Chapter 1: Defending the Great Wall (1)

"... So they're finally asleep"

He said with a soft and kind smile on his face as he tucked a little girl with long silky golden hair and emerald eyes like her mother, to bed. 

"... I'm sorry that daddy isn't able to stay with you for the past few months"

He said as he kissed her on her cheeks, causing the child to relax and smile while falling into deep sleep.

"... I'll definitely protect you all"

He said with a serious expression on his face as he took a glance at the dozens of children that was sleeping on his bed. 

Even though he was there when they grew up, he still felt a bit guilty for leaving them alone for a few months, and even years because of the worsening situation of the frontline. To the point that even their mothers, who took care of them everyday had to be sent to the battlefield to control the situation.

"Goodnight"

He said as he shut off the light of his bedroom and slowly closed the large door without creating any noise. To avoid waking them up from their sleep.

"Lucias?"

A familiar voice said, causing Lucias to turn his head to look at the source of the voice.

"Mavis? You're still awake?"

Lucias asked with a slightly surprised expression on his face.

"Did you forget that we don't need sleep? It's been 1 month since we last saw each other"

Mavis said with slightly pouted cheeks, causing Lucias to chuckle before walking towards her direction.

"Sorry... the situation is becoming more hectic than I imagined"

He said as he wrapped his arms around her waist, causing her to smile as she responded by wrapping her own arms around his neck.

"I understand... but you should visit them more often. Don't you know how lonely they felt for not seeing you?"

Mavis said as she stole a glance towards the bedroom.

"Sorry"

"No need to apologize"

She said as she gave him a soft kiss on his lips, causing Lucias to close his eyes before his hand slowly tightened around her body.

"Lucias... Do you want to come to my bedroom?"

She said close to his ears, causing to look at her in surprise since she was not really the type to take the initiative in this kinds of things.

"Can I?"

Lucias asked causing Mavis' cheeks to slightly blush before giving softly nodding her head in response.

Lucias, seeing her nod her head, gently carried her petite body in his arms before walking towards Mavis' bedroom located at the 3rd floor of the palace.

"Lucias?"

A soft and beautiful voice asked before Lucias could enter Mavis' bedroom, causing him to look at the opposite room where both Pandora and Bell were currently at. Looking at him in surprise since they didn't expect for him to be back home.

"Hmm..."

Pandora hummed as she alternatively looked at both Lucias and Mavis with an understanding expression on her face. Bell on the otherhand immediately blushed as she could guess what they were planning on doing.

"Aren't you going to go in?"

She asked with a slight smile on her face. As the space around them to distort, before all 4 of them appeared inside of them bedroom.

"It's been a while since we last bonded, haven't we Lucias?"

Pandora said before pushing Lucias on the bed, causing him to sit down while Mavis flew towards his side.

"Avoid getting us pregnant, alright? It will be hard if all 3 of us suddenly dissapeared from the battlefield afterall"

Pandora said as she kneeled down in front of Lucias, before unzipping his slacks. Mavis and Bell followed suit as they kneeled together beside Pandora who pulled his underwear down. 

"Hmm..."

She hummed as she stared at his large shaft with a lustful expression on her face. Holding it with her soft, warm hands before stroking it up and down. 

Bell then immediately moved her closer to the base of his shaft before beginning to lick it with her small tongue. Making his shaft twitch as Pandora suddenly opened her mouth and swallowed his entire head.

"Mm..."

Pandora moaned as she started to lick the tip of his shaft from inside her mouth. Wrapping her warm tongue on his head while both Mavis and Bell started to lick the base of his shaft.

Lucias who felt their tongues wrap around his shaft, grunted in response as he gently placed his hand on top of Pandora's head.

The room was instantly filled with wet slurping noises. Pandora then started to bob her on his shaft, causing her saliva to drip down from between her lips. Completely drenching his shaft with her saliva while both Bell and Mavis didn't mind and continued their actions.

"That's it"

Lucias muttered before Pandora removed his shaft of her mouth. Bell then started to lick the head of his shaft as Pandora suddenly took the other side snd forcefully kissed her with Lucias' shaft in between their mouths.

"Mnnm"

Bell moaned as they both started to take off each other's clothes, revealing both of their petite bodies, and smooth porcelain skin.

Mavis on the otherhand, stopped her actions before climbing on top of the bed. Giving Lucias a deep kiss on his lips as she started to strip his clothes off. Revealing his mascular body.

"Lucias..."

Mavis dazedly called as she kneeled beside Lucias with her simple white nightdress.

He then lowered his head down to her small breast. Licking the soft pinkish tip of her breast before he playfully bit it with his teeth.

"Mn!"

Mavis moaned as she wrapped her arms around his head before Lucias slowly inserted his finger on her slightly moist entrance.

