Following the dark and narrow tunnel, gusts of cold wind blew across his cheeks. Yang Yu was at the front of the team as the forward, Bai Jin followed closely behind and used magic to illuminate the way forward. Oias was behind the end of the team.

This tunnel has a certain slope, allowing Yang Yu to penetrate into the ground smoothly, and Bai Jin emits a faint light. Although it cannot illuminate the deep darkness, it is enough for Yang Yu to see what is ahead and prepare in advance.

The team was moving very slowly, and they were careful every step, and it took some time to reach the end of the tunnel.

Jumping down from the hole of the landslide, Yang Yu stood steadily in the underground passage made of blue stone slabs.

Immediately afterwards, Oas and Bai Jin also landed steadily into the spacious passage. With the help of the lights emitted by magic, they looked at the entire passage curiously.

The entire passage is as wide as five carriages, with a height and width, and is a square passage. This passage is mainly made of cyan and white stones, with a natural beauty that is natural.

The walls on both sides of the passage are colorful colors intertwined with each other, and are painted into exquisite murals.

Touching the slightly lit ground gently, Oias felt that this kind of place seemed familiar,

"What exactly is this place? Could it be, it is also a kind of underground maze?"

Looking through the strange mural, Bai Jin denies Oias's idea,

"It's more like some kind of ancient ruin than a dungeon. If it's an underground maze, there should be a special magic fluctuation, but I know I haven't sensed it now."

Yang Yu opened the system panel and no new tasks jumped out on the task interface.

In the past, when you entered the scope of the underground maze, the task of attacking the underground maze would jump out of the task interface, but this time there was nothing.

Either this dungeon has been guided by others, or as Bai Jin said, this is an ancient ruin.

In the game, ruins are places where dangers and opportunities coexist. They may have countless treasures and experience values. Correspondingly, the danger is also extremely high. Various powerful monsters and powerful mechanisms are just commonplace.

However, it is also possible that like real ruins, it is in ruins, and all the treasure traps are taken away, leaving only a series of ancient traces.

Walking to the center of the passage and looking at the murals on the left and right sides, Yang Yu tried to go deep into the depths of this ruins.

The images drawn on the mural are a little abstract, but they do not affect reading at all. Even if you start reading from the middle, you can understand what the mural says, and you can also find the direction of the channel from the narrative of the mural.

The mural on the first floor of this ruin shows the story of a slash-and-burn civilization gradually growing into a feudal kingdom with emperors and systems.

At the entrance to the second floor, the story of the mural takes a dramatic turn, and countless people gather to overturn the king's throne.

Following the second floor of the stairs, Yang Yu and the others entered the second floor.

In this layer, thick black air permeates the passage.

These black gas are harmless, but they are simply spreading in the passage. Even if Yang Yu and the others pass through the black gas, they will not feel any discomfort.

His eyes continued to browse the murals on both sides of the passage. Yang Yu was surprised to find that after people overthrew the king, they ushered in a brief peace. Then smoke of gunpowder rose everywhere, colliding with each other, bursting out the light of wisdom, and developing various technologies. Yang Yu even saw technology similar to tanks and aircraft on the murals.

At the end of this layer, a great war broke out between civilizations, and this is the murals on this layer that did not give the result of this war.

Want to know the subsequent development, Yang Yu couldn't wait to enter the third floor.

In the third layer, black liquids like bubbles occupy the channel. These clusters of black liquids are exactly the same as what Yang Yu and the others saw, and the corrupters before they turned into black creatures.

The difference is that these black liquids really squirm slowly as if they have their own thoughts without any cores.

Open the panel and each black liquid that will squirm has three big question marks. I don’t know the name, but these black liquids have their own attributes and blood bars.

Yang Yu carefully knocked down one, and these slimes immediately turned into black gas and dissipated in the passage. After a while, they did not turn back into the entity, as if they were really dead.

Telling Oias and Bai Jin behind him to be careful, Yang Yu began to open the way, waved his sword, and killed all the black liquid like black slimes.

The murals on the third floor do not explain the result of the war. They show that all civilizations work together to become one civilization, and technology has completely taken off. From the beginning of the third floor to the end of the third floor, nearly two-thirds of the space is talking about the greatness of their technology. Yang Yu even saw the spacecraft floating outside the planet.

But when we arrived at the entrance of the fourth floor, the style of the mural suddenly changed.

A huge giant held all the shining stars in his hands, and the spaceship that was proud of civilization was like an ant in front of the giant.

This civilization met God.

Careful of subsequent development, Yang Yu immediately entered the fourth level.

But on this floor, the content on the mural came to an abrupt end.

It is not that the mural does not tell the following content.

However, the mural seems to have been corroded by something. When you see the contents on the mural, you can only see the tip of the iceberg of time from the scattered fragments.

In this layer, not to mention that there is no black liquid like a slime, even the black gas is gone.

The same situation also occurs on the fifth floor.

The fifth floor mural was also corroded by something, and it was impossible to know what the mural said, and there was no black air in it.

In desperation, Yang Yu and the others had to come to the last floor.

The sixth floor of this ruin is a huge circular altar with ancient characters that Yang Yu and the others did not recognize, forming a pattern similar to a magic circle.

In the middle of the ancient altar, there is a holy grail full of amethyst. This holy grail is made of stone and looks simple to serve amethyst.

"This is the center we are looking for."

Yang Yu pointed to the magic circle in the center of the altar, very sure.

"Will it be a little too smooth?" Ias felt a little strange, "I think it's only been an hour or two to arrive at this ruins, and we arrived at the last floor without any trouble."

"Smoothing is not a bad thing. But...it seems that this is just the tranquility before the storm."

"What's the meaning?"

Yang Yu did not say it clearly, but just threw the scroll to Bai Jin, asked her to open the scroll, and placed the scroll on the Holy Grail in the middle.
Chapter completed!
