Thirteen eyed the God of the Apocalypse with a calm expression on his face.
On the other hand, Metatron was casually eating a fish cracker.
"You want some?" Metatron asked.
"No," Thirteen replied. "You already know why I'm here."
"No, I don't. How can I know if you don't tell me?"
"Hah..."
Thirteen heaved a deep sigh before glancing at the Rank 8 Goblin Emperor, who was looking back at him anxiously.
Originally, the Goblin Emperor thought that Thirteen was just a weakling he could casually kill without too much effort. Now he knew that reality was different.
Using his uncanny ability to read and predict his opponent's movements, the human boy was able to not only dodge the monster's attacks but also launch his own counterattack.
If not for the fact that Metatron came to stop Thirteen by dealing the final blow, the Goblin Emperor would have been dead by now.
Seeing that Metatron was playing coy, the teenage boy decided to get straight to the point and get it over with.
"Why did you stop me from killing that bastard?" Thirteen even pointed at the Goblin Emperor to ensure that the God of the Order of the Apocalypse couldn't pretend that he didn't know what he was talking about.
"That's because I pity you, Thirteen," Metatron replied.
"Pity me?" Thirteen frowned. "Why should you pity me?"
The teenage boy had thought of many reasons why Metatron had interfered with his battle, but pity wasn't one of them.
This was why he was genuinely confused with Metatron's answer. No matter how hard he thought about it, he couldn't think of any reason as to why he should be pitied.
The Goblin Emperor was an arrogant and proud monster. However, it could still reluctantly serve someone who had managed to defeat it despite the disparity in ranks.
"Since you want me to become strong and catch up to the other members of the Apocalypse, why not add them to the deal as well?" Thirteen pointed at Zed and Evuvug, who were on the other corner of the treasury.
"Hmm..." Metatron rubbed his chin as if to ponder this proposal.
As mentioned earlier, he didn't mind letting Thirteen form a strong army of monsters. But he felt like adding the Birdman and the Brain Beetle to the agreement was overkill.
Even so, as long as Thirteen was able to meet the conditions, he would allow him to have his way.
"Very well, I will agree to this condition,' Metatron stated. "So work hard, Thirteen. I look forward to you catching up with the rest of your peers."
After saying those words, Metatron disappeared.
Thirteen glanced at the Goblin Emperor, the Birdman, and the Brain Beetle one last time before he, too, disappeared from the Order of the Apocalypse.
Metatron's proposal was something he couldn't afford to pass up.
Having many strong monsters as his subordinates would allow him to push his plan forward several times.
Just having Evuvug with him would make him a force to reckon with. Adding Zed and the Goblin Emperor was merely a bonus that made the deal better.
When the teenage boy had finally left, Zed and Evuvug shared a knowing glance with each other.
They understood that it was truly possible for Thirteen to capture four more monsters. Once that happened, both of them would have no choice but to serve him as their Master.
"What do you think?" Zed asked. "Will he succeed?"
"Knowing him, unless he dies, this agreement is as good as done," Evuvug replied.
Zed was in agreement with the Brain Beetle.
Unless the teenage boy died in an attempt to capture strong monsters, this agreement between him and Metatron was already sealed in stone.
