I believe that many middle-aged friends are familiar with the Fairy Sword series games as well as the author, and this domestic PC game, which has grown with the post-90s generation, has now entered the seventh series (except for external rumors). At present, Daewoo, the creator of Xianjian's game, has publicly stated that this time, the game engine has been changed from Unity3D of Xianjian 6 to a higher level UE4, and the development cost of Xianjian 7 will be up to 67 million yuan. The development cost of 67 million yuan is not only the most expensive game in the history of Fairy Sword, but also very rare in the history of domestic games (probably the most expensive domestic stand-alone game).

Yao Zhuangxian, the father of Xianjian, has previously publicly disclosed that the input cost of Xianjian 6 is 20 million yuan, which means that the input cost of Xianjian 7 this time is three times that of the previous generation. Although the purchasing power of RMB seems very weak with the central bank's water release, M2 growth and house price rise in recent years, 67 million yuan is a very high investment in any case. According to the consistent pricing of Xianjian, its digital version is about 50 yuan, so its sales volume must be more than 1.5 million yuan to ensure profitability.
