Ai Qi and the others knew all this, but they didn't say it clearly. They would vaguely stop. If you are smart enough, you will definitely be able to hear the meaning of it.

Fortunately, Lei Xingfeng has escaped from this battle. If it continues, God knows whether he can save his life. There are all kinds of situations on the battlefield, and it is not just about strength. Sometimes luck is more important. Of course, don’t go to the best way to save your life.

Lei Xingfeng has lived a good time this time. Wu Yang has disappeared on the battlefield and is determined to be dead. There are too many missing people. One less Wu Yang will not attract attention at all. Lei Xingfeng does not want the ancestor to continue taking risks. Their purpose has been achieved. Lei Xingfeng successfully intervenes in the Mingze League and allows Wu Yang to continue to stay in the army. It is too stupid. There is only one Taoist ancestor in the secret sect. If there is anything wrong, the entire secret sect can't stand it.

All the ban masters and escorts followed Lord Qingyan to the ban circle and stopped under a mountain peak. There was a high tower and a building community. Lei Xingfeng immediately understood that the ban hub would definitely be arranged here, either on the defensive tower or in a certain building. This long-term large-scale composite ban hub must be maintained regularly. Once the energy is insufficient, it must be replaced in time.

Therefore, the core of the ban hub must be strictly protected. This is a ban hub placed in an open place and is also a general method of large bans.

Lei Xingfeng lived in a building, but he didn't rest. He followed Qingyan, Hai Yuanlong and others, watching how the ban hub was arranged. In this regard, the high-level ban hall of the ban hall would not stop it. If you want to learn, that is the best attitude. In the ban hall, you are afraid that you will not learn. As long as you are willing to study, any advanced ban master is very welcome. This makes Lei Xingfeng very satisfied. There is no sense of confidentiality here.

It’s relieved to think about it. As a giant like Mingzemeng, they are not afraid of you to learn secretly, nor are they afraid of intruding into a few people with ulterior motives. When their strength reaches a certain level, they have already ignored these people and things, because no matter what you do, you are nothing to a huge force and strength like Mingzemeng.

This is a large composite ban combining psychedelic, defense and killing arrays, which can block and kill people trying to enter. However, for Lei Xingfeng, this ban array is useless. He has left coordinates in the ban circle and dug up a hiding place. As long as he wants to come in, he can enter it at any time.

This is the gift left to the younger sister by Lei Xingfeng. This import and export can pick various spiritual herbs and medicines at any time. Of course, Lei Xingfeng will not let the younger sister take risks. As long as he has the chance, he will pick them himself. You must know that he can see various treasures, and these eyes are the guarantee of the treasures he has obtained.

When Qingyan set up a ban hub, Lei Xingfeng was right next to him. He stared at Qingyan's every move and saw how he set up a ban hub. As for Ai Qi and his group of people, they had long known where they had gone. They had no intention of following Qingyan. Only by being with their own group of people was free and active, with Lord Qingyan? Just kidding, isn't this just to have the awareness of being abused?

The ban hub is quite complex. Lei Xingfeng found that the ban hub designed by Qingyan is quite clumsy. During the conversion period, there is a considerable gap period. If a person who is a good person can use this gap, what he pays most attention to is the energy crystals used by Qingyan.

Now Lei Xingfeng knows that there are all kinds of crystals in this world, including the earliest seal ring, which is a crystal, as well as holy crystals, Tianyan crystals, Da Lei crystals, ice crystals, etc., all of which are energy crystals, but he doesn't even know the crystals used by Qingyan.

When Qingyan was resting, Lei Xingfeng asked, "Sir Qingyan, what crystal are you using?"

Qingyan looked at him a little surprised and said, "This is a composite crystal, the full name is multi-layer Jiaji macrocyclic crystal, which is made up of several natural crystals, referred to as the macrocyclic crystal, which is a commonly used energy source for our banned masters. Well, the macrocyclic crystal also has different quality. I am using high-level macrocyclic crystals now."

Lei Xingfeng couldn't help but smile bitterly, and he said, "I have never been exposed to this kind of crystal, the large ring crystal, it seems to be very powerful."

Hai Yuan Long said: "The big ring crystal is unique to our Mingze League. There is no such crystal in other places. This invention was invented by a ban master of the General Hall. As long as the senior ban master can refine it, it only requires a little insight into the refining of this crystal, otherwise it will be difficult to succeed."

Qingyan took out a page of Star Python Records and said, "You can record it yourself. It is not a secret to refining the Great Ring Crystal. However, people with insufficient abilities should not try it. If this thing is not refined well, it will explode."

Lei Xingfeng hurriedly took over the Star Python Record, and he thanked him repeatedly. Qingyan said: "This is your reward for completing the mission this time. Are you willing?"

