It's time to train with 'golem heart'(corrected)

In the middle of a group of 7 orcs, Mark could be seen with the sword, still in its sheath. When an orc was about to attack him, a magic circle appeared in front of Mark's hand from which an electric sphere the size of a soccer ball came out, which exploded when it touched the monster's head, killing him immediately.

As soon as he killed the first, he created another magic circle from which a light and a sound came out, which drove the orcs crazy. Seizing the opportunity, he began to launch explosive electric spheres that killed all the monsters.

"It will also be useful, but the load on the Falna is too much." -Said Mark breathing hard.

It was the third day he was exploring the 10th floor and thanks to lessons with Riveria, he had managed to update some spells. The first, 'electric dart', now had two forms, one that specialized in blast damage but was slow and the other specialized in puncture damage and was much faster. The second spell was 'flashbang', which didn't damage anymore Mark, but it lost a little in power.

The new spells were more powerful and faster to cast but needed more Falna, but that was okay with Mark, and the fact that he was using magic circles didn't mean he was going to get rid of his old method. During confrontations with people, he might trick them by using the name of different spells or just fire a spell when the opponent expects to see a magic circle.

"I'm no longer shocked by how you fight, but can you explain to me how you grow up so fast? " -Lefiya said without words.

These days she would follow him to the 10th floor where she would eventually give support but noted that Mark's growth rate made no sense. Previously he was hit several times by monsters, while today he was only slightly scratched.

"I think it's adolescence." -Said Mark as he collected the stones.

"Are you kidding me! We only take one year off! " -Lefiya said as she stepped on the ground.

"Well, from what I know elves mature slower, plus you are level 3, it's normal for my growth rate to be higher than yours." -Said Mark as he got up getting ready to go.

"For real?" - Asked still suspicious.

"Of course." -Mark nodded, but his mind said otherwise. -' No, I simply have a growth ability. '

Mark had spent a lot of time with this elf these days, so he didn't care much about talking to her or teasing her, especially with the reactions she displays every time. He also found out some things about her. She gets embarrassed easily when complimented, even if she seems angry as she is now, it's just a facade, she has a sense of inferiority towards others, and has a certain obsession with Aiz.

The first two were quite simple to understand. He understood that she had a sense of inferiority, from how she talked about others, while the obsession with Aiz...

'Let's just say that when he gets the opportunity to talk about her, she never stops.'

"Looks like you'll be busy for a while." -Said Mark, as he went up to the upper floors.

"That's how it seems. So behave yourself and don't go down to the 10th floor alone. " - She said as if she were his teacher.

"Yes, yes." -Said Mark, with a simple wave of his hand.

After the 18th floor incident, the Loki Familia decided to do some research on the appearance of Evilus and the new species.

Evilus was an extremist group, which appeared after the weakening of the Familia of Zeus and Hera. The group's goal was chaos and destruction and they had the plan of destroying Babel by releasing the monsters inside the dungeon. Fortunately, the guild, along with the various more powerful Familia like that of Loki and Freya, managed to destroy most of them, but it seemed that some had remained alive.

After exiting the dungeon, he greeted Lefiya who had to be present at the meeting to talk about the research they had to do. Now alone, Mark first made his way to the guild where he exchanged the stones, and later, he headed in a different direction to that of the villa.

[Where is Host heading?]

'With the fact of exploration, I have no one who can help me improve, so I decided to practice with a skill, which I have feared for too long.' - Mark replied, as he climbed the city walls.

[Are you sure Host?]

'Sure, don't you also think, that now is the ideal time.' - Mark said, as he looked at the corruption value he had.

(corruption 3%)

According to the Guide, the reason the corruption had decreased was thanks to the Selene fragment, which appears to slowly repair the damage. The reason it took so long to start the repair was because it still hadn't adapted to Mark's soul.

Even if the fragment helped him to repair his soul, there were still limits. The first was that if the damage to Mark's soul were great, he would need more fragments, and even if his soul was repaired, the psychological change would remain.

Let's take the case of the murder of the killers, who came to him. Mark felt nothing when he killed them, thanks to the corruption, but even if the corruption disappeared, his mentality would change. He might feel something during the act of killing, but he would have no problem doing it anyway.

