Billy never wondered how a tennis ball felt before, but he could tell how it was now. The human body didn't have the ability to bounce well, so it could only absorb the impacts of larger objects and try hard not to be smashed by them. That was what he was doing now…
Zenis wasn't giving Billy any chance to counterattack or dodge. He could only defend and be tossed away while fighting the Gundam armor. His glaive could only take so many hits of that, but Billy was managing to repair it before real damage could be seen on it.
After numerous of those strikes, Zenis got tired and then suddenly increased his speed and attacked Billy from above. Much to his surprise, Billy reacted to that… probably because he absorbed his mana and enhanced his own speed. Nevertheless, that didn't change things that much… Billy was still pushed downwards and almost smashed like a potato on the ground.
The power of that attack hadn't been like the previous one that destroyed half of some mountains. However, Zenis still frowned when he saw Billy getting up after a couple of seconds… his wounds were mostly healed, and that wasn't supposed to. Be possible…
"... I see… he can also take the mana from my armor since it is an active spell," Zenis realized.
Zenis would never notice that in the middle of the battle… the reason was simple, he had way too much mana to begin with, and he couldn't feel his mana decreasing. Aside from a few times, he never tested his powers fully since he got the dungeon core, so it was only obvious that he forgot what was the feeling of running out of stamina.
Nevertheless, that whole situation was preposterous… he was being surprised by someone weaker time and time again because he couldn't grasp the extension of his own powers, and he felt that he had to amass as much mana as possible to make sure that he will survive in the end.
"The mana around him is being sucked even faster than before…" Billy thought. "He finally realized something… I was expecting to gain some more time, but I guess it is impossible. He doesn't know his full power yet, and he might kill millions if he tries to test it… sinking this whole continent shouldn't be hard with that much mana."
Billy could try to use his Personal Domain if Zenis tried something stupid, but even that ability had limits. He might be able to take an attack that was supposed to kill him, but an all-out attack meant to test the powers of a demi-god was probably beyond him right now. After all, if he takes a direct hit that has enough energy to destroy his body three times over, he still will die if he absorbs half of the energy.
Billy realized that he had to push the enemy against the wall, and he had to use the mana he obtained while doing that to keep Zenis busy. He had another idea in mind, but it would take some time for everything to be put in place.
After increasing his speed, Billy charged toward the enemy. All of a sudden, he decreased his weight with gravity magic, and then his speed nearly doubled thanks to that. Zenis swung his massive sword to split him in half and keep his distance. At best, Billy's range with his domain should be two meters, even with all his talent with magic. That skill was something that needed a lot of time to be improved, after all.
Billy's glaive took the attack directly, and his charge came to a stop. Still, with brute strength alone, Billy kept moving forward, and Zenis was unable to push him away while he felt the mana on his sword being absorbed. While clicking his tongue, he transformed his left arm also into a sword and tried to cut Billy's head. In the end, Billy stopped the attack with his right hand… his armor helped with that, but it suffered some damage, and he was pushed backward.
"All of these people are going to die anyway, might as well give them a merciful ending," Zenis said. "They won't be used by someone else as a tool to protect this world."
Billy didn't like to hear those words, and it was clear that the enemy had made up his mind to destroy everything around him in order to kill Billy. While clenching his teeth, he waited for the perfect moment to do his very best…
He waited until Zenis created a dark sphere that was firing dark lightning bolts around. Billy recognized that… it had the same logic as an absolute ice bullet. A combination of the propagation effect that gravity had and the power of damage control, but a lot more condensed. It was probably the upgraded version of the skill. In any case, that will definitely wipe him out down to a molecular level, and if it reaches the continent…
Billy charged toward Zenis, but the enemy predicted that much and then fired the dark sphere of energy toward him. At the last moment, Billy used all the mana he had accumulated on his spear and increased its power by leaps and bounds. Still, that hadn't been enough to stop or destroy the projectile. Instead of that, Billy began to be pushed backward…
To make things worse, Zenis began to fire other spheres like that and made the original larger with each passing second. Billy Personal Domain was absorbing some mana from the sphere, but not enough to counter all the extra that Zenis was putting in…
At the last moment, Billy had an idea… he copied Zenis once and he decided to use another of his techniques against him. Billy decreased the area of effect of his Personal Domain and then used it on his glaive. He used his best skill when the weapon began to pierce the dark sphere.
"GUNGNIR!" Billy shouted.
