I'm a Locksmith. Isn't It Only Natural That I Know How to Raid Tombs?

[Tomb Raiding + Original Plot + Not Invincible from the Start + No Livestreaming + Not Fanfiction + System] Luo Bin transmigrates to Blue Star and becomes a highly skilled locksmith, only for a System to suddenly appear. This is ridiculous! Luo Bin is a locksmith, so why has he been bound to a tomb-raiding System? System: “Hey! A locksmith can open door locks, right?” Luo Bin: “Uh... yeah!” System: “A tomb entrance is a door with a lock too, isn't it?” Luo Bin: “I guess it is...” With only three years left to live, Luo Bin begins exploring strange, unknown tombs in his quest for immortality. In a gloomy, terrifying tomb, a giant Tang Dynasty zombie rises from the ground. Luo Bin thrusts forward with the Celestial Official Sword, and the giant zombie turns and runs. “Where do you think you're going, demon? I can tell at a glance that you're not human!” In a sprawling, two-kilometer-long burial ground, a Black Phoenix Coffin suddenly flies into the air. A female ghost, appearing to be around twenty, steps gracefully out of it. Luo Bin raises the Faqiu Seal and shouts: “By my command, from the Three Rivers and Five Peaks, let my words resound through the Four Seas and Eight Wastelands!” “With this seal in hand, ghosts and gods alike must flee!” “Heaven Official's Blessing, may all taboos be banished.” “Subdue!” In a gloomy, eerie Han Dynasty tomb, a two-thousand-year-old living corpse is determined to tear Luo Bin limb from limb. Luo Bin cries out: “The immortal path is ever auspicious; the ghost path is ever ill-omened.” “The people sing the Dongzhang chant, to subdue the northern Fengdu.” “Bind the demons and monsters, cut down the six ghost blades.” “All the heavens are filled with vital energy; may my path prosper day by day.”
