Lin Xiao, an ordinary young man who did nothing on earth, died in a ridiculous accident. However, death is not the end, but the prologue of another legend. When he opened his eyes again, he was already in a fantasy continent called the "Secret World" - where monsters are rampant, strong men call the wind and rain, and the remains of ancient civilizations are hidden.
What's even more incredible is that a mysterious interface called the "Void Echo System" appeared in his mind. This is not a common system of immortality or magic, but comes from the endless void he experienced when he died. It can analyze and absorb the "void essence" of everything in the world, and transform it into Lin Xiao's unique power and ability, allowing him to evolve step by step in the mysterious world in an unprecedented way.
From a frail newborn from another world to a mysterious being who controls the power of the void, Lin Xiao must move forward cautiously. He will explore dusty secrets, encounter ancient creatures, and uncover the shocking conspiracy hidden under the surface of the world. But every growth, every "echo" may attract unknown covetousness.
This is an evolutionary path unique to Lin Xiao, a legendary epic woven from the essence of void. In the magnificent mysterious world, can he transcend the mortal world, find the true meaning of his existence, and eventually become the only echo of the endless void?
