Chapter 30: Zone

What is Zone Exclusion?

Zone exclusions are a range-containing environment that are created and realized by life-force energy. Activating this type of high rank technique uses a lot of life-force energy so that would mean you would be able to use this technique once a day. If the ZE is activated, anyone who is inside the zone of exclusion will be forced out. It completely depends on the user, Zone Exclusions could also operate on a smaller scale, targeting a single individual or small group of people instead of targeting a larger zone. The idea of "Zone Exclusions" is that they are designed to keep people out of a specific area, so if someone is planning to attack, then the idea behind Zone Exclusions is that they would activate the technique to essentially "exclude" the person planning to attack from the area that they are defending. Shortly, the user would activate the Zone Exclusion to prevent the attacker from entering the zone of defense. In addition to these, techniques deployed in the range of Zone Exclusion are guaranteed to land.

What is the curse trying to do?

If the Curse used "Zone Exclusion: Torrential Thunderclap of Lightning", it would essentially create a Zone of Exclusion that would be filled with torrential lightning. This lightning would continuously strike and rain down onto everyone within the zone, effectively keeping them out while simultaneously doing damage. Anyone inside the Zone of Exclusion would be continuously struck by bolts of lightning from all directions and would not be able to enter due to the constant lightning strikes throughout the zone.

What could you do most effectively if someone used Zone Exclusion against you?

The most effective way to deal with a zone exclusion is to use your own Zone Exclusion against it. When there are multiple Zone Exclusions activated at the same time, the stronger and the more refined one will overwhelm others. Essentially reigning supreme against other zones.

After the technique is activated, Yagami gets forced out of the curse's range. Right afterwards, the bolts of lightning begins to strike from above. They are originally guaranteed to land but since they are inside a forest, the lightning bolts that were automatically directed at Yagami hits the trees instead, starting a fire. The fire spreads rapidly and begins to envelop the area, creating a dangerous and chaotic environment. With a forest fire and lightning bolts striking the area, Yagami now faces a difficult situation, as the intense flames and lightning around him pose a serious threat. "Now you are as good as ashes!" the cursed spirit yells and continues, "I will bury you alive you hear me!"

"I appreciate your willingness to kill me so much but I have bad news for you." he says and continues speaking, "You are far too weak to pose me any threat." Hearing this, the cursed spirit begins to fume from rage and yells, "I will fucking kill you, you fucking egoistic kid!"

The curse directs the lightnings right at Yagami himself this time, using the guaranteed hit effect.

I wish Yose was here to watch this. He would've loved to see this high level of a methodology fight. At this point, I am done playing around with this guy. Time to get a little serious.

Yagami takes off the blindfold from his right eye. Revealing both his eyes to the moonlight around them. He makes a handsign with his right hand and utters.

Zone Exclusion: Starforged Lunar Abyss!

What happened? Was my zone exclusion suppressed? I can't...move! I can't do anything!

With a short laugh, Yagami begins to explain and slowly walking to the curse meanwhile.

"'Starforged Lunar Abyss', essentially creates a Zone of Exclusion which uses the gravity of the Moon as a means of excluding people from the region. The Moon's gravity would become extremely strong within the Zone of Exclusion, resulting in anyone who attempts to enter the area being instantly pulled back out due to the strength of the gravity field. Additionally, the gravity field within the Zone of Exclusion would also cause any objects or materials within the zone to become severely distorted or even pulled towards the sky. In other words, the Zone of Exclusion would become a massive gravity well, pulling in everything around it and rendering it almost unplayable within the zone. The distorted environment would make it difficult for anyone who is caught in the Zone of Exclusion to move around or fight efficiently, as they would be constantly being pulled and pulled in different directions due to the immense gravity field. Any movement or attacks that someone attempts to make would be severely reduced and slowed due to the sheer amount of gravity in the area, making them easy targets."

"You being weaker was never an insult. I was merely stating the reality. It was fun, but I will stop here before you go insane. I will question you myself when you wake up." Yagami hits the neck of the curse real hard, knocking him out cold. Leaving Yagami to deal with the forest fire.

"Didn't expect him to lose this easily. Should we help him?" Young Lord says from distance to his ally.

To be continued...

How does Yagami's Zone Exclusion work exactly?

At its core, Yagami's Zone Exclusion "Starforged Lunar Abyss" is a technique that utilizes the gravitational pull of the Moon to exclude anyone from a specified area.

To mathematically explain this, we can refer to the gravitational equation for objects, which is:

F = G (m1*m2)/r^2

Where F is the gravitational force between two masses, m1 and m2 are these masses, and r is the distance between the centers of these masses.

Applying this equation to Yagami's Zone Exclusion, we can calculate the gravitational force between the Moon and someone entering the zone of exclusion. Let G represent the gravitational constant, which is roughly 6.67 x 10^-11 newtons per kilogram per square meter.

m1 would represent the mass of the Moon, which is roughly 7.35 x 10^22 kilograms.

m2 would represent the mass of the person entering the zone, which would vary depending on individual factors such as their weight and size.

In this example, let's suppose that the person entering the zone has a mass of roughly 70 kilograms. With the variables in place, this equation would become:

F = 6.67 x 10^-11 newtons per kilogram per square meter x 7.35 x 10^22 kg x 70 kg / (distance between Moon and Zone of Exclusion)^2

Plugging in all the values and units and simplifying the equation, we arrive at:

F = 4.29 x 10^16 newtons / (distance between Moon and Zone of Exclusion)^2

For the sake of simplicity, let's assume that the distance between the Moon and the Zone of Exclusion is around 400,000 kilometers. Plugging in this value into the equation for gravitational force, we get:

F = 1.71 x 10^14 newtons / (400,000 km)^2

To make this equation even simpler, let's approximate the value for gravity to "10^14 newtons".

With this simplification, we arrive at:

F = 10^14 newtons / (400,000 km) ^2

Now let's rearrange this equation to find the value of the force that would be experienced by someone entering the Zone of Exclusion.

10^14 newtons / (400,000 km)^2 = force experienced by the person entering the Zone of Exclusion.

Multiplying both sides of the equation by (400,000 km)^2, we get:

10^14 newtons X (400,000 km)^2, / (400,000 km)^2 = force experienced by the person entering.

Plugging in the simplified value of 10^14 for gravity and multiplying this by (400,000 km)^2 gives us:

10^14 newtons X (400,000 km)^2 = force experienced by the person entering

Simplifying the expression gives us:

4 x 10^19 newtons = force experienced by the person entering the Zone of Exclusion.

To put this into perspective, here are some values that are equivalent to 4 x 10^19 newtons:

1- The total weight of all humans on Earth is roughly 5.6 x 10^19 newtons

2- The average weight of an adult female elephant is about 4 x 10^19 newtons

3- The force necessary to lift a fully loaded and parked large airplane is about 4 x 10^19 newtons

In Conclusion, the Zone of Exclusion created by Yagami's "Starforged Lunar Abyss" technique generates a gravitational force that is equivalent to the weight of all humans on Earth, or similar to the weight of an adult female elephant and also a fully loaded airplane.

This means that anyone who enters the Zone of Exclusion would immediately experience this immense force, making it practically unplayable inside the zone and near impossible to navigate, walk, or fight.
