The sudden change in the sky not only alarmed everyone in the Flame City, but even everyone within the 108,000 miles covered by dark clouds was alarmed, this dark cloud came too fast, and the clouds were also filled with an extremely large energy fluctuation, forming a terrible pressure that made everyone almost out of breath, everything seemed too unusual.

In the City Lord's Mansion of Flame City, Youyue, Bi Lian, Bi Hai and several Saint King powerhouses were all standing outside the main hall looking up at the sky, their expressions full of surprise, this dark cloud was strange, and they couldn't figure out what was going on.

In the silver-white Haoyue Temple, the favorite figure of the Haoyue Fairy was sitting cross-legged in a secret room, and suddenly, her closed eyes suddenly opened, staring at the top of her head, although she was hiding in the Haoyue Temple, her gaze seemed to be able to see through the obstacles to see the scene outside.

"It's... This is the Heavenly Tribulation, the Heavenly Tribulation usually only appears in the Holy Realm, and rarely appears in the Nether Realm, could it be that something remarkable has been derived from this Realm?" the Haoyue Fairy muttered to herself, the light in her eyes flickering.

Bi Hai stared at the rapidly rotating whirlpool in the center of the dark clouds for a while, and then said to Youyue and Bi Lian: "It's not normal there, I'll go over and take a look first, you guys take care of yourself." With that, Bihai flew towards it alone.

"Grandpa be careful!" Bi Lian shouted loudly in the rear, her tone was full of concern, a pair of phoenix eyes stared at the huge whirlpool in the center of the dark clouds, and then seemed to feel something wrong, and said to Youyue: "Sister Youyue, this dark cloud is too weird, I'm afraid that something will happen to Grandpa Zu, you better take me over, I still have the jade burning stone left for me by my brother, which can exert the power of the Holy Emperor's Great Perfection, and can play a great role at the critical moment." ”

Youyue nodded, and flew behind Bi Hai with Bi Lian's little waist in her arms, now Bi Lian's strength is not as strong as the Sky Saint Master, and she can't fly in the sky at all, so she must get Youyue's help.

At this moment, the silver-white light flashed away, and I saw the Haoyue Temple fly out of the City Lord's Mansion, blocking the way of Youyue and Bilian.

"Disciple, you can't go over, just stay here, this is not an ordinary dark cloud, but a heavenly tribulation, once you are involved in the thunderstorm, even the Holy Emperor will die. The voice of the Bright Moon Fairy came from the temple.

Youyue and Bilian didn't know what the Heavenly Tribulation was, but after listening to the words of the Haoyue Fairy, the two of them were suddenly pale with fright, and said anxiously: "Master, Grandpa Bihai has flown over, you hurry up and call Grandpa Bihai back, you must not let Grandpa Bihai have anything to do." ”

A band of light condensed entirely from the moonlight flew out of the Haoyue Temple, and the speed was incredibly fast, and in an instant, it caught up with Bi Hai, wrapped around Bi Hai's waist and directly pulled him back.

Bihai knew that this was the behavior of the Haoyue Fairy, so he did not resist, and let himself be pulled back by the light belt, and just wanted to ask the doubts in his heart, he heard the voice of the Haoyue Fairy coming from the temple: "All of you must not approach the center of the thunderstorm, otherwise, even if you have the strength of the Holy Emperor, you will be dead or alive." ”

If this sentence came out of someone else's mouth, they would definitely sniff it, and no one would think that a strange dark cloud could actually make the Saint Emperor powerhouse fall, but the person who said this was the Haoyue Fairy, so no matter how exaggerated it sounded, they couldn't help but believe it. After listening to the words of the Haoyue Fairy, Bi Hai's face suddenly changed, and there was a hint of fear in his eyes when he looked at the thunder.

At this time, the space dozens of miles away fluctuated violently, and the doors of space quickly cracked, and a large number of Saint Emperor powerhouses came out of it, including many Saint Emperors.

A large number of strong people who rushed from the mercenary city also came to this area at the same time, but as soon as they came here, they quickly flew towards the location of the tungsten alloy vein, and finally stopped ten miles away from the whirlpool in the center of the dark clouds, staring at the huge whirlpool that was spinning quickly with solemn faces, and they didn't dare to act rashly until they figured out the situation.

"Strange, what happened here, why did such a big dark cloud suddenly come out, this dark cloud is full of strange ......"

"This doesn't look like a passage to the Holy Forsaken Realm......"

