A black flame, in the air above the head seems to condense out of thin air, quickly and continuously thickening and thickening, only a few dozen seconds later, the black flame actually densely covered a large piece of the sky, so that the space has changed color, the sudden change of the sky, so that the spirit insects, birds and beasts in the mountains and forests can not help but suddenly wail and scream, a few timid people even overflowed with excrement, and they all fluttered and fled in all directions-

Although this place is by no means comparable to the Seven Rivers Valley Plain in the center of the earth, high-level spirit birds and spirit beasts are all over the four fields, but there are definitely not a few ordinary spirit insects, birds and beasts that are generally cultivated here. The astonishment of this celestial phenomenon actually made them flee in panic, which shows how rapid and terrifying this shocking change is.

In a row of houses behind the big playground, in a relatively spacious room, Cao Yu, who had been recuperating for seven days, had almost completely recovered, and he taught the students the method of large space, not every time he consumed his physical strength and even destroyed his cultivation, but he found that this group of students generally had special talents and super strong cultivation, so he decided to sacrifice part of his skills and pass on the karma for them. He was lying down at this time, of course, he could see the sudden changes in the sky not far from the window, and he couldn't help but sit up abruptly and look up at the outside-

As if a storm was coming, a large area of the sky outside was already gloomy, and a large area of black flames, like a thick black blanket, was overcast over the sky not far away.

What's going on? Is there a heresy going on there?

As a Blue Eagle Warrior in the Xuandan Realm, of course he understood that this shocking change in the celestial phenomena was definitely not caused by the force of nature, but must have been caused by man-made, could it be that someone was cultivating there and was about to mutate and advance, so that the celestial phenomena would also change with it?

However, no matter how you think about it, it is also unlikely, only the instructors and students of the cultivation class can enter this large playground, and the soldiers of the Rainbow Muddy Sect are stationed outside to stand guard, and no outsiders can approach them. Among the instructors, he is the chief instructor, and his cultivation is the highest, but he is only in the Xuandan realm, the Blue Eagle Warrior, and the other instructors are still under him; among the students, there are only three or four Dan Realm Red Eagle Warriors, who are already the highest in cultivation, and the others are just getting started or have just started, even if a student in the Dan realm cultivates there and breaks through the level to advance, if he wants to enter the Xuandan realm, he is still at the level of a mere fighter, and the promotion should never cause such a "grand" effect, or even a little "terrifying" scene?!

Odd!

He felt that his body was almost fine, so he decided to go there and see for himself and find out what was going on, otherwise his curiosity would be absolutely difficult to let go. And at the same time, it is also for the safety of the Hongni Sect - in this world of reckless deception and cannibalism for the sake of cultivation, for personal gain, and for profit, it is entirely possible that there are one or two bad intentions lurking there, and even hostile elements!

He gently descended from the ground, pushed the door open, and walked slowly in that direction.

In the woods, the whirlpool on Tie Meng's body is completely in a state of uncontrolled random violent rotation, and Tie Meng, who has already settled, can only sit quietly and control his mental power, in the depths of his spiritual thoughts, he also knows that he is about to break through the level, and in this case, he can only ensure his own stability, in order to meet the upcoming mutation. He had no control over what was happening outside of his body.

"Whew-"

The whirlpool that swirled violently swept high, and instantly connected with the black flame in the sky, and the black flame also spun with it, and in just a few seconds, it was sucked into the whirlpool—

"Whew-"

The whirlpool disappeared in an instant, turning into a ball of golden stars, and after the golden spirit flickered for four or five seconds, it all entered Tie Meng's body at once!

——A large cloud of dark matter and dark energy was sucked from the space, wrapped in the black flame, followed by the golden star, and sucked into the four meridians and two veins of Tie Meng!

"Whew-"

Tie Meng's body suddenly became golden and agitated, the four meridians and two veins operated violently, and the black flames absorbed into his body turned into pieces of black light, whistling outward, and his body suddenly swelled, and even the space was so compressed that the space was trembling slightly like waves! Only a dozen seconds later, the golden light suddenly radiated out of his body, and a piece of golden light burst out in all directions, turning into a golden cloud of smoke, and the black light turned into a black cloud and flew up to the sky, and Tie Meng's body quickly recovered its original state in the center of the violent change!

- Everything is gone!

Tie Meng opened his eyes!

Mutation promotion success!

Tie Meng is no longer a Red Eagle Warrior in the Dan Realm, he is now - Xuandan Realm, Blue Eagle Warrior!

On the surface, his current cultivation is comparable to that of his instructor Cao Yu, both of whom are in the Xuandan realm, and they are both Blue Eagle fighters, but in fact, his cultivation is not known to be many times higher than Cao Yu.

"Rustle—"

In the woods, outside the "tree array", there was the sound of footsteps.

It must be that the "action" of breaking through the level just now is too big, and there are too many appearance visions, which attracted which person came to watch. It seems that I chose to cultivate here too little consideration, and it should be safest to return to my cave on the cliff wall, and I am indeed a little reckless. However, this breakthrough was completely sudden, without any warning in advance, and he was slightly caught off guard.

Fortunately, he had completed the mutation and successfully broken the level, and it was still too late to leave here immediately, so Tie Meng quickly stood up, drilled out of the "tree array" from the other direction in a few steps, and left here almost trotting at the fastest speed.

Almost at the same time, Cao Yu walked in from another direction, and a figure flashed away from the other direction, although he couldn't see who it was, but the unusually striking red hair still fluttered in the air like a ball of coals, so that people could see it clearly.

"Tie Meng?!"

Cao Yu couldn't help but secretly exclaimed in his heart.

If you look closely, there is no trace of it.

While slowly walking back, Cao Yu secretly thought: Although Tie Meng has the highest cultivation among these students, he is only a Dan Realm Red Eagle Warrior, and there are several cultivators of the same level as him, could it be that he has broken through the level and advanced? Just because he has cultivated the Great Space Technique in these seven days? In just seven days, and this Technique is very common, it is almost impossible to advance because of cultivating it! What's more, even if it is a breakthrough and promotion, from the Dan Realm to the Xuandan Realm, it is all within the range of the fighters, and the overall cultivation is still extremely low, and it should definitely not create such an "effect"?!

It's incomprehensible, incredible!

It seems that this Tie Meng is by no means simple, before he came to the Red Muddy Sect, especially in the Black Soul Valley in the center of the earth, he must have had an extraordinary experience and experienced extraordinary cultivation, and his inner cultivation level is by no means as simple as the Red Eagle Warrior of the Dan Realm on the surface - it is now possible that he is as simple as the Blue Eagle Warrior of the Xuandan Realm!

What a Tie Meng, you are really extraordinary, in the future, we must focus on cultivating you and "take care" of you!
