Transmigrated into a Grandpa, Embracing the Laid-Back Life

Chapter 296: Your Duty is to Repair Arrays

The underfloor heating in the Formation Hub steward's room was blazing fiercely, a stark contrast to the damp cold that seeped into one's bones from outside.

It was warm and cozy here, with even a faint aroma of "Snow Peak Emerald Mist" tea floating in the air. This spiritual tea was produced from the Cloud Mist Peak within the inner sect of the Cloud Hidden Sect, costing three spirit stones per liang. It had the effects of clearing the mind and brightening the eyes, a rare luxury for cultivators stationed in the murderous aura-permeated Northern Border.

Su Ming stood in the center of the room, head bowed, eyes lowered, his hands respectfully holding the jade slip recording the abnormal earth vein data and that fingernail-sized fragment of insect carapace shimmering with dark golden patterns.

His posture was impeccable, his back straight, yet appropriately conveying deference to a superior.

Behind the large rosewood desk directly in front of him sat a middle-aged cultivator wearing a brocade robe edged with gold thread.

This person was precisely the Formation Hub steward of Iron Wall Pass, an early Golden Core stage cultivator, Wu Miao.

Wu Miao did not immediately look at Su Ming. Instead, he picked up the teacup beside him, gently skimming off the foam with an elegance that made it seem this was not a bloody battlefield, but some pocket dimension for cultivating one's nature.

He took a sip of tea, letting out a satisfied sigh, then unhurriedly lifted his eyelids, his gaze sweeping over the objects in Su Ming's hands.

"You're saying you discovered large-scale demon insect activity underground in Sector C?"

Wu Miao's voice was very soft, carrying a lazy, indifferent air cultivated from long-term high status."Reporting to Steward Wu, it is not activity, but migration and gnawing," Su Ming's voice was steady, striving to make his tone sound objective and calm. "This disciple, through the modified Earth Hearing talisman array, monitored extremely dense vibration sources at a depth of three thousand zhang underground. Moreover, these vibration sources are not chaotic; they have converged into a flow and are currently moving along the earth vein's path toward the area beneath the main foundation of the Heavenly Pivot Position."

Su Ming took half a step forward, slightly raising the insect carapace fragment in his hand.

"This is a sample this disciple collected at the edge of an underground river. This insect's shell is extremely hard, bears dark golden spiritual patterns, and possesses a strong devouring property toward earth-attribute spiritual energy. This disciple speculates this is not an ordinary Earth-Devouring Mole, but..."
