Douluo: The blue phoenix cries loudly, and the wind whistles through the air

The battle reached its climax, the sand and gravel were soaked in blood, and the stench of blood, accompanied by waves of heat, assaulted the senses.

After pondering for a long time, Wu Qi finally said, "Once the city is fully revealed, we will go around it from the side and try to avoid direct conflict with other exiles."

More than the treasures of this place, he wanted to know its history and whether it was truly as recorded in the Spirit Hall.

Meanwhile, he had already planned his escape route before entering.

He has the ability to fly, and as long as the desert doesn't become overwhelming, he is definitely capable of escaping.

As the first rays of sunlight shone down in the early morning, the sandstorm in the entire Lost Lands, which was unusually severe, came to an end, and the sky was clear and blue.

Seeing everyone eager to try, Wu Qi reminded them, "Don't scatter. If the sand sea reburies this place, I can use my soul skill to take you away."

Chen and Hunter instinctively chose to believe him, not to mention Qian Gu Chang Kong and the other two.

At this moment, all the exiles in the surrounding area had entered and were instinctively gathering in the city center.

Wu Qi and his companions, on the other hand, strolled around the outskirts of the city.

This place has been buried by the sea of ​​sand for tens of thousands of years, yet the city's buildings are all as good as new, without any trace of the passage of time.

Wu Qi kept stopping and starting along the way, slowing down the pace of the group.

You should know that everyone was following his orders to ensure that they could evacuate in time when the desert reburied the area, and dared not stray too far from him.

At this time, he was loitering around, seriously affecting everyone's progress in the treasure hunt.

Chen was immediately dissatisfied and questioned, "Hey, what are you doing? There can't be any treasure here, can there?"

Wu Qi shook his head, brushed aside the remaining sand on the ground, and showed everyone: "This used to be a riverbed."

Mr. Chen was puzzled and asked, "What does this have to do with treasure? Who would throw treasure into the river?"

It cannot be ruled out that there are treasures in the river, but at most they would have been accidentally left behind by someone, and the amount would be far greater than that of a treasure vault.

Seeing that she was about to explode, Hunter quickly dissuaded her: "Don't rush. He probably meant that if we can determine where the riverbed leads, we can find the oasis."

They wanted to reach the oasis more than the treasure.

Wu Qi nodded and reached into his robes to take out a bulging, sealed bag.

The bag contained nothing but air.

Seeing this, the others did not understand what he was trying to say.

Wu Qi explained, “When we entered the Lost Canyon, I casually filled a bag with air. At that time, the bag wasn’t full of gas. It’s obvious that as we went deeper into the desert, the terrain beneath our feet was rising.”

“If the oasis is a high point here, or was once the mother river of this kingdom, then the source of this riverbed must be the place where the oasis is located.”

The air pressure inside the bag is the same as the air pressure where it came from; no matter how well sealed it is, it will always leak.

But the fact that it's so bulging right now proves that the air pressure around it is decreasing.

Previously, while traveling, the yellow sand blinded him, making it difficult to discern the terrain. But with this object, Wu Qi was able to deduce a great deal of information.

The capital city must be a prosperous place, with a water system running through it that provides enough water for the entire population.

Despite the changes that have taken place in the Lost Land, an oasis still exists.

Without a doubt, the oasis must have a large volume of water, and there must be tributaries flowing into the capital. Based on this, Wu Qi only observed the riverbed after entering the city.

Listening to his explanation, everyone was still confused.

Especially air pressure, which no one knew what.

Wu Qi had simply filled a bag with air on a whim, never expecting it to come in handy now.

He didn't offer much explanation for the crowd's questions. "By following the direction of the riverbed, we can roughly determine the location of the oasis."

Although the oasis is in the west, if you keep going west, you may not be able to find it.

After all, even a slight deviation along the way, amplified by distance, can lead to vastly different outcomes.

Chen shrugged: "Alright, investigate carefully, but don't forget our purpose."

……

Wu Qi walked along the riverbed, circling around the city, until noon.

What is certain now is that before this ancient city was buried, it already had a complete water supply and drainage system, which was even more advanced than that of the mainland today, and there were also underground sewage pipes within the city.

After all, tens of thousands of years ago in the Douluo Continent, the technology of soul tools had not yet been lost, and in terms of its level of advancement, it was definitely superior to that of today.

However, the pipes were covered by gravel, preventing them from entering the city.

"What's so interesting about these sewers!" Chen said, completely losing his patience, arms crossed.

Wu Qi smiled calmly, "The city has a perfect sewage system, which may very well be connected to the interior of the palace."

"If you encounter a sewage pipe blocked by a fence, that's most likely where the palace is."

"And have you heard of the underground trading market?"

"The increased height of city buildings indicates a highly complex underground pipe system. There might even be a former black market there, which could contain treasures."

"The fact that the sand is slowly being discharged from the pipes after being buried for so many years proves that the pipe design is very reasonable."

"Everyone, give it your all and let the sand dissipate so we can go in and explore."

Wu Qi had his own reasons for doing this.

First, the competition for treasures on the ground is fierce, and getting involved doesn't guarantee you'll get much.

More importantly, they were unsure whether any of the exiles were Soul Saints or higher.

Given their strength, it's uncertain whether they can survive facing such a powerful opponent.

Furthermore, the Spirit Hall may have taken all the treasures from this place tens of thousands of years ago, but it was not recorded, or Wu Qi's authority was insufficient to find the relevant information.

He felt that if an underground black market truly existed, the treasure might not have been taken away by the Spirit Hall.

The only downside is that they might not be able to notice what's above them immediately, leading to them being buried by the sea of ​​sand.

Upon hearing that there might be treasure, Chen became much more enthusiastic and said, "Follow behind me."

Her martial soul is the Mighty Demon Ape, and after activating her martial soul, her arm muscles become extremely developed.

They quickly shoveled sand with both hands, clearing a path in no time.

The underground pipeline system is like a maze.

Buried by sand for tens of thousands of years, the grime in the pipes had long been carried away by the sand, leaving them as new as ever, without any odor.

Soon, they discovered something was amiss.

The underground pipeline system is not entirely used for sewage disposal; after prying open the steel doors, they found underground tunnels used for passage.

There are streets and shops around the tunnel!
"How magnificent this city must have been before it was buried!" the crowd exclaimed.

A complete underground sewage system, plus an underground city system—Wu Qi had only ever seen all of this in the bustling cities of his previous life.

This shows how prosperous the Douluo Continent was tens of thousands of years ago. (End of Chapter)
