The inside of the 10,000-year-old iceberg is hollow.

I saw a flame that seemed to be alive floating in the air, bursting out with extremely amazing terrifying heat, and what was even more amazing was that around this spiritual flame, hundreds of ice crystal flowers were clustered, flashing with brilliant glow, connected together, as if they were resisting the terrifying heat together, and it was like collectively guarding something.

Originally, with the terrifying heat burst out of that spiritual flame, it was enough to completely melt this 10,000-year-old iceberg, and the ice crystal flowers were also obviously different from ordinary ice crystal flowers, looking extremely high-grade, any one of them could completely freeze the nearby space, but at this moment, there was an incomparably delicate balance between the two.

The two energies of extreme cold and extreme heat tumbled endlessly, flowing rapidly, forming a strange force that constantly permeated the internal space.

"What a rich force of fire, what the hell is that flame?!" Zhang Yu's eyes flickered, and he was shocked.

Those ice crystal flowers that seem to be of extremely high quality are still secondary, the key is the force of fire, he who cultivates the Demon Dragon Yan Technique, his perception of the force of fire is extremely sensitive, and he can clearly perceive that the force of fire that permeates the surroundings is extremely rich, even if he refines a large amount of fire spirit grass, it cannot be compared to this place.

It is no exaggeration to say that this is an excellent place to cultivate!

"Origin Spiritual Fire?!" Zhang Yu's eyes suddenly lit up, and his face showed ecstasy.

Through the optical brain query, coupled with his authority in the Cosmic Martial Arts Alliance, Zhang Yu finally knew what that spiritual flame was, if he didn't guess wrong, it was probably an origin spiritual fire.

According to the description given by the Cosmic Warrior Alliance, the Origin Spiritual Fire is extremely rare, and it can only be conceived in places where the force of fire is extremely strong and after certain harsh conditions are met.

Each Origin Spiritual Fire has its own spirituality, and it is a cultivation treasure coveted by a martial artist with the Force Force attribute of Fire, after absorbing and fusing it, it can greatly improve the strength of the martial artist, and there is a certain chance to stimulate a special power attribute, which in turn greatly increases the attack combat effectiveness of the martial artist.

If you want to exchange for an Origin Spiritual Fire, you need at least 10,000 Chaos Coins!

After seeing it clearly, Zhang Yu couldn't help but gasp, now he had an extremely deep understanding of the purchasing power of Chaos Coins, and he knew very well what 10,000 Chaos Coin meant.

It's developed!

Zhang Yu was extremely excited and excited, he didn't expect that by chance, he actually found an origin spiritual fire, originally under the persecution of the Mossa family, he just came to Grosso Devil Star, as unlucky as he was, but now he is a blessing in disguise.

"I didn't expect the Demon Mind Butterfly to have this function, which can help find cultivation treasures!" Zhang Yu smiled excitedly, the place where this Origin Spirit Fire was hiding was extremely hidden, if it weren't for the guidance of the Demon Thought Butterfly, who would have thought that such a rare treasure would be bred in this seemingly ordinary iceberg?!

What made Zhang Yu even happier was that the Demon Butterfly had finally begun to try to communicate with him, even if it was expressed through the Evil Eyeball, but no matter what, it was a good start.

As if sensing Zhang Yu's intrusion, the Origin Spiritual Fire violently swallowed flames, wanting to escape from this place, but under the containment of hundreds of ice crystal flowers around it, it was difficult for it to break this balance for a while, let alone escape from this place.

This is self-bondage!

Originally, that Origin Spiritual Fire deliberately attracted so many high-grade ice crystal flowers, wanting to sharpen himself so that he could improve his strength as soon as possible, but now he was trapped in place and couldn't move.

"Sure enough, there is spirituality!" Seeing this, Zhang Yu couldn't help but chuckle, becoming more and more sure of his guess, this was definitely a ball of origin spiritual fire.

After muttering slightly, Zhang Yu did not rashly break this strange balance, one was to prevent the mass of origin spiritual fire from escaping, and the other was that this place was an excellent cultivation place, Zhang Yu was not in a hurry to absorb and fuse that group of origin spiritual fire.

With an excited smile on his face, Zhang Yu sat directly cross-legged on the ground and cultivated here.

Originally, Zhang Yu also planned to cultivate by refining the exchanged Fire Spirit Grass, but now that he doesn't use it, his cultivation speed here is faster, and he can save time by refining the Fire Spirit Grass.

Demon Dragon Flame Recipe!

Blessed to the soul, in such an excellent cultivation treasure place, Zhang Yu simply comprehended the advanced chapter of the Demon Dragon Yan Jue, before he only cultivated the basic introductory chapter, now that he has basically comprehended and controlled, it is time to comprehend the deeper advanced chapter.

The advanced chapter of the Demon Dragon Flame Recipe is divided into nine levels, also known as the Nine Transformations of the Demon Dragon, each change can change a part of the body, and then burst out with amazing power, when the Demon Dragon Nine Transformations are truly achieved, it is entirely possible to transform into a Demon Dragon, whether it is the realm of strength or the combat power, it is terrifying to the extreme.

"The first change, the magic dragon claw!" Zhang Yu's eyes flickered, and he calmed down.

I saw that as he urged the Demon Dragon Flame Technique, a black dragon soul shadow emerged, and after feeling the extremely rich fire force around him, especially the origin spiritual fire, he suddenly swam happily, and where the figure passed, the nearby rich fire force was swallowed and absorbed by it, and then finally submerged into Zhang Yu's body.

Not only that, in this process, the body of the black dragon soul shadow became clearer and clearer, especially its dragon claw part, as Zhang Yu continued to comprehend the Demon Dragon Claw Technique, it began to gradually mutate, gradually evolving from an ordinary black dragon claw to a demon dragon claw, and then burst out with extremely terrifying magic power.

The spiritual origin spiritual fire felt a great threat, and struggled to break free, trying to escape, but it was useless, now it was not only blocked by the surrounding high-grade ice crystal flowers, but also firmly locked by the black dragon soul shadow.

The spiritual origin spirit fire trembled, and there was an instinctive intuition that once it fled, it was very likely that it would be swallowed up by that black dragon soul shadow in an instant.

For a moment, that group of origin spiritual fire was in a dilemma, and fell into an extremely desperate situation.

Zhang Yu didn't know the situation in the outside world, at this moment he was completely immersed in the comprehension of the Demon Dragon Claw Exercises, the Demon Dragon Yan Jue cultivation exercises were extremely mysterious, thinking that the basic introductory chapter alone made him think a lot of brains, and now the advanced chapter of the Demon Dragon Claw Exercises is even more so.

However, being in such a treasure land of cultivation, Zhang Yu realized that he had twice the result with half the effort, and the originally extremely difficult cultivation method had quietly become simpler, at least it was much easier to comprehend.

Two months later, when Zhang Yu finally succeeded in comprehending the Demon Dragon Claw Technique, he didn't stop at all, and immediately couldn't wait to cultivate, and made up his mind to attack the realm of general-level strength!
