Aburame Tetsumaru merged back together and immediately discovered a bizarre phenomenon.
His main body on the Planet Fortress had spent several days fighting before finally finding an opportunity to dig through to the planetary core.
Yet for Aburame Tetsumaru, who had been fiercely battling the Otsutsuki God within the core, no more than sixty-eight minutes had passed from the start of the supernova explosion to the moment the core was breached.
Over such a short distance, there was a difference in the flow of time—and a difference of more than a hundredfold.
After merging, the overlap of the two timelines threw all of Aburame Tetsumaru's memories and perceptions into chaos.
His body was far too complex, its sheer size comparable to a skyscraper. His external bodies and clones were scattered everywhere, yet their souls and minds were wholly unified. As a result, Aburame Tetsumaru's biological clock had long since collapsed.
The biological clock was vital data for sustaining life. Without that reference standard, the brain could not govern and coordinate all bodily functions, much less think and judge accurately.
The vast majority of the thought-forms within Aburame Tetsumaru's body were external. His tremendous computational power required better coordination and calibration, making precise timekeeping even more necessary.
Thus, he had changed his method of measuring time, creating specialized time-calibration organs within his body to coordinate his body-wide systems and divide computational tasks among the thought-forms.
The upgrades to those time-calibration organs had allowed Aburame Tetsumaru to achieve tremendous growth. Even after his body expanded seven hundred million times over, he had not suffered a fatal collapse. Instead, he had advanced further in movement, reflexes, combat, and other areas.
Having tasted the benefits, Aburame Tetsumaru continuously pushed the development of his time-calibration organs. They quickly advanced from simple quartz timekeeping to starlight
