When she said that all three of them agreed although Dae-Seong was terrified because it definitely looked like she wanted to get revenge for what he did to her and so he was nervous in receiving training from her, so he slowly went up to her.
But to his surprise, she was extremely happy and was genuinely excited, she kept complimenting him for his skills and being able to use her skill and so Dae-Seong was confused but then Leonard chuckled and then went up to him.
Then he said, "Centy respects people who are strong and your definitely strong, Dae-Seong." he said as he smiled but then he quickly looked away from Dae-Seong and so he was confused, suddenly Centy went up to him and grabbed his shirt.
Centy dragged him into a more open space and once she did she threw her scythe sideways to really level the ground and environment so it would be perfect for Dae-Seong training and then suddenly she threw a smaller scythe at him.
[Bzz, The System wishes for Host's growth, the system will allow you to copy their origin energies without any costs or requirements, it would only be the growth of the host but the pain will still be there, do you wish to accept this gift?]
Dae-Seong was surprised when he saw the message but he then said, "I accept" quietly so they don't hear it since they don't see Bolt or the system except for Leonard and when he did this he set up his pain tolerance skill so he wouldn't feel a thing.
Once he did that he first felt a surge of power in his body and even at the max level of the pain tolerance skill, he was still feeling a lot of pain that made him want to faint and pass out but the energy still wasn't allowing him to do that.
Although Dae-Seong was still able to move so he decided to go through the training still since he still wanted to get stronger and so he was ready to listen to whatever lesson that Centy was going to give but she just held her scythe as she smiled.
After smiling she said, "My training is practical, get ready." she said as she disappeared as there was a trail of orange energy of where she was and she appeared above Dae-Seong as she was just floating in the air, she created multiple slashes in the air.
It was made into some sort of energy projectile attack creating a slashing effect that was going to hit, Dae-Seong but then suddenly he smiles as he disappears as well and appears beside Centy and there is also a trail of orange energy.
Even though it was a bit weaker, it was still the same skill that Centy just used and as Dae-Seong held the smaller scythe, he covered it in every single scythe origin energy he had and then created slashes similar to Centy's midair.
Except, he wasn't able to fully copy Centy's floating skill but he was able to glide from using what he saw from Centy's movement and the three people watching were amazed and they were just getting excited to teach him except Leonard.
While they were watching, Leonard talked to Bolt as he said, "Hey, Tiny God, if you could please not show Dae-Seong his natural skills that he learns and just show it to me, he might become reliant on whatever it is since it's from the system thingy.".
[Bzz, Guardian "Leonard" is correct, it would indeed help the host grow further if he does not know about this feature but there is on thing your wrong about in your statement, it's that natural skills are something when the hosts learns their complete principles by himself.]
[Bzz, The skill and abilities given and made by the system are activated when the host thinks that he wants to use the skill but natural skills need the host to completely have the control so he needs to know the skill's details completely.]
This surprised Leonard since if what Bolt was saying is true that means Dae-Seong was already able to understand his skill just after seeing it even though he hasn't even properly trained with it and he was able to use it without any restraints.
Leonard was a bit jealous of his talent but there was nothing he could do but watch the monster grow to an even stronger monster than what it once was so he was a bit excited and he then checked back at Centy and Dae-Seong training.
There was nothing that much to be surprised about but then suddenly multiple panels appeared in front of Leonard and it was giving the information on Dae-Seong's skills and growth. nearly everything that was needed to train him proper.
[Bzz, Guardian "Leonard" please train the host well, this feature is a special feature that only is given to the role "Mentor" of the host to be able to perfectly train him to his strongest form, don't worry you won't be doing this for free.]
As Bolt said that a huge surge happened inside of Leonard's body and when the surge was over his energy improved another 10% which sounded small but even increasing it by 0.01% was already difficult so increasing it by 10% was a godly speed.
Right after receiving his payment, Leonard's was serious about being Dae-Seong's mentor since if Bolt could give him power, he could definitely take it away and he definitely didn't want to get on the System's and Bolt's bad side and so he was going to do it properly.
He started creating a training according to the information given to him by the system and he could see everything that he needed to improve although there wasn't even a single weak thing about him, an imbalance was the biggest problem he had.
It was that his stats, skills, body, abilities and a whole lot of other things weren't balanced and it was definitely not helping Dae-Seong one bit, his skills and abilities aren't allowing his stats or body to keep up with his overuse of his skills and abilities.
Since he doesn't train his body well since he relies on the system using body skills and abilities to improve his body without any training required so Leonard was creating a hellish training to improve his original body to be stronger.
Which as he was doing this Dae-Seong and Centy were still training although it looked like Dae-Seong was now struggling to keep up with Centy, Leonard could see that he improved a lot in that short time and even learned more natural skills.
