Even though Leon's power had returned, and he could use Supernova if he wishes so, Tyrselle was confident that she could resist the power of such an attack. Their skill and power reached a point where numbers wouldn't be enough to determine the winner of the confrontation, and that was why she was being careful. She couldn't afford to lose again… she had been struggling for far too long as well… she couldn't afford to waste any more time.
However, her hesitation disappeared when Leon obtained full control over the mana of the one-hundredth planet. Why her hesitation disappeared? It was because Leon's mana pool became half of the size of hers. Tyrselle bit his lips and then started to bleed in annoyance. That happened many times before… whenever she was confident of her victory, Leon would do something unexpected and then turn the tide of the battle just like that. Besides, using Mana Link was something that he never did before, so Tyrselle had no countermeasures against it.
"As usual, you are pretty quick at thinking of crazy ways to increase your power," Ilyana said while she was cleaning the droll near her mouth. "I think this is pretty unfair considering that had to create trillions of monsters over centuries to have this much mana, but I won't complain. Because with this, we will finally reach the seventh stage of the assimilation."
Tyrselle knew that Ilyana was right. If one could obtain full control over all planets in the universe that have mana, it was clear that that person would reach the seventh stage. If that weren't enough, then the seventh stage wouldn't exist. However, Tyrselle doubted that was the case. The seventh stage does exist, and she would reach and then obtain unlimited power.
Copying what Leon did would be easy, but for the time being, Tyrselle would have to defeat Leon and Ilyana because they wouldn't let her do the same. Tyrselle couldn't just go all out either because she couldn't afford to make the mana of several worlds disperse in the universe after destroying them. Although she knew that planets would become a lot more resilient thanks to mana, obviously, the destruction caused by a Supernova would decimate them.
Tyrselle breathed deeply to calm her nerves. The stakes were much higher this time. This would be her last chance to revive her little brother. If Leon and Ilyana reach the seventh stage, then they wouldn't reset the time again, and even if they do, they would have enough power to erase her existence from time and space… it was a dangerous spell that Tyrselle barely had used before. Still, she didn't hesitate in pointing her right hand toward Leon.
Suddenly, Leon felt a shiver like no other. As if some distortion was messing with the system, Leon saw his health, mana, and stamina bar trembling and slowly getting transparent. Leon's vision darkened… even though all his defensive spells were active. They didn't do a thing against that… against Death.
Leon's body vanished. There was no sign of blood or even of the damage he suffered because, just like he could use conceptual attacks to skill several steps when attacking, Tyrselle could do the same on a greater scale. She could skip the attacks when her target suffers the damage and just jump to the point where her foe just dies. However, space where Leon had been, distorted and his body returned to normal.
"Tch…" Tyrselle clicked her tongue when she saw Ilyana pointing her arms toward Leon and when she felt an invisible presence doing the same thing.
"To think she would develop such spell… she won't go down easily, Leon," Ilyana said. "Let's go all out."
"It looks like I just died again…" Leon frowned. "Well, it also looks like you can revert the effects of death as long as you are close and act fast… I should have expected no less from two masters of the time manipulation."
Regardless, after seeing how Tyrselle made a technique, he developed to reach the ultimate level. Leon recognized once more the fact that he couldn't be careless. Although he defeated her many times, she also defeated him. Leon wanted to make his kids recover their memories, but it looked like he will have to wait for a while before that happens.
"Master Tyrselle…" Sylas hesitated. "What can I do to help you?"
"… You have done enough," Tyrselle replied after a brief moment of silence. "Return to Earth and make our forces retreat. I will deal with those two alone."
"But…" Sylas insisted.
"You don't want to kill your fellow humans, right?" Tyrselle asked. "The ones you need to kill can't be killed because they are under his protection. So, any attempt in doing that would be a waste of time. Besides, I'm not sure if I can win this fight. If I fail, I don't want to die knowing that you and all the others will follow me."
Leon frowned when he heard that. Tyrselle's behavior was a bit different than he had expected, given that she caused the deaths of billions of humans and many other beings on other planets. Perhaps she changed her ways a little bit, knowing that she couldn't face Leon and Ilyana alone, even though she still wanted to kill anyone who may get in her way.
"… I will give you one last chance, Tyrselle." Leon glared at her. "You caused a lot of destruction and caused the death of too many… but we still can repair everything. Stand aside, and perhaps I will be able to…"
Tyrselle opened her arms, and then the entire world began to tremble… no… the entire galaxy began to tremble. That was Tyrselle's answer, and Leon sighed when she forcefully teleported Sylas away.
