The rumbling tide of energy appeared, and the sound from far and near continued to enter Sun Xiaofei's ears, Sun Xiaofei hurriedly took Xiaohui to hide in the cave, looked back behind him, and immediately saw an extremely shocking scene. At this moment, the magma world became very riotous, and the flames were churning everywhere, and the hot lava mixed with the flames was like a rolling sea of fire, and the sound was terrifying, and it launched a ferocious impact on all sides.

Sun Xiaofei was also very surprised when he saw such an amazing momentum as the energy tide. He didn't dare to hesitate at all, and immediately activated all the defensive formations and prohibitions he had originally arranged. In an instant, a series of strong defenses and prohibitions were formed at the entrance of the cave, and the entire entrance of the cave was covered by layers of light curtains.

Sun Xiaofei had arranged so many defenses in a very short period of time, and he still felt a little uneasy, and the Nine-Character True Determination Seal was cast, calling Shang Xiaohui to also cast a defensive spell, and joining forces with him to add more defenses to resist the shock wave generated by the energy tide this time.

"Boom!"

The magma was mixed with blazing flames, and in a very shocking way, it launched an impact on the cave where Sun Xiaofei was. The defensive formation outside the cave was destroyed by this huge shock wave almost instantly, and the sea of fire was slightly blocked, and then surged into the cave.

The defense laid by Sun Xiaofei was not very effective in the face of this wave of flame energy with such a fierce impact. Sun Xiaofei and Xiaohui looked at each other with nervous expressions on their faces, and the defensive formations and prohibitions in front of them were constantly suffering from the impact and gradually collapsing, and they were secretly praying in their hearts that these defensive measures could withstand this impact.

For the sake of his own safety, Sun Xiaofei sacrificed the Sky Sword, turning into a curtain of light in front of him to wrap him and Xiaohui, and several other war swords were on standby at any time, just in case, the Yuan Ying in the Consciousness Sea had already put the dragon scale armor on his body, and he could teleport and escape at any time to avoid the danger this time.

The impact of the energy tide formation destroyed the formations and prohibitions arranged by Sun Xiaofei, you must know that Sun Xiaofei's formations can even withstand the attacks of the battle emperor-level masters for a while, but now they are easily destroyed.

Sun Xiaofei did not exchange fire rock for top-level defensive weapons like Courter and others. It's not that he doesn't have money, it's that he has enough confidence in himself. This confidence comes from his knowledge and understanding of his own strength. firmly believes that even if he has no defensive weapons, with the exercises he said to cultivate, the various magic weapons and equipment on his body, and the dragon scale armor of the War Emperor level, it is enough for him to resist most of the dangers.

After the layers of defensive formations and prohibitions were gradually weakened, the sea of magma and fire formed by the energy tide began to weaken after destroying more than a dozen defenses in a row, and there was no longer as fierce attack power as the first wave of impact.

The tide of energy comes and goes as fast as it comes, and the wave of shock in front continues to move forward, and the shock behind it has begun to subside.

This wave of impact was finally resisted by the Sky Sword, and the earth spirit power contained in the Sky Sword turned into a thick earth wall, no matter how the magma and fire sea impacted, it could not destroy this defense.

Sun Xiaofei couldn't help but breathe a sigh of relief when he saw this situation, and at the same time secretly rejoiced in his heart. The sea of magma and fire stopped less than a few meters away from him, and the scorching smell emanated from all parts of the cavern under the hot heat.

Although Sun Xiaofei and Xiaohui both thought that they would have a way to survive even if they fell into the sea of fire. However, they don't want to go inside and try it out. They were not afraid of the flames, but what was terrible was the continuous and huge impact and the terrible pressure in the magma.

Entering the sea of fire, many life-saving methods are useless, and can only be passively defended, bearing the endless oppression of lava and the burning of flames.

The dark red lava began to slowly retreat, leaving behind a layer of black-brown ash that swirled through the cavern with a scorching smell of sulphur.

Xiaohui's tense nerves relaxed, and when he saw the energy tide retreating, his soul transmitted to Sun Xiaofei and asked, "Big brother, it's not coming anymore, can we go out?"

"I don't know, let's be careful. Don't be careless, I'll take a look at it first. Sun Xiaofei shook his head silently and said.

After Sun Xiaofei finished speaking, he closed his eyes slightly, and his soul power seeped out from the center of his eyebrows and spread out towards the outside of the cave.

In an instant, the scene of the magma world outside the cave appeared in his mind. As the detection range of soul power gradually expanded, Sun Xiaofei's expression gradually became solemn, and the magma world outside was not as calm as he imagined, it was still tumbling, as if something was brewing.

Sun Xiaofei couldn't help but gasp after thinking about it, his previous experience told him that he had come to an astonishing conclusion, this energy tide is continuous, and the impact of each round is big and small, and they will encounter the next round of impact.

