bones all over the ground, and only cared about the topic on the stone gate.

"666?square?Isn't this questioner also a traverser, otherwise how could it be such a strange number?At this time, Arabic numerals have not yet been transmitted to China, and the expression of squares is even more impossible......" Shi Xin was stunned by the question in front of him, and his head was full of thoughts, all of which were the identities of the questioners, and what was his purpose?

It was Cai Yan who reminded him, "Senior brother, what is this topic? Is it difficult? If you don't know, don't be reckless, let's think about it in the long run, otherwise as soon as the trap falls, we will have to explain here." ”

"It's hard, it's very difficult! I can solve this world. Shi Xin is not bragging, this topic does not belong to this era at all, even Zhuge Liang, who is wise and wise, can only sigh lightly.

Shi Xin sat cross-legged on the ground, reaching out to the dirt and counting. He explained to Cai Yan while calculating: "I once saw in some ancient books, this is an arithmetic algorithm. But it's also quite complicated. ”

Cai Yan didn't ask him about any ancient books, and he probably couldn't tell him clearly when he asked, so he only reminded him vigorously, "Since it's complicated, senior brother, don't speak, just concentrate on calculating." ”

This is a very basic calculation problem, and Shi Xin carefully listed the vertical formulas in a pretentious manner, and exaggerated them with oil and vinegar, so that the problem was solved. After solving it, I checked it twice to make sure that it was safe.

Cai Yan couldn't understand what he wrote at all, only to see a large list of strange symbols, which could be seen without Shi Xin's description.

The final number was 443556, exactly six digits. Shi Xin stretched out his hand to push out the above number on the 888888, nodded at Cai Yan, who looked nervous, took a deep breath, and pressed "OK".

The "OK" button was pressed by him, and it immediately retracted. There was another sound of a machine, and the stone door opened to the left with a "boom" of dust, revealing a deep and mysterious corridor.

Shi Xin grinned, "Alright, let's go inside!"

"Senior brother is mighty!" Cai Yan also smiled, "Bring food before you go in, just in case." ”

"Haha, it's still a senior sister thoughtful. ”

After Shi Xin finished saying this, he suddenly heard a "boom" sound, and the stone door was closed again.

"How can this be?" Cai Yan was shocked, and his steps towards the food suddenly stopped. At the same time, there was a whoop overhead, and a large area of unidentified liquid poured down.

Shi Xin's face changed color and he shouted, "Danger! It's a trap." Let's get in quickly. Pulled Cai Yan and rolled into the corridor.

"Bang!" the stone door closed just after the two entered, and there was a loud noise. There was a corrosive smell of acid in the air, the smell of the liquid that had just fallen.

Cai Yan hurriedly got up, frightened, and muttered, "This ...... This ......"

Shi Xin sighed and took her hand, "Let's go!"

At the end of the corridor is another stone door, this time the two of them can see clearly, there is a circular protrusion on the left side of the stone door, as long as you press it, the question will appear again.

"Who was the smartest, most wise, and most handsome emperor in Chinese history?"

The following options are: Ying Zheng, Liu Che, Wang Mang, Li Shimin, Kangxi.

Shi Xin laughed, "It's another crossing question, how can you answer this?"

Cai Yan has studied history quite a bit, and frowned: "Senior brother, this Yingzheng, Liu Che, and Wang Mang are all emperors in history, but Wang Mang's traitors should be eliminated first." The remaining two people, Li Shimin and Kangxi, Shu Wenji are lonely and unheard, and they can't remember which dynasty they belong to, and even in the legends of ancient times, they have never heard their names. This question is really incredible, and it makes people want to break their heads. ”

"Yes, yes!" Shi Xin replied casually, but he kept pondering in his heart: all topics, especially such ambiguous ones, it is particularly important to guess the intention of the person who wrote the question. The emperors in the options, each of them is a generation of overlords recorded in the history books, except for Wang Mang. Regardless of the black history of his usurpation of power, how can He De be lined up with these people in this short period of more than ten years?

This is a huge loophole, or rather a hint. Shi Xin suddenly woke up to all kinds of speculations about Wang Mang on the Internet in later generations: Wang Mang, the word giant!

As soon as he thought of Wang Mang's words, Shi Xin laughed inexplicably: Jujun? is not only big, but also huge, how huge? His various unbelievable deeds have been clearly picked up on the forums of later generations, and everyone speculates that Wang Mang is a modern person who has traveled to the end of the Western Han Dynasty!

Linked to the question of the first stone gate, Shi Xin no longer doubted that these two questions and various mechanisms were all from the hand of the traverser Wang Mang!

According to Wang Mang's character, he may think that he is the first emperor of the ages, and even if he is not, the answer to this question must be him.

"The smartest, most wise, and most handsome and invincible emperor is obviously joking, but whether it is joking, ridicule, or self-deprecation, it is actually to let the answerer guess Wang Mang's identity as a traverser, and the answer must be him. ”

Shi Xin stretched out his hand and pressed the answer "Wang Mang".
