Han Feng guessed that the Flame Demon King of Wei Wenguang and the others was also the early stage of the Ten Stars of the Heavenly Order, and their limit was there.

No matter how strong they are, except for Wei Wenguang, the other four are afraid that they will only fall.

In Han Feng's opinion, whether it is the Wind Void or the Demon Water or the current Fire Demon Domain, it is all for the purpose of testing qualifications, a qualification to enter the True Ancient Emperor Secret Realm.

Since it is for detection, there may be dangers, but there will never be excessive casualties.

From Wei Shichen's narration before, Han Feng knew that every time the thirty people who entered the secret realm of the ancient emperor, almost ten fell to the limit, and basically there would be no more casualties.

More casualties were in the real Ancient Emperor Secret Realm.

Every time there were twenty or even more than twenty people entering the True Ancient Emperor Secret Realm, there were four or five people who came out, and the average one per family was already extremely remarkable.

"But...... This time, unlike the previous ones, there was a ghostly storm, a demonic vortex, and the previous fire calamity. The number of people who could truly reach the Ancient Emperor's Secret Realm this time was very likely to be less than twenty. ”

......

Roar!

The Flame Demon King on the other side of Han Feng was immediately furious when he saw that the small human was only thinking about himself and ignoring it.

This Flame Demon King resembles a giant, both in appearance and size, it is extremely similar to a real human, but behind it is four flame wings.

The Flame Demon King's wings flapped, and countless flames fell from the sky like meteorites.

Han Feng's eyes flashed: "Since the Flame Demon Fire Domain has arranged for me to be a Flame Demon King of the mid-level ten-star level of the Heavenly Rank, it seems that I think my strength is relatively strong, but ...... Still underestimate me!!"

"Convergence...... Cangyan Annihilation Slash!!"

A top-grade Heavenly Rank Superb Martial Skill, Han Feng's blow is comparable to the middle and late stages of the ordinary Heavenly Rank Ten Stars, and it is not an exaggeration to say that it is even the peak of the late stage!

The surging flames intercepted and devoured all the meteorite flames, and then turned into a flame giant sword and pierced through the body of the Flame Demon King.

The voice of the Flame Demon King's roar froze, and the huge body suddenly burst open.

"Huh?" Han Feng suddenly exclaimed, because Han Feng was surprised to find that after this Yan Demon King died, a fiery red crystal the size of an adult's fist had fallen.

No, it can't be said to be fiery red, fiery red is just the appearance, but inside the core of the crystal, it is golden yellow.

Picking up this crystal, Han Feng could fully feel the surging fire spiritual power in this crystal nucleus.

"This ...... It's completely fire crystals. If you fall out of the body of the Fire Demon King, then become the Fire Demon Fire Crystal. ”

"Although this fire spirit power is also manic, it is different from the furious fire spirit power in the air of this fire demon fire domain, I can completely put this fire demon fire crystal into the spirit spring to wash it, and then the violent energy will disappear. ”

"Or after refining and devouring, it will enter the spiritual spring to absorb it. ”

The original earth-level fire attribute demon core was absorbed in this way.

Han Feng's eyes lit up: "Could it be that all the Flame Demon Kings have Flame Demon Fire Crystals?" If that's the case, I'm not looking forward to getting out of here right now, anyway, with the Soul Jade Plate, King Guangjun and the others won't think I'm dead." ”

This is the fire crystal that fell after the death of the Yan Demon King, what is the strength of the Yan Demon King? It is a ten-star cultivation of the Heavenly Rank, and the fire crystal that falls from this kind of cultivation may not be able to compare with the spirit fruit of the top-level pure yuan fruit that enhances cultivation, but it can still provide a large amount of fire attribute energy for people to cultivate.

If it was a Heaven-Rank Ten Star, or even the Heaven-Rank Nine-Star Peak, he might not care too much about this Flame Demon Fire Crystal, but Han Feng himself was only a Heaven-Rank Seven Star, so it would be different.

Holding the Flame Demon Fire Crystal in his hand, Han Feng muttered to himself: "Maybe before leaving the Flame Demon Fire Domain, not only Xiao Yan can improve his cultivation, but I will also do the same." ”

......

