I'm a monster in Demon King's Castle

The walls of the Demon King's castle instantly revealed countless gunports, covering the entire rampart—bone cannons.

As the city defense commander waved his hand, cannon fire poured down, showering the scorched earth encampment below.

The Demon King's City opened fire.

However, the cannon fire did not fall into the Empire's camp but was intercepted mid-air by the River of Fire unleashed by Qihe.

The crimson River of Fire burned through the bone bullets, prematurely detonating them, and a dense barrage of electricity, lava, firestorms, and ice shards surged before the Empire's army, becoming a barrier between the camp and the Demon King's City.

Occasionally, some bone bullets broke through the River of Fire, but they were scattered and unable to breach the knights' light shields.

The bone cannons and bone trees had led to the annihilation of the Empire's vanguard, so Qihe would certainly not allow his own army to be bombarded again.

"They came prepared..." Li Yue had foreseen this situation, which is why he put extra effort into developing the Satellite and the Hammer.

However, neither of those killing weapons had been successfully tested yet, so at this stage, he could only use endless cannon fire and manpower to slow down the war.

"Switch to ice bullets," Li Yue telepathically instructed Xin Xin, changing the ammunition for the bone cannons.

Clearly, that rampart should have become a meat grinder for the Empire's army, but instead, it was the other way around.

Aka also squeezed a drop of blood from his fingertip and rolled it towards the Colosseum.

"It's not for us to see," Li Yue waved his hand, "Up there... just pick a natural disaster!"

Dusk Earthworms were ready, the Staff of Deception was ready, and Door Door was also getting ready.

The sappers in the artillery formation seemed to have practiced this tactic long ago, quickly loading the cannons and then reversing the angle to fire from low to high.

Qihe pulled out the blue elements from his mage robe, switching to an Ice River, skillfully countering various elemental cannonballs.

So the firing angle of the bone cannons was also raised synchronously.

Wallace, representing the Holy Light Army, spoke, while the white-armored knights in the Scorched Earth Camp remained silent.

Looking at the silent Qihe and the Holy Light Army, it seemed that they were expecting a bloody rainbow.

But recalling the already dead, enormous head of the Demon Wolf King, the Forest Keeper felt distressed again.

"The Sword of Faith shatters all evil..." Even with the continuous sound of cannons, the angel's voice gradually became clear.

The Holy Light Army, like a giant sword, followed the maps drawn by the explorers, plunging straight into the Demon King's City and the Colosseum!

According to the demons' combat style, there should already be pure-blooded demons and skeletons charging up the rampart at this moment.

Only then did green shoots sprout on the Forest Keeper's face, calculating the consumption of his life force by the natural disaster, feeling somewhat reluctant.

"Then what if we send a section of the forest over there?" Li Yue considered the possibility of sending the forest beneath the Colosseum to the other side.

"They want to enter the Demon King's City... the opportunity has come, let's have a head-on clash." Guo Hua immediately thinned the density of the particles, intentionally leaving an opening for the Empire's army.

He marked the gaps in the bone wall, the maps drawn by the explorers, and the location of the Dusk Earthworms on the pages, offering advice to Qihe.

The premise is to slowly begin this boring test.

However, Qihe, the Holy Light Army, and the Brave's party still didn't make any moves, only exchanging fire with the Demon King's City, seemingly certain that the Demon King's City was the side that would take action first.

"Don't rush, you guys..." Cutting off the connection with the Mimic, Li Yue felt that the Empire's army wasn't waiting for the demons' charge, so they wouldn't easily fall into the trap.

"How long can they last? Anyway, we can keep playing like this—" The distorted eye in the high-altitude view showed a close-up of the bone bullets falling, stirring up the River of Fire.

"How about giving them a natural disaster?" Li Yue asked the Forest Keeper, "If we can take out their artillery formation, they definitely won't be able to resist charging up..."

But the next second, Qihe separated the earth element from his body and injected it into the Empire's magic cannon emplacements, suddenly raising the ground.

