A huge sense of oppression was silently enveloped by the cold aura that was unique to hell. Even Wren, who was surrounded by thunder and lightning, couldn't help but show a trace of solemnity, the fear that invaded the bone marrow still remained in his mind, but unlike before, this time he would not be crushed by this feeling of nothingness again, and the pain brought by the thunder element flowing in the flesh and blood could make Wren stay awake all the time, and his sharper and sharper eyes were locked on the figure in the black flames from afar.

Karthas walked out of the pit step by step, his slow steps looked particularly heavy, as if with each step, the ground would tremble, like the approach of an ancient beast, behind him was a pack of wolves condensed by the flames, the dancing flames burned quietly on the wolves, and a large amount of black smoke rolled towards the sky, like a rising dark cloud, covering the sky and the sun......

Karthas's originally cold and unruly face became particularly hateful in the billowing black smoke and cold flames, and his violently trembling eyes and the green tendons on his temples burst out like angry snakes made him reveal an extremely rare side, hideous and angry, but with inexplicable fear.

[The Sigh of the Immortal Emperor] is a flame from hell, it represents despair and death, when a large amount of Stygian flame burns at the same time, even if it is not directly swallowed by the Stygian flame, within the scope of Karthas's soul power, the heavy breath of hell will gradually erode all the living beings on the ground, making it sink into endless fear, unable to extricate itself, like a withered flower gradually withering......

Even if he has mastered the ability of the Underworld, but Karthas is still not immune to the spiritual erosion of the Underworld, all living beings naturally include himself, driving the Underworld for a long time, not only will consume the soul power sharply, but more importantly, it will slowly corrupt Karthas's will, although his Stygian Flame is as terrible as a nightmare, but it is also an extremely sharp double-edged sword, on the battlefield, the longer the enemy drags on, the more unfavorable it will be to him.

However, at this time, Karthhas had no choice, although he was extremely reluctant to admit it, but he had to face the fact that Wren's sudden leap in strength was almost at the same level as him, so no matter what, he had to squeeze out all the power hidden in his body and give it a go without reservation......

"It's almost close to the limit...... "The pain caused by the crazy flow of thunder elements in his body became clearer and more intense with the passage of time, and Wren's heart was silently anxious, time was also precious to him, there were too many coincidences in this fateful battle, as if the gears of fate had already been doomed......

"I can't go on like this, I have to fight quickly!" Looking solemnly at the black flames burning on the opposite side, the look in Wren's eyes suddenly sank, his legs crossed one after the other and squatted slightly, quickly accumulating strength and then suddenly exerting force, the entire slender figure was once again like a sharp arrow shot out by a crossbow, "whoosh" The ground flew through the air towards Karthas, so fast that there was not even an afterimage of him left in the air, only a fleeting purple arc of electricity and a cloud of dust rolling up after his figure flew.

"Can the speed be improved?!" Karthas looked at the figure that seemed to have disappeared into the air in vain, and the horror in his heart couldn't help but add another point, but in an instant he calmed down, the cold light burst out in his sharp eyes, and the soul power around him was frantically agitated, and the wolves condensed by the Darkness Flame watched vigilantly with scarlet eyes for the faint ripples of streamers in the air, "However, this is now my realm, the realm eroded by hell, you can't defeat me!"

Countless [wolves] quickly surrounded Karthas in the middle, and even the sky was covered with such cunning wolves, their huge and dexterous figures floating in the air like a cloud of condensed smoke, and even the gusts of wind brought by Wren's lightning-fast movements could not blow their forms away.

Wren moved around the wolves at high speed, searching for a breakthrough wrapped in flames, while the outermost wolves were silently prostrate on the ground, their scarlet eyes turning back and forth in the pure black sockets, like a group of beasts waiting for an opportunity, even if each [Dark Wolf] could only capture a little soul power left after Wren moved at high speed, but this group of wolves transformed by the Dark Flame seemed to have the ability to share their sight, and as time slowly passed, Wren's trajectory was gradually exposed to the eyes of the wolves.

It's really weird to say that this group of wolves conjured by fire actually has the vision of creatures, and even the ability to think independently, this group of ethereal wolves is obviously more terrifying and unbelievable than the real wolves, but Wren obviously has not yet noticed this. It wasn't until countless [wolves] were frantically chasing him around that Wren vaguely realized that something was wrong, Karthas couldn't lock on to his figure a moment ago, but this group of [wolves] could follow his trajectory and pounce, at first they could only helplessly pounce on his dissipated afterimage, but soon, the swarming wolves began to keep approaching his body, their speed was far inferior to their own, but with the advantage of numbers, they almost attacked Wren's figure several times from all sides.

"No, it can't be?!!Is that guy already able to capture my form?" The anxiety and horror in Wren's heart were like crazy vines, beginning to entangle his violently beating heart, he had already noticed the [Dark Wolf] snowy and cunning eyes, the scarlet light was as dazzling as spilled blood, "No, it's not like that guy, it's more like this group of wolves......"

"Did you notice?" Karthas's gaze followed the swarming wolves to the flickering figure, and in the face of more and more blockades, Wren's speed was forced to slow, and his figure was completely exposed in a short flicker, "[Wolves] It's not a simple wolf shape conjured up by the flames, in a sense, they can be understood as creatures, creatures living in hell, they have their own five senses and even thoughts, and what's even more terrifying is that they have five senses and the sharing of thoughts, a pair of eyes can't catch you, so what about thousands of pairs of eyes?"

"It's really more difficult to deal with than I imagined!" The figure that was gradually cornered came from a still calm and calm voice, surrounded by flashing thunder and lightning, Wren's face was as indestructible as a rock, he was urging all the soul power left, and at the moment of life and death, he could only make a desperate bet, "Then I will make a final decision......
