"I guess I need to practice and make it more useful," Leon said.

"Practice what?" Hammath frowned.

Hammath couldn't help but feel confused. After all, Leon stayed quiet for one hour, and when he finally said something, his words didn't make any sense. Regardless, even though it was a pain keep using such a boring skill, Leon used it and spent his mana without remorse to level up Appraisal. Still, only after one hour and drinking several mana potions, Leon felt satisfied with the progress of the skill.

It looked like the more information the target has, the higher level Appraisal would have to be to show that information. Leon could approach and use the skill on the boss, but once he does that, the battle would inevitably start. Most humans or living beings couldn't feel Leon's Mana Dominions, but he was pretty sure a robot would feel it if he gets too close.

"I guess the safest way to start the fight is to charge the railgun and use it to cause as much damage as possible… but that would be way too convenient, and my goal isn't to defeat the boss… I need to get stronger."

In the end, Leon had no reason to let Hammath and Ava fight alongside him. He could give them a hand, but he couldn't let them get on the way of his goal, and one of the easiest ways to obtain free status points was using his skills on bosses.

"Sorry, but you guys will have just to watch me fight," Leon declared. "But if you two help me from the sidelines, I can give you another magic item for free."

"… What do we have to do?" Ava frowned.

"Just throw mana potions at me," Leon answered. "That will suffice."

Leon created a cart and then drop the contents of hundreds of mana potions inside of it. After that, he created two steel buckets… Hammath and Ava frowned when they noticed that Leon wasn't joking.

"Wait, we can help more than that!" Hammath protested.

"Yeah, I know." Leon looked away. "But I don't need your help. If you want to get stronger, I can give you a hand, but the boss is mine alone."

Fighting against bosses was the quicked way to level up skills, so Leon was a bit unreasonable trying to monopolize that advantage. But he couldn't care less about such a thing. He couldn't afford to waste time worrying about that kind of thing. He had and intended to use any means necessary to return to Earth as soon as possible.

"Fine… but how do you plan to help us?" Hammath asked.

"I can create the weapons you guys want to practice, or I can use magic to level up your resistances," Leon said. "It is your choice. Still, if you choose the second option, it will be painful. I can heal your wounds, but it won't be something pleasant for you guys. Besides, I will only do so until we reach the next dungeon."

It wasn't a bad deal, so Hammath and Ava readily accepted the offer. Although Leon assured them that they wouldn't die, they chose the weapons… but first, they had to defeat the boss.

"Don't get away from me, okay?" Leon asked. "Just stay close and use the mana potions on me."

"How are we going to proceed?" Ava asked.

"We will just face the boss normally," Leon answered. "You will see…"

It was common knowledge that facing a boss without causing massive amounts of damage in a preemptive strike was suicide. So, Hammath and Ava couldn't help but regret that they chose to follow a madman. Still, their opinions changed when they entered the final part of the dungeon, and the boss attacked Leon. Hammath and Ava imagined that Leon would be exploded in pieces, and then they would be the next to die, but nothing happened. Although they heard the sound of the boss firing something, they didn't see the object, but they heard the sound of something blocking the projectile.

"I guess it doesn't have health and stamina because it is a robot… but to think I would finally find the invisible attack I wanted to learn here…"

Although Leon was looking at that status screen, he didn't waste too much time thinking about it. He started to fire Thunder Bullets to stop the damn thing from shooting the invisible Mana Bullets. Although Leon's mana was decreasing at the same time the boss was spending mana to attack, he didn't want to fight for hours.

Thunder Bullet started to level up like crazy, and little by little, its effects over the robot were becoming stronger. Still, the machine barely stopped for half a second after getting hit by one of those.

"The power and level of Thunder Bullet were too low to use it against a boss… maybe this will get messy."

Thunder Bullet didn't cause damage, so Leon had to use his staff, but considering that he only made one, he wondered if that was enough. Still, little by little, his thick staff was damaging the boss. At some point, the boss stopped attacking and used its mana to repair itself.

"Good for me… it can't do two things at the same time."

That being said, the robot could barely repair itself since Thunder Bullets were continually interrupting the process… the thing was just wasting its mana. Meanwhile, Hammath and Ava were constantly making Leon's mana recover. Still, things changed when Leon clearly saw mana becoming visible in the dark hole that was located in the center of the boss. Even his Thunder Bullets couldn't stop it. The machine finally noticed that it couldn't defeat Leon without using its trump card.

"Here it comes…" Leon murmured.
