"Boom!" The underground space is like ten thousand beasts galloping, exuding a monstrous and terrifying aura, clanging sounds, pieces of crystals are constantly colliding inside, turning into powder, only a small part is taken out, and occasionally half of the pieces are washed out of the thunder cave.

Boom!

Just as I was trying to get a few pieces of blue crystals, suddenly a huge blue crystal blocked the exit, and a huge vibration threw me high and fell on the crystal with a "plop".

"Grass!" I couldn't help but be shocked, it was so sudden that I was caught off guard.

This crystal is 100 meters huge, completely blocking the exit.

"Ka Ka ......" The huge blue crystal suddenly appeared one after another cracks, and it was on the verge of shattering.

"Your uncle!" I thought the crystal would hold for a while, but as soon as I fell on it, it made a cracking sound, as if I had smashed it.

"Bet on him!" My eyes lit up, and with a twist of my hand, a small yin and yang door appeared, rapidly becoming larger, suspended at the exit, facing the crystal, and I myself was holding a colorful halberd, "bang", smashed open the stone wall, quickly dodged a distance, and drilled into the purple pupil space.

As soon as "Boom" entered, I felt that the nearby ground was shaking, and I almost fell and squatted.

Not far away, a pitch-black portal erupted countless blue crystals, blooming like fireworks, shooting in all directions, and many of them were shooting towards me, more powerful than bullets, and I jumped up and down for a while, so I was not embarrassed.

Then countless wind and thunder poured in, and there were also a lot of inexplicable soul breaths.

"Not good!"

My face changed, these soul breaths have a lot of weird breaths, maybe it was the ghost that made it when the ghost fire was promoted, I quickly closed the small yin and yang door, blocked the influx of wind and thunder energy, and at the same time slammed the surrounding space to stabilize those soul breaths, which was completely relieved.

This black gas was confined to me, black as ink, cold and violent, giving people a feeling of madness.

"This aura is really similar to the ghost that appeared in the sea of knowledge, could it be that when I was refining and absorbing, I was exploited by it?" I was shocked for a while, but how did I think it was impossible, since it was refined, how could this situation still occur?

Maybe it's the risk that comes with the Nether Fire Advancement itself!

I couldn't figure it out, but this black qi was very similar to the ghost aura in the sea of knowledge, and it seemed that something went wrong during refining.

This black gas was compressed by me, constantly changing shapes, and even vague skulls appeared, their faces blurred, constantly struggling violently, and roaring silently.

"What is this?" My expression was solemn, this was only a small amount of black energy in it, which was insignificant compared to the entire underground space, but it could initially generate consciousness, if all the black energy in the space was condensed together, it would be unimaginable.

This black energy is completely different from the evil energy I have encountered before, there is no evil aura, but it is not a good thing at first glance.

"Does it have something to do with the Netherworld? But what is that? I frowned, and the words of the black ghost in the sea came back to me.

"The underworld is here, the world is in chaos! This is easy to understand, that is, the appearance of the netherworld, the world is in chaos! I muttered, "But what does it mean that the evil spirit on the path of yin and yang is broken?" ”

"Does it mean that my path to the promotion of cultivating the Yin and Yang Technique was blocked by evil spirits, or is it something else?" I felt a pain in my head, and I couldn't figure it out.

"No matter!" I then had a smile on my face, "If it weren't for the ghost's appearance, my soul flame wouldn't have mutated, and it would have merged with the chaotic energy to form a new flame!" Haha......"

I laughed excitedly, and then activated the Seven-Colored Chaos Flame with a "boom", but what made me frown a little was that the current flame was not colorful, but white with a little bit of color, and it was not as bright as before.

"Alas! It seems that it may be limited by my strength, or that color is the limit burst when it is fused, but the temperature has increased by almost ten times, and it can completely melt those meteorite stones! ”

Then I unleashed the Hybrid Burial Fire, a strange flame that gave a chilly feeling, and in the area it covered, all matter was frozen and then turned into ashes, and this strange sight made me stunned for a while.

Whether this is burned to ashes or frozen to ashes is simply speechless, but this flame really has no temperature at all.

"I don't understand!" I shook my head, a hint of curiosity to test its power.

My body was wrapped in black flames, and the space around me made a "click" sound, and I was like a demon god in the dark, exuding a cold and violent aura, and I jumped out of another small yin and yang gate and came to the stone wall.

"Click......"

As soon as he came out, there was a dense cracking sound of the surrounding mountain wall, and then the "......" was quickly burned out of a round hole, and a layer of white ash was spread under the body, and the round hole continued to spread.

"So powerful?" I was taken aback, and hurriedly cast my yin and yang to escape and rush in the direction of the thunder cave.

But what surprised me was that along the way, I left behind a round tunnel, which instantly burned the earth and rocks in front of me to ashes.

Coming out of the place where the colorful halberd broke, my eyes widened, and the original vent became larger, and more wind and thunder rushed up like a waterfall, erupting outward.

And what I didn't know was that when the entrance of the passage was stopped by that piece of energy stone, the Thunder Cave suddenly stopped the eruption of energy, which made the top level of the Dream Pavilion suspicious, this is something that has not happened in hundreds of years, they immediately sent people down to investigate, and all kinds of protection preparations are very thorough.

However, as soon as the investigators entered, the energy limit of the Thunder Cave exploded, and the people located in the Thunder Cave were directly smashed into pieces, and even the people near the Thunder Cave were affected, and the entire small hill was completely wrapped in thunder and lightning.

The defensive formation set up was also shattered under the impact of wind and thunder energy, and finally exploded completely.

But fortunately, only the people who investigated were killed, and the others were only caught off guard and affected, and the injuries were not large.

The sudden change surprised the top management of the Dream Pavilion, I don't know what happened? Why did the energy become so violent, more than ten times stronger than before!

But then something even more suspicious happened.

The eruption of the wind and thunder later brought some black crystals, these crystals emitted a cold air, the feeling is very ordinary, you can touch it with your hands, but it can make people freeze immediately, and kill directly, instantly turning five or six people into a pile of white ash, so frightened that other people who are ready to contact almost pee their pants.

There are electric arcs and wind blades in the black crystals, which seem to be frozen inside, which is very strange.

This terrifying and weird black crystal made the top management of the Dream Pavilion surprised and delighted, and they were so surprised that they didn't know what happened in the Thunder Cave, and they were happy that this crystal was a heavy treasure at a glance, and its value was extraordinary.
