Lei Xingfeng released the tray made of thunder bones. This was a tray made by Xin Zhaolun when he was still in Hanya Castle. Several materials were placed on the tray. These materials were placed in order.

Lei Yin was originally made of bones. After so many years of cultivation and nourishment, the white bones had already changed from white to silver. Later on, Lei Xingfeng had also added a lot of materials to strengthen the bones. This Lei Yin had expanded a lot. The nine apertures Lei Yin.

Nine Apertures Lei Yin, Back then, it was made of red gold, It seemed that the red gold was too low-grade. It couldn’t withstand the baptism of powerful lightning. Earlier, when he used the golden liquid, Lei Xingfeng had a very clear feeling that Lei Yin was overwhelmed. This was just the beginning. How to further it became a problem. Therefore, Lei Yin and Lei Xingfeng had to cultivate again. Regardless of whether he was willing or not, he had to refine it again.

Now that Lei Xingfeng had a better and stronger metal, it could replace the core parts of the nine apertures. The overall structure of Lei Yin had not changed. The Lei Yin structure diagram he had obtained back then was quite formidable. It was actually extremely similar to what he had obtained here.

After carefully selecting the ingredients, Lei Xingfeng began to carefully replace them. He didn’t need to use his brain to completely test his ability to do so. From the beginning, when he was unfamiliar with the ingredients, he quickly adapted. After all, he had already made a Lei Yin.

Once the Lei Yin elementary body is complete, According to the records on the wall, Lei Yin could automatically swallow the materials. When he swallowed enough materials and had enough energy, Lei Yin could automatically upgrade at the same time. That was to say, the first step had to be manual. After the formation of self-circulation, there was no need for Lei Xingfeng to worry about the subsequent upgrading. As long as he provided the materials and energy, it would be very advanced.

So when Lei Yin’s silver light shone with a hint of gold, Lei Xingfeng finally breathed a sigh of relief. In this short period of time, he had consumed more than a dozen basic materials. The largest amount of metal was all produced here. Even the Lei Yin foundation made from Thunderous Beast bones had its attributes changed. Threads of metal seeped into it, changing the quality of Thunderous Beast bones and improving Lei Yin’s quality.

After letting out a long breath, Lei Xingfeng said, “It’s quite difficult. Fortunately, it went smoothly. Some minor flaws will gradually become perfect in the automatic ascension in the future.”

Jing Ziya said, “This is a large household that eats ingredients and energy. I don’t know how many things you need to swallow to reach the peak.”

Lei Xingfeng shook his head and said, “That’s not what I need to consider. I just need to be responsible for collecting materials and energy. The best way to replenish my energy now is to use thunder, liquid and plasma. It’s much stronger than the crystals we’ve obtained.”

Jing Ziya said, “This is incomparable. One is liquid thunder and lightning, the other is energy storage crystals. The difference between the two is too great. Lightning, liquid, and plasma are both unattainable in our era.”

Lei Xingfeng said, “Hehe, I didn’t expect that there would be a pool here. Why didn’t anyone take it away back then?”

Jing Ziya said, “It’s very simple. This is when they leave and gather again. Do you think the lightning outside was struck for nothing?” “When the lightning strikes, a small portion of the energy should have been converted into lightning liquid plasma. If the lightning liquid plasma here is still unharvested, perhaps it will overflow after thousands of years. At that time, the entire room will probably be destroyed.”

Lei Xingfeng admitted this. Lightning plasma was simply too tyrannical. If there was a small amount of it, it wouldn’t corrode the metal. However, once there was a large amount of it, its properties could melt everything. When using it, one had to be extremely cautious.

However, there was no need to worry about using Lei Yin to absorb it. Lei Xingfeng would not directly throw Lei Yin into the pool of lightning liquid plasma. That was not charging, but destroying Lei Yin. As long as Lei Yin was suspended above the pool of lightning liquid plasma, Lei Yin would automatically absorb the lightning liquid plasma until Lei Yin was unable to absorb it.

And then you add the ingredients and you form a cycle that allows Lei Yin to grow on its own.

Lei Xingfeng is going to do the experiment now.

Jing Ziya was also very curious. Even in her day, Lightning cultivators were also extremely rare. Moreover, most of them were extremely mysterious and were strictly forbidden to provoke by the various forbidden areas. However, because there were very few lightning type cultivators, even if they were extremely powerful, they would not pose a great threat. This was different from the thousands of lightning type cultivators in the forbidden area. Tens or dozens of lightning type cultivators, even if they were top experts, would find it difficult to fight against the forbidden area.

However, lightning cultivators were extremely powerful. Once those people left the protection of the forbidden area and faced lightning cultivators, it would be extremely dangerous. This was also the reason why the people in the forbidden area rarely provoked lightning cultivators.

Lei Yin slowly hung above the pool of lightning plasma and slowly descended. As he approached the surface of the pool, Lei Yin remained motionless.

A foot long arc of lightning leapt up and instantly sank into the Lei Yin.

