He had gotten an idea for altering the Mana Bullet spell to create a new death-attribute spell.

Vandalieu had thought that death-attribute magic had limited ways to deal damage directly to enemies, but if there were limited ways, he just had to invent some.

He had postponed the invention of such a spell because he didn’t gain any experience from defeating enemies himself, but he could devote his efforts to it if necessary.

As a result, he had successfully finished developing a new spell yesterday. This spell was a projectile affected by the death-attribute with long range, high speed and a difficult-to-read trajectory.

“I’ll definitely win next time. There won’t be a seventh time,” Vandalieu declared confidently.

Unlike the regular monsters, mid-bosses and bosses that appear in Dungeons are produced by the Dungeon’s core.

That is why no matter how many times a boss is defeated, once a certain amount of time passes, a monster of equal strength appears in its place.


“Shaaah…”
“Shuaaa.”

Seven enormous snake heads large enough to swallow a cow whole were coiling around each other. However, there was only one tail.

It is one of the Dragon races, a serpent with multiple heads. When this creature hatches from its egg it has two heads and is the size of a Japanese rat snake, but the number of heads increases as it develops, as does the size of its body, the hardness of its scales, its regenerative abilities and the potency of its venom.

And once it matures to adulthood, it becomes an enormous seven-headed serpent known as a Hydra.

It is Rank 6, superior to Wyverns among the Dragon races.

Its intelligence is not much different from a normal snake and it is far less mobile than Wyverns.

However, its powerful body can mow down a human with ease, and it is difficult to wound it through its scales with normal methods. And the substance secreted from its fangs is a potent venom that cannot be removed without a special antidote.

And what makes this creature difficult to kill is its resilience that keeps it alive unless all of its heads are cut off and its heart is destroyed. If only one of these two steps are taken, its regenerative ability will allow it to make a full recovery in a matter of days.

Incidentally, Hydras can develop even further to grow an eighth head, becoming known as an Orochi. Its name was no doubt given to it by one of the champions from another world.

“I want a rematch,” said Vandalieu, seeing the Hydra that had appeared for his sixth attempt at fighting a mid-boss of Borkus’s Sub-Dragon Savannah.

“No, that’s probably impossible,” said Borkus, denying him immediately.

“But I just invented a new spell to deal with the Venom Wyvern’s mobility…”

The Hydra was less intelligent and less mobile than a normal Wyvern. Of course, it couldn’t even compare to the higher-Rank version, the Venom Wyvern.

“There’s nothing to be done about it,” Borkus told him. “It was actually really unusual that the same monster spawned five times in a row as the mid-boss in the first place.”
Normally, the race of mid-bosses and bosses that appear in Dungeons are not fixed. They tend to be of around the same general strength, but they are generated randomly by the Dungeon.

This Dungeon would generate Rank 6 Dragon or dinosaur-type mid-bosses.

The Venom Wyvern was probably one of the stronger monsters that could have been generated. The reason it had appeared five times in a row was due to Vandalieu’s bad luck.

“It’s not like that Hydra’s going to back down now,” said Borkus. “Try it out. That new spell of yours.”

“Sure… Death Bullet.”

As Vandalieu lifted a hand towards the Hydra that was raising its curved necks, a black object resembling shimmering hot air appeared at his palm.

He fired the Death Bullet at the Hydra that had sensed some extraordinary presence and was trying to escape.

The Death Bullet consisted of death-attribute Mana capable of draining an enemy’s life-force, condensed using the same principle as the Mana Bullet.

He couldn’t fire them consecutively because he still wasn’t used to casting the spell, but their range and speed were on another level. They also had a homing ability that allowed them to chase targets to a certain extent.

“SHIGYAAAAAH!”

However, the Death Bullet’s projectile speed and homing ability proved unnecessary as it hit the Hydra with ease. A scream rose from the Hydra as its Vitality was drained, and its heads began lowering towards the ground one by one.

Vandalieu fired multiple more Death Bullets, and once all of its heads were lying on the ground, he fired one last Death Bullet at its heart to deal the final blow.

What remained was the corpse of a Hydra that was dead despite being completely unwounded.

“Oh, that’s pretty amazing,” said Borkus.

“Considering that the amount of Mana I spent was equivalent to the entire Mana pools of a hundred first-rate Mages, not really,” said Vandalieu.
