The clamor in the laboratory had already continued for three days and three nights.
Fan Yu was like a ferocious beast trapped in a cage, his eyes bloodshot as he paced frantically around a half-finished metal cannon barrel.
"No! Still no!" He irritably clawed at his already sparse hair. "The energy output is unstable! The frequency fluctuations that ignite the 'shell' are too great—it works one moment and fails the next! If this thing went onto a battlefield, it'd be like opening a blind box!"
Several researchers who had been dragged into the laboratory as laborers remained silent as cicadas, terrified of provoking this Rank 8 Soul Engineer.
Huo Yuhao set down the blueprint in his hand and slowly walked over, pointing at the huge, cumbersome Soul Power storage array connected to the cannon barrel.
"Teacher, the problem might not lie with the 'igniter.'"
"Then where is it?" Fan Yu roared impatiently.
"It's with the 'fuel tank.'" Huo Yuhao said calmly. "Our fuel tank is too primitive."
"Fuel tank?" Fan Yu froze for a moment, then realized Huo Yuhao was referring to the Soul Power storage array. "This is already the best energy-storage core the outer academy can provide! What more do you want?"
"Teacher, look. This core was designed to power ray guns, so it prioritizes sustained stability. But our 'shells' need an instantaneous burst. Asking a quiet lady to fight bare-knuckle is bound to leave her unable to let loose."
As he spoke, Huo Yuhao casually drew a square on the nearby light screen.
"Why don't we make the 'fuel tank' into a standardized component too?"
"The 'batteries' we discussed before don't just have to be one-use 'shells.' We can also make rechargeable, universal energy blocks!"
The moment he finished speaking, Fan Yu's breathing stopped once again.
"Universal...
