Demon Lord's Reincarnation

After assessing the level of his new subordinates Ren thought up ways to train them; but first he needed to train his strongest companions which were Lara and Hilda. That was going to be hard, seeing as he already taught Lara everything he knew about archery, which she was most suitable in. Even her ability to use Darkness magic was near his level. She even stopped using darkness magic, since the spells she could use consume a huge portion of her mana, making it an inefficient way to fight.

Hilda on the other hand, was a whole other problem. She was already used to her own style of fighting, and teaching her new ways might actually hinder her growth. All of Ren's' fighting styles were purely offensive, even the people in his visions were of the offensive type, but Hilda's style was more well rounded.

"Silika."

After calling her name, a woman wearing a black veil matching her black dress appeared before Ren. Hilda and Lara were already aware of Silika's presence, but Iselv and the others were amazed by the sudden appearance of Silika. Since it was like she appeared out of thin air.

"What do you wish for, my master."

"I want you to spar with these two." Ren pointed at Lara and Hilda.

"As you wish my master." Silika then summoned the deathscythe. Hilda and Lara were surprised on what was happening, and stood there dumbfounded.

"You two, this is your training. Basically you just need to fight with Silika. The only way to clear this training, is if you are able to hit Silika once. Can you guys do it?"

Hilda didn't answer and simply readied her sword and shield, Lara did the same and held five arrows on her hand. Ren smiled seeing the reactions of the two.

"No need to go easy on them. Just make sure not to kill them."

"As you wish my master."

...

After instructing Silika what to do, Ren headed towards the two beginner level mages. The two girls stiffened as they stood face to face with Ren. Usually they wouldn't fear any man no matter how powerful, because they could use their bodies to control them, but Ren wasn't someone they could use their charms on. Even their mistress Kithra whose beauty was known far and wide, but even she couldn't get a glance from this man.

"The two of you will be training to first increase your mana capacity basically making your mana pool grow larger. Usually one must wait for the mana pool inside oneself to gradually grow. Yet there is a way to forcefully strengthen your mana pool, at the beginning stages before you reach the high-end level. You just need to exhaust your mana reserves, until you faint. After that once you wake up I want you to do it again. You will repeat this until I say otherwise, do you two understand?"

"Yes!" The two had no other choice but to say this. The look Ren gave them, told them that if they won't follow they weren't needed. They didn't know what kind of thing this man will do to those he doesn't need.

Hearing there enthusiastic answer Ren nodded in response and left the two girls and headed towards Iselv and Kithra.

"You two I'm unsure on how to train you. I guess for Iselv I could teach you the basics of my swordsmanship, but with your incredible strength, I guess using blunt weapons like a warhammer is a better option. For now how about trying to cut down those trees over there."

Ren pointed at the nearby forest.

"Huh? Is there any point in doing that, I could do that easily." Iselv without any stance simply lifted his axe using both his hands and chopped at the tree. A huge chunk of it was chopped off, after a two more swings the tree fell.

"See," Iselv pointed at the fallen tree.

"No I don't want you to cut down the tree that way. I want you to cut it down using one hand and in a single motion, here give me your axe, I'll show you."

Iselv handed Ren his axe. When Ren held the axe he adjusted his strength to match that of Iselv's strength. He then lifted the axe with one hand, he then took a stance. His feet were slightly apart, left foot a bit forward. He lowered his body a bit and then using his one arm he swung the axe along with his waist which twisted as he swung the axe.

With one swift motion, Ren was able to cut down a tree in slice.

"That's how I want you to cut down a tree. Don't tell me it's impossible, since I did it with the exact same strength you have."

Ren then handed the axe back. Iselv who now held his axe gritted his teeth as he tried to copy Ren's stance and chopped on the tree. Seeing Iselv was now occupied in trying to chop a tree in a single move, Ren shifted his attention on Kithra.

In truth he really didn't know how to best train this woman. So he just explained to Kithra how to do his meditation technique. Upon hearing Ren's explanation, Kithra immediately tried it.

...

Everyone was now doing something there was only one person left, and it was the man called Hanz. The youth saw Ren approaching him at this moment he had a multitude of emotions regarding Ren, but the one emotion that struck him the most was fear.

"You're already an intermediate level mage and your mana pool is decent enough, but your body is too weak. There are two options you could take right now. I'll give you the option to choose which training style you prefer to use. The first option is the traditional route, which is basic training to strengthen your foundation, doing this will make you stronger, but the results won't be apparent in the beginning, and you'll only see changes after a few months. The second option is one of extreme pain and suffering. Yet picking this option, your body will get stronger faster, in a few days you will see great improvements. So which option will you choose?"

Hanz looked at the smirking Ren, who seem to be already aware which option he would choose.
