In the dimly lit cave, Zhao Xiaoyi's footsteps paused at the end of the cave, with a look of horror in his eyes, and he looked towards the end of the cave.

At the end of the cave, there is a huge bronze gate, the gate is composed of two, it is more than ten meters high, and before the body is reached, you can feel a majestic and simple atmosphere, such a large bronze gate, Zhao Xiaoyi doesn't know which cow is standing, let alone how to get in, if you want to use a space ring, I'm afraid the general space ring can't do it!

Yanxi's figure also flashed out at this time, and her beautiful eyes looked at the bronze gate in front of her, and even her face was full of horror.

"This gate inheritance should be very old, and there are still remnants of the formation on it. Yan Xi's beautiful eyes stared at the tall bronze gate, and then said softly.

"Formation? How do you open it?" Zhao Xiaoyi's eyes narrowed slightly, there was a snow bear outside, this was the only place they could get out, if they couldn't open this bronze gate, they would only be trapped here.

"You stand back, I'll try, but there's no guarantee that I'll be able to get it open. Yanxi's face was solemn, and she said to Zhao Xiaoyi, and then she took a step forward, her eyes staring at the bronze gate.

Seeing that Yanxi was about to make a move, Zhao Xiaoyi didn't interfere with her, her figure withdrew slightly, and her eyes fell to the bronze gate.

Slender arms poked out of the sleeve robe, Yanxi didn't look away, a handprint quickly formed in her hand, and with the formation of her handprint, a light also appeared on her palms in an instant.

The brilliance became more and more dazzling, and after it reached a certain level, Yanxi waved her arms, and a pillar of energy light suddenly hit the bronze gate.

As soon as the beam of light touched the bronze gate, all of a sudden, the originally silent bronze gate suddenly burst into a burst of brilliant light, the light was blue-gray, like a barrier, enveloping the bronze gate, making De Yanxi's beam impenetrable.

"Sure enough, there is a formation protection!" Looking at the blue-gray light flickering on the bronze gate, Zhao Xiaoyi on the side muttered, it was as calm as water just now, but now the bronze gate is showing that protective barrier, this kind of hidden formation, it is really difficult for ordinary people to find it.

Yanxi didn't seem to hear Zhao Xiaoyi's voice, her attention was all on that layer of brilliance, judging from the fluctuations in the brilliance, it was indeed a formation that was not weak, but after years of silence, it was now a lot weaker, and it was not impossible to break it.

Yanxi's arm shook slightly, and immediately after, the beam of light that hit the bronze gate thickened again, and the surrounding fluctuations were also violent.

And as Yanxi's strength increased, Zhao Xiaoyi saw that the barrier above the bronze gate was also rippling with a layer of energy ripples at this time, and the place where Yanxi's beam was impacted had the meaning of depression.

The fluctuations on the barrier became larger and larger, and Yanxi's beam of light seemed to have a huge destructive liliang, which made the barrier tremble, and after a while, a small crack appeared on the barrier.

There are more and more cracks, wider and wider, like spider webs spread over the barrier, the energy ripples on the barrier want to repair these cracks, but its speed is not able to catch up with the impact of Yanxi, to Zuihou, the barrier is finally unable to withstand the impact of Yanxi's beam, in a crisp sound, slammed open, and the entire bronze gate once again returned to the silence and simplicity before.

"Is the formation broken!" Looking at the bronze gate that had broken through the barrier, Zhao Xiaoyi muttered, after the years of erosion, the formation could not withstand the impact of Yanxi after all, and it cracked.

And with the rupture of the formation, the bronze gate actually opened slowly by itself at this time, and the two bronze gates separated from the middle, gradually revealing a gap.

The gap opened became bigger and bigger, and the two bronze gates opened halfway to Zuihou, and the distance of five or six meters was enough for Zhao Xiaoyi to pass through.

"This is?" Looking through the open door, Zhao Xiaoyi's eyes were wide at this time, staring at the scene in the gate without blinking, and there was a more intense look of horror on his face.

"Thunder Domain!" Yanxi was also shocked, she folded her arms, looked inside the door with beautiful eyes, and exclaimed.

Inside the gate, it was an incomparably wide space, and there was no end in sight, and within the space, thunder and lightning with the thickness of an arm flickered violently in the air, like a spiritual snake, bursting into a crackling sound.

And under the space where countless thunder and lightning shined, it turned out to be a sea of thunder, and the endless thunder and lightning turned into torrents, like magma Lang tides, tumbling under the space, and above the tumbling Lang tide, the slightest violent thunder and lightning made people tremble.

"Minefield? This is a minefield. The frightened look on Zhao Xiaoyi's face did not disappear, his eyes were full of fanaticism, and then he cautiously stepped into the door.

The thunder domain is extremely vast, and the whole is a thunder sea, and the tumbling thunder and lightning torrent has no end in sight, only the violent aura emanates from it.

Zhao Xiaoyi has subtle thunder and lightning attributes in his body, so he is excited about this thunder domain, the power of thunder and lightning here, I don't know how many times more powerful it is than the thunder and lightning fury that becomes rainy outside, if these liliang can be used, I don't know how strong the combat power will be.

However, at this moment, Zhao Xiaoyi's complexion suddenly changed, because he clearly felt that the other dantian in his body was throbbing at this time.

This dantian is an independent dantian that he was born and opened up when he practiced the Great Thunder God Decision, for so long, there has never been any movement, and the dantian is also empty, I didn't expect it to throb here now, could it be the reason why the thunder and lightning here are too violent?

This second dantian was opened up by the Great Thunder God Decision, and the Great Thunder God Decision is an existence that grows by absorbing the five thunders, and these thunderbolts alone should not be able to cause the Great Thunder God Decision to throb!

"Yanxi, can you feel that there is something else in this thunder domain!" Zhao Xiaoyi turned his head to look at Yanxi and asked at this time.

"Something else?" Hearing this, Yan Xi frowned slightly and said, "Could it be that the Great Thunder God you cultivated at the beginning must have moved?"

The Great Thunder God Decision was obtained by Zhao Xiaoyi in the Chunyuan Immortal Pond at the beginning, and Yanxi naturally knew that to be able to make Zhao Xiaoyi say this, it should be that Zhao Xiaoyi had movement in his body.

Zhao Xiaoyi nodded, the throbbing just now was very clear, he definitely didn't feel wrong, "The Great Thunder God has never moved for so long, why is there here, could it be that the thunder and lightning here are more violent than outside?"

Just as the two of them were talking, above the thunder sea about two hundred meters in front of them, a thunderbolt the size of a water tank suddenly fell from mid-air, piercing into the thunder sea below like an optimus pillar.

And as the thunder and lightning the size of the water tank fell, Zhao Xiaoyi and Yanxi also followed closely and saw that in the thunder sea, where the thunder and lightning had just fallen, there was actually a white thunderbolt swimming in the thunder sea, like a dragon.

"What is this?" Looking at the swimming white thunder and lightning, Yan Xi's face changed suddenly, "Wind and thunder!"
