The fourth wall is likewise a single stone slab relief. The main body of the relief is a castle. The interior of the city is laid out in a checkerboard style, with six avenues running from south to north; It runs ten avenues from east to west. Among the streets and alleys that extend in all directions, there are some palaces scattered around. Centered on various palaces, the surrounding houses are lined up. On the main roads in the city, there is a lot of traffic. The markets on both sides of the main road are crowded with pedestrians.

The scale of the whole city is huge, judging from the number and distribution of buildings in the city, the city has a radius of hundreds of kilometers.

"The layout of this city, as well as the degree of prosperity, is a bit like a metropolis in the Tang and Song dynasties. However, there has never been a city of this magnitude recorded in our history books. It is even more impossible abroad. Like the reliefs on the other three walls, these details are so real that no one can imagine them out of thin air. So, these are real beings, or ever real beings. Ye Feihua said.

"I think so too!" He Shannon nodded and said, "This city is very ancient, a bit like that prehistoric civilization. I have a vague feeling that it is very likely that the city itself is a kind of record of some kind of prehistoric civilization. I was thinking that once this stone chamber was born, it would definitely cause a global sensation. This stone chamber is sure to become the most famous relic in the world. ”

Ye Feihua and He Shannon walked to the wall as they spoke, and began to inspect the wall.

Ten minutes later, the two men looked at each other again, speechless. The bottom of the relief is tightly sealed, and there are no secret doors or passages at all.

"The man who built this stone chamber has to go out, right? Since there is no passage behind the wall, it is likely that the exit is hidden somewhere else. I don't believe I can't find an exit. Come on, come on, let's move on. Ye Feihua said.

At that moment, Ye Feihua and He Shannon worked together, and carefully checked the ground paved with white marble and the steps of the four-sided ladder-shaped platform.

As a result, still nothing.

After the check, almost an hour passed. Ye Feihua and He Shannon stood at the top of the four-sided ladder-shaped platform, and the two of them looked at the strange long sword in the middle of the top.

"Perhaps, that slightly evil sword is the key." Ye Feihua said.

Ye Feihua walked over as she spoke, and stood at a distance of about half a meter from the long sword.

This time, Ye Feihua was very close, but she didn't have the feeling of palpitations before.

Ye Feihua stared at the long sword for a while, then held the tiger tooth in his hand and slowly reached for the bone hilt of the long sword.

10 centimeters, 5 centimeters, 1 centimeter......

As soon as the tip of the tiger's tooth touched the hilt, a monstrous chill and murderous aura suddenly burst out from the long sword.

That chill and murderous aura seemed to have substance, and Ye Feihua froze after a moment of excitement.

Then, I saw that an ice mist wrapped around Ye Feihua's arm in an instant, and spread rapidly towards Ye Feihua's whole body.

He Shannon had been concentrating on guard, and although he was shocked when he saw this situation, his reaction was not sluggish, and almost at the same time as the ice mist wrapped around Ye Feihua's arm, He Shannon waved the King of the Jungle and flicked towards the tiger tooth on Ye Feihua's hand.

"Ding!" The King of the Jungle slammed into the tiger's fangs and let out a metallic thump.

Fortunately, this light knock finally caused the tip of the tiger tooth to leave the hilt, and the ice mist spreading towards Ye Feihua's body quickly disappeared.

However, at the moment when the tip of the tiger's tooth left the hilt, a transparent light wave visible to the naked eye emitted from the long sword.

"Poof!" Ye Feihua and He Shannon were hit by that light wave at the same time, and the two of them flew out directly and fell the steps of the high platform. Because the impact was so amazing, the two of them rolled down the steps again, and finally rolled on the ground several times before they came to a complete stop.

Huya and the King of the Jungle also threw out, and a "clanging" sound rang out in the stone chamber.

Soon, however, silence returned to the stone chamber, and it became a deathly silence.

Ye Feihua and He Shannong were lying on the ground, motionless.

I don't know how long it took, but He Shannon moved, trying to roll over and get up.

However, He Shannon tried several times in a row, but without success.

"Your uncle! It hurts me! He Shannon was angry and scolded.

After He Shannon scolded for a few words, he remembered something, struggled for a while, and finally staggered up.

"Kitten, are you alright?" He Shannon exclaimed urgently.