Because Lei Xingfeng and Lei Yin had already become one, he felt the same way. That huge energy caused his entire body to tremble, and his body couldn’t help but tremble violently. He was only a meter away from Lei Yin.

Jing Ziya saw a strange scene.

Lei Xingfeng stood by the side of the pool. Lei Yin was hanging by the side of the lightning plasma. A foot long arc connected to Lei Yin. A huge amount of energy was continuously absorbed into Lei Yin. Then, countless fine arcs of lightning were emitted from Lei Yin and connected to Lei Xingfeng’s body.

Chi chi sounds, even covering the thunder outside.

Lei Xingfeng’s long hair began to stand up, and his head became incomparably large. His body trembled like withered leaves in the wind. He was truly trembling.

The fine lightning bolt was rapidly changing Lei Xingfeng’s body. This was a strengthening process. Because there was a golden liquid in front of him, Lei Xingfeng was able to withstand this level of strength. Not to mention cultivators, even lightning cultivators did not have the first procedure. This fine lightning bolt could directly melt people.

The moment the lightning bolt struck Lei Xingfeng’s body, everything on Lei Xingfeng’s body was reduced to ashes and his body was completely naked.

Lei Xingfeng is not thin, If he had such a figure in his previous life, He would probably wake up laughing in his dreams, This was the standard size, and his muscles weren’t exaggerated. It was extremely gentle, but it could be seen that it contained explosive strength. Especially the six-pack abdominal muscles, it was even more clearly discernible. Of course, Lei Xingfeng didn’t care about his body at all. He was shaking so hard that it was very difficult to control his body. This was a passive body strengthening process, not something he could control.

Jing Ziya looked at Lei Xingfeng amusedly. She knew that Lei Xingfeng was not in any danger, Lei Yin and Lei Xingfeng were almost one. As long as Lei Yin didn’t explode, Lei Xingfeng wouldn’t be injured. It was just that he was trembling too much. The most peculiar thing was that Lei Xingfeng’s muscles were twitching all the time. Of course, she didn’t feel anything about Lei Xingfeng being completely naked. She was a doll, not a human. She didn’t feel like a woman.

Lei Xingfeng saw the strange smile on Jing Ziya’s lips. He didn’t know that Jing Ziya was shaking because she was ugly. He thought that she was mocking him for being naked. He said, “You, you, you … laugh, what are you laughing at … What … I, I … damn it … numb to death … numb to death!”

Jing Ziya immediately smiled and said, “It tastes good, hehe.” She sarcastically said.

Lei Xingfeng said, “One … one … one side … one side!”

Jing Ziya held her chin and said with a gloating expression, “I can’t leave. I’m responsible for your safety!”

Lei Xingfeng helplessly said, “No, don’t laugh …”

Jing Ziya immediately stiffened her face, as if I wasn’t smiling. Lei Xingfeng decided to stop pestering her and quarrel with Jing Ziya. It was really not the right time. His mind was almost blank. His words were all subconscious and he didn’t think at all.

After trembling for a day, the empty Lei Yin could only absorb enough energy. There was almost no change in the entire pool of lightning liquid plasma. Lei Xingfeng estimated that he had consumed only a hundred drops of lightning liquid plasma to fill up Lei Yin. From this, it could be seen that Lei Yin was not strong enough.

The moment Lei Yin returned to her body, Jing Ziya couldn’t help but take a step back. At this time, Lei Xingfeng was as dignified as a mountain. That aura was simply incomparably tyrannical.

Jing Ziya said, “Quickly collect your strength!”

Lei Xingfeng slowly sat down and tried to adapt his body to Lei Yin. The intimidation gradually disappeared. Soon, Lei Xingfeng completely recovered. He shook his head and patted his forehead with his hand, saying, “Amazing! This is unbelievable!” After he completely accepted Lei Yin, he immediately knew that his strength had definitely increased by a large margin.

This was the result of just cultivating. Once he finished cultivating the cultivation technique recorded on the wall, he didn’t know how far his strength would increase.

Once Lei Yin succeeds, Lei Xingfeng is already half-successful, because Lei Yin is the foundation, just like building a house. Once the foundation is laid, it won’t be a problem to build a house on it no matter how hard it is.

Lei Xingfeng was in excellent spirits, but he felt hungry again. This time, he brought Jing Ziya back and returned to his home in the Jingzhi Realm.

Although Lei Xingfeng had already absorbed the might that Lei Yin had spread out, when he stood in front of Jin Daya and the others, that faint terrifying aura still shocked Jin Daya and the others.

Jin Daya said, “Feng, have you successfully cultivated?”

Lei Xingfeng smiled and said, “How is that possible? It’s just the beginning. I just finished cultivating Lei Yin, and I didn’t have time to cultivate anything else. Oh right, where’s Big Fatty? I’m almost starving to death!”

Jin Daya and the others were speechless. As long as this fellow came back, he would eat and drink like a starving ghost.

Feng Ying asked, “You can eat there too. Why do you have to come back to eat?” He knew that Lei Xingfeng usually carried a large amount of food, so he shouldn’t starve himself.
