The lengths of Chengdu from QQ Three Kingdoms and "Novice Village" from Wulin Gaiden here are respectively 2 minutes and 1 second and 1 minute and 57 seconds. I listened to them specifically and compared them. I think they are similar. There are some melody parts. Similar, but some parts are basically the same, but the parts before and after the same melody are not the same, so they are not exactly the same.
The music for both online games is produced by Xiaoxu Game Music, so there is no plagiarism. In fact, some of Xiaoxu's music works are completely similar. For example, "Qingyun Mountain·Xin" in "Zhu Xian" is exactly the same as the melody of Longhua Temple in the original "Tathagata Palm".
