The man's first reaction was to mistake Yakuchi Kei's Sharingan for a "Kakuugan (Ghoul Eye)", so he was momentarily stunned.
Ghouls can generally distinguish the scent of their own kind.
The young man clearly had the scent of a normal human, so how could he have a "Kakuugan (Ghoul Eye)?"
However, there is a situation where a Ghoul lives with many humans every day, and their scent gets mixed with human scent, making it difficult to distinguish.
He felt it was very likely that the other party was in this situation...
The man immediately "slammed on the brakes," seemingly no longer intending to attack Yakuchi Kei, and instead cursed, "Damn it, what bad luck! I thought I ran into 'food' that delivered itself, but it's one of us!"
He looked disgusted, because the flesh of Ghouls is different from the flesh of humans.
Ghouls have special taste buds; not only do they feel nauseous when eating normal food, but the flesh of their own kind is also very unpalatable. In contrast, human flesh is delicious to them.
Moreover, preying on humans can make them stronger, replenishing and even increasing the necessary "rc cells" in their bodies.
Although cannibalism among their own kind, also known as "co-eating," can also absorb "rc cells," the taste is much worse than human flesh, and there are not many Ghouls willing to madly pursue strength through "co-eating."
So this guy felt very unlucky after mistaking Yakuchi Kei for one of his own kind.
"Get lost, quickly! This is my 'Eating Ground.' If you dare to approach here by even half a step again, I'll tear you apart next time!"
The man spoke to Yakuchi Kei with an extremely malicious tone.
"Eating Ground," as the name suggests, is a place where Ghouls prey on humans. Many Ghouls delineate their own exclusive "Eating Ground." Stronger Ghouls often vie for larger and better located "Eating Ground," and then this place becomes private territory.
If one intrudes into another Ghoul's private territory without permission, it can easily trigger a brutal struggle.
The premise is that the other party is also a Ghoul. However, Yakuchi Kei is not a Ghoul, so the so-called "Eating Ground" rules are irrelevant to him.
He had been provoked to this extent; if he could still endure it, wouldn't he become a "Ninja Turtle"?
Yakuchi Kei did not respond with a single word. Instead, he used the D-Rank Ninjutsu "Instantaneous Body Technique" by expending the Chakra in his body.
That's right, he has Chakra in his body; otherwise, he wouldn't be able to use Ninjutsu.
The Chakra provided by Lv1 Hashirama cells, and also a portion of Uchiha Madara's Chakra, both streams of Chakra have already merged into one, so there's no need to distinguish them.
Yakuchi Kei instantly appeared behind the Ghoul using the "Instantaneous Body Technique." If the opponent hadn't almost reached him, the D-Rank "Instantaneous Body Technique" wouldn't allow for much instantaneous movement.
There are many types of Instantaneous Body Technique, and the D-Rank one is naturally the lowest and most basic.
Instantaneous movement is no longer a question of how fast it is, but rather that it makes it impossible for ordinary people to react, and that Ghoul also couldn't react in time.
"Great Fireball Technique!"
Yakuchi Kei silently recited in his mind, releasing the C-Rank Fire Release Ninjutsu "Great Fireball Technique."
As Chakra condensed in his throat, a fireball was exhaled from his mouth, rapidly growing from a small ball of fire into a massive one. The high-temperature flames engulfed the Ghoul in front of him.
Even though he had never learned it, he successfully released it on his first try, as if he was already very proficient with this Ninjutsu.
Although the "Great Fireball Technique" is quite awkward in Naruto, being a very popular Fire Release Ninjutsu that has almost never had a lethal effect—either being dodged, absorbed, or blocked in various fancy ways—to be fair, its power is still very strong.
When the Ghoul felt something was wrong and turned his head, he saw a huge fireball coming at him. His eyes widened in terror...
"Gah ah ah—!!"
The Ghoul, being scorched by the high temperature, immediately let out a scream.
A Ghoul's physical defense is far stronger than that of a normal human; ordinary weapons like kitchen knives are very difficult to injure a Ghoul. But even so, it was difficult to withstand the terrifying high temperature of the "Great Fireball Technique."
However, there was a problem: a Ghoul's regenerative ability is also very strong, making it difficult to kill them with a single blow. As a result, Yakuchi Kei's attack failed to kill this Ghoul.
Seeing this, Yakuchi Kei decisively picked up a crowbar from the ground nearby, also known as the "Holy Sword of Physics."
A Ghoul's physical defense is indeed very difficult to injure with ordinary weapons, and a crowbar is certainly within the scope of "ordinary weapons," but great force can work wonders.
He possessed Uchiha Madara's taijutsu, though it was only a superficial understanding, it should be enough for now.
At this moment, Yakuchi Kei exerted force fiercely, relying entirely on brute strength to strike the Ghoul's Bikaku Kagune.
The Kagune, already scorched by the high temperature, was naturally not as hard as usual. His full-force strike broke the Kagune.
The Ghoul was in immense pain from the scorching. No matter how strong his physical defense and regenerative abilities were, it didn't prevent him from feeling pain, to the extent that he completely failed to realize the seriousness of the problem.
Immediately after, Yakuchi Kei followed up with another "strike," completely breaking off that Kagune.
He then used that Kagune in place of the "Holy Sword of Physics" in his hand.
In this world, there is a weapon specifically used to deal with Ghouls, called a "Quinque." It is actually made from a Ghoul's Kakuho and Kagune. The key lies in the Kagune's extremely strong lethality and hardness.
Therefore, this thing can be used as a temporary weapon, and its power will only be stronger than the "Holy Sword of Physics."
To be precise, the power is not even on the same dimension. The Ghoul lost this "Kagune" that served both offense and defense, and its body was instantly pierced by Yakuchi Kei using the Kagune in a backhand strike, as easily as cutting through butter.
Inside the Ghoul's body, at the base of the Kagune, there is an organ called a "Kakuho," which is the most important organ in a Ghoul. It was directly destroyed by Yakuchi Kei, inflicting a fatal wound on the Ghoul.
The screams gradually died down. Lying on the ground, barely alive, it was only a matter of time before it completely died.
Perhaps in its last moments of life, it felt immense regret for provoking someone it shouldn't have.
[Ding! Host has defeated a "B-Rank Ghoul" and received a reward: 5 Fusion Points!]
Upon hearing this system prompt, Yakuchi Kei immediately realized that fighting Ghouls could also earn Fusion Points.
This was, of course, very good news; he now had more ways to become stronger.
At this moment, Yakuchi Kei opened the system panel with his mind and took a look, finding that the [Fusion Points] section had accumulated 87 points. This meant he only needed 13 more points for his fusion progress to advance to Lv2.
At that time, he expected all aspects of his abilities to improve comprehensively, and his Sharingan would certainly be more than just one tomoe...
