As time passed, new cell phones came into being. The cell phone had been significantly improved in many aspects. Its size had become lighter and easier to carry. Its appearance had also been greatly improved, and it was no longer plump and bloated. In terms of functions, it had a display screen and a flip design. In addition to making calls, it could also send short messages and play some simple black-and-white screen games. This was a big improvement compared to the " big brother."
In modern times, cell phones had undergone earth-shaking changes. The screen became huge and could be operated by touch. The overall workmanship was exquisite, the appearance was streamlined, the texture was soft, and the feel was excellent. There were countless functions. People could buy all kinds of goods online through their mobile phones, use QQ, Weibo, WeChat, and other social software to chat and interact. They could also be used to take photos, videos, surf the Internet, listen to music, play games, and so on. It greatly satisfied people's needs in life, work, entertainment, and other aspects.

The story of the idiot brother and sister losing their cell phonesI recommend " My Mobile Phone Might Have Transmigrated " by the author, The Lost Red Shoes. This book was very special. It wasn't a human transmigration, but a cell phone transmigration. In 2003, Wu Qi obtained his cell phone from 15 years later. He used the novels on his cell phone to speculate on the future trend and started his business. He started from selling lobsters and even dabbled in Social networks. The supporting characters were smart, and the overall plot development was reasonable. Although there were some small flaws, such as the protagonist's messy planning, unclear price inquiries, lack of commercial warfare, etc., and there was almost no description of emotional lines, it was still worth watching. Especially in terms of how to use future information, it was very creative. There was also " Super Godly Phone ", which was about poor college students, a nine-handed counterfeit phone, and a future smart elf. Warhammer: The Midnight Lord's Godfather was a story that traveled through the Warhammer universe. "Ridiculous!" A Druid like you went to cultivate?" It was the story of Lin Yan crossing the cultivation world to find an awakening tool with the Druid profession.
