"It turns out that there is such a magical experience with this knife, it is so interesting!" After listening to this, Du Chenyu felt very curious, and felt that there was nothing more interesting in the world.

"yes, I also think it's amazing, who let us choose." Wei Zitian forced out a smile and tried to straighten his weak body.

The other side.

"Your story is amazing." Zhang Boyu's eyes were half-open, and his face turned pale: "But what is the principle that makes water freeze quickly?" ”

"Since the great changes on the earth, many new substances have been born." The fire took the ancient book in his hand and placed it on his lap. He helped Zhang Boyu's shoulder and said, "The principle is that the knife released the sulfate Neuer and the positive Neuer. ”

"Neel? What is it? Zhang Boyu was a little puzzled, he had never heard of such a substance.

"Neuel is a newly born substance, and because there are so many types, it is uniformly replaced by Neuel." Fire patiently explained: "Neuel sulfate absorbs moisture from the air and breaks up the atoms of hydrogen and oxygen, causing their number to grow and expand dramatically, so that a large amount of water can be produced in a short time, and then under the action of Neuel, its temperature drops sharply and ice is formed. ”

"Did he feel cold during use?" Zhang Boyu asked.

"I heard him say that Zhengniul only lowers the temperature inside the atom, so it can't affect the outside." The fire opened the ancient book and stopped talking.

"Hmm......" Zhang Boyu closed his eyes and stopped talking. The fire looked at the ancient book, but there was nothing on it except for a pattern. And these patterns, without exception, are all kinds of eyes! And the arrangement of these eyes is very weird, one will be round and one pointed, and the other will be pointed and round, and the direction is different.

"It's strange, why are there all eyes on it? And it's quite weird. The fire fell into deep thought.

Time passed little by little, but the fire had no clue. He frowned, turned the book back to the first page, and stared into that eye.

Suddenly, he had a flash of inspiration, closed the ancient book with both hands, and suddenly said, "Yes, that's what it means!" ”

"What did you find again?" Zhang Boyu slowly opened his eyes and coughed twice.

"I know what this ancient book is all about!" Huo smiled and said, "Do you remember the 'ghost mother' nursery rhyme? The above is definitely related to this! ”

After Zhang Boyu heard it, a glimmer of light flashed in his eyes, as if he thought of something: "Could it be ......?"

"That's right, that's it!" Huo stood up and looked at the ancient book platform: "'He painted Danfeng eyes, and came to the wall' must have another meaning!" With that, he walked back to the center of the altar with the ancient book and put it back in the spread.

"If I'm not mistaken, there must be some kind of pattern here. So let me see what is sacred about this five-page book! Fire took a deep breath and looked in the direction of the tip of his eyes until he reached the opposite wall. He stepped off the stage and walked to the wall. He slowly reached out a hand and touched the wall. It's just that nothing happens. Fire frowned and continued to fumble.

"Click!" As if the fire hand had touched something, he quickly took it away and looked at the place. There is no difference between that place and other places, the only difference is probably the color difference. He pursed his lips, hesitating to press it.

"Ahem!" Zhang Boyu suddenly coughed violently again, and Huo quickly turned around and found that Zhang Boyu's face was like white paper, and his clothes were stained with coughed blood. The fire turned his head and closed his eyes. Then he suddenly opened it again, stretched out his hand and pressed it.

Sure enough, the brick was pressed down, but nothing happened. Fire thinks that things are definitely not as simple as they seem, so he distances himself and waits quietly for something to happen. However, there was no movement for a long time.

"It shouldn't be, it's been pressed, it doesn't make sense!" The fire is a little puzzling, I don't know what the situation is. To make sure, he went back to the ancient book. He scrutinized his first eye, trying to find some clues. However, there is nothing wrong with this eye other than that it looks strange. Fire habitually held his chin and turned the book to the second page. At this point, the eye is pointing in another direction.

"Do you mean...... Do you want to press all the switches? "Fire muttered to himself, feeling that things were not so simple." Forget it, let's try it first, there is no other way out. The fire jumped off the altar and walked in the other direction. After a while, I found another switch. He pressed it again. As he expected, nothing happened.

"Sure enough, it's going to turn all the switches!" A smile tugged at the corner of Fire's mouth, as if the mystery had been revealed. Then he found two more switches. It's just that when he saw the last eye, he was a little troubled.

"God, this eye is actually two pointed ends!" Huo felt a hint of powerlessness for a moment. If Zhang Boyu is not poisoned, it is better to say, the two buttons can naturally be easily pressed at the same time. It's just that Zhang Boyu's situation hardly allows him to walk anymore.

"According to the normal situation, it is indeed necessary to press it at the same time, but, what should be done?" The fire kept looking to both sides and was in a predicament. He didn't think that the two eyes were pressed one by one, because that would make the person who built the place too unintelligent.

"Don't worry, Xuan." A majestic female voice came from the ear of the fire, and the fire immediately looked in the direction of the source of the sound and found the woman in the red gold imperial robe.

"Sister Huang!" The fire covered his mouth, blocking the sound of the upcoming chant.

"I've seen your abilities, so I shouldn't worry about such a predicament." Dayhuang put his hand on Huo's shoulder and said affirmatively.

"However, you're not an entity, and he can't act, and I don't think the builder has a low IQ." Fire shook his head.