"They want to come in!" Dandan shook his particles.

"I heard the Colosseum is the knight's final destination?"

"This..." The Forest Keeper really didn't understand Li Yue's thought process, never even considering this question.

The Empire's army and the city defense forces exchanged fire, with the Ice River lying between the positions and the Demon King's City, constantly filtering the bone cannon's shells.

The Demon King's City was already ossified, and whether it was bone cannons or spikes, or even bone bullets thrown from the rampart, they could bring great disaster to the humans charging the city.

An opening leading directly to the Colosseum—if they wanted to lure humans into the city, they had to make them believe that this punch would hit the vital point.

The Empire's magic cannon emplacements began to rise, stacking to a height exceeding the Demon King's City.

Li Yue signaled the Forest Keeper to prepare.

"We have to give them a big one, otherwise they'll be too embarrassed to move their butts..." Li Yue chuckled.

When the Forest Keeper loaded a hundred-meter volume of Forbidden Forest into a demon chef's stomach pouch, and then stuffed the pouch into Door Door's brain groove, Li Yue only waited for the Empire's Brave's party to get ready.

"But we haven't purified the Forbidden Forest yet..." Long ago, the Forest Keeper and Guo Hua had discussed the possibility of triggering a natural disaster on the scorched earth, but under the influence of the Holy Light Army, they gradually stopped mentioning this tactic.

"Let me show you your final destination..."

At the same time, Guo Hua summoned the Dusk Earthworms from the distance of the Colosseum, gathering them above the bone wall.

"He heard what I said..." Qihe gave the order, "Advance."

"Hmm... they've grown taller..." Acheng was surprised.

The Holy Light Army stood beside them.

"Finally, it looks like a magic army is fighting..." Although the Empire's artillery fire was neither painful nor itchy to Li Yue, some shells accurately hit the Demon King's City's gunports, and began to cause losses to the bone cannons.

So he discovered it immediately.

The Empire's army began to retaliate.

"Is it feasible?" Li Yue asked.

Qihe didn't say anything, but the angel's voice fell into the war scholar's ears.

The Demon King's City was lower than the Scorched Earth Camp, and the firing angle range of the bone cannons was more flexible than that of the magic cannon emplacements. Firing from low to high was endless, and the ice bullets made Qihe's River of Fire increasingly thick, gradually dispersing.

But Dandan suddenly called out.

"Hmm... they can see us." Acheng always had a feeling of being spied on, and quickly reported back to Li Yue.

There were Dusk Earthworms, there was the Staff of Deception, there was Door Door... there were many options to choose from, and they could even directly bombard them.

"Feasible..." The Forest Keeper knew that Li Yue would do whatever he said, and immediately planned how large a forest to send over there to unleash a natural disaster.

But Guo Hua was already losing patience.

Li Yue also sensed it—Dandan's particles were Li Yue's sensors, and at this moment, many of Dandan's particles were mixed in the bone guns of the Demon King's City, preventing the Empire's army from intending to teleport.

Aka lifted his cloak, and the pure-blooded demons inside were eager to move; Galarick also held his flying dagger, ready to draw a bone shadow at any time, leading the skeleton army to charge the Scorched Earth Camp.

"This is a trap..." An Empire war scholar summarized the information, analyzing the battle situation.

Shadow, Dandan, Aka, Galarick, Acheng, Forest Keeper... even Lulu Feifei and the seven Brain Spirit Generals stood beside Guo Hua, waiting for Li Yue's next instructions.

As for the Holy Light Army, Qihe, and the Brave's party brought to the Scorched Earth Camp, they still hadn't moved, and the two sides were still probing.

"Over there." Li Yue's telescope was aimed at the hunters and explorers in the Brave's party, noticing that the hunters were using eagle eyes to search for weak points in the bone wall, while the explorers were drawing maps.

Then, Li Yue called Galarick to follow his skeletons fully armed, and together with Legis's leg hairs, to gather at the Colosseum.
