"Is this the gate of the underground palace, and if not, what is this door?" Xi Zhou muttered as he scratched the pattern on the door with a fish bone.

"Xi Zhou took out the Nine Star Map and took a look, maybe he could find any clues," Gami said lazily and casually.

"That's right" Xi Zhou hurriedly took out the nine-star map from his arms, Xi Zhou looked at the map for a long time, and still couldn't do it, for a few days, facing the folding stone door, Xi Zhou pedestrians were at a loss. Western Zhou was a little depressed, and Caitlin said when she saw this: "Don't worry, let's all recall the legend about the crossbow ancestor together, maybe we can find something"

"In the legend of the Crossbow Ancestor, the most impressive thing is the deeds of mending the sky, if it is true, the Crossbow Ancestor saved the beings of the Haotian Continent, after she was buried underground, what did she want to tell future generations the most?" Caitlyn continued

"Is it her mending the sky?" said Garmi

"No, it's the Heavenly Tribulation, the Crossbow Ancestor wants to warn us that it's the Heavenly Tribulation, it's the fire rain. The mausoleum was intact, but the roofs of the houses were burned by the flames. It shows that after the crossbow ancestor made up for the sky, another catastrophe occurred. At this time, the crossbow ancestor has been sleeping in the underground palace, and there is no crossbow ancestor in the world, so the mausoleum was destroyed, the creatures of the Haotian Continent suffered a lot, the mountains and rivers changed, the mountains and rivers changed, and the five tribes who survived may have wiped out all this memory in their minds because of the pain and psychological trauma. Xi Zhou said

"Even if it's a catastrophe, what does it have to do with this stone gate?" asked Gami puzzled

"Of course it has a relationship, the reason for the Heavenly Street is that there was a collapse in the Nine Stars, and a star land pressed towards the Haotian Continent, and the energy generated destroyed the time and space of the Haotian Continent, resulting in the Heavenly Tribulation," Xi Zhou explained

"Xi Zhou, you go on, I think you should know the answer," Tashi said

"The reason for the Heavenly Tribulation is the overlap of the stars and land, originally the nine stars have their own position, if the balance of the nine stars is destroyed, then there will be a heavenly tribulation, you look at the nine star map, which star is the most likely to produce the heavenly tribulation" Xi Zhou asked

"The one in the middle, because there are four connected to it," replied Gami.

Xi Zhou shook his head and said, "On the surface, it is the star in the middle, but what if the one-dimensional plane picture you see is a three-dimensional space?"

Gami, Tashi, and Caitlyn shook their heads in confusion, you look at this, Xi Zhou used the nine-star map to wrap the stone willow fruit in Gami's backpack, and the star in the middle was clearly revealed, while the other stars and lands all overlapped. Our Haotian Continent is likely to be one of these star continents crowded together, and the Kexian Continent should also be one of them.

"According to you, the three-dimensional space must be prone to catastrophe, so isn't there no solution at all?" Tashi said

"No, you're looking at this", Xi Wei said that he wrapped the cup in his hand with a nine-star map, and the nine-star map and the nine stars were still clearly visible.

"No, according to you, your presentation is actually a two-dimensional," Tashi said

"Yes, then what do you look at this" Xi Zhou raised the cup horizontally

"Isn't this still two-dimensional?" replied Tashi, puzzled

"Then what if both vertically and horizontally move," Xi Zhou's eyes showed a strange brilliance

"Yes, it's three-dimensional, it's three-dimensional," Tashi said

Gami nodded as if he didn't understand, and said, "I seem to be able to understand a little, but how to make the stone door open?"

"Tashi, go and unlock the mystery of this stone gate, the star in the middle is the key." Xi Zhou said, I saw Tashi fly to the middle of the stone gate, hit it with a hammer, and then flew out from the left side of the door, around the back of the door, hit the symmetrical star again, and then flew back to the front of the door from above, and then on the right side, after the detour door again, knocked on the symmetrical star, and then flew down, and then knocked on the one under the middle star, only to see that the knocked star suddenly opened, Tashi flew back from behind the door, knocked on the middle star again, only heard the sound of clanging, the stone door opened inward, and the eyes of the four people were bright。

Garmi took out the marble chip from his backpack and handed it to the crowd, the marble chip has the effect of filtering light. Bringing the marble slices, Xi Zhou saw the scene inside the door. There are two parallel burial ditches on both sides of the spacious Yongdao in the underground palace, there are many animal bones in it, there is a pair of ear chambers on both sides of the Yongdao, only the entrance can be seen, and the inside can not be seen, at the end of the Yongdao, there are entrances on both sides of the left and right, which should be two side rooms. Standing outside the door, you can see the structure of the underground palace, only like this. Xi Zhou looked at everyone and said: "If anyone regrets it now, it should be too late" The three looked at each other, and none of them spoke, "In that case, let's go in together" After speaking, Xi Zhou once again took Tashi and Caitlin's hands, just like the last time he went to Aganzan to visit the Earth Rock Imperial City, Gami was a little disappointed, and at this time, Caitlin took the initiative to take Gami's hand, and glanced at Gami with a smile, which made Gami moved, surprised, surprised, and excited.

