The corners of Yin Dong's mouth twitched, this really has nothing to do with the green smoke coming from the ancestral tomb, it was the master who changed his life against the sky, and he had the opportunity to create after being reborn.

Jiang Laozu looked at Yin Dong with complicated eyes, feeling that he had not yet reined in his momentum, and what flashed in his mind was still Yin Dong's previous appearance of thunder arc electric light all over his body, and his mood was extremely complicated.

This kid is not afraid of the Thunder Tribulation, which is equivalent to getting the pass to the Holy Realm in advance, as long as the resources are sufficient, he can directly pile up the Holy Realm, and there is no need to worry about falling under the Thunder Tribulation of the Holy Realm.

The vast majority of the other half-uncle saint ancestors will die under the thunder tribulation, and only a few can survive the thunder tribulation. If you let them know that this kid can devour the Thunder Tribulation, and his eyes will be green with jealousy, right?

No!

Wrong!

Yin Dong can devour the Thunder Tribulation, this ability is too rebellious, those Shou Yuan will not be able to survive the Thunder Tribulation Ancestor, once he knows that he has this ability, he will definitely arrest him to help him survive the Tribulation, even if the Thunder Tribulation Cloud is swallowed, it is worth it to become a Void Saint!

"Today's matter must be kept secret, and not a word of tone must be revealed, otherwise, Yin Dong's life will not be guaranteed!"

Suddenly, Jiang Laozu's solemn voice sounded, which made everyone stunned, and then they all firmly said that they would keep it secret and would not leak it.

The people in the military were simply afraid that Yin Dong was in danger, but the ancestors thought that Yin Dong's ability could allow them to have one more hole card to save their lives when they broke through the Holy Realm.

WhewW......

The yin wind blowing from the depths of the locust forest rolled up a black mist, as if wrapped in countless ghosts, surging like a tide, and the decaying ancient trees and dead leaves in the forest rose with it, and there was an ominous breath in the air.

"Is this the ominous black fog of the border?" Yin Dong's perception diffused, and the situation in the depths of the locust forest was mapped into his mind, making him speechless.

The hills where the locust forest took root, like a black python emitting black gas, stretched along the river bank until it reached the edge of a swamp with black gas. The closer you get to the swamp, the chill in the yin wind becomes more and more bitingly cold, penetrating deep into the blood marrow.

The strength of the ancestors was suppressed even more, and their qi and blood seemed to be frozen. If it weren't for the warriors carrying them on their backs, this stretch of the road alone would have been enough to stop them.

The state of the warriors is not very good, even if the power of the rules of the border wasteland does not suppress their strength, but, at present, they are strong in speed and attack power, and the defense of flesh and blood is not as good as that of the ancestors.

The yin wind swept the black mist in the depths of the locust forest, and the black gas of the forest eroded the trees, as well as countless rotten white bones in the forest, blowing on people, in addition to the chill of the blood marrow, there was also a strange corrosive power, which made people's hearts palpitate.

Yin Dong couldn't help frowning, the situation in the locust forest was getting more and more weird, it was inexplicably uneasy, it was better to go out quickly. Anyway, it's a long way from the river where the silver carp monster crossed.

"Let's go, go sit ......"

Before the last word "boat" was finished, the yin wind in the depths of the locust forest swept up the black mist, and it swept wildly, enveloping a small half of the people, and then, like countless ghosts, dragged these people shrouded in the black mist, retreating towards the depths of the forest.

"You all exit the locust forest, I'll chase after you!"

Yin Dong's eyes burst with light, and his body swept in, rushing towards the depths of the locust forest. His dragon technique and teleportation have become extremely fast. Rao was like this, he didn't catch up with the person who was swept away by the black mist, and when he crossed the locust forest and saw the endless black mist swamp in front of him, he suddenly gasped.

In the swamp filled with black mist, the outline of a city suddenly appeared!

It was a ruined ancient city, the city was a hundred zhang high, and the dilapidated city gate was also thirty zhang, as if it was painted with black mud, and the city walls were all black, whether it was a high battlement or a collapsed city wall, it was all black, there was a yin qi around, the yin wind shouted, countless ghosts floated in the city, dancing in the yin wind, or dispersed, and manifested in another place in the next moment.

"Frontier Ancient City!"

Looking at the dark ancient city in the swamp, Yin Dong remembered the city mentioned by the Wu of the Yan tribe, the city that disappeared, was once the core of the border wilderness, and the strong men who ruled the entire border wilderness lived in the city, and disappeared overnight with this ancient city.

According to the records of the Wu lineage, it is said that the disappearance of the ancient city of the border wilderness was due to the ominous black fog, and the people in the city were also imprisoned in the city by the ominous black fog and could not leave. If you want to save the people of the border city, you need to destroy the source of the black fog.

Yin Dong didn't want to destroy the source of the black fog, take unnecessary risks, and didn't want to rescue the people of the ancient city in the border wilderness, so as not to cause trouble. However, the soldiers who are now swept away by the black fog are obviously swept into the border desert ancient city, and he can be saved if he is not saved now.

"What a wicked city!"

As for the source of the black fog, Yin Dong didn't know where to look for it, so he adopted a simple and crude stupid method to enter the ancient city to find someone. Just let him find the missing warrior and rush out of the city.

WhewW......

Yin Dong walked in from the open and dilapidated city gate, and the howling yin wind blew so that his eyes were almost unable to open, and the cold to the bones was like a knife, piercing into his body, and even the blood marrow was about to freeze and crack.

"Sizzle...... It's so cold! The wind is so weird. ”

Yin Dong muttered, and the dragon yuan on his body came out of his body, and a scorching breath erupted, dispelling the chill that swept in. His body was like a walking furnace in the dark streets of the ancient city, shining in the chill that filled the world.

The howling yin wind, blowing on Yin Dong's body, all disappeared without a trace, and it could no longer have any impact on him.

Yin Dong strolled through this empty and uninhabited street, looking at the white bones that could be seen everywhere on the street, there were human races, there were birds, there were beasts, there were poisonous insects, and some white bones that he couldn't identify the race.

Countless white bones, as if extending from the end of every street, spread all over the city, Yin Dong will step on a broken bone from time to time, and the sound of clicking is endless, echoing in the silent street.

This dilapidated ancient city, the layout is similar to those ancient cities in Blue Star, but it is more majestic and magnificent, more huge, the palaces and pavilions in the city are innumerable, all of them have collapsed, only the square in the middle of the city stands a tall tower, the whole body is dark, the spire is submerged in the thick black fog, as if piercing the depths of the sky.

Yin Dong saw the tower from a distance, and inexplicably felt a sense of palpitation, and couldn't help but pause.

There are more white bones near the tower, piled up like a mountain, lining the tower, which is completely black, like a giant beast lying on the ground, and the door of the tower is the mouth of the giant beast with a bloody basin.

"Is this the Evil Tower of the Ancient City of the Border Wilderness?" Yin Dong muttered.
