Trading in Parallel Worlds, Starting with Ancient Poems and Exchanging Fighter Opportunities

In a parallel world, the environment is harsh. In order to survive, the whole people focus on the development of science and technology. After thousands of years of development, the technology of the parallel world has become unprecedentedly advanced. As a price, their literary and artistic development stagnated.

He recited another song, Jian Jia Cang Cang, in exchange for a set of super-intelligent nano-mechas.
