After three days, Yun Yi also had to avoid the power of these yin thunders, and left the sea of thunder waterfalls formed by the dark thunder.

He stopped not far from the sea of thunder and began to slowly realize the power of these thunderbolts.

At this time, he was a little weak-hearted, if he used the Dark Thunder Refining Body this time, without the protection of the system, then the excess power of the Dark Thunder would have no place to transfer, would it blow him up into powder?

Yun Yi thought about it again and again, and came up with a solution, he took out twelve small war halberds, surrounded a circle in front of him, and then began to hit the small war halberds with the Thunder Immortal Technique, so that they could adapt to absorbing the power of the thunder.

This process was extremely slow, and after more than ten days, these small halberds finally adapted to the thunder and began to absorb and store the power of the thunder.

Yun Yi then walked towards the Sea of Thunder again, and after the spread of these days, the Sea of Thunder became more and more violent.

More and more of the power of the Dark Thunder has nowhere to go, and it has been spreading to the depths of the ground of the Ten Thousand Ghost Caves, assimilating some old ghosts hiding in the depths of the earth into the Dark Thunder.

Yun Yi came to the edge of the Sea of Thunder, put the small halberd down beside him, and then activated the Thunder Refining Method, and tentatively took a trace of the thunder of the Dark Sea.

"Boom!"

There was a muffled sound, and it was inconspicuous in this sea of thunder and thunder, but Yun Yi had been blown up by this trace of thunder.

Yun Yi was terrified in his heart, and he forcibly suppressed the fear in his heart, and constantly operated the thunder refining technique "Heavenly Thunder Quenching Body Divine Light Technique", so that the physical body could accept the power of these dark thunders.

However, even if he operated the "Heavenly Dao Supreme Method" and the "Heavenly Thunder Quenching Body Divine Light Technique" at the same time, he still couldn't resist the destructive power of the Dark Thunder entering his body, and the flesh and blood organs on his body were completely destroyed, leaving only a complete skeleton of bones still struggling to support.

Yun Yi's consciousness was immortal, this was the second time he had fallen into such a situation, but this time his feelings were ominous.

In his consciousness, he was not damaged, the meridians were running, and the body organs were still there, but they had become a strange state.

Yun Ji's four daughters were unlucky, Yun Yi didn't expect that they couldn't dodge it, this kind of power of dark thunder was also affected even if they were hiding in the Zihua Immortal Mansion, and they were also refined by the dark thunder, but the power was much less.

However, Yun Ji is the most direct, she is the same as Yun Yi is directly facing the attack of the thunder, in desperation, she can only forcibly absorb the thunder, using her body's unique advanced technique, absorbing the energy in the thunder, forcibly advancing.

The last time she advanced was to absorb the power of the Heavenly Thunder, and this time she could be regarded as having some experience, and soon she adapted to the power of the Dark Thunder, and this process was actually much faster than Yun Yi.

The jade that Yun Ji turned into was constantly beaten out of impurities, and its size became smaller and smaller, and finally she couldn't stand it anymore, so she forcibly squeezed into the bones of Yun Yi's head and forehead to settle down, and began to gradually absorb the energy of the power of the thunder to make up for the damage she had suffered.

Ji Qing didn't have such luck, and the spirit of the divine sword on her body couldn't resist these yin thunders, so she had already been beaten out of the prototype and inserted next to Ji Qing to accept the refining of yin thunder, and she didn't dare to protect Ji Qing at all.

After Ji Qing resisted a few rounds of Yin Thunder Strikes alone, he had no choice but to use the Thunder Refining Technique, and in the blink of an eye, he turned into a skeleton of bones like Yun Yi, sitting cross-legged on the ground and struggling hard, always maintaining a trace of true spirit immortality.

The Blood Spirit Princess and the Blood Moon Princess were also refined by the Thunder of the Underworld, they were originally the bodies of the Underworld, but their own fate made them not directly transform into the power of the Thunder, but each manifested a different state.

The strange mark on the forehead of the Blood Spirit Princess resurfaced, turning into bursts of warm currents to protect the Blood Spirit Princess's whole body, and every time the Dark Thunder struck, part of the power of the Dark Thunder remained on her body, becoming an alternative way of refining the Dark Thunder, allowing her to keep her body intact.

The Blood Moon Princess coexisted with yin and yang, and she did not stimulate the thunder in her body, so that she remained unharmed.

The power of the thunder struck her body, as if it had not hit the real thing, and it pierced directly, leaving her unharmed.

made her the only one among the few people who had not been refined by the power of the thunder, and everything that happened here was as if it had nothing to do with her.

The Blood Moon Princess discovered her abnormality soon after, and she was surprised and a little worried, especially when she saw Ji Qing turn into a skeleton, she was even more shocked and inexplicable, and she didn't know what else she could do.

This situation has lasted for more than a month, and after the evil ghosts in the Ten Thousand Ghost Caves have basically been assimilated by the Dark Thunder, or all the evil ghosts and giant ghosts who have not been entangled by the Dark Thunder have fled from this place, so that the Sea of Dark Thunder no longer has a source of new thunder, and the Sea of Dark Thunder no longer expands, and begins to slowly weaken.

Yun Yi finally had some changes, and his whole body bones were refined into a substance like black jade by the thunderbolt, black as ink, exuding a terrifying fluorescence.

