Xuantian's cultivation broke through to the fifth level of the earth level realm, and the earth dragon veins were still shuttling underground.

Since the 'Earth Spirit King' has left this earth dragon vein behind and pointed out the way out, then this earth dragon vein will definitely return to the ground, it is only a matter of time.

Xuantian knew that the opportunity to be in the earth's leyline dragon's mouth was hard to come by, so he had to seize the time to cultivate, and after cultivating to break through the fivefold of the earth-level realm, Xuantian did not waste a little time, and continued to absorb and refine the earth's leyline essence, increase the true yuan, and consolidate the five-fold cultivation of the earth-level realm.

The earth's leyline essence here is surging, and in less than three days, Xuantian will be able to consolidate his cultivation to the peak of the fifth level, and he can impact the sixfold of the earth level realm, as long as the time is enough, it is very possible to rush to the seventh and eighth of the earth.

However, Xuantian's hopes were clearly disappointed.

After stepping into the fifth level of the earth level realm, about six hours later, Xuantian suddenly felt that the temperature around him became scorching, and it seemed that the earth dragon was pulsing towards a sea of fire.

The earth and rocks in front of him gradually turned from earthy yellow to red.

It didn't take long for the earth dragon vein to rush out of the earth and stone with Xuantian and appear in an extremely hot space.

Xuantian raised his eyes and looked at it, this is also an underground cave, although there is no sea of fire, but it is not much different, the ground is full of flowing magma, like boiling water, and from time to time there are clusters of red flames rising from the magma.

It is an underground lava cave, a place of solstice and heat, usually found under a volcano.

The heat wave in the air is monstrous, and the earth dragon vein is just an invisible air current, which can withstand the impact of the surging heat wave. It was like a cloud of mist, blown by a strong wind, and suddenly dissipated.

The first to bear the brunt was the dragon head of the dragon vein, which was the first to rush into the molten cavern, and was instantly torn apart by the heat wave, and Xuantian lost the protection of the dragon's mouth. Suddenly it fell from the sky.

Above Xuantian was a large area of molten slurry, the temperature was frighteningly high, and the sword light in Xuantian's body flashed. Suddenly, Edgeworth flew through the air for dozens of meters and landed on the crimson ground on the side of the lava cave.

Earth dragon vein. It was completely washed away by the heat wave, and the essence of the dragon veins was also integrated into the earth, stone and molten slurry.

The temperature of the heat wave in the air is very terrifying, but Xuantian, as a powerhouse of the Earth Rank Realm, can still endure it, not to mention, Xuantian's fire attribute qualification is super perfect level, and his resistance to flames is very strong, and the temperature in the molten cave has no effect on him, even if it falls into the molten lava. are able to resist for a moment and a half, and will not be immediately refined into ashes.

Seeing the earth dragon veins being washed away, Xuantian secretly screamed in his heart that it was a pity, there were many extremely deep underground dragon veins, but. The surface of the earth is very scarce, Xuantian does not have the means of 'Earth Spirit King', he can enter the ground for 10,000 meters to pursue the dragon vein, and it is not easy to find a dragon vein in the future.

However, since we have reached the underground molten cave. It's time to think about how to get out, the underground lava cave is connected to the volcano on the surface, and can pass through the crater and return to the surface.

The underground lava cave extends in all directions, it is very empty, Xuantian uses the divine pupil to watch for a while, the four directions are basically the same, and there are passages leading to the four directions, but Xuantian's divine pupil can see through the direction of the air flow in the void.

Although the heat wave in the air was surging and chaotic, there was still a trend in general, all of them flowed to the same place, and Xuantian believed that if he followed the direction of the air current, he would always reach the exit of the volcano.

The sword light in Xuantian's body flashed, and the sword flew, flying in the direction of the flow of air.

After flying for about a few thousand meters, Xuantian passed through one lava cave after another, and finally came to a huge space.

This is a space with a radius of thousands of kilometers, and the height is thousands of meters, and the top is not closed, but there is an exit with a diameter of more than 100 meters, and beyond the exit, there is a blue sky, obviously, that is the crater.

Beneath the crater, in the very center of the entire lava cave, the heat wave is at its most intense, the temperature is the hottest, and the air currents flow from all directions here, and then rush into the sky.

When a volcano erupts, the lava in the lava cave will be like the sea, and it will form a big explosion, burning a terrifying flame that can burn everything, and the heat wave will be thousands or 10,000 times larger than usual, and when it rushes out of the crater, it will bring up thick smoke and dust, and at that time, it will be visible to the naked eye.

Xuantian was not in a hurry to leave the crater, now was not the time for a volcanic eruption, and there was no threat to him here.

This is under the crater, in the center of the lava cave, where the lava tumbles most violently, and the red flames rise and fall.

Xuantian took out a secret book from the 'Space Ring' - "Earth Fire Seal Method".

This is a ground-level martial art he obtained from the 'Ghost Walker', the power is very powerful, and the Xuantian fire attribute qualification is super perfect, and the 'Earth Fire Seal Method' is particularly suitable for Xuantian's cultivation.

It's just that the environment for cultivating the 'Earth Fire Seal Method' is special, and it is necessary to absorb the fire of the earth evil in the underground molten cave to cultivate, and Xuantian has never found a good place.

This time I happened to come to such a huge volcanic lava cave, which was an excellent place to cultivate the 'Earth Fire Seal Method', and Xuantian naturally wanted to successfully cultivate the 'Earth Fire Seal Method' here.

