It took ten years for Xue Zhen to slowly open his eyes, but at this moment, his face did not have the kind of joy that he should have, and his eyebrows were shallow, and he touched his chin, and thought carefully.

"Is this really so difficult in the cultivation of Xuan Tiancong, although there is success in cultivation, but the effect is really not very good, the sensitivity of a pair of Tiancong's ears seems to have reached a certain insurmountable bottleneck, and it is impossible to enter the next step!" Xue Zhen thought secretly in his heart.

It turned out that in the past ten years, Xue Zhen did not recover from his cultivation, but Xue Zhen did not open his eyes for this reason, and listened to the outside world with his pair of Tiancong ears in the middle of cultivation, and indeed the hearing of both ears could be improved, but after three years of cultivation, he naturally reached a bottleneck, and in the next seven years, there was not even the slightest progress, and as a last resort, Xue Zhen had to temporarily stop.

At this time, Xue Zhen naturally did not just put his mind in his ears, but looked around his body with divine thoughts and eyes, and some strange feelings immediately surged into Xue Zhen's heart.

"Some time ago, the same is true for the heart refining of that kind of treasure, I have never heard of a monk who can't refine the treasure in the heart, as long as the cultivation is enough, the heart refining treasure is a natural thing, but on me, it will actually trigger the backlash, the problem is not shallow, is it ......?"

Xue Zhen muttered softly, and in the end, Xue Zhen didn't say a word, but he put his eyes on his body in a gray and white robe, and with a frown, Xue Zhen sighed softly.

In this way, it seems that only by taking some time to re-condense a physical body, a physical body that truly belongs to oneself, may be able to achieve the desired effect. Xue Zhen speculated to himself in a deep voice.

However, Xue Zhen's eyes fell on the blood-red crystal pill at his dantian, but he couldn't help but laugh bitterly, while Xue Zhen let out a long breath and slowly began to clean up his mood.

Gradually, Xue Zhen entered the state of perceiving heaven and earth, and the wind of the body blew gently, but Xue Zhen naturally did not rush to pinch out the silk of the law of destruction at this moment, but just maintained the state of perception and continued to continue, and the wind of the body was intermittent until Xue Zhen was able to completely control it and condense it in the body, and Xue Zhen actually spent more than one hundred and twenty years again.

Xue Zhen, who opened his eyes again at this moment, flickered through the Twin Immortal Mound Forbidden Array, and was in a higher mid-air, the expression on Xue Zhen's face was extremely relaxed, and a certain feeling arose, and between the changes in Xue Zhen's palm, a colorless silk of fluctuation laws about five inches long had already appeared in his palm.

Pushing away with the trick, Xue Zhen watched as this colorless silk of fluctuation law was wiped into a small mound of earth, falling straight to a depth of thousands of feet, indestructible, until it gradually disappeared into Xue Zhen's divine thoughts.

"The power of the law is indeed good, but such a weak state, relying on it to deal with the Thunder Tribulation, is really too thin!" Xue Zhen sighed softly.

After the test, Xue Zhen returned to the Twin Immortal Tomb Forbidden Array, and the sealed Thunder Essence Stone was immediately transferred out by Xue Zhen, and the magic jade ring of the Yuan Explosion Thunder Bead was also called out by Xue Zhen, Xue Zhen looked at it carefully several times, and because he had studied it repeatedly many times before, Xue Zhen soon began a corresponding refining process.

The Thunder Essence Stone is actually a certain kind of stone that can store thunder power, if it is just that kind of special stone without thunder power, or only in the face of some kind of heavenly thunder, and there is no corresponding special stone as a store, this kind of Yuan Explosion Thunder Bead cannot be formed.

Untied the corresponding seal, Xue Zhen carefully inspected this thunder essence stone, only to see that the surface of this thunder essence stone, which is not too big, is like a small insect, and the electric wire thunder power that conjures up the color of gold and silver "crackles" from time to time, and on the whole thunder essence stone, such electric wire thunder power is only about seven or eight, and then counting the hidden thunder inside, that is, about ten, this kind of number is too rare, and it is not easy to use it to solve the thunder.

This is also why Xue Zhen wants to ask Yuan Huan if he has any other Thunder Essence Stones, because if Xue Zhen is not mistaken, there should be some of these Thunder Essence Stones, but Xue Zhen still can't get the answer he wants in the end.

At this moment, after Xue Zhen looked at the Thunder Essence Stone for a while, the unusually familiar feeling condensed, Xue Zhen's body, the understanding of the law that was already very proficient in the industry jumped into his mind, however, Xue Zhen did not want to pinch out the corresponding law silk, concentrating on the thunder essence stone fluttering in front of him, Xue Zhen's hands were slightly wrapped on both sides of the thunder essence stone, and there was no contact, but his hands were swinging according to the law of the laws of heaven and earth, and he was still changing in the weird way mentioned in the spell, a kind of powerless flash, but he was soon sucked into the thunder essence stone。

Such a kind of unexplained power appeared, and was sucked in by the Thunder Spirit Stone, Xue Zhen almost ran this trick for nearly half an hour, and the kind of soreness and softness caused by the long-term pressure of the law on his body, Xue Zhen had no choice but to stop.

"The exertion of such a law power is really difficult for some strong people, fortunately it can be suspended, but, according to the records of the spell, the time to persist is nearly twice as much as that mentioned in the spell, perhaps, it will take another time to complete!" Xue Zhen stretched his muscles and bones, and then looked at the Thunder Spirit Stone and said lightly.

In the following time, Xue Zhen breathed a little for a long time, and then began the second law sacrifice, seeing that the Thunder Essence Stone was inhaled little by little with the power of the Thunder Essence Fortune, until finally, when the Thunder Essence Stone could no longer be inhaled, when Xue Zhen received the Formula, the Thunder Essence Stone turned into a black crystal bead slightly smaller than the fist, Xue Zhen actually roared into the sky, and the howling sound stopped abruptly for a long time.

"Haha! It's finally done, the Yuan Explosion Thunder Bead, I hope it can come in handy in the Thunder Tribulation!" Xue Zhen exclaimed excitedly.

Subsequently, Xue Zhen deliberately checked the Yuan Explosion Thunder Bead according to the inspection standards mentioned in the spell, and the quality of it was also relatively high, except for the sealing technique mentioned in the spell, Xue Zhen added several prohibitions before he put it in the storage ring with confidence.

"Maybe! Now is the time!" Xue Zhen regained for a long time, and when he opened his eyes, there was a certain kind of affirmative light in his eyes, and he muttered.
