The Legendary Mechanic

Han Xiao, a veteran power-leveling player in Star Sea, is hurled into the transmigration frenzy by a mysterious force from the East (ahem, the author). With a player interface in tow, he becomes an NPC and returns to the days before Star Sea's open beta. He resolutely chooses the most difficult class: Mechanic.

Warships sail across the stars, stellar mechs twist and soar like dragons, psionic cannons lay waste to the heavens, and an endless mechanical army waits quietly in his personal inventory.

One man is an entire legion!

If not for the players showing up, this would be a serious story about transmigrating to another world...

As an NPC, he has all the standard NPC functions for players... Assigning quests? Adjusting their favorability? Teaching skills?

Wait a second, why do I know all these players?

Well, it turns out the real world has also gone back ten years.