Xuantian has cultivated a lot of martial arts, but in addition to the king-level divine skills, only the 'Twenty-four Star Sword' can be used, in public, Xuantian is not suitable for performing the King-level Divine Skill, only one set of 'Twenty-four Star Sword', and it is too monotonous, so it is very necessary to practice the 'Earth Fire Seal Method'.

Besides, Xuantian now has many enemies, and his main thing is to improve his cultivation and strength, and now his cultivation has just broken through the fifth level of the earth level realm, and it will take a while to improve to the sixth level of the earth level realm, and it is just here that he cultivates the 'Earth Fire Seal Method' to improve his strength.

Only when one's own cultivation and strength are strong can one walk in the land of China with confidence and fight with the enemy for a long time.

Xuantian stabilized his mind, and in the lava cave under the volcano, he began to retreat and practice the 'Earth Fire Seal Method', there are a large number of spirit stones in the 'Space Ring', which is enough for Xuantian to consume, and when he reaches the cultivation of the Earth Rank Realm, the spirit stones can completely replace food to supplement the consumption of the body, and the food is just to satisfy the desire of the tongue.

At the same time as harvesting the 'Earth Eye Pupil', Xuantian also harvested thousands of spirit stones, even if Xuantian was in retreat for ten years, there was no problem at all.

Xuantian has extremely high qualifications for the cultivation of fire-based martial arts, and it only took a few days to successfully cultivate the 'Earth Fire Seal Method'.

However, the 'Earth Fire Seal Method' needs to absorb a large amount of Earth Evil Fire, and the more Earth Fire you absorb, the deeper the fire and the more powerful it becomes.

Xuantian's current cultivation is one realm lower than the 'Ghost Walker' of the past, but his strength is far superior, but in terms of the power of the 'Earth Fire Seal Method', it is much inferior to the 'Ghost Walker'.

Although the power of the 'Earth Fire Seal Method' is related to the strength of the warrior's own true element, it is not completely related, and more importantly, it is how much Earth Evil Fire is absorbed.

If you want to improve your combat power, Xuantian's current 'Earth Fire Seal Method' is far from being successful, and it is completely inferior to the 'Twenty-Four Star Aspect Sword', and it must reach a certain level of fire to be of great use.

Fortunately, in this volcanic lava cave, the fire of the earth evil is inexhaustible, and Xuantian can be here, cultivating the 'Earth Fire Seal Method' to the limit before leaving.

As the days passed, Xuantian spent his seventeenth birthday unknowingly in the volcanic lava cave.

In June 970 of the new calendar of Shenzhou, Xuantian turned sixteen years old, and his cultivation had just stepped into the realm of the earth.

In June 971 of the new calendar of Shenzhou, Xuantian turned seventeen years old, and his cultivation had reached the fifth level of the earth level realm.

In one year's time, Xuantian's cultivation in the earth-level realm broke through four realms in a row, and in an average of three months, his cultivation improved by one realm.

It can be said that except for the 'Earth Spirit King', since ancient times, there has probably never been a genius in the land of Shenzhou who has cultivated so fast in the Earth Rank Realm, and even the legendary 'Immortal King' may not have such a cultivation speed.

The time soon came to the end of June, Xuantian had been cultivating in the volcanic lava cave for a month, and the fire of the 'Earth Fire Seal Method' was already very profound, even more profound than the attainments of the 'Ghost Walker'.

The final achievement of the 'Earth Fire Seal Method' was completely related to the quality of the Earth Evil Fire in the volcanic lava cave, and it was obvious that the volcanic molten cave where the 'Ghost Walker' used to practice the 'Earth Fire Seal Method' was not as good as the place where Xuantian was at the moment.

"In another three or five days, you will be able to cultivate the heat of the 'Earth Fire Seal Method' to the extreme, and the power is only afraid that it is not weaker than the ordinary Earth Rank Heavenly Fire, and it is not a small threat to the strong people in the late stage of the Earth Rank Realm and the peak, and the power of this Seal Law is no longer under the 'Twenty-Four Star Aspect Sword'. ”

Xuantian glanced at the crater at the top of the lava cave, with a smile on his face, he had been missing for a month, and he didn't know what had changed in the situation of the land of Shenzhou, and his enemies were afraid that they all thought he was dead.

Three days passed in a hurry, and Xuantian's cultivation of the 'Earth Fire Seal Method' was about to reach its limit.

For a month, the lava caverns were calm except for the scorching smell and tumbling lava.

But today, in the lava cave of the volcano, suddenly two warriors came and flew down from the crater.

Although Xuantian was cultivating, his spirit had never relaxed, he had become accustomed to the environment in the volcanic lava cave, and suddenly two martial artists came, destroying the peace, and Xuantian found out in an instant.

These are two martial artists in their twenties, who look six or seven points alike, they may be brothers, the age difference is about two or three years, the older one has the five-fold cultivation of the earth-level realm, and the other has the four-fold cultivation of the earth-level realm.

The lava cave is very huge, with a radius of more than 1,000 meters, Xuan Tianjiu has been in the molten cavern, almost fused with the scorching breath, and his body is also glowing with fiery red light under the irradiation of the red flames, which is not much different from the fiery red rock.

The young powerhouse who entered the volcanic lava cave obviously didn't notice Xuantian's existence, flew into the volcanic lava cave, and flew directly into a huge cave next to it with a height and width of more than 100 meters.
