A Sternhold combat squad rushes into a settlement to announce a Tier-4 Troll is heading this way and orders immediate evacuation. Xaden Lane, a transmigrator shunned by family and without a conventional Beast-Taming gift, reveals he awakened the Beast Supplier System and commands a division of spirit beasts. Officers scoff when his only visible guards are low-tier Blue Slimes and insist civilians leave. Xaden refuses to evacuate, saying his beasts will protect him, tells two slimes to warm up—one chirps—and a sudden cry rings out as the Troll closes in, the outcome unresolved.
After a roadside fight, a troll is killed in one hit by two Slimes. The captain and officers scan them with Bole Glasses and discover the Slimes are Tier-5 with an S-rank skill, Indestructible Body, and — impossibly for Slimes — unlimited growth. The team realizes slimes normally cap at Tier-3, so these beasts and their number could upend Sternhold if the news spreads. Tension rises as more infinite Slimes appear. Then a stranger approaches, murmuring, "I don't have much to offer, please forgive me." The group ends the episode asking, 'Just who is this man?'
A Sternhold Base special operations squad enters Xaden Lane's beast shop to buy Slimes. Xaden, a beast supplier, names the system's minimum: $3 million per infinite-growth Slime. The squad offers $6 million for two and, astonished by the rare creatures, says they'll report to headquarters. Xaden then reveals he has an unlimited, varied stock with different types and talents, so they purchase two and leave to fetch senior officers. The sale completes the system mission, and the system immediately awards a "new species," forcing Xaden to decide whether to open government channels.
In this episode, an auction offers a Tier-9 Kung Fu Panda and the Host spent $6 million of public funds to buy two Slimes. The Commander demands verification; Bole Glasses confirm they are God-tier Slimes with unlimited growth and S-rank talent. The System warns beasts can only serve inside the base unless more missions are completed. Scouts trace the Slimes to Xaden Lane, an exiled former young master. Initial reports of ten Slimes are corrected to 10,000. The episode ends as the Commander assembles the guard to visit Lane personally, preparing a confrontation.
At a city dump, former heir Xaden (Mr. Lane) is publicly taunted by Munira, who pressures him not to reveal their past and flaunts a new boyfriend. The Rose Guard, led by Commander Jennett Gore, unexpectedly arrives; Jennett treats Xaden politely and demands a private, important discussion, ordering civilians cleared. Munira amplifies her insults and others label him worthless, while observers are shocked by the Commander's courtesy toward someone in the dump. The episode ends with the crowd whispering, "How could he know the Commander?", leaving Xaden's connection to Jennett unresolved.
At a trading meeting, Mr. Lane reveals a horde of over 10,000 God-tier Slimes, shocking Commander Gore and Sternhold Base representatives. They haggle: Lane’s previous $3M per slime is raised to $10M to show sincerity. Sternhold produces $1 billion and asks to buy 100 now. Lane accepts; payment and a VIP card are exchanged. When asked about other spirit beasts, Lane hedges that he only has "a little." The meeting ends in stunned disbelief as someone gasps, "My god! How are there so many?", leaving the scope of Lane’s power unresolved.
A military delegation arrives at Mr. Lane's park after goblins explode from two to two thousand overnight, producing Tier-8 mutants—berserk, shaman and lightning types. Commander Gore orders the visit kept secret and his envoy Jennett completes a quiet transaction with Mr. Lane. Back at base the Host finishes a system mission by selling 100 slimes and unlocks Super Teleportation, a Beast Gift Pack and a Fast Kitty. The new function lets him summon an entire beast division anywhere, giving him confidence to leave base. But slimes were only the beginning, and the goblin surge looms.
At a high command meeting two years after he promised an elite force, Commander Gore faces accusations and a push to replace him with Jaeden Lane. Delegates deride the specimens as low-tier Slimes until Gore hands out Bole Glasses. Through the glasses the Slimes appear as near-divine beasts, shifting ridicule to stunned approval. Gore declares he will form a Blade Unit of these Slimes to defend Sternhold and offers one to Jaeden to experience personally. Jaeden accepts the Slime; the episode closes with him leaving to test it, the consequences unresolved.
A family meeting opens after a failed plot: unusual Slimes prevented forcing Jennett to resign. Jaeden reports there are no records of such Slimes in Sternhold or nearby cities. The group concludes producing a low-tier beast at this strength requires a Sage-level Beast Tamer, so the patriarch orders every family member to uncover the mysterious supplier. Meanwhile the patriarch gives the God-tier Slime to Xavion to contract with it; Xavion aims to pass the ninth rank. But Xaden, revealed still alive, is named as the intended sacrifice for the new divine pet, leaving him in immediate danger.
An emergency alert warns a lethal poison fog approaches the city as an outcast notes he can teleport and command beasts but lacks personal combat strength. A system side mission, True Foundation, appears: wash away humiliation and kill Xavion Lane; reward: true Beast-Taming talent and an exclusive growth-type contracted beast. Xavion arrives at the scavenger hideout, taunts the outcast for surviving after being hunted and insults his life as trash. He vows to send his divine pet to kill him. The episode ends with the mission offering power while Xavion's threat hangs, forcing an urgent choice.
