This was a small piece of compound Restriction made up of about a hundred Restriction. However, Lei Xingfeng couldn’t recognize it. He couldn’t understand what Restriction it was.

After pondering for a moment, Lei Xingfeng wanted to erase this Restriction. After all, it hadn’t been long since it had appeared. It would be easy to erase it.

However, Lei Xingfeng quickly stopped. He thought of a problem. This Restriction community was in a corner. Even if it grew up, it would not affect the central region. So there was no problem staying there. Most importantly, he could not understand this small Restriction community. Then, he would wait until it grew up before carefully observing it.

Very quickly, Lei Xingfeng threw this matter to the back of his mind. He no longer paid attention to it. His attention was focused on the central community. The three Lei Yin needed to be dealt with by him. When cultivating, he could not be distracted randomly. Every Lei Yin had to take care of it.

Three Lei Yin, one main and two auxiliary. The main Lei Yin was his original seal. There were Xiao Kong and lightning-type spirit creatures living there. The two spirit creatures suppressed the spirit creatures in the auxiliary seal. What Lei Xingfeng wanted to do now was to increase the Restriction community. After reaching a certain upper limit, he would superimpose another auxiliary seal.

By the time the first master and the eighth mate arrived, Lei Xingfeng’s Lei Yin would be able to enter the legendary cultivation mode of fusing nine Lei Yin. However, this was only a legend. It was said that there was such a fusion mode in ancient times that could reach a truly heaven-defying position. It was not too much to call it a god.

A large number of energy crystals were rapidly being consumed. If it weren’t for the large number of crystals he had obtained this time, Lei Xingfeng would have felt heartache. Too much energy crystals had been consumed in a short period of time. However, because of the cost-neutral stimulation, the energy crystals in Lei Yin had truly undergone tremendous changes.

A large number of Lei Yin emerged from the main Restriction. At the same time, the associated Lei Yin would also appear in the secondary Restriction. They would contact each other and grow together. Restriction communities would form one after another, and they would grow rapidly under the support of countless energy crystals.

All Lei Xingfeng had to do was erase the useless Restriction and maintain the growth of the Restriction community.

The materials he had collected in the past were basically stored in Lei Yin. With Xiao Kong around, the storage space in Lei Yin was no worse than the storage space in Lunzang. He could also store a large amount of materials. Of course, the materials stored in Lei Yin were not so easy to retrieve.

In Lei Yin, as long as Lei Yin grew up in Restriction, the materials would be constantly consumed and would not be controlled by Lei Xingfeng.

Because Lei Xingfeng drove Lei Yin crazily, Restriction formed very quickly. Lei Xingfeng’s mind was also focused on the Restriction that appeared, some of which he did not want, and he was busy erasing the messy Restriction.

A large amount of energy crystals were stored in the Lei Yin, so this kind of drive consumed energy from the Lei Yin. There was no need for Lei Xingfeng to reinvest in the energy crystals.

Therefore, Restriction grew at an unparalleled speed. He appeared at first sight and then grew rapidly until he was completely formed. He could also play a role.

When Restriction could play a role, Restriction began to work together to form Restriction communities. This was what Lei Xingfeng called compound Restriction. If Lei Xingfeng were to set up such a Restriction, it would be a headache, and in Lei Yin, it would naturally form.

Lei Xingfeng discovered that there were many spatial Restriction appearing. He warned Xiao Kong slightly. After all, his seal was Lei Yin, not the spatial seal. If he were to be completely occupied by the spatial Restriction, his seal would definitely collapse. The basis of the seal was the lightning attribute. If he created the spatial Restriction, then the seal would basically be completely destroyed.

It was impossible for Lei Xingfeng to let such a thing happen. There were some spatial Lei Yin in Restriction that weren’t bad things, but all of them were spatial Restriction, so Lei Xingfeng wouldn’t be able to survive.

Controlling the spatial Restriction to within 20% was the ratio given by Lei Xingfeng, and he repeatedly told Xiao Kong.

Xiao Kong couldn’t do anything about it. Quantity wasn’t enough. He tried to work hard on quality. The spatial Restriction he came out of was becoming more and more advanced. This forced the lightning-type spirit to increase the power of his Restriction. Although it wasn’t as powerful as Xiao Kong, the lightning-type spirit had an advantage in quantity.

After an unknown amount of time, Lei Xingfeng discovered that the Lei Yin in Restriction had more than doubled. The amount of materials and energy consumed made him feel shocked, too much.

However, Lei Xingfeng also found that he could barely superimpose Lei Yin. However, he did not dare to do so for the time being. With his experience, especially his knowledge of Restriction, he felt that doing so was not good. For the time being, he had no choice but to stop cultivating. Lei Yin had already reached its limit and needed time to digest it.

Although he hadn’t advanced, Lei Xingfeng knew that his strength had risen by a large margin. He probably still couldn’t do anything to Ai Yao, but he wouldn’t feel that terrifying anymore.

He stood up and returned to the Mirror Realm, arriving at the Mirror Realm’s warehouse. He needed to replenish some materials.

Wu Yang and the others were still tidying up the warehouse. Back then, Lei Xingfeng had gathered too many energy crystals. The amount of energy crystals in a pit was not much different from that in a small mountain. The amount of energy crystals was enormous to the extreme, and it would take a long time to clean them up.

