The cloud and mist formation arranged by Tian Qing soon began to work, and the clouds of fog spread to the entire island, Tian Qing looked at the dark clouds in the sky, which were almost also covered by the clouds and mist, and the clouds and mist of the formation were connected, if you didn't get close to the island and look carefully, it would be difficult to find the clues, Tian Qing was relieved.

He flew to the edge of the formation and spread his divine consciousness completely, covering the entire deserted island.

After a cup of tea, the dark clouds in the sky have thundered, and the thunder catastrophe is coming!

Tian Qing's eyes flashed with a hint of excitement, and he was looking forward to what shape the Xuanlei Essence Iron could turn into. You must know that the distinction between heaven and earth and spiritual objects is very important, that is, transformation.

If the spirit object turns into a human form, it is the most powerful, and it can directly cultivate immortals on its own, and it is possible to cultivate to a very high level, and the lifespan of heaven and earth spiritual objects is generally much longer than that of human monks, as long as there are no accidents on the way to cultivating immortals, they can often be cultivated to a very high level.

Compared to turning into a human form, a little worse transformation is turning into a beast. Beasts also have some spiritual intelligence, and they can cultivate in places with abundant spiritual power and spiritual power, but their intelligence is not as high as that of spiritual objects that have turned into human forms, and they are relatively easy to be caught by monks.

There are some heaven and earth spirits that incarnate and do not need to go through the heavenly tribulation. But the living creatures they form are generally intellectually inferior, and can only survive on some instincts. The heaven and earth spirit creatures that have experienced the Heavenly Tribulation will turn into animals with higher intelligence.

Of course, this is also related to the properties and materials of the heaven and earth spirit objects themselves. Like an ordinary Ganoderma lucidum, it happens to live in an environment with extremely abundant spiritual power, and it will become a spiritual creature of heaven and earth after growing for 10,000 years, but they often turn into insects. If a precious and incomparably colorful bauhinia transforms, it will turn into a bird or a small beast, which will be much more powerful than an insect.

Tian Qing had some expectations, the heaven and earth spiritual creatures that had experienced the Heavenly Tribulation could at least turn into small beasts.

However, the Heavenly Tribulation is a Heavenly Tribulation after all, and it is also the tomb of most heaven and earth spiritual objects.

The dark clouds became denser and denser, and finally, the first thunderstorm fell!

A golden lightning bolt of incomparably bright, about the thickness of a small arm, accompanied by a crisp and loud thunder, slashed straight down at the Xuanlei Essence Iron below. The black gadget also felt the danger, and finally unlike an ordinary stone, it suddenly burst out of a dazzling dark blue light, forming a dark blue electric light, which collided with the golden thunder in the sky.

"Click!" A huge explosion spread throughout the island, and immediately, the fire was blazing, and the blazing heat spread around the Xuanlei Essence Iron, melting all the stones around the Xuanlei Essence Iron and turning it into red magma.

Tian Qing couldn't help but sigh slightly, this attack of the Heavenly Tribulation and the counterattack of the Xuanlei Essence Iron were at least equivalent to the full force of the Qi Cultivation Great Perfection Cultivator.

However, the catastrophe was not over, and one after another slashed towards the Xuanlei Essence Iron that was hanging more than three feet above the magma.

Successive explosions continued to be heard, and the trees within 100 meters of the center of the explosion were uprooted, a scene after the explosion of a huge bomb.

Finally, the first round of the Tribulation is over.

Xuanlei Jingtie was now like a small blue sun, constantly 'crackling' and flashing with electric light around it, obviously, the first round of heavenly thunder did not cause any actual damage to it.

After a few breaths, the dark clouds in the sky churned again, and it was still golden thunder and lightning, only this time, the thickness of the thunder and lightning was almost as thick as an adult's thigh.

The thigh-thick thunderbolt slashed downward with an astonishing momentum. Seeing this, Xuanlei Essence Iron did not release thunder and lightning like the first round of Heavenly Tribulation, but converged the thunder light around him, and the original dark blue Xuanlei Essence Iron instantly turned into dark purple, motionless and directly let the Heavenly Tribulation slash to it.

The Heavenly Tribulation hit the Xuanlei Essence Iron, and the Thunder Essence Iron was instantly split into the air, falling into the magma and disappearing.

Seeing this, Tian Qing did not show any surprise, but stared at the thundercloud tightly. He had already used his divine sense to find out that the Xuanlei Jingtie had not been harmed in the slightest.

After all, this was a forty or fifty-thousand-year-old piece of Xuanlei Essence Iron, and ordinary Jiedan monks couldn't shatter it with a single blow, let alone this golden thunder tribulation that only had the strength of the initial attack of foundation building.

In a moment, thunder light appeared in the magma, and the Xuanlei Essence Iron slowly floated out of it.

One after another, soon, more than ten thunder tribulation strikes hit the Xuanlei Essence Iron, each time the Xuanlei Essence Iron was deeply hit into the magma, and the Xuanlei Essence Iron flew out by itself, continuing to welcome the baptism of the Heavenly Thunder.

In the third round, the Thunder Tribulation had reached the attack level of the late stage of foundation building, and Tian Qing's eyelids jumped straight when he saw it, but Xuan Lei Jingtie still took all the attacks without hindrance.

After the third round of the tribulation ended, Tian Qing began to be calm.

The clouds are still gathering and feeling thicker and thicker. It seems that there is still infinite energy that has not been released from it. It seems that this Heavenly Tribulation is going to attack at least the five rounds of Xuanlei Jingtie, which is more than Ma Zhenren's Tribulation!

That's not a good thing.

The Xuanlei Essence Iron was still faintly suspended, and the purple light on his body had also condensed to the extreme.

The fourth round of Heavenly Tribulation descended, a total of five realms, reaching the attack level of the Great Perfection of the Foundation Building Period, and the aftermath of the attack had already melted the area of more than thirty zhang near the Xuanlei Essence Iron into liquid.

When the first Heavenly Tribulation of the fifth round fell, Tian Qing no longer dared to stay in place, for fear that the Thunder Tribulation would smash the Xuanlei Essence Iron, and then he would be busy in vain. He flew to a distance of about a hundred zhang from Xuanlei Jingtie, holding a small funnel in his hand, ready to support at any time.

Suddenly, the fifth round of Heavenly Tribulation reached the attack level of the early stage cultivators.

"Boom!" "Boom!" "Boom!"

One after another, the golden thunder tribulation of the thickness of the big fat man's waist pole slashed into this dark purple stone, splitting the Xuanlei Essence Iron flying everywhere, but no matter where it flew, the golden lightning hit it with great accuracy and sent it flying again.

Soon, half of the island was in flames, and the beasts and birds on the island panicked and ran around.

However, the catastrophe is not over.

As the clouds thickened, the sixth round of the Tribulation descended.
