"Just wait, when the monster comes down to its last leg, I'll push it out and let you roast as much as you like," William finally responded back, while panting for breath.
He had his spirit power replenished all the time, but the mental stress was simply too much to handle. The monster was pressing hard on him, and a single fault would result in a bitter end.
William kept moving, and the monster chased relentlessly. After a while, he could feel the monster was starting to struggle. Its speed got lowered, and the spike attack frequency got diminished as well.
Less than ten minutes after feeling that, the monster moved all of sudden, heading out from William.
"It's running, roast it!" William roared, while chasing after that monster. He knew if he dared to go out of his formation range, then he'd suffer the monster's nasty ability again. So, he moved five of his monstrous weapons, the closest to the monster, to stop it. And yet the monster was adamant at getting away from William no matter what.
His monstrous weapons unleashed lots of attacks, and yet the monster dashed through them without stopping. The black cloud that already had few gaps showed more gaps, and few of these were so deep to show the deeper parts of it.
William and Fang were using their spirit sense to watch the monster, and the two could finally lay an eye over what this monster really looked like through these gaps.
It wasn't huge, the same as William read before in the old records. It was how the tales described it, three metres tall, with a body that didn't look that threatening.
There was little muscle bulk out there. "Is this the bastard causing all this trouble to us?" Fang couldn't help but ask William using telepathy, and the latter could only nod.
The moment William spotted such changes, and his heart sank in his chest. He didn't need to go out there and inspect the monster thoroughly to know what was going on.
"It's about to self-detonate, we need to hurry and take it down," Fang also recognised what was going to happen, "we can't risk losing the precious core and materials of this bastard."
"We can't afford to let it explode and bring down the entire place with it," William roared, realising this wasn't the time to play safe, "let's go, you keep hitting all the lightning over that mfer, and I'll keep hitting it with everything I got."
William hoped during this moment of losing control over its abilities, the monster's ability would be weakened or gone. Yet when he stepped outside the protection of his formation, he realised he was wrong.
"Dammit! Even when it's going to die, it's still keeping hold over its ability..." the moment William went outside of his formation, he felt his spirit power getting sucked like running water leaking. Yet he didn't stop this time.
There was no time to retreat, and let his monstrous weapons handle the situation. He took out tons of elixirs, emptied them into his mouth, while releasing tons of his attacks over the monster.
This time the monster didn't fight back. It was already remarkable to keep its ability active during all this. The attacks flooded the monster from William and Fang, and every passing minute felt like an entire lifetime.
The two knew how to handle this critical situation. A normal monster in the dark gold grade would explode to take down an entire area of thousands of metres. And this monster was special as it absorbed tons of spirit power already.
Letting it explode was like letting tens of dark gold monsters explode together. Fang eyed the loot of the monster, and William eyed the safety and integrity of the portal.
