I'm a monster in Demon King's Castle

Li Yue, in the Thunder Pool, had finally managed to swallow the first Thunder Core. The surrounding electricity had also weakened somewhat. Li Yue had no energy to observe the situation outside the Thunder Pool, and naturally didn't know that the Chieftain had arrived.

The burning of the electric current and the "self-healing" that Li Yue had forcibly imposed on his tentacles had reached a bizarre balance, and Li Yue still maintained his ability to move.

Recovering from the paralysis and slightly stabilizing his condition, Li Yue struck while the iron was hot, rushing towards the next broken rock—the Thunder Core was completely isolated after being placed in the stomach pouch, as stable as eating a piece of cake. But Li Yue was still uneasy, and even forcibly applied "self-healing" to the stomach pouch to eliminate unstable factors as much as possible, preparing to devour all seven in one go.

To eat the Thunder Pool.

"What's going on!" the Chieftain shouted outside the Thunder Pool.

"You're back..." The guard found it difficult to explain what was happening inside the Thunder Pool, only saying that a vagrant wanted to become a guard, so he was undergoing the Thunder Pool trial.

"Then why is a corner missing from the Thunder Pool?" The Chieftain stared at the empty space in the Thunder Pool, and at Li Yue, who was being drawn towards other electric fields. "Where's our electricity?"

"It seems... to have been eaten by him..." One of the guards had sharper eyes and saw Li Yue swallowing the Thunder Core.

"Eaten? Eaten by such a cripple?" The Chieftain noticed the stiffness in Li Yue's movements in the Thunder Pool, and couldn't understand why this Evil-Horned Beast hadn't been electrocuted to death.

"He... mutated..." The old Evil-Horned Beast said cautiously.

But there was a way, now they could only use their mouths.

But it was very slow. The eight electric lights disappeared almost completely, and only eight lumps remained on the Thunder Core's abdomen—the guards' blood and electricity were sucked clean by the octopus tentacles and the Magic Wolf's Fangs, and even their flesh and blood were mixed into the patchwork of the monster. Their bones remained.

"They retreat! I'll drive it out!" The Chieftain could no longer remain calm. Lightning flashed from his mane, urging the eight Evil-Horned Beast guards to enter the arena.

Those eight guards were naturally the best in the tribe, able to withstand the Thunder Pool for about seven minutes. Hearing the Chieftain's order, they dared not hesitate, and simultaneously leaped into the chaotic Thunder Pool.

Before the lightning disappeared, the world seemed to be dark for an instant. And when the Chieftain regained his sight, he saw that in the place where the Thunder Pool had been, a tentacle monster covered in electric blue light was constantly wriggling, collapsing and twitching, rolling and stirring its body, until a plain white horn arched out.

Electrocution plus impact was already the Evil-Horned Beast guards' greatest effort; but at this time, the Thunder Core was stiff, unable to dodge, and eight lightning bolts pierced its abdomen.

The old Evil-Horned Beast who brought the Thunder Core was now unable to think, wondering how he had only picked up a vagrant, and now he had eaten his home?

It was this Evil-Horned Beast vagrant's white horn, also the low-level material that Thunder Core had instructed Minnie and Minny to buy in the Demon Market—before the white horn protruded, Niu Ju's horse-like face also stretched out from the rolling tentacles, eyes, ears, and mouth flowing with electric light, seemingly trying desperately to digest the thunder and lightning he had just swallowed.

"Explode! Explode!" The Chieftain, seeing the vagrant lose consciousness, roared the desire in his heart, hoping that the Thunder Pool could burst its stomach pouch, so that light could be rebuilt in the Forbidden Forest.

"I want to eat more!" As the Chieftain roared, the stiff Thunder Core had already smashed the seventh broken rock with a headbutt, and in a flash of lightning and thunder, sucked up the seventh Li Yue with a slurp.

"What kind of mutation is this? Has it become bigger and dumber?" The Chieftain looked at the huge, stiff Thunder Horse, feeling that his position was threatened.

Eaten it.

With a snap, the Evil-Horned Beast Chieftain was electrocuted into a pile of charred meat.

