Since he couldn't do it, but others could, Kevin naturally felt deep admiration.
Kevin pulled back his fleeting thoughts, looking at the three who were as excited as if they had received new toys, and didn't disturb them too much.
Wasn't he like this back then too?
After the three had gotten used to it for a while, Kevin continued: "Above the Four Major Principles, there are also the Seven Great Techniques,"
"They are various application techniques of Nen Ability. However, for now, you need to first master the basic abilities, and I will teach you later."
"Do you understand now? You can first feel the changes in your bodies, and from now on, you must undergo Nen Ability training every day."
"Of course, physical training cannot be relaxed; this is the foundation of everything, but now you need to pay attention to the balance between the two."
Saying this, Kevin simply started training together with the three of them.
Because at this stage, he also needed to shift his focus to the development of "Nen."
In the past six months or so, he had fully unleashed his tough physique, training madly to strengthen his physical fitness, and had now laid a solid foundation.
Now, he wanted this tough physique to unleash a sufficiently massive amount of Nen.
The training and development of Nen Ability is not something that can be completed overnight, but rather a long process.
Besides training with the three, Kevin began to invest more time into "Nen Ability Development."
Nowadays, he was adept at materializing "syringes"; materializing a syringe was effortless for him.
According to Bisky's understanding and explanation of Nen Ability:
The essence of materialization is the strengthening of the rules of existing objects; it is an ability to establish the rules of items.
Suppose someone's materialization ability is to materialize a balloon.
Then, this person can extremeize the inherent characteristics of the balloon itself, and even endow the "balloon" with some functions it didn't originally possess.
For example, a balloon has the characteristic of floating, so its floating ability can be strengthened, allowing a regular balloon to carry people into the sky.
Or, if a balloon can explode, then its explosive power is strengthened, making the balloon directly turn into a bomb.
And establishing rules is giving the balloon some abilities it didn't originally have.
For instance, stipulating that the balloon they materialize has a scanning function, capable of seeing things in place of eyes.
Through restrictions and vows, the balloon can acquire this ability.
Or giving the balloon the ability to sense danger; as long as danger approaches, the balloon will explode, serving as a warning.
Such as these, are the characteristics of the Materialization System Nen Ability.
Kevin looked at the special syringe in his hand, which he had handled so much it was almost polished smooth.
First, he clarified that this syringe was essentially a derivative of his Nen Ability ["A Moment's Dream"].
Its purpose was to strengthen and supplement the details of ["A Moment's Dream"].
As his body continuously grew stronger, Kevin's Nen had reached 21000, and the available memory capacity was sufficient to support him in constructing an additional derivative Nen Ability.
After all, this wasn't some main Nen Ability; it was an accessory and didn't require much.
Currently, the basic conditions for guaranteed success were already met.
Next, what Kevin needed to do was clarify what functions he hoped this syringe would possess.
His goal was: to further strengthen the efficacy of the potions he made.
Since this was a Nen Ability he constructed himself, he had to clearly define the effect the Nen Ability was to achieve, as well as the specific method and degree of strengthening.
After thinking, Kevin decided to strengthen the syringe's injection ability.
He hoped that there would be no need to deliberately aim for a specific part for injection; as long as the syringe was inserted into the body, the potion inside could be immediately injected into the body and quickly spread to take effect.
This point didn't need to be too deliberate, as his potions themselves also had this ability.
Then, Kevin also wanted to strengthen some abstract concepts of the syringe.
The function of a syringe is to allow medication to enter the body, achieving effects that cannot be attained through oral administration.
For example, a medication can be taken orally or injected; through injection, its effect is often better and takes effect faster than oral administration.
This is a normal, logical, and realistic issue.
