Of course, Phil couldn't slaughter a city in order to study the negative energy element, because to do that would already be the act of a dark wizard. If he kills a boatload of people now, he is already on the edge of the bottom line of the First Code of Wizards, although he can completely ignore the First Code of Wizards.

Because he still wants to stay well in the White Wizard area and the Dark Wizard area, he doesn't want to be a dark wizard at all, if someone finds out that he slaughters a city will not violate the first code of wizards, then others will definitely treat him as a dark wizard, whether he is or not. He will even increase his hunting efforts because of his difference from the Dark Wizard.

Besides, slaughtering a city just to study the negative energy element is not worth it, paying too much and gaining too little, it is impossible for him to do such a thing. Maybe that's why he really doesn't want to slaughter the city.

As for Arthur's idea of turning the ship into Dewey City, Phil can only say that he is too naïve, or too worshipful of the negative energy element.

It's like the difference between an eco-box and an eco-park, on the surface, both are man-made, both have elements of the natural ecological environment, and both have a certain ecological balance. However, no one would think that the eco-box would grow to the level of an eco-park.

Because compared with the ecological park, the ecological box needs more high-precision control and care, and if you are not careful, it will lose control, resulting in the ecological imbalance of the entire ecological box. However, it is difficult for ecological parks to have an ecological imbalance unless they are destroyed on a large scale.

The sea ship in front of him is equivalent to an ecological box, and every step of the change is under Phil's control, which is why it will show such a strong negative energy element form, if Phil ignores it, it won't take long for it to collapse. And Dewey City was formed naturally after the dark wizard slaughtered the city, and the whole city has been integrated into the surrounding environment, forming a part of it, and there is no comparison between the two at all.

Of course, if Phil wanted to make the ship exist a little longer, it would not be impossible to do it, but it would take a lot of time and energy, and it would only be a negative energy element, which Phil could not afford.

"Let's get started. ”

Now Phil has spent almost a month and a half to transform the sea ship, which is already the limit of his efforts to study the negative energy element, this is because the books about the negative energy element are very rare, and it is difficult to understand unless you see it with your own eyes, otherwise, Phil would have searched for these books instead of staying here to make some "miniature Duwei City", after all, reading books and a little experiment can fully understand it in a month at most, instead of wasting so much time like now.

Arthur also probably understood what Phil meant, didn't say anything, flew into the air, came to the front of the sea ship, and stopped about a hundred meters away from the sea ship, this is the best position, go a little further, it may be affected by the strong negative energy element, or it will destroy the negative energy element force field that is faintly formed naturally by the entire sea ship.

He began to carve a large wizarding array in mid-air, and Phil flew to his side, taking a closer look.

Soon, the sorcery array was completed, and Arthur began to push it forward, as if he had blended in, completely unaffected.

There was a hint of interest in Phil's eyes.

Arthur walked slowly, and soon came to the position of the bow of the ship, I don't know why, there is obviously no one dead here, but it has formed a node of the negative energy elemental force field, which shows that for these people on the ship, this is a place they are very afraid of, and it just so happens that this is where Arthur fed the fish before.

Arthur used this node as a starting point and began to pull the nearby negative energy elemental force field. Countless black smoke gathered towards him as if it were substance, pouring into the wizarding array in front of him, and after a series of changes, poured into his body.

Phil could see that after a period of time, a layer of hazy black began to appear on Arthur's body, the more time passed, the more intense the black became, slowly, this layer of black gradually expanded, and suddenly seemed to have reached a certain limit, the black suddenly shook, and suddenly transformed into a black shadow more than three meters high and appeared behind Arthur, it was a strange black shadow, a huge head, slender arms, and a face that could not be seen clearly, very similar to those yin entities produced in a special environment.

But it's definitely not.

As soon as the black shadow appeared, it immediately accelerated the speed of absorbing negative energy elements, and the entire sea ship gradually faded with the naked eye, and after a while, it completely disappeared on the sea surface, as if the sea ship before that was condensed by these black shadows, and the black shadow behind Arthur had almost condensed into substance.

Phil watched with interest the change, a marvelous discovery, and worth the time he had wasted. Why is there such a change, but the sea ship is obviously a real object, but now it has become a virtual creation and disappeared, and how is the process of change realized...... Phil had a myriad of questions for a moment.

This caused him to ignore Arthur for a moment.

During this period of time, the black shadow behind Arthur gradually merged with him, and the aura on his body also increased little by little, from the early stage of the second-level wizard, slowly growing to the middle stage, and then growing to the late stage, and now he is now at the peak of the second-level wizard.

This finally caught Phil's attention, and when he looked at it, a black shadow appeared behind Arthur again, and now, that black shadow was no longer black, but completely like Arthur's appearance, but it was darker, and the negative energy elemental aura emitted couldn't help but make people feel frightened.

The negative energy element, which is originally a collection of negative energy such as fear, resentment, and greed, once it reaches a certain level, will exude an emotional force field to nearby people and affect the emotions of others.

And when the negative energy element forms witchcraft, the emotional force field caused will have a powerful attack ability.

"Roar—"

Arthur suddenly roared and turned to look at Phil.

His whole body aura has changed now, and his eyes are blank, but the phantom behind him showed a strong tyrannical expression, and with a roar, the sky around him suddenly darkened, as if some terrifying Great Demon King had appeared.

"Interesting. Phil chuckled softly, "Now, it should be the level of the early stage of a third-level wizard, right?"

The aura that Arthur exudes now is indeed the level of the early stage of a third-level wizard, but he has completely lost consciousness, as if he has been affected by negative energy elements.

He suddenly flashed, and the whole person disappeared in place, and when he reappeared, he had already appeared ten meters in front of Phil.

The black smoke condensed and turned into a huge terrifying head, attacking Phil.

"Pu. ”

A string of fluorescent glows with black glows appeared, converging in front of Phil to form a pu.

Pu Qiao laughed, stretched out his hand and pointed forward, a faint red light flashed on his finger, and a powerful force slammed into the huge and terrifying head.

"Boom!"