"I agree with you, but do you really think you can't press buttons on both sides at the same time?" Dayhuang smiled and removed her hand from the fire's body, then she pointed to the fire's cloak, and then the phoenix bird on her shoulder turned into two flames, each of which flew to the buttons on both sides, forming two rings of fire.

"Have you forgotten? What do you do best? Dayhuang looked at the fire and smiled as he guided.

"What I'm best at......" Huo fell into deep thought, and suddenly had a flash of inspiration, and clapped his hands: "Analysis and hidden weapons!" ”

"That's right," Dayhuang nodded affirmatively, "Since you're best at these two, you should already have the answer, right?" ”

"There is an answer, but ......" Before Huo's words were finished, he was interrupted by Dayhuang: "No but, when you already have an idea, go in this direction, don't hesitate at all!" The fire looked at the rings of fire on either side, then took out a throwing knife from under his cloak and placed it in front of him, silently looking at it. Suddenly, he clenched the flying knife tightly and smiled: "I know, Sister Huang, thank you." ”

"Don't thank me, my phoenix has paved the way for you, have you already figured out a countermeasure?" Dayhuang stepped aside and looked at the fire.

"There it is! You only have one chance, but you can't fail! Fire confidently spun the knife around and looked at the walls on either side. His brain began to calculate. Then he smiled confidently and faced one of the buttons.

Suddenly, he sent a large number of throwing knives out in all directions, like a flying swallow, crashing into the surrounding walls. Without exception, these throwing knives all pierced into the wall. Then he shot a throwing knife in one direction, and hurried to throw another. The two throwing knives cut straight rays in the air, aiming at two of the hidden weapons.

Bang! Bang! After a few crashes, large swaths of hidden weapons fell from the wall, all scattered like heavenly maidens scattering flowers. However, the two throwing knives slammed into the button like cannonballs, sending sparks in the air. Suddenly, the fire instantly took out his pistol, and with a swing of his body, he hit in one direction, changing the direction of one of the throwing knives slightly, and flew straight towards the fire ring. With a bang, two flying knives actually drilled into the ring of fire at the same time and pierced the button!

"Well done!" Dayhuang praised and said, "Look, I'll just say you'll be fine!" ”

"Hmm......" Huo just wanted to say something, but the underground ruins began to shake a little, especially the altar, which shook even more, and Huo had to retreat from the altar to stabilize his footing.

Rumble! The altar with the ancient book was slowly raised, and a statue rose in the center of the altar. The statue as a whole is a huge snake with a feather fan on the upper part, a snake body in the middle, and a majestic snake head on the lower part, which looks directly behind the fire and opens its mouth. On the base of the statue, it is covered with dense vines. Looking through the gaps, it seems that you can vaguely distinguish something. Underneath the pedestal is a pool of clear water, which is not contaminated with mud.

Fire clenched the Tang Knife, beware of the danger that could happen at any time. However, nothing seems to have happened.

"Sister Huang, do you think I should go over and have a look?" The fire turned its head towards the day-phoenix.

"See for yourself, and if you want to see it, then go and see it." Dayhuang responded: "Okay, this time I came out to waste a lot of strength, I'll go back first, and if there's any crisis, call me again." ”

"Okay." As he spoke, he saw that the body of the day phoenix split into countless phoenixes and disappeared into the air. Huo held the Tang knife and walked over slowly. He walked under the statue and picked open a vine with the tip of his knife, only to find that there were words carved into it. It's just that these characters are made up of ancient Mayan characters.

"Fortunately, I learned a lot of words, otherwise I really wouldn't be able to read them." The fire spoke, picking at the large vines on it. Through analysis, the following passage was obtained:

Who fed me wine and made me intoxicated?

The god of darkness said, "It is I."

Who polluted my people after death?

The god of war said, "It's me."

Who overthrew my rule?

Trakhupan said: It's me

Who stole the treasure?

This is the end of the discourse, and there are no other words below. Fire frowned, not knowing what this sentence was trying to mean. He cut down all the vines, and no other words appeared.

"This is an evil door, it shouldn't be, there should be words." Fire touched his chin and began to search around the statue of the snake god. Suddenly, he was attracted to a small, bulging object.

"That's ...... buttons? The fire held on to the pool platform, and when he looked down, he found a raised button.

"Do you want to press it?" Fire looked at the button and hesitated. He rolled his eyes and decided to press it anyway.

Boom –

The Quetzalcoatl statue began to shake, and the fire hurried back to the front of the statue. With a click, a treasure box spat out of the snake's mouth and fell right into the arms of the fire. The fire quickly hugged it and didn't let it fall. After the statue of the snake god stopped shaking, Huo took out the treasure box in his arms and placed it in front of him to look at it.

The box was a wooden chest, and it didn't look like anything peculiar. He held the treasure box and touched the lid with his hand, trying to open it. To his surprise, the treasure box actually opened a crack!

"That's weird, is the builder so brainless? Can you open it by giving a treasure box? Fire raised an eyebrow and began to doubt the builder's intelligence. However, he did not stop and chose to open the box. Inside the box is a sheepskin scroll. He put the box down and unfolded the scroll. It reads the second half of those words:

Who stole the treasure?

Yaki Feathered Serpent said, "It's me."

Who is guiding the way to survival?

Quetzalcoatl said, "It's me."

Who saved the man of destiny?

Manna said, "It's me."

Who took Quetzalcoatl's golden eye?

Wei Lixuan said: It's me
