I'm a monster in Demon King's Castle

Having taken a trip to the colosseum, Li Read naturally reaped a harvest of malice. Now, he could go all out and properly strengthen the library.

As long as he kept Budhibug from leaving the bone chamber reception room from now on, Abada's javelins would only concentrate in that same area; until Budhibug died, or Abada died.

The Killing Sea Butterflies that Li Read had originally left outside the bone chamber reception room were already enough to last for a while. If he infused some high-density iron essence, it would provide Budhibug with better protection.

Simultaneously, it was also time to improve the library's sturdiness.

However, Li Read's magic power was currently exhausted. He had only just received the library's replenishment, so he couldn't start work immediately. It would be best to rest and recover his energy, and then turn the plans in his head into reality.

Right, and the safe zone—Li Read invoked the library's authority and searched every corner of the library from head to toe, discovering that except for the Thirteenth Archive, there were no blind spots in the other locations, so he was temporarily relieved.

As for exploring the Thirteenth Archive, Li Read hadn't scheduled it yet, waiting for the library to start developing again before dealing with it.

Returning to the upper cavern of the library, Mini and Mini, along with the Brain Spirits, tactfully didn't come to disturb him. Li Read looked at the empty bath and the lonely Soul Altar, and lowered his head to glance at his shadow.

Nothing had changed.

Li Read continued to release iron essence—after turning Egg's particles into sensors, these particles were scattered to various key nodes in the library. Originally, Li Read planned to connect the library into a whole with bone, and if necessary, even complete an overall transfer to avoid certain crises.

… …

"Aren't there two prisoners! Take them down!" Oogiboogie bounced back to the ground, beckoning the Fly Demons to drag two people over.

"He, my magic cocoon is still throwing, throwing, throwing, throwing his magic cocoon's mud butt!" Oogiboogie knocked off the mud under the low platform, and Abada smacked onto the edge of the low platform, hurriedly wriggling back.

The library's development was back on track, only Budhibug was still constantly escaping in the bone chamber reception room, as if it had become the only meaning of his demon life.

Brain Spirits, Slave Scholars, Mini and Mini... When they reassembled in the library hall, everything in the library hadn't changed, yet it seemed to have changed.

If in the future... the library could detach from Demon King City, fly into the sky, and then be filled with magic cannons...

Colosseum, the dust raised hadn't settled yet, and the King of the Colosseum had already returned.

Still that lineup, still flipping through books?

"Hehe..." The strong man smiled.

《Lethal Mechanisms》, 《Complete Book of Practical Agricultural Tools》, 《15 Ways to Cook Syntis Snails》 and other books related to life and facilities were listed by Li Read as the first priority for the Brain Spirits and Mini and Mini to learn; the remaining 《Basic Magic》, 《Code of Conduct for Holy Knights》, 《White Forest Beast Clan Trade Interests》, 《General History of the Chaos Continent》, etc., were "interest-based" reading materials, for the demons to consult on their own, find their own unique paths, and find what they were passionate about.

Originally, in 《Lethal Mechanisms》, there were many mechanisms that required power to be made.

A red fly flew out of the bag and landed on the gunman's cerebellum, starting to gnaw.
