The heavy infantry approached the first wall to gain entry into the kingdom. They at first baffled how they were wall built when records from 200 years ago had foretold the description of the walls and seeing the state of it made them rethink their plans.
From the records 200 years ago, the previous invasion of the Mirg Shield nations that was Sutter failure had told the destruction of the wall.
They couldn't wrap their head around it considering they only know that undead are mindless and couldn't be tamed due to their mind being twisted after death. Therefore they couldn't have the coordination to build it.
The ghouls that an brought wouldn't be able to build the wall that has the size of a titan wall. However, they quickly recomposed themselves and continued their invasion.
"Well it's about to start…"
Ryuu muttered standing at the middle wall using [ Byakugan ] to see the whole place having a ranging number of several thousands of soldiers. He turned to see the sun had started to set and even though it was still early, the sun was blocked by the tall mountain range.
He then focused his attention at the third wall where Van showed himself to the army, making every single one of them bewildered by his action.
He then brought out a spear which was Ice Age, a weapon made the strongest metal of Orichalcum, a magical metal of the gods, which is even harder than Adamantite and possesses greater anti-magic properties than Mythril. It boasts the greatest physical and magical defense of any material in the world.
It once housed a clone of the god of ice, Yupeon and the weapon wielded by a A class adventurer hero, Mikhail. The weapon was treated as the national treasure by the Mirg-Shield nations that was now snapped in half by Vandalieu.
Though it was obviously a fake one made of iron since breaking even molding a Orichalcum is only a mere dream. Van broke using the Golem transmutation skill that he had and At that moment, the entire stronghold fell silent for a moment before exploding with outrage.
"Damn you! How dare you do such a thing to our country's national treasure!"
"There is a limit to the insult we can endure! I swear on my honor as a knight that I will slay you!"
"You piece of shit! That Ice Age was supposed to become mine! You… You… I'll slaughter you!"
Riley swore, he was one of the group who hunted down Vandalieu's mother but had since left the part since Heinz, the leader of Five-Colored Blades had a change of view in life and left Amid Empire but still devotee of Alda faction, though a more friendly faction that was on the opposing empire of Amid Empire called Orbaume Empire.
Though, even if Heinz has a change of heart, he's a naive fool who tries to hide what he had done.
Every single soldier was livid from Vandalieu's action, taking a huge blow to their pride even when they realized it was fake. Soon the Van leaped into the second next Ryuu as the first wall collapsed close to the heavy infantry.
"It's funny how fast they become chaotic from your little show."
"I'm also surprised it's working quite well. Those books help a lot.*
"Are you going to follow the story?"
"Yes, for the most part but knowing the S class Thunderclap Schneider is my ally and not seeing him participate is reassuring."
At first the army tried recruiting Scheinder for the war but fortunately or unfortunately declined. It would be messy if he joined the war and ruined his reputation at the Amid Empire by acting as some sort of spy.
"Also, I'm still weak but I did acquire a mission on my own to defeat this army."
"Oh what's the reward?"
Ryuu thought that he was the only one who could complete the mission since Shinobu never acquired one.
"It's Gravity Magic."
He raised an eyebrow and wondered what it was. Ryuu slightly frustrated that his unable to use appraisal to see what the magic is like then it clicks on him.
'Well I'm stupid….I could use the shop to see it!'
Ryuu hadn't been using the shop because most items are extremely expensive and he only uses them to transfer skills. He then opens the store and check what the magic is like.
[ Gravity Magic ]
[ Description: Users are able to use a form of magic that is related and based on gravity. For example, one can use this magic to gain access to gravity-related abilities or gain the ability to use magic and cast spells using gravity or gravitational forces. ]
[ Cost: 70,000,000,000 ]
He wondered if the manipulation of gravity using magic includes velocity, inertia or even the magnetic field of an object. Ryuu could only imagine Van using it to easily crush his foe.
Putting their attention back to the war, Van soon used the Trebuchet to launch several stone golem that started slaughtering the army left and right. Though these golems were easily defeated, Van could easily revive them back and continue the fight.
