Only Two

Words are the most powerful way to convey a message. Not everyone knows sign language anyway.

Dreamer's words weren't fabricated, he only said what he wanted to say.

And that's why it resonated with everybody who heard him.

"Alright. Let's go inside now." Dreamer said and without waiting, went back inside the city.

As soon as he entered, he stood beside the gate and held the lever.

He waited for everyone to enter and when they were finally inside the city, Dreamer smiled.

"I wanted to do something like this as well." He said and pushed the lever up.

RUMBLE!

The door made a sound and started lifting up, closing once again.

"It takes five seconds for the door to close and open. That's enough time I guess." Dreamer observed the timing of the door.

"And the fact that no one can easily see the door is also an added security. Right, boss?" Tesla added.

"Yeah. Good work." Dreamer praised Tesla again.
