There is a colorful comic that I can’t remember for a long time. It seems to be made in China. In the villain, a dwarf has an artifact that is not affected by cause and effect. It seems to be a flower?

Maybe it's "Flowers Are Not Flowers". This comic is a Chinese comic that tells a story about a villain. Among them, the villain is a dwarf who possesses an artifact that is not affected by cause and effect - a flower named "Flower is not a flower". This flower has magical power and can change the rules and destiny of the real world. The story revolves around the struggle between the protagonist and the villain, and is full of elements of suspense, fantasy and adventure.

The other one might be "Figure Mania". This comic tells the story of the protagonist Xiaolin, an otaku who likes to collect figurines. He gains superpowers through a mysterious figurine. This figure can transform into various forms and has immortality. However, Xiaolin gradually discovered that the power of the figures was not unlimited, and he began to fall into confusion and frustration. The story revolves around the adventure between Xiaolin and the figures, and is full of fantasy, combat and emotional elements.
