Upon entering the Alternate Space, Li Fan instructed Ran Lin to place a dozen pieces of glass into the Materials Laboratory for refinement.

In no time, two pieces of arc-shaped glass, which hadn't changed much, were refined.

Although he didn't doubt the technological capabilities of the Materials Laboratory and was wearing the lab's protective clothing, he hadn't yet tested it in real combat. He had only experienced the thermal insulation and auxiliary effects of the clothing. Li Fan was still a bit skeptical about its bulletproof capabilities, so he asked, "Little Ran, is this bulletproof glass? Why doesn't it seem to have changed?"

Ran Lin was unhappy with Li Fan's skepticism. Pouting, she didn't waste words and directly pulled up the data on the glass, saying, "Its performance exceeds that of bulletproof glass, capable of withstanding 80 density pressure and 1800 MPa stress. You actually already have something like this, called Prince Rupert's Drop, but your current technological level can't solve the internal structural stability, so it hasn't been researched further. The Materials Laboratory merely altered the release point of the internal pressure, creating a closed loop of internal pressure points, making it stronger than Prince Rupert's Drop and eliminating the weak tail point. These two pieces of glass can withstand high temperatures, high pressure, and pinpoint explosive attacks. Unless it's energy weapons, your current thermal weapons basically can't break it."
