(3665) Edge
Tie Hongyan stared at one of the indigo dust and looked at it.
At first, the indigo dust moved towards the edge of the black paper near the edge of the black paper. After only a little movement, it hit the "wall". Because it moved very slowly, it almost did not bounce back, but it seemed that it wanted to get out of the black paper but could not get out of the range. It retreated a little by itself, as if moving towards the edge of the black paper from a farther position helped it break through the "wall". This time, it obviously had a little more impulse. Because it was too strong, it rebounded greatly by the "wall", and it was much farther away from the "wall". The third time, it slowly moved towards the edge of the black paper, bit by bit, no matter how hard it was.
There was a hard rush, but when it moved there, it was blocked by the "wall". This time it did not bounce back very far, and it did not retreat far by itself and then rush again. The indigo dust was at the edge of the black paper. It just retreated a little bit at each time, and then slowly moved a little bit at the edge of the black paper. It touched the "wall", retreated a little bit later, and then moved to the edge of the black paper. It touched the "wall", retreated a little bit again, and moved towards it again, again and again, as if tirelessly, constantly doing things that were not big, always on the edge of the "wall", constantly doing things that were not big.
Tie Hongyan seemed to have a clearer face when he saw the indigo dust.
From the beginning, it seemed a little excited and full of vitality, but later, its expression seemed to become numb. It seemed that there was no hope, but it seemed that it did not give up completely. It was still doing things it had done many times. Although its expression later seemed no longer alive, it never stopped doing that action.
Tie Hongyan suddenly thought of the scene of dripping water passing through the stone. She thought: It was doing it little by little, tireless, and although its expression was a little numb, it kept moving. Will the invisible "wall" be penetrated by it one day, and will it finally rush outside the black paper?
At this moment, the invisible "wall" suddenly appeared, and it was also black like the paper below.
Tie Hongyan paid special attention to the location where the indigo dust kept touching, and found that there was no trace of the "wall" there.
Then the "wall" turned into an invisible appearance of iron red flames. Although it was impossible to see it, whenever she saw the indigo dust, she knew that the "wall" was actually there all the time.
After the "wall" just became something she couldn't see again, the "wall" she couldn't see on the other side also showed black.
Next to the "wall", there were some indigo dust jumping towards it again and again, some bounced back, and some did not bounce back.
After the second "wall" that turned black became back to what she could not see, she saw the "wall" that she could not see before the third suddenly turned black.
Just after the third "wall" that turned black became back to what she could not see, she saw the fourth "wall" that she could not see before suddenly turned into visible black.
The fourth "wall" is closest to Tiehongyan. When the fourth "wall" turns black, the "wall" blocks Tiehongyan's view. She cannot see the indigo dust below the other side of the "wall", but the "wall" soon becomes something she cannot see again.
