Background / History
The wild Black Tortoises lived in an underground lake and coexisted symbiotically with an Ancient Vine. Their seventy-thousand-year elder rested on a central stone island. After Su Chen’s group killed the vine, they used its scent to draw the herd away from the island, but the elder advanced toward Su Chen instead of taking the escape route prepared for it 25.
The elder’s shell resisted the group’s attacks, and its Netherworld Water Domain turned the lake into a lethal battlefield. Su Chen discovered that releasing the domain exposed core scales beneath its shell for less than three seconds. His companions exploited that opening to crack its defenses; when Su Chen touched the breach, the tortoise recognized the authority of his Supreme Summoner martial soul and submitted. His fourth Spirit Ring then produced ten Black Tortoise summons 26 27.
Appearance
The wild elder resembled a small black mountain. Its mineral-encrusted shell measured more than eight zhang across, and its eyes were cloudy white 25 26.
- Summoned tortoises — Heavy, dark shells marked with ancient patterns; defensive light spreads from their shells 27.
- Later hundred-thousand-year summons — More than twenty-six feet long, with profound-ice patterns on their shells 147.
Abilities & Skills
Ancient Black Tortoise’s defenses
- Its shell reduced Iron Wall’s Sky-Rending Claw to a shallow scratch and resisted the Shadow Leopards’ claws 26.
- Its ordinary forward movement broke the bears’ Dark Golden Iron Wall formation on the lakebed 26.
- Vulnerability: When it released its domain, abdominal core scales opened for less than three seconds. Coordinated mental, fire, ice, and physical attacks exploited that gap 26 27.
Netherworld Water Domain
- The elder transformed the underground lake into black water that consumed life force and suppressed other abilities; it spread death energy through air and earth when the elder came ashore 26 27.
- Yan Wuji’s Profound Ice Forbidden Domain could not freeze the transformed water 26.
Black Tortoise Immortal Shield
- Summoned tortoises link their shells into a shield wall or dome. Ten used the formation to withstand Niu Gao’s Rhino God Charge without a crack; their Legion Aura increased their attributes by fifty percent 101.
- The shield can repair damage: cracks caused by the Blood Nether Python’s bite closed within three seconds 63.
- Larger linked formations protected Su Chen’s group from a beast tide and, later, a catastrophic shock wave. The latter defense held, but three tortoises were critically injured 118 147.
Nether Exchange
- Allows Su Chen to exchange positions with a Black Tortoise, moving either himself or a tortoise into the path of an attack 48 63 124.
Defensive sacrifice
- Su Chen can sacrifice Black Tortoise summons to reinforce his own body. Five seventy-thousand-year tortoises gave him carapace-like defensive patterns that withstood the physical damage of Nether Lightning Douluo’s attacks 130.
Relationships
- Su Chen — Summoner and commander of the defensive legion. He thanked wounded Black Tortoises before recalling them after they shielded his group from a shock wave 27 147.
- Ancient Vine — The wild herd coexisted with it; its death left the tortoises highly stressed 25.
- Iron Wall — Accepted the newly summoned tortoises alongside the Fearclaw Bears on the legion’s front line 27.
