After having fun in the Azure Dragon Empire, Rias decided to provoke the rest of the other Empires. She knew she could fight them all if she used Juggernaut Drive so she decided to start a full on world war. All the 4 empires against her. This may satisfy her thirst for battle.
She then teleported to the Black Tortoise Empire. She floated directly above the palace. She sensed three Golden Core cultivators in the palace.
She then released some of her killing intent to attract the attention of the Golden Cores. A few seconds after releasing her intent, 3 people flew in front of her. Two were men and one was a blonde woman.
One of the men, with Gray hair and beard and a stern face and a crown spoke first.
"What do you want in my Empire?"Qin Hai asked seriously.
"Cheer up old man. I'm not here for much. I'm just here to destroy this empire and I promise that's all" Rias replied then burst into laughter.
The other man almost looked the same as the other one but looked younger and wasn't wearing a crown.
He got annoyed and shot a green projectile at Rias who just slapped it away. The blonde seeing this seems pumped up. She dashed at incredible speeds towards Rias as she drew a sword from her storage bag.
She slashed it at Rias who summoned the boosted gear and caught the sword with her fingers and kicked the Empress away into a building causing major damages to the building.
Seeing this Qin Hai became worried and asked" What have we done to you to deserve this?"
"Absolutely nothing. I'm just bored and need entertainment which you shall provide." Rias replied nonchalantly as she blocked another strike from the Empress and kicked her off to another building.
"I'm sorry but I have to stop you here." Said Qin Hai as he took out a completely golden sword from a storage bag.
The other man, Qin Dan, the Emperor's brother also took out his sword. Three of them attacked at the same time. Rias started blocking all attacks at the same time.
"Mm you seem more entertaining than those from Azure Dragon" said Rias jokingly.
"So you've already destroyed them?"asked Qin Hai curiously as the three of them were breathing heavily.
"Destroy, No... I merely gave them a warning, like I am doing to you" Rias said nonchalantly not even slightly out of breath.
A certain fighting maniac continued her assault. Her attacks getting more ferocious by the second. A smile was plastered on the Empress' face.
Rias just disappeared and appeared behind her and knocked her unconscious by chopping her on the neck.
"I like her so I'll be taking her with me" She said as she carried the Empress.
"Golden Saint Arts: Golden beam" said the Emperor as he released a technique. A golden light sped at Rias who just summoned a magical circle in front of her and blocking the technique.
"Golden Core Unleash!" Shouted Qin Dan as a enormous amount of green Ki enveloped him. His power seemed to have increased ten fold. This was a technique available to all Golden Core cultivators once a week.
"Unrestrained Ki Slash!" He shouted, waving his sword covered in green Ki at Rias with all the power he has. A large wave of green Ki capable of destroying the three palaces followed the movement of his sword and shot at Rias.
The wave hit her barrier and a large explosion happened crushing most of the palace below turning most of it to dust. The sound of the explosion was heard for miles.
"Did you get her?"asked Qin Hai hopefully to his brother who was breathing heavily as he had expended most of his Ki in that attack. There was smoke at the place where the red haired woman was so there didn't know.
"I hope so" replied Qin Dan. If the attack killed Qin Lao and the mysterious woman then all his troubles would disappear as he had been looking for ways to make his wife disappear 'naturally'.
"That was quite the attack" as voice from the smoke. The smoke was then blown away revealing a crimson red full body armor. It's aura was very strong and it didn't even have a scratch on it. Qin Lao was still on her shoulder seemingly unaffected by the attack as well.
"But you're going to need more than that to injure me much less kill me." Continued Rias.
She then stretched out her hand to face Qin Dan and opened her palm.
*BOOST!*
*BOOST!*
*BOOST!*
*BOOST!*
*BOOST!*
*BOOST!*
*BOOST!*
*BOOST !*
*OVER BOOSTER!!*
Every time she boosted the green gems on her armor glowed. All these boosts happened in 3 seconds. A small red light appeared in her palm.
"Dragon Shot" she says calmly and a large beam of red energy blasts from her palm towards Qin Dan.
Qin Hai wasn't fast enough to save his brother so the was blasted. He was thrown away to the ground. Qin Hai quickly flew to his brother.
Two other Golden Core cultivators arrived. One of then an old woman and the other an old man. They quickly flew to Qin Hai and Qin Dan.
"It seems my warning has been received. I'll be back to finish the job. So be prepared. My name is Rias Gremory, the Ruin Dragon Empress, don't do you dare forget it" said Rias as she undid her balance breaker and teleported away with Qin Lao.
