The twilight was dreary, and the sky was full of light.

Looking at the forest of no return after the rain, a touch of autumn yellow is stained on the canopy of the forest, highlighting the power of late autumn.

The vicissitudes of life, the huge tree king, rumbling through the woods, walked towards the Fountain of Immortality under the ancient cliff of the Hero City. At this time, Liu Beishui raised his hand and released a pale silver wind spirit, which condensed into a beautiful wind spirit giant bird in mid-air, and then he and Ye Qingcheng, Fu Shan, Xiao Bian, and the dryland bear holding a huge tree king fruit flew over one after another, landed on the back of the wind spirit bird, and flew towards the ancient cliff in the distance.

The twilight after the first glow was short-lived, and then the sky quickly darkened. Twilight hung over the Forest of No Return, and a misty layer of evening smoke drifted over the lush canopy. A fading cloud in the western sky changed silently.

Under the last glow, the hero city on the ancient cliff has been bathed in loneliness for thousands of years.

After the outbreak of the First World War in Beihai, except for the Burning Sky Crocodile, the other strong people in the city have long been turned into bones and buried in the Beihai.

The city was empty, and its majesty and splendor, its hustle and bustle, and its life, were gone. Time has been barren here for thousands of years.

The ancient cliff more than 300 zhang high is like a huge long tongue, and the hero city is almost ten miles away, and it is located on the "tip of the tongue" of the ancient cliff. The city seems to be entrenched in the depths of the forest, looking at the whole forest from afar.

The ancient cliff is called the Watchman Cliff, which is a rare handsome cliff highland in the forest of no return. The Hero City occupies the best feng shui in the forest, with a good cliff on the top and a good spring on the bottom, and it is the first city in the Yuntian Continent thousands of years ago.

At that time, this city gathered the top heroes and heroes on the mainland, including imperial kings, hidden masters, unruly heroes, heavenly heroes, legendary heroes, etc., but once they entered here, they took off all their halos and became an "ordinary" resident. There are only one hundred and thirty courtyards here, and those who want to live here must be famous all over the world. It is said that the lowest cultivation among them has to be Emperor Wu.

However, after the outbreak of the Battle of Beihai, which changed the pattern of the world, almost all of the more than 100 emperors here were gone, and only one empty city adhered to their former glory.

All of them have been buried by time, except for the hottest fanatic at the beginning, the Volcano Ripper, the Burning Sky Crocodile, who still stubbornly lives here......

The flying spirit bird soared in the air, the cold evening breeze blew slightly, and now the hero city located on the ancient cliff appeared a scene that surprised everyone.

Looking down, this empty city, which has been eroded by wind and rain for thousands of years, actually lit up with red ancient lamps at dusk, rendering the whole city dark red. Moreover, the city is not dilapidated or deserted, it is neat and tidy, as if it were still inhabited yesterday.

"Sigh. Fu Shan overlooked the empty city, sighed on the ground, and said: "The predecessor of the Burning Sky Crocodile is also a stubborn character, people go to the empty city, but he still makes the city as clean as ever, and the heroes who are so difficult to die will come back?"

"It is said that the Burning Sky Crocodile is five hundred years older than the Cloud Beast King, has an epic legend like him been promoted to Shura in this thousand years?" asked Liu Beishui.

"This city used to be inhabited by all the masters known to the Burning Sky Crocodile, they were all killed in battle, he was tortured by loneliness for thousands of years, how could he still cultivate his state of mind? It would be good to be able to maintain his original cultivation. Fushiyama said.

"That's it. Liu Beishui pondered for a moment and said, "Then he also lived for more than two thousand years, almost at the end of his life." ”

Shura is the strongest above the hero, and the most powerful peak in the world, and then there are immortals. Although the lifespan of a hero is very long, it generally does not exceed three thousand years, and even two thousand five hundred years old is extremely rare.

