Mortal blood!

Cui Yu could refine the Xiao Sancai Gathering Spirit Array, so his attainments in the formation were naturally good.

The formation he refined himself could be sold for at least 10,000 low-grade spirit stones.

In addition, there were a large number of defective origin powers that could be taken away for free.

At this moment, Lin Fan was already very happy in his heart, but on the surface he pretended to be very embarrassed.

"You really make it difficult for me. I use those defective origin powers to practice, and the effect is minimal."

"As for the formation... I think at least two sets are needed, how about it?"

Lin Fan said calmly.

"Haha, I knew that Fellow Daoist Lin is a smart person and will never refuse such a good thing. If so, Fellow Daoist, come with me."

Cui Yu was ecstatic and agreed without hesitation.

As he spoke, he took Lin Fan into a small courtyard behind the wine shop.

The small courtyard was only more than ten feet in size.

But there was a different world inside.

There were fake mountains and fake waters, flowers, birds, fish and insects.

In addition, there was a crow-like monster in the foundation-building period, which was about the size of a foot and exuded the breath of ice and fire. It was sitting on a big tree as thick as a bowl, combing its feathers constantly.

Even though it saw Lin Fan and Cui Yu coming in, it ignored them.

"Lihuo Jackdaw?"

Lin Fan's eyes swept over the monster and he was immediately surprised.

Lihuo Jackdaw!

This is the only monster among monsters that can use both ice and fire attributes.

Every Lihuo Jackdaw is born in the early stage of foundation-building.

It has a fire attribute magical power, which is even more powerful.

If an ordinary cultivator in the early stage of foundation-building encounters a Lihuo Jackdaw, even in a one-on-one situation, he can only flee.

"Friend Lin Daoyou has good eyesight. This Lihuo Jackdaw is a monster raised by our Cui family. It has an extremely gentle temperament and is of great help to me in refining formations." Cui Yu explained with a smile.

"I only know that to refine the formation, you need the slow fire of the immortal cultivator. It's the first time I've heard of using the demon fire to refine the formation." Lin Fan was surprised.

Cui Yu didn't explain this.

After letting Lin Fan wait in the yard, he went straight into a secret room.

I don't know what Cui Yu was busy with. He fiddled with it for an hour before he walked out of the secret room a little tired.

"Fellow Daoist Lin, everything is ready. Please follow me."

Lin Fan nodded.

He followed Cui Yu into the secret room.

Boom!

A harsh sound came from the secret room.

I saw that a gray formation light curtain had been completely opened, covering the entire secret room.

Lin Fan looked normal, but he was very alert in his heart.

Cui Yu's expression remained the same.

He took Lin Fan to a piece of warm sun gemstone about ten feet in the center of the secret room.

"Fellow Daoist Lin, I need to place the eye of the array in this piece of Warm Sun Jade later. You just need to tell me the location of the eye of the array." Cui Yu said solemnly.

Lin Fan nodded seriously: "I will naturally do my best."

"Thank you!"

Cui Yu's face lit up.

The next moment, he waved his hand, and a buzzing sound suddenly came from the secret room.

Then, a series of light beams as thick as the mouth of a bowl suddenly emerged from all around the secret room.

Bang bang, one after another fell on the Warm Sun Jade.

Lin Fan naturally couldn't understand what these light beams were for.

But at this time, Cui Yu's expression became extremely serious.

Carefully took out a thumb-sized round bead and pressed it into the Warm Sun Jade.

"I need to place the eye of the array in the middle of this Warm Sun Jade, and there can't be any mistakes. Otherwise, all the previous efforts will be wasted." Cui Yu said.

"Got it!"

Lin Fan agreed, seemingly normal, but a little nervous in his heart.

With a thought, the clear and bright eyes started to work instantly.

Instantly, the round bead that Cui Yu put into the Nuanyang Gem was locked by Lin Fan.

At this moment, the position of the round bead was slightly lower and right of the Nuanyang Gem.

"Fellow Daoist Cui, move three inches and three centimeters to the upper left."

"Okay!"

Cui Yu agreed and did it immediately.

Lin Fan looked at it carefully for a while and found that the position of the round bead was still a little off.

Under his command, Cui Yu adjusted it several times, and the eye of the formation was finally placed in the center of the Nuanyang Gem.

"Okay!"

Lin Fan nodded.

Cui Yu heard it and immediately let go of his hand.

Boom!

The light column that fell on the Nuanyang Gem dispersed instantly.

Not long after, strange green lights appeared on the surface of the Nuanyang Gem. Just like the meridians in the body of a cultivator, there was actually spiritual power running on its own.

Seeing this, Cui Yu looked ecstatic.

"Haha, thank you, Fellow Daoist Lin. The problem of placing the eye of the formation has finally been solved."

"Congratulations, Fellow Daoist Cui. If so, you should also fulfill your promise to give me the defective original power and the formation, right?"

"Fellow Daoist Lin is really impatient. Just follow me."

Cui Yu smiled slightly.

After leaving the secret room with Lin Fan, he came directly to the Lihuo Jackdaw.

It is unknown what method Cui Yu used, but the Lihuo Jackdaw, which was combing its feathers, suddenly screamed three times.

In an instant, the protective formation light curtain in the courtyard disappeared rapidly.

A huge pool of water several feet in size and ten feet deep appeared in front of Lin Fan.

In the pool, there was actually a pool of emerald green defective original power.

This kind of generosity made Lin Fan secretly ecstatic.

"If I use the mysterious copper bottle to purify all of these defective origin powers, it will be enough to upgrade the level of "Five Elements Chaos Sword Art" to the top grade, right?" Lin Fan thought to himself.

Cui Yu saw Lin Fan standing in front of the defective origin power for a long time without saying anything, and immediately smiled and said: "You can take all these defective origin powers away."

"Thank you!"

Lin Fan thanked him and quickly took out a bunch of palm-sized jade bottles and patiently filled them up.

Only after waiting for two hours, Lin Fan collected all the origin powers without dropping a drop.

Cui Yu didn't say much.

With a wave of his hand, dozens of array plates with flashing spiritual light floated in front of Lin Fan.

"Fellow Daoist Lin, these array plates for arranging the formations are all made by me. You can choose two sets from them."

Lin Fan's divine consciousness quickly swept across the array plates in front of him.

It was found that the spiritual power fluctuations on these array plates were almost the same.

It is simply not feasible to judge the power of the formation from the fluctuation of spiritual power.

However, Lin Fan was not in a hurry.

His clear and bright spiritual eyes were secretly activated, and after careful observation for a while, he quickly locked onto two sets of formation plates.

"That's them!"

Lin Fan waved his hand casually, and the two sets of formation plates fell into his hands.

Cui Yu saw this and immediately felt a pain on his face. There was a chill in his voice.

"Fellow Daoist Lin is really amazing. The ones he picked are all the fine formations I refined."

"If these two formations were put on sale outside, each set would be worth more than 100,000 low-grade spirit stones."

Lin Fan seemed to be normal, but deep down he was extremely alert.

"What do you mean by this? Are you planning to regret it?"