"Nmmm!!!"

Pandora loudly moaned as Lucias released his white liquid in her mouth. Catching her by surprise.

"Warn me... next time... Lucias"

Pandora complained before pulling Bell close to her lips. Kissing her fiercely as Pandora pushed some of Lucias' semen inside her mouth, causing Bell to unconsciously swallow the white liquid. All while both of them exchanged both saliva and semen with each other.

"I'll go first"

Mavis said with a dazed expression on her face as she positioned herself on top of his lap. Aiming the head of his shaft towards her warm, and moist entrance.

"I love you, Lucias"

Timeskip

"Lucias-sama, welcome back!"

His elite soldiers shouted as they all saluted as soon as Lucias entered the extremely large hollow part of their airship.

"You arrived quite late, Lucias"

Sephie said with a light grin on her face, causing Lucias to awkwardly smile in response.

"It looks like you had a lot of fun last night, Lucias-sama"

She said. Since she was at her daughter's bedroom that night. So, they to heard the 3 girl's moans that echoed throughout the quarters of the harem. 

"*Cough* I don't know what you're talking about, Sephie"

He said, causing Sephie to grin before letting him off the hook. 

"So, are all the units that I requested here?"

Lucias asked as he stoop on a slightly elevated floor, looking at the 1,000,000 strong units that were all standing firmly in their place.

"200,000 sorceress, 100,000 angels, 400,000 arcane gunners, and 300,000 trolls. They're all here, Lucias-sama"

She reported with a serious expression on her face, unlike the teasing look that she had a moment ago.

"How about my fiancée's armies? Are they all prepared?"

He said, causing Sephie to nod her head in response. Even though he said his fiancées armies. Only a few of them are actually assigned a role of an officer to deal the army like Lucifer, Azazel, and Artoria who were all experienced in leading a large scale army by themselves.

They were just there to provide support since most of his fiancée were all powerful in their own rights. So they're aid will be a tremendous help to the army stationed at most countries.

"They have been all prepared, Lucias-sama. All armies are already prepared to launch a full scale attack to take over the dimensional rifts"

Sephie said causing Lucias to smile in response.

"But are we fine with just this little numbers, Lucias-sama?"

She said with a slightly worried expression on her face. Since the location that Lucias picked is one of the largest hotspots of dimensional rift around the world. Only ranking 3rd with both Russia and USA, taking the 2nd and 1st spot respectively.

"No, but most of our troops are at the borders. They should arrive here if we manage to hold on for 4 hours"

Lucias said as the airship that they were on opened its hatch. Creating a small bridge to the Great Wall of China as the sound of explosion and loud shrieks of the Gastreas devoured their entire surroundings.

"Hold your ground!!! Reinforcements are here!!!"

A human shouted as Lucias immediately descended on the wall. With the thousands of soldiers following suit while the airship moved across the wall to spread their forces out.

"Cast any destructive spells to the back of the opposing army!!"

Lucias shouted as he amplified his voice using mana. Spreading across the entire battlefield.

"HAI!!"

All of the sorceress shouted as they all created a massive magic circle beneath them.

"Trolls!!! Don't let any Gastrea set foot on the wall!!! Protect the sorceress at all cost!!"

He ordered as the 4 meter foot humanoid trolls all raised their large shields and swords in response.

"Arcane gunners!! Focus on the Gastreas close to the walls!!"

He ordered causing all of the arcane gunners that he bought to position themselves close to wall. Reading their guns as they quickly injected their mana within it.

The Gastreas on the ground shrieked loudly as soon as they heard Lucias' voice. Making all of them to act insane as they quickly charged at the walls. Climbing it as quickly as they can without any regards to their lives.

"Gunners!! Ignore the Gastreas climbing the walls!! Trolls!! Keep them from getting close"

Lucias shouted as the mark on right hand shone.

"[Restia]"

He said causing a jet black blade to appear within his hand. Releasing an ominous demonic aura.

[It's been a while since you've used me, Lucias]

[How about me?]

Est said in a sulky voice from within his mind, causing Lucias to chuckle in response.

"I'll use you later, but what I need right now is Restia"

He said as he watched the Tier I and II Gastreas quickly climb the edge of the wall.

"[Flame Enhancement]"

He said causing his sword to blaze into flames. The Gastreas who arrived at the top of the wall quickly charged towards his direction.

The Gastrea quickly jumped at Lucias with a fierce look on it's face. Lucias then swung his sword upwards, creating a massive curved wave of flames and launching it towards the Gastrea. Slicing it in half while killing all Gastreas behind it.

"FIGHT TO THE DEATH!!!!"

The original soldiers stationed at the walls shouted as they quickly grabbed their swords and charged towards the Gastreas who managed to climb the wall.

"ARGHHHH!!!"

