(Apart from anything else, you must believe in the author's music style. There is absolutely nothing unpleasant to hear in the article, I promise.)
Su Xiangfeng, known as the "monster", lost his most beloved sister, but got a mobile phone from another world, or a link to a world where time flows very fast.
This is a fully charged battery with a fully charged signal, which is even higher than the technology in other worlds. This makes Su Xiang Fugui's spiritual world begin to enrich.
This is not an ordinary mobile phone from another world, but a plug-in for the protagonist.
Purpose: Don't be defeated by the darkness of the world
