That Time I Got Reincarnated as a Slime season 3 episode 4 highlights: Vesta and Kaijin's latest invention revealed

Picking up the events from the previous episode, That Time I Got Reincarnated as a Slime season 3 episode 4 opens with Rimuru Tempest asking his friends whether there have been any changes to the Jura Tempest's monster ecosystem.

Souei reveals that although a Sword Grizzly caused havoc in the forest, he took care of it. According to That Time I Reincarnated as a Slime season 3 episode 4, Sword Grizzly is similar to a Knight Spider, that is, equivalent to an A-minus rank.

Rimuru feels that the emerging monsters in the nation may become a problem. As such, Vesta suggests placing the Anti-Magic Barrier over the highways. When Rimuru enquires about it, Kaijin says that they have managed to build a fully automatic magic generator that can produce a barrier.

According to That Time I Got Reincarnated as a Slime season 3 episode 4, Vesta and Kaijin's Anti-Magic Barrier acts as a Rune magic. It automatically collects magicules from the air and utilizes it to create a barrier.

Considering the Monster nation has a high density of magicule, it's the perfect invention, as Rimuru feels. Besides that, Vesta reveals that they can use the device to activate different kinds of magic.

He also suggests installing the devices across the highways, which will activate the barrier. With immense magicule density in the air, there's no need to replace the device's fuel. All they have to do is to ensure the machine is working fine.

Diablo then explains to Rimuru that while he (Rimuru) can sustain his aura, for beings such as Veldora and Benimaru, it's important to let it out. The slime delves into a thought and tells Veldora that he will think about it later. Till then, he requests him to keep it in check.
