Transmigrated into a Grandpa, Embracing the Laid-Back Life

Chapter 292: Old Mo

On the tenth day after the battle, the wind and snow at Iron Wall Pass remained bitingly cold, but deep within the Formation Maintenance Camp, inside the "Spiritual Hub Hall," it was warm and cozy.

Su Ming stepped into the hall. Underfoot was warm, smooth jade paving, and the surrounding walls were inlaid with several fist-sized Moonlight Stones, illuminating the entire great hall with crystal clarity. The air was suffused with a faint, calming fragrance, a world apart from the crude barracks outside filled with the smell of iron and blood.

At the center of the hall, dozens of formation plate projections floated in mid-air, slowly rotating, emanating profound spiritual energy fluctuations.

Behind a desk carved from a single piece of cold jade sat an old man with hair and beard as white as snow.

He wore a plain robe without any rank insignia and was playing with a fragmentary rubbing of an ancient formation line in his hand. His gaze was focused, as if it were the most precious treasure in the world.

This person was precisely Elder Mo, the pillar of stability for formations at Iron Wall Pass, a great cultivator at the mid-Golden Core realm.

"Disciple Su Ming, greets Elder Mo." Su Ming performed a respectful bow, his expression reverent, neither subservient nor arrogant.

Elder Mo did not look up, his fingers still stroking the rubbing. With a casual wave of his hand, one of the formation plate projections floating in the air drifted before Su Ming.

This was a standard "Spirit Gathering Conversion Formation," but as the spiritual energy flowed through the core hub, there was always an extremely subtle pause, causing a full thirty percent loss in conversion efficiency.
