In one of the rooms in Fran's house, she was using Telekinetic Hand to toss coal into a simple furnace built beneath a water tank.
After throwing in a certain amount, she focused on the exhaust outlet.
As time passed, an urgent roar finally erupted, followed by a burst of white mist.
A flicker of delight rose in Fran's heart. It seemed this part of her design had no problems.
Using Telekinetic Hand, she directly shut the exhaust outlet she had specifically made to test the seal, then opened the steam valve.
The urgent roar fell silent in an instant, while Fran kept her eyes fixed on the cylinder.
Suddenly, the connecting rod linked to the piston began to move, tracing a semicircle through the air and driving the flywheel into rotation.
However, because the flywheel Fran had commissioned was quite heavy, the connecting rod was not spinning very quickly yet and needed some time to accelerate.
When the connecting rod reached the bottom of its arc, the cylinder expelled a puff of white steam. The rod struck the reversing valve, changing the direction of the steam flow inside the cylinder.
Only then was the connecting rod given power again, continuing in its original direction as its speed suddenly increased sharply.
It rose back to the top of the circle, releasing another burst of steam and carrying the flywheel through another rotation.
Driven by its rotational inertia, the flywheel kept the connecting rod moving in the previous direction, using its kinetic energy to repeat the earlier motions.
With each cycle, it grew faster under the push of steam, and the intervals between its roars gradually shortened.
In the end, the entire Steam Engine let out a continuous roar whose intervals were nearly impossible to distinguish, while the flywheel spun at
