Mortal blood!

"Is this true?"

Lin Fan couldn't believe it.

After all, the Third Eye of the Third Eye Demon King is the essence of the Third Eye Demon King.

If just a simple refining process could increase the power of his clear spiritual eyes, this would be a great opportunity.

"Master, how dare I lie to you about this kind of thing? If you don't believe it, try refining it now." Shuhun explained.

"Um!"

Lin Fan nodded, and with a wave of his hand, he sent the book soul into the book "Self-cultivation of the Book Soul", and then began to meditate to refine the Third Eye.

Buzz!

Lin Fan thought, and the majestic spiritual thoughts were already attached to his third eye.

In the sky, a majestic and powerful force, like a clear spring, slowly seeped into Lin Fan's eyes.

Lin Fan closed his eyes tightly, but suddenly felt that colorful bubbles appeared out of thin air in front of his eyes.

As the time for refining the Third Eye grows longer, there are more and more such bubbles.

In the end, a colorful and weird light curtain was formed.

"this……"

Lin Fan was very curious, but at the critical moment of refining the Third Eye, he did not dare to act rashly.

He suppressed the surprise deep in his heart and continued to refine his Third Eye.

Although the whole process was smooth, it took a full five or six days.

After the Third Eye was completely refined by Lin Fan, the Third Eye itself turned into a pile of white ash, which scattered out of thin air with a crash in the breeze.

At this time, the colorful screen of light in front of Lin Fan also disappeared in an instant.

It seems that after refining the Third Eye, there seems to be no change in the Qingming Spiritual Eye.

"Didn't it work?"

Lin Fan frowned.

But he wasn't in a hurry.

Carefully activate the clear and bright spiritual eyes.

I found that in the cave where I was, the protective formations hidden in the dark were clearly visible in front of my eyes.

He could even easily see through several secret rooms in the Ten Thousand Demons Pavilion.

"The effect of Qingming Spiritual Eyes has indeed increased. And the magnitude should not be small. However, what is the colorful light curtain that just appeared in front of my eyes?"

Lin Fan was curious and tried his best to explore.

I have been busy for a while, but to no avail.

Even the colorful light curtain that disappeared never appeared again.

Only when he thought for a long time, relaxed completely, and stopped obsessing over the colorful light curtains, those colorful light curtains that disappeared unexpectedly appeared again.

Lin Fan was pleasantly surprised and quickly tried to use his mental power to control the colorful light curtain in front of him.

He discovered that these light curtains were like living creatures and could be easily changed under the control of his mental power.

Now Lin Fan was even more curious.

"What is the use of these colorful light curtains? Is it just my hallucination?" Lin Fan thought to himself.

As a cultivator in the early stage of Nascent Soul, he can already be regarded as a strong person in the upper and lower planes.

Although hallucinations may appear occasionally, Lin Fan believes that with his strength, they will never happen so frequently.

After thinking for a long time, when Lin Fan still looked puzzled, he called out the book soul again.

However, this time the book soul just appeared in front of him, and his expression suddenly became blank.

The whole person seemed to disappear out of thin air.

When standing in front of him, she would cry and laugh at other times, as if she had entered some indescribable weird state.

"Book soul!"

Lin Fan was angry and his tone suddenly became more serious.

At this time, Shuhun was suddenly awakened by his voice. Before Shuhun could explain to him, Shuhun seemed to have entered a strange state of crying and laughing for a while.

This made Lin Fan extremely puzzled.

After thinking carefully for a while, Lin Fan suddenly had a flash of inspiration in his mind.

"Could it be that when I activated the Qingming Spiritual Eyes, the colorful light curtain caused the book soul to hallucinate?" Lin Fan asked in surprise.

As he spoke, he quickly calmed down and concentrated. After the colorful light curtain in front of his eyes completely disappeared, Book Soul unexpectedly woke up from his strange state very quickly.

"Master...Master, did you practice illusion just now?" Shuhun asked in surprise.

"Illusion? Is it really the colorful light curtain that is working?"

Lin Fan was extremely curious.

With a thought in his mind, he once again tried to activate his Qingming Spiritual Eyes, triggering a colorful light curtain.

Buzz!

As a colorful light screen appeared in front of Lin Fan's eyes, the book soul actually entered that weird state again.

As more and more colors appeared on the light curtain, Lin Fan moved the light curtain faster and faster.

Lin Fan clearly felt that the consumption of spiritual energy in his Niwan Palace was also accelerating.

"It turns out to be an illusion that can be activated by divine thoughts. Moreover, the strength of divine thoughts seems to determine the strength and duration of the illusion. If it is activated suddenly, it can have unexpected effects."

When Lin Fan thought of this, he felt extremely happy.

After killing the Heavenly Eye Demon King, although he did not find the Heavenly Eye Demon King's storage ring, just this Heavenly Eye was priceless.

"Wake up!"

Lin Fan looked at the book soul and chuckled.

The book soul, trapped in the illusion, suddenly woke up. He looked at Lin Fan awkwardly and said, "Master, it was you who cast the illusion?"

"Well, you just told me that after refining the Third Eye, it has the effect of improving the clarity of the spiritual eye. But you never mentioned that it would allow me to easily control illusions." Lin Fan said.

"This... is probably the illusion of the Demon King Tianmu, controlled by you, master. This is also a great good thing for the master. I would like to congratulate the master first." Shuhun said with a smile.

Lin Fan smiled faintly and put away the book soul with a wave of his hand.

In the following period, Lin Fan continued to study the illusion techniques he had mastered and the use of Qingming Spiritual Eyes, which allowed him to gain a lot in a short period of time.

During this time, Hu Meier finally made an appointment with Hong Tianling, the fourth protector of Hongyu Cave, and asked Lin Fan to come out to meet him.

Lin Fan naturally would not refuse this.

After packing up his things, he left his cave directly.

Not long after, in the hall of Tianyao Pavilion, I saw Hu Meier smiling and communicating with a burly demon woman in the middle stage of Nascent Soul.

Seeing Lin Fan coming over, Hu Meier hurriedly smiled at Lin Fan, and then she explained to the burly demon clan woman: "Protector Hong, this is Taoist Lin who I mentioned to you, and he is also specially for Hong. The son of Patriarch Yu is here to celebrate his birthday."

"oh?"

Hong Tianling looked surprised.

She looked at Lin Fan carefully for a long time, but she didn't know what she saw, but there was a flash of strange color deep in her eyes.

But at this moment, she didn't say much.

After greeting Lin Fan politely, he actually stood there without saying a word.

Seeing this, Hu Meier quickly smoothed things over.

But Hong Tianling didn't seem to give her any face, and kept her face cold, which made Lin Fan more and more puzzled.

After the three of them had an awkward chat over a cup of tea, Hong Tianling suddenly looked at Hu Mei'er: "Mei'er, I want to have a private chat with this fellow Daoist Lin, okay?"

"Ah, that's... no problem!"

Hu Meier nodded, gave Lin Fan a meaningful look before leaving, and left directly.

However, shortly after Hu Meier left, Hong Tianling's face suddenly darkened.

A cold murderous intention suddenly emerged from her body.

"Fellow Daoist Lin, although the demon aura in your body is pure, and you are still practicing our demon clan's famous "Phaseless Physical Training Technique". However, a human monk like you comes to my Ruby Holy City and tries to get close to the master. , but there is another plan?”
