Discharge of sewage by humans will pollute the environment, and the same is true for law enforcement.

Those mana aftermath mixed with the energy of the wizard's own soul will not simply dissipate with the end of the spell. Nature's decomposition and self-purification have the lowest efficiency in the residual power of the soul. The more the land with densely cast spells, the more serious this infiltration phenomenon.

Fortunately, compared with the pollution of the environment by actually discharging sewage, Mana Dipping does not deteriorate the quality of the environment.

On the contrary, after the energy residue provided by the mage is gradually "digested and absorbed" by nature, a quality environment with dense elemental aura is born, which is more conducive to contact with magic.

Otherwise, how can you engage in college-style teaching?

Go to breathe p25.

but……

This is only for the wizards themselves.

The human body is fragile. In fact, most creatures in nature are fragile in the face of spells.

The evolutionary history allows them to adapt to the natural environment, and the concentration of elements they can withstand is limited. The increase in density caused by man-made spells is not only useless, but harmful to most organisms.

The most common harm is the sudden increase in element density, which will forcibly stimulate the body's potential, and in order to adapt to the environment, under the combination of the two, the body often changes.

The wizarding world refers to this phenomenon as "demonization".

Magical alienation!

Not a demon.

Everyone knows that the devil is a younger brother in front of the mage.

The last time they invaded, their civilization history, their power system, the resources and specialties of the demon world, and other valuable things were completely wiped out by the mage, especially the necromantic school that dominates this extinct school, which is the most ruthless.

I heard that later, several masters of the necromantic world accepted the conditions proposed by the demon master and jointly took action to shelter them from the wind and rain, and they were not exterminated at one time.

But what good news is this?

Obviously invading, fighting and plundering freedom everywhere, now I can only be a dog under the command of the masters.

The book is back to the main story.

Since the increase in the element density of the external environment will lead to biological mutation, what will happen to the residual mana in the body?

Well, it depends on the type of spell.

Most spells, whether attacking or healing, are essentially scumbags, only entering your body, not your life.

Especially for healing spells, the mage cannot let all the residues dissipate cleanly, but he also knows the hazards of the mana residues, and will take them out of the target body and throw them into the trash can.

And flesh-and-blood magic and flesh-and-blood stitching just happened to be out of this range.

The healing time lasted for a year, and the spell continued to take effect, affecting Nami's body and soul all the time.

Originally, the side effects would not be too obvious, regardless of the dose and toxicity. The human body is fragile in the face of spells, and it depends on how many "toxins" remain.

But as she got closer and closer to the new world and closer to Earl Black, this remaining "toxin" was supplemented by the soul network like a node, causing energy resonance and making the side effects more clearly visible.

"Sure enough, is it related to him?"

Nami couldn't stop trembling, biting her lower lip.

In fact, after entering the great route, she discovered that she was more sensitive to the airflow, and sometimes she could even catch the movement trajectory of the airflow, and make a starter in advance.

But that is not really "seeing", it is just a mysterious and mysterious perception.

So I didn't care too much, even complacent.

But as she continued to deepen the great route, especially after reaching the Dead Island waters covered by Skynet, she found that she could perceive more and more things.

On a quiet night, there will always be whispers in the ears, disturbing people's dreams.

See and hear the embryonic form of color domineering!

This is what Robin told her when the two women were talking.

Knowing that there was still such a mysterious thing on the sea, Nami felt relieved again.

until today!

The faint emerald green light became clearer and clearer in Nami's eyes. Lu Fei and his party looked at her in surprise, with anxious faces.

"Nami, what's the matter with you?!"

"I... I don't know."

Nami raised her head in horror, and then her pupils tightened.

Because she found that the night that should have been dim was shrouded in a strange light at this moment, and she couldn't see her fingers in the distance, but everything was clearly visible in her own eyes.

She once again caused energy resonance.

Combining his own will, the ability of night vision was born!

Lowett has no time to confirm the location of the nodes one by one, anyway, there is only one mage in this world, and all the targets that enjoy his residual energy can access the soul network.

By coincidence, Nami mutated.

"Relax, Miss Nami."

At this time, Franks said with a smile: "This is not what the master did to you. In fact, if it hadn't been for the order of the five old stars this time, we wouldn't even know that a mutation had occurred in you."

Then looked at Luffy: "Let’s talk about the details, Straw Hat Master."

"We don't want to face up with the five old stars now. If we want to leave, we must stay. Please give us an answer."

Hearing this, Lu Fei turned his head and looked at him seriously: "Why do you want to help us?"

At this time, he already knew a lot of things. Strictly speaking, Earl Black was his greatest enemy!

"Sa, who knows?"

Franks shook his head: "How can the master's idea be contemplated by us."

"But not surprisingly, it's just because everyone has their own position."

"position?"

"Well, that's right."

He smiled: "No matter why the five old stars send killers to obliterate your existence, we will not let him do what they want to do, nothing more."
