The flank is equivalent to the position of the human liver.

The scientific name of the facility here is the Separation of Impure Substances, which is commonly known as the desalination plant, which literally means that the resources extracted from the offshore oil fields must be desalination before the resources can be used for other purposes.

"Huh? What's going on with this gate? ”

After the three of them came to the flank area along the fork in the road, they suddenly noticed that there was an extra gate at the entrance to the flank area.

The door itself takes the shape of a gear, the same color as brass, and is buried at the entrance to the flank area, cutting off the space on both sides.

The overall diameter is about five meters, and there is a lock hole in the center, as if signaling that the key is to be presented.

"Is this gate ......?"

Meltrilith's eyes widened the moment she saw this gear gate, and a thick speechless look appeared on her face, "BB, did you actually copy this thing?" ”

"Lilith, is this a special door?"

Fujimaru Rika asked a little uncertainly.

"Well, very special."

Mertellilith nodded, and replied with some unhappiness: "In the world of the Moon Grail War, BB used to use this kind of door to divide I don't know how many floors and areas. ”

"Don't look at it so inconspicuously, but in fact, this gear door separates the space on the left and right, and it is impossible to force it through, and the only way is to find the corresponding key."

Separated the space?

In other words, the space on both sides of the gear door is no longer a world?

Except for spatial transfer, I'm afraid there is no means to break through here.

But it's a pity that none of the three of them can transfer space, that is, they can only obediently look for the corresponding key.

"But, with such a big deal, where are you going to find the key to a door?"

Fujimaru Rika suddenly had a headache, "Besides, I have a bad feeling that this gear door is a specialty only here, or is it that all the other areas have been added with gear doors......

These words, even if Lu Xia heard them, they couldn't turn a deaf ear.

If BB did add these gear doors to all the remaining areas, it would be almost impossible to explore the whole area, and the hell knows where to find those keys.

"With BB's character, if she did have the key, it would have ......," Meltlis looked down and pondered.

And just when a few people fell silent—

"Ahem...... Ahh......h Test, test. ”

A very familiar sound of underbeating reached the ears of the three of them through the radio.

Then, just like yesterday, a virtual image that seemed a little unreal was projected in front of the eyes of the three of them, standing in front of the gear door.

Looking up, the girl with long lilac hair, wearing a black stand-up collar long-sleeved trench coat, a miniskirt and black lace stockings is not the same super AI with bad intentions and a very hot person, BB?

"Okay! So this time, the host is still BB Sauce, the ruler of the moon side! The Sheep Senior, No. 2, and her entourage, welcome you on a journey of true discovery! ”

BB cleared his throat with a look of pride and complacency on his face, "This time, I'm here to add new rules to Senior No. 2. ”

"Sure enough, I knew it was so."

Meltrilith pursed her lips, a sneer on her face, "No matter what world you go to, you're still so annoying, BB." ”

"Melt is, I really didn't expect that you, who hate humans so much, would choose to act with humans."

BB looked at Meltrilith with a skinny smile on his face, and a discerning person could tell at a glance that the two were going toe-to-toe.

"Is it true?"

Fujimaru Rika was taken aback, and couldn't help but look at Meltrith Lilith in some surprise, "Lilith actually hates humans?" ”

Along the way, Mertrilith followed her instructions almost safely, without the slightest rebuttal or dislike for her, which made her feel very favorable.

"Don't worry too much, I really hated humans before, and I wish all the humans in the world were dead."

Meltrilith said disapprerovingly: "But compared to the past, I have grown, even if it is AI, it has the right to grow itself, right?" I can't always be like a child, holding on to willful thoughts. ”

"I do hate human beings now, but I don't hate the shining places in human nature, if I have to say it, I have to learn to see the good in others."

As she said this, she looked at BB with contempt, "Unlike a super AI who once tried to destroy all of humanity, I am not as extreme as hers, nor do I have such a third-rate view of love. ”

"Whose view of love is third-rate! At least in the middle of it! ”

BB puffed out his cheeks as if he was very angry, bared his teeth at Meltrilith, and then snorted coldly, "Forget it, this time I'm here to announce the new rules to Senior Two, so I won't worry about you for the time being." ”

"All in all, at the moment, all areas except the thigh area and chest area have been equipped with gear doors, and you must use the corresponding key to open the door and enter the corresponding area, which is a very fair rule, because this is the rule for everyone."

A smug smile appeared on BB's face, waving the silver whip in his hand, "And if you want to get the corresponding door key, you have to pay a terrible price, I wonder if Senior No. 2 has the courage?" ”

"Let the horses come!"

Rika Fujimaru waved her arms and let out a majestic cheer at the BB, as if she was going to face it without hesitation, no matter what difficulties she encountered in front of her.

"Beautiful enlightenment!"

The look on BB's face became more and more proud, and then with a flick of the whip in his hand, a half-human-high crystal platform appeared in front of the gear door.

On top of the platform, a transparent cube about the size of a head floats, and in the center of the transparent cube is a brass-colored key wrapped in it.

"Inside this cube is the key to the flank area, please come up and touch it!" BB smiled like a philistine on his face and urged Fujimaru Rikato.

Rika Fujimaru took a deep breath, then stepped forward and placed her hand on the transparent cube.

"Please pay 20,000 cherry blossom coins!"

The sound of mechanical texture coming out of the cube seems to be without the slightest emotion.

"It's too expensive!"

Fujimaru Rika's eyes widened suddenly, and she exclaimed in surprise, and her previous spirit of no hesitation was gone.
