The next day, the sky was just beginning to lighten with the first hint of dawn.
"Miss Zhou, once the battle begins, you can stay in this position."
This is the Rest Gate within my formation, possessing extremely strong defensive capabilities. As long as the formation remains intact, you will not encounter any danger. Since your abilities can be activated from a distance, this place should be very suitable for you.
I hope you will try not to leave this position, otherwise it may interfere with the operation of the entire formation, do you understand?
The attack on the demon castle ahead was about to begin, and Chen Mu specifically asked Zhou Xinle for a few words of advice.
The Heart Devil Fox's ability to control souls is terrifying. If it can fully assist Chen Mu, it will be of great help in dealing with the Demon Lord.
However, Chen Mu did not fully trust her yet, so he only used her as an assistant.
"No problem!"
Zhou Xinle nodded, her big eyes darting around, seemingly lost in thought.
After everything was prepared, Chen Mu took to the air, his hand seals changing as he adjusted the placement of the red crystals below, transforming the concealment formation into a powerful, lethal one.
After a while, the sky had fully brightened, and Chen Mu had finished adjusting the formation, so he began the formal attack.
Da da da...!
The runes on the twenty siege cannons lit up simultaneously, and then energy shells emitting an eerie red glow were launched into the air, flying towards the distant demon castle.
Demons are not creatures that work at sunrise and rest at sunset; their state at night is similar to that during the day, while the early morning is actually their more relaxed time.
Boom!
With a series of earth-shattering explosions, the Demon Castle was instantly thrown into chaos, leaving it in ruins.
"Again!"
Without pausing, Chen Mu continued to control the twenty siege cannons below, launching the next round of bombardment.
Due to limited resources, the mechanism Chen Mu created to launch the cannonballs was very simple. The only standout feature was the siege cannonballs, which used the Devil Spirit Cannon technology that Chen Mu had been researching.
To create the Devil Spirit Cannon, the most important things are demonic energy and Spiritual Power. The red crystal inside the demon contains demonic energy, while the Spiritual Qi can be provided by Chen Mu, Mingye, and Zhou Xinle.
It was precisely because of the Devil Spirit Cannon that Chen Mu was so confident in taking down the demon castle before him.
Chen Mu had studied the Devil Spirit Cannon for over twenty years, and it was arguably the wide-area killing technique he was most familiar with. Each cannonball fired by these siege cannons was no less powerful than Sage's full-force strike. With so many Sage attacking at the same time, even the Demon Castle, guarded by a Demon Leader, was thrown into chaos for a time.
Whoosh whoosh whoosh...!
Chen Mu seized the opportunity and launched four rounds of artillery fire in succession. By the time the fifth round of artillery fire was fired, a large force finally organized inside the Demon Castle and swarmed towards Chen Mu's location.
"Roar~~!"
Suddenly, an incredibly terrifying howl emanated from within the Demon Castle. Although Chen Mu and Mingye were still several miles away from the Demon Castle, the sound still made their ears ring.
" Half-God Level expert, truly terrifying!"
Chen Mu was secretly alarmed, but not too worried, because he had calculated that the demon lord would not leave the castle easily.
In the Destruction Grotto-Heaven, neighboring demon castles frequently wage war against each other, but the demon lords rarely leave their castles, for the secret of demon birth lies within: a mysterious pool flowing with lava.
The lava pool is crucial to the demon lord, serving as his primary source of power, so he will not easily leave the castle unless absolutely necessary.
"Come out, everyone! The war has begun!"
Chen Mu waved his hand, and Shi Xing led the Specter Legion out, forming a battle formation and standing ready for battle.
The ten Heavenly Stems War Soldiers also drew their weapons from behind, and their metal joints began to move, their appearance gradually becoming fierce and imposing, indicating that they had transformed from their normal form into their combat form.
Then Chen Mu formed hand seals, and giants, each over ten feet tall, appeared out of thin air. A total of one hundred and eight of them rushed out, letting out fierce roars into the sky.
"Kill!"
Tens of thousands of demons charged towards the direction of the Demon Castle, but Chen Mu remained fearless, commanding the Heavenly Stems War Soldiers, the Specter Legion, and the Dharma Aspect True Body to block their path and confront the demons head-on.
Boom... Clang clang clang!
Chen Mu had carefully chosen his location; it was on higher ground, and the non-flying demons would expend a lot of energy just to rush up there.
The road up the mountain was also quite narrow, which weakened the numerical advantage of the demons. Under Chen Mu's careful planning, the charging demon army could not gain any advantage at all.
"Ugh..."
The demon army was led by more than a dozen Saint Level demons. Their intelligence was far superior to that of ordinary demons. They even knew how to use tactical maneuvers to lead a portion of the demons up the mountain and charge towards the location of the siege cannons from another direction.
"Ms. Zhou, we might need your help with these matters."
In single combat, Chen Mu's strength was only slightly stronger than that of an ordinary Saint Level Peak, but in group battles, the three groups he unleashed were battlefield reapers. The Specter Legion killed thousands of demons in just a few charges.
So strong!
Zhou Xinle was completely impressed by Chen Mu's endless stream of methods. She couldn't understand why Chen Mu was able to release so many powerful beings. Was it just because he was a talisman master?
"No problem, I'll handle these escapees!"
Zhou Xinle dared not be negligent. He immediately changed his hand seals, and strands of silk flew out from his body to attack the demons climbing up from the foot of the mountain.
Pfft...!
The weaker demons, unable to resist, were quickly and completely controlled, then turned around and attacked their own companions.
Whoosh...! Clang... Clang!
Mingye wasn't idle either. She suddenly appeared behind a Saint Level demon, brandishing a gray dagger. In just a few moves, she pierced the demon's heart.
This sneak attack was premeditated, which is why she was able to defeat her opponent so quickly. Afterwards, when faced with the siege of more than a dozen demons, she could only temporarily avoid their attacks and escape the encirclement using her agility.
Rat-a-tat... Boom boom boom!
Under Chen Mu's control, the twenty siege cannons continued to fire. After more than a dozen rounds of bombardment by Devil Spirit Bullet, there was hardly any intact part of the Demon Castle. Only in the very center of the Demon Castle did a tall building still stand firm.
