Background
The Earth Book was nurtured beside the cocoon formed by Li Zhengyuan's true spirit and Earth Suluo True Primordial Qi. The Earthly Dao concealed the cocoon within a blessed Cave-Heaven, where the Ginseng Fruit Tree also took root; Zhen Yuanzi was eventually born with both the Earth Book and the Earth Embryonic Membrane among his innate endowments. 2 25
As Zhen Yuanzi's accompanying treasure, the book is closely tied to his mastery of the Earthly Dao. By the time he resumed his southern journey, it was the only one of his principal treasures to be fully refined and linked to his fate. 19
Abilities & Functions
Earthly Dao Authority and Geomancy
The Earth Book is attuned to the Primordial World's earth veins, terrain, mountains, and rivers.
- Records the great and small earth veins, mountains, and rivers of the Primordial World, allowing Zhen Yuanzi to identify Tang Mountain at a glance. 24
- Connects with earth veins and guides them to restore disordered land. 16
- Enables Zhen Yuanzi to alter terrain, reduce Earth Sha qi, redirect earth veins, and help disperse miasma. 16
- Its connection to the Earthly Dao allows Zhen Yuanzi to sense changes in the world's terrestrial origin, though it cannot pierce every obscured heavenly secret. 28
Restrictions and Formations
The book can manifest runes and restrictions as formations for sealing, refinement, and combat.
- Assisted Zhen Yuanzi in analyzing an Innate Restriction for ten thousand years until he opened a hidden Cave-Heaven. 8
- Generated a vast net of Dharma that trapped the escaping Lost Soul Bell. 9
- Formed arrays to suppress and refine Hun'e, drawing earthly qi from beneath the Nine Netherworlds to strengthen the killing formation. 11 12
- Combined with the Apricot-Yellow Banner and Nine Autumn Sword to imprison and destroy Hun'e. 13
- Its formation was broken when the unshackled Hun'e erupted with overwhelming force. 12
Defense, Sealing, and Capture
The Earth Book is principally a defensive treasure, but its restrictions also make it an effective tool of restraint.
- Its defense is considered comparable to only a few exceptional treasures, including the future Cloud of All Heavens and the Black-Yellow Pagoda. 6
- Captured a fleeing golden treasure after the opening of an Innate Restriction. 8
- Blocked Fire Luan's red rope and drew the weapon into Zhen Yuanzi's sleeve. 22
- Trapped Fire Luan in an Earth Book Formation after she attempted to flee. 23
- Collected Hun'e's scattered true-spirit fragments after his death to nurture them within the book. 13
Merit Storage
The Earth Book can store Heavenly Dao Merit for later use.
- Held Zhen Yuanzi's remaining Merit after the Lost Soul Bell was upgraded. 14
- Stored more than one hundred mu of Merit earned during the repair of earth veins alongside Heaven-Earth Daoist. 19
- Its stored Merit appeared as mysterious yellow qi and slightly strengthened its origin. 19
Opening the Pure Good Void Compassion Earth-Spirit Realm
Zhen Yuanzi used the Earth Book to establish and support his personal realm in the Void Sea.
- Expanded from ten zhang to roughly ten thousand li before becoming immeasurably vast within the Void Sea. 25
- Churned the void into Chaos and then separated that Chaos into heaven and earth. 26
- Created the Pure Good Void Compassion Earth-Spirit Realm, which received and concealed Zhen Yuanzi's Dao Fruit. 25 26
- Serves as the foundation of a realm that embodies Zhen Yuanzi's Earthly Dao and its future evolution. 26
Relationships
- Zhen Yuanzi — Accompanying spirit treasure. He possessed it before taking form, uses it as his foremost defensive and formation treasure, and has fully refined it. 2 19
- Earthly Dao — The book originated from the Heaven-Earth Fetal Membrane and is deeply connected to the Earth's veins, terrain, and terrestrial origin. 6 16 24
- Hun'e — The book repeatedly restrained and refined the Chaos Fiendgod; after Hun'e's destruction, it received his remaining true-spirit fragments for nourishment. 11 13
- Pure Good Void Compassion Earth-Spirit Realm — The Earth Book opened the realm in the Void Sea and became central to its establishment as the vessel of Zhen Yuanzi's Dao Fruit. 25 26
Trivia
- The Earth Book is stated to be only a thread away from becoming an Innate Supreme Treasure. 6
- Despite its exceptional defensive reputation, Zhen Yuanzi frequently employs it offensively through formations, seals, and earth-qi manipulation. 11 12 16
- The book's fully refined status distinguishes it from the Apricot-Yellow Banner, Pure Water Alms Bowl, and Lost Soul Bell, which had not yet all been fully linked to Zhen Yuanzi's fate. 19
