In the Aquaculture Lake.
"Hum~"
The Engine droned continuously.
The Floating Log Boat skimmed lightly across the water, sending ripples spreading over the broad lake.
Steward Zhang adopted a humble, inquisitive manner. "Technician Cheng, could there be some reason why the oil yield has dropped by four percent?"
The other two crewmen pricked up their ears, waiting for Cheng Han's answer.
Cheng Han glanced over the lake and answered with a question instead. "Have you noticed something? Since winter began, the Green Rice Shrimp have become a little slicker?"

Steward Zhang suddenly understood. "So that's what it was."
The lanky crewman chimed in, "I thought it was because the water was too cold. So that was the reason."
Cheng Han got to the point. "Secreting antifreeze oil consumes some of the nutrients within the Green Rice Shrimp, especially a substance known as Green Oil Paste.
"This substance happens to be one of the key components of High-Efficiency Kinetic Essence, so naturally, it causes High-Efficiency Fuel production to decline."
Steward Zhang's face was full of admiration. "Your knowledge is truly profound."
The two crewmen nodded repeatedly, looking deeply convinced.
Yet Cheng Han sighed. "Half a month ago, the Cultivation Research Institute in the Eastern Li War Zone specifically sent a notice to every war zone.
"The notice clearly stated that if a specially formulated feed was added to the Aquaculture Lake to replenish the Green
