The deadly, silent, and dark River Styx, like the eternal black silk of death, lies quietly in the ground, as if there is nothing with a strange black glow. Pen & Fun & Pavilion www.biquge.info

"Where does this river Styx lead, hell?" Nanas's breathing was a little short, she had been burning all the black gas near her mouth and nose with the Flame of Extermination, but this also brought her some trouble, the oxygen in the ground was already very small, and if she burned it like this, it was naturally much less.

Jing Qi felt Nanas's anxious mood, but there was nothing she could do.

He himself relied on the mysterious black pendant to ignore these black gases, and he took a big breath of not much oxygen.

"If you can't hold on, you can go to the exit and wait for me." Jing Qi suggested.

"No!" Nanas knew that the Holy See was still ahead, and thought to herself that even they could hold on, so what reason did she have to give up?

Of course, if Nanas knew that the Holy See had two gas masks in their hands, her psychological shadow area would probably become one of the top ten math problems in the world.

Drink some water when you're thirsty, eat some beef jerky when you're hungry, and take a nap in place when you're sleepy, Jing Qi and Nanas have been following the people of the Holy See for two days, and what makes them wonder is that after two days, the surrounding situation seems to be unchanged.

The dead and silent river Styx, with its narrow passages on both sides, didn't even seem to change in size.

"I have a sense of foreboding." Nanas hugged her arms and trembled.

"yes." Jing Qi's face was solemn, "This Styx River seems to have been built by man. ”

Nanas: "You think so, too?" ”

"Well, from the time we came down to the present, the width of this river Styx, and the width of the passages on both sides, are as accurate as if they had been measured with a ruler, and this could never have been formed naturally."

The rivers in nature, from small streams to the Yellow River and the Yangtze River, cannot maintain an absolute width in their river widths, such as the width of the river surface of the Yangtze River, which is large and small, and it is impossible to be consistent!

But this underground river Styx, it did.

Nature's work?

Jing Qi didn't believe it anyway.

"We've gone deep into the ground for I don't know how many meters now, but the oxygen content here hasn't increased or decreased." Nanas also voiced her findings, "It's like someone designed it on purpose!" ”

The more the two of them talked, the more frightened they became, knowing that this was not on the ground.

Here, it's underground.

If the meaning of the existence of the ancient underground civilization ruins above the Dark Abyss is to sacrifice the dark serpent living in the Dark Abyss, then who built this Styx River that exists below the Dark Abyss?

Such a huge project is absolutely impossible to be completed by a few people, it is simply a fantasy!

The two of them had no clue, but what they could confirm was that the history of this river Styx definitely exceeded the history of the underground civilization on the dark abyss.

Nanas suddenly hesitated and said, "Jingqi, I have checked the information about the Dark Serpent and the Earthly Python before. ”

"Oh, what's the discovery?" Jing Qi once saw the earthly python under the ice seal of the North Pole, that guy, it was too big, one head almost filled the ice pit of two hundred square meters, if it was allowed to stretch out, it was estimated that the snake body would be at least a few thousand meters!

Nanas said: "The earthly python and the dark giant snake, collectively known as the world-destroying 'python' and 'snake', have the powerful strength to destroy the world, but, according to the discoveries of today's archaeological community, the largest and longest python living on the surface of the earth, the titan python, only grows to 50 feet (about 15 meters), but whether it is the dark giant snake or the earthly python, their length is far greater than the titan python!" ”

"So ......" Jing Qi blinked his eyes twice, can he believe the words of the archaeological world, he is a little bottomless, after all, in the archaeological world of the Yan Kingdom, there is not the slightest information about the ancient five clans.

"So I suspect that neither the earthly python nor the dark serpent are species on the surface of the earth!" Nanas exclaimed, "They, maybe they're species from the underground!" ”

"Underground? What are you playing ......" Jing Qi was just about to refute, and he was shocked in his heart, because where he was now was not on the way to the underground, especially that there was a river Styx next to him!

"You mean, the earthly python and the dark serpent swam up from the depths of the earth through this river Styx?" Jing Qi's eyes widened, and he was so shocked that he swallowed three mouthfuls of saliva in a row, oh no, the fourth mouthful.

Nanas nodded: "Yes, if I guessed correctly, then at the end of this river Styx, there is an unknown underground world!" ”

"The Underworld?" Fifth mouthful of saliva.

Nanas's eyes flashed with excitement, excitement, fear, and fear: "The earthly giant python and the dark giant snake on the surface of the earth may be the existence of a giant Mac, and even have the power to destroy the world, but in the underground world, there may be countless earthly giant pythons, countless dark giant snakes!" ”

The sixth gulp was swallowed.

"Of course, it is also possible that in the passage of time, the earthly python and the dark serpent of the underground world have been annihilated in the long river of history." Nanas said.

Jing Qi suddenly remembered one thing at this moment, that is, the mysterious black pendant around his neck.

He had discovered that the pattern on one side of the black pendant was similar to the 'snake path' left behind by the Dark Serpent after swimming in the Dark Abyss.

At the time, he thought it was a coincidence, but now it seems that this mysterious black pendant is very likely to have something to do with the dark serpent!

If the Dark Serpent really swam up from the ground through the River Styx as Nanas guessed, then it would definitely not be harmed by the River Styx, otherwise the Dark Serpent would have been corroded into slag by the water of the River Styx before it could swim up.

It just so happens that this mysterious black pendant can also help Jingqi be immune to the corrosive and poisonous damage of the River Styx!

"Looks like we've discovered something amazing." Jing Qi's heartbeat accelerated, "We won't be killed, right?" ”

Nanas rolled her eyes and continued, "Jingqi, have you ever wondered why the Black Emperor came here? ”

Jing Qi was dumbfounded: "You mean, the Black Emperor knows that this Styx River can lead to the underworld?" ”

Nanas nodded: "Otherwise, why did he come all the way here?" Tourism? Explore? ”

Jing Qi frowned, the Black Emperor is one of the five ancient clans of the Yan Kingdom, the inheritance emperor of the Shui Clan, but don't forget, Jing Qi is also one of the five ancient clans, the heir of the Qing Emperor of the Mu Clan, if it is said that Mi Xin, it makes no sense that the Water Tribe's side has passed it down, but the Qing Emperor of the Mu Clan will not pass on the truth.

"Wait!"

Jing Qi's eyes lit up, and he seemed to remember something.

Mirage!

The spirit beast mirage of the water tribe!

The five ancient clans, except for the Black Emperor of the Water Tribe, no one knew the specific origin of the mirage, which was a mystery at the time, and even more so now!

What if the mirage also swam up from the underworld via the River Styx?