"So, we're going to give it a go. Ye Qingcheng said: "I hope that the old-timers can pass on their lifelong fire spirit skills before they reach the end of their lives." ”

If he really thinks so, he has to go away from fire. Fu Shan said: "After all, Lihuo is a true fire heavenly demon that is rare in a thousand years. ”

In the evening, the forest gradually fades like a vast ocean. A bright moon rises quietly in the sky.

In front of this heroic city of the old times, an ancient statue stands. It is flush with the twenty-zhang high city wall, guarding in front of the ancient lacquer mottled city gate, it is the statue of the first city lord of the hero city - Qing Yu. It was dressed ordinarily, maintaining a modest posture with a smile on its face, as if welcoming the heroes of the world into the city.

There is no gate in this city, only a huge gatehouse, and its purpose was that those who come will not be refused, and those who go will not stay. Moreover, this is a city of heroes, inhabited by the top powerhouses on the mainland, and those who are roosters and dog thieves do not dare to come in to commit crimes, steal, or do other things like flies and dogs.

On the simple city tower, there are still three ancient big characters: Hero City.

"Duh, Duh, Duh, Duh, Du......" Several falling footsteps sounded, and Ye Qingcheng and the others flew to the west gate of the Hero City.

When they saw the ancient sculpture of Qingyu, they all bowed lightly in respect.

"It turns out that the legendary Hades Emperor Qing Yu looks so ordinary?" Liu Beishui looked at Qing Yu's sculpture with admiration.

"Do you have to be a tiger to show his majesty?" Fu Shan smiled, "Since he is one of the guardian spirits of our continent, the real terrifying thing is only known to those enemies who have fought with him. ”

"Why is he called the Emperor of the Underworld?" asked Ye Qingcheng as he walked.

Ye Qingcheng was lucky, not only had he seen Qing Yu, but the coat of arms on his body was also created by Qing Yu himself. Thinking of this, Liu Beishui couldn't help but derive a sense of pride in his heart, after all, his brother-in-law was the future guardian of the Yun clan secretly cultivated.

"Have you ever heard of the eighteenth layer of hell?" Ye Qingcheng asked.

"Nope. Liu Beishui shook his head.

"The eighteenth layer of hell is also called the small underworld, or the underworld. I don't know exactly where it is. Ye Qingcheng said: "However, my master said that it is the most dangerous place in the human world, and Uncle Yu is the second strong person in the world after the Green Fire Crane Ancestor to dare to go to the eighteenth layer of hell to cultivate and come out alive. After walking out of the eighteenth layer of hell, he formed an alliance with the Cloud Beast King, and the title of Hades Emperor was sealed by the ancestor of the Green Fire Crane. ”

With that, they entered the solemn gate of the ancient city and walked towards the city. This empty city, with a total of more than 130 courtyards, but only two streets, it intersects in a cross shape through the center of the city, leading to the south, north, east and west four gates.

On both sides of the streets in the city, there are refining shops, medicine shops, restaurants, auction buildings, and even top-level inheritance buildings (it is different from the Qing Building, which is the most noble restaurant established by the elves for bloodline inheritance, and it is regarded as the highest standard elf tavern).

The qiē here has been vacant for nearly a thousand years. There are only ancient stone lampstands, standing in front of every building and courtyard, exuding a dark red spiritual fire.

Walking here, Ye Qingcheng felt an indescribable loneliness and depression, sadness permeated his heart, and even under the light of this dark red ancient lamp, looking at the empty buildings and streets, there was a creepy feeling.

Suddenly, they found that there were many strange black marks on the streets. Each black mark is a miserable human print, and they appear on the bluestone slabs of the street in various terrifying postures, as if ink is spilling on them.

"These are all the marks of a person's body before his tragic death?" Ye Qingcheng muttered.

"I guess so. Fushan said: "After the city is empty, there will definitely be some unscrupulous people who sneak in here to steal treasures. However, with the Burning Sky Crocodile seniors, they have not been able to get away with it, and they will inevitably be punished for doing bad things. Under the blazing flames of the predecessors of the Burning Sky Crocodile, the corpses of these guys were directly incinerated, leaving only the indelible traces of the corpses. ”

"How do you know so much about this city?" asked Liu Beishui.
