I'm a monster in Demon King's Castle

That was a gray-robed mage chanting an incantation. Each time his palm moved, a surge of magic would emanate, weakening the magic within the skeletons' soul anchors until it dissipated.

Clearly, it was some kind of purification magic targeting the skeleton race.

And there were about five such mages along Li Yue's route to the city wall—protected by clockwork soldiers, they not only didn't retreat but showed a sudden surge, gradually approaching the bone mages in the sea of skeletons, pushing back the bone sea.

“They are creating a lot of resistance for us…” Li Yue expanded his senses, standing on a broader perspective to analyze the entire battle situation.

“Okay, I'll kill him.” The words left by Yingying vanished in an instant, followed by her leaping onto the battlefield, like a sword constantly changing direction in another space, directly stabbing into the shadow of the gray-robed mage!

The gray-robed mage's throat tightened, and then his entire head twisted backward, unable to utter another incantation; the clockwork soldiers and soldiers around him also reacted immediately, their magic stones radiating holy light, dimming the shadows on the ground.

Yingying didn't look back, the wriggling shadows resembling a black hand from another space, deeply and lightly deforming, and then twisting the clockwork soldier who was releasing holy light into a pile of scrap metal.

“Okay, phew…” Yingying returned to Li Yue's side, and the advancing sea of skeletons also removed the gray-robed mage as an obstacle, continuing to surge forward.

Amazed by Yingying's mobility and the ever-changing attack methods of the demon expeditionary force, Li Yue understood that this was the different talent of different demons…

Hoping that his performance in this battle could leave some impression on Mento, so as to give some advice on "advancement studies"—Li Yue still kept in mind the purpose of the Blood River simulation battle, while understanding the battle methods of top demons and heroes, and continuously extending the destruction of the human garrison by the sea of skeletons.

However, Li Yue didn't follow the sea of skeletons straight ahead, but instead jumped left and right along the city's edge and wall slots, constantly correcting the routes that might be attacked, advancing in the sea of skeletons with a strange rhythm.

In this way, Li Yue and Yingying followed a relatively safe route, removing several gray-robed mages along the way while suffering only minor resistance, finally reaching the main city tower outside the city, about several dozen feet away.

On the other side of the city wall, demon wolf cavalry who had climbed onto the city tower had their sternums smashed by clockwork soldiers, and red-skinned demons and steam-powered soldiers entangled and fell off the city wall, smashing into minced meat…

But even with the battle so fierce, Li Yue still couldn't see any hope for the demon expeditionary force to break through the city.

And at this moment, the morning sun was just rising, and the light of day was about to tear through the darkness—by day, the demons' combat power would definitely be greatly reduced, no longer as ferocious as they were now.

The sea of skeletons also encountered a strong counter-attack force in front of the main city tower, and the battle line reached a strange balance—although according to this situation, the sea of skeletons would eventually engulf the main city tower, but that might be half a day, or even a day later.

And the sunlight had already caused some weakening to the demon expeditionary forces, whether it was the fire knives in the hands of the red-skinned demons or the sharp claws of the demon wolf warriors, they were far less powerful than at night.

On the city tower, the human commander and the great mage were fighting with Bosh and his group of guards, and their expressions still didn't change at all when they saw the surging sea of skeletons.

Bosh had shrunk a lot, currently only half of his original size; Kerry and Kerr were even worse than Bosh, having shrunk to almost a quarter of their original size.

The wing demons of the guard had already been completely wiped out, and the newly arrived wing demons along the city wall couldn't merge with the red-skinned demons, being torn apart and defeated by the spells attacking the sky before they could even get close.

In the city, there was also a sea of skeletons blooming in the cemetery, but it was quickly attacked and extinguished by the surrounding priests and soldiers, without causing too much of a stir.

Outside the city, the siege beast battle formation had basically been destroyed, and the remaining demon wolf cavalry and skeleton soldiers were resisting the heroes around the bell-shaped siege beast, but the thread maintaining the fragile balance could collapse at any time, leading to annihilation.

Immediately afterward, the changes in the world caught Li Yue off guard, and he stood there dumbfounded.

The sun that had just dawned only drew an arc in the sky before returning to the horizon, summoning a new moon…

The morning light bloomed and then suddenly disappeared, directly entering the second night!