"Winged Spirit Heavenly Sword!!"

The silver-white energy giant sword and the huge fireball that erupted from the Flame Demon King collided violently.

Powerful energy fluctuations raged out.

One person, one flame demon king, the battle is extremely fierce.

The two fought on par!

But gradually, Wei Wenguang became out of breath, and Wei Wenguang was weaker than a little bit at the energy level after all, and he was already feeling struggling at the moment.

Rumble!

After another attack and collision, Wei Wenguang continued to retreat for nearly a thousand meters: "It is worthy of being a flame demon king comparable to the peak level of the Heavenly Order, it is really powerful." Seeing the way it is now, I have to use that trick. ”

"Winged Spirit Colorful Sacred Rainbow Fist!!"

The energy of heaven and earth converged on Wei Wenguang's right fist, blooming with dazzling colorful colors.

Wei Wenqing muttered to himself: "It's finally time to use this trick, this time the Yan Demon King is dead!"

The Flame Demon King also felt the threat of this seven-colored light cluster, and roared again and again, and a huge flame with a diameter of more than ten meters suddenly burst out from his mouth!

"Die!!" Wei Wenguang roared angrily, and his fist shining with colorful light struck out with a punch!

Under the fist of the colorful light, the firelight seemed to be made of paper, and the fist instantly penetrated the firelight and directly bombarded the body of the Flame Demon King!

Thundered!!

An earth-shattering loud explosion erupted, and terrifying fluctuations surged out!

A large crater was blown out of the ground with a radius of several kilometers.

This may not be a large range, but the depth is several kilometers.

A shiny crystal-like thing fell from the sky, Wei Wenguang's figure flashed, and he took the crystal: "This kind of surging fire energy, it is not an exaggeration to say that it is a fire crystal. ”

"It's a pity that the energy is too violent, otherwise it wouldn't be impossible to take it out and let other fire attribute martial artists in the family cultivate. ”

Shaking his head, Wei Wenguang threw the Fire Demon Fire Crystal out.

"Second brother, let's go. ”

......

Unlike Han Fengwei Wenguang, Ji Weichen and the others were caught in a bitter battle.

"Extremely Cold Sky Ice Gun!!"

"Burning Sky Flame!!"

Ji Weichen and Xiao Qing worked together to perform a big move, and they could use this move with their cultivation in the early stage of the Heavenly Rank Nine Stars, and the power was only comparable to the peak level of the Heavenly Nine Stars.

The two are comparable to the peak level of the Heavenly Rank Nine Stars, and even the attacks that are faintly beyond are indeed not weak, and ordinary Heaven Rank Nine Star Peak Martial Artists dare not say that they can withstand the blow of the two of them.

But the opponent of the two of them was the Flame Demon King, who was equivalent to the strength of an ordinary Heavenly Rank ten-star early stage martial artist!

With a wave of the Flame Demon King's giant palm, the ice spear formed by the convergence of ice energy was cut off with one palm.

And the flames of the Burning Sky Flame hit the Flame Demon King, and the Flame Demon King even showed a look of great enjoyment.

The faces of the two of them became darker and darker.

"Xiao Qing, I know you still have stronger hole cards, in this situation, are you still going to hide them?" Ji Weichen yelled.

"Hmph, Ji Weichen, you don't need to talk about the old lady, don't you be the same. It's okay to ask the old lady to use the strongest tricks, but you have to do the same. Xiao Qing snorted coldly.

Ji Weichen's face froze, and he said hatefully: "Then we will shoot at the same time, I can see that even if it is the strongest hole card, there is only one person who may not be able to defeat this flame demon king." ”

The two glanced at each other with solemn expressions, and immediately, a wave of terrifying energy converged out.

"Ice Jiao Nine Heavens Break!!"

"Burning Sky Sevenfold Flame!!"

The two roared.

Ji Weichen's palms waved rapidly, forming a Dao remnant, and at the same time, a large amount of ice energy surged out, accompanied by a dragon roar, and the nine-headed thousand-foot ice Jiao roared out!

......

The third more!!