This is a process of transformation from life to death, and from death to life, and life and death, which makes him completely become a person with yin and yang, and can have a special physique with yin and yang thunder power in his body at the same time.

When Yun Yi's bones no longer accepted the power of the thunderbolt, and the bones no longer needed to be refined, flesh and blood began to slowly appear on his bones, and he slowly began to regain consciousness, and he could feel the operation of his own exercises.

Yun Yi's first thought was to drive the Supreme Euphorbia to begin absorbing the power of the Dark Thunder.

He estimated that there were no more demons here, and the power of these thunderbolts could not be wasted, just for the Euphorbia to absorb and store to increase the power of the Supreme Euphorbia.

When Yun Yi's body recovered a little, he hurriedly dodged into the Zihua Immortal Mansion, but he didn't expect the Zihua Immortal Mansion to be refined.

The entire Immortal Mansion has become like an underworld, and the dark sky has no light, and it looks dead and desolate.

"Ah, Childe, you're here, woo!"

Princess Blood Moon first found out about Yun Yi's arrival, and immediately couldn't bear it, and threw herself into Yun Yi's arms and cried loudly.

She has been guarding the entrance and exit of the Immortal Mansion, waiting for Yun Yi's arrival.

Yun Yi hurriedly calmed her down and asked her to take her to find Ji Qing and the Blood Spirit Princess.

Ji Qing still looks like a skeleton of bones, but her bones are also transformed into black jade like Yun Yi.

"Alas, Qing'er, it's my fault again, making you suffer again!"

Yun Yi sighed, but he had no choice at the moment, so he could only tap Ji Qing's forehead with his finger and pass on all the exercises of the "Heavenly Thunder Body Refining Divine Light Technique" to Ji Qing, so that she might be able to end the body refining earlier.

Ji Qing himself has no consciousness, but he is still able to accept the injection of external information, and can quickly integrate it into his own exercises.

The "Nine Heavens Xuannu True Solution" and the complete version of the "Heavenly Thunder Refining Body Divine Light Technique" made her bone refining speed also speed up.

The Blood Spirit Princess's skills have improved a lot unconsciously, which is ten million times stronger than her cultivation alone, her aura can't help but become stronger, and she has begun to have some dark thunder attributes in her body.

"Well, Ling'er seems to have cultivated an extremely clever underworld technique, and this kind of opportunity is not common.

Yue'er, don't worry, Ling'er doesn't have to worry about it. ”

Yun Yi nodded at the Blood Spirit Princess, he didn't know that the Blood Spirit Princess had made such progress, it was really relying on the power of those two Heaven and Earth Origins.

"Childe, are you fully recovered?

What am I going to do next?"

Xueyue'er asked weakly, she was a little lonely here, and seeing that everyone else had adventures, but she didn't, made her a little sad.

"Hehe, Yue'er, don't envy them, your chance is not here!

In my opinion, you will not be worse than theirs in the future!

Your ability lies not in these external skills, but in the power of destiny that is unknown to man.

When your chance comes, how can they compare!"

Yun Yi said that Princess Bloodmoon's thoughts made her feel better.

"Yue'er, you have to take care of your sister here, if there is anything abnormal about her, you can call me with your divine thoughts, and I will protect her well. ”

Yun Yi raised his hand and pointed at the Blood Moon Princess's forehead, passing on the Divine Thought Communication Technique to her.

"Oh, where are you going, boy?"

Princess Blood Moon asked hurriedly.

"Hehe, naturally it's in the thunder waterfall outside.

Seventh brother, my chance has just begun, how can I stop, when Seventh Brother I receive this Thunder Waterfall, it will be the time for me to leave!"

After Yun Yi said this, he reached out to hug Ji Qing's bones, flew into the thunder waterfall again, and came directly to the side of the Supreme Euphorbia, and sat next to it to cultivate.

The Thunder Waterfall here is actually the weakest place in the entire Thunder Sea, mainly because the Supreme Euphorbia can't stop absorbing thunder power, making all the thunder rush to the Supreme Euphorbia.

Yun Yi did not let Ji Qing go alone, but hugged him tightly in his arms, and began to tentatively absorb the power of the thunder.

This process was extremely slow, but as the power of the Dark Thunder continued to enter the body, the speed at which Yun Yi and the Supreme Euphorbia absorbed the Thunder Power gradually became faster, which was the reason why they were about to completely refine the Dark Thunder.

Under this mild and violent thunder environment, Ji Qing's bone refining speed also became faster, and within a few days, she completed the refining, and the bones also turned into black jade.

As she gradually regained consciousness, skin began to appear on top of her bones, slowly covering the various organs she had just generated.

Yun Yi suddenly had a feeling that this was a sign of the awakening of the system he was extremely familiar with, and he hurriedly sent Ji Qing back to the Zihua Immortal Mansion and let her cultivate and recover alone.

When he came to the side of the halberd again, he grabbed the halberd, and the system really began to exert force, and a huge force of attraction appeared, rolling the entire sea of thunder.

The power of the crazy thunder began to pour into the Supreme Euphorbia, and after the transformation of the Supreme Euphorbia, it forcibly entered Yun Yi's body.

Yun Yi didn't feel the slightest discomfort in this process, he couldn't help but laugh out loud as he saw that the Sea of Thunder that had almost made him lose his soul was like a wild horse that had escaped from his soul.

"Hahaha!

Hardship comes with no worries, and everyone knows who knows the blessings and misfortunes!"
