Yan held her hands apart with circles of formation on either palm, "I'll do a formation to block any fluctuations, you just need to control your own power."
"How long?" Hamar pulled his sword back and raised his stance.
"You got five minutes to take out anyone within the tunnels, I'll isolate from the warehouses and surface. Can you do it?"
"3 minutes. That's all I need."
"Cocky... But I'll trust you know what you know your strength. Just leave one remaining to interrogate...ready when you are." Yan moved her hands apart and touched the ground carefully.
Hamar nodded, "Now!"
Yan pushed her body weight onto the floor and the formations grew bigger and moved under the surface of the ground and isolated the tunnels from the rooms and surface. Any fluctuations from fighting would be hidden while the formations were active. Hamar pushed off the ground and stabbed down, flying down through the building with precision and down into the tunnels. He landed with a thump that those in the tunnels heard easily.
"Go take care of them!"
"What if it's dangerous, shouldn't you come with me?"
"As if. It's probably a random civilian, just slap them and they'd die. Hey we could even offer them to the cause, and if it's a Qi master you have your spear. Stop being a coward and go!"
"O-okay...but it's a girl...I'll take my chance before offering her."
"Freak, go on then have fun!"
The man walked down the tunnels and held a spear in one hand, a torch in the other. The torch held a glowing crystal and illuminated with a red light. He wore a demonic face mask which made him look inhuman. Suddenly as he walked through the tunnels and licked his lips his robes fluttered. He quickly turned his head but instantly his face was grabbed.
Crush....
Hamar crushed the man's head with his strength. He died. Even if he was not a swords masters that reinforced his body with aura, a qi master could not compare to a cultivator of any level in pure strength. Thoroughly dead.
Hamar spat on the corpse, "Filthy...I pray you haven't many victims...poor women..." His face scrunched up and he felt his colourless aura bubble.
"Too Long!" He felt his aura turn fiery with anger and he sent a huge wave into the body which instantly destroyed the laws and turned it into aura for Hamar to absorb.
Not even a mark or drop of blood was left, all was assimilated into Hamar. It wasn't infinite aura though, the aura he had used to kill him and destroy the evidence was merely offset by the aura left from his laws.
Hamar looked at is sword for a moment before dropping his head, "I'm sorry you have to dirty your blade with filth."
Then he jumped forward and bounced off the walls and went through the tunnels at a speed where the ordinary human wouldn't be able to perceive him. Slowly the air pressure built up as Hamar travelled the tunnels, and each person in devil masks he saw was instantly stabbed. Aura instantly sent into their body, eviscerating it and transforming it into pure power.
Finally, only one remained and Hamar restrained his disgust at his constant hearing of their evil-doings. He stood behind the man in the demon mask, him not being able to even sense his presence.
He reached out his hand before stopping and taking a deep breath. Instead of attack he simply observed his connection to Hou and pulled out sleep laws. Any cultivator would easily defend sleep laws since they are so easy to cultivate as they are created when people sleep. However, as a qi master, the demon masked man simply dropped to the floor snoring blissfully.
Hamar flinched and controlled his strength kicking him once before running off back to the tunnel he had made back at the inn. He flew back into the room with Yan and threw down the man's sleeping body, "Done."
Yan pulled her arms back and then upwards, as she did the formation shrunk around the hole Hamar and made and as it rose it helped that hole in the building and ground.
Hamar swing his sword and used aura to burn the remaining blood left on it, "Disgusting...Barely a reason to keep him"
"Why?"
"They feel no remorse and regret, they spoke about what they were doing down there. Other than...immoral behaviour, the real evil behind with the crystals."
Yan seemed to get the idea and brandished her sword to the sleeping man, "Let me guess...the crystals are made by torturing mortals?"
Hamar didn't answer her, instead he punched the air and caused an air blast to knock the sleeping man awake. And before he could sleep, Yan gestured her hand upwards. Flicking her wrist and causing a formation to flash underneath the man. Binding his limbs and gagging his mouth.
Hamar spoke quietly, "Figure it out yourselves, you have techniques. I don't wish to repeat the myself. Disgusting..."
Yan tapped her sword to the demon mask and sent a burst of laws which caused the mask to shatter and expose the scared evildoer.
"Shall we see what you've been doing?" Yan moved with her hand out and touched the man's forehead, at which she pulled back a thread of memories.

***
In one of the underground warehouses a thug with a large stature and a massive battle-axe stopped mid-conversation.
"Halt! Activate the formations! Pour it all in, full blast!" He pushed aside the person he was talking to and his eye became bloodshot.
His chest pulsated with a violet light as his chest was exposed. It was full with various stones of various states of matter. Some looked like a flame, some meat, some wisps of smoke, some space, some stars...It was a collage of spirit stones which he had transplanted onto himself, using multiple laws form these spirit stones, it formed a circle which shimmered.
Inside the circle a shadowy figure emerged, "What is it?"
"I'm nearly done, with all these Spirit Stones and Reversal Crystals I'm almost a cultivator. I'm already at quasi cultivator level and with just a few more of the highest quality Reversal Crystals I can form my Spirit Stone Soul!"
Instead of being amazed, the shadowy figure slouched, "but that wouldn't be why you contact me...or activated the defence formations, now would it?"
"No..no...that's for a different reason. All the operatives in the tunnels have been killed. I didn't detect anything and nothing was heard, it's like they just... disappeared."
"Hmmm...."
