The reason why this low-level magic crystal rough stone exploded was because the mana of the Heavenly Demon Thunder Wolf was too pure.

It must be known that the miniature formations engraved on different grades of magic crystal rough stones are naturally different. The more high-level magic crystals, the more complex the magic circle that needs to be imprinted. The miniature formation above the low-level magic crystal could not store too pure mana at all, which was why the low-level magic crystal rough stone just now would burst.

Although the Heavenly Demon Thunder Wolf had never seen a mid-level magic crystal, he still understood this simple truth.

Just as the Heavenly Demon Thunder Wolf was contemplating and pondering, suddenly, a faint killing intent came from hundreds of feet away, making him feel vigilant in his heart.

The faint sound of percussion, the earth was trembling slightly, and the weak and imperceptible force was transmitted along the earth to all sides, like sparkling water waves, the soft voice, but the cold killing machine had already been buried under the ground, unfathomable.

If it weren't for the fact that the Heavenly Demon Thunder Wolf was naturally extremely sensitive to killing machines, I am afraid that he would not be able to detect the killing machines coming from under the ground.

At the same time, Xichen, who was munching on fat chickens in the private room, suddenly stopped moving, and his ears were erected, as if he was listening to something.

The Falling Heavenly Destiny and the big red robe on the side did not react, still looking at the pile of magic weapons in a daze.

"Oops!" Xichen suddenly exclaimed, as if something terrible had happened.

"What's wrong?" Falling Heaven and Da Hong Pao jumped up at the same time, not knowing what was going on, and their faces were full of doubt.

Xichen said with some panic: "Underground, it feels terrible, it seems like I'm going to kill someone." ”

Falling Heavenly Destiny and Da Hong Pao couldn't understand what Xichen was saying, and they were confused.

This kind of murderous feeling was like the sense of urgency before the fall of the fox clan, but the mana of cherishing dust at that time was low, and it was far less intense than it is now.

As time passed, the heavy killing machine oppressed, and the Falling Heavenly Destiny and the big red robe finally noticed something unusual, and they couldn't help but feel urgent in their hearts, and their heartbeats accelerated inexplicably.

"Big brother, big brother......" Xichen suddenly screamed in panic, his body shook, and he disappeared suddenly, and the big fat chicken was also thrown aside by her.

"Killer!" Falling Heaven and Da Hong Pao glanced at each other, finally understanding why they felt this way. Then, the two of them shook their bodies and came to the side of the Heavenly Demon Thunder Wolf, but they saw Xichen holding his arm tightly, and his petite body trembled slightly.

"Big brother, don't leave Xichen alone, Xichen is afraid!" Xichen said vigorously, staying by the side of the Heavenly Demon Thunder Wolf made her feel at ease.

"Hmm!" the Heavenly Demon Thunder Wolf replied softly, and then said to the Fallen Heavenly Destiny and the big red robe, "Second, third, take care of Xichen!" As he spoke, the Heavenly Demon Thunder Wolf had a little luck and sent Xichen to the two of them, and then jumped into the air, standing in the air, his breath rose sharply, and the surrounding wind gusted, and the space suddenly trembled.

"What's going on?" Sensing the movement of the space, many people on the street came out to take a look. A moment later, a dense crowd of figures appeared on the street, and for a moment it was extremely noisy, and the sharp murderous intent disappeared without a trace.

"Huh?" the Heavenly Demon Thunder Wolf snorted lightly, a look of doubt on his face. Although his consciousness searched repeatedly within a radius of ten miles, he could not find the source of the killing machine, as if he had disappeared out of thin air, and there was no trace.

After searching for a while, the Heavenly Demon Thunder Wolf couldn't find the killing force after all, so he had to regain his momentum and slowly land.

The surrounding crowd saw that there was no drama to watch, and they immediately shouted non-stop, and many people who had been interrupted were even more scolding. The audience gathered quickly and dissipated quickly, and in the blink of an eye, the whole street was empty again, and there was no longer half a figure.

"Boss, how's it going?" asked Falling Heaven with a nervous expression, the things in the Ascension Domain were always beyond his imagination.

"A clever killer!" The Heavenly Demon Thunder Wolf said, and then secretly urged the Reverse Heaven Thunder Decisive to open the Heavenly Demon Phantom Pupil, and under the strafing of the pale green pupils, the Heavenly Demon Thunder Wolf quickly targeted an old man holding a bamboo cane.

The old man's aura was extremely flat, no different from ordinary people. The old man sat at the stone table, drinking tea leisurely, blindfolded with a black cloth, and no expression could be seen on his old face, as if he had been sitting there and had not left for a long time.

There was not the slightest flaw, nor the slightest murderous overflow, as if it was integrated with the surrounding space, and the old man, who was very easy to ignore, was unexpectedly locked by the Heavenly Demon Thunder Wolf, not because of anything else, but because it was too bland, and the reaction of the surrounding crowd was extremely different.

The Heavenly Demon Thunder Wolf has always believed in his instincts, but he suddenly had words in his mouth, and the wind vitality in his body surged, and then he flicked his fingers and shouted: "Wind spirit, disease!"

A cold light with a tail finger shot out, instantly spanning a hundred zhang and hitting the old man's eyebrows.

"The law of space!" There was a trace of surprise on the old man's withered face, his body did not move, the bamboo cane moved slightly, only a snort was heard, and the wind spirit hit the bamboo cane, causing a wave in the surrounding space, but the old man did not have anything to do, and the bamboo cane in his hand did not leave any traces of being beaten.

The Heavenly Demon Thunder Wolf couldn't help but show a look of emotion, this wind spirit, but he drove fifty percent of the Wind Yuan Gong, and then formed it with the help of the law of space, the power is not small, and the ordinary immortal master can't block it lightly. However, the seemingly ordinary old man was not only able to block it calmly, but also seemed to be at ease, as if every movement of the Heavenly Demon Thunder Wolf had been completely controlled by him.

"What a Dao boy, his ability is not bad. Such a pure wind vitality is really rare in heaven and earth, but it is a pity that it is not needed by this master!" The old man's voice reached the ears of the heavenly demon thunder wolf, without any feeling, it was extremely bland, "Take the three moves of this master, and let you live!"

As he spoke, the old man lifted the bamboo cane, and then lightly slammed it to the ground, and in an instant, the undercurrent surged, and a powerful earth vitality turned into a yellow mang, and broke through the earth with a whoosh, directly attacking the heavenly demon thunder wolf.

"Immortal Master!" The Heavenly Demon Thunder Wolf was shocked, mobilizing the Heaven and Earth Yuan Qi so without a trace, this old man was only afraid that he was not an ordinary Immortal Transformation Master.

Immediately, the figure of the Heavenly Demon Thunder Wolf flashed, and he fled into the air, appearing at a height of a hundred zhang in an instant, dodging a blow from Huang Mang, and then another wind and spirit in his hand, directly attacking the old man, and making a chilling whistling sound along the way, which was more powerful than before.

The old man still said with a blank face: "Arrogant boy, if you have time to make a move on this master, let's take care of yourself first!"

Hearing this, the Heavenly Demon Thunder Wolf couldn't help but be shocked, the Huang Mang, who had already been dodged by him, suddenly folded halfway, turned around and continued to attack the Heavenly Demon Thunder Wolf, so fast that people couldn't react at all.
