At this time, the clouds in the sky were already dark and breathtaking, and a large amount of electric light flashed in them, making a buzzing sound.

"Hahaha, haha, Heavenly Tribulation, come on! I have been cultivating for decades, and this is the day I have been waiting for!"

When Su Yichen and the three of them were observing the clouds, a burst of arrogant laughter came from the back mountain, and at the same time, an old man in a Taoist robe flew into the air.

The clouds in the sky seemed to have heard Bai Yuan's words, and as soon as his words fell, a thumb-thick thunderbolt slashed down from the air.

Although the thunder and lightning are only as thick as a thumb, but the power is very great, Bai Yuan in mid-air did not dare to be careless, and at the same time as the thunder and lightning fell, his hands supported a light curtain to resist the thunder tribulation.

"Haha, it's nothing more than that!" Bai Yuan laughed after the lightning cleared.

After hearing this, the Black Emperor said disdainfully: "What kind of strength is it, it's just the most ordinary Heavenly Tribulation!"

Su Yichen's heart moved after hearing this, and asked, "Are there many kinds of heavenly tribulations?"

The Black Emperor glanced at him, raised his head and said: "Of course, like this old horseman's Heavenly Tribulation, it is just the most ordinary Three Thunder Tribulation, and on top of this, there are six Thunder Tribulations, nine Thunder Tribulations, and even Taiyi Thunder Tribulations, as well as some legendary Heavenly Tribulations,"

After hearing this, Su Yichen and the three of them couldn't calm down for a long time, and they couldn't imagine that a catastrophe was so different.

At this time, in the clouds in the air, the second thunderbolt had already been brewed, and then a fist-thick thunderbolt roared towards Bai Yuan, and for a while, the thunder and lightning were filled in the air, and the electric light flickered.

Bai Yuan looked at the second thunder tribulation that came from the roar, he didn't dare to be careless, his internal cultivation was running to the extreme, and his hands supported a more brilliant light curtain.

"Zizizi~!"

Thunder struck the light curtain with a sizzling sound.

After a few breaths, the power of the Thunder Tribulation did not weaken in the slightest, but the light curtain held up by Bai Yuan dimmed a lot.

In the end, the light curtain shattered, and the remaining power of the Thunder Tribulation all fell on Bai Yuan's body.

Bai Yuan's body suddenly arced, blood stains appeared on the corners of his mouth, and the qi of the whole person was also a little weakened, despite this, he still survived the second thunder tribulation safely.

"This is the second thunder tribulation, this old horseman has barely survived, if there is no other preparation, the third thunder tribulation, he will definitely die!" said the Black Emperor as he looked at the dark clouds in the sky.

At this time, from the clouds in the air, there was a rumbling sound of thunder, looking at the clouds, Su Yichen felt a sense of oppression, which made him feel uncomfortable.

Zhao Yun and Cheng Biting Jin are no better, the three of them are still like this, it is conceivable that Bai Yuan, who is crossing the tribulation, is locked by the thunder tribulation at this time, and the oppressive power he bears is huge.

"Black Emperor, breaking through the same realm, is everyone's thunder tribulation the same?" Zhao Yun frowned and looked at the tribulation clouds in the air and frowned and asked.

After hearing this, the Black Emperor stood upright, paced back and forth, shook his head and said: "How can it be the same, the strength of the thunder tribulation is determined by personal talent, and other factors, some people crossed the tribulation for the first time, there was a Taiyi thunder tribulation, when people, like this kind of people are talented, as long as they do not fall, they are destined to dominate the world, become holy and be an ancestor, don't think about it, the qualifications are too poor, according to the emperor's observation, you are also the six thunder tribulation!"

"Then what kind of thunder tribulation was your first tribulation?" asked Cheng Yanjin.

When the Black Emperor heard this, he instantly stopped walking

Su Yichen and Zhao Yun also looked at him curiously, and the two of them clearly saw the Black Emperor's dog mouth twitch a few times.

After a pair of dog eyes turned around a few times, the two legs in front of him hugged his chest like a human being, and said proudly: "Needless to say, with the talent of this emperor, the first heavenly tribulation is the Taiyi Thunder Tribulation!"

When Su Yichen saw the Black Emperor like this, he knew that he was lying, and said angrily: "The most powerful thunder tribulation you know, isn't it the Taiyi Thunder Tribulation!"

"What do you mean?"

The Black Emperor was puzzled, and Zhao Yun on the side didn't explain anything with a smile.

"Hey, lord, what do you mean?"

The Black Emperor asked, but Su Yichen still ignored him.

"Boom~!"

When the Black Emperor just reacted, a thunderbolt with the thickness of a bowl mouth flashed out from the clouds, and its power was several times stronger than the second one!

Bai Yuan looked at the third thunderstorm, his face became a little ugly, and then he gritted his teeth, turned his right hand, and a bronze ancient mirror appeared in his hand, and with a raise of his right hand, the bronze ancient mirror flew into the air, and the wind rose, and the ancient mirror that was originally the size of a palm became more than a zhang long in the blink of an eye, protecting Bai Yuan.

After the bronze ancient mirror stopped getting bigger, the third thunderstorm also came in an instant, carrying the power of destruction that could destroy everything, and crashed into the ancient mirror.

But to the surprise of Su Yichen and the others, the thunder crashed on the ancient mirror, like a stone sinking into the sea, and it was absorbed by the ancient mirror without making a sound.

Each thunderstorm lasted for nearly thirty seconds, and now it was like a waterfall, falling from the sky, and then absorbed by the ancient mirror.

"Do you know what kind of magic weapon this bronze mirror is? it can even absorb the Heavenly Tribulation!"

Su Yichen looked at the bronze ancient mirror above Bai Yuan's head, his eyes were hot.

"It's just a spiritual artifact, it's not a big deal, according to the Emperor's observation, the limit of this mirror is almost reached!" the Black Emperor said.

As soon as his words fell, a slight crack appeared on the bronze ancient mirror, and after Bai Yuan saw it, his face changed, and he couldn't help but worry in his heart.

After a few more breaths, the crack on the bronze mirror was clearly visible, and at this time, the size of the thunderbolt was only the size of a baby's arm.

After a few more seconds, when the thunderbolt was only the size of a thumb, the energy that the bronze ancient mirror could absorb also reached the extreme, and finally it fell apart with a bang.

Although Bai Yuan felt sorry for the destruction of his magic weapon, he couldn't allow him to think too much at this time, and if he lost the resistance of the magic weapon, he could only rely on himself to resist the rest of the thunder.

didn't dare to hesitate, propped up the light curtain with both hands, and resisted the thunder with difficulty.

At the time of the second thunderstorm, he had already been injured, and at this time, in the face of the thunderstorm that was only as thick as a thumb, after resisting a few breaths, the light curtain he held up shattered, and the remaining chopstick-thick thunderbolt fell directly on him.

As soon as the thunderbolt landed on Bai Yuan, he spat out several mouthfuls of blood, and his hair stood on end.

After two or three breaths, the thunderstorm completely dissipated, and Bai Yuan's qi was already very weak, but he still gritted his teeth and insisted on flying in the air, looking at the clouds in the air with a look of longing.

"Isn't the tribulation over, what are you waiting for this old guy?" asked Cheng Yanjin, scratching his head.
