In a small dimly lit room in the laboratory, a black hole suddenly appeared in the air, and in the blink of an eye, the hole shrank smaller and smaller until it dissipated.

The interval between the appearance and disappearance of the whirlpool was less than two seconds, but such a brief moment also made the big black dog, who was lying on the ground listlessly, instantly alert, arched his body, bared his fangs, and a loud roar was about to blurt out......

However, the next moment, the big black dog rolled his eyes, revealing the whites of his eyes, and with a weak wail, he collapsed to the ground, not knowing life or death.

At the same time, Xia Xi, who threw a level 10 powerful potion into the dog's mouth, received an urgent reminder from his mind: You have found out, please fight quickly!

According to the previous instructions, the invisible Xia Xi quickly put an unpretentious gray iron bead under the big black dog's buttocks, and the alloy ground below immediately reacted, slowly pulling out a square groove on both sides, and an ordinary Rubik's Cube lay inside.

When Xia Xi took out the Rubik's Cube halfway, a sharp knife had slashed at her head with the sound of breaking through the air, but she didn't move.

Seeing that one move was missed, the dark guard continued to slash the second, third, and fourth strikes......

Other guards hiding in various locations joined the killing team......

The alloy door was opened by the guards outside with a special key, and more than a dozen zombies wearing gray and silver armor and holding long swords swarmed in, slashing and stabbing into the air......

At the same time, the siren installed in the corridor sounded a piercing and lengthy alarm, and the small room suddenly turned red, and various surveillance cameras installed in the corners, cracks, and shadows lit up with scarlet dots, and the lens of each camera was aimed at Xia Xi, moving with her movements.

Xia Xi, who was walking in all kinds of deadly attacks, had already put away the Rubik's Cube, and her body was fine except for some minor scratches, and at the same time, her head was about to burst! Urging kept ringing in her head, and every sentence meant the same thing, so she quickly found a place where there were no zombies and went back!

But she doesn't want to do it yet, because she's on a treasure hunt!

She looked left and right, this small room was a little messy, there was no furniture such as tables, chairs, shelves, etc., it looked like an ordinary utility room, and things were placed in a disorderly manner, as if they had been discarded here at random......

Xia Xi quickly looked around, and suddenly found that there were a lot of zombies in a certain place, although they also attacked her, but they didn't seem to leave that place much, behind them, there were many boxes, iron blocks, unknown strange shapes......

Xia Xi nimbly walked through the gap between the zombies, and soon came to the pile of things, and without thinking about it, he picked up these things as much as possible......

Suddenly, Xia Xi, who was moving things, found herself as if she was surrounded by zombies, and behind her was a hard alloy iron wall......

This time, the cave closed very quickly, closing almost the moment Xia Xi disappeared, not giving the zombies a chance to pick up the hole, however, at the moment when Xia Xi disappeared, a black gas entered.
