Fang Er had no idea what Xiao Qing was thinking; he'd only responded casually.
He couldn't possibly say he was shouting "Grandma!" at the air.
Ignoring Xiao Qing, who stood to the side, Fang Er grinned wickedly as he looked at the golden light in the shop.
His three hundred elite soldiers were about to get a massive boost!
That shining golden object was nothing other than a 7.62*39.
It might even become a bottleneck for technological advancement.
Mo Ming was dumbfounded. He stared at Fang Er, looking wronged, and stammered, "Teacher, d-d-disciple cannot make it."
Fang Er frowned. "Cannot make it? You claim your craftsmanship has greatly improved, yet you can't even make a guide rail?"
Mo Ming: "......"
I said I benefited greatly, alright?
"Come here and learn!"
With a cold snort, Fang Er walked over to a nearby machine tool. Seeing Fang Er step up, the artisans quickly turned off the power, removed the workpiece from the machine, and cleared the area.
He casually picked up a steel ingot, placed it on the drill press, and drilled a hole.
The hole did not go all the way through, only five centimeters deep into the ingot.
Then, he picked up a steel rod and went to the lathe.
He ran a finger over the hole in the steel ingot and began adjusting the clamps and cutters.
The steel rod was firmly secured. The lathe started.
Fang Er controlled the lathe to machine the steel rod.
Fine steel wire was shaved off the rod, turning out in coils.
The entire steel rod looked like it had been stripped of a layer of skin, from the top all the way to near the clamp.
Fang Er repeated the process, machining the steel rod three times. He paused briefly to let the rod cool down, touched it with his hand, then adjusted the lathe and did it again.
The final pass did not produce continuous steel wire, but rather extremely fine steel shavings.
After this pass, he removed the steel rod.
He sawed off the machined end and, holding it in his hand, meticulously refined it with a steel file.
He filed a few times, then stopped to touch the hole in the steel ingot, and continued filing.
His movements were so light that everyone almost thought he was just going through the motions, as no one saw any steel shavings fall.
This was because the shavings were incredibly small.
Grinding, filing, polishing~~
He finally stopped after a full half hour.
Fang Er handed the steel rod and the steel ingot to Mo Ming.
"See if you can fit them together."
Mo Ming tried several times but couldn't insert it at all, breaking out in a sweat from anxiety.
Moreover, when he tried to push it in forcefully, it felt like he was pressing against a spring, and it would even spring back out.
Fang Er asked, "Where do you think the problem lies?"
Mo Ming pointed at the steel rod. "This one should be a bit thicker."
"Is that your answer?"
Mo Ming pondered for a moment, then nodded heavily. "Yes, Teacher."
