As the metal cube cools, Kyle placed the soldi cube in his tool set. The cube is 5 inches thick and wide, weighing around 10 kilos 

"Move your ass, Kyle. I don't want you to get backstabbed by the facility security system."

As Kyle moves towards Lea, who is heading deeper into the facility 

"Last room, Kyle, either force it or lockpick it, your choice."

The two reach the end of the dark facility where a maintenance room is located, according to the signs all around the hallway 

"The door is jammed. I need you to force it open."

Kyle tried to lockpick the door and failed, so he thought that by brute force the door would budge. Lea kicked the door, causing a loud sound of thud. Even with the force of Lea, the door wouldn't open 

"Let me try something."

Kyle said as he took something from her toolbox and placed a cylinder-like tube beside the door and lit up the other end of the tube 

"Lea, hold it hard with as much power as you can produce."

The end of the tube burns inside. Then a sonic boom is heard and the tube explodes, managing to price the durable door made out of unknown materials 

"Now there's a hole, we can now cut our way through."

Kyle happily takes out his laser cutting tool and ignites the small pen-like tool that releases a thin laser light beam for cutting metalic objects.

"Kyle, I know you have noticed but that explosion just now attracted the attention of dormant dolls inside this facility. Cut this door fast or the security dolls will be here soon and they are equipped with those 50 caliber guns. I can't fight all of them."

Kyle hurriedly cut the door, working his way to the hinges.

A strong ground shake happens on the surface where Aila is standing 

"If this movement of the ground is caused by them, I think they are near the vault."

Aila runs towards the ruins, and when he reaches the ruins, a large crowd of bounty hunters are waiting at the trapdoor entrance 

"Bloody hell mate, those dogs are made out of metal and our weapons won't work. Don't you think we aren't up for this ruin?"

One of the bounty hunters asked another person in the area 

"Hey, don't blame your weapons, see those deactivated dogs, almost all of those dogs under only have a single bullet hole and, according to the investigation team that just went down, if we shoot at the correct location, we can deactivate the dogs."

Both the talking bounty hunters are discussing how to defeat the robotic dogs 

While Aila sneaks into the trapdoor and quietly sneaks past the investigation team and heads deeper into the ruins 

-------------

"There's no end to this, Kyle, hurry up or we are both going to die here."

Lea is exchanging bullets with the security dolls while Kyle is focused on cutting the door using a small laser cutting tool.

"Another 3 mins, Lea, then I can cut this door."

Lea, who had started to run out of ammo, started to improvise with the 50 caliber bullets, creating an experimental grenade using the gunpowder of the bullets 

"Kyle, I don't know how much we can last, but I think this last grand that I made will buy us around 2 minutes, so better finish that door in 2 minutes."

Lea shouted to Kyle as the bullets of the security dolls hit the location where Lea and Kyle were taking cover. Lea threw the grande into the security dolls and a few seconds later, a large explosion happened, causing the ground to shake 

"Finished, get in, get in"

Kyle yells as he finishes cutting the door, revealing 2 metallic closests. One has a padlock and the other one is just a lever for opening 

"Kiel, carry those guns in that gun rack, drop all your tools except the cube and carry those weapons, including that glowing crystal,and face to the other side. I don't want you to see me change."

Kyle follows as Lea instructed, and Lea opens the metal closet that has a doll structure, a replica of Aila and her sisters, a structure with a human-like appearance complete from finger nails to the smallest detail of skin 

"Looks real enough, but we came for what we have been looking for and that padlock is something suspicious. Even a punch from me won't destroy the padlock and I don't want to damage the goods inside by blowing up the cover."

Lea transfers her mircochip and arc reactor to the new replica structure of ancient dolls with the help of Kyle. Transferring both the arc reactor and mircochip has been a walk in the park 

"How good are your hands, Kyle?" managing to transfer the crucial parts of mine into a new body while closing your eyes, your skills as a mechanic are close to our maintenance guy."

Lea finished up transferring the crucial parts of Lea's old structure into the new replica structure  Lea moves with her new body, doing a calibration of the movement as the security dolls are fast approaching. After doing a calibration, Lea picks up a crimson blade in a blade stand inside the room. A black hilt with no blade guard. Lea swings the blade directly into the door and slices it with ease, like cutting butter with a hot knife

"Lets dance"
