At this time, Yun Yifei arranged three sets of formations in the room of a cave, and then carefully checked them, and then he entered the space of the Ten Thousand Spirit Cauldron, and went directly to the Baibao Taoist, asking about the site of the Leiyuan Sect.

From the Baibao Taoist, he learned that the Nascent Soul cultivators and monsters from the seven forces had arrived not long ago. This made Yun Yifei a little confused. These distances were nothing to the speed of Nascent Soul cultivators. Why did it take so long? He also learned from it that Zhou Qing, the elder of the spiritual beast sect, was not the first to arrive.

But then I learned about the thoughts of these powerful Nascent Soul powers from the Baibao Taoist. After all, the resources in the Lei Yuan Sect site did not belong to any sect or force, so I was not panicked when the danger came. Because of the previous rumors, the strength of this demon cultivator was extraordinary, so these monks naturally did not dare to take risks alone, after all, there was no benefit to obtain it.

The Soul Refining Sect, the Witch War Sect and the Nascent Soul Cultivator from the Beast Transformation Sect went together.

The Amethyst Winged Lion King, the Iron-armored Flame Tiger and the Frost Giant Wolf, also went together.

Zhou Qing from the Spirit Beast Sect went there alone, and he arrived at the end, so it was naturally a way to protect himself.

When Yun Yifei heard this, he couldn't help but laugh and scolded the "old fox". Zhou Qing couldn't help but be cautious. After all, he is the only pillar of the entire Spirit Beast Sect. If there is an accident, even if the Spirit Beast Sect will not be affected by a catastrophe, its power will be reduced by half. If the three sects make a fuss, they will even swallow the Spirit Beast Sect.

Yun Yifei asked the Baibao Taoist again some methods and techniques for refining magic weapons. Although he had learned about it before, he couldn't help but feel a little excited and nervous when he wanted to refine magic weapons at this time, so he should ask more questions.

After he returned to his peak in all aspects of his body, he began to practice, because from the fierce battle with Cheng Zhen, he felt that his cultivation level was slightly loose.

"I can't blame myself and say that actual combat is beneficial to cultivation." Yun Yifei felt that the speed of cultivation was 20% faster than before, which made him very happy. You must know that from his advancement to the late stage of foundation building, the cultivation speed was pitifully slow, and based on his hard practice, it was just the help of the Ten Thousand Spirit Cauldron. Otherwise, his life expectancy would be approaching now.

Because the time rules in the cauldron are different from those in the outside world, although there are a one-horned fire bull and a savage horse waiting outside, he is not in a hurry and is practicing with peace of mind. After all, it only takes one day for a year in the cauldron.

A year later, Yun Yifei's cultivation speed slowed down again, and after practicing with the help of elixirs for more than two months, he stopped seeing no big progress. With a thought, he found that the little green thunder beast had stabilized his cultivation, so he came close to him and informed him in detail about the site of the Lei Yuan Sect.

Yun Yifei naturally asked it to seize the time to refine the secret realm and then enter the space of the Ten Thousand Spirit Cauldron. But at this time he found that the situation was even worse, because the site of the Lei Yuan Sect was no longer a Nascent Soul Stage cultivator, and even Lei Ling and Ba Xia Turtle might not be able to fight.

Yun Yifei was always worried and anxious, but when he heard the Xiao Qinglei Beast say that the ban was at the highest level even in ancient times. Although it was not fully activated at this time, it was not possible for several Nascent Soul cultivators to open it with brute force. As for the techniques of the ancient ban, the cultivation world may have been lost, so there is no need to worry.

Moreover, if there is a problem with the secret ban, the little green thunder beast will also be able to sense within a certain range. Yun Yifei was relieved and thought about it and then he left the space of the Ten Thousand Spirit Cauldron and put away several sets of formations.

At that time, Yun Yifei agreed to help the unicorn fire bull to refine magic weapons, and he and the two monsters came to a mountain. There were two tall stone doors in front of the mountain, with simple formation restrictions. Yun Yifei was confident that he could break it easily. After the two entered it, he saw this big one.

The mountain seemed to be hollowed out, but although it was very spacious, it was not much better than a natural cave. It was very simple. After all, for monsters, human arrangements were a bit redundant.

Yun Yifei didn't care. He just found a cave that wanted to restore his body to its best state before refining magic weapons. He casually found a cave like a room, arranged several formations and entered the space of the Ten Thousand Spirit Cauldron to practice.

Seeing Yun Yi flying out, the Unicorn Fire Cow and Liefengma hurriedly walked up. After a brief conversation, the Unicorn Fire Cow took out a huge piece of treasure refining material, which was full of fiery red, and hot energy spread out, so it was naturally a fire-attribute treasure refining material.

"What a big piece of material, how many magic weapons do you have to refine?" Yun Yifei couldn't help but say.

"This material only refines one magic weapon. The magic weapon requires the expansion of flame energy, and it must be based on thickness," said the Unicorn Fire Bull.

"This refining material weighs at least tens of thousands of pounds. Even after the material is purified, it may not be much lighter. If the restriction on increasing weight is imprinted, there will probably be many inconveniences to control it," Yun Yifei said.

"It's okay, only heavy weapons have power," said the unicorn fire bull with a smile.

"Since my senior has decided, I won't say much. What kind of magic weapon do you want to refine?" Yun Yifei continued to ask.

"Axe or giant hammer", the unicorn fire bull has long been thinking about it.

"The main force that the giant hammer swings is power. It is enough to refine a piece of material into a magic weapon. The power damage caused is naturally great, so there is no need to refine it into a giant hammer. I suggest that a double-sided axe can be used to release powerful power, and fire blades can be released from the axe blade. The proportion of materials occupied by the axe can be determined according to the requirements of the predecessors. What do you think?" Yun Yifei suggested after pondering for a moment.

