treasure hunter

Sensing the approach of the black fish through the whole mind domain, Pei Miao was taken aback, stepped up immediately, climbed onto the shore, then stood on the shore and pulled the rope vigorously, pulling Afa ashore, Yao Wenhu was still in the water, Pei Miao pulled hard again Although Yao Wenhu and Ah Fa didn't know there were black fish in the water, they also helped out together.

Heiyu was already five meters away from them, Pei Miao pulled all of his strength, and with a "crash", Yao Wenhu was pulled up.

As soon as Yao Wenhu landed, Pei Miao slammed Yao Wenhu and Ah Fa to the ground, sticking tightly to the ground. Then, he saw a huge black shadow passing half a meter above them, and then fell heavily on the ground. land.

Ah Fa and Yao Wenhu exclaimed in unison: "What!"

Shining the flashlight, I saw the big black fish wrestling and thrashing on the shore. Seeing such a big big black fish, both Ah Fa and Yao Wenhu were stunned.

Pei Miao rushed over and raised his foot, kicking Heiyu's body. He didn't want to kick Heiyu to death, but to move him away from the shore.

Although the black fish is heavy, but its body is slippery, Pei Miao has great strength, and quickly kicked the black fish away from the water's edge.

Heiyu was still struggling, but Pei Miao came prepared this time. He quickly untied his backpack, took out a few cans of kerosene and a lighter from inside, then unscrewed the lid of the can, and poured kerosene on Heiyu.

Although the big black fish was blind, it could hear Pei Miao's footsteps. When Pei Miao approached it, it tried to attack him several times, but Pei Miao avoided them all. If it was in the water, Pei Miao would be afraid of it. , but on the shore, Pei Miao was not afraid of it.

Ah Fa and Yao Wenhu exclaimed again and again: "My God, such a big black fish, how many sauerkraut fish can be made..."

Pei Miao poured 5 cans of kerosene on Heiyu's body, each with 800ml. He felt that it was enough. After confirming that his body was not stained with kerosene, he slightly stained a piece of cloth he had prepared before, and used a lighter to Light it up, and then throw it at the black fish.

As soon as the burning cloth touched the black fish, the black fish was immediately enveloped in flames, and the fire was raging, taller than a human being. Don't underestimate these cans of kerosene, it is full of power when it burns.

Although the scales of the big black fish are as strong as armor, they are invulnerable to swords and guns, but they have no defensive effect against flames. To put it bluntly, the physical defense is perfect, but... the magic resistance is too low.

The big black fish struggled painfully from the fire, and when it flapped its tail, it leaped up to the height of a person on the ground, but this could not extinguish the fire, it would only increase the contact area with the air, making it burn more violently.

The black fish struggled for about 3 minutes, finally stopped moving, lying on the ground, the flame was burning quietly, and there was a sound of grease. After 6 minutes, the flame gradually decreased and went out.

The black fish had been burned like a piece of black charcoal, with white smoke emitting from its body.

Ah Fa sniffed his nose vigorously, and said, "There is still the smell of meat."

Yao Wenhu couldn't help sniffing his nose, and said with a smile, "Really, what a pity, if this was outside, I would definitely make it into 108 sauerkraut fish dishes."

Pei Miao inspected the big black fish with all his attention, and found that it was really burnt to death, and some of its internal organs had reached five mature levels. In such a situation, even if it became a spirit, it would definitely die.

Pei Miao turned around and waved to Ah Fa and Yao Wenhu, saying, "Let's go, the business is important."

The three continued to move forward.

Not long after Pei Miao and the others left, seven people emerged from the water. These seven people were not wearing diving equipment, and the leader was the guy with a bunch of white hair on his sideburns in the RV.

After they went ashore, a guy spat and said, "I didn't expect it to be so complicated down here. If I hadn't practiced the Black Sky Book, I would probably have drowned."

A group of white hairs took a picture with a flashlight, saw the body of the big black fish, and walked over, saw the big black fish covered in charcoal, still emitting white smoke, and couldn't help but exclaimed: "So there is such a big snakehead down here!" It's a big black fish, thanks to Pei Miao taking care of it, otherwise when we dived over, we would be attacked by this thing in the water, it must be very bad luck."

Several other people also had lingering fears. Although they had practiced Hei Tianshu and thought they were very capable, they didn't think they could beat such a big black fish in the water.

At this time, a person came from behind, holding a mobile phone in a transparent waterproof bag, he said to Baimao: "Brother, we have to follow quickly, according to the positioning tracker, they are about to reach the Stone Forest Oh, last time Pei Miao told the Yao family brothers that Stone Forest is a very powerful illusion formation, people who can't crack it will not be able to get out after entering, we have to keep up."

Bai Mao said: "Okay, speed up and follow, but be careful, you must control the distance, and don't make any noise!"

"Yes." Everyone responded in a low voice, and then stepped forward at the same time, chasing Pei Miao in front of him.

