Premise

In the future, as humans continue to advance their technologies, a sudden catastrophic geological change arrives, leaving the Earth's surface in ruins. Decades later, Mana Ecosystem, a biological network of monstrous, mutated creatures, takes over the land. Earth is believed to be unsurvivable. A group of people who were on a giant flying fort survived the disaster. They named the fort — Lighthouse. However, survival on Lighthouse depends on strict social hierarchy and regulation. Citizens are divided into upper and lower levels based on their genetic quality, and order is maintained through three core doctrines: gene optimization, collective education, and elder expedition.

Setting

Lighthouse (introduced in S1)

In the Old World, Lighthouse was originally called Tartarus. It was an aerial prison over the North Pole. It held felons, individuals powerful enough to escape law, secret agents, and researchers in mind areas. After escaping the geological catastrophe on the ground, the first Lighthouse Master eased the conflict between guards and prisoners. Tartarus was renovated into Lighthouse, meaning the hope for humanity's future. Initially, Lighthouse unconditionally took in survivors from the ground. After the invasion by surface forces in Lighthouse Year 5, Lighthouse shifted to a conditional rescue policy. In Year 11, Lighthouse confirmed the ground surface was not suitable for human survival.
After years of development and facing the crisis of resource shortage, Lighthouse issued the Three Core Doctrines: gene optimization, collective education, and elder expedition. Citizens are divided into upper and lower levels based on their genetic quality. The upper citizens hold key social roles, while the lower ones perform tedious manual labor in exchange for limited resources.

The Hunters

Specialized unit in charge of gathering resources from the Earth's surface. The team is equipped with heavy firepower and Heavy-Duty Mechas to fight the Extremozoans.

Light and Shadow Society

Religious institution on Lighthouse. It worships The Lord of Light and Shadow. In charge of enforcing the Three Core Doctrines and punishing those who violate the regulations. The doctrine of the church is: ''"Light breeds all living, all living follow shadow. Light cleans my soul, shadow shields my body. Using ethics to suppress desire, joy but not dissipated. Rather to give up my body, but to follow light and shadow."''

Lighthouse Defense Force

The military and security body in charge of maintaining order and operational stability within Lighthouse.

Ecology Research Institute

Research organization studying Mana Ecosystem and its biological mechanisms.

Laborer

Residents who fail to meet the genetic-quality standard. Perform labor work and live in the hanging lower levels of Lighthouse known as the Pigeon Cage.

LongGu Village (introduced in S2)

A place founded and led by Bai Yuekui, housing hundreds of people. The village accepts ground survivors and does not control villagers' emotions. Here, people can form families. The eligible couples who pass the parental test are permitted to reproduce. The villagers train to manipulate their inner Life Substance, transform it into power that one can control. There are three steps to reach Substance Potential: generate intent-force, compress Life Substance, and initiate potential power. Those who activate Life Substance power are called Awakeners. Through practice, the villagers can hide their presence from Extremozoans by entering the Guiyuan mode. The village uses Shielded Towers to keep the Extremozoans away. The towers have frequency filters to capture the special magnetic field released by an unknown source and use plasma emitters to magnify the field.

Mana Ecosystem (introduced in S1)

After the catastrophic geological change, a new ecosystem, Mana, emerged. Extremozoans surfaced from beneath the Earth's crust. Mana produces Scarlet Pheromone that will cause hallucinations in humans and threaten human lives. The Extremozoans in Mana subtract Life Substance from humans and then deliver gathered Life Substance to Mana Flora, which will then deliver the substances to the entire ecosystem, driving Mana evolution. It is said that the key to defeating Mana lies at its center, where only Mana creatures can enter. The Extremozoans can generate energy through photosynthesis.

Production

Ling Cage was developed initially by a 150-people team. Pre-production — including scriptwriting, art design, storyboarding, and asset development — lasted a year and a half, with official production beginning in November 2018. The story focuses on "humanity" as the core to the story, delivering hope in desperation. The team chose 3D production for its ability to handle long action sequence with complex camera movement. The central creative concept of Ling Cage is: courage nourishes hope.The project contains the ideal of community of common destiny, eastern philosophy, and apocalyptic ethics. It draws inspiration from Chinese culture including meridian, traditional martial arts, and Taoism. The setting of "Life Substance" in the animation as the combination of information, energy, and data. To ensure technical accuracy, the production team 3D-printed models of items such as heavy-duty mecha and vehicles to support animation workflow.
The animation technique of Ling Cage elevated in Season 2 and the team experimented various storytelling techniques such adding more music-action sequence to the show and playing with different editing styles. The show is selected as “2024–2025 NRTA ‘Outstanding Online Audiovisual Works Creation & Promotion Project.’”
For Season 3, the production team visited science labs such as Huairou Science City, Institute of Vertebrate Paleontology and Paleoanthropology to invite scientific consultant for topics such as Brain-Computer Interface and further solidifying the setting of Extremozoans and Mana Ecosystem.