"The disease seems to be quite effective."
Ryuu muttered, witnessing the soldier start coughing with the few exceptions where his "Evolved" infected. He evilly smiled seeing their suffering especially Gordon, The Vampire Hunter and the one involved in Van's Mother death.
At first they assume it was poison considering this is a clever tactic in war but unfortunately they have poison resistance to combat this. However, it was just their luck; it wasn't poison, but rather a disease.
"Shall we start hell?"
He smiled, jumping down the walls with two handguns made out of his flesh appearing like Alucard. Ryuu used [ Bone magic ] with [ Disease magic ] to make powerful bullets that are sure to kill.
As soon as Ryuu descended the ground quake and what ascended were Vandalieu's subordinates and his lover. He smirked, cocking the guns despite nodding to and began their slaughter.
"Everyone charges!!"
"Come forth, My shadows!"
"Greater protections! Greater Resistance!!"
Trese came out summoning her shadow army made out of rank 4 shadow raptors, rank 5 shadow TRI-horn, Rank 6 Venom Wyvern and Hydra and finally Rank 7 shadow brachiosaurus while Kie uses her magic to enchant everyone's abilities boosting everyone by several folds.
The darkness user swiftly despatches several soldiers with her Baruka daggers and the sinag, which was her personal dagger. She blended in the darkness and shadow that made it difficult for the soldier to see her in the midst of darkness.
The soldiers were too fatigued from disease that ate away their stamina and tried to push their limits by using the skill [ Surpass Limits ] but it was all futiles.
"KILL THEM AAAALL!"
"Protect the children! Slaughter the intruders!"
"Don't you dare set foot in our nation again!"
The morale of the Ghouls and Undead, who had been on standby underground for several hours, was high. None of them would have any problems with being in complete darkness, and more importantly, this was a battle to defend their home.
Upon seeing their arrival, some of the soldiers tried retreating but were mowed down by their enemies who had been strengthened by Kie. Though she couldn't always use her magic but still tried her best to help.
"Kaa-san, you should rest and leave the rest to us! Blue, let's go!"
"Roar!"
Nezuko came out riding her pet through the battlefield that started to demolish the troops using her near perfect flame control, burning those even with the thickest armor.
Perhaps they could have survived if they had Mythril armor but knowing the rarity of said metal was impossible.
"Bang! Bang! This is really fun!"
"....I feel like I became a horrible influence."
Ryuu murmured looking down, seeing Nezuko slaughtering the enemies with little resources and hesitation. He wonders if the [ Harem System ] helps their mind from being affected by it.
"I won't let you get away with this!"
One of the soldier screamed pushing himself heading towards Kie who was close using his sword technique skill towards her.
"I'm sorry but I can't let you do that!"
At that moment, Mitsuri, who was a few distant away from Kie, quickly used her sword whip that extended and grabbed the soldier before throwing him away. She executed [ Shundō ] accompanied by her breathing form that easily sliced through the soldier in half.
Thanks to the system's assistance, it became a lot easier for them to use magic and their techniques that they didn't think much about.
Furthermore most of their sword technique was at Level 10 that would become a superior skill once something triggered it to change.
"I feel sorry for these people but knowing their intention, the gods and the evil vampire behind them are to be blamed."
"We're lucky, Muzan didn't do something like that."
Kanae struggled and killed the soldier using petals that slice through them that were inspired by Byakuya's Bankai, slightly guilty at her action but didn't let it get to her knowing their intention and the outcome.
On the other hand, Shinobu was relieved that Muzan was too arrogant to manipulate humans and use them against the demon slayer corp. It would be troublesome for their corps to fight against their fellow humans.
"Yeah he's a dumbass!"
Leaping in the air, Justine came rushing through the battle with her gauntlet smashing even the toughest soldier and taking their attacks like nothing.
She was enjoying the thrilling battle beating everyone that she saw. Those watching thought her like a tyrant and covered in the blood of her enemies.
"I guess it's phase two huh? Show yourself my dear servant! It's time to feast!"
