The dark red clouds seemed to be just above their heads, giving people a powerful oppression, and then the entire sky turned dark red, whirring and spinning like a whirlpool, and purple electric snakes around them were constantly looming.

"This is stronger than the ordinary Immortal Mansion Tribulation Thunder. Hua Chang's face was solemn, because they were afraid of disturbing Su Dong's tribulation, they could only transmit the sound.

"Yes, it's too strong, there are a total of three thunder tribulations in the Xianfu Tribulation, but I'm afraid that this first heavenly thunder is similar to the second heavenly thunder of the ordinary Xianfu Tribulation. Hua Dong also nodded heavily.

Extrapolating it like this......

The second heavenly thunder can be compared to the third heavenly thunder, as for the third ......

The expressions of several people sank.

Snort.

The whirlpool spun faster and faster, and all the aura of heaven and earth within a radius of a hundred miles was chaotic, and purple electric snakes meandered in the whirlpool, and even the calamity clouds gradually merged, and finally turned into a huge purple calamity cloud.

Purple!

The clouds and thunder are all purple.

Su Dong's face was also extremely heavy, the previous Water Moon Tribulation, including his previous life, the Cloud Tribulation and Thunder were all blood red, which was also a major feature of the Xianfu Tribulation, but this time it was purple, rich purple.

Rumble!

There was a huge roar, and a purple heavenly thunder turned into a 'purple divine dragon' and slashed towards Su Dong in the center of the circle, and there were a total of three heavenly thunders in the Immortal Mansion Tribulation, one stronger than the other, but just this first one, Su Dong felt great power.

"Condensation. Su Dong shouted loudly, and immediately activated the Tiangang Defense Formation, and the light at the edge of the formation was whirring and flowing, and then directly formed a gas cover, with the formation as the edge of the milky white air cover, which firmly protected Su Dong.

The Tiangang defense formation contains the power of gossip, and the power of the five elements of the ancient dragon clan, the defense is already amazing, coupled with the nourishment of the aura around this Gufan Mountain Range for nearly a month, this defense is much greater than imagined.

"Your Tiangang Defense Array's defense is bigger than you think. Hua Chang's eyes lit up slightly. Standing outside the formation, he could naturally feel the power of the Tiangang defensive array, which was faintly comparable to the second-level formation.

"Yes. Hua Dong nodded, he also felt it, and knew the reason after a little thought.

Although the Tiangang Defensive Array is a first-level defensive formation, why is it so profound, what he used a month ago, it still exists now, and this month, the aura of the surrounding heaven and earth has been pouring in continuously, which is equivalent to absorbing the aura for a whole month, and the power is naturally greater than imagined.

"The defensive power of the second-level formation...... It should be able to successfully block the first two thunderbolts. Hua Dong said slowly.

While a few people were talking, the purple heavenly thunder also slammed into the milky white air cover, and in the Tiangang defense array, the milky white aura immediately flowed eagerly, and the milky white air cover outside also trembled, but it was the first heavenly thunder that was blocked.

"Sure enough, the Tiangang Defensive Array is completely comparable to the defensive power of the second-level defensive array. Hua Dong's eyes lit up......

The purple clouds were constantly rolling, and the powerful coercion made Su Dong feel frightened, this second heavenly thunder ...... It turned out to be similar to the third heavenly thunder during the Water Moon Tribulation.

It's horrible!

"Drink. Su Dong shouted.

The golden light on the surface of the body was immediately released, it was the power of the Immortal Saint Body, with the Immortal Mansion Divine Body, Su Dong's whole person was golden, like an ancient god and Buddha, and at the same time, the left hand was detached from the mortal spirit sword, the right hand was detached from the mortal spirit sword, and the moonlight also lit up under his feet.

At this critical juncture, Su Dong used all his means.

Rumble!

Another purple thunder thundered down, this thunder was obviously much thicker than the first one, and even the purple thunder light was much thicker, snort, the purple thunder thunder slammed into the milky white air shield with a mysterious force.

Suddenly, the milky white air shield trembled violently like the surface of the water, and many forces such as the power of the gossip and the power of the five elements in the formation also continued to offset the power of the heavenly thunder.

But the power of the second heavenly thunder was too great, even if this milky white gas shield contained a variety of powers, it could not be resisted at this moment, and the energy of the shield was rapidly weakening.

"Not good. Su Dong's face changed.

Click.

Hearing only a cracking sound, the formation shield suddenly collapsed, and at the same time, the power of the gossip in the formation, the power of the five elements and other forces also dissipated, and the Tiangang defense array was considered useless since then, but the second heavenly thunder carried the residual energy and smashed down, and it hit Su Dong directly.

"Break it for me. Su Dong jumped ten meters high,

The left hand is detached from the mortal spirit sword, and the right hand is detached from the mortal spirit sword, the sword light and sword light flashed again and again, and even the surrounding space began to vibrate. The spirit sword turned into a blood-red sword light, and the spirit sword unleashed the Nine Heavens Wind Cloud Sword Technique, and fifty sword lights moved with the spirit sword.

Snort!

The sword light and sword light completely fused together, and immediately the light was great, and the void trembled and slashed out.

Rumble!

Su Dong's swords merged, and they all slashed on the heavenly thunder, the heavenly thunder was hundreds of zhang long, Su Dong looked extremely small under this heavenly thunder, but he slashed out with a sword, and the second heavenly thunder suddenly lost its light, and the heavenly energy inside also dissipated rapidly, and then the second heavenly thunder energy was also exhausted.

"Whew. Su Dong exhaled, and his face and body were all scorched, which was caused by the Heavenly Dao energy.

This is too difficult for him, fortunately, the second Heavenly Thunder was offset by more than half of the formation power before, otherwise it would really be suspended. There will be a period of brewing time between the second and third heavenly thunders, and Hua Chang and the others outside the formation are all staring at Su Dong.

"I'm fine, don't worry. Su shook his head and sat down cross-legged, the Immortal Fan Holy Body immediately opened, and the power of the divine body on the surface of the body also emerged, and the golden luster of the Dao appeared, repairing Su Dong's injuries with all his might.

"This is the second thunderbolt. Hua Chang's voice reminded solemnly.

"The second Heavenly Thunder is so powerful, then the third ......" Hua Dong's brows were also furrowed.

"There are so many treasures in the ancient dragon clan, I can't die even if I want to, don't worry. Su Dong smiled.

But no one laughed, there were many treasure pills of the Gu Long clan, but in case Su Dong died directly under this third heavenly thunder...... When a person dies, no matter how powerful and miraculous the elixir is, it can't be saved.

"It's a pity. You are a mortal monk, and you can't use the fairy baby. "Hwadong is helpless.

He had always thought that the immortal mansion was easy to cross, and he could get through it by throwing a few immortal magic weapons, but now it seems that he was very wrong, the power of the Heavenly Dao has always been fair and rigorous, and it has long been stipulated that the immortal monks cannot use the immortal magic weapons!!

The top of Gufan Mountain, above the sky.

The clouds tumbled again, and the color of the clouds changed from purple to dark purple, the whole sky was completely black, only the purple light could be seen, and even the sky, the purple clouds were slowly falling, as if they were going to press towards the Gufan Mountains, and the surrounding space made a clicking and squeezing sound under the purple clouds.

Heaviness!

Suffocate!

Outside the formation, Hua Chang and the others' faces sank, including Su Dong in the formation circle, they also stood up, their eyes staring at the falling purple tribulation cloud.

"Are you trying to kill me directly?" Su Dong's face sank like water.
