The Chongming Sword Box had been successfully cracked without any issues, which was naturally good news for An Jing.
Although An Jing had also purchased the Icefall Rifle for ranged attacks, one could never have too many tactics or trump cards.
Receiving the cracked Chongming Sword Box from Iron Hand, An Jing felt a sense of closeness to it that he'd never felt before... much like a smartphone that had been locked to a specific user, suddenly requiring no password or fingerprint for access.
"Use Essence Qi to imprint on the core, and you will be able to control it," Iron Hand said.
Throughout that day and night, Iron Hand had not rested but continuously worked on cracking the military core of the sword box.
Besides that, he also did quite a few other things, but given his secretive demeanor, An Jing did not pry—curiosity had to be directed correctly.
