Before Alexandra had even finished speaking, a machine larger than three carriages swept backward past the side of the carriage window.
Immediately after, she saw that a wooden tripod more than ten meters tall was attached to the end of the machine.
Startled, she leaned out of the carriage window and saw a huge rope hanging from the top of the wooden frame, the other end tied to a large stone slab fully two meters long.
Seeing that the little girl seemed very interested in the construction machinery, Joseph signaled for Eman to stop the carriage.
About half a minute later, the enormous machine let out a low rumble, and billowing black smoke poured from the smokestack on its left side.
So what had been installed there was an LJ26H High-Pressure Steam Engine.
As the steam engine's revolutions continued to increase, it drove a winch and a series of pulley blocks, slowly dragging the rope on the triangular wooden frame downward, while the giant stone gradually rose into the air more than five meters high.
A man wearing a yellow semicircular woven rattan hat blew a whistle. The twenty-odd workers around him immediately surrounded the machine and pushed hard against the three horizontal bars at its base.