When Pei Miao arrived in front of the Stone Forest, he still didn't untie the ropes around their waists, because he was afraid that Ah Fa and Yao Wenhu would get lost. If they got lost in the Stone Forest, it would be troublesome to find them.

The three of them entered the Stone Forest. Although Pei Miao already knew how to break the formation, he had to observe the position of the boulder while walking, and then calculate it. It was basically impossible for him to follow the previous route with ease.

Because Pei Miao was moving very slowly, Baimao and the others had the opportunity to follow behind him not too far away. The distance was no more than 30 meters. As long as they didn't turn on the flashlight and make no noise, they would be hard to spot.

During the period, Pei Miao also felt a little strange, feeling that there seemed to be someone behind him, but every time he turned his head to look back, he couldn't see anyone at all.

He soon felt that he was oversensitive, after all, only he knew about this ghostly place, how could there be other people.

After passing through the stone forest, they walked for a while, and finally arrived at the gate of the underground palace. Looking at the huge bronze gate, Ah Fa and Yao Wenhu all exclaimed "Wow——".

The three of them walked to the bronze door, looking at the bronze door covered with verdant green, Afa began to look for the words on the floor tiles and the four words at the lowest part of the door - "Heaven and earth are formed".

Seeing these four words, Ah Fa laughed and said, "It's really a secret, haha."

Pei Miao said at this time: "According to what you said, the first problem is a system of linear equations in two variables. Since it is binary, it means that there are two unknowns. The answer is naturally two numbers. I will calculate it according to the problem you said. The answer is 1 rabbit and 49 pheasants, that is to say, the answer is 1 and 49, so the question is, how should the combination lock be entered, 149 or 491?"

Ah Fa raised his eyebrows and said, "It's not that troublesome, just enter an unknown answer, 1 or 49 is fine."

Pei Miao asked puzzledly, "There are two answers, why just enter one?"

At this time, Yao Wenhu asked: "If the password is 1, that would be too nonsense. If others try one by one, it will be easy to open the door."

Ah Fa looked around, and said: "There should be some kind of mechanism, the one that will punish you for entering the wrong password."

Hearing this, Pei Miao couldn't help but look around. The dome here is too high, estimated to be more than 20 meters high. Even if the flashlight can shine it, they can't see what is above it. If there is any destructive mechanism above, they really can't hide Just thinking about it makes my back sweat.

Pei Miao said: "Ah Fa, are you sure, this is not a joke, if you make a mistake, you will die."

Ah Fa thought for a while and said, "Eighty to ninety percent sure."

Pei Miao was still struggling with the previous question: "There are two answers, why just fill in one?"

Ah Fa said: "I said this question is a system of linear equations in two variables. That's because I am a modern person and I don't use ancient arithmetic to calculate. There is no system of linear equations in two variables in ancient my country. In the Qing Dynasty, the mathematician Mei Wen Ding only proposed the theory of equations, which proposed the concept of "polar number", which is mainly used to solve linear equations in two variables. There are basically three kinds of solution methods, dividing the whole into zero, changing zero into whole, dividing zero and adding the whole , called the stacked foot equation, also called the Yingluo equation..."

As soon as Ah Fa talked about mathematics, he was eloquent and eloquent. Pei Miao didn't invite him to give him a lecture on ancient arithmetic, so he quickly stopped him and said, "Say something I can understand."

Ah Fa said: "If you have an answer to one unknown, you will naturally have an answer to another unknown. This is not an exam. You must strictly write the answers to two unknowns."

After thinking about it, Pei Miao felt that what he said made sense, pondered for a moment, and said, "Then you stand back, and I will enter the password."

Ah Fa shook his head: "I won't refund, just enter the password."

Obviously, Ah Fa has confidence in himself. After all, mathematics is the skill he is best at in his life.

Seeing that Ah Fa refused to quit, and Yao Wenhu followed suit, I would not quit either. Even if there was a mechanism, we should bear it together.

Pei Miao said: "Don't make fun of your life, back off."

Ah Fa said: "Let me enter the password." He took a step forward and stepped on a floor tile with a number engraved on it. The number on this floor is 1.

Pei Miao wanted to stop it, but it was too late.

The floor tiles sank about three centimeters, and then, I heard a rattling sound from somewhere, and the bronze door moved, moving to both sides, revealing a gap in the middle.

As soon as the gap appeared, a chill hit their faces, and the three of them shivered in unison. Yao Wenhu asked in surprise, "Why is it so cold?"

The door was only opened ten centimeters, and it stopped moving.

Ah Fa smiled, and said: "Oh...it's designed like this, it seems that both answers are really required to be entered."

As he spoke, he stepped on the floor tile with a 4, and then stepped on a tile with a 9.

The sound of the machine came again, and the bronze door moved again, moving to both sides, and a long and spacious stone step appeared in front of them.

What surprised them was that the dome above the passage inside was full of crystals, and the crystals shone with faint light, adding up to illuminate the passage, but it was very cold inside.

