Yang Xin was from Dongxin Commandery. He had worked in coal mines all along and was highly experienced in mining and geological survey, as well as coal excavation. That was why he had been transferred to the geological exploration team.
Aside from open-pit mining, coal could also be excavated through a combination of vertical shafts and tunnels. In theory, digging a tunnel was no different from mining coal.
At that moment, Yang Xin was gathered with several technicians, writing and calculating on the ground with branches while discussing among themselves. Only after hearing You Fu's question did he introduce the situation.
"Elder You, we've more or less finished discussing the construction plan. According to our field measurements over the past few days, Number One Tunnel is 3,246 meters long. If it were only meant for Endeavor Model Trains, building it would actually be quite simple.
"But the Chieftain said that all the tunnels and bridges on the Qi-Tai Line had to be capable of carrying Heavy-load Trains, so that when the trains were upgraded in the future, the existing bridges and tunnels wouldn't become unusable, forcing us to do everything all over again. We might as well do it properly in one go.
"However, that makes the tunnel much harder to build."
Upon hearing this, You Fu immediately furrowed his brow and said unhappily, "I didn't ask whether it was difficult or easy to build. I'm asking whether it can be built. When can you start work?!"
"Uh..."
Yang Xin was rendered speechless. It was as though a contractor were explaining the technical difficulties to the client, only for the client to impatiently wave a hand and ask outright whether the delivery could be made on time.
He was depressed for a while before continuing.
"Of course it can be
