Next.
Came the main event of this demonstration—the live test.
No matter how much had been said before, it was just empty talk.
To persuade the General Commander, he had to let him witness the combustion effects of High-Efficiency Fuel firsthand.
Cheng Han smiled. "Sir, I have prepared two small Science Magic Internal Combustion Engines. One uses ordinary fuel, while the other is filled with High-Efficiency Fuel, for comparison."
Sword Wanli's tone carried a trace of urgency. "Good!"
"Snap!"
Cheng Han snapped his fingers.
"Whoosh! Whoosh!"
The branches of two Spirit Oak Demons immediately stretched over, carrying two identical internal combustion engines and lightly setting them down before the General Commander.
Two other Tree Spirits each held a wooden barrel with their branches, the barrels containing two fuels of different colors.
One fuel was black and gave off a faint earthy scent.
This was ordinary fuel.
The other fuel was amber-colored and carried a strange fishy sea smell.
This was naturally High-Efficiency Fuel.
Without blinking, Sword Wanli watched as the Spirit Oak Demons used their branches to unscrew metal caps and pour the two fuels into wooden fuel tanks.
Incidentally.
Because the Myriad Radiance People were exceptionally skilled at utilizing plants, most components of these internal combustion engines were made from plants.
For example, the cylinder block was grown from "Rock Wood." This timber was no less strong than steel, yet its density was only fifty percent greater than water's.
The unique "growth-forcing" process could easily create components with complex shapes, which only required some subsequent processing.
In short, the Myriad Radiance People's mastery of plants had reached an astonishing level.
Only core components such as pistons, cylinders, and crankshafts were made of alloy.
A few seconds later.
The fuel had been added.
At this moment.