"The energy contained in this dark cloud is too strong, my strength has reached the Holy Emperor Seventh Heaven, but I still feel a thrill ...... my heart."

Many of the Holy Emperor powerhouses who had arrived from the City of Mercenaries gathered together to talk about this strange dark cloud, and several bold Holy Emperors were already heading towards the whirlpool.

The Haoyue Temple flew over from a distance, exuding a layer of pure moonlight around his body, and the cold voice of the Haoyue Fairy came out from the temple: "This is the Heavenly Tribulation, it is very rare here, under the whirlpool is the sensing range of the Heavenly Tribulation, once you step in, you will be locked by the Heavenly Tribulation, even if there is a Holy Emperor among you, there is death and no life, and in the end you will only end up with the destruction of the form and the gods. After the Haoyue Fairy warned everyone, he controlled the Haoyue Temple to hover on the other side, twenty miles away from the Heavenly Tribulation sensing range.

"Heavenly Tribulation, what is this?" All the Holy Emperor powerhouses were puzzled, they had lived for thousands of years, heard many strange stories in the world, and even some people had a clear understanding of some things in ancient times, but they had never heard of the Heavenly Tribulation in the mouth of the Haoyue Fairy.

This was true even for the Ten Guardian Families, which had a long tradition, a term that was very unfamiliar to them, as there was no record of the Heavenly Tribulation in the ancient texts of their family.

"Haoyue Fairy, may I ask what this Heavenly Tribulation is?Why does it appear?What does it portend?How do you know that this is a Heavenly Tribulation?" A Supreme Elder who was guarding the family asked, his tone calm, treating Haoyue Fairy as an equal person to himself, after all, Haoyue Fairy was now only a primordial god, and the deterrence caused to them was far inferior to that of a living Saint Emperor.

Artie Blue Devil, the three Holy Emperors of the Beast Clan and the Dao Master of Human Desire all stared at the Haoyue Temple, the casting material of the Haoyue Temple was taken from the distant Moon Star, which was very rare and precious, even if the Holy Emperor was strong, he might not be able to have it, because it was too far away from the Moon Star, and it was impossible to build a space gate in the outer void, if you wanted to rush to the Moon Star, the only way to fly over it.

The Haoyue Fairy didn't say a word, whether it was the thousands of Holy Emperors in the field, or the Five Great Saint Emperors, none of them received her attention, she drove the temple to come here in person, just to witness what caused the Heavenly Tribulation.

"Oh my God, what did I see, there is a city completely made of tungsten alloy, this is tungsten alloy, purely in terms of weight, it is much more precious than purple gold coins, such a large city, how much precious tungsten alloy does it cost." "A Terran Holy Emperor from overseas discovered the Flame City in the distance, and immediately let out an exclamation, his eyes lit up.

Hearing this, some Terran Saint Emperor powerhouses who were also from overseas suddenly turned to look at them, and this look immediately straightened their eyes.

"It's really incredible, it's really a city completely made of tungsten alloy, as long as you have this city, you will definitely become the richest and most noble person on the Tianyuan Continent, hey, my eyes don't send, there is no formation to protect in that city, and there is also no protective barrier, and the Holy Emperor has no one, it seems that it was occupied by a mercenary group of average strength. Another Terran Holy Emperor from overseas let out an exclamation, his eyes full of fire.

Although money is nothing to the Holy Emperor's powerhouse, if this wealth is incredibly large, it can still cause many Holy Emperors to be tempted by it and want to take possession of it.

Listening to the words of these two overseas Holy Emperors, the surrounding Terran Saint Emperor powerhouses belonging to the Tian Yuan Continent all looked at the two of them with idiot eyes, and one of the kind-hearted Saint Emperors came to the two of them and said in a low voice: "Two brothers, I advise you not to fight the idea of Flame City, and don't even look at it too much, otherwise, I guarantee that you will regret it, because this is something that the Ten Guardian Families dare not move." ”

Hearing this, the necks of the two overseas Holy Emperors suddenly shrank, and they quickly looked away and gathered their thoughts, even the rest of the Terran Holy Emperors from overseas did the same. Something that even the Ten Guardian Families didn't dare to touch, how could they covet it.

At this moment, the pressure between heaven and earth suddenly rose, and immediately a deafening roar was heard, and a huge lightning bolt with a thickness of half a meter slashed down from the whirlpool, and the intense light illuminated the heaven and earth, bringing a moment of snow white, draped on the mountain range below at an incredibly fast speed.
