The cultist however commits suicide after being captured; leaving behind a magical lantern he used to control the monsters. Yuji passes out from using too much magic.

Yuji continues tracking the rock dragon with Tina and Lisa. The moon and sky suddenly turn blue, as foretold by the cultist’s prophecy, and a blue dragon appears, forcing them to shelter in nearby Delight Canyon. The rock dragon emerges and blocks Yuji, Tina and Lisa from going further. With the slimes Yuji uses a powerful fire spell to burn the Earth Dragon so only its skeleton remains. With the dragon skull and the bounty on Gelios the guild pays them 14 million gold. Yuji is drawn into a meeting with Guild Chief Rayard and Grand Cathedral representative Father Steyl. Steyl reveals in church legend the dragon appeared and destroyed a continent before being defeated by a divine emissary who rivalled the power of God. 30 years ago the church performed a summoning ceremony to cause the emissary to appear one week before the dragon, but the emissary never came. Even without the emissary Rayard orders the guild to attack the dragon at first light. In private, Steyl reveals a holy vision directed him to gift Yuji a church relic, the Dagger of Kethis, which can focus magic power. At night, as his slimes report the blue dragon continues to grow larger, Yuji fears many adventurers will die and comes to a decision.
Yuji and his slimes spring an attack on the dragon. Utilizing protective barrier magic Yuji is able to avoid the dragon’s attacks, and with his fire magic concentrated in the Dagger of Kethis, stabs it in the neck so the explosion kills the dragon instantly. With the dragon mysteriously defeated Steyl leaves but Rayard suspects Yuji. Having drawn too much attention again Yuji leaves for the town of Ricaardo which, according to Tina and Lisa, is a completely ordinary place. Dryad informs Yuji dead dragons contain something called Dragon Grace, which has sprouted mushrooms around the corpse with which she can make potions, red to increase Sage skills, and Blue to restore depleted magic. As the potions brew Yuji remembers first meeting Dryad dying after an unidentified person drained her forests magic with a crystal, so he saved her with a magic transfusion then destroyed the crystal, restoring her forest. Yuji encounters a village shrouded in fog called the Village of Messias. The villagers are suspicious of his presence but allow him to leave when he assures them he was just lost. As he leaves the villagers contact an unknown person to reassure him their plan to retrieve the Dragon Grace is unaffected. Yuji makes it to where Ricaardo should be but finds the landscape covered in unnatural snow.
Entering Ricaardo Yuuji learns the snow is unusual and the villagers were unprepared for it, since their firewood has already been used up. Disappointed he can’t try Ricaardo’s famous cuisine without cooking fires, Yuuji figures out how to use his slimes to dry out freshly chopped trees to make perfect firewood. The town chef, grateful for the wood, cooks Yuuji one of his finest dishes in gratitude. Seeing the rest of Ricaardo is still short on wood, Yuuji joins the local foresters and shocks them by procuring enough wood for the entire town to last several weeks. Yuuji receives yet another meal, but the chef reveals it is not his best food as the fields where the town grows its famous herbs is plagued by monsters eating them. Proudwolf and the slimes help locate the boar-type monsters and defeat them. They also find a crystal orb which turns out to be Dragon Grace refined into a cursed crystal is absorbing all the magic in the area and causing the snow. Following other crystals set in a circular pattern, Yuuji locates the pattern’s center and, despite Dryad’s unhappy permission, destroys the forest around the center, revealing an old house with a trapdoor leading underground.

Yuuji discovers an enormous machine using stolen magic absorbed by the crystal orbs to produce Dragon Grace. The slimes explore the cave and emerge in Messias, proving all the villagers are Blue Moon cultists. Their leader Javier is furious Yuuji’s destroying the forest also damaged the machine. Working in secret the slimes swallow all the cults sacred texts and treasure. Yuuji decides to kill the cultists, until Javier mentions a weapon called Cleansing Flame, which will destroy the area if the cultists die, including Ricaardo village. Yuuji decides to let them live, but all the cultists abruptly commit suicide to activate the Flame. Working quickly Yuuji retrieves the slimes and, combining every magical barrier he knows, creates a new spell called Total Isolation Barrier prevents the Flame spreading beyond Messias. The snow starts to melt and the Ricaardo villagers celebrate Yuuji as the Firewood Hero and reward him with Chef’s true finest meal, since he now has access to his herb field again. The texts are booby-trapped with a spell turn them blank, except for a list of the cults targets, which includes Yuuji. Elsewhere, two assassins with an identical list choose Yuuji as their next target.

