The Road Back from Isekai

Hong Mo, a young boy from Huaxia, unexpectedly travels to a mysterious alternate world. In this world devoid of high technology and filled with ancient martial arts, he discovers he possesses a mysterious power and begins to learn martial arts.

Hong Mo's mobile phone becomes his only modern item in this alternate world, occasionally playing songs. By chance, Hong Mo receives a mysterious text message containing the advanced martial art technique "Lingbo Weibu," giving him hope for rapid strength improvement. Despite the difficult training process, Hong Mo remains persistent.
