Nie Lie who saw the whole ordeal doesn't know how strong will his brother become in future with this cultivation technique. He also thinks whether it will be his major mistake in this life. But his instincts says to him it is for good, so he leaves his brother alone and went to the forest as it is time for Xiao Ning'er's Treatment.
Nie Long sat alone in the Dorm checking his demon spirits in his Soul Realm

Metallicana - Origin Form
Law of Metal - Metal is one of the five basic element which holds all the other elements together to form this world although it may seem that other elements are seemed necessary for life compared to metal but metal is the only element which holds the other elements towards itself to form land, ocean, air, Metal is also be termed as an Earth Law....
Weisslogia / Skiadrum - Origin form
Law of Light / Darkness - Nie Long imagined same as Nie Lie did in the original and cultivated by searching light in darkness and darkness in light and started to follow the same procedure as he started to have his own understanding of these two laws are the like the two sides of a coin. One is presence and the other is absence...
Mercphobia - Origin Form
Law of water - Water is born from fire. But also the same water nullify fire. It has different forms in different temperature and pressure. It is gentle but also cruel and Nie Long slowly understands the laws of water ....
Zirconis - Origin form (Lightning) (A.N: I just selected Zirconis for Lightning Dragon)
Law of lightning - Lightning is the very basis of Energy transfer. All life forms has lightning energy or also known as electrical energy but in a dormant form which can be released by the exciting the electrons in them ....
As it is shown all the laws are the very basics of physics and slowly moving towards advanced laws of the particular elements separately and it becomes a deep topic which is meant to be learned something new over and over again. At one Particular point All the Laws are interconnected with Each other in a pattern
As he saw the dragons in his soul realm he saw all the they were clear and powerful just the presence shows their might. But Acnologia is the brightest of all the Spirits. The Aconologia it comprises of Chaos, which took Nie Long more than 10 years to reach his current understanding of the Chaos laws.
Aconologia - origin form
Nie Long ' Chaos Law - What is Chaos!? ' No matter how hard he tried Nie Long was unable to comprehend this law no matter How hard he tried. Year after year where three years passed by as he slowly started comprehending the other laws but he was unable to understand the Chaos.
One day when he was trying to figure out Aconologia and what is special compared to others. He had a realization, the main point is it can consume all the element in existence, he slowly came to realize that Chaos is collection of all energies in its primordial form i.e it is the mother of all elements. In the birth of the universe Primordial form i.e Chaos births all the other elements and in the Destruction of a Universe all the elements return to its Primordial form which is Chaos.
Chaos is the embodiment of both creation and destruction. And this is also the reason for Aconologia to move towards the character loving Destruction in the Fairy Tail World. Nie Long gradually understands Chaos more and more. with this his other laws understanding also become deep along with it.
Aconologia - Majestic Black Dragon which just shows the embodiment of destruction.
Arc of Time - Time Law
As Chaos Law understanding increases, Nie Long found an important factor. i.e his time law never improved. He tried to understand why time is not in the element list since Chaos is the primordial of all elements. Then he became sure that time is independent of Chaos. So he thought then how the time can be understand and what is the element which the time depends upon. Slowly found another element which is independent of Chaos - Space/Void.
Nie Long was enlightened, he started to understand time, he started comparing Time & Space with water." If Space is still Water then time is moving Water. Movement of Space is Time " Which explains rotation and revolution of planets . Expansions of Universe . And this further made his Conjecture true. "
When he used his Arc of Time magic, he was able to move the Time of a certain object easily compared to a small area. The amount of power increases when the area increases . This is the reason Urtear sacrificed all her powers and existence but it can be moved only one minute backwards for the Entire World. As She was trying to reverse the flow of the entire planet. It can be easily explained by energy required to reverse a tap water flow to reverse the river water flow backwards.
Like that Nie Long used Thirteen years to consolidate the demon spirits and his Arc of Time magic. This also gives great cover from Dark Guild recognizing his talent while he is building a strong foundation for his spirits without anyone interfering with his affairs.
