The second experiment broke the formation, when Sun Hao woke up three hours later, this time it was obvious that the little black dog and the little black fat man secretly colluded together, whether Sun Hao punched or scissors or paper, the two of them would make the same, and the result can be imagined. Mobile

Sun Hao didn't immediately touch the protruding switch next to the stone door, but stood in place and saw a white lotus with a golden wire edge in his eyes, and kept observing each stone door, as if he wanted to see through the hard stone door, but in the end he didn't find anything at all, so he walked to the stone gate in the northwest direction.

Knock knock knock......

Squeaky ......

He tried to knock on each stone door with his hand a few times, and then put his ear on the stone door to listen, and found that behind each stone door could hear a strange creaking sound, he listened to it more than ten times, and finally found that the sound behind each stone door was regular, and it would ring in about two minutes, the only difference was that the sound behind each stone door lasted for a different time.

"Multiple choice questions can't help me, when I was a child, a master of the exam told us that if you are short, you should choose the long one, and if you are too short, you should choose the less. Sun Haochi adhered to the method of judging the multiple-choice questions on the earth's exam, and came to the west gate where the sound lasted the longest in advance, and when the sound sounded, he immediately slapped the protruding stone without hesitation.

This time it reacted faster than the last time, and within a minute of his filming, the whole space began to shake violently.

The little black fat man didn't know what was wrong, an excited expression immediately appeared on his face, and when the shaking was about to stop, he suddenly shouted, "The Terran boy stood firm, hug the little girl tightly." ”

Although Sun Haochi didn't understand what was going on, he still did as the black fat man said, and hurriedly ran over to protect Ling'er in his arms, and then heard a loud bang!

With a bang, the entire ground of the stone hall suddenly disappeared, and Sun Haochi wanted to use his blood to shake the air to fly, but in the end he found that he couldn't fly at all, so he hugged Ling'er and fell straight down.

The time of this fall was greatly unexpected by Sun Haochi and the others, although they did not calculate the time carefully, but they also knew that at least more than an hour had passed, which was quite a terrifying number.

An hour or so is almost equal to three hours on Earth, and their descent is much faster than that of a parachute jump, reaching a rate of almost 100 meters per second, or a full 6,000 meters in a minute.

In three hours, they descended by 360,000 meters per hour, and in three hours they descended a distance of more than one million meters, which reached almost one-tenth of the diameter of the earth, and Sun Hao would never have dreamed that one day he would go down to the ground of a planet of millions of meters.

Descending a million meters rapidly, even if he was physically strong, he would be fatally injured if he fell directly to the ground, but fortunately, in the first few seconds of seeing the ground, he was finally able to fly, although he was given very little reaction time, but it was enough to get him out of the fate of falling to his death.

Bang bang bang......

With a loud bang, Sun Haochi and the three of them fell heavily on the hot ground like lava, smashing the ground into three holes more than ten meters deep. This is also thanks to the fact that the three of them are quite physically strong, and they reacted in a relatively timely manner, so they were not directly killed, but only suffered some minor injuries.

Sun Haochi jumped out of the pit with Ling'er in his arms, gently put Ling'er on the ground, and then began to look around.

The place he was in was about the size of the stone hall above, but the floor and walls below were burning, emitting a wave of billowing heat, and there were places where it was clearly burning, as if he had come to a lava hell.

In addition to the extremely high temperature and the burning and fiery ground, there was only a stone cave with a diameter of three meters and a height of more than five meters in front of them.

The little black dog jumped out to extinguish the fire burning on his body, looked at the little black fat man who was thinking with his chin in his hands, and said in a weird way, "Dead fat man, you seem to have reminded Sun Xiaozi and the little girl to be careful before, have you ever been to this place?"

"Just kidding, I've never been to this place. The little black fat man shook his head and said with a wry smile, "Probably, probably only the dead will come here." ”

"Dead man, dead fat man, what do you mean by that?"

"What does it mean, of course, literally. The little black fat man glanced at the little black dog like an idiot, and then turned his head to Sun Haochi, who was also puzzled, and said, "When I saw the same stone carving on the wall of a certain tomb, what is the name of the place where we are located?"

The little black dog and Sun Haochi glanced at each other and said curiously almost at the same time.

"What's it called?"

"Hehe, if what the stone carving says is true, then we've come to a great place. The little black fat man stopped when he said this, and still didn't say everything about this place, this pass almost made Sun Haochi and the little black dog join forces to beat him, but fortunately, he was afraid of being beaten, and he didn't continue to pretend to be mysterious, and told what he knew.

According to him, he did not know how many thousands of years ago, he went to a mysterious tomb, there was no treasure in that tomb, there was only a wall full of stone carvings in the main tomb, and one of those stone carvings was exactly the same as the place where they were now, and the other was the same as the well above, but because of its age, there were many buildings around the well in the portrait, which was completely different from the jungle they had just seen.

And in the last few stone carvings, there is a sea of blood, this sea of blood is different from the sea of blood that Sun Hao entered before, the sea of blood he saw is relatively thin, and the sea of blood on the stone carvings is very viscous, and it also exudes a dark atmosphere.

As for what this place is called, where is it exactly?

The answers to these questions could be found in the last stone carving, which he remembered were engraved with four large and deep characters, 'Underworld, River Styx'.

Styx?

For these two words, Sun Haochi is not unfamiliar at all, even the elderly in China who are seventy or eighty years old, and children who are in their teens may have heard of it, this is the oldest place in Chinese mythology, and it is also a place that often appears in some fantasy or fairy tales.

"Little black fat man, are you sure it really says Underworld, Styx?" asked Sun Haochi with a strange expression.

Eat out an emperor