Seeing that Lei Xingfeng was coming over, Wu Yang and the others also stopped what they were doing. Gu Qi smiled and said, “Our great meritorious heroes are here.”

Wu Yang said, “Feng, this is the first time I’ve seen so many high-quality energy crystals. I’ve made a lot of money this time.”

Lei Bao said, “Feng, why are you back? I heard from Kitty Eagle that you went to cultivate. How was it? Has Sihuan true body returned?”

Lei Xingfeng smiled and said, “How can it be so fast! However, it is also very fast.”

Everyone was shocked when they heard this. The speed of cultivation was simply frightening.

Wu Yang said, “So fast! Is there any secret?”

Everyone immediately pricked up their ears. They were all middle and upper echelons of the secret sect. Their strength was considered to be at the peak within the secret sect. Any experience from Lei Xingfeng was incomparably precious to them.

Lei Xingfeng smiled and said, “There are no tricks. If you insist on saying something … it’s also the consumption of materials and energy. It’s very frightening. My materials have basically been used up by half. There’s no need to mention the energy. It’s even more terrifying. Some of the materials have been completely exhausted. I want to look for some replenishment in the warehouse.”

Wu Yang said, “Yes, there are a lot of materials. Haha, the disciples of the secret sect exchange materials for energy crystals. If you look for them yourself, you should be able to obtain a lot of useful materials.”

Lei Xingfeng nodded and walked into the warehouse.

The warehouse was built underground and had a huge area. There were dozens of warehouses, half of which contained energy crystals. Lei Xingfeng entered the material warehouse to collect the materials he lacked.

Along the way, Lei Xingfeng discovered a lot of materials he needed. However, there weren’t many high-grade materials, but the basic materials were piled up like mountains.

After spending a few days, Lei Xingfeng replenished a large portion of the basic materials. These materials did not need to be high-grade, but they could not be lacking. In addition, he gathered a portion of steel and planned to forge a weapon for himself.

After pondering for a long time, Lei Xingfeng finally decided to refine a steel rod. There was no way to refine a steel rod, and neither a sword nor axe was suitable. Instead, it was the steel rod that was the most suitable.

Using Lei Yin to refine such a simple steel rod was an extremely simple matter for Lei Xingfeng. However, after the steel rod was finished, Lei Xingfeng had other thoughts.

Just like the sword imprints of the past, placing Restriction on the steel rod became his weapon of experimentation.

Because the steel rod was extremely thick and long, the water tank was thick, and was a hundred meters long, its weight could be easily used by the real body. If it was the main body, not to mention using it, it would not even be able to shake it.

The Thunder Killing Array had to be set up. Lei Xingfeng even wanted to set up a space within it. Only when he discovered that there was a lack of materials did he let it go. Therefore, the steel bars were basically set up with lightning Restriction.

As for Restriction such as reinforcement, Lei Xingfeng had also arranged quite a few. Of course, this kind of Restriction could not be compared to the sword imprint. The two were not the same meaning. This weapon was mainly won by weight. Adding these Restriction, it was even more abnormal.

After tossing and turning for a long time, he finally finished refining the weapon.

This steel rod was about a hundred meters long, and it was dark in color. Occasionally, arcs of electricity would appear on its surface, causing the steel rod to crackle. Once combined with Lei Yin, it could release a large amount of lightning bolts.

Lei Xingfeng released his true body and raised the huge steel rod with one hand. He felt that it was very handy and waved it.

With a whoosh, he casually smashed into the ground.

Boom!

Even with a light blow, Lei Xingfeng didn’t even exert any strength. He opened a hole in the ground, causing Lei Xingfeng’s eyelids to twitch. If this hit the real body, his opponent would probably not be able to stand it.

Lei Xingfeng thought that if he had this giant stick in his previous battle with Ai Yao, even if he couldn’t break through his defense, he would at least have to increase his energy consumption by a large margin. If he was careful, Ai Yao might not have that much energy to consume. In other words, he could consume it to death or run away.

Lei Xingfeng thought for a moment, then put the steel rod into Lunzang Space, and then refined a weapon again. This time, he planned to refine a super giant machete. It was only 60 meters long, and the blade was at least 7-8 meters wide. Its shape was similar to a mountain cleaver.

Compared to the steel bar, it was considered a short weapon. After refining it, he also laid out a lightning Restriction. Actually, he knew that this kind of mountain cleaver did not rely on the blade to injure people, but on the weight of the blade itself. As for why he refined this weapon, it was because Lei Xingfeng had a set of saber techniques he had learned in Huya Castle.

Lei Xingfeng didn’t know much about using sticks. He was using spear techniques instead of sticks. On the contrary, he was very proficient in saber techniques. Back in Huya Castle, he practiced one spear technique, one saber technique, and one archery technique. He didn’t use any archery techniques at all, but saber techniques and spear techniques were still useful.

Especially the saber technique. Lei Xingfeng was even more familiar with it. It was just that it had been a long time and he was a little rusty. He could just practice it for a while.

Very quickly, the Mountain Cutting Saber was finished and the lightning Restriction was laid out. However, when Lei Xingfeng looked at the huge Mountain Cutting Saber, he couldn’t help but shed cold sweat. It was too big. If he had used this giant saber back then, he would have been able to smash the Barbarian Bull into meat pancakes in an instant.