"What exactly does he want to do—" The Chieftain, of course, could see that Niu Ju was getting smaller, issuing a roar that instantly resounded through the Forbidden Forest.

Having eaten this much, even if the Li Yue brought back can't be used, the hundreds of electrified tentacles accumulated by the Thunder Core are still enough for the library to use. Now, instead of feeling uneasy like before, he has time to quietly admire the main body of the Thunder Pool, which has lost the protection of the broken rocks.

"Ram it!" The Chieftain also realized that the battle situation was not optimistic, and ordered the eight guards to launch a physical attack—after a moment of stunned silence, the eighth Niu Ju was eaten by the Thunder Core, and the size of the Thunder Pool was about to shrink to half.

Even though they were imposing, they were still extinguished in the electric light of the Thunder Pool itself, except for making the Thunder Core stiff for a moment, without causing any impact.

And just as the electric light was about to completely burst through the tentacles and the vagrant's body, the Evil-Horned Beast's eyeballs burst, but suddenly gathered all the electricity in its body onto the white horn.

Helpless, the Thunder Core could only become larger, then open its mouth.

And the Thunder Core had no time to pay attention to the Chieftain's roar. In the stiffness of the muscles, it sensed that the Thunder Pool, which had lost the other Li Yue, was on the verge of collapse. A slight carelessness would trigger a thunderstorm in the Forbidden Forest.

Electricity 77%.

Niu Ju stretched the patchwork of the monster to the maximum. At this moment, he couldn't care about continuing to maintain the form of the Evil-Horned Beast, but instead transformed into a river of tentacles, rolling and surging towards the Li Yue in the center of the Thunder Pool, and used his will to open the stomach pouch.

The electric light instantly converged, replaced by a series of non-stop explosions in the air, and the surging of magic power after the explosions—in the Forbidden Forest, a Thunder Pool where the Evil-Horned Beasts had lived for generations was gone.

These eight guards also didn't hold back any longer, releasing electric currents from the giant horns on their heads,猛击 the Thunder Core; but the Thunder Core was already receiving the Thunder Pool's baptism, so how could it care about these few extra electric arcs?

And at the same time, the lightning pierced the air, folded a few cracks, and struck the Evil-Horned Beast Chieftain at the edge of the huge cave.

Thunder Pool bagged, and the Demon Illustrated Handbook in my mind also popped up a prompt.

And the Thunder Core didn't care about the few giant horns that suddenly appeared in the Thunder Pool. There was only a piece of light and electricity in its eyes—smash it, eat it...

Just one shock almost filled all the octopus tentacles inside the Thunder Core's body, and almost split the bones.

The old Evil-Horned Beast and his companions huddled underground, shivering.

And the moment the stomach pouch opened, the electric light became a bridge between the Thunder Pool and the stomach pouch, drawing an incomparably thick electric arc, as if opening a huge thunder gate in the empty space of the Thunder Pool, then suddenly shrinking, merging, and closing.

The eight guards had no choice but to immediately wrap themselves in electric light, turning into eight lightning bolts, striking the Thunder Core's lower abdomen!

"Delicious." The Thunder Core finally leaped out of the empty cave in the form of a giant Thunder Horse, and then stood up on the disciple at the edge of the cave, tentacles extending from his stomach, patting his belly.

In a flash of lightning, the white horn bloomed with thunderous light, and then completely shattered.

The huge ball of light flickered, seeming to have some connection with the Li Yue inside the stomach pouch. Lightning split the air and probed towards the Thunder Core, making Niu Ju stiff again.

The electric light intensified, and in the rolling tentacles, the Evil-Horned Beast's head swayed slightly, and layers of lightning-like blood vessels appeared on the blue-white skin, seeing that it was about to be burned by the electric current.

And the Thunder Core also quickly devoured the surrounding Niu Ju, trying to wake up from the stiffness and twitching, quietly watching the most dazzling ball of light in the center of the Thunder Pool.

"Kill it!" The Chieftain roared, and eight electric lights also moved around in the giant Thunder Horse's abdomen, seeming to be about to break out of its belly.
