There was a huge suction force inside the portal, sucking in all the mutant monsters that had retreated.

The four leaders glanced at each other, on the other side of the portal, it must be the lair of these mutant demon beasts, even if the four leaders were all peak-level major cultivators, they did not dare to enter rashly.

The portal quickly sucked all the mutant monsters inside, and after the last mutant monster entered the portal, the portal disappeared.

The Boulder and the Takuto Cactus Gate are of course the two that enter the portal at the beginning.

"What are these two monsters?"

"Their essence seems to be one of them is a person and the other is a stone?"

"I think the black gas emitted by that stone will be the strongest, and these demon beasts seem to be controlled by that stone and that black qi."

"It has to be."

"Is the monster mutation really because of a strange stone?" Wan Shan muttered.

"Did the Ten Thousand Leaders already know?" The other three leaders all frowned.

"Oh no, it was Lin Gang's investigation before, and he found that the mutation of the demon beast was because of a strange stone, but it was only within the Xishan Alliance at that time...... Not many people believe it. Wan Shanyi's tone broke a little as he spoke, because he felt that the Xishan Alliance was too unfair to Lin Gang.

The other three leaders were also angry and lamented after hearing this, saying that Wan Shanyi, the leader, was too irresponsible, and sighed one by one, eager to criticize Wan Shanyi on the spot.

Wan Shan smiled silently and accepted it, thinking that after this battle was over, he must reorganize the Xishan Alliance, and people like Blue Moon would be the first to be killed.

"But what's even more strange is that when these demon beasts saw Lin Gang's burning array, they all knelt down, why did the demon beasts kneel? This seems a little hard to make sense. Chairman Zhengdao said.

Wan Shan shook his head, he didn't know why this was happening.

The leader of the South Island did not know why.

A brief glint of excitement flashed in the eyes of the City Lord of the Northern Ice City: "Do you know the origin of fire? ”

All three leaders shook their heads.

The leader of the South Island even said: "You people in the Northern Ice City who study the ice method, do you also study fire?" ”

The City Lord of the Northern Ice City laughed and continued: "The first City Lord of the Northern Ice City, you may have heard of it to some extent, she was the first person in the Ice Law at that time. But you don't know that her husband was the first person in the fire law at that time. ”

"Then why hasn't the fire method been passed down?" Chairman Dao asked.

A trace of sadness flashed in the eyes of the city lord of the Northern Ice City: "Because, he is dead." If he hadn't died, the first city lord wouldn't have opened up the Arctic City. ”

"I see." The three leaders all nodded, they knew that the independent space where the Arctic Ice City was located must have been opened up by an ancestor who had cultivated to reach the peak, and today they knew that there was such a story behind it.

"Could it be that Lin Gang's flame is the same as that fire method first?" Wan Shan was surprised.

"Of course not, it's even a big difference." The city lord of the Northern Ice City said, "However, there are three points of resemblance. ”

The burning array released by Lin Gang is extremely demonic, three points black, seven points of fire red, and the flame of the first person of the original fire method is three points similar?

"So the flame of the first person in the fire method is all black?" Wan Shanyi asked.

"You're the youngest leader among us, you're right." The City Lord of the Northern Ice City kept nodding: "At that time, his flame was all black, and he was the only one who could crack the ice method of the first City Lord. ”

The other three leaders nodded their heads as well.

Beasts are born with a fear of fire, and what makes mutated monsters fear can only be the origin of fire.

But why ordinary demon beasts don't have fear of the origin of fire is probably because the fear comes from the known.

If an ordinary demon beast was burned by the Fire Origin once, then it would never dare to face the Fire Origin next time.

The four leaders were amazed.

Finally, the chairman of the Dao suddenly asked, "In addition, shouldn't the city lord also explain the matter of the portal?" ”

"What do you mean?" The City Lord of the Northern Ice City looked at him suspiciously.

"The portal is a technology that only you in the Arctic City can master." Chairman Dao's tone suddenly increased.

Wan Shanyi and the leader of the South Island were shocked, what Chairman Dao said made sense, could it be that there is any connection between the Northern Ice City and the mutant demon beasts?

The city lord of the Northern Ice City had a cold face and asked indifferently: "Have you seen the portal of my Northern Ice City, how similar is it to the portal just now?" ”

The three of them recalled for a while, and knew that they were indeed different, and the two portals were different in terms of appearance, temperament, and even the comparison of exercises.

"I'm just mentioning this, not that it has to be related to Arctic City." Chairman Dao smiled, and his tone softened.

The city lord of the Northern Ice City had a cold face, and his expression was still indifferent.

When the four leaders returned to the location of the Burning Array, the Burning Array had burned out, and the three thousand demon beasts were all killed by the escort.

Within a radius of a kilometer, there were all demon beast corpses, horizontal and vertical on the charred black soil.

At this time, the burning array has been burned out, but the residual temperature of the burning array can still be felt in this land, and it may take two or three days to completely dissipate.

Zhang He, Xu Ting, and Yang Xing hurriedly came to the Lord of the Northern Ice City and asked about Lin Gang's situation.

"It's just that the spiritual power is exhausted, and I will wake up in a while." The Arctic City Lord's tone was slightly calmer, at least much more flat than his usual cold tone.

Zhang He and others also breathed a sigh of relief.

The demon beast has retreated, and there are less than a thousand people left in the escort team.

The people brought by the three top forces have also received orders to return, and there is no need for them to come again.

The city lord of the Northern Ice City hugged Lin Gang and was about to leave with the other two leaders, Wan Shan said: "City Lord, do you want to take Lin Gang away?" ”

The city lord of the Northern Ice City said indifferently: "Lin Gong is here with you, is it really safe?" ”

"But after all, he is a member of our West Mountain Alliance." Wan Shanyi insisted.

"Our doctor Bu made a special trip to explain, let me guarantee the safety of Lin Gang!" The city lord of the Northern Ice City said coldly, this is why he immediately went over to save people as soon as he heard that this person was Lin Gang. "Your Xishan Alliance has put Lin Gang in such danger this time, you should be grateful if I didn't trouble you, and you still want me to hand people over to you?"

"But I really need Lin Gang." Wan Shan said urgently: "If there is no Lin Gang, the Xishan Alliance may be difficult to rebuild." ”

"You want to rebuild the West Hills Alliance?" The Northern Ice City Lord stopped, if the West Mountain Alliance was rebuilt, Lin Gang would definitely be able to hold a high position in the West Mountain Alliance.

Wan Shan Yi nodded repeatedly: "Please also rest assured that within the Xishan Alliance, my Wan Shan Yi's strength will not let Lin Gang be in any danger." ”

The Lord of the Northern Ice City turned around and handed Lin Gang to Wan Shanyi: "If Lin Gang is dead, I will defend the city and destroy your Xishan Alliance!" ”。

What the city lord of the Northern Ice City said was not a lie, he and Wan Shan Yi fighting alone might be a five-five situation, but if the West Mountain Alliance was to be destroyed to the point that Wan Shan was the only one left, a peak-level great cultivator could really do it.

Wan Shanyi took over Lin Gang, as if he had received a treasure of the town faction, and watched the three peak-level cultivators leave, Wan Shanyi bowed deeply.
