Chapter 300 – A Demon King’s Book of Secrets

“Shion-san, what mischief are you scheming this time?” Kanon asks me.

“Mischief...that’s slander, you know?” I answer while diligently getting everything ready. “First off, Tomio...was it? I’ll give that guy a 『Big Black Iron Ax』.”

“Oohhh...a free gift from you? This is definitely going to have a catch.”Visit no(v)eLb(i)n.com for the best novel reading experience

“Just what kind of image do you have of me?”

“Demon King.”

“...Well, that’s what I am, no? Anyway, I’ll give him an ax and strengthen him...leading him to believe that there are treasures inside treasure chests.

“Treasures inside treasure chests...? Isn’t that only natural?”

“It is, but this is just to make sure. For the time being, I suppose I’ll take a look at Tomio’s situation.”

Once I check his progress on my smartphone, he’s advanced close to the location of the fake chest I had installed earlier.

“Hmm? Gii, gii, gii!”

As soon as he discovers the chest, he calls out to the goblins with him in Goblin, and they begin to cautiously surround the chest...then he slowly opens the lid with the tip of his crude sword.

“T-T-Thiiiis iiiisssss!”

Tomio holds up the ax he’s retrieved from the chest and begins to dance in joy with the goblins and kobolds around him.

Oohhh...he’s happy, so happy. And once you obtain a new weapon, you want to test it out, right?

Without losing a moment, I send newly created low-level goblins and slimes to defend, continuing to observe thereafter.

“Hmm? Fresh troops!? Gii! Gii!”

Once Tomio tells his goblins something, they step back, allowing Tomio to face the new arrivals with his new ax at the ready.

“Now’s the time for me to show you the result of my training!! Here I cooooooome!”

With rough nasal breathing, Tomio faces the goblins and slimes, starting to overwhelm them with his newly obtained weapon.

Oohhh, how strong, so strong. Even though he’s brain-damaged, he’s still a Demon King.

As I watch the excited Tomio...

“What are these 『Recommended☆』? Also, the descriptions of all races are slightly different from what I know.”

“As for the descriptions, I instructed Mrs. Tamura to write down while recalling what I had heard before, but...well, it’ll do. 『Recommended☆』 is something that Mastermind would use, don’t you think?”

“Ohh...given the 『Special Service☆』, it’s quite plausible. So, you’re going to give this to Tomio?”

“He’d be suspicious if he received it out of my hand, so I’ll give it to him by putting it into a treasure chest.”

“I see! In other words, you’re going to make him your subordinate after he becomes a Dragon Demon King, right?”

“It’d be great if all goes smoothly, but...I suppose that’s the aim here.”

All that’s left is to send in goblins or some such with serious killing intent. The ruler of this world ― the Mastermind ― doesn’t like backdoor tricks like exploiting holes in the system. If it’s subordinates I ordered to get defeated, it’s possible that it wouldn’t be counted.

“Well then, let’s believe all will go well and prepare the 『Demon King’s Book of Secrets』.”

I had the fake box with the 『Demon King’s Book of Secrets』 installed on the path Tomio would take during his invasion.