Arriving in one of the deserted areas of the city wall, he took a deep breath to calm his thoughts. The reason he came here was because of the peace that was present, which allowed him to concentrate.

"Guide now I will activate the ability, when the corruption rises, notify me immediately." -Said Mark.

[Affirmative]

"Well, 'golem heart' activated." -The activation of the ability made Mark's world gray.

--- Pov Mark ---

Opening my eyes, I was greeted by a world without colors and warmth, as in the past I seemed to have lost any kind of concept. Trying not to get lost in my thoughts, I managed to keep my focus.

<Specify the objective.>

'training.'

<Target request confirmed.>

It was a strange sensation, it seemed to be talking to myself and at the same time with another person, and what I was experiencing was incredible. My thoughts flowed with astonishing speed as if nothing was blocking them.

Keeping my mindset still intact, I began to perform simple actions, such as walking, and then moved on to more complex ones such as running and jumping.

'Well, I still have complete control.' -I thought.

Then I decided to switch to the use of magic and when I thought about launching an explosive-type electric magic, the magic circle immediately formed.

'As I imagined, my mental abilities have increased in a suspending way.'

The ability to focus 100% was what I was aiming for. It would usually take me at least a second to create a magic circle, but this time I was able to recreate it almost instantly.

Then I decided to test my mind further and decided to practice shadow boxing and my opponent was none other than Tione, the only one I saw fighting most of the time.

It was amazing to see the figure of Tione in front of me, it looked absolutely real. Unsheathing the sword, I charged without hesitation, but the moment I tried to hit Tione's body, she dodged, and without giving me time to react, a kick hit my neck, breaking it.

'I'm dead.' -I thought as I lifted myself off the ground and touched my neck, only to see that everything was okay.

'What a fantastic thing the human mind.' -I thought in amazement. If I had my human side I would be terrified of the experience I just underwent, but all I felt now was just interest.

Later I tried again to attack Tione in different ways, even with the use of magic, but in any case, it ended with my death.

'How far had I arrived? I think I lost count at 30. '

Rising again, I was ready to attack when my vision darkened for a moment and then returned to normal.

[Host, corruption has increased.]

As soon as I heard the help voice, I disabled the ability without hesitation.

'Skill deactivation.'

When the ability was deactivated, I was again flooded with the colors and heat emitted by the world, but I knelt when a strong weakness flooded me.

" 'Heavy Breaths', Guide, How long have I kept the ability?" -I said still tired.

[10 minutes. What the host is experiencing now is the fatigue and mental stress of the constant fighting.]

"Haaa I understand, to me, it seemed a lot more. Give me the report. " -I said, as I managed to get up again.

[During the entire period of activation of the skill, the mentality of the Host has always been stable, but by the time 10 minutes have passed, there was an imbalance, which led to an increase in corruption.]

"So my limit is 10 minutes?" -I asked quite satisfied.

[10 in case your mind is in the best state. In a fight where there can be countless unexpected events and where mental stress is high, I don't know.]

"This makes sense. However, I will continue to practice like this with 'golem heart'. When I see that I have no problems managing it, I'll switch to using it in fights as well. " -Said Mark while stretching the body.

"Right, how long will it take to repair today's damage?" -Today corruption has increased by 1%, so I was wondering how long it would take to settle down.

[24 hours, this is because corruption is less than 5%, otherwise it would take longer.]

"Perfect, it means that I can train every day without having to worry." -I said, as I approached the ledge of the walls.

"You know, I always have a head full of problems and worries, that I had never stopped to look at such a simple but at the same time beautiful landscape." -I thought aloud as I watched the sun slowly set over the plains.

[What do you think of this world?]

"Initially I hated it. A place where everything is foreign and I never know what could happen, but with time, I have begun to appreciate it. Here I was given the opportunity to be reborn and bring Selene back to life, an opportunity that I could never have expected. I just hope that Selene can find happiness here too." -I sighed as I walked away from the darkened walls.

[Do you think your partner won't like it?]

"I think she will find this world very beautiful too, but it will be difficult to settle in. This world is full of dangers behind its beauty, that's why I want to get stronger. I want to be so strong that she will never have to worry about her safety and make sure that the future is only in my hands not to others or luck. " -I said holding out my fist with force.

'Wait for a little longer Selene, just a little longer. ' -Was my thought as I headed for the villa.
