Once he'd drilled small holes into the integrated metal shell, everything became much simpler.
The self-destruct device was just the usual stuff; remove the trigger and you're done. Qu Jianlei handled it all without even needing Little Lake's help.
Strictly speaking, the encryption on the Teleportation Array Plate that Qu Jianlei used was also a self-destruct system of the same type.
If someone obtained the Teleportation Array Plate and had a Gold Attribute expert like Paranoid helping them, dismantling the self-destruct device wouldn't be difficult.
When he was encapsulating it, Qu Jianlei had already realized this flaw, but he really couldn't completely avoid it.
All he could guarantee was that a Gold Attribute Supreme couldn't safely dismantle the device; if a Gold Attribute Fake Nascent Soul made a move, then he had no way to stop it.
But thinking about it, the entire Empire had only a few dozen beings above Supreme; how many of them could be Gold Attribute?
