Next to the intricate pattern, recessed in the stone wall, stood a coffin, and inside the coffin, stood a dried corpse, motionless and without any breath.

Presumably, it was the body of the black shadow.

Xuantian's gaze returned to the 'Heart of Thunder' again, and with a wave of his palm, a sword light burst out, which was the 'Ground-level Spirit Sword'.

With a bang, the 'Ground-level Spirit Sword' struck the transparent object outside the 'Heart of Thunder', and there seemed to be an invisible force that blocked the attack of the 'Ground-level Spirit Sword', and the invincible 'Ground-level Spirit Sword' failed to leave a single mark on the transparent object.

Xuantian tried (the fastest update) a few more times, but in vain.

It seems that with Xuantian's current cultivation, it is impossible to break through this thing with the 'Earth-level Spirit Sword' and take out the 'Heart of Thunder'.

Now Xuantian uses the 'Ground-level Spirit Sword' only by relying on the sharpness of the 'Ground-level Spirit Sword', and his cultivation cannot fully exert the maximum attack power of the 'Ground-level Spirit Sword', just like the earth-level treasure weapon, in the hands of the powerhouse of the earth-level realm, the attack power is far stronger than that in the hands of the martial artist of the innate realm, a reason.

"This transparent object is too strong, even if I reach the late stage of the innate realm, there is no hope of breaking it, I don't know if it is possible to step into the earth level realm, the 'thunder heart' inside must be above the fourth level, corresponding to the cultivation of the earth level realm, if I can get out of trouble, I can come back to explore it in the future." ”

Xuantian didn't pay much attention to the 'Heart of Thunder', and his eyes fell on the complex patterns on the ground again.

He got the first, middle, and lower volumes of the 'Thunder Mind'. Although there is no cultivation, the content has already been watched, and it seems, in the 'Thunder Heart Method'. This pattern is recorded, and it is a kind of true qi flow route.

Perhaps, there is something between the 'Thunder Heart Method' and this complex pattern [Chapter 197] Xuanyuan Chuxue (I) Four More Requests for a Monthly Pass, and can leave here.

Xuantian returned to the spacious room, calmed down, and began to practice the 'Thunder Heart Method'.

Xuantian has a perfect-level thunder attribute, and when he cultivates, he should be very fast.

But. The speed of cultivation was still beyond Xuantian's expectations.

On the first day, Xuantian actually cultivated the 'Thunder Heart Method' to the fourth layer, such a speed. It was many times faster than when he had cultivated the 'Nine Flames Xuanhuo Gong'.

"Why is the speed so fast?" Xuantian was also taken aback: "The fire attribute of my physique is super perfect level, one grade higher than the thunder attribute, and the cultivation speed is fast enough, but it is still much slower than the 'Thunder Heart Method'." Could it be that if there is a 'Thunder Heart' in the body, the speed of cultivating the 'Thunder Heart Method' is much faster?"

Xuantian's guess was correct. The cultivation of the 'Thunder Heart Method' was originally the cultivation of the power of thunder within the body. Condense the 'Heart of Thunder' if there is already a 'Heart of Thunder'. When you cultivate, it's like someone pushing, and the speed is very fast.

The upper volume of the 'Thunder Heart Method' can only condense the middle volume of the first-level 'Thunder Heart', and can condense the second-level 'Thunder Heart'.

Now there is a second-level 'Thunder Heart' in the Xuantian Body, not only is the cultivation of the fourth layer of the 'Thunder Heart Method' in the upper volume extremely fast, but even the fourth layer of the middle volume is equally fast.

However, the cultivation difficulty of the middle scroll is still much more difficult than the previous volume, and two days later, Xuan Tiantian cultivated to the fifth layer.

After another four days, he cultivated to the sixth layer, and after another six days, he cultivated to the seventh layer, and after another nine days, he cultivated the middle scroll to the sixth level, reaching the eighth layer.

It has only been 22 days in total, and the middle volume of the 'Thunder Heart Method' has been cultivated to the eighth layer, the eighth layer, which happens to correspond to the sixth layer of the innate realm, and if you want to break through the seventh level of the first innate realm, you need to cultivate the next volume of the 'Thunder Heart Method', and you can successfully cultivate the ninth layer, or you can cultivate the 'Nine Flames Xuanhuo Gong' to the ninth layer, which is also possible.

As long as there is any kind of exercise that breaks through to the corresponding level, then the martial artist's cultivation will break through, and then he will practice other exercises, because the cultivation has already arrived, and the speed will be much faster.

The speed of cultivating the 'Thunder Heart Method' was so fast, and Xuantian's cultivation had already reached the sixth level of the Innate Realm, which was also a major reason.

Cultivating the 'Thunder Heart Method' to the eighth layer, the route of luck will be able to form that complex pattern, Xuantian walked towards the pitch-black cave and stood on top of that complex pattern.

The innate true qi in the body of the 'Thunder Heart Method' is transformed into the power of thunder, gushing out from the soles of the feet and spreading along the lines of the pattern.

Soon, the thunder and lightning enveloped the entire complex pattern, and some kind of prohibition was triggered, and Xuantian felt a weight on his body, but the entire altar underground flew up.

There was a strong light emitting from the altar, enveloping Xuantian's body, which was indestructible, and the ground was penetrated, moving quickly towards the ground.

Thunder Mountain Range, a certain area with dense thunder and lightning, a radius of more than thirty miles, at the southern edge, a jade-crowned young man, holding a thunder sword in his hand, is practicing a sword technique in the edge of thunder and lightning.