On the advice of the villagers Yuuji heads for Boginia, a town famous for outfitting tamed monsters with armour. The assassins follow him to determine if he is a threat to the cult. Aware of their presence, Yuuji considers killing them but worries this will draw the cult’s attention, but instead he decides to find a way to have his name removed from the assassins list. Reaching Boginia, Yuuji puts on a convincing act he is a penniless idiotic drunk. He also attempts to pretend to be an amateur monster tamer while batting several Bull monsters, but his warrior instincts are too strong and he accidentally reveals his skill with a sword. The assassins are confused but eventually conclude he is a complete novice with some natural sword skills, and leave to report to their employer who reveals to them about Messias destruction. The slimes overhear the assassins discuss their next target, Father Steyl. Unwilling to let Father Steyl get killed, Yuuji has his slime set off an ice explosion, freezing the assassins solid. With the assassins dealt with Yuuji is able to act normally again and asks Boinia’s best armorer, Geigel, for armour for his slimes. Geigel agrees but claims there is a problem with a monster at a nearby volcano.

Geigel reveals to craft suitable armour he must have a jewel from a Blue Lesser Fire Dragon. The volcano is a nest for Lesser Fire dragons, and Blue are the rarest. Yuuji learns from the guild the only way to defeat one would be to fatally cool their bodies with water from the closest available river, which is home to a giant monster piranha. On the way Yuuji tames several red fire slimes who help him capture the piranha for a large bounty. He also defeats multiple dragons using water summoned by magic and collects their jewels. His slimes eventually locate a blue dragon which is defeated by ice magic. Returning to the guild Yuuji collects multiple quest rewards for killing 202 dragons, 2 blue dragons and the piranha. With an abundance of jewels Geigel crafts armour for the slimes and Proudwolf vastly increases their speed, though he warns Yuuji his most powerful spells could damage or even destroy the armor if overused. The only way to craft stronger armor is with a jewel from a true Flame Dragon, which lives in the lava of the volcano and rarely comes to the surface. The remaining Lesser dragons suddenly go mad from the same cultist spell which made 10,000 monsters attack Phastan, and the Flame Dragon itself emerges from the volcano.

The slimes spot two men heading for the fire dragon carrying barrels. They mention they came from a town called Ordarion. They avoid Yuuji’s trap, proving they are experienced, but they are captured regardless. To avoid interrogation they commit suicide, proving they were with the cult. Dryad confirms the barrels contain cursed water, a weaker version of the cursed crystals, probably designed to enrage the Flame Dragon. It begins to rain, which enrages the Fire Dragon who never emerges during the rainy season in case the rain extinguishes its fire. Terrified, the villagers evacuate Boginia while Yuuji stays behind to confront it. The dragon is so hot its presence dries up a river. Yuuji uses ice magic to slow the Dragon down while using a barrier to dam the river, releasing the collected water once it rises high enough and completely submerges the giant Dragon. This only enrages it and it attempts to destroy Boginia. Yuuji is forced to use his strongest ice spell and freezes the Dragon solid, killing it. The slimes collect the dropped Flame jewel and also discover an object near the volcano. Yuuji gives the Flame jewel to Geigel who promises to craft armour never seen before. Yuuji discovers the object is an artificial rain maker, meaning the cult made it rain to enrage the dragon on purpose.

Walter places himself inside a machine infuses his body with Dragon Grace, mutating him into a dragon. Yuuji outfits Proud Wolf and a slime with their armour, allowing them to destroy part of Walter’s body. Walter absorbs Grace from his monsters, healing himself and growing larger. Coordinating his slimes, Yuuji traps Walter in nets and destroys his body. Before dying Walter prays the Revelation will begin. Walter’s machine activates upon Walter’s death, absorbing his corpse, his monsters, and even Johann, to summon a one-eyed man who calls himself Sage. Steyl is forced to reveal the rest of the Revelation to Yuuji, the death of a teacher shall cause the Emissary to be victorious. He had assumed it would be his death made Yuuji victorious, but it is clear it actually meant Walter’s death would resurrect the original emissary that died centuries ago fighting the original blue dragon. Sage, using magic similar to Yuuji’s, attempts to kill him and destroys the cave to escape into the sky. Despite a ferocious fight Yuuji and his slimes are unable to defeat Sage. Sage begins the Salvation of the world by activating multiple rain maker machines powered by Grace, creating rainclouds to rain Grace over all the land, infecting monsters across the world.

The monsters begin attacking nearby villages. Sage claims he will provide Salvation by destroying the world. The slimes reveal in every village he has visited adventurers and citizens have risen up in defense of their homes, inspired by Yuuji. Steyl receives a new revelation; when the sun and moon unite divine judgement will be bestowed. Sage demands to know why Yuuji insists on defending the world, and Yuuji only responds he happens to like the world as it is. Using his most powerful spell called Divine Judgement, Yuuji concentrates the spell into the Dagger of Kethis, causing a light so bright it temporarily eclipses the sun, just as in Steyl’s revelation. Sage is stabbed with the dagger and destroyed. Despite every village celebrating, Yuuji once again chooses to quietly disappear. Elsewhere, the remaining cult members dismiss Walter's death as trivial as they are working on a new machine, The Purifier, which will destroy the entire continent and with it their final enemy, the Black Dragon of Judgement. Eavesdropping via his slime Yuuji is exasperated the cult still hasn’t given up. After collecting another bounty in a new village Yuuji learns from local guild leader Meggia defeating dragons and Sage has made him famous across the continent and his desire to live in obscurity is now impossible.
