In the Mecha World, I Am the Only One

The only immortal cultivator in the mecha world! In this world, mechas shuttle across the sky and battleships gallop across the sea of ​​stars. In the fortress made of steel and iron, cannons and engines roared continuously. Xu Sheng came through time travel and was surprised to find that he could actually refine his energy and become immortal! The energy crystal stored on the back of the mecha is actually a rare high-grade spiritual stone! The special metal poured all over the body is all the best weapon-making material. Those weeds and big trees that no one cares about are also treasures of nature and earth that have existed for thousands of years. "What a waste of natural resources!" Xu Sheng shouted in his heart while pocketing various treasures. Refining Qi and cultivating immortality, going against the will of heaven alone! Swallow the spirit of heaven and earth, and integrate the avenue of the universe. When his body crossed the void and his flying sword slashed down the stars. People in this world finally understand that the mecha battleships they have been developing and building are all wrong!