The jade-crowned boy is the young master of the free and easy Heng Yun.

The cultivated sword technique, to be exact, is not a sword technique, but a set of sword duels, the integration of exercises and swordsmanship, is the sword duel, the name 'True Thunder Sword Duel' is a set of extremely powerful Xuan-level high-grade sword skills of the Xiaoyao Sword Sect.

The best place to practice the 'True Thunder Sword Duel' is among the thunder and lightning, and there are thunder and lightning everywhere in the Thunder Mountain Range, which is a good place to practice the 'True Thunder Sword Duel'.

Every disciple of the Joyful Sword Sect who cultivates the 'True Thunder Sword Duel' will almost come to the Thunder Mountain Range to refine the sword, which can get twice the result with half the effort.

With the sword momentum of the horizontal clouds, thunder and lightning swam on the tip of the sword, and each sword stabbed out, containing the power of explosive thunder, and the momentum was terrifying.

The power of that explosive thunder was enough to kill any martial artist below the late stage of the Innate Realm in an instant, and even, a sevenfold martial artist of the Innate Realm would be seriously injured without death.

Ren Hengxing and Ren are domineering, they stand outside the thunder and lightning, for the Heng gradually cloud protector, the 'True Thunder Sword Duel' is the most powerful Xuan-level sword skill of the Xiaoyao Sword Sect, not an important person, cannot be cultivated, the Ren brothers will not, they can only stand outside the thunder and lightning.

The Easy Sword Sect received Heng Wanyun's order, and sent many martial artists from the late stage of the Innate Realm to the Thunder Mountain Range, and under the leadership of Heng Wanyun, they launched a search on the periphery of the Thunder Mountain Range, which lasted for ten days, but no trace of Xuantian was found.

No one was found, so Heng Chuanyun had no choice but to let the others go back, leaving only the Ren brothers to accompany him to practice swords in the Thunder Mountain Range.

Now, after another ten days, practicing swords under thunder and lightning has more than five times the effect of usual cultivation, and Heng Wanyun has good qualifications, and he has already gained something.

Beyond the northern edge of this thunderbolt region, about thirty miles away from the three of Heng Wanyun, stood a stunning woman dressed in white like snow, holding a black cat in her arms.

This cat is a little special, and it actually has a pair of small wings on its back.

This person and a cat, all looking ahead, in the dense thunder and lightning.

This thunder and lightning area, the thunder and lightning in the north, is much thicker and more powerful than the south, and at this moment, in the midst of the thunder and lightning, there is a black tiger about two meters long.

This black tiger also has a pair of wings on its back.

The powerful thunder and lightning slashed at the black tiger's body, and the current shrouded the black tiger's body, but the black tiger had an expression of enjoyment, and there was no pain, it seemed that the thunder and lightning were a kind of tonic for the black tiger, refining the black tiger's body-

In this area of thunder and lightning, three miles to the east, there is a circular mountain peak, forming a square basin with a radius of about 1,000 kilometers.

At all times, there are thunderbolts, splitting down in this basin, densely packed, the distance between each thunderbolt is not more than ten meters, and the power of thunder and lightning is much thicker than ordinary thunder and lightning.

Although the scope of this area is small, it is also a forbidden area in the Thunder Mountain Range, even if you eat the 'Thunder Huā', you can't stop the thunder and lightning in the basin, and if you break in, there is only a dead end.

No one knew that in the center of this basin, there was an altar with some extremely complex patterns carved on it, which were exactly the same as the altar patterns that Xuantian saw in the fourth-layer cave of the Thunder Palace Treasure House.

Xuantian saw that there were earth and stones all around, and he was walking quickly through the ground, but the light from the altar enveloped him, and a trace of flying sand and earth and stones could not enter the light shield.

After hundreds of breaths, all of a sudden, all the earth and stones around disappeared, and in front, countless thunderbolts appeared around, the altar stopped, and Xuantian appeared on the ground, which was the altar in the middle of the basin.

The pillar of light emitted by the altar rose to the sky, scattering all the dark clouds in the sky, and the thunder and lightning were also eclipsed under this pillar of light.

Heng Yanyun, who was practicing his sword in the thunder and lightning, and the nearby Ren brothers, were all attracted by the sudden appearance of the pillar of light.

Heng Yanyun suddenly walked out of the thunder and lightning, looked at the direction where the pillar of light was, full of interest, and said, "Go and take a look." ”

"Yes, young master!" the Ren brothers were bored, but also full of interest.

The three of them rushed in the direction where Xuantian was.

To the north of the fierce land, the black tiger who tempered his body in the thunder and lightning, at the moment when the pillar of light appeared, suddenly looked stunned, looked at the east, full of joy, and his body instantly turned small, only more than a foot long, like a kitten, very similar to the black cat in the arms of the stunning woman in white clothes like snow, and the body was vertical, and ran towards the east.

"Hey, little tiger, you're playful again. The stunning woman in white as snow shouted.

But the black tiger was extremely fast, and disappeared in a blink of an eye, and the black cat in the arms of the stunning woman opened its eyes and looked at it, and then closed its eyes in boredom.

The stunning woman dressed in white like snow sighed and walked in the direction where the black tiger was running.

She walked very slowly, easily and naturally, but when she stepped out, it was like shrinking the ground into inches, and the mountains and rivers retreated rapidly under her feet, and with a light step, it was thousands of meters. ！！！
