Previously, by inquiring with the staff of the safe company, Lin Xian learned that safes could be forcefully opened using an "oxygen-acetylene cutting torch."
Naturally, the same applied to the safe in the dream.
He opened his computer and started searching for relevant information.
The online encyclopedia stated—
An "oxygen-acetylene cutting torch" is a high-temperature gas cutting method extensively used in various industrial fields. It's primarily used for the rapid cutting of irregular steel products, such as steel coils, steel ingots, and steel frames, among other steel items that are not easy to secure.
Its principle is very simple.
First, two cylinders of high-pressure liquefied gas are required—one is liquified acetylene, the other is liquid oxygen—both of which are the main combustion materials for the cutting torch.
