Time was fleeting in cultivation, and when Nanchen opened his eyes again, the sky outside had completely darkened, and the sky that was still clear during the day had been covered by dark clouds from nowhere, and the wind blew down from the dark clouds, and the waves of trees in the mountains and forests were rattling.

Dark clouds covered with dark clouds, and a low thunderclap slowly came out of them, and in the face of the majesty of heaven and earth, the entire mountain range seemed to fall into silence.

"Sting~"

A bolt of lightning tore through the thunderclouds and appeared, and the dazzling light instantly illuminated the mountains as bright as day.

The thunder light reflected on Nan Chen's slightly excited face, and Nan Chen cautiously observed the entrance of the cave for a while before returning to the cave again, and went to the wooden box containing the wind thunder stone with some excitement.

"God help me, I was worried that the movement would be too big to attract other demonic beasts, but I didn't expect this thunder to come so timely!"

Nanchen raised his head slightly to look at the bursts of light at the entrance of the cave, flipped his palm, and took out a stone surrounded by silver lightning.

As soon as the wind thunder stone came out, it seemed to echo the thunder outside, and it instantly became violent, and a tingling feeling spread to Nan Chen.

"Although the power of wind and thunder contained in the Wind Thunder Stone is not as domineering as in nature, it is not so easy to absorb, Chaos Seed, Devouring Battle Technique, it depends on you!"

Holding the Wind Thunder Stone tightly in his palm, Nan Chen exhaled a long breath, his palm trembled slightly, feeling the majestic power contained in it, Nan Chen's state of mind was obviously not as peaceful as it appeared to be.

"Come on! Devour it for me! ”

With Nan Chen's low roar, the black whirlpool in the palm of his hand resurfaced, and at the same time, the originally honest wind and thunder stone suddenly rioted, and instantly shot into the air, with a deafening thunder outside the cave, the wind and thunder stone suspended in mid-air suddenly shattered, and a trace of silver thunder arc was like a beast that escaped from its cage, scurrying around in the cave.

The speed of these thunder arcs was extremely fast, bringing up light and shadow in the air, and for a while, Nan Chen's eyes were suddenly dazzled.

Although Nanchen was ready, at the moment when those thunder arcs burst out, there were still some surprises, but in addition to being surprised, Nanchen immediately accelerated the operation of the Devouring Battle Technique, the chaos seed at the dantian trembled slightly, and the black vortex in Nanchen's palm became more profound, and a more huge suction force was generated from it, and the thunder arc that was originally scurrying in the cave was gradually pulled by the suction in the whirlpool, and began to move slowly towards the whirlpool.

I don't know how long it took, when the first ray of thunder arc finally entered the whirlpool completely, Nan Chen's body stiffened violently, his face turned purple red, and a trace of silver arc flashed between his dark eyes.

The hands quickly flipped over, the devouring battle trick ran wildly, Nan Chen's mind entered his body like lightning, and as his mind entered the body, the silver douzhi cyclone in his body also spun wildly, only to see that after the trace of thunder arc entered Nan Chen's body, it was like a cat that met a mouse, running straight towards the chaos seed in the center of the cyclone.

Watching this scene with his heart, Nan Chen manipulated the fighting qi in the cyclone to intercept the thunder arc, but found that his fighting qi was vulnerable in front of the thunder arc, and it was scattered in the blink of an eye.

Seeing this, a trace of helplessness rose in Nanchen's heart, but he could only watch as the thunder arc slammed into the chaos species.

Nan Chen, who had palpitations, watched as the thunder arc hit the chaos species, the chaos species did not move, but the thunder arc instantly turned into more small thunder arcs, flickering on the chaos species for a moment, and then quietly blended into it.

Seeing this scene, Nan Chen's heart was slightly lowered, his mind withdrew from his body, and a black vortex appeared again in his palm, and he began to pull other thunder arcs in.

The thunder arc entered Nanchen's body, and the powerful power of wind and thunder circulated in Nanchen's body, numbing and painful at the same time, it was also imperceptibly improving Nanchen's physique.

Feeling this, even if it hurts, Nanchen can only grit his teeth and endure it, so he doesn't know how long it will last, when the last wisp of wind and thunder power in the air enters Nan Chen's body, I saw that the originally quite quiet Douzhi cyclone, with the injection of this last wisp of wind and thunder power, suddenly rioted, like a drop of water dripping into a pot of hot oil, boiling violently, and at the same time a fierce suction force surged out from it.

With the changes in the body, the cave where Nanchen was located also began to set off an invisible storm, and the energy of heaven and earth began to converge, under the pull of the cyclone, a large amount of energy began to enter Nanchen's body uncontrollably, and a huge amount of energy converged around Nanchen's body, and finally formed an energy light curtain, which was quite dazzling.

And in Nanchen's body, above the chaos species in the center of the cyclone, a dark silver thunder snake with the thickness of a thumb hovered over it, and a pair of dark silver pupils with a little dark black light looked quite indifferent.

"This chaos seed is really magical, it actually fuses the power of wind and thunder contained in the wind and thunder stone, and it seems to be mixed with other powers, so that it forms a snake shape, it is like a strange thunder like a different fire, but it is just a weakened version."

Looking at the thunder snake in the cyclone, Nan Chen didn't have time to think about it, at this time the energy in his body was close to saturation, but the fighting cyclone was still absorbing the power of the outside world, at this time Nan Chen had already felt something, his meridians had begun to swell because of the overloaded energy, if it continued, I am afraid there would be a danger of bursting.

"God, don't play with me like this, if you die like this, it's too embarrassing!"

Seeing that the speed of absorbing energy did not decrease in the slightest, even if Nanchen had already given up the operation exercise. At this moment, Nanchen shouted a little like crying.
