Chapter 170

【Black Natsu nodded.】

【"However, this is also normal, I've been doing this for almost this whole month."】

【"At that time, in order to increase a large amount of magic power in a short time, I had to choose to eat the Lightning Dragon's lightning."】

【"However, the side effects of such an action are also very obvious. Not to mention the rejection problem, the magic power swallowed that day was really too much."】

【"Such powerful magic power was something my body couldn't bear, so I poured out a part of it through battle."】

【"And the remaining part gradually took root and sprouted in my body, and this power would instinctively want to destroy the original magic source in my body and then replace it."】

【"So, what you did was to purge these rebellious forces?"】

【Irene seemed to understand something.】

【"It's not like that, you can understand it as assimilation," Natsu said.】

【"Completely assimilating this power that didn't belong to me into my power. Of course, there are also steps to expel the dross, so the absorbed power is gradually decaying."】

【"There isn't much left, so I said the power is much smaller than it was then, but it's also several times stronger than before I ate the lightning, and furthermore..."】

【Speaking of this, Black Natsu raised his arm, and crimson-black lightning began to flash crazily!】

【Irene's pupils shrank!】

【"You really turned this power into your own?"】

【Black Natsu smiled, then put away the crimson-black lightning.】

【Then his expression became serious, and he continued.】

【"However, in this process, I discovered another problem."】

【Looking at Irene's confused eyes, Black Natsu said in a deep voice.】

【"Dragonification! Overusing Dragon Slayer Magic will lead to an increase in one's own dragonification."】

【"You... have you already realized it?"】

【Irene's expression also became heavy; this is not only a problem that troubles Natsu, but also a problem that troubles Irene herself.】

【Yes, she had told Igneel before that she had already started to turn into a dragon, and it was precisely because of this that she had a lifespan comparable to a dragon.】

【Hundreds of years, thousands of years are not a problem.】

【It sounds like a good thing, but in fact, it is the opposite.】

【In the process of dragonification, your humanity will also be gradually annihilated, until finally you completely become a monster that only knows how to kill.】

【This is something Irene only discovered recently, but because the consequences were a bit serious, Irene didn't tell Black Natsu.】

【I just didn't expect that he himself realized the changes that happened to his body.】

【Looking at Irene's appearance, Black Natsu also understood that she knew very well the consequences of dragonification.】

【"This is a troublesome problem."】

【"However, it's not that there's no solution."】

【"Eh?!!"】 Listening to Black Natsu's words, Irene was startled!】

【Her gaze was fixed on Black Natsu in front of her.】

Even Irene outside the screen had an expression of disbelief on her face.

"There's a way? What kind of joke is this? If there really was a way... then I wouldn't have been troubled for over four hundred years, and only recovered to normal today with the help of the screen, okay?"】

Irene couldn't imagine in her dreams what could solve the problem of Dragon Slayer dragonification.

So, her gaze was fixed on the screen.】

【"Actually, this is just my guess."】

【Facing Irene's burning gaze, Black Natsu twitched his lips, then spoke.】

【"The root of dragonification is that the seed of Dragon Slayer Magic takes root and sprouts in the body, let's call it the Dragon Seed for now."】

【"Once the Dragon Seed starts to sprout, it proves that you have started to turn into a dragon."】

【"This degree will grow with the gradual use of Dragon Slayer Magic, and the branches will grow into the limbs and bones."】

【Speaking of this, Black Natsu paused slightly.】

【Then he looked at Irene: "Of course, this is just my metaphor, you just need to understand it, the actual operation will be a thousand times, ten thousand times more complex than this."】

【"The growth of the branches can be understood as the spread of dragon power. When dragon power erodes the whole body, a person will completely turn into a dragon."】

【"I think that Acnologia, who exists in legends, is in this situation; the dragon power, or rather, the branches of the Dragon Seed, have already occupied half of his body."】

【"So, how exactly should we avoid this situation?" Irene was a bit confused.】

【"This might just be my hypothesis, I haven't really tested it."】

【Natsu patted his full stomach, then said his guess.】

【"Perhaps, we can refer to the source of power hidden in the dragon's body, the existence of the Dragon Slayer Lacrima."】

【"Create a space similar to a Dragon Slayer Lacrima, or rather, a space for the Dragon Seed to grow. In this way, no matter how the dragon power develops, it will not affect the essence of being human."】

【"In other words, when you need to use it, open that space, just like a dragon mobilizing the power within the Dragon Slayer Lacrima."】

【"I think this can achieve a near-perfect evolutionary direction."】

【"Of course, all of this is a conjecture, and more research and overcoming more difficulties are needed to realize it."】

【Black Natsu talked eloquently.】

【And at this moment, Irene on the other side was already stunned on the spot!】

【Yes, Dragon Slayer Magic is essentially magic that converts humans into dragons, but humans are not dragons and don't have things like Dragon Slayer Lacrima to supply the growth of dragon power.】

【It is precisely because of this that people who often use dragon power will gradually turn into dragons, and their personalities will be eroded.】

【Simply put, it's a pollution source that can release power. A completely harmless method is to isolate it with something, and only open it when needed. This will undoubtedly minimize the side effects.】

【But how have they, the Dragon Slayers, been using it all along?】

【That is purely physical contact with the pollutant. It would be a ghost if they weren't infected.】

【After Black Natsu's reminder, countless ideas suddenly popped into Irene's mind.】

【In her excitement, Irene even hugged Black Natsu's head and gave him a fierce kiss on his forehead.】

【Then, holding the confused Black Natsu, she said in surprise!】

【"Listen, Natsu, you are truly a genius, absolutely the most terrifying genius I have ever seen!!!"】
