Beacon, if I swim out from here, can I leave the HRE Research Center? ）

[Detected that the specific terrain of this area does not exist in your memory, so no answer can be given.] 】

(Beacon, if I leave the HRE Research Center in handcuffs, do I complete the main quest?) In the water, Xue Qiong hugged herself like a koala on a concrete pillar while asking the beacon in her head.

[It can be considered as the completion of the main quest, but please be reminded that when you leave this world, you must not be out of the attention of any plot character.] 】

(Well, that means you have to run away alone...) Wandering is probably really a cheat option, and you can't even get a free ride in the way of being deliberately caught... In addition, the second basement floor is now a place for Omega Liries' various killings... Xue Qiong squinted her eyes, glanced at the light source in the water in the distance, and decisively dived deeper.

Before, he barely put on a diving suit in the water, and I have to say that the quality of these military supplies is excellent, and he has now dived to a depth of at least twenty meters, and it has not caused any discomfort to him, a person who has never dived before.

(Whew!) The deepest body of water I can remember swimming in is just a two-meter-deep swimming pool... ）

(But my half-mental power development, it seems that there is some enhancement of night vision?) Xue Qiong blinked repeatedly as she swam in the pitch-black water, making sure there was any difference from before, (Well, yes, yes, but in terms of the degree of strengthening, I guess it's not much different from bending a spoon...) ）

"Dangdang!" Xue Qiong knocked on the glass in front of him, and the other side of the glass was shining with a soft daylight light, which was extremely eye-catching under the pitch black water. As long as you break this layer of glass, you can enter the three underground floors of the HRE Research Center, which is the underwater area.

(It's good to use this, I don't know if it's waterproof or not...) Xue Qiong took out the beam saber he had taken from Dr. Takeda's laboratory, but the beam saber that had been placed in the storage space until now, turned on the switch, and the light blade came out without delay, and there was no difference compared to being on the ground, but because it was now underwater, a large number of bubbles rose next to the high-temperature light blade, and the water next to it should have boiled instantly...

(Okay, hopefully I can cut through high-strength glass that can withstand water pressure for tens of meters...) Xue Qiong thought as she pressed the beam knife against the glass and began to gesticulate. On the other side of the glass, several imperial soldiers were looking at him with terrifying eyes, gesturing constantly, trying to stop Xue Qiong, but they were all ignored by him.

(That's right!) If there is a water pressure of tens of meters, wouldn't I just need to open a hole and let it be crushed by the water pressure? Thinking of this, Xue Qiong adjusted her posture, and grabbed a steel pipe fixed to the wall next to her with one hand to prevent herself from being carried by the water when the hole was broken.

(Okay, so be it!) Almost ready, Xue Qiong decisively stabbed the beam saber hard at the thick layer of glass.

"Poof!" Even underwater, Xue Qiong heard the sound.

After Xue Qiong stabbed the beam knife to the bottom, he immediately turned off its power, so that a narrow and deep hole was formed in the glass, and then Xue Qiong took the beam knife back into the storage space, and quickly swam to the side for a distance, watching the changes here from a distance...

"Click! Click! Soon, the glass had a chain reaction under the influence of water pressure, and the spiderweb-like cracks were covered with the underwater isolation window several meters square in a matter of seconds... And then the water began to pour frantically through the bigger and bigger hole.

"Woooooooooo Xue Qiong was almost carried away by the current, but fortunately he was still prescient, first crawling a little farther away against the underwater building, and then clutching the fixed objects around him, so that he was not directly washed into the third floor underground by the strong current.

(Almost, right?) A few minutes later, Xue Qiong felt the water flow calm down, and then looked at the place where he had opened the hole, where the lights that had been on were now extinguished, presumably because something had damaged the lighting equipment in the torrent.

At the same time, there were some human bodies floating out one by one, some floating up and some sinking, and Xue Qiong couldn't tell whether these were alive or dead.

(It should be almost...) Xue Qiong saw that the situation was good, let go of what he was holding, and then swam towards the big hole he had opened little by little.

(Well, I still can't see it clearly from the outside, but before I destroyed it, it looked like a meeting room...) Xue Qiong used the beam saber as a glow stick, and took a few glances at the place that had been washed away by the current, and a leather sofa soaked in water had just floated in front of his eyes.

"Buzz..."The beam saber made some noise as it moved, and it seemed that it only looked high-tech, but in fact it was just a bargain for equipping the lowest fighters...

(Yes, there is also a sealed compartment design...) Xue Qiong swam to an iron door connected to the inner area, and there was a large valve wheel on the iron door, which was supposed to be the kind of pressurized door that required a lot of force to turn a few times to open. It could be seen that this door was very sealed, and Xue Qiong could feel that there was no flow of water from the crack in the door to the next area, because there was no crack in the door at all.

(Do you want to go one layer further...) If this continues, I'll fill the entire basement floor with water... How can I get into an area where there is no water? The oxygen cylinders are only enough for a few hours, although if I open the door and get in, there shouldn't be any water equipment that will come from the outside... Xue Qiong shook the beam saber twice in front of the iron gate, a little tangled.

Just when Xue Qiong was still in a dilemma, he found that the valve on the iron door turned on its own...

(Okay, so you don't have to worry about it now...) Seeing this, Xue Qiong immediately turned off his beam saber, then took out the black dagger used in the previous world, swam to the ceiling of this room, and in the darkness where he couldn't see his fingers, the whole person condescendingly put on a posture...

In Xue Qiong's repeated self-tests, he found that his night vision ability had indeed become better than before, even better than his previous feelings, at least not to the extent that it was better than nothing. And he used to use the beam knife to illuminate, after all, it was just because he was not used to it, and now he is ready to rely on this newfound effect to surprise the person who opened the door.

"Squeak~~" The sound of the iron door slowly opening.

There was no flow of water, and it seemed that the other side of the iron door was also a sealed compartment, and they should have filled that side with water and synchronized it with the water pressure outside before opening the door...
