Heaven Crystal

The **Heaven Crystal** (通天合晶 *Tōng Tiān Hé Jīng*) is a powerful artifact in *Guardians of Night* and a major driving force of the series's plot. It is a red crystal of great power, capable of granting an individual's wishes when absorbed by them. For this reason, it is desired by the Department of Night, Underworld and Sun.

## History

The Heaven Crystal has appeared less than five times throughout history. The most recent recorded appearance of it before the story was in 140 A.D. in the Qiao County (谯郡 *Qiáo Jùn*) (present day Bozhou) during the Han Dynasty. At that time, the Heaven Crystal formed and subsequently split into a larger piece and a smaller piece. The larger piece was acquired by Cao Cao, who used it to rise to power as a warlord. The smaller piece was acquired by Hua Tuo, who used its power to become the greatest physician during his time.

## Formation

In the "Middle-Earth Reality", everything in the world gives off spiritual energy. A stroke of serendipity will allow all the spiritual energy to converge into one place. The moment they converge, with a low chance of happening, the energy will condense and form the essence of the universe. After compacting together, requiring an incredible stroke of luck, the essence will take a physical form. Since the essence's physically appears similar to a crystal, it is called the Heaven Crystal.

Due to the irregular flow of the world's spiritual energy and the nigh-impossible formation process, the Heaven Crystal is an incredibly rare event that may not happen even once in a thousand years.

Even if the Heaven Crystal does form, it will initially manifest itself as incomplete shards in various locations, usually coming in sets of seven. Its energy can only be sensed when its shards are within close proximity of each other and neither are within enclosed spaces, causing them to resonate with one another and excite their energies. Otherwise, by itself, a single shard would appear as a normal crystal. When resonating, the Heaven Crystal shards glow depending on the distance between them, becoming brighter as they are closer and vice versa. Once close enough, the shards will pull themselves together and permanently fuse, forming the Heaven Crystal itself or larger parts of it.

## Usage

The Heaven Crystal's fragments cannot be absorbed by any means. Only when all its pieces are fused into one can the crystal be absorbed. However, the power of the Heaven Crystal is not infinite.

The wish-granting ability of the Heaven Crystal can best be described as an enormous wishing bottle. By principle, it is capable of granting any wish, but in reality it depends on the wish's "size". Every wish has an appropriate size; for example, the wish of wanting a luxurious car would be the size of an apple, while the wish to become ruler of a city would be as large as a truck. In essence, the Heaven Crystal possesses an enormous "volume" of wishes and is therefore capable of granting wishes of enormous size.

When obtained by Cao Cao and Hua Tuo in 140 A.D., the two both used their pieces of the Heaven Crystal to grant their wish. Having the larger piece, Cao Cao wished to unify China, while Hua Tuo wished to rid the world of suffering with his smaller piece. Despite the Heaven Crystal's immense wish volume, it still has its limits. As a result, despite having the larger piece, Cao Cao was never able to unite China in his lifetime, with his descendants fulfilling his wish instead. Due to having the smaller piece, Hua Tuo's Heaven Crystal was even more limited and was unable to grant his wish, instead giving him medical techniques that allowed him to cure those he met.

## Story Relevance

The Heaven Crystal appeared before the Double Devils Arc, almost 2,000 years after its last appearance. The Department of Night sent out its guardians to find pieces of the crystal so they can obtain it for themselves, but so does the Underworld and the secret organization, Sun.

Since the two Demon Lords joined the Department of Night and became guardians, Wang Shengli and Yan Wen came up with a point system for the guardians. The guardian with the most points when all the fragments are acquired will have the complete form of the Heaven Crystal.

The secret organization, Sun, also wants to obtain the Heaven Crystal, but their plan is to let the Department of Night find all the fragments of the Heaven Crystal for them while slowly weakening the organization by killing some of its members off but leaving enough members to find the fragments. They also codenamed the Heaven Crystal fragments that have appeared for easier recognition. Liu Damao, leader of Sun, split his Heaven Crystal fragment in half, disguised one half of it as a complete fragment, and gave it to the Department of Night to secretly monitor their collection and location of the other fragments. The other half, after a series of events, ended up in the hands of the Yan Wen and by extension the Underworld.

## Current Status

Currently, 6 pieces of the Heaven Crystal have been found and acquired by the Department of Night and the Underworld respectively. The Department of Night holds 4 and a half pieces, while the Underworld holds 1 and a half pieces.

Due to Liu Damao splitting up Crystal 4 and disguising each half as the complete fragment, there exists a discrepancy in information between the Department of Night and the Underworld. As a result of Yan Wen believing Crystal 4B to be the fifth fragment and hiding it from Wang Shengli, she mistook Crystal 6 to be Crystal 7, the final piece.
