"Destroy the Heaven Demon Heart, how is this possible?" Nie Tian frowned, his face looking very ugly.
Although the demonic energy in the canyon lurked very deep, and the aura was somewhat different from the Heaven-Destroying Demonic Aura he had felt before, the deeper demonic aura would not change.
This canyon is indeed filled with heaven-slaying demonic energy!
But this was so strange that Nie Tian couldn't figure it out.
"Did the Underworld Emperor ever appear here?" Nie Tian speculated in his mind, but felt it was impossible.
Even if the Hades Emperor had been here before, he shouldn't have left behind such terrifying Heaven-Destroying Demonic Qi.
Even if the Hades Emperor became a saint in the realm, his strength should not be so strong.
If the Underworld Emperor is really powerful enough to release such terrifying demonic energy, then it is impossible for the people of Evil Moon Sirius to catch him.
However, if the devilish energy in the canyon was not left by Hades, who would be?
"The previous owner of the Heaven-Slaying Devil's Heart?" At this moment, Nie Tian suddenly thought of something, frowned, and his expression immediately changed.
Things in heaven and earth, such as stars, Yuanshi, and the Heaven-Slaying Devil's Heart, all have more than one owner.
The Hades Emperor is not necessarily the original owner of the Heaven-Slaying Demon Heart. Before him, the Heaven-Slaying Demon Heart may have had other owners.
Then the demonic energy in the canyon may have been left by the previous owner of the Heaven-Slaying Demonic Heart.
However, if this was the case, why did the shadow of the Underworld Emperor appear in Nie Tian's mind when the demonic energy oppressed him?
Everything seemed like a deep mystery, which completely confused Nie Tian.
What puzzled him even more was why the Demonic Qi of Zhutian made him feel something, and even inspired the power of Haotian's Heart.
"Is there any connection between the Heaven-Slaying Devil's Heart and the Haotian's Heart?" Nie Tian frowned and his face couldn't help but change.
But after thinking for a long time, he didn't have any guesses, so he had to give up.
"Let's go." After a while, Nie Tian calmed down and was ready to leave here immediately.
"Nie Tian, look!" At this time, Wen Renxiang came over, holding a strange flower in his hand, and handed it to Nie Tian.
"What is this?" Nie Tian was stunned and was immediately attracted by the strange flower.
The flower was not big, about the size of an adult's fist, but it looked very strange. The black petals exuded an evil aura, and the whole flower looked a bit like a wolf's head.
"What do you think?" Wen Renxiang laughed, looking very happy.
"Werewolf flower!" Nie Tian suddenly thought of something and screamed.
Previously, Wen Renxiang told him that Langye Mountain is rich in a third-level sacred material called Werewolf Flower.
Judging from the appearance of this flower, it must be a werewolf flower.
"Yes." Wen Renxiang nodded heavily, took out a space ring, and said proudly: "There are dozens more plants in the ring."
"Where did you find it?" Nie Tian was stunned and looked confused.
"From those three guys." Wen Renxiang laughed and pointed at the rotten meat not far away.
Nie Tian's eyes flickered and he understood immediately.
It turns out that the werewolf flower was dug out by Wen Renxiang from the bodies of the three men in black.
"Nie Tian, do you know who they are?" At this time, Wen Renxiang looked at Nie Tian and asked with a strange look.
"You know?" Nie Tian was slightly stunned and asked.
"They are from the Seven Wolves Mercenary Group!" Wen Renxiang nodded, looking a little panicked.
"Seven Wolves Mercenary Group!" Nie Tian couldn't help but narrow his eyes when he heard the name.
When he first came to Langye Mountain, he also met three men in black, who had evil thoughts about Ning Ziyu, and then died on Nie Tian.
One of the men in black once threatened Nie Tian, saying that they were members of the Seven Wolves Mercenary Group.
"Is this Seven Wolf mercenary group very strong?" Nie Tian frowned and asked.
"Yes." Wen Renxiang nodded heavily and said, "The Seven Wolf Mercenary Group is one of the two largest mercenary groups in Langye Mountain. I heard that even the people from Xie Yue Tian Lang would not dare to provoke the Seven Wolves at will.
Wolf Mercenary Group."
"Most of those mercenaries are people with cruel personalities and ruthless methods. They are active in Langye Mountain all year round, hunting and killing various holy beasts."
Nie Tian looked at Wen Renxiang, couldn't help but laugh, and said, "If we kill the people from the Seven Wolves Mercenary Group, will there be any trouble?"
"Probably not." Wen Renxiang was a little unsure and said, "The deaths of these three people are their own fault. As long as we don't tell anyone, no one will know how they died."
"Yes." Nie Tian nodded, smiled faintly, left here immediately without stopping.
After four days of life and death struggle, Nie Tian felt that the demonic energy in the surrounding space was still there, but it no longer oppressed him.
His martial body seemed to have adapted to the demonic energy.
Half a day later, Nie Tian and Wen Renxiang arrived at the other end of the canyon and were about to walk out.
"Wait a minute." But at this moment, Nie Tian suddenly stopped and looked at a mountain wall high in the sky.
"Nie Tian, did you find anything?" Wen Renxiang looked at Nie Tian with a puzzled look on his face, wondering what happened to the latter.
"Wait for me." Nie Tian nodded slightly, then stepped on his feet, and his figure rose into the sky and came into the air.
He had a downcast expression and his eyes were a little strange.
He sensed that there was a strange aura in the void, which actually caused the Haotian Heart in his body to sense it.
But the strange thing is that the surrounding area is empty, as if there is nothing.
"What's going on?" Nie Tian looked confused. He took a deep breath, calmed down, and then began to carefully sense the surrounding space.
After a moment, his eyes flickered fiercely, his eyes fixed on a void on the mountain wall, and he murmured: "This is it."
After saying that, a surge of sword intent surged out of his palm and moved toward the shrouded area.
"Boom!" The moment the sword intent fell, the originally empty place seemed to be impacted, and the mountain wall next to it shook.
Immediately, a black vortex in the void gradually became clear.
The black vortex is suspended in the void, like a dark abyss, constantly releasing strong demonic energy and spreading in the void.
"The demonic energy comes from this vortex!" Nie Tian stared at the vortex of demonic energy, his eyes trembling. He felt the unusually strong Zhutian demonic energy. It seemed that there was endless demonic energy in the center of the demonic vortex.
"I know!" At this time, the ghost emperor's voice suddenly sounded, and he screamed, looking very excited, and said: "This is a large array of demonic energy, and this whirlpool is the large array of eyes!"
"Demon Qi Formation?" Nie Tian couldn't help but froze for a moment when he heard the Ghost Emperor's voice, and let out a surprised sound.
"Boom!" At this moment, the whirlpool of demonic energy seemed to have received some kind of induction, and suddenly became violent, and then exploded instantly, turning into waves of terrifying demonic energy, shrouding Nie Tian.
