In the end, Xiao Yunkong had to choose to break through from his left.

But at the moment when the attack from the left fell on him, the spear of the Northern Wind had already turned into a stab and smashed into a slam on his body.

"Bang!"

"Click!"

With an obvious bone cracking sound, Xiao Yunkong's body suddenly spurted out a mouthful of blood, and then his body smashed towards the thunder sea with a slam.

At this moment, the purple lightning golden crystal beast above the thunder sea immediately manipulated the thunder and lightning to slash towards Xiao Yunkong.

"Boom!"

More than a dozen purple lightning golden crystal beasts manipulated thunder and lightning at the same time, and the consequences could be imagined.

Even if the Xiao family is famous for its thunder swordsmanship, it can't save Xiao Yunkong at this time.

The moment his body fell, more than a dozen thick thunder dragons snaked down and slashed towards him at the same time, and in an instant, Xiao Yunkong's body was immediately surrounded by countless lightning, and then a white light flashed.

As a result, Xiao Yunkong didn't even have time to scream, but he was scorched by the thunder.

Seeing this scene, the other Saint Monarchs all looked at each other in disdain, and then hurriedly flashed their figures and left here in the shortest possible time.

This person is really terrifying!

......

And after the others left, the North Wind didn't chase after it.

After fighting these Holy Monarchs, he probably knew his current strength.

Then, the Northern Wind raised his eyes to look at those purple lightning golden crystal beasts for half a quarter of an hour, and then immediately withdrew from the Thunder Sea.

After there was no one below, those purple lightning golden crystal beasts left the thunder sea and returned to the thunder pool.

After the purple lightning golden crystal beast disappeared, the Northern Immortal Long Wind returned to the bottom of the Thunder Sea and found the astral boundary in the next moment.

At this time, Murong Jiujiu also came out.

"Changfeng, are you okay?" Murong asked with concern for a long time.

Hearing this, Beiming Changfeng shook his head, and then said with a smile: "I'm fine, the heavenly thunder here is extremely good for refining the physical body, next, let's find a place to cultivate well." ”

Murong Jiu listened for a long time and immediately nodded.

Next, the two of them found a location not far from Lei Hai, laid out the formation and began to cultivate.

......

The main thing that the Northern Hell's Long Wind wants to refine is his own body, and he has been guiding the heavenly thunder towards his body at will.

Every time the thunder falls, the Northern Wind will become covered in blood, but soon the skin will recover.

In this way, just an hour later, the body of the Northern Underworld Changfeng was already covered with a thick layer of blood scabs.

As for Murong Jiujiu, what she wants to refine is her own spiritual power, so what she has to do is much more dangerous.

She wants to introduce the heavenly thunder into her spiritual consciousness sea, so that she can temper her spiritual power.

At first, Murong Jiujiu only cautiously introduced a heavenly thunderbolt the size of a baby's forearm into his spiritual consciousness sea.

After a loud "boom", a heavenly thunder immediately exploded in Murong Jiujiu's mind, making her feel dizzy with tinnitus.

But fortunately, her spiritual power has improved a lot, so after just a short moment of being swollen by the thunderous ears of this day, Murong has been used to it for a long time.

Immediately after, she used her spiritual power to fight with Tianlei.

And it turns out that the heavenly thunder here is indeed extremely beneficial to her refining her spiritual power, and she can feel that in this way, her spiritual power will become more and more condensed and stable.

So next, Murong Jiujiu directly introduced the Heavenly Thunder into his soul sea, and let it continue to scurry around in his soul sea until his own spiritual power consumed the power of the Heavenly Thunder, and then introduced the next Heavenly Dao.

......

After three months like this, Murong Jiujiu's spiritual consciousness sea has become more stable compared to the past, and the golden wheel in Murong Jiujiu's soul sea has also become more pure and profound.

Then there is the diffusion area of this golden wheel.

In the past, this golden wheel had expanded to two-thirds of the area of Murong Jiujiu's soul sea, but after being tempered by the heavenly thunder, the area of this golden wheel had actually shrunk a lot, and the distance between each circle of the golden wheel had also become much smaller.

This is not a bad thing, but a great thing.

This means that a greater possibility has emerged, maybe Murong Jiujiu, who could only have seventy laps of the Golden Wheel, may be able to have eighty laps or even the best ninety-nine rounds of the Golden Wheel after the tempering of the heavenly thunder!

And after Murong Jiu saw the changes in the golden wheel in his soul sea for a long time, he also felt a wave of joy in his heart.

Sure enough, it is not possible for her to blindly improve her spiritual power, even if she cultivates her spiritual power, she still needs to be tempered and experienced!

If she hadn't come here with Changfeng, she would have been using the medicinal herbs and pills given by Wei Wuji in the lotus pond to improve her spiritual power, how could she have tempered her spiritual power to such an extent like now?

You must know that when you are in the reincarnation realm, one more golden wheel in the soul sea means that you have more possibilities than others, and you have more unlimited potential!

......

And because the secret realm here is only open for one year at a time, Murong Jiujiu is thinking about the future.

So, when the Northern Darkness Changfeng woke up from meditation again, Murong Jiujiu couldn't help but say, "Changfeng, we have a limited amount of time here, so next, why don't we think about getting more Thunder Tribulation Liquid?"

The Thunder Tribulation Liquid is more effective in refining their physical and mental powers, and the safety factor is higher.

Hearing Murong Jiujiu's words, Beiyin Changfeng immediately nodded and said, "You're right, it just so happens that I have already obtained the thunder and dark iron lock of Xiao Yunkong, and next, let's think of killing some of the purple electric golden crystal beasts in the thunder pool!"

The Thunder Gold Heart of the Purple Electric Golden Crystal Beast and the single horn on its head are extremely beneficial to them, and if they can take more, they will naturally have to take more.

Murong Jiu listened for a long time and immediately nodded.

Next, the two returned to the Thunder Sea, and then cooperated.

First, the Northern Darkness Changfeng quickly extracted more than a dozen drops of Thunder Tribulation Liquid and quickly cut it off by Murong Jiujiu with his spiritual power, and then after the furious Purple Electric Golden Crystal Beast appeared, the Northern Darkness Changfeng used the Spatial Secret Technique to transfer one of the Purple Electric Golden Crystal Beasts thousands of miles away.

After this somewhat confused Purple Lightning Golden Crystal Beast was transferred, the Northern Darkness Changfeng immediately restrained it with the Thunder Binding Iron Lock, and then Murong Jiujiu blocked the space of ten miles nearby, so as not to attract the attention of other monks, and came over to take advantage of the fire to rob.

......

And when this purple electric golden crystal beast reacted that it was tied up, it suddenly roared angrily, and there were bursts of thunder on its body, trying to break free from the thunder black iron lock.

Fortunately, this lock is reliable, and this purple electric golden crystal beast can't break free for a while, so next, Murong Jiujiu and Beiyin Changfeng are working together, one uses spiritual power to chop the single horn of the purple electric golden crystal beast, and the other uses a long sword to split the body of the purple electric golden crystal beast.
