The very moment Leon accepted the terms, some magic words appearing in his right arm. Although they weren't words of Earth, he could understand their meaning since the contract was bound with his soul, just like it was with Tyrselle. The first topic of the contract was that Leon and Tyrselle would work together to reach a future which they could feel satisfied with. It was a bit vague for his tastes, but at the very least, it granted him the chance to reach a middle point between his goals and Tyrselle's.

The second topic was what Leon demanded from her. Tyrselle couldn't lie to him, and neither could Leon to her. The last topic was about how long the contract would last… it would last until Amanda, and his parents survived. Unfortunately, Leon couldn't put more persons there because, according to Tyrselle, even magic contracts had limits.

"Both parts have assigned the contract," Tyrselle said. "Now, we can work on helping things on your end."

"How can we do that?" the fourth Leon asked.

"We have to make you stronger," Tyrselle replied. "I can't interfere with the past more than I'm already doing. So, you have to do what you want with your own hands."

"That sounds fair…" Leon nodded. "In any case, what is your goal? You already know what I want, so it is only fair that I need to know what is your end goal."

Although he was a bit naïve, the fourth Leon wasn't stupid. Tyrselle couldn't lie, and it was better to learn what she wanted from the very beginning. Although Leon felt like he was putting too much trust into something created by a stranger, it was the perfect time to test if he hadn't been fooled or if that contract was really working on both of them.

"I want to… revive someone," Tyrselle hesitated, and that made Leon frown. "However, there are some people who intend to get in my way, so I need to deal with them.

"Revive someone… shouldn't that be easy given that you can talk to me when you are in the future?" The fourth Leon asked.

"No,… even my power has certain limits," Tyrselle replied. "Also, even though I also can make time move backward, it won't help me achieve my goal. To really obtain enough power to reach my goal, I need to deal with some… annoying individuals. With your help, I'm sure I will be able to get rid of at least one of them."

Still, after thinking for a while, Leon nodded that reviving someone was probably harder than control time. Why? Because the body of that someone probably doesn't exist anymore, and the soul existed in an unknown plane. Reviving someone was truly the hardest thing one could possibly do. By the look of things, one couldn't keep their memories once they control time to a distant point in the past. Or if there was a way to do that, Tyrselle didn't know, but Ilyana and Serena knew. Or perhaps just like Tyrselle suddenly recovered her memories, Ilyana and Serena also recovered them at some point. It truly was something complicated…

The fourth Leon doubted that one day he would become powerful enough to help someone who could communicate with the people in the past, but at that point in time, he didn't have the leisure to worry about that. Without thinking too much about it, he began his training and did everything Tyrselle told him, and on the first day, he learned how to manipulate earth, fire, water, and wind.

Tyrselle didn't forbid him from doing anything, so Leon taught everyone how to learn those skills. Of course, it wasn't like suddenly everyone became powerful enough to defeat monsters alone, but which tried to attack them, got decimated by dozens of elemental bullets from the next day onward since Tyrselle quickly taught him how to learn spells as well.

"Oh, man…" Leon sighed. "This is like… really bad."

Although the circumstances changed him, Leon always valued his friends and allies more than anything. Upon realizing that such knowledge prevented him and his allies from dying, the fourth Leon began to trust on Tyrselle more and more. Slowly, but surely, he was falling into the trap she was preparing for him.

Given that Ilyana wasn't or didn't try to intervene, Leon concluded that his hypothesis was probably correct. By using the spell to reset the time of everything, she and Serena had lost their memories and would only recover in the future.

Regardless, the fourth Leon spread the knowledge of how to use magic and learn spells like wildfire. Instead of worrying if that was a weapon that could be used against him later, he just wanted to help as many humans as possible. Thanks to that, many people began to follow him…
