The question then remains. How should he develop? There are so many parameters that exist such as distance, size of object, level of precision, power of vibration, etc.

All these parameters would affect and determine his limitations. Thus, Feng Ye decides to first eat and then experiment to determine the current limits of this vibration ability. Perhaps, he would get some insight on how he should develop it.

Feng Ye arrives at a restaurant and takes a seat. At this time, he notices a gla.s.s of water a few tables away and tries to vibrate the water within it. He only planned to make it vibrate and barely noticeable. Next, he continues the same on a gla.s.s of water further away.

A few minutes later, he had determined that it requires more mental effort and energy to vibrate at a further distance. The same probably applies to the size of the object.

So, for an extremely heavy and large object which is really dense, it will probably take more effort to vibrate it when compared to a smaller one. The same would be true for particles at an atomic scale. It will require a ridiculous amount of energy and mental strength to vibrate it it enough to disrupt bonds.

Therefore, the two extremes of very large and very small is not possible for him at this time. A large object requires more overall strength, while a smaller one would require more strength in the control and precision of the ability.

As the food he orders arrives, he decides to inquire s.h.i.+ra to get her opinion.

In Feng Ye's mind, s.h.i.+ra had already taken a look at Feng Ye's approach to determining the limitations of his ability.

As Feng Ye's form appears across from her, s.h.i.+ra says, "I took a look at your trials...most likely it will be similar to your Spiritual Awareness ability. You'll need to continuously train and use it. The more you use it, the more experience and insights you would gain. As your ability is also dependent on your mental strength and effort, you will need to continuously use Spiritual Awareness to strengthen your mental const.i.tution. You will find a natural increase in ability and development if you continuously exercise these abilities."

Feng Ye decides to actively use both his vibration and Spiritual Awareness abilities in conjunction with each other during the trainings that he would have to undergo the next few days. He decides to stop the experimentation at this time until after his attempt in exchanging with Kotori's sister.

He'll need all the energy that he could get. Thus, it is important to not continuously experiment at this time and mentally tire himself out.

As he eats the meal, Feng Ye decides to figure out what kind of applications this ability can contribute to him at this level. Currently, he won't be able to slow down the vibrations of particles or to make an area's temperature cool yet, nor could he control the vibration intensities at the molecular level. As of now, he can only make objects vibrate which may give off some heat. After some thinking, he remembers that sound is a vibration that typically propagates as an audible wave of pressure. The development of vibration of his sound can be done.

Sound seems to be easier to manipulate compared to at a molecular level. As he will be able to simply provide the sound and amplify it or decrease it with his vibration ability. This may also open up the development direction of sonic or ultrasonic weapons. He can potentially emit high power sound waves which could disrupt the eardrums of a target and cause them to experience pain or disorientation.

If he had a weapon, he could also apply these ideas to it.

He is enlightened Feng Ye immediately tries one last trial before stopping for the day. He immediately heads to the restaurant's washroom.

Once he arrives and notices that no one else is there. He mumbles softly, "Hi". He uses the vibration ability to amplify the sound. The "Hi" can be heard as it echos within the washroom.

"Nice, this might work. Although, it does result in some mental exhaustion, I should be able to utilize this ability often and at this scale. Once I head outside of the complex, I'll need to try to experiment whether I can concentrate and emit a high power sound wave."

Now, Feng Ye is equipped with Spiritual Awareness which will complement his vibration ability. He would be able to disorient his opponents and be able to potentially develop the vibrations into sonic weapons. If he is attacked and needs help, he could also utilize the vibration ability to amplify his yell for help. He looks forward to the day he can develop and use his vibration ability to create a domain with a controlled temperature. Other applications that he could use when this is fully developed include causing vibrations in the earth which may result in an earthquake, or ultimately breaking the molecular bonds, thus, destroying an individual's existence. Naturally, it isn't all destruction. He could potentially use sound to ease the mind's of individuals who are confused or target certain objects or cells and dispose of them.

The fully satisfied Feng Ye heads out of the washroom and back to his table. He quickly finishes his meal, pays the bill, and heads to Kotori's rental room where they had decided to meet up earlier the night.

As he arrives in front of Kotori's rental room, he knocks. Kotori opens the door. "h.e.l.lo Feng-kun, are you ready?"

"Yeah, let's go." He replies.

Kotori leads Feng Ye to the elevator and they make their way back to the ground floor. After exiting the complex, Kotori leads Feng Ye to the metro line which is on route to the Aven Inst.i.tute of Technology.

They arrive at the main campus shortly as this late at night, there's aren't as many pa.s.sengers, thus, less stops that had to be made.

Kotori leads Feng Ye into an elevator and presses the lowest level available. "We will need to meet up with Akeno-san shortly. Just follow me and don't wander around."
