Psychokinetic Impact!
Rumble!
Two invisible currents of air intertwined, and a massive mushroom cloud rose into the sky.
"As expected of King-san, to be able to block this move so easily." Mumen Rider sighed with emotion.
He had once used this move to insta-kill several Dragon-level Monsters.
'Damn, if I hadn't improved so much during my trip out, I might not have been able to handle him.' King was both surprised and delighted.
Saitama had already broken his limiter.
With King's help, Sweet Mask had integrated Union Power, and under the research of Psykos and Dr. Genus, he successfully fused the cells of several powerful monsters to achieve his current combat power.
Genos relied on the continuous improvements to his equipment by two mechanical geniuses, as well as the growth-type Battle Suit gifted to him by King. After the Great Robot War, his strength underwent a qualitative leap, and he also gained Union Power.
Looking at Mumen Rider, he was the Hero's Heart holder who had received the least from King. King hadn't even given him Union Power.
Before leaving, he had only asked Bang to help with training. Even so, Mumen Rider had managed to forge such formidable combat power through sheer willpower and perseverance.
"Actually, I still have one ultimate move. Please be careful." Mumen Rider's expression became serious.
'Another one? He is giving me quite a few surprises.'
King stood ready. The stronger Mumen Rider was, the happier he naturally became.
Energy accumulated frantically within Mumen Rider's body, quickly reaching a critical point.
"Finisher! Infinite Justice Combo!"
Boom, boom, boom!
Mumen Rider threw out countless punches. Every strike contained terrifying power, and the force was continuously intensifying.
Second Layer Liberation! Ten Thousand Punch Barrage!
Swish, swish, swish!
The attacks of both sides collided, and the violent impact made the entire barrier tremble incessantly.
Mumen Rider immediately fell into a disadvantage, but his Fighting Spirit did not diminish. Instead, it increased. Even though he was hit by several punches, he didn't care at all.
"Ora ora ora!"
Mumen Rider's punching speed grew faster and faster, his hands turning into afterimages.
'Is it similar to stacking Fighting Spirit? What terrifying comprehension.'
King was shocked by Mumen Rider's technique. If he didn't interrupt him, the upper limit of this move would continue to break through, just like how he used to accumulate Fighting Spirit.
But King possessed the abnormal Talent Fusion System, while Mumen Rider had relied entirely on his own hard work throughout his journey.
Multiple Gravity Punches!
Boom, boom, boom!
Countless punches roared out, but their power was dozens of times stronger than before, instantly annihilating Mumen Rider's attack.
'Is it still not enough? No, I cannot fall.'
Mumen Rider felt a terrifying aura sweeping toward him, and his gaze became incredibly firm.
"Unyielding Justice!!!"
Mumen Rider roared, and the Fighting Spirit all over his body increased several times over once again.
"Super Finisher!!! Fist of Justice!!!"
Rumble!
Mumen Rider seemed to break through a certain critical point, and a punch containing terrifying energy was unleashed.
This is?! Hero Power!!!
King was truly shocked this time. Although he also possessed Hero Power, after mastering Stellar Power, the boost from this power had begun to seem a bit insufficient.
But this surge of power that Mumen Rider was erupting with now was something he had only seen in one other human—Saitama.
Limit Break!
Hero Power!
Stellar Power!
Sixth Layer Liberation! Shattering Might!
King cast aside any playful thoughts and raised his power to its peak.
The two punches collided.
Super Dimensional Portal!
Hum!
King knew the barrier could no longer withstand a technique of this magnitude. He immediately summoned dozens of portals, transferring most of the attack into another dimension.
Rumble!
The energy within Mumen Rider's body was completely exhausted as the shockwave rushed toward him.
However, just as he was about to be turned into ash, his figure disappeared from the spot.
"King... King-san, I didn't embarrass you, did I..."
Mumen Rider forced his body to stay upright, looking at the man before him.
"Well done, you are truly a hero."
The corners of King's lips curled up slightly. He finally understood the importance of conviction.
It had been the right decision not to give Mumen Rider Union Power back then, whereas he himself had been filled with all sorts of different powers.
'So that's how it is. I now understand the significance of the Talent Fusion System's existence.'
After this battle, King had a sudden realization. He could also understand why Saitama's moves were so simple and singular, yet so powerfully destructive.
'No matter what power is mastered, can the greatest power only be exerted when everything finally returns to one? I understand.'
[Ding! Congratulations to the host for gaining enlightenment on the Hero's Heart. Full liberation authority has been activated.]
Hearing the system notification, King couldn't help but smile slightly.
This enlightenment on the Hero's Heart was completely different from before. Previously, he had only treated Hero's Heart as a tool to increase his strength, never as a conviction.
'Then from now on, the path I walk will be even more pure.'
Feeling the change in King's aura, Mumen Rider felt that the man in front of him had become even more inscrutable.
[Ding! Beginning fusion of talents. Progress: 1%...]
King opened the system interface in surprise and found that the skills he once possessed were gradually disappearing one by one.
However, his strength was increasing rather than decreasing. Waves of power were constantly gushing out. But this fusion process was slow, and he didn't know how long it would take.
'When this is completed, I might truly be able to challenge Saitama.'
King's state of mind was exceptionally peaceful at this moment. He wasn't ecstatic because of the increase in strength, everything felt as natural as water flowing into a channel.
"King-san?"
Mumen Rider stood up. In just this short amount of time, he had already recovered more than 50%. From this, it could be seen that his recovery ability was not at all inferior to King's.
"Hmm? What is it?" King snapped out of it at the call.
Waiting for the system to complete the fusion would still take some time, and he suddenly remembered that he seemed to have things to do.
"King-san, there is something I want to tell you."
Looking at Mumen Rider, who seemed to find it hard to speak, King couldn't help but feel a bit puzzled. "What is it? Just say it."
"Do you believe there are ghosts in this world?"
"Huh?"
King's face was full of question marks, not understanding why Mumen Rider would suddenly say something so nonsensical.
"Perhaps only you would believe me. I often hear strange voices."
"Are you sure?" King looked suspicious.
Mumen Rider's current strength could be considered among the peak ranks on Earth, he certainly wouldn't speak without reason.
"Yes. Every time a disaster occurs, I hear a voice ringing in my ear."
"What did that voice say?"
"It's you! It's you! It's you!"