A soldier shouted as he stabbed a Tier I gastrea on the head, before slicing his blade upwards. Killing the spider type Gastrea who jumped at him from above.

"KILL THEM ALL!!"

They all shouted as they began to clash with the Gastreas.

"[Explosion]!"

The sorceress all casted, creating thousands of massive magic circle up in the air before thousands of explosion erupted from the enemies side.

"ARGH-"

One of the trolls shouted but was cut off as a sticky like flesh attached to his back and pulled him out of the wall. 

"CHARGE!! CONQUER THE WALLS EVEN IF IT COST YOU YOUR LIFE!!!"

The demon that came out of the dimensional rift shouted as several new Tier IV gastreas came out of the dimensional rift. Standing at a feet of 20 meters tall with hundreds of thin, long, fleshy tongue coming out of its mouth. 

"W-What is that?"

One of the soldiers said before he watched their tongues extended rapidly. Charging at the walls at full speed.

"No... TROLLS HOLD YOUR SHIELDS UP!!! SURRENDER IT WHEN THEIR TONGUE GETS ATTACHED TO IT!!"

Lucias shouted but was too late as the tongues attached on the soldier's bodies before pulling them towards the Gastrea at full speed.

"AGHH!!!!!"

One of the soldier shouted before getting pulled into the Gastrea's mouth. The Gastrea then proceeded to close it mouth and chew on the soldier's body.

"FUCKING INSECTS!!"

One of the soldier shouted as he activated the core hidden inside his body before getting pulled inside of the Gastreas mouth.

"MEN!! PREPARE TO KILL YOURSELF!!"

"HAI!!"

The trolls that were captured by the tongue, shouted as they all begun to activate [Self-destruction] before getting devoured by the Gastreas.

Large explosion then occured within the Gastreas mouth, blowing their heads to smithereens before their lifeless bodies fell on the ground.

One by one, the soldiers were kept getting captured by the Tier IV Gastrea, causing Lucias to grit his teeth in response.

"Restia!!"

He shouted causing the sword in his hand to transform into a bow. Injecting his mana into the bow as he pulled the bowstring backwards. Aiming it at the Gastreas at the back of the army.

"[Destructive Enhancement]"

He said as the mana arrow begun to expand. Creating a massive arrow of spiraling mana in his hand.

"Focus and don't panic!!! Focus on your stations and don't let them bombard us with their numbers!!"

He shouted aimed the arrow at the sky. Predicting it's trajectory before he released the string of the bow.

"[Rain of Arrows]"

He said, causing the arrows to split into thousands of pieces before raining down at the hundreds of Tier IV Gastreas at the back.

The arrows then all pierced a large hole on all of the Gastreas and Demons at the back of the army. Killing several tier IV and below Gastreas as thousands of small explosion of mana erupted at the back of the army.

"PREPARE TO FIRE!!"

The noble demon at the opposing army shouted, causing all Tier V Gastreas to open their mouths as a small ball of mana started to condense in their mouth.

"FIRE!!"

He shouted, causing powerful beams of mana to fire on the walls.

"[AEGIS]"

The angels shouted as they all respectively blocked a beam of mana aimed at the walls.

"Summon the golems!!"

One of the soldiers from the human army shouted, causing all of the Alchemist at the other side of the wall to conjure several magic circles on the ground. 

The hard soil then begun to rise up from the ground, creating a 3 meter tall giant covered with armor of stone.

"DEFEND THE WALLS!!"

The soldier shouted as the Golems all begun to climb the walls from inside the city.

"This human-"

The demon wanted to curse but was shot dead by an arrow that pierced a large hole on his head.

"Annoying piece of shit"

Lucias cursed as he prepared another mana arrow to take care of the Tier V Gastreas laying at the back of the army.

"[Destructive Enhancement]"

He muttered, causing the mana arrow within his bow to expand. Firing it at the Tier V Gastreas at the back as one full arrow. Piercing a large hole on its body before it fell on the ground. Crushing all lower tier Gastreas in the process.

"[Lightning Storm]!"

The sorceress all shouted as the clouds above the sky stared to darken before launching a volley of lightning strikes at the ground.

"Hold your grounds!"

One of the trolls shouted as he smashed a Gastrea with his shield and stabbed his sword at another. 

The gunners all chose close combat as they quickly switched to a shotgun to kill them all in one shot. Creating masive chaos on the walls as the blood of both the enemies and allies drenched the wall.

"Why are they so many of them, today!? They weren't this many for the past 5 years!!"

A general from the human army shouted as he stabbed a Gastrea with the blade connected to the nozzle of his rifle before firing at the Gastreas climbing the wall. Killing them in an instant before falling to the ground.

"Don't let them cross this wall!! It will be the end once they capture our country!"
