Passed the Level by Mistake by Entering the Third-Level Rubik's Cube

Qi Yan got a third-order Rubik's Cube by chance. Although it was an ordinary Rubik's Cube, it brought him into a mysterious world. In order to return to the real world, Qi Yan must clear the level according to the instructions of the mysterious world. If he fails to pass the level, he will have to enter the punishment world... What exactly is inside the mirror? Why can't the clown leave the amusement park? Why is there a lifeless but beautiful young woman in the ancient tomb? Why are there no real people in the virtual world? ... After cutting through all the obstacles along the way, I finally cleared all the levels, and I was filled with joy and thought I would return to the real world. As a result, a beggar-like old man suddenly appeared with a strange smile on his face, "Do you think you can return to the real world by finding the right path?" Everything almost made Qi Yan's faith collapse! How did this mysterious world come into being? Is the truth really what the old man said? Why did the old man appear here?