Of course he was willing, Lei Xingfeng kept nodding, joking, he didn't care about rewards or something, but if it were this, he was absolutely satisfied and said, "I'm willing, just this reward!"

Qingyan then let go. Lei Xingfeng took the Star Python Record and immediately began to copy a copy, returning the original to Qingyan, and then watched it carefully.

The large ring crystal requires ten kinds of materials, including several crystals and several auxiliary materials, which are not complicated to refine. The key is the timing of refining, as well as weight and experience. This level is difficult for many banned masters. Lei Xingfeng is quite interested in refining things, so he just took a rough look and knew that as long as he was careful, he would definitely be able to refine the large ring crystal.

There are four types of large ring crystals, one is the lowest-level large ring crystal, one is the ordinary large ring crystal, and the other is the advanced large ring crystal. The last one is relatively rare and will be refined by chance, which is the perfect large ring crystal.

The materials used to refine large ring crystals are not particularly expensive and scarce. Lei Xingfeng just took a quick glance and knew that these materials were included in the secret sect, and there were quite a lot of them. There were two main materials, and they were in the mining area of ​​the Taigu Continent. The mining area they secretly dug was produced in large quantities. At the beginning, Lei Xingfeng didn't know that this thing was used on it. If you have the chance to go back, you must remind Wuyang and others to dig more.

Lei Xingfeng said: "Old Hai, do you have a big ring crystal? Let me see it."

Hai Yuen Long took out four large ring crystals casually and said, "You can see these four large ring crystals by yourself. Well, they are what I gave to you."

At this time, Lei Xingfeng finally had an intuitive impression. The lowest-level large ring crystal is like colorful jade, completely opaque, with a smooth surface, very beautiful. The ordinary large ring crystal is a bit like a layer of glass. Although it is opaque, it is full of colorful light and even more beautiful.

The high-level large ring crystal is translucent and emits colorful light. I think it is a polished crystal. After reading the records of the Star Python Record, Lei Xingfeng knew that this was naturally formed after refining, not deliberately polishing, and generally appeared in hexagonal or octagonal shapes.

The perfect-level large ring crystal is only the size of a finger, completely transparent, and it emits colorful light directly from the inside. According to Lei Xingfeng's eyes, this thing looks like a cut diamond. Unlike diamonds, diamonds will not emit light without light. The perfect-level large ring crystal shines with colorful light even in the dark, which is very exquisite and beautiful.

Lei Xingfeng held the perfect large ring crystal and couldn't help but say, "Beautiful! This thing is very valuable, right?"

Qingyan said: "In Mingzemeng, this is hard currency, and you can exchange it for various materials."

Hai Yuen Long said: "Only the ban master can refine it, because refining this thing requires understanding of the ban."

Qingyan said: "I will give you the records of Star Python Records. There is a description of how to refine them. You can think about it yourself."

This harvest made Lei Xingfeng extremely satisfied, but he didn't expect that there would be such a big harvest on his trip.

About ten days later, all the bans were arranged and the ban hub was completely set up. Qingyan planned to try to start. This large composite ban array will require a certain amount of debugging after being started. Many people will also need to specifically test the power of the ban array. However, once activated, the task of Hai Yuen Long and others will be completed. Lord Qingyan will continue to stay here, but others can leave.

When the entire compound formation was activated, Lei Xingfeng was surprised to find that this formation was quite not simple. Although it was not as powerful as the forbidden area that he had seen before, its power was already quite extraordinary.

Through the secret gate, Lei Xingfeng followed Hai Yuanlong back to Mingze Continent. This task was completed. In addition to receiving the reward of the refining method of the Great Ring Crystal, Lei Xingfeng also received the reward of the Refining Hall, and ten advanced healing potions. Lei Xingfeng gave Kuqi and four people casually, two of them each, which made the four guys so happy that they couldn't stop.

There is no such good treatment in the supervision team. Only by making great contributions can you get advanced potions. This time I went to the other continent and did nothing, so I got two advanced potions. The four of them were very satisfied.

After two days of rest, Lei Xingfeng came to Hai Yuen Long's residence again, and he still had one more task to complete.

Hai Yuen Long brought more than a dozen ban masters this time. As a ban master, he could receive many tasks as long as he wanted. Of course, the ban masters of the ban hall rarely compete for more tasks. They make countless ways to make money, and they earn countless ways to earn materials. There is no concept of money here, and most of them are bartered. However, there is also hard currency in the Mingze League, and anything can be exchanged. The ban hall is the Great Ring Crystal, and the Refining Clan Hall is the potion.

Lei Xingfeng saw Hai Yuanlong and smiled and said, "Old Hai, what is the mission this time?"