The four of them stepped into the door and stepped firmly on the ground drill of the road. The heart he was carrying finally fell to the ground, and the atmosphere didn't dare to come out of the four people, and he didn't even know if he could breathe in the dungeon, Gami took a deep breath and spit it out.

"It turns out that inside the dungeon, it's not what we imagined," Garmi said

At this time, Laika was guarding the fifth fork in the petrified forest, which was the location of the space-time ore vein, and suddenly the scene in front of Laika's eyes shook a little, and the surrounding scene seemed to have been extracted, constantly twisting and concentrating like the ore vein, Laika knew that the space-time shackles had been restored, and they had also entered the underground palace in the Western Zhou. Laika breathed a long sigh of relief and thought to herself, "At least for now, the Haotian Continent is safe for the time being."

Standing on the road, the four of them, you look at me, I look at you, since they were so excited that they couldn't move their legs, Xi Zhou said to Caitling: "You pinch me, see if I'm dreaming" Caitlin pinched Xi Zhou's arm vigorously, and Xi Zhou whispered: "Light, light." ”

The four of them calmed down, and Xi Zhou carefully observed the bones of the animals in the burial ditch, you see, there are common domestic animals here. There are also some living bottles and jars. The four of them cautiously walked forward, and after a fifth of the passage, the entrance to the ear chamber appeared. The four of them stopped, looked at each other, looked at the entrance of the ear chamber on both sides, and looked at Xi Zhou at the same time, and Xi Zhou immediately decided: "Go to the left first." ”

The four people enter the ear chamber on the left, the ear chamber is in the shape of a hollow shape with stacks, and four candlesticks are placed in the east, south, west and north corners of the stack, and there is a sarcophagus in the middle, and the coffin is carved with a horizontal fish.

Seeing this, Gami said, "What kind of fish is this, why haven't I seen it?"

Xi Zhou replied: "This is a cross-fish, which is said to have been born in Shihu Lake, and this lake is not frozen. Seven or eight feet long, shaped like a red carp, it is in the water during the day and turns into a human at night. If you can't pierce it, you can't boil it to death, and you can boil it to death if you boil it with two black plums, and you can go to evil diseases if you eat it. ”

"Why is this thing carved into this coffin?" asked Gami continued

"I don't know, but we'd better not touch these things," Xi Zhou said, seeing that there was nothing special in the ear chamber on the left, so the four of them retreated and entered the ear chamber on the right.

The ear chamber on the right is circular, and there are still stacks, and under the stacks, at the position of one-third of the arc, three candlesticks are placed, and there is also a sarcophagus in the middle, on which a winged fish is drawn, and Gami asks, "What kind of strange fish is this?" Xi Zhou replied: "This is a winning fish, the body of the fish and the wings of the bird, the voice is like a mandarin duck, and the legend says that if it appears, it will be flooded."

"The coffin in the underground palace of this crossbow ancestor is full of fish patterns, is it true that the crossbow ancestor was originally a fisherman, or does she like to eat fish?" Gami muttered to herself.

"I don't know, don't talk nonsense, this is the crossbow ancestor's underground palace," Tashi reminded Garmi

The four of them respectfully withdrew from the ear chamber on the right and continued to move forward along the road, when suddenly Xi Zhou remembered something, quickly turned around, and found that he didn't know when, the stone door behind him had been closed.

"Could it be that someone closed it, or did they touch some mechanism," Xi Zhou thought to himself.

Caitlin also noticed the strangeness of Shimen, but she nodded, saying that it was useless to make a fuss now, it was better to go in and move forward, Xizhou understood Caitlin's painstaking work, so she did not continue to worry about Shimen. Coming to the end of the road, there are forks on the left and right sides, if the Western Zhou is not wrong in speculation, this is the intersection of the left and right side rooms. Xi Zhou tilted his head to the left, so everyone followed Xi Zhou, and walked to the left Yongdao, every 10 meters on the Yongdao, there will be a candlestick, about 200 meters, they found the entrance to the side room. Xi Zhou stood at the door of the side room, turned out the flint from Gami's backpack, lit a ball of kapok, and then threw it into the side room, and with a "bang" the kapok exploded leaving only a wisp of green smoke. This scene, frightened Gami, took a deep breath.

"This side room can't be entered, and some of the gases in it are highly flammable, and we probably don't even have bones left when we go in," Xizhou said

"There is no door in this side room, so why is the gas inside not leaking outside?" asked Tashi

"It should be the air inside the dungeon, repelling the gas in this side room, sealing it in the side room, if you don't take the initiative to go in, the gas in it won't come into contact with us," Xi Zhou explained.

"Then let's go to the side room on the right," said Garmi. The four of them returned to the end of the road, this is Xi Zhou looked at the back again, and the stone door that was closed just now opened again. Xizhou was very strange, but the opening of the stone door made Xizhou's heart feel a little more secure.

The four of them traveled another 200 meters to the right to the entrance of the side room on the right. The old trick of the Western Zhou Dynasty was repeated, and the kapok was thrown in, and the kapok slowly fell to the ground and burned out slowly, the Western Zhou took a look, put away the flint, nodded and said, "There should be no problem with the air here." Let's go in and see."
