The Mecha Age: Am I the Only One Cultivating Immortality?

[Mecha + Passionate Battles + Single Female Lead + Spiritual Qi Revival] While everyone believed that fusing supernatural abilities with technology was the ultimate path, Su Yuan was told by the System that cultivation was the only true way! So while others built mecha, Su Yuan quietly focused on growing stronger. Then, one day, when aliens invaded and the mecha corps were routed, Su Yuan made a stunning entrance! One punch blew apart an interstellar fleet, and one stomp shattered the homeworld of a higher civilization. Standing with his hands behind his back on the borders of the Milky Way, he declared, “Those who attack my Great Wilderness, no matter how far away, will be killed!” (The blurb can’t do it justice, so read the story!)
