The most important thing was that he didn't need to find monsters with certain weaknesses to do it. He could affect any monsters using his arrows. And even if the monsters were at much higher grade than him, at a level that was quite threatening for the masters in this world, he could still make them turn against each other.
And that was the brilliant thing about this weapon.
*Fwoosh!* *Fwoosh!* *Fwoosh!*
He managed to affect thousands of monsters in one spot, but many more were hunting him down. As he needed to buy himself time, he took out his flying weapons, and let them hack the bodies of the nearby leopards.
William was sure that his flying weapons needed lots of rounds of attacks to take just tens of these monsters. In that time, many more monsters would appear and surround him. So he didn't remain in his place for even one second and kept releasing more arrows at other places.
The toxin he produced and impeded in these arrows was enough to remain in the air for ten minutes at least. And with the dense number of arrows released at one spot, it was expected to last more.
He started to slowly retreat while spreading his arrows around. He didn't stop there and kept alternating toxic arrows with the explosive ones, greatly affecting the movement of the leopards forward to get him.
He knew he was just lucky this far thanks to the scarce number of monsters in this region. He was at the outer border of the growing number of monsters coming out from the portal. And that told him things would turn south for him and others the moment this army started to seriously move towards the city.
So William focused more at scattering lots of his toxic arrows at many spots, aiming to create stress points that could help in alleviating lots of pressure later on. After all, the toxin would affect any monsters sniffing it. Eventually monsters would turn against each other, expanding the area of clashes among them, while more monsters would replace the fallen ones.
The only downside of this was the short time available for his toxin to work. Ten minutes or even tens of minutes were nothing in the long-term war that was coming soon. Not to mention he was just one person, unable to handle everything alone.
"I want you to gather all the alchemists and artisans in the city…" once he realised his serious this situation was, he decided to lend the formula of making this berserk type arrows to Lara. he estimated that they got no more than a day before the tsunami of leopards would hit the city.
So, it was better for the city to unify their efforts and start mass producing this toxin. As he was facing such a grand monster tide, and his toxin needed a large amount to work, he decided to not limit the toxin in the form of arrows.
Instead, he thought about filling barrels with the toxin, planting them in the area surrounding the city for tens of kilometres. In addition to that, he thought about using a war weapon he already prepared during the past five years, the catapult!
It wasn't a very effective weapon in normal conditions. But when faced with such an army of monsters, and when he needed to release tons of toxin barrels from far away, this weapon came as a brilliant solution.
[So… You want me to take all the artisans and alchemists, make them stop producing potions, elixirs, and weapons to make this weird thing?] Lara was surprised when she heard what William wanted her to do.
"This isn't just a normal thing, it's the weapon that will change the tide of this war," William rolled his eyes, shifted around using his technique, escaping the tight circle of leopards that just surrounded him, "make sure to take this matter quite seriously. And make sure no one will try and test or release this substance in the city. Or else, we will lose, and everyone will die."
[Got it! Leave this matter to me… By the way, did you get any useful intel about this monster tide?]
"Just expect the worst, that's all I can say for now," William paused for a second there, considering telling her about the truth of this monster tide.
Yet he refrained from doing so. He knew this was going to end up with one result: panic!
Instead of causing a great problem now, he decided to let masters experience how deadly these leopards were when they'd arrive at the city.
"I have to keep them busy here as long as possible," William took a swift look at the piece covering up his chest. He planned to use his recently made weapon back at the battle to defend the city. Yet as other intentions he got before facing these leopards, he knew he had to use this weapon now.
"You brought monsters that don't belong to this world here, and it's time for me to match your move with another, using a weapon that doesn't belong to this world…" William's gaze turned all serious, scratched his skin with his sword, before covering the entire chest piece with his blood.
Then a miracle started to happen next.
The first thing to happen was for this piece to issue lots of cracking and clicking noises. Then it broke free from his chest, expanding fast, growing in size, like a dried-up sponge that contacted water.
The small chest piece started to grow fast, with more pieces expanding and appearing from within it. William kept flashing around, protecting this place from any monster drawing near.
*Clang!*
The chest piece transformed and changed into such a behemoth standing by his side. He looked at it in pride, with its shining black, red, and golden outer layer that gave it a very intimidating vibe.
"Time to activate you," William grinned with excitement. He took a deep breath, and then stirred up his spirit power.