Sun Xiaofei immediately withdrew the diffused soul power and warned Xiaohui. "Xiaohui, hurry! Get ready, the energy tide is coming again. ”

When Xiaohui heard this, he couldn't help but be taken aback, jumped up and shouted, "What!

Sun Xiaofei didn't care about explaining more to Xiaohui, and immediately began to rearrange various defensive arrays and prohibitions, and through the scene of resisting the impact of the energy tide just now, it also made Sun Xiaofei re-understand what flaws and loopholes he had arranged in the magic circle.

This time, he was more careful in arranging, the defensive force was much stronger than last time, and the formations complemented each other and played a role in amplifying each other, so that the defensive power of the formation was greatly enhanced, and he was more confident in resisting the next impact.

"Bang!"

The magma world began to erupt from time to time with a violent explosion, magma and flames were constantly surging and churning, and this wave of impact gradually formed, slowly crushing towards Sun Xiaofei. With such a roaring sound of lava rolling and flames, even Sun Xiaofei, who had seen this scene, suddenly felt a heavy oppression in his heart.

Sun Xiaofei and Xiaohui watched the sea of fire that rushed over and the defensive formation that had been built collide together, and a tingling sound sounded, Sun Xiaofei looked at all this with a solemn face, ready to deal with it at any time.

Fortunately, this time he did a good job of defensive measures, stubbornly resisting the impact of this wave.

As Sun Xiaofei expected, as long as he could withstand the impact of the first wave of the energy tide, the continuous impact behind him was not enough to fear.

This time, the energy tide continued to erupt several times, and each wave of impact was sometimes large and sometimes small, which made Sun Xiaofei exhausted and very tired, but fortunately, all the impacts were resisted by the defensive formation, and did not bring him any damage.

The only trouble was that he had to quickly repair the destroyed formation and rearrange the layers of defense at every time the energy tide receded.

After a few days, the tide of energy subsided and never reappeared. Sun Xiaofei and Xiaohui cleaned up the cave again, cleaned up a lot of garbage and debris, and continued their cultivation days.

After going through the matter of the energy tide, Sun Xiaofei also gained some enlightenment from it, and combined with some experiences in cultivation, he had a deeper understanding of the comprehension of the laws of the fire system, and his cultivation was twice the result with half the effort, making him go further on the road of pursuing the peak of cultivation.

Sun Xiaofei put everything aside, his whole body and mind devoted himself to the comprehension of the power of the fire system, and pursued the origin of the fire power.

The days passed like this, Sun Xiaofei sat in the cave and cultivated, constantly absorbing the abundant fire spiritual power here, and the innate true yuan power in his body slowly and abnormally grew. A few months later, Sun Xiaofei's cultivation had broken through and entered the middle stage of the Yuan Infant.

During his cultivation, he would also appear outside the entrance of the cave from time to time to observe the various changes in the flames in the magma world. Sometimes he would also have a battle with Xiaohui, and through this mutual learning between the two, they confirmed each other's cultivation experience, which accelerated Sun Xiaofei's comprehension of the true meaning of the origin of fire power.

Half a year passed in the blink of an eye, and during this time, the energy tide appeared a total of three times, and the interval was different each time. Sometimes it is long and short, it erupts once every three or four months, and when it is short, it erupts in less than a few days.

Relying on the thoughtful defensive arrangement to resist every energy tide, Sun Xiaofei has not left the scope of the cave for half a year. For such a long time, he also gradually figured out the law of the energy tide that erupted in the magma world.

The energy tide rose and contracted, as if touching a place in Sun Xiaofei's heart, and suddenly a spiritual light flashed in his heart, Sun Xiaofei did not miss this opportunity in vain, and suddenly grasped this spiritual light and woke up, and the cultivation difficulties that had been trapping him for a long time were suddenly solved.

Sun Xiaofei watched the changes in the magma world and realized the true meaning of the cultivation of the power of the fire system. The energy tide that erupts in the magma world is just a manifestation of the change in the form of the fire power. When any power reaches saturation, in order to be able to improve its own level, it will adopt an extreme way of dealing with it, that is, to release a part of the excess and useless energy and absorb new and more powerful energy, so as to maintain an absolute advantage in the level of strength.

If you want to replace a bigger and better bottle, you have to pour out the water from the old bottle before you can pour it back into the bigger new bottle. After understanding the mystery, Sun Xiaofei knew what he should do in the future.

Sun Xiaofei said to Xiaohui, and then entered the magma world alone, and he wanted to seek a breakthrough in the blazing magma world. On this day, maybe he will succeed, or maybe he will be swallowed by magma, Sun Xiaofei has no hesitation about his choice, there has never been room for bargaining in cultivation, and since he has decided, he no longer regrets it.
