Bab 1519: A Black Door!

Then, in less than two seconds, the wall under the big screen suddenly parted to the two sides. This time, it did not split from the middle, but from the side, which was next to the white door, although they could not see the white door now.

Then, another door appeared. This door was no longer white like the first one, but black.

There was only one lock on the black door that could only be opened by turning it.

After the black door was revealed, the wall stopped separating as if it was fixed to this position now.

Jiang Yue pressed the red button that had lit up long ago. Then, next to the black door, a white door appeared, closely adjacent to it.

However, the contrast between black and white was a little obvious.

"It was white before, but now it's black. Does the color mean something?" Xue Yan muttered.
