The energy-stone fragment that had triggered an internal energy explosion had completely lost its original energy-storage properties.
Even when scattered among the orchards bathed in sunlight, it retained its amber color, as though its energy had been exhausted.
This feeling.
It looked like a small piece of tea-colored bulletproof glass, its surface covered in dense patterns produced by an external blow.
Lü Kuan studied it under the glaring sunlight for a long while, growing increasingly shocked.
Could energy stones actually age?
If there had been no mistakes in the site investigation, then the energy stone had exploded because internal aging had caused a breach to form.
The external Electric Wolf Energy Engine had then acted like a pressure cooker, suppressing the energy and preventing it from venting.
After being suppressed for a long time, the internal pressure had reached a critical point.
Then, under the catalysis of external conditions, the armored vehicle's attack had broken through the pressure cooker, immediately triggering an explosion inside.
But this completely exceeded everyone's previous understanding of the disaster.
Or was it that humanity's understanding of metals was simply insufficient? Perhaps an energy stone was essentially a metal rather than a collection of elements formed from some special element? Realizing this, Lü Kuan hurried back to the edge of the explosion crater, opened the case he carried, and began testing with his instruments.
First was electrical conductivity.
The greatest characteristic of metal was its low resistance. Current could pass smoothly through its interior, giving it strong electrical conductivity.
During the previous tests, the energy stone had been like insulating rubber, with an astonishingly high internal resistance.
Therefore, in terms of energy conversion, they could only first use heat energy to drive an engine, then have the engine convert it into motive power.
Later, although they
