Queen look at the lake and walk to the wall nearest to the pier she pushes some rocks and instantly a hissing sound as hydraulics works, A door size rock wall was pushed out before moving to the side, a small room was presented to Queen, she steps inside, and inside all kinds of weapon was displayed on the right and left wall and in the front, a small laboratory can be seen it's a portable lab. That she has stolen from HFA Intelligence HQ.
This portable lab is an experimental lab that can produce a serum that can put people in a very suggestive psychological state that makes them very susceptible to mind control, she was supposed to undergo a mind control operation, fortunately, she found out in advance, so she plans ahead of time.
Fortunately, she was successful and found out where the lab of mind control serum is produced, so she infiltrates the lab that's located in the wilderness she killed all the guards and tortured the scientists in order to find out how the serum is produced a how it worked.
She then stole all the equipment she can take into a small aircraft in the back of the lab. She took all the data and killed all the scientists who know about it and at the same time she has stolen 5 portable labs that can produce the mind control serum and left for Enigma City, but not before she blows out the lab using explosives.
HFA intelligence found out what happened, but it's already too late she is long gone by then.
Unfortunately for Queen, her travel to Enigma is not smooth sailing she encounters an electromagnetic storm as the aircraft she's taken is not built for that kind of event she crushed landed somewhere near Enigma City.
Unfortunately, many types of equipment she stole were destroyed when her aircraft crashed and among the 5 portable labs, only 1 survived the rest is destroyed beyond repairs. Along with many experimental devices, she buried the wreckage and made her way to Enigma City, it took her years before she has strong enough force to retrieve the rest from the wreckage, and those that survive the wreck is in this secret room.
HFA did its best to look for the culprit behind the destruction of one of their important lab. And because Queen manages to hide her trail well, it took them several months before HFA figure out who was behind the incident. They tracked her into Enigma City but by then Queen has managed to build a strong force using mind control serum.
So they are powerless as Queen kills every agent HFA sent after her. And unless they send a big force they are powerless to do anything to Queen. So they tried to negotiate with her, but Queen won't budge. She's an orphan, so she didn't have any attachments the HFA can use against her.
Since then many of the HFA lab on earth has been completely restructured and reinforced to prevent another accident, unfortunately, Earth is still their biggest supplier of materials so many of their labs and factories are located on earth albeit in a very safe place away from normal people.
Queen looks around the room and sighs the portable submarine she has only had limited space, that's why she's so adamant in retrieving the experimental inflatable submarine, so she can take all the things here and maybe some of her most trusted men away from here. She knows that when she leaves here the likelihood of her being able to come back and retrieve the things here is close to zero. She packs up the portable lab carefully this is her bread and butter without it, she won't be able to keep herself alive for long.
10 minutes later the portable lab is safely tucked away into a small box around a meter in diameter.
She carried it to the inflatable sub and barely put it inside without breaking anything inside the inflatable submarine.
She looks back in the room and sighs, she can probably take one or two more items inside the room. She took an experimental laser gun and a few more small weapons, and put on an experimental exoskeleton, and contemplate whether to destroy all the remaining items inside, eventually, she chooses not to and just closes the door. Now any trace of the room is gone she only wishes the room remains undiscovered until the day she will be able to retrieve it. She chooses not to destroy it as that would require an explosive to do it.
And using explosives may cause her men to forcefully come there to check if she's ok. And when they did they will discover that she is running away all by herself, even then she didn't know how they will react even if they are under mind control.
She looks back once again in the tunnel leading back outside, after a few seconds resolute eyes can be seen in her face, she boarded the submarine the hatched closed and after a few seconds, it started to dive.
Queen, leader of Underlady one of the Head of Enigma City disappeared, it was years later when she surfaces again into the world.
Biggs has no idea that Queen is no longer in the cave so is Queen's men, they continue to fight back and fight hard they did, disregarding their own lives.
The Grand Army along with 500 combat droids storm Queens lair.
It turns out Biggs is just overly cautious as most of Queen's men are just regular humans and very few are enhanced so the droid and Army made quick work of them the only problem is the cave is just really too big. There are so many tunnels and corridors leading to dead ends luckily the drones can speed up the process of mapping the cave.
4 hours later the cave is purged from Queen's men. And until the very end, no one entered the golden doors, all of them died still believing in their Queen. Many of them committed suicide instead of being captured. In the end, all of them perished.
Biggs sigh when he heard the reports, the golden door leads to a small lake and Queen is nowhere to be found. According to the drones, it leads to the Yellow River. The Yellow River is full of mutated monsters it's one of the forbidden rivers in the world.
"There no need to look further. Call back the drones we can't lose too many of them at the moment. Forget about Queen for now. Clear the cave and secured the surrounding area." Biggs ordered.
"Yes, sir."
"Sir we found a hidden room near the lake in the cave."
Hmm. Biggs looks at the monitor showing what's inside the room, the rocky doors were cut by the laser by the drones. It was the drones that located it...
"Transport everything inside to the temporary HQ and have them analyzed."
