Guardian Of The End

"Ha… I need a bath now and a change of clothes as well." Jason muttered once he was done with his training.

His body was extremely sweaty and his clothes had been torn off in many places. Despite these, he was barely able to cut the metal a bit.

The trick was to maintain the stability of the thunder and make sure it remained stable at the tip, which was the area directly involved in cutting the piece of metal.

Unfortunately, the time was over and he would have to wait for the next day to arrive to continue.

'System, do you think I should tell my grandparents about Hecate's memories? We might be facing a war soon.' Jason questioned on his way back home.

[ There is no harm in telling her that. Maybe we will be able to learn more things about the demon king and Julian. ]

'Remind me to ask them after dinner.'

Once Jason had arrived at his home, he immediately went to his room and entered the showers. He stepped out after thirty minutes and changed into a new pair of clothes.

'I wonder what training I have to face with grandma…'

Jason still remembered the first time he had visited Risa's lab. It had ended up with him taking care of several Eelfishes.

[ Liar. You ended up killing so many babies. ]

'Hey, there was nothing I could do! I was still a newbie at dark magic control then.'

[ You are still don't have that advanced of a control. Though you are better than a lot of people, many mages far exceed you in dark and light magic control. ]

'Not for long though. I am not training just for the sake of training you know.'

While debating with the system, Jason made his way to the back of the manor. Risa had asked him to directly come to the lab.

'She definitely told me that I could see things without any worries now.'

[ She also said that you should use your vision ability with dark mana just to be safe. ] The system reminded.

Jason sighed before activating his mana vision. He could immediately see the mana particles in his surroundings.

He stared at the door for a few seconds before opening it. Jason's eyes finally fell on the stairway he had walked down on a few years back.

'What the…'

Jason rubbed his eyes to make sure he was seeing the correct thing. All of the stairs seemed to be embedded with different types of mana.

Jason stepped on the first stair and could see a huge block of red mana moving towards him. It pulled him towards down for a few seconds before spreading throughout the stair.

[ Hmm, your body was suddenly subjected to ten times the normal amount of gravitation force for a split second. Anymore than that and you would have been pulled through the metal and died. ]

'That's a reassuring thing to know…'

Jason continued to walk downwards and every stair ended up doing the same thing to him. Though the effect barely lasted for a second and he was able to move forward without any worries.

'Hmm, I don't understand why she asked me to hold my breath and keep my ears closed.'

[ Look directly in front of you and increase the mana input. You will get your answer. ]

Jason did as told and focused directly in front of him. He was standing on top of a lightning mana concentrated stair and had already experienced its pulling effect.

But the moment he increased his mana input, Jason was shocked to see that enormous amounts of mana were directly entering his body from his nose and ears.

The longer he inhaled, the more mana went inside his body.

[ If you had consumed this much mana in the past, you might have died from overconsumption. Not to mention that if you hadn't been walking together with her, there was a chance that you couldn't have been able to survive the pull.

After all, you were extremely weak as compared to now and you didn't have Hestia either. That was why Risa had created that teleportation rune inside your room. ] The system explained.

'System, I just realized something.'

[ What is it? ]

'That rune was never removed from my room.' Jason facepalmed.

[ … ]

Neither the system nor him had remembered that the teleportation connection between his room and the lab still existed.

If they did, they could have simply made use of it to appear in the lab instead of going down the stairs.

'Well, we have come all the way here so it doesn't matter.' Jason replied before walking down the final stairs.

He ended up in front of a door before facepalming again. The door was the same door that Risa had unlocked using some complex thing.

'I guess I have to go back to my room.' Jason sighed and started climbing again.

He went up the stairs and entered the house again. After appearing inside his room, he picked up a carpet placed on top of the teleportation runes.

The runes had faded over the years yet he could still see a few drops of his dried blood on top of the symbols.

Jason dripped some more of his blood on the runes and watched it get activated after a long time.

The light from the runes surrounded his body and immediately teleported him away. He reappeared inside the same room he had used back when he was trying to master the corrosive property of dark element.

"You came from the stairs the first time, didn't you?" Risa questioned in an amused tone.

She was currently standing near the extremely large table and seemed to be working on some sort of creature.

"I forgot that the teleportation runes were still present in my room. I came to the bottom of the stairs before seeing the locked gates and going back up." Jason sighed and came to stand beside Risa.

"And then you met the locked door and decided to go back." Risa added. "You know that you could have just called me and I would have unlocked the door for you?"

"…"

Jason couldn't help but wonder whether using too much thunder had short circuited his brain or not.

'Did it effect you as well? How can both of us act this dumb at the same time?'

[ I think I need to check myself for some virus. That's the most reasonable explanation. ]

'How would you even get a virus?'

[ Do I need to remind you that we just exchanged foreign divine energy as well as  mana from a being of another race recently? ] The system replied.

'Never mind. Go run a scan while I try to figure out what thing I will be blowing up next.'

[ Host, choose your words carefully… ]

'Damn it…'

Jason slapped himself on the cheeks once before focusing his attention on the table. Four metal cubes were lying on it.

They were colored gray, red, blue and green, symbolizing the four basic elements. Jason reached this conclusion since his mana vision was still turned on and he could see the same mana present inside the cubes.

"These are mana cubes. They simply store the mana for future use though they are pretty expensive to get a hold off," Risa explained. "These are the base for what your training will include."

Jason looked at Risa with a confused expression. His grandmother passed one of the cubes to him and smiled.

"Send a bit of your mana inside it." She instructed.

Just to be safe, Jason decided to use his dark mana. In case anything went wrong, at least he would be able to corrode whatever would go wrong.

'Huh?' Jason's eyes widened when he noticed the reaction taking place inside the mana cube.

Risa had handed him a red mana cube which contained fire mana inside it. Jason had injected a tiny amount of his own mana inside it.

The same small amount of mana and instantly spread throughout the fire mana in small particles.

It had mixed together with the fire mana and Jason now felt as though the fire mana belonged to him.

"The special thing about these four metal cubes is that they will allow you to use the four basic elements as long as someone charged them beforehand. You can ask any of your friends to put their mana inside them.

You will then be able to use that element for a limited period of time which usually depends on the amount of mana injected." Risa explained before taking the cube back.

She injected some life mana inside the cube and somehow dispelled Jason's mana from it. The fire mana returned to its normal state and Jason could no longer feel a connection with it.

"How did you do that?"

"I just threw your mana out of the cube with the help of life magic." Risa smiled. "Today I am going to teach you how to create a mana cube inside your body so that you can use it to cure injuries the moment you get hit by them."
