After cleaning himself of all the blood, he returns to the corpse in his room. He then activates his all seeing eye and looks at his anatomy. He was quite surprised to see how the body reacted. It was the same as humans, however due to mana, it had been strengthened. He then put a bit of mana inside the body, and saw it go through the veins in his body. This however wasn't the strangest thing he had seen, as his heart had what he assumed to be runes carved into it. It looked extremely weird, but he had guessed why it was there. It was something like a mana booster, or a mana circle, as he would call it. Looking at the state of his heart it was safe to say it was self destructive way to advance your talent and mana capacity. It basically forced your body to take in more mana than it could handle. Using this method, it was a stretch to live 100 after using the technique. It seemed like this was a method only humans would use, because even if mana made you live an extra hundred years, you would still die around the same time with a magic circle. As for the fact he wasn't alive, he couldn't see how mana reacted to each organ and what controlled mana, which was a shame, but he could just watch his students use mana and deduce from their. As for his stats, he had a better idea what they all did after watching the mana go through the body and watching how his body changed when he put in his stat points.
Strength would increase the amount of force he could release from a standstill. Other things could be added but it would basically enhance his base strength using mana, it wasn't really that complicated, but it did however, include the mana he used subconsciously would increase, and the amount of maximum mana he could send to increase power would increase. Intelligence was affecting his overall control of elements, making it need less mana and more precise, while also increasing his mana capacity. Agility was pretty simple, it allowed his body to move at faster speeds, while strength used mana manipulation one way to increase punching force, this was just pure muscles, nothing more nothing less. It made his body stronger by allowing more mana to circulate throughout his body. Stamina just increased his total energy reserves. There was no real fancy mana manipulation, it was just strengthening muscles and increasing his pain tolerance. From what he had gathered. This however was his base analyses and it could very well be wrong. He was going to observe how his body changed when he put more stats in, as 1 per stat didn't really give a great display of the changes.
After that he goes to train his students, he decides to actually get their names this time. He had 4 students currently, they were Liam, Elijah, Emma and Mia. Liam had an fire affinity, Elijah had water affinity, Emma had a wind affinity and Mia had a lighting affinity. He then decides to find his starting point as a teacher.
"Can any of you manipulate your elements yet?"
All of the kids just shake their head, so he then manipulates his mana a bit and put it inside their body, just to kickstart their reaction towards mana. As soon as the mana enters the body, it changes, Liam's became more ferocious, while Elijah's flowed smoothly, along with Mia's surprisingly. Emma's mana went trough the most changes, mana would normally flow like a liquids inside someone, but hers appeared to change into a gas, taking up all the space it could. This was quite the surprise, but he had a guess as to what this was. It seemed the makeup of a body innately affected how it reacted to mana, his could take pure mana in, and fire out the element he desired. Others body would innately change mana so they could use it better. He then decides to what chanting a spell actually did, so he did the one he heard ruby doing awhile back, at the rank up test.
After he chants, the mana moves to make a fireball, but he instantly dispels it, he had blocked the area around the fireball by making a portal round to distort their vision. He had come to a basic conclusion. Chanting was a crutch mages would use to help themselves focus and manipulate mana easier by helping them visualize and he assumed it would just make them think of the spell like "wow, he said some words, if I do that, I can shoot a massive 200 foot fire pillar!" it was just mental manipulation, but it worked, for no good reason, but it did. As for how they should get mana, they would have to actively practice gathering mana until they do it without thinking. It was going to be an experience teaching some 8 year olds, but what did he care, he was going to bored doing his duty anyways, this was at least something new.
After giving the kids more mana and helping them develop a mana sense, he sent them home, and he started preparing for the party, because he was expecting the worst.
