*Baam!* *Baam!* *Baam!*
A gravel fell from the air and hit the ground, causing a loud sound that echoed through the room.
Raikou and Karna that were separated by 100 meters distance, looking at each other, and the magic power that emitted from their bodies were undulating, showing how much magic power that they were about to use in the next clash.
Air currents surged around the two of them.
The flames and lightning covered their bodies like a coat, seeing Raikou's body that constantly flashed with domineering and powerful lightning, Karna finally spoke.
"It seems that you have gotten rid of the existence of Oni inside your body."
In the last battle, the Oni inside Raikou was awakened and it was also the reason why she had lost her mind at that time.
"The Oni inside your body was originally yourself when you were living as a Ushi-Gozen."
Karna possessed a skill that made him capable of seeing through anyone.
"I wonder what kind of catalyst your master used so it will trigger the Oni inside you to awaken."
After all, Haru had eaten "Horo Horo no Mi" and gave him the ability to manipulate a ghost or become the ghost itself.
When someone ate a Devil Fruit, the lineage factor or the DNA inside their bodies changed so it gave them supernatural power.
With the power of "Horo Horo no Mi", and as the descendant of Ootsuki Ashura who happened to be the brother of Ootsuki Indra, the existence of Oni inside Raikou became even stronger than before, especially when Haru used his own blood as a catalyst to summon Raikou.
However, with the power of anaconda, pleasure magic, light magic, and love, the Oni inside Raikou was suppressed and his "Mad Enhancement" level was also lowered, showing how cheating Haru's existence was.
His harem protagonist aura also helped Raikou too.
However, even if Karna was capable of seeing through a lot of things, there was no way that he could see everything inside Haru.
It was also because of that, the current Raikou wasn't a Ushi-Gozen, but rather the strongest Mystery Slayer, that commanded a military army and protected Kyoto.
"If it's you now, then I don't have to be merciful."
With such words, Karna suddenly raised the sharp spear in his hand and the flames began to burn on his body.
"Come one..."
Under Karna's whisper, the flames began to burn again with very high temperature and formed into a whirlpool, like a tornado of flames, and gradually gathered around his sharp spear.
Under the scorching heat, the space around Karna began to twist, and the ground under his feet became dry and cracked turned into a wasteland.
At that moment, Karna was like a little sun that was burning on the ground.
The high temperature brought by the flame already made Raikou, who was a hundred meters away from him, feel an unbearable hot wind rushing toward her, making her whole body start to sweat.
This situation caused Raikou's expression to become solemn.
Brahmastra Kundala is a Noble Phantasm obtained by Karna from Brahman Parashurama. The appearance of this Noble Phantasm can change, if Karna is an archer then it will turn into a bow and if Karna is a Lancer then it will turn into a spear.
Even if Karna changed into another type of servant, this Noble Phantasm would change into another projectile type of weapon.
If Karna decided to use this Noble Phantasm, Karna's attack would contain the strength of the servant that was equivalent to Rank A. If it was released with magic power, the power that it brought would increase to another level, therefore this Noble Phantasm was very dangerous.
It was also the reason why Karna, who had only a strength level of B Rank, was capable of competing with Raikou head to head.
However, the power of this Noble Phantasm could be improved even further.
When Karna released the True Name of this Noble Phantasm, the effect of the "flame" which was his attribute would be given to the Noble Phantasm, which would further expand the scope of effect of this Noble Phantasm and even increase its power even further.
At this point, Karna's Noble Phantasm would be powerful enough to match a nuclear weapon.
Now, Karna liberated the True Name of this Noble Phantasm.
"This is not an imitation of Arjuna...! Beware the sky, I think it is going to get worse.
"Brahmastra Kundala!"
The great charity hero of the Indian epic suddenly raised his foot and took a step forward with enough power to crush the ground.
Immediately, the sharp spear wrapped in crazy flames fiercely released from the spear.
*BOOOOM!*
The brilliance of the flame was comparable to the sun itself.
The spear was moving toward the sky, and it turned into a meteor of flames, mixed with an avalanche-like aura, intending to completely burn out this space and explode in the direction of Raikou.
The terrifyingly high temperature suddenly hit Raikou like a stormy wave.
Raiko smiled confidently as she watched the blow that was shot by Karna toward her like a meteor.
"In that case...."
The magic power surged on Raikou's body.
"Then I will show you my power, the hero of the Indian epic!
"Use your eyes that can see through of everything, look at my pride and dignity!
"This is what I have!"
Raikou declared loudly!
"Come to me, my loyal subjects, my limbs, my arms, and armor! The Four Heavenly Kings themselves are as before you. Begin…!"
It was an order that Raikou used for her subordinates in the past.
"Now is the time to use your soul in my thunder and sweep the gods and demons!"
Following Raikou's loud declaration, Karna was startled since he had seen something and the pair of his eyes suddenly widened.
"Could it be...!?"
Karna raised his head abruptly and looked up.
Beyond the Hanging Garden of Babylon, to be more precise 3,000 meters above it.
Even if there was a ceiling that was blocking him, Karna could see it clearly.
Above the sky, a burst of black clouds came like a tsunami and finally gathered like a whirlpool in the sky above the Hanging Garden of Babylon.
*Rumble!* *Rumble!*
Thunderstrike sounded!
In the next second, four falling thunder burst out, piercing through space and time, without any hindrance, and easily penetrated the building on the Hanging Garden of Babylon and came to Raikou's side.
*BOOOOOOOOM!*
The four falling claps of thunder suddenly landed around Raikou.
Inside each of the four claps of thunder, there was a figure.
Karna instantly understood what Raikou's Noble Phantasm was.
"This is my Ox-King Storm Call - The Inescapable Net of Heaven! "
