The entire wall was made of thick alloy, and Lin Xian wasn't sure if it was hafnium alloy; it didn't look like it, but it was already formidable enough that he figured C4 wouldn't blow it open.
This presented a bit of a problem for him.
If he and CC still needed to sneak into Tem Bank in Dream World 600 years later... how would they get past this obstacle!
However, after watching Brother Wang operate and finally open the metal vault door with a password lock, Lin Xian felt relieved.
After all, it was still an electronic password lock, and having CC, the code expert, was enough.
"Come in, Lin Xian, and take a look at our hafnium alloy safe!"
Brother Wang excitedly urged Lin Xian to enter the warehouse.
Entering, Lin Xian looked around.
Just like the photos Brother Wang had sent him, hafnium alloy safes were embedded in the concrete walls on all sides.
Seeing it with his own eyes was indeed impressive.
