Unlimited Power - The Arcane Path

That was a very scary thought. Unfortunately, Leon didn't doubt Ilyana even for a second. Not a single species would have survived the assimilation without taking some drastic measures. Leon began to imagine the size of destruction a human could cause if their body were half made of mithril, and Leon could clearly see such a thing wiping out an entire city leaving only a big hole in the ground.

"I more or less can understand how dangerous such a thing is, but considering that, do you really think it is fine to let me do that job?" Leon asked.

"Yeah, you can handle it," Ilyana said. "Besides, I know that you quickly get bored with training. So, that will work as a good change of pace. If you fail to prevent their landing, you can defeat such soldiers by consuming the mithril on their bodies. Their bodies will explode after they lose some of it, but you can cancel the explosion by using Anti-Mana Field."

Leon nodded, he could prevent the worst-case scenario, but it still was very scary. He recalled that his Anti-Mana Field could prevent the use of magic, so most likely, the explosion wasn't a spell, it was just the after effect of some chain reaction caused by a small amount of mana. However, it was the kind of job Leon was waiting for... he really had become an adrenaline junkie.

"It won't be bad if they noticed that someone is living on the planet?" Leon asked.

"I want them to notice that, if someone is living there and that someone can stop their spaceship, then they will leave and look for another place," Ilyana answered. "After traveling through outer space, any intelligent species wouldn't take the chances of facing someone or a species capable of doing that."

Leon nodded again, but he still couldn't imagine himself doing something like preventing a spaceship that was transporting an entire alien civilization. Upon noticing that, Ilyana interrupted his thoughts.

"You can easily solve that problem if you use your zombie snake," Ilyana said. ��But, it would be better for your growth if you use your magic alone."

"Can that snake even follow my commands from so far away?" Leon frowned. "It will even arrive on time?"

"Yes, that monster can move much faster than you think," Ilyana answered. "If you give the order, it should arrive on that planet in one week. The spaceship will only arrive in two weeks. I'm saying this to you know in order to give you some time to prepare yourself."

The job was difficult, but Leon wouldn't have to kill anyone or exterminate an entire species just because Ilyana said so. The chances of him having to do that weren't low, but as long as Leon prepares himself accordingly... the worse can be avoided.

"Things would be much simpler if I give you a Soul Eater, but you won't accept it, right?" Ilyana asked.

"... Yes, but how can you produce such a weapon?" Leon frowned.

"You don't have the skills necessary, so it is useless to explain," Ilyana answered. "Well, I hope to hear good news the next time we see each other."

Ilyana used Teleport and Leon appeared in the middle of a forest. He didn't hear anything aside from the sound of the wind and some insects. There were no monsters nearby, so Leon relaxed a little bit.

"I guess to create a magic weapon using mana alone. I need a few more skills. Still... how does she know the exact time the spaceship will appear? I thought she could monitor several worlds, but it looks like her monitoring network is much larger than I expected."

"What is the plan?" Celsius asked. "Are you going to prepare a cannon and explode the spaceship?

"... You have a scary imagination," Leon frowned. "I don't want to become a species slayer. Even if they reached a point where they use their soldiers' remaining to cause the death of their enemies, I don't want to do anything to them unless they cause problems for Earth and me."

"There is always a chance that they might go Earth after deciding to leave this place alone..." Undine said, smirking.

"Even if that happens, Ilyana will probably warn me with some antecedence," Leon explained. "If that happens, I will deal with them the same way I deal with those who try to screw with me."

Although Undine was probably joking around, Leon decided to take things seriously. That was possible, after all. Regardless, it was time to begin his preparations. If Leon didn't want to make unnecessary enemies, then the only option he had was to use Gravity and Telekinesis to make the spaceship turn around and return to whatever direction it came from. However, Leon knew that with his current mana pool, that was impossible. Perhaps if he levels up both skill up to the level max, that will solve the problem, but that was unrealistic. In the end, Leon needed something like Soul Eater, but he would rather create something like that instead of relying on someone else's tool.

"Things could have been solved much faster if Ilyana had teleported me while carrying several containers filled with mana liquid... but I guess she wants to me solve this problem doing something else."

Soon, Leon understood that was just the beginning. There were animals there and plants, but Leon couldn't feel mana in them. So, Leon wouldn't be able to absorb their mana. After a few hours, Leon also confirmed that there were no monsters in that world, not even the ones that belonged to Ilyana.

"Some this is off..."

That planet had mana, but no monsters. Most likely, Ilyana killed every single monster in that world, or she hid them very well... then everything started to make sense.
