In the more than twenty days of comprehending the mystery of annihilation, Mu Yan also had a deeper understanding of the dark energy.

When leaving, a flash of inspiration suddenly appeared, and it was normal to faintly touch another mystery in the dark law.

"Shadow Mysteries ......"

"This is also a six-grade mystery, which has a strong auxiliary effect. ”

"Once you comprehend the mysteries of the shadows, in the shadows, your combat effectiveness can be slightly improved!"

"In addition, in the shadows, you can hide yourself better!"

Mu Yan said secretly in his heart.

Without any hesitation, Mu Yan sat directly cross-legged at this time.

Continue to stay on top of this cliff of annihilation and comprehend the mysteries of the shadows of the dark system!

The more mysteries, the better, especially for Mu Yan, the more mysteries he comprehends, the easier it will be to integrate the mysteries and improve the comprehension of the mysteries. Now that he has touched the threshold of the shadow mystery, he naturally wants to stay here and comprehend the shadow mystery successfully.

Time passes slowly.

One day...... Two days...... Three days......

It's just three days later, Mu Yan has successfully comprehended the prototype of the shadow mystery!

"Normally, since I have comprehended the rudiments of the shadow mysteries, then, in a few days at most, or at least three or five days, I should be able to successfully comprehend the shadow mysteries. Mu Yan said secretly.

Calming down, Mu Yan continued to comprehend.

In the blink of an eye, five days passed.

The shadow is mysterious, and the comprehension is not successful.

Ten days have passed!

What surprised Mu Yan a little was that this shadow mystery, he still didn't succeed in comprehending it!

Fifteen days have passed!

Shadow Mystery, I still haven't been able to comprehend it successfully!

"What the hell is going on?"

"Could it be...... I have comprehended the mystery of the shadows, and I have entered a certain misunderstanding?"

Mu Yan simply stopped, stood on top of the Annihilation Cliff, waited for dusk, the sunset to come, and carefully observed the shadows on the Annihilation Cliff.

Dusk came soon, it was already winter at this time, although it was only sunset, but the sun shining on Mu Yan's body still made Mu Yan feel a little warm.

On the other side of the cliff of annihilation, there is still no sunlight and only shadows because of the mountain peaks.

"Shadows...... Shadow ......"

"Where there is light, there is shadow! Without light, there is no shadow......"

"The mystery of shadows is not only related to the dark system, but also related to the light system. If you don't have a certain understanding of the light system, you can't comprehend the mystery of shadows at all. ”

Mu Yan's heart moved and he came to such a conclusion.

Before, I only realized the darkness, and I didn't realize the light at all!

And only the combination of light and darkness can comprehend the mystery of shadows.

After figuring it out, Mu Yan was extremely happy, and immediately sat down cross-legged again and comprehended it again.

Mu Yan also has a strong talent in the light system, and he has even already comprehended the illusion mystery of the light system.

Now it is not difficult for Mu Yan to combine the laws of light and darkness and comprehend the mysteries of shadows.

This time, another five days passed.

"Shadow Mystery, I see!"

"I have truly comprehended this shadow mystery!"

Mu Yan, who originally had his eyes slightly closed, suddenly opened his eyes, and an incomparably sharp light shot out of his eyes.

It took a total of twenty days for Mu Yan to finally comprehend the mystery of the shadow.

This speed is not too fast, after all, Mu Yan has taken some detours in the process of comprehending the mystery of the shadow. However, compared to any super genius, Mu Yan's speed of comprehending the mysteries of the shadows was definitely not slow. In twenty days, he was able to comprehend a mystery, except for those "luck warriors" who relied on epiphany and instantly comprehended a certain mystery, Mu Yan's comprehension speed was already an incomparably terrifying existence in normal comprehension.

After comprehending the mysteries of the shadows, Mu Yan did not leave the Cliff of Annihilation immediately, but continued to stay here.

Because......

At this time, Mu Yan is ready to do one more thing!

Combine the mystery of shadows with the illusion mystery of the light system!

In the past twenty days of comprehension, Mu Yan not only comprehended the shadow mystery, but also discovered a certain connection between the shadow mysteries and the laws of the light system.

As early as a few months ago, Mu Yan had already comprehended the illusion mystery of the light system.

Now that you have comprehended the mysteries of the shadows, you will immediately fuse these two mysteries to form a higher level of powerful mysteries!

"Shadow mysteries, fuse illusion mysteries, and eventually be able to form 'phantom mysteries', this mysteries should be at the level of four grades!"

"It's the same as destroying the mysteries!"

Mu Yan said secretly in his heart.

The mysteries of light and darkness at the eight-grade level are fused together to form the mysteries of light and darkness at the five-grade level.

At present, Yang Qian has comprehended the mysteries of light and darkness.

And the six-grade level phantom mysteries and illusion mysteries, after fusion, can form a more powerful, four-grade level phantom mysteries!

This is a powerful auxiliary occult class.

Comprehend the mysteries of phantoms, and between the journeys, the body turns into a phantom, which can hide its traces to the greatest extent.

Especially when it travels in the shadows, it has the ability to be almost invisible.

Once Mu Yan comprehends the Phantom Mystery, when fighting, he can use the Four Grades to destroy the Mystery, and in a non-combat state, he can use the Phantom Mysteries to hide his tracks. At that time, Mu Yan's strength would become extremely terrifying.

In the future, even if Mu Yan can't comprehend other mysteries, and only relies on the two four-grade mysteries of phantom mysteries and destruction mysteries, after becoming holy, these two mysteries will be comprehended to a 100% state, and Mu Yan's strength may not be as good as Xiao Ling, who comprehends the mysteries of killing and the mysteries of the mausoleum, but it will not be too different.

Fusion Xuanmy, although Mu Yan has found the trick, but it is not easy.

It takes time, and it takes longer than comprehending the mysteries.

A full month passed.

Mu Yan, who was sitting cross-legged and comprehending, opened his eyes, and his eyes shot out of an extremely excited light.

"Phantom Mystery, finally the fusion has been successful!"

"With the Phantom Mystery, my ability to hide my whereabouts has been greatly improved, and when I travel in this dark forest, even if I accidentally encounter a strong man of the Praetorian Guard of the Great Yang Empire, I can immediately find a way to hide it. ”

"Even if it is a powerhouse of the Eight Heavens and Nine Heavens level, as long as they don't get close to within five hundred meters around them, it will be difficult for them to find my traces!"

Mu Yan comprehended the mysteries of the phantom at this time, and he was more confident.

"First improve the comprehension of the phantom mystery!"

Mu Yan said secretly.

If you want to continue to integrate it with other mysteries, then it is best not to improve your comprehension.

One percent comprehension, the easiest to integrate.

But if you are not ready to fuse, then improve your comprehension, make this mystic stronger, and use it directly.

For example, the destruction mysteries comprehended by Mu Yan need to continue to merge with the annihilation mysteries, so now the comprehension has not been improved, and the comprehension is still one percent.

Phantom Occult is different.

This mystery, although it is also a fourth-grade level, has no potential to continue to fuse.

It can no longer be fused with other mysteries to form a stronger mystery.

Therefore, Mu Yan decided to directly improve its comprehension and directly use this mysteries to improve his strength.
