Inside the training ground, Kevin's Nen was completely depleted. He immediately sat cross-legged on the ground, panting heavily, with beads of sweat rolling down his body.
Increasing Nen is much more difficult than enhancing physical fitness. It requires a gradual, deep excavation process.
Bisky had taught Kevin various methods, and he was trying them out one by one to find the one that suited him best. During this time, he had made considerable progress.
Strong physical fitness indeed brought many advantages, such as being able to excavate more Nen.
After all, there is a limit to the capacity of Nen a body can hold based on physical fitness.
The better the physical fitness, the more Nen can be contained and excavated.
As one gets older, the opportunity for excavation also increases, but similarly, if one becomes elderly, their strength will also decline.
And Kevin's physical fitness was extremely strong, making it easier for him to excavate a large amount of Nen in the early stages.
It's like two pieces of land both have mineral veins, but one piece of land has the veins buried deep underground, while the other piece of land has the veins even exposed directly on the surface.
Using the same manpower and time to excavate, naturally, the latter piece of land will yield more Nen.
Therefore, he was currently in the rapid growth stage of the early period. This kind of training, where he could constantly feel his own progress, fascinated Kevin.
Although the fastest way to improve was by using medicine when its effects were best, the feeling of strength excavated from within oneself through effort was different.
Recently, he had almost become a regular at the training ground, with training time occupying most of his day.
You know, the thing he used to spend the most time on was researching various medicinal materials to develop and produce new potions.
After resting for a moment, Kevin wiped off his sweat and went to the rest area.
Kurapika and the others had already been resting there for a while. When Kevin came over, he clearly heard their casual conversation.
At this time, these little guys were searching for various gem information online and discussing their metaphorical meanings.
"Uncle."
Pairo smiled and greeted Kevin as he walked over.
Kevin nodded and looked at everyone.
"Your Training of the Four Major Principles is almost done. At this stage, I will teach you more advanced techniques.
"Once you are familiar with them, I will conduct your system identification. I'm sure you've been looking forward to it for a long time."
Hearing this, everyone's attention was immediately drawn, and they all stood up.
Even Neon, who was off to the side, came over curiously to listen. Although she might not necessarily learn, and with her current level of Nen control, she couldn't use these techniques anyway.
But she was very interested in what system each of them would be.
The few of them stood in a neat row.
Kevin walked to the whiteboard and wrote down different symbols on it.
"The so-called Seven Great Techniques, they are respectively—"
As Kevin explained, everyone nodded, finding it easy to understand.
Essentially, these were extensions of the basics.
In fact, even without Kevin's explanation, after mastering a certain ability, a normal person would also think about whether these techniques could be achieved during training.
It's just that they might not be able to think comprehensively.
Therefore, the so-called Seven Great Techniques were likely naturally derived during training and actual combat.
Then someone summarized these things and turned them into systematic learning knowledge.
"At this stage, you can't be required to master every technique proficiently like you were during the Four Major Principles training.
