"Bang!"
A large stack of textbooks sat on the small table in the corner, standing half a meter high. They had clearly been thumbed through countless times. The page edges were curled and blackened, and the covers had been wrapped in transparent tape until they gleamed.
"Textbooks on various types of firearms. The top five are about Remote-controlled Vehicle-mounted Machine Guns," Weng Lianggong explained.
"Thanks!" Song He picked one up and opened it. Inside were lengthy theoretical discussions accompanied by engineering drawings of firearm components.
"Although these textbooks are outdated, they're still classified. According to regulations, they can't be taken out of the firing range. If you really want to build a Type 80 Rifle, you can come here whenever you have time," Weng Lianggong said hesitantly.
"I probably won't be coming often in the future. I'll finish the Type 80 Rifle before tonight."
"How could you possibly do that today?" Weng Lianggong said. "To properly learn all these textbooks, you'd need at least a week or two!"
Song He smiled at him without explaining further and lowered his head to read.
Weng Lianggong left helplessly, saying no more.
Song He swallowed several capsules. His eyes shone brightly as he scanned the textbook contents.
Electromagnetic Solenoid Firing, Trigger Linkage, Gas Block, Piston Cylinder, Piston Tail Regulator...
Ejection Rod, Shell Pusher, Extractor Hook, Bolt Tilting Lock, Offset Locking, Four-Bar Linkage Locking...
Muzzle Climb Compensator, Barrel Locking Key, Single-Path Feeding, Right-Side Feeding, Folding Front Sight...
Mathematics Progress detected. Rising from Platinum Level 46 to Platinum Level 47!
A Mathematics Progress notification had actually appeared before his eyes. Perhaps the system had judged firearm structures to be mathematical structures?
Sweat beaded on Song He's forehead. The complexity of firearms exceeded his imagination. Dozens of designs had emerged for every component. Generation