As if being fast-forwarded a hundred times, the sea of skeletons on the city wall repeatedly bloomed, and then withered as it crashed against the main city tower wave after wave, in such a cycle… pushing the battle line straight under the city.

And at this moment, Li Yue noticed that the bell-shaped siege beast in the center of the battlefield finally landed on the ground, countless moonlight disk machines accumulated the previous night chased away the sun, covering all the demon expeditionary forces in front of the main city tower, forcibly accelerating their offensive pace, and also causing the current "accelerated" results!

The bell-shaped siege beast reversed day and night!

This is the battle of demons…

Li Yue suddenly felt a sense of powerlessness, sensing the "visible" passage of time around him, and for the first time realized that "war" could be forcibly accelerated in this way.

However, there was no corresponding description in the "history" given by Damon Benben…

Could it be because the three bone mages left in the siege beast battle formation helped the siege beasts resist the heroes' attack that was transmitted over, so the tactics of the bell-shaped siege beast could be brought into play?

Li Yue couldn't help but make such a guess, thinking that this might be the butterfly effect on the battlefield—perhaps the outcome of this battle is not as Damon Benben said, "You are doomed," but there is a possibility of victory?

From the moment Bosh gave the order for a full army charge to the moment the bell-shaped siege beast landed, the battle actually came to the moment when victory or defeat was about to be revealed at the end of the first night and the beginning of the new night.

Of course, this is based on Li Yue's judgment—the demon expeditionary army has no extra reserves, and there should only be a few demon sons left near the royal tent who have not participated in direct combat, such as the red-robed priest Redcoat, Damon Benben, Mai Mai, and Pigeo…

There are no expeditionary forces to command, what else can they do?

The acceleration in front of the city tower allowed Li Yue's sea of skeletons tactics to be maximized, causing great casualties to the garrison and clearing the way to the city tower…

Li Yue knew that next was the last chance to obtain battle merits—whether to win by breaking through the city or to have the battle situation reversed by the garrison's third great mage, there would be a result soon.

However, at this moment, the figure of the second great mage suddenly appeared next to the human commander.

White light flowed in the palm of the great mage, corresponding to a light array with an extremely wide coverage area in the inner city.

Was this to transport new reinforcements to eat up the remaining expeditionary forces attacking the city?

Then push all the way?

Li Yue thought that this battle was indeed as desperate as he had imagined before, but he still didn't give up looking for opportunities, preparing to drive the remains of Finley under his seat to avoid the front line for a while, and not to engage in a direct battle with the reinforcements at the first moment.

Holy white light enveloped the city tower, and figures began to emerge from the light and shadow; Li Yue barely resisted the erosion of the teleportation array with the self-healing bone, and called Yingying to hide in the shadow inside Finley's belly.

And it was after the great mage's teleportation technique was activated that a violent tremor came from the ground at the royal tent, and a sharp mountain peak rose from the royal tent against gravity!

The sharp stone pierced through the clouds, and then slightly changed direction, falling directly towards the main city tower of the Steel City!

“Redcoat! Hahaha! Well done—” When the sharp mountain peak was thrown into the clouds from the royal tent, Bosh, who had shrunk a lot, laughed loudly.

Bosh's guards also cheered and encouraged.

“Idiot, this is going to smash us to death too…” Li Yue looked at the mountain peak in the high sky that was gradually getting bigger and turning into a meteorite, unable to find any way to avoid it.

After that, Li Yue's rhythm was completely messed up—Bosh once again used the command authority of the expeditionary force to launch a charge order to all the demons on the city tower.

Losing the protection of Finley's remains, Li Yue once again became a skeleton head holding a bone sword under the main city tower, lonely, accompanied only by his shadow.

“This is my chance, goodbye!” Sensing the approaching and expanding shadow of the meteorite on the ground, Yingying suddenly jumped away from Li Yue, opening her arms to welcome it.

“Chance…” Li Yue sensed the great mage next to the human commander who was re-hooking his thumb, Bosh howling and approaching the main city tower in the sky, and the human reinforcements who were turning into entities beside him… suddenly felt that this might also be his last chance.

The last chance to obtain battle merits.