"Yes", the one-horned fire bull saw that Yun Yifei was very sensible, so he quickly agreed, after all, the shape of the axe was within his consideration.

Next, Yun Yifei continued to determine the style of the axe with the Unicorn Fire Cow in detail. Of course, most of these were Yun Yifei's suggestions, and the Unicorn Fire Cow seemed to have no idea. Although he initially determined the magic weapon to create an axe-shaped figure, he did not consider it so comprehensively. For the first time, he saw that there were so many axes.

At the request of the unicorn fire bull, Yun Yifei had a prototype of the style of the double-sided axe and began to refine it. After all, the shape can be adjusted when refining.

The first step is to purify the materials. At Yun Yifei's request, the unicorn fire bull released a powerful flame energy to wrap the huge material. Under Yun Yifei's occasionally making magic tricks, the power of the flame can more fully invade the material.

The flame energy released by the unicorn fire bull is very powerful. From time to time, the black smoke produced by impurities is burned is released. As time goes by, the color of the treasure-refining material has changed from fiery red to deep red due to purification, which looks much thicker and more restrained.

While Yun Yifei was shooting out the magic trick, he was also observing the internal structure of this treasure-refining material. After the heat was right, the unicorn fire cattle released its power to temper the material at some specific locations, so that the material became more tight and solidified without changing its internal structure as much as possible.

Yun Yifei is much more relaxed with the Unicorn Fire Cow, and only provides technical guidance. After two days and two nights, the material was purified. The color was dark red, which seemed thicker than the previous color.

After a brief discussion with the unicorn fire bull, Yun Yifei began the next step of operation, casting.

It was still the coolie of the Unicorn Fire Bull. After the powerful flame energy melted the material that had not been reduced much, Yun Yifei had already prepared a spiritual sense and spiritual power into the material, and pulled out a part of the material as a handle, as his special one.

Under the control of intention, the axe handle is not straight, but slightly curved. Moreover, the axe handle is not round and smooth, but slightly rough, and even retains the texture formed by the elongation, which makes it more rough and more suitable for monsters.

"It's great," the one-horned fire bull is very satisfied with the axe handle.

Under Yun Yifei's control, large pieces of material spread out on the axe, like a round tabletop, thick in the middle and thin around it. There is a narrow space upward in the middle of the disc, which divides the disc into two axes, showing a perfect arc at the junction between the disc and the axe handle, as if it was natural and looked very comfortable.

After the double-sided axe was formed, the Unicorn Fire Cow was very satisfied. This was the best shape he wanted. When Yun Yifei asked if he needed to add some patterns to decorate, the Unicorn Fire Cow mercilessly refused. This style had already made him very satisfied.

Yun Yifei nodded. I have to say that such a double-sided axe looks very bold. Although it was refined by a monk, there are some primitive elements contained in it, which is very suitable for the strong one-horned fire cattle in front of it.

"Since that's the case, I'll engrave the magic tricks." Yun Yifei greeted him, and the powerful spiritual power surged, and one by one was released. The first thing he had to do was to reduce the double-sided axe. After all, this giant axe was more than ten feet long at this time.

Yun Yifei condensed the magic tricks and released them as fast as flowing water. After all, he has refined many magic weapons and is often used such magic tricks. Basically, every normal magic weapon will use such magic tricks to shrink to a slightly smaller size than a slap.

There are many more magic weapons that require seal carving than magic weapons. As Yun Yifei shot into the double-sided axe, the magic weapon gradually shrank. When it became about a meter long, the one-horned fire bull shouted to stop, and this length was suitable for him.

Next, Yun Yifei's transformation technique continued to penetrate the magic weapon, including those with amplification, weight increase, etc. Although there were not many types of technique used, there were quite a few techniques to accommodate them. After some operation, Yun Yifei's spiritual power was left.

"Senior, what else should I add?" Yun Yifei finished engraving a series of magic tricks.

"No need to fill it up, it's perfect, I'm very satisfied." The unicorn fire bull laughed and wanted to take the two-sided giant axe into his hand.

"Okay," then Yun Yifei threw several magic tricks into the double-sided axe. After finishing the work, he completed the refining of this magic weapon.

"The magic weapon has been refined. You only need to brand the magic mark in it and leave essence and blood. This magic weapon is considered the magic weapon of your senior." Yun Yifei sat on the ground. Although he had the help of the Unicorn Fire Cow, Yun Yifei also consumed a lot. You should know that it took more than ten days to refine this magic weapon, and this was still with the help of the Unicorn Fire Cow.

After the unicorn fire bull couldn't wait to complete the magic weapon, he clearly felt the intimate connection with the two-sided giant axe. His body jumped out into the air and waved the giant axe to practice. Several giant mountains were easily split by the axe lights. This power made him very satisfied. Then he raised his body again and waved it towards the sky. Axe lights with flames were slashed out, twisting the space wherever he passed, as if he could really open the sky.

"Fellow Daoist, give this magic weapon a name." The Unicorn Fire Bull was very happy, and he still looked excited after landing.

"Senior, what do you think you are called the Kaitian Battle Axe?" After all, this magic weapon is a one-horned fire bull. Yun Yifei didn't want to name it, but no matter what, this is the first magic weapon he refined. Even with the help of the one-horned fire bull, Yun Yifei was very satisfied and proud. He swallowed the words he rudely and then spoke.

"The Kaitian Battle Axe, a good name, domineering enough, so I'll call it this name."
