Because this is truly hard to find in the world!

Ten thousand years ago, Zhan Wuque searched for the world but couldn't find it, which shows that it was rare.

Slowly open the jade box, and a gray-brown mud ball of beans the size of a bean are printed into your eyes.

Yunni looks very ordinary. Even if it is thrown on the roadside, no one will recognize it.

Although it is only the size of a bean, it is rare in the world.

"There is not much cloud, but at least two weapons can be added."

Zhan Wuque thought about it and took out the star core.

The star core is the strongest treasure he has sacrificed so far.

Although the star core is extremely hard and extremely difficult to destroy, the star core is related to the "Six Paths of Reincarnation" and cannot be missed.

Zhan Wuque breathed a sigh of relief, and the Jiuzhou Cauldron landed on the ground with a bang.

Jiuzhou Cauldron can not only refine alchemy, but also refine weapons.

The strange fire spurted out and began to burn.

But Yunni is not ordinary refining materials, and it has not changed for a while.

"The temperature seems to be a little worse," Zhan Wuque frowned slightly.

He took the strange fire back into his body and then took out two balls of demon fire.

One blue and one red.

Two balls of sixth-level demon fire.

This is the apology given to him by the Yuwen family not long ago.

The seventh-level demon fire, he now has two balls.

One is the result of killing the imperial concubine of the Daxia Dynasty, which is a seventh-level low-grade demon fire.

Another is the reward for the alchemy competition, the seventh-level glazed fire.

This glass fire is of the middle grade of the seventh grade by grade, but its actual power is equivalent to the top grade of the seventh grade.

Because its special features are between tangible and invisible, they are very rare, and they are also something that can be encountered and hard to find in the seventh-level demon fire.

Zhan Wuque sat cross-legged and began to refine.

It took three hours to finally finish refining.

"call!"

Zhan Wuque breathed lightly, opened his eyes, and a trace of regret appeared in his eyes.

Unfortunately, one of these two balls of demon fire is a low-level sixth grade and the other is a medium-level sixth grade. After devouring it, his level of strange fire has not been improved, and he maintains his original level and a medium-level sixth grade.

Zhan Wuque could vaguely feel that to reach the top level of the sixth level, at least two balls of sixth level middle level demon fire, or a ball of sixth level top level demon fire.

However, although the level of the strange fire has not been increased, the power of the flame has been increased by three points.

"Although it didn't meet the expectations I wanted, it was enough."

Zhan Wuque said to himself.

In fact, this was also within his expectations.

If you want to upgrade the strange fire, it will be more and more difficult to go up.

If you want to upgrade to the middle level of the sixth level and reach the top level of the sixth level, it is far from enough to rely on two balls of demon fire.

After putting away his thoughts, Zhan Wuque took out the cloud mud again and put it in the Jiuzhou Cauldron to start refining.

Time passes slowly, and in a blink of an eye, three hours of effort have passed.

Zhan Wuque activated the strange fire with all his strength. After three hours of refining, Yunni finally changed a little.

This is the difference between top refining materials.

Even if you want to refine it, it is not easy.

In a blink of an eye, a day and a night passed.

Looking at the Jiuzhou Ding, the cloud mud has changed from the size of a bean to a ball of flowing liquid.

Zhan Wuque had a cautious look on his face, his palms became a knife, and when the void was slashed, the liquid suddenly split into two.

Then, he took out the Yin-Yang Knife and the Star Core.

The Yin-Yang Sword is the strongest weapon he has refined since his rebirth.

And the star core, to be precise, was not refined by him.

The star core is the product left over from a planet's collapse. It has six sides and looks like a brick.

Zhan Wuque just carved the path of hell on one side of the star core.

The star core energy is not destroyed after the planet collapses, which itself shows that its hardness is definitely no less than that of a magical weapon, or even stronger.

But to be on the safe side, Zhan Wuque decided to refine half of the cloud mud into the star core, so that even if the star core is broken, it can recover as before.

Zhan Wuque pointed his fingers, and half of them flew up, gradually covering the surface of the star core.

Zhan Wuque was fully focused and integrated the clouds into the star core bit by bit.

This process lasted for more than an hour.

In the end, clouds were completely integrated into the star core.

Zhan Wuque stopped slowly and keenly felt that a slight change seemed to have occurred in the star core.

Put away the star core, Zhan Wuque looked at the Yin-Yang Knife that was placed aside.

The amount of cloud mud is limited, and only two pieces can be melted at most.

Star core, about the "Six Paths of Reincarnation" he practiced.

The Yin-Yang Knife is his main weapon.

Although the Yin-Yang Sword is only at the Earth level now, Zhan Wuque can use refining materials to continuously refine it in the future. It is not difficult for Tianji and Holy Soldiers to be.

Zhan Wuque stretched out his right hand and held the void, as if he had held the remaining half of Yun Ni in his hand, and then he slapped it on the Yin-Yang Knife's blade.

From the handle, extend to the tip of the knife.

Zhan Wuque closed his eyes and refined with all his strength.

At this time, what Zhan Wuque didn't know was that the door of the secret room was already full of people.

"The secret land is about to begin, why haven't Brother Zhan come out yet? Has he forgotten?"

Princess Wen Yao said, with a look of anxiety on her face.

"No, I want to go in!"

As he said that, Princess Wen Yao would forcefully break the ban.

"etc!"

An Lan was also there, immediately blocking in front of Wen Yao.

"Princess, you can't go in. My uncle said before he went into seclusion. During the seclusion, even if something big happens, you can't disturb him!"

An Landao.

"I know the princess is anxious, but there is still some time left, so let's wait."

An Lan was a little helpless.

"Since that's the case, then okay."

Princess Wen Yao had no choice but to agree.

"Master, why are you here?"

At this moment, Yichenzi also came.

"How is it, haven't the junior brother come out yet?"

Yichenzi asked.

"No," An Lan shook her head.

"My junior brother may be refining those two balls of demon fire," Yi Chenzi said. Not long ago, the Yuwen family apologized to Zhan Wuque, among which there were two balls of sixth-level demon fire.

I think my junior brother must be unable to wait, so he suddenly went into seclusion.

"Ah, what should I do?"

Wen Yao said anxiously.

Refining demon fire is a troublesome thing.

Even if it is fast, it will take ten days and half a month, and it will take two or three months.

If you calculate this, wouldn’t it mean that Zhan Wuque will take a long time to come out? Not to mention the secret place, I’m afraid that the small martial arts stele will have been opened.
