Tian Qing was very depressed by the explosion of this mysterious yuan stone, but he was helpless. He looked at the powder on the ground and thought about it for a while, but he couldn't figure it out.

He had to take out the piece of Shenhai Xuanlei Essence Iron that Jin didn't exchange for him, and began to study it.

Tian Qing held this piece of fine iron in his hand, feeling the power of thunder and lightning of this gadget. After a while, Tian Qing groaned slightly, and suddenly opened his mouth and spit lightly. A three-inch-long light blue sword swam out of its mouth, and the small sword was the Yuan Spirit Sword Embryo that Tian Qing had cultivated for nearly thirty years. This thing was originally made with the Lan Yuan Jing in the storage bag of the barbarians in the Jiedan period, and most of the refining procedures were made with the help of Li Yunhan, and it has been cultivated until now, although it is also a good treasure among ordinary monks in the foundation building period, but compared to the Infinite Thunder Ring, both the power and lethality are much worse, and Tian Qing has never used it.

But now that you have this Xuanlei Essence Iron, you can add the Essence Iron to the small sword to increase the power of the small sword.

However, the refining method was quite complicated, Tian Qing didn't dare to do it rashly for a while, and controlled the little sword to fly around him a few times, Tian Qing opened his mouth and took the little sword back into the dantian.

Staring at the Xuanlei Essence Iron on the ground, a bold idea suddenly appeared in Tian Qing's heart.

This thought appeared, and a trace of excitement flashed on Tian Qing's face.

After a while, a high-grade homemade thunder spirit stone suddenly appeared in Tian Qing's hand, and began to absorb the spiritual power inside, and the other hand was not idle, and the palm thunder slashed towards the small funnel.

Of course, Tian Qing didn't want to waste the few thunder spirit stones on his body, but now that time was pressing, this idea was novel and bold, and full of unknown temptations, Tian Qing had to do so.

A quarter of an hour later, all the spiritual power in a thunder spirit stone was exhausted, and the small funnel fed in a flash, and the runes on it rose into the air, showing signs of spewing thin white light.

Tian Qing didn't say a word, and gently released a stream of spiritual power, putting the Xuanlei Essence Iron under the small funnel.

The white light began to gush out, hitting the piece of Xuanlei Essence Iron.

Sure enough, Tian Qing was not disappointed, the white light came into contact with the artistic conception of Xuanlei Essence Iron, and Xuanlei Essence Iron was like a bottomless pit, sucking all the white light into it, and after the torrent generated by the small funnel was over, Tian Qing looked at this piece of Xuanlei Essence Iron again.

The original Xuanlei Essence Iron only flashed slightly, and there was a small electric flame flickering on it, while the Xuanlei Essence Iron that absorbed a small funnel energy torrent increased the dazzling degree of light and electric fire by one percent.

Impressively, the age of this piece of Xuanlei Refined Iron has increased from 8,000 to 9,000 years.

Seeing this, Tian Qing was overjoyed, and without hesitation, he took out a high-grade spirit stone again, and began the long process of cultivating Xuanlei Essence Iron.

Half a day later, nearly a dozen high-grade spirit stones had appeared on the ground, and the year of Xuanlei Essence Iron had grown to an exaggerated 20,000 years.

The current Xuanlei Essence Iron has floated in the air by itself without Tian Qing's control, floating up and down slightly in front of Tian Qing, the light on the Refined Iron is deep and restrained, not like the flash of the Ten Thousand Years without any consideration, it looks extremely mysterious.

Tian Qing was overjoyed, this shows that this piece of fine iron has already appeared with basic spirituality, but the spiritual time of appearance is too short, and this fine iron does not have too high autonomy.

It was still early to make an appointment with Jin Buyi, so Tian Qing decided to see if he could cultivate this piece of fine iron to a higher spirituality.

With a little pain, he took out all the high-grade spirit stones, counted more than twenty pieces, Tian Qing grabbed one, and began the endless process of cultivating spiritual objects again.

Two days passed quickly, and there were only three high-grade spirit stones in front of Tian Qing, and there was a huge change in the Xuanlei Essence Iron.

At this moment, the Xuanlei Essence Iron can't help but have no trace of light and ignition flickering on it, and if it is placed on the ground, it is no different from an ordinary stone, if it is not sensitive to the spiritual power of the thunder attribute or has never seen such a year of Xuanlei Essence Iron, even if he uses his divine sense to sweep this Essence Iron, he will also treat it as a stone.

Seeing this strange change in Xuanlei Jingtie, Tian Qing was not only not disappointed, but ecstatic.

It is a stone-like heaven and earth spirit creature that has developed the most basic spiritual state! This little thing has learned to disguise itself.

Tian Qing stared at the Xuanlei Jingtie on the ground, and with a push of spiritual power in his hand, a small fireball appeared on his fingertips. He bounced the fireball at the fine iron on the ground.

I saw that the moment the fireball immediately attacked Jingtie, the Jingtie seemed to have been kicked by something, and rolled on the spot a few times, narrowly avoiding the attack of the fireball, and then lay on the ground motionless and pretending to be as if nothing had happened.

Tian Qing smiled, and ten fireballs instantly appeared on the tips of his fingers, throwing them out in all directions of the Xuanlei Essence Iron.

The fireball had already sealed all the retreats of Xuanlei Jingtie, and even if it wanted to, it couldn't escape.

But Xuanlei Jingtie didn't move at all this time, allowing the fireball to hit its body.

There was a loud bang, and the stone ground where Xuanlei Jingtie was located was already pitted, and white smoke was still emitting from time to time, but it was unharmed at all, and it was still lying on the ground honestly and not moving.

Why didn't you hide this time? Tian Qing began to question in his heart, but the next moment, his face suddenly changed drastically.

"Boom!" suddenly there was a thunderclap outside the cave.

Tian Qing wrapped the fine iron on the ground, flew out of the cave, and came to an open area.

I saw that the sky had become inky and filled with countless thunderclouds. Bursts of low roars came from the thunderclouds, looking like heavy rain was coming.

"Thunder Tribulation!"

Tian Qing's face suddenly became strange, and he threw the Xuanlei Essence Iron in his hand to the ground again, and then a large handful of small flags appeared in his hand, and the thunder flashed on his body, and he flew to the edge of the island in the blink of an eye, and began to plant the formation flags along this deserted island within a radius of three or four miles.

This formation was obtained from Ma Zhenren, and it was the mist formation covered by Zeyu Mountain when Ma Zhenren crossed the tribulation. This formation was originally not so big, but with Tian Qing's current formation level, this basic psychedelic formation can still be improved at hand.

The reason why this is like this is that Tian Qing never expected that after this Xuanlei Essence Iron turned into a spiritual object of heaven and earth, he would actually have to cross the heavenly tribulation!

Tian Qing was very depressed at the same time, he could only set up a formation to prevent the vision of heaven and earth formed by this heavenly tribulation from attracting other monks, he was not like attracting a large group of people to scramble for the things that he had managed to get out.

If he attracts a monk who is not a monk, he Tian Qing will not be able to eat and leave!

Also, this deserted island is only about a thousand miles away from Qunxing Island, and this formation may not be able to completely cover the vision of heaven and earth, attracting a small number of monks that Tian Qing feels can handle, and he can only fight with them.
