### Chapter 24: Thunder God Mode
"?!!"
"Full strength?!"
"Does that mean Riku didn't use his full strength just now?!"
"How is that possible?!"
Hearing Gildarts' words, the few people were stunned. The strength Riku displayed just now was already heaven-defying, yet Gildarts said Riku hadn't used his full strength.
"As expected, I can't hide anything from Teacher."
Riku's words shocked the others. He really hadn't used his full strength?!
But the power Riku just used was already several times stronger than when he fought Mystogan!
If he had used this kind of power from the beginning, Mystogan wouldn't have been able to withstand it at all.
"Kid, hiding things from me? With the strength you had three months ago, after training desperately for three months, it's impossible for you to only have this level of strength."
Gildarts had witnessed how fast Riku's strength grew. This kid improved rapidly almost every day; he was the most monstrous genius Gildarts had ever seen.
The key was that this kid looked honest, but he wasn't idle at all. In the first month, he often created various moves. After three months, Gildarts didn't believe this kid would have stopped advancing.
"Come on! Don't think you can hurt me! You're a hundred years too early to defeat me!"
"Yes!"
Since Teacher Gildarts had spoken, he naturally had to bring out his full strength.
Crackle crackle!!
Dense lightning radiated from Riku's body. Riku's hair stood up, resembling Super Saiyan 2. Lightning particles gathered on Riku's legs and arms, and a ribbon formed of lightning wrapped around Riku's body, making him look like a god from mythology.
Thunder God Mode!
Riku's exclusive combat form that he had researched.
A move created by combining Enel's Thunder God form and the Fourth Raikage's Lightning Release Chakra Mode.
Everyone was very surprised to see Riku's transformation.
"...?!"
Just looking at Riku's transformation, they felt a terrifying oppressive force.
Gildarts' expression also became serious. After Riku transformed, he also felt a threatening aura.
"Teacher Gildarts, here I come."
"Come!"
BOOM————!!
The ground beneath Riku's feet exploded. In the next instant, Riku appeared in front of Gildarts, punching towards him.
Gildarts was shocked. This wasn't teleportation, but pure speed.
Gildarts hurriedly dodged.
Riku's fist hit the spot where Gildarts was.
BOOM—————!!
A terrifying explosion erupted suddenly, like a meteorite falling.
"Ughhhhh!!"
"Waaaaahhh!!"...
Natsu and the others watching from a distance were also blown away by the violent shockwave, landing far away before stopping.
After a while, the smoke from the explosion dissipated.
"What... what is that?!!"
Everyone looked towards the battlefield and saw a huge crater hundreds of meters in diameter where Gildarts originally stood. Riku was standing in the center of the crater.
"Did Riku cause such terrifying destruction with one punch?!"
"Monster————!!!"
Natsu and the others looked at Riku in the center of the crater with horror on their faces. Although they already knew Riku was a monster, he seemed to have become even more of a monster now.
Gildarts' eye also twitched, thinking: This kid, I told you to use full strength, and you really didn't hold back! At least I'm your teacher; aren't you afraid I couldn't catch it and get killed?
Riku stomped his foot and rushed rapidly towards Gildarts; the ground he passed over shattered with a boom.
Gildarts also rushed forward quickly.
Riku punched towards Gildarts.
Gildarts also threw a punch to meet him.
The two fists collided.
"BOOM—————!!!"
Their fists collided like Mars crashing into Earth. The shockwave generated by the powerful energy explosion spread rapidly outwards. The ground, trees, rocks—everything touched by the shockwave was reduced to ashes.
"Ughhhhh!!"...
Even from a distance, Natsu and the others felt a violent shock, their bodies unsteady.
After a while, the smoke cleared, and everyone saw the situation in the center of the battlefield. Both bodies retreated backwards. In this clash, it seemed they were evenly matched, with neither gaining the upper hand.
"What strong power!"
Gildarts felt his arm numb and painful. He had used his Magic just now to decompose part of the lightning particles on Riku's fist, but he couldn't decompose the energy shock erupted by the lightning.
Zzzzt!
Riku's figure disappeared instantly. The next moment, he appeared in mid-air behind Gildarts, raising his leg high to chop down at Gildarts.
Seeing this, Gildarts hurriedly dodged.
BOOM—————!!
Another terrifying explosive shockwave.
"Ugh!!"
Gildarts gathered Magic Power to defend, but his body was still blown away by the terrifying shockwave.
Soon Gildarts landed, pressing his palm on the ground and shouting loudly.
"Decompose!!"
The earth shattered, decomposing into hundreds of cubic blocks about a meter in diameter, scattering towards Riku's direction.
"El Thor (Judgment of God)!!"
Riku raised his palm, releasing a thick pillar of lightning, clearing almost all the large number of cubes in front of him in an instant.
Swish!
Gildarts' figure instantly appeared behind Riku, pressing his palm towards Riku's back.
"All Crush!!"
