After settling on a plan to leave Metroplex on Cybertron for the time being, Rimuru didn't linger. He said a quick goodbye to Optimus Prime and Sentinel Prime, and Black Dragon teleported him straight back to his private laboratory deep beneath Cybertron's surface.
He had specially converted the laboratory into a base for cultivation and workshop projects. It was piled high with rare materials gathered from various worlds and fully equipped with dimensional devices, all kinds of magical forging arrays, and technological repair equipment. Its stable temperature and pressure made it an excellent place to work on precision objects.
The moment he landed, the giant Transformation Cog floating in dimensional space slowly descended to the ground. The heavy clang of metal made the floor of the entire laboratory tremble slightly.
Rimuru circled the gear several times. It was far larger than an ordinary mech, and he put aside his usual playful mood and seriously began analyzing it for repairs.
He deployed Black Dragon at full capacity and combined it with Great Sage. Countless streams of data and structural patterns instantly flooded his mind.
But after examining it for only a moment, he couldn't help clicking his tongue. He finally understood how difficult it would be to repair.
It was indeed a core component of a base-former at the very pinnacle of Cybertron.
The Transformation Cog was far more than a simple metal component. It contained Spark-linking runes unique to Metroplex, interstellar energy conversion circuits, and a thousand sets of interlocking mechanisms. Every pattern was deeply bound to Metroplex's original Spark.
The cracks and damage on the surface were only the tip of the iceberg. Large sections of the rune matrix deep inside had collapsed, layers of energy circuits were misaligned and jammed, and there were even traces of corrosion from
