A Useless Mechanic? Start by Summoning a Star Destroyer

[Game world + lack of firepower phobia + invincibility + no heroine + funny] In 2024, a "catastrophe" event occurred on Blue Star, and the game world merged with Blue Star. Monsters that originally only appeared in game novels are rampant in Blue Star. Only by becoming a professional can we compete with them. Since then, Blue Star has entered an era of comprehensive job transfer. Eighteen years after Lu Xing became a soul and traveled to Blue Star, he awakened a recognized useless profession during the awakening ceremony: mechanic. As we all know, the mechanic's level 1 skill "Self-Explosion Robot" is recognized as a garbage skill with slow speed and small attack range.

Level 5 Skill "EZ-8 Land Combat Mobile Suit" Level 10 skill "PB-72 Space Bomber" Therefore, Lu Xingcheng transformed into a mobile fortress commander and worked hard to cure the phobia of lack of firepower.
