The bracelet was a bit too big for her slender wrist, and then she saw a laser beam from the inside of the ring hit her wrist. She felt nothing, and if anything, the bracelet felt a bit cold. After about three seconds, the laser disappeared, replaced by a series of identical, milky-white squares lighting up one by one from the outer edge of the ring, starting from the laser port in a clockwise direction (or counterclockwise on the other side, of course). This pattern continued in a circle, connecting the ends. All the squares lit up and then went off simultaneously three times, and finally the ring returned to silence, emitting no more light. "Is this thing broken?" she asked, after waiting a few minutes and shaking her wrist.

"Could it be a power bank?" Jiang Youwei wasn't impressed by outlandish product designs. Isn't it enough to just fulfill the basic functions? As for grabbing market share, if you can reduce costs, you'll definitely get your share. "What's the point of all this fancy stuff!" She poked the ring with her other hand, a bit disappointed.

The ring was seen to float without any external force, its center remaining at the center of the wrist's cross-section. Then, light began to distort in the palm of the hand wearing the ring, until it twisted into a "black hole."

Caught off guard, Jiang Youwei's phone was sucked into the black hole. Simultaneously, a small, luminous, milky-white cube appeared on the ring. "Burned phone! My chicken! Give it back! Ah~!" Just as the guy, in a famous display, was about to grab it, the "black hole" suddenly vanished—causing Jiang Youwei to fall.

After calming down, she seemed to have grasped her blind spot: "If you touch the bracelet, you can put things away. Oh, it's a space ring." Jiang Youwei accepted this "setting" naturally. The idea of ​​a time traveler with a portable space is probably a very cliché setting. However, she was puzzled by the question of "how to release the things." "If it can be put away by touching it once, then can it be released by touching it again?"

So her desk was also put away.

"Then touching once is just collecting, what about touching twice?"

She saw two "black holes" appear in front of her palms at the same time, and the chairs and bed in the room disappeared.

"This isn't right, is it? System, can't you explain it? No, wait..." She suddenly remembered that the ring had been spinning slowly while suspended on her wrist. She glanced at her wrist again—the four milky-white squares weren't arranged in a continuous pattern. "Does each square correspond to an object, or does each square correspond to a black hole?" She stroked her chin, as if thinking.

The answer is "one block corresponds to one black hole", and touching the non-luminous area is "collecting", and touching the luminous area again is "releasing". If your memory is good enough, you can even collect and release freely.

Jiang Youwei looked at the bed leaning vertically against the wall, the tables and chairs overturned on the floor, and the mobile phone hanging on the door frame. He rubbed his hair with both hands and nodded repeatedly - portable space is indeed a good thing.
