Lin Ze deliberately changed the topic, clipped the Yunlei Stone to his fingertips, and asked, "I see that you are expelling the impurities inside, what experience do you have to share?"

Speaking of this, Gong Lingye sighed and said, "Although with the help of that purple thunder and lightning, some of the impurities in it have been removed, but it is still too slow, and it is estimated that it will take about a year for the first layer of prohibition to appear." Coupled with the time of the refining ban, it will take at least a year and a half. Unless ......"

"Unless what?" Lin Ze asked, and then he understood, if he wanted to speed up, he was afraid that he would have to do it like last time.

Thinking of this, he couldn't help but shudder, he was already very lucky to be able to survive last time, and he didn't want to experience it again.

Lin Ze shook his head and said, "No, that kind of power is not something that can be fought against by manpower, it is a fluke to survive this time, you don't want to try." ”

One of the most important reasons why he was able to survive this time was because of the help of the Chaos Creation Map, who knows if it will help next time?

"Well, that's just a step-by-step grind to remove the impurities in it. Gong Lingye said dejectedly.

Lin Ze didn't worry too much, and after asking Gong Lingye in detail about the method of refining impurities, he came to the corner of the stone house alone and began to try.

When his true qi was almost exhausted, he stood up, and the situation was indeed as Gong Lingye said, the speed of expelling impurities was very slow.

After pondering for a moment, Lin Ze looked outside and said, "I'll try it outside." ”

As he spoke, he walked past Gong Lingye and came outside.

When the stone door was pushed open, there was a roar in my ears again, thunder and lightning danced wildly in the air, and the ground was like a wave of thunder, surging endlessly.

Sitting cross-legged on the ground, his whole body was instantly enveloped by thunder and lightning, and one after another thunderbolts shot out from the ground, hitting his body, and shaking his body.

Although these thunderbolts are dense and powerful, they are still far from the purple thunderbolts.

The wounds on Lin Ze's bare skin exploded one after another, and then they were quickly repaired, and he turned a blind eye to these, and held the child's fist-sized thunder stone in the palm of his hand.

The divine consciousness slowly spread out, and while feeling the power of thunder and lightning around him, he refined the power that invaded his body.

Time flew by again, and soon a day passed, and then another three days.

Lin Ze has been sitting outside the door, Gong Ling has come to see it several times in the night, but he can't see anything famous, so he simply doesn't pay attention to this side anymore, and is busy with his own affairs.

At this moment, the thunder and lightning around Lin Ze seemed to be pulled by an invisible force, gathered above his head, and then slammed down, just on the thunder stone held in his palm.

With a loud bang, the Yunlei Stone was violently smashed, and Lin Ze's palms were also split and bloody, but there was a smile on his face.

"It works!"

These days, he's been trying to use his divine sense to pull the thunder and lightning around him, so that they can gather together, so that it will be more powerful.

Carefully observe the Yun Thunder Stone in the palm of his hand, after this thunder and lightning quenching, the impurities in it were really driven away a little, and the speed was ten times faster than slowly grinding with True Qi.

In the following time, Lin Ze followed this method and continuously used thunder and lightning to quench the thunder stone.

A month later, Lin Ze stopped again, and the further he went, the slower the effect of this method became, which made it necessary to pull more thunder and lightning over; after three or four times, he had to stop and rest, otherwise he would definitely be dizzy and unconscious because of the huge consumption of divine consciousness.

Standing up and returning to the house, Gong Lingye also opened his eyes, his progress during this time was even slower, and his speed was less than one-tenth of Lin Ze's.

"You wait here, I'll continue to go deeper into the Thunder Valley to try, the thunder and lightning power here is still too weak, and the speed is slower. Lin Ze said directly.

Gong Lingye knew that Lin Ze used his divine sense to pull thunder and lightning to quench the Thunder Stone, and he only had envy and did not stop him.

Bidding farewell to Gong Lingye, Lin Ze began to march towards the depths of Thunder Valley, and the thunder and lightning around him were still violent, hitting his body, exploding clumps of blood.

However, the situation is much better than when he first fled to the small stone house.

First, it is because his cultivation has been greatly improved, and secondly, his divine sense can be released, plus his perception of the amount of thunder and electricity around him for more than a month.

The thunder and lightning that hit him, he could pull a large part of it into the thunder stone in his hand, so as to avoid himself from being bombarded by too much thunder and lightning and being hit hard.

When he came to a depth of two hundred and twenty zhang, he stopped, chose a place, and began to refine the Yunlei Stone.

This place is much better than in front of the small stone house, and the impurities contained in the thunder stone have been worn away little by little.

Half a month later, he stood up again and entered the range of two hundred and thirty zhang.

A month later, he continued to go deeper, stopping at a position of about two hundred and forty zhang.

The thunder stone in his hand changed from the size of a child's fist to the size of an egg, and tiny cyan markings began to appear on the surface.

After a month and a half, the surface of the stone began to become smooth and flat, from an irregular shape to a regular oval shape, and the volume began to shrink further.

Two months later, when Lin Ze could no longer grind even the slightest bit of the impurities in the Yunlei Stone, his divine sense was entangled in the Yunlei Stone, and he finally sensed a faint layer of natural prohibition in it.

"The first layer of prohibition has finally appeared!" Lin Ze exhaled a long breath of turbidity, and his whole person relaxed, and a wave of exhaustion swept over him instantly.

Forcibly cheered up, retreated from the position of two hundred and forty zhang to about two hundred and twenty zhang, and immediately sat on the ground, and began to refine this layer of prohibition, leaving him with little time left.

Although the collapse of the small stone house will not cause much trouble to him now, but for Gong Lingye, it will be a catastrophe, and he can't help if he wants to.

Another month later, with the help of the thunder and lightning power here, the first layer of the Thunder Stone was completely refined, and the Thunder Stone also turned into a small pale cyan ball, only the size of a pigeon's egg.

When this layer of prohibition was refined, there was a feeling of mental connection between him and the Yun Lei Stone, as long as his mind moved, without the help of his divine sense, the Yun Lei Stone could pull the surrounding thunder and lightning and suck it all inside, without causing any harm to Lin Ze.

"From now on, I'll call you Yun Lei Zhu. ”

Lin Ze played with the Yun Lei Bead, full of joy, this was his first magic weapon, although the grade was very low, it also made him feel a sense of accomplishment in his heart.

The Yun Thunder Bead had been refined, and Lin Ze began to return.
