Planetary Space

Biodata

History

The ancestors of ancient Xia discovered Planetary Space during an age of mass extinction caused by the emergence of secret realms and their beasts. Its discovery helped usher in the age of ninja and the establishment of the Nine Provinces Alliance 1.

Unlike other inheritance-bearing realms, Planetary Space contains no Demon Beasts. This makes it an unusually accessible source of powers that otherwise require dangerous expeditions: other realms containing King inheritances may be controlled by Level Seven King Beasts 1 5.

Entrances and Administration

• Distribution: Entrances exist throughout the Nine Provinces. The realm does not appear to form one continuous space, yet entrants can quickly reach the Inheritance Tower regardless of their entrance 11 14.
• Planetary Space Fifth Town: The entrance used by Qi Yuan lies in a town built around the gateway, more than fifty kilometers from Shangcheng No. 1 Middle School. It receives students from several nearby cities 11 28.
• Gateway: The entrance appears as a rotating sky-blue vortex. At Fifth Town, it is concealed behind a black screen in a meeting room before opening to students 12.
• Guardians: The Alliance assigns Level Five Grandmaster experts to protect entrances during the annual opening, despite the absence of beasts inside. Jia Nan and Liu Tianjun guard the entrance at Fifth Town 12 23.
• Post-inheritance assessment: Students remain in town for a Martial Trial after the realm closes. Qi Yuan’s cohort takes its trial in a separate, newly discovered D-Rank Secret Realm—not inside Planetary Space 12 13 30.

Entry Rules and Hazards

Detection Chips

• Every student receives a Detection Chip that merges into their flesh and records events during the visit. The chips detach after departure 13.
• Recordings provide evidence against students who attack fellow entrants. In Yu Province, attempted murder inside Planetary Space carries a sentence starting at thirty years; Lin Tao is also threatened with losing his gains and being reduced to a commoner 23 24.
• Qi Yuan’s chip stops recording after he enters the eighth floor. Staff suggest that the floor’s unusually high affinity requirements may interfere with the device, but this explanation is not confirmed 22.

Internal Dangers

• Unqualified ascent: A boy surnamed Yu dies when his body explodes after attempting to force his way into the middle floors 15.
• Mental-energy attacks: Weakening someone’s mental energy can lower their effective chakra affinity below 50, causing the realm to deem them unqualified. Zhou Hua dies after using a mental-restraint scroll in an attempted attack on Qi Yuan 13 14.
• Dangerous inheritances: The absence of beasts does not make every reward safe. Sharingan inheritances can cause severe bodily harm, and earlier recorded eighth-floor entrants died soon after their visits 4 23.

Inheritance Tower

• Exterior: An enormous golden pagoda, pale gold at its base and progressively darker toward the top 13 14.
• Navigation: Internal locations have no fixed map; entrants must search for routes between floors 14.
• Access: Chakra affinity determines which floors an entrant can reach 4.

The successful values of 321 and 521 demonstrate access, but the exact minimum requirements for the eighth and ninth floors are not established 18 19.

Inheritances

Selection and Rewards

• Inheritance offers appear randomly; stronger inheritances are less likely to appear. Entrants can refuse available offers and continue searching 4 14 15.
• On the lower floors, offers appear as transparent energy masses with text identifying the reward. They follow their intended recipient until accepted or left behind by ascending 14.
• Chakra inheritances have levels one through three, with higher levels granting larger chakra infusions. Qualified entrants can obtain at least a chakra inheritance if they avoid fatal risks 14.
• Kekkei genkai inheritances can grant both an immediate chakra increase and knowledge of their use. Lin Tao’s Boil Release raises him from provisional ninja to early Level Three and imprints the necessary hand seals in his mind 16.

King Inheritances

• The seventh floor contains fifteen documented King inheritances. Named examples include Kakashi Hatake, Might Guy, Jiraiya, Orochimaru, Tsunade, Shimura Danzō, Hiruzen Sarutobi, Hatake Sakumo, and Tobirama Senju 5.
• Xu Ying receives three options: Kakashi, Hatake Sakumo, and Tsunade. She favors Tsunade for medical ninjutsu, vitality, chakra control, and compatibility with her existing Ice Release 17.
• All fifteen King inheritances select Qi Yuan as a potential recipient, but he continues upward rather than accepting one 18.

Sharingan and Wood Release

• Sharingan: One-, two-, and three-tomoe inheritances can appear on any floor, unlike other kekkei genkai. They are considered undesirable because of illness, poor chakra growth, and increasingly severe bodily damage 4.
• Higher Sharingan legacies: The eighth floor contains Mangekyō Sharingan-bearing figures. Three initially appear; the remaining three emerge after Qi Yuan raises his affinity to 521 18 19.
• Wood Release: Tenzo’s Level Six Expert inheritance is identified as its only source. Despite its lower rank, it is described as many times rarer than a King inheritance, with no known recipient in recent decades. Wood Release can alleviate Sharingan side effects 29.
