As lowett said before, mana is impregnated.

The mana produced by spiritual power work, no matter what type of spell appears, is essentially the caster's interference with reality with soul energy.

Human discharge of sewage will pollute the environment, and the same is true when casting spells.

Those mana afterwaves mixed with the mage's own soul energy will not simply dissipate with the end of casting. The decomposition and self purification of nature has the lowest residual efficiency on the power of the soul. The more the land with dense casting, the more serious the infection phenomenon will be.

Fortunately, compared with the real sewage pollution, mana immersion will not deteriorate the environmental quality.

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

How else can we do college teaching?

We're all breathing PM2.5.

But

This is only for the mages themselves.

The human body is fragile. In fact, most creatures in nature are vulnerable to spells.

Evolutionary history makes them adapt to the natural environment, and the element concentration they can bear is limited. Artificial casting leads to the increase of density, which is not beneficial but harmful to most organisms.

The most common harm is the sudden increase in element density, which will forcibly stimulate the potential of the body. In order to adapt to the bad environment, the combination of the two phases often leads to variation in the body.

Mage circles call this phenomenon "demonization".

Magic alienation!

Not a demon.

It is well known that the devil is a brother in front of the mage.

In the last invasion, their civilization history, their power system, the resources and specialties of the demon world, and other valuable things were all eaten and wiped away by the mage, especially the necromancer school, which led this desperate plan.

It's said that later, several masters of the dead spirit world accepted the conditions put forward by the demon lord and jointly took measures to shelter them from the wind and rain, so they didn't be exterminated at one time.

But what's the good news?

Obviously, he is free to invade, fight and plunder everywhere. Now he can only be a dog under the command of the masters.

The book belongs to the true story.

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

Well, it depends on what kind of spell it is.

Most spells, whether attacking or healing, are essentially scum men. They only enter your body, not your life.

Especially for healing spells, the mage can't let all residues dissipate, but he also knows the harm of residual mana. He will take it out of the target and throw it into the dustbin.

And flesh and blood magic and flesh and blood suture happen not to be in this range.

After a year of healing, the spell continues to take effect, affecting Nami's body and soul all the time.

Originally, if this is only the case, the side effects will not be too obvious. Regardless of dose and toxicity, it is playing hooligans. No matter how fragile the human body is in the face of magic, it depends on how much "toxin" remains.

However, as she gets closer to the new world and the black count, this residual "toxin" is supplemented by the soul network like a node, causing energy resonance and making the side effects more clear.

"Sure enough, does it have anything to do with him?"

Nami could not stop trembling and clenched her lower lip.

In fact, after entering the great route, she found that she was more sensitive to the air flow. Sometimes she could even capture the moving track of the air flow and respond in advance.

But it's not really "seeing", it's just a mysterious and mysterious perception.

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

But as she continued to go deep into the great route, especially after reaching the dead island sea covered by Skynet, she found that she could perceive more and more things.

In the quiet night, whispers always ring in my ears, disturbing people's dreams.

See the rudiment of color hegemony!

This is what Robin told two women when they were talking.

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

Until today!

The faint green light like emerald became clearer and clearer in Nami's eyes, even if it was covered by her hands. Luffy and his party looked at her in surprise and worried.

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

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

Nami looked up in fear, then her pupils tightened.

Because she found that the dark night was now shrouded in a strange light. She could not see her fingers in the distance, but everything could be clearly seen in her own eyes.

She, once again, aroused energy resonance.

Combined with their own will, the ability of night vision was born!

Lowett doesn't have time to confirm the location of nodes one by one. Anyway, he is the only mage in the world. All targets enjoying his residual energy can access the soul network.

By coincidence, Nami had a mutation.

"Relax, Miss Nami."

At this time, Franks said with a smile, "it's not what the master did to you. In fact, if we hadn't learned the order of the five old stars this time, we wouldn't even know that there was a mutation in you."

Then he looked at Luffy: "talk about the details later. The straw hat is in charge."

"We don't want to compete with the five old stars now. If we want to go and stay, please give us an answer."

Hearing the speech, Luffy 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. In a strict sense, the black count was his biggest enemy!

"SA, who knows?"

Franks shook his head. "We can figure out what the master thinks."

"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 erase your existence, we won't let him do what they want to do, that's all."

Sauron's eyelids jumped: "it's really what the sea owl is qualified to say!"

That's the world government!

Even the arrogant pirate "Captain" Kidd who fought between xiangbodi and Luffy ran away with his tail. Who dares to stop what they want to do?!

however.

On second thought, Sauron figured it out.

At present, the new world is only dominated by the black beast Federation. The rulers of the sea see that they will only compete among the three parties. At this time, the world government is in a decline that has never been seen in 800 years. The pirates are powerful, so naturally they will not miss this good opportunity.

"What do you do, Luffy?"

Sauron won't be afraid to fight, but the decision is in the hands of the captain.

Count black killed shanks and Saab, and executed ace for Karp in public execution. Do you want to accept the help of the enemy?

……

New world, country of peace, capital of flowers.

"Lord Black Carbon snake and Lord kaiduo are back!"

"Lord snake, look here, look here!"

As soon as I entered the flower capital, the noise filled my ears.

The prestige of black carbon snake in the country of harmony is almost concentrated in the capital of flowers. People here admire him very much, whether out of fear, admiration or profit.

The tense nerves finally relaxed. The black carbon snake laughed and waved to the crowd.

Crazy dead Lang narrowed his eyes and looked at the scene, his heart was desolate.

"Ordinary people are foolish. Whoever can make them live better is a wise leader."

"But they clearly know that such a good day is based on the premise that the Arsenal oppresses others. It's none of their own business and they don't care."

"That's why we can't give up hope!"

Holding a white porcelain wine cup, crazy dead Lang looked, and behind him ushered in Xiaozi, the Huakui with the greatest cheers.

There were some things I couldn't do outside, but when I returned to the flower capital, the situation was different.
