"What's the matter with those magic patterns on the wings of the Demon Butterfly?!"

As usual, Zhang Yu activated the Demon Thought Butterfly hidden in the depths of his heart, and directly entered the magical dream space in the form of a spiritual mind body, and as soon as he entered, Zhang Yu was shocked to find that the Demon Thought Butterfly floating in mid-air had actually undergone an abnormality.

I saw that the right wing of the huge demonic butterfly appeared one after another mystical and complex magic patterns, and if I looked closely, it actually echoed his demonized right arm.

"What the hell is going on?Could it be that the reason why I was able to stimulate demonic evil energy also has a lot to do with the Demon Mind Butterfly?!" Zhang Yu's body was shocked, and his face was full of surprise.

Originally, he thought that the reason why he was able to stimulate demonic evil energy was the result of extreme strengthening, but now it seems that it is not all because of this, and it seems to be inseparable from the Demon Mind Butterfly.

There is even a possibility that the Demon Butterfly quietly dominated all this, otherwise, it really can't explain why the Demon Butterfly's wings have exactly the same magic pattern as his.

Taking a deep breath, Zhang Yu forced himself to regain his composure, and after thinking about it seriously, he couldn't help but chuckle out loud, finding that he was a little too troubled.

It is true that the demonic evil ability he stimulated is very evil, completely different from the demonic ability in his cognition, especially after it is completely activated, it is quietly changing his body, and the blessings and disasters are unpredictable, but so what?

There is also the mutation of the Demon Butterfly, which seems to be completely unexplainable by common sense, and it is difficult to judge what kind of mutation will appear next, but what does it matter?

The important thing is to live!

And no matter what the truth is, Zhang Yu only cares about one thing, that is, whether he can enhance his strength so that he can continue to survive, this is the most practical and important.

As for other things, after Zhang Yu thought hard to no avail, he simply cut through the mess and put it aside for the time being, which is the same as his rebirth and the sudden outbreak of the apocalyptic catastrophe, no one knows what is going on, it is useless to think about it, the key is to adapt as soon as possible, and then try to survive.

"Anyway, it's a person who has died once, why do you care so much?!" Zhang Yu chuckled and shook his head, quickly adjusted his mentality, and instead focused on the most practical problems.

In his previous life, he was betrayed and hung up by the people around him not long after he got the Demon Butterfly, just studying some of the basic functions of the Demon Butterfly, and did not have time to study it in depth, and because the evil energy he inspired in his previous life was not demonic evil energy, some things did not have much reference value.

In this life, especially now after discovering the mutation of the Demon Mind Butterfly, Zhang Yu felt that it was necessary to study the Demon Mind Butterfly carefully.

"Maybe you can try to stimulate demonic evil energy in the fantasy dream space!" Zhang Yu's eyes flickered, and he faintly felt that this was probably the key to it, after all, it was after he completely activated the power of demonic evil energy that he caused a series of abnormalities in his body and the demon thought butterfly.

The dream space is really magical and mysterious, although it is in the form of a spiritual mind body, Zhang Yu still successfully stimulated the demonic evil energy, and the entire right arm suddenly demonized and rose to a raging purple flame, and as he guessed, as he urged the power of the demonic evil energy to the extreme, the huge demon butterfly floating in mid-air should be its pair of eyes burst out with an incomparably strange blue light, forming a pillar of light, which completely enveloped him on the ground at once.

"Enchant!"

While being shrouded by that demonic blue light pillar, Zhang Yu suddenly had an extra piece of mysterious information in his mind, and after digesting and absorbing it, Zhang Yu was pleasantly surprised to find that this was actually a secret technique, which could allow him to further stimulate the power of demonic evil energy.

For example, his Flame Sword, although it is accompanied by corrosive flames, has limited power, and it is basically difficult to cause any effective damage when encountering a strong person like Xie Dong or Li Yu, but with the Enchantment Secret Technique, he can attach the demonic evil energy that is excited to the Flame Knife, which greatly increases the power of the Flame Knife.

Not only that, after mastering this enchantment secret technique, Zhang Yu's control and cognition of demonic evil abilities have also been greatly enhanced, and he has entered a new level.

Zhang Yu was very excited, although the enchantment secret technique is only an extension of the demonic evil ability, not a new ability, but this is a good start, and in the long run, since there is an enchantment secret skill, then there must be other secret skills, if you can comprehend and control it, then these will become his killer skills.

Zhang Yu, who has passed through rebirth, knows very well what these mean, and has added confidence to survive in this terrifying apocalypse.

"In addition to enchantment, are there any other secret techniques?!" Zhang Yu's eyes lit up, and he continued to frantically urge the demonic evil energy, wanting to explore further, but this time, he did not arouse the resonance of the demon butterfly, but was directly expelled from the dream space.

After "Click!! returned to the world, Zhang Yu had just opened his eyes, and he heard a series of subtle and crisp cracking sounds, looked down, and couldn't help but be stunned to find that the blood crystals in his waist bag had all turned into powder and were completely scrapped.

"Three fifth-order red crystals, twelve fourth-order red crystals, and hundreds of third-order red crystals, all of them are gone all at once?!" Zhang Yu was a little painful, and at the same time, he also reacted, if he didn't guess wrong, the process of triggering the resonance of the Demon Butterfly and obtaining the secret technique before should have consumed extremely amazing blood crystal energy, so that all the loot he had collected before was gone.

However, after the pain in the flesh, Zhang Yu quickly chuckled, although the loot was gone, but with the enchantment secret skill, his combat effectiveness was greatly improved, and he could naturally get more loot.

"Yuzi, you're in a good mood, isn't this meditation very rewarding?" Xiao Hua, who was in charge of helping to protect the Fa, couldn't help but ask.

"It's really rewarding, originally I was a little hesitant about this trip to Civic Square, not sure if I could successfully achieve my goal, but now I'm a little sure!" Zhang Yu's eyes flashed and he stood up.

Noticing that Zhang Chengzhong and the others had basically recovered after some treatment and recuperation, Zhang Yu directly waved his hand and set off again.

They had already driven a long distance before entering the underground waterway, and the route that Ah Fei had guided almost reached the bottom of the Civic Square, so as long as they kept moving at their current speed, they had every hope of reaching the Civic Square before dark.
