After separating from the crowd, Shi Chen's master and apprentice began to go in one direction.

Xing Ruwan and Xiaoyu sensed that there was a thunder force in front of them, which was absolutely extraordinary. is also a thunder linggen, and the ability to perceive things related to thunder linggen is much stronger than ordinary people.

As expected, the three of them came to a cave mansion that contained infinite thunder power. Xiaoyu's body is too big to enter. simply broke a hole in the cave, and the entire cave was reflected in the sky of the ancient ruins.

"It's ...... A thunder sword?" Xing Ruwan said in surprise, unexpectedly that the entire cave mansion had nothing but this sword.

"Will it be dangerous?" Xiaoyu asked vigilantly on the side.

After the experience of being taken away by the Blood Emperor before, maybe this sword really hides a mystery, and these predecessors in the primeval period like to play tricks and be opportunistic.

"There is only this sword here, could it be said that someone has left it here? It stands to reason that this sword should be inserted under the infinite thunder array to prevent others from taking it away, is it really a fraud?" Shi Chen frowned, he was also confused, and the thoughts of the ancients were difficult to suspect.

Xiaoyu's primeval thunder spirit root is the most capable of sensing this kind of thunder weapon, at this time, since I don't know the opening path and depth of this sword, it is better to try it first.

With the next moment, Xiaoyu's claw with infinite thunder intent fell, slapping on the thunder sword. The thunder sword didn't move, and after a while, the thunder suddenly exploded.

Shi Chen and the others were startled, not knowing what kind of character Xiaoyu's claw had angered.

The thunder sword shot a thunderbolt into the sky, and suddenly the thunderclouds were dense, and lightning flashed and thundered. The entire area was shrouded in black, oppressive thunderclouds.

A white-haired old man suddenly appeared in the thunder sword, just a phantom. Slowly floating into the air, staring at the three monks in front of him, he stroked a handful of white long beards, and began to get to the point: "Ancient Thunder Spirit Root, the best Thunder Spirit Root, not bad." This thunder array of mine is an ancient thunder array, called the Extreme Thunder. After this formation, you can pull out the thunder sword and get my inheritance. I am the Emperor of the Emperor Realm......"

Shi Chen and the three of them watched in a daze at the appearance of this old man in a dignified manner, and left in a dignified manner.

"Thunder Emperor......" Shi Chen thought thoughtfully, the previous phantom should be something similar to a mirror ball, and the Thunder Sword released this huge thunder array, there should be no fake. There should no longer be a soul similar to the Blood Emperor in this Thunder Sword, this Thunder Emperor is definitely still alive in the Emperor Realm, maybe waiting for someone to take his Thunder Sword to the Emperor Realm to find him. So now, this thunder sword is not threatening.

"Master, the Extreme Thunder Array is here. Xing Ruwan shouted to the contemplative master, and she flew away from the sky, meeting the countless thunderbolts with her bare hands.

"Master, you stay here first, I feel it, this is also my chance!" Xiaoyu said, her eyes looking at Shi Chen, begging her master to agree.

"Okay, Xiaoyu, go ahead, take care of Ru Wan......" Shi Chen asked, knowing that his apprentice had the art of refining the body, but after all, this thunder array was in the hands of the person who claimed to be the Thunder Emperor in the primeval period, it was not trivial, it was better to be careful.

"Got it. Xiaoyu responded, put the master down safely, and then went straight to the thunderstorm in the sky, catching up with Xing Ruwan's pace.

Seeing Xiaoyu flying, Xing Ruwan tiptoed, stepped on Xiaoyu, and had a duel with the thunderstorm in front of her.

With the continuous thunder, Xing Ruwan frantically operated the Great Thunder Alchemy Technique, absorbing all these falling thunderbolts and using them to refine her physique, making the Great Thunder Alchemy Technique go to the next level.

Xiaoyu fell into a deep understanding, summoned his own deep blue primeval thunder dragon array, and confronted it, precipitated, run-in, absorbed, and enhanced......

Shi Chen had no choice but to sit on the ground alone, looking at the crazy two worriedly, protecting the Dharma for them. With the slightest movement, he immediately stepped on the Qingyu Sword and went to rescue the two.

I have to say that Shi Chen has experienced all these years of ups and downs, and his nerves are indeed a little hypersensitive, and this extreme thunder array will only be of great benefit to the two of them, and there is absolutely no harm at all.

After a long baptism of extreme thunder, Xing Ruwan's Great Thunder Alchemy Technique was taken to the next level, and her body became tougher. After the tempering of the thunder array, countless blood and impurities were eliminated from the body, and Xing Ruwan absorbed the spiritual power of the falling thunder while running the rain god decision.

At this moment, the cultivation skyrocketed as if it was a cross-level.

Infant Becomes 2nd Floor...... Infant Becomes Four-Layer ...... Infant Six-Layer ...... Infant Transformation Nine-Layer ...... Infant Peak......

As the last thunder of the extreme thunder fell, Xing Ruwan broke through this layer of shackles and attracted the Thunder Tribulation.

As soon as the extreme thunder dispersed, the sky gathered again to win the thunder tribulation, not much to say, according to the previous thunder array, one after another fell on Xing Ruwan's body.

Xing Ruwan then fought with the Thunder Tribulation, still with her bare hands, but under this Thunder Tribulation, it was not false at all.

For a full fifteen waves of thunder tribulation, Xing Ruwan exhaled a breath of turbid breath and let out a long sigh, and Xiuwei finally reached the realm of victory.

Xiaoyu is not bad, and she has already reached the eighth floor, compared to Xing Ruwan's growth, she is slightly worse. Because it took me more time to have an epiphany.

This thunder array is more domineering than his own primeval thunder dragon array, with more thunder power, higher damage, and the thunderclouds gathered are more wide. Different from his own blue thundercloud array, this extreme thundercloud array is similar to the thunderstorm and the rain summoning technique, both are the same black and oppressive thunderclouds, this is the natural color that the thunder array should have.

With a long roar, the Polar Thunder Array appeared in the sky again, and Xiaoyu had already absorbed the Polar Thunder Array into his Ancient Thunder Dragon Array in perfect harmony.

"Xiaoyu, you're amazing!" Feeling the change in Xiaoyu's thunderstorm, Xing Ruwan said happily.

Shi Chen looked at the two people who had benefited a lot in the sky, and a smile appeared on the corner of his mouth, feeling equally happy for the two of them. I didn't expect that it took so much effort for me to go from being an infant to winning the championship, and the apprentice actually completed it with an ancient thunder array, so talented, where could she be as stupid as she was in the Blue Cloud Sect for seventy years?

The light rain carried Xing Ruwan from the sky where the thunderstorm had dissipated, and returned to Shi Chen's side.

"Master, I've passed through the Thunder Emperor's Extreme Thunder Array, I'm going to draw the Thunder Sword?" Xing Ruwan asked happily, her little eyes flashing in front of Master.

"Go quickly, don't force it if you can't pull it out. "Shi Chen Dao, all this is the creation of the apprentice, so it seems that this Thunder Emperor is not bad, and he did not set up his cave mansion as a cave full of mysteries and dangers. Compared with the original Rain God Temple and the Blood Emperor Cave Mansion, it is simply a completely different style, a clear stream in the cave world.

Although Shi Chen was relieved that his apprentice went to pull out the Thunder Emperor's sword, he still protected the Dharma with Xiaoyu not far from him, for fear that there would be some abnormalities and he would not have time to react.