"I'm fine!" Ye Feihua was lying not far away, her nose and face swollen.

After hearing He Shannon's shout, Ye Feihua moved, and then, moved again.

"This is too evil! I don't understand! What a hell of a life! By the way, you hurry up and check, in this hellish place, if there are parts on your body that are broken, it will be a big trouble! Ye Feihua said annoyedly.

"That broken sword is indeed evil! It actually sent out a shockwave like **! Or a visible shockwave! He Shannon said.

He Shannon glanced at the top of the high platform, then grinned and said with a smile: "I have rough skin and thick meat, and falling from it is just a trivial matter, I can't hurt my tendons or move my bones." Kitten, I'm worried about you, what happened to you just now is too scary! ”

"It's fine! Huya will be fine without the hilt. Falling from it didn't hurt my muscles and bones. Only this time I fell too hard and almost had a concussion. However, lie down for a while and you'll be fine! Ye Feihua smiled.

He Shannon took a few steps forward and lay down on his back beside Ye Feihua.

The two men stared at the dome, both motionless and silent.

After lying like this for five minutes, Ye Feihua spoke: "The wall, the ground, and the high platform, we have all checked it. Now there are only two places left, the dome and the aperture. If there is an exit, it is unlikely that the exit will be located in the dome, and it will most likely have something to do with that aperture. ”

"How? Are you able to move freely? He Shannon turned his head to look at Ye Feihua.

"No problem!" Ye Feihua stretched her arm and said, "It's been a few hours now, there is neither food nor drinking water, if we can't find the exit, we will be trapped here alive." In addition, we don't know what the situation is outside, and even if we get out of trouble, we have to ensure that we have enough physical fitness to prevent emergencies. So, we need to hurry! ”

At that moment, Ye Feihua and He Shannon got up with a bone, and the two of them picked up their respective sabers, and then walked quickly to the front of the orange aperture.

The aperture is one meter in diameter, and there are twelve twisted and intertwined lines in the circle. There are some strange runes strung together along the lines. Apertures, lines, and runes all shone with a faint glow, and every now and then a rune would suddenly become bright, and then slowly dim.

He Shannon approached the aperture, leaned down, and began to study the lines and runes in the aperture.

Unexpectedly, it was not even five seconds before He Shannon put his head above the aperture when another situation occurred.

I saw that the orange aperture suddenly shone brightly, and then, the lines in the aperture twisted rapidly.

At the same time, the runes on those lines also bloomed with blazing light.

Immediately afterward, a suction force suddenly came out of the aperture.

He Shannon was caught off guard, stumbled, and fell down directly.

Ye Feihua always remained vigilant, seeing that He Shannon was about to fall in the aperture, Ye Feihua grabbed He Shannon's arm and dragged it back.

However, the suction power emanating from the aperture suddenly increased, and He Shannon still fell headlong.

Because Ye Feihua grabbed it too tightly, He Shannon took Ye Feihua hard when he planted it, and as a result, Ye Feihua also lost her balance and fell into the aperture.

Ye Feihua and He Shannon reacted very quickly, and before the two of them could fully touch the ground, they supported the ground with one hand, ready to roll over and roll out of the aperture.

However, the light on the aperture then spun at high speed and rose upward, forming an orange spiral of light. Ye Feihua and He Shannon only felt that the world was spinning, and they found that they were completely wrapped in a cloud of orange light, like a silkworm cocoon, tight.

Ye Feihua felt like a cloud, her body was completely out of the control of her brain, and she seemed to be unable to do anything except clutch to He Shannon's arm.

As for He Shannon, after struggling violently, he grabbed Ye Feihua's camouflage uniform with his backhand.

"! ......" Ye Feihua opened his mouth and shouted.

Ye Feihua's face changed as soon as she spoke. Because, Ye Feihua couldn't hear her own voice, let alone He Shannon's voice. An inexplicable fear immediately surged out of Ye Feihua's heart.

I don't know how long it has been, and I don't know what happened, Ye Feihua only felt that her body was stunned, and her feet seemed to be on the ground.

Not allowing Ye Feihua to react, He Shannon had already fallen down by relying on Ye Feihua, and Ye Feihua stumbled.

At the same time, the orange light that wrapped Ye Feihua and He Shannon disappeared and was no longer visible.