Pei Miao secretly thanked him for being prepared this time. He wore a diving suit over his jacket. This thing is water-repellent and windproof, and has a certain effect of keeping out the cold. Otherwise, they dived and their clothes were soaked before entering such a cold underground palace. , will definitely be sick from the cold.

The three of them walked into the underground palace and walked down the spacious stairs. I don't know how long the stairs are, but Pei Miao felt like they had walked for a long time anyway.

After a while, Yao Wenhu exclaimed in a low voice: "What kind of stairs is this? According to our speed, it is estimated that there are forty or fifty floors down."

At this moment, Ah Fa said: "I have been counting and walked up 725 steps. The height of each step of the stairs here is about 130 centimeters. That is to say, we have gone down [-] meters."

Pei Miao said: "Go on, luckily there are no institutions here, it's a blessing."

So they went on down.

Because the stairs were too long, they stopped to rest twice during the period, and finally, the stairs came to an end, Ah Fa walked down the last step, saying: "There are 2180 steps in total, nearly 400 meters, but the vertical height is less than 400 meters. "

Next, they began to check the terrain here. Here is a huge platform, about 40 meters long and 20 meters wide.

Except for the direction they came from, the other three sides were all empty, surrounded by darkness, they stood on this platform and looked forward, as if they were standing in a dark universe with no boundaries around them, creating a deep feeling for no reason. of terror.

"This underground...is completely empty!" Yao Wenhu exclaimed, "It's so shocking."

Pei Miao saw a stone platform standing in the middle of the platform, and there was a compass on the stone platform. Pei Miao stepped forward to check it with the All-God Domain, and found that the inside of the stone platform was hollow, and there were many mechanisms connected to it. It seems to be able to rotate.

Pei Miao said, "It's a combination lock again, use this compass to enter the combination."

Ah Fa asked: "Where are the hints? No hints?"

Pei Miao walked to the back of the stone platform and said, "Here."

Ah Fa went around to the back of the stone platform, and sure enough, he saw the four characters "Taixuan Dilemma" engraved on the back of the stone platform.

"It's really a secret!" Ah Fa exclaimed happily.

Yao Wenhu asked, "Do you know the answer?"

Ah Fa smiled triumphantly: "If it was someone else, I would definitely not know about it, but by coincidence, I found out the secrets of ten calculations and solved them all."

Pei Miao said, "Then lose the answer quickly."

"Okay." Ah Fa stared at the compass as he spoke, using the compass to input answers was a bit of a novelty, so Ah Fa naturally wanted to study the compass.

Fortunately, this compass is not very complicated, and all the characters are very clear. After studying it for a while, Ah Fa knew how to operate it. First, he turned the outermost circle of the compass, and sure enough, he could turn it.

After turning a few times, Ah Fa stopped and turned to the inner circle instead.

Every time he turned the compass, he could hear a slight compass sound. Seeing this, Pei Miao couldn't help sighing softly: "It turns out that our country had such advanced science and technology in ancient times, what a pity..."

Yao Wenhu looked at him suspiciously: "What a pity?"

Pei Miao said: "It's a pity that it was delayed. At the end of the Qing Dynasty, it was crushed by the West with advanced technology, forcing the Qing government to sign various treaties that forfeit power and humiliate the country."

Yao Wenhu said: "That's something that can't be helped. This is how history develops. I think that because we have been wronged and learned lessons, people in our country know how to work hard."

Pei Miao smiled and nodded: "It's rare for you to be transparent once, it's my obsession."

"Okay!" Ah Fa suddenly whispered, and took a step back.

Suddenly, they felt a slight tremor on the ground, and Yao Wenhu hurriedly asked, "What's the matter, an earthquake?"

Pei Miao felt that the vibration was very stable and not strong, unlike an earthquake, so she said, "Don't panic, maybe this mechanism is a bit big."

Pei Miao was right, this mechanism is indeed a bit big, to be precise, it is very big!

The ground shook for a full 2 ​​minutes, and they finally saw a huge bronze bridge slowly rotating. After another 2 minutes, the bronze bridge connected to the platform they were standing on, perfectly fitting.

"My God..." Ah Fa looked at the bronze bridge in shock. It is ten meters wide, I don't know how long it is, and it is coming in a rotation. Even if it is a project like this, it is huge even now. Know how the ancients did it.

The three of them stepped onto the bronze bridge and walked forward for more than 40 meters. Pei Miao stopped, and he saw the pillars at the bottom of the bridge with all his attention. The pillars at the bottom of the bridge were about 9 meters in diameter, erected in the dark bottomless In the cave, this huge bronze bridge was propped up. Of course, there is also a mechanism inside the religious pillar, otherwise it would be impossible to rotate. Such a project really shocked Pei Miao.

Going forward for another 40 meters, the bronze bridge ends at the end. This bronze bridge is 80 meters long and is supported by a pillar in the middle, which can be rotated. The design is simple, but... because it is too huge, all of this makes people feel Unbelievable.
