Still, even though Leon said that he wasn't in a hurry, Yuki appeared five minutes later alongside Ren. Leon sighed, or Ren was the most loyal guard he had ever seen, or he was the creepiest simp of the entire cosmos.

"Hello, did something happen?" Yuki asked.

"No, I just came to buy a few things, and I think things will faster if I negotiate with you directly," Leon said.

"Thank goodness..." Yuki sighed in relief. "You always appear so suddenly, and when something troublesome is about to happen, so I thought... Anyway, what do you want to buy?"

"The most potent computer you have that can work using rechargeable batteries," Leon said. "I also want all the knowledge you have on technology, be military, robotics, and of other more general areas."

"... What?" Ren asked, surprised.

"Why do you want something like that?" Yuki narrowed her eyes.

"I want a hobby and produce something that will help me in the long run," Leon explained. "Since I don't know much about technology, I will need even the most basic materials that will teach me about the subject."

"I don't think you alone can produce anything really useful," Yuki said. "That is even truer considering that you are a beginner in the subject."

"It doesn't matter," Leon said. "If I fail, then it will serve as a lesson. Don't worry about it, I won't give the information to anyone, and I will pay for it."

Yuki and Ren looked at each other, showing some doubts in their eyes, it made sense since Leon also wanted to learn about their military technology, but it looked like they were more worried because that was a massive waste of time for both parts. Leon sighed and created some earth above his right hand. After that, he used Transmute and create a pair of sunglasses.

"Do you still think this is a waste of time?" Leon asked.

"How did you... no, it doesn't matter," Yuki shook her head. "It will take a while to organize everything."

"All right, I'm not in a hurry," Leon said. "How many days you need do you need?"

"To digitalize everything, organize the parts and install all systems... perhaps three days will be enough," Yuki said.

"All right, I will return in three days," Leon said and then turned around to leave, but then stopped. "Do you guys need help with anything? I can lend a hand if you want."

"We don't have anything troubling us..." Yuki said. "But, you can help train our troops if you want."

"How?" Leon asked.

"Yes, Your Majesty," Ren bowed, and then Yuki left.

Although it was a bit weird for her soldiers to be trained around that time, Leon knew that Yuki herself had become a battle maniac. So, it wouldn't be weird that she demands from her soldier rigorous training day in and day out. Although it wouldn't be that efficient since Earth was on the fourth stage of assimilation, it wasn't so bad... Leon had to interact with other people now and then, after all.

The training grounds in question was located where a long time ago existed a soccer stadium. It looked like the building withstand the end of the world, and Yuki decided to reform the whole place and create a place for her soldiers to train to some extent. Most people on Earth became super-humans, so they couldn't go all out in such a place.

Even from afar, Leon could feel some vibrations on the floor coming from the center of the stadium. A few minutes later, Leon and Ren found the origin of the impacts. Some soldiers were punching each other or trading blows using their weapons without moving the spot they were in.

"All right, guys," Ren clapped his hands to get the soldiers' attention. "Change of plans, today we will practice our parrying skills and our resistances against a mage. This is Leon. He is going to help us with that."

Some soldiers recognized Leon while others looked at him as if he was a nuisance. Training against mages wasn't that fun for melee fighters. They couldn't attack, after all. And many felt like punching bags. Still, the number of soldiers was relatively high. It would be difficult to hit them fast enough without risking exploding their heads. Although Leon wasn't skilled enough to shoot with precision so many targets, he could easily solve that problem using his mithril helmet.

"... What is that?" Ren asked while he was observing Leon equipping the mithril helmet.

"A special helmet that will increase my accuracy," Leon answered. "Will you join them?"

"I will wait for Her Majesty," Ren said.

The soldiers readied their weapons, and Leon selected the targets and also the place where he was going to hit. It was weird how such equipment could improve his skills to that extent, but he wouldn't waste time questioning about it.

Without wasting time, Leon cast Ice Punch and multiplied their numbers using Multi-Conjuration. In the blink of an eye later, the magic projectiles hit the soldiers' weapons. Some of them endured the impact while others fell back after lacking the strength to endure the attack.
