"That's the place." Ōtsutsuki Isshiki nodded slightly. "The underground laboratory... heavily guarded, but not impregnable."
He continued observing, searching for a way in.
Over the past three days, he had identified a few patterns:
Although the electromagnetic barrier around the city was powerful, it performed a self-check and calibration at regular intervals. During calibration, its strength fluctuated ever so slightly!
For a window of roughly three-tenths of a second, an almost negligible "gap" appeared in the barrier. That gap was too small for any normal-sized object to pass through.
But Ōtsutsuki Isshiki's Sukunahikona could shrink any nonliving thing to microscopic size.
He could shrink the equipment on his body, but not his body itself! That was the restriction on living things. However, he could fold the space around his body, making himself physically minuscule.
"Three-tenths of a second... enough."
Aside from that, he also needed to avoid the various sensory barriers inside and outside the city.
Rōran's sensory network was extremely advanced. It included not only conventional Chakra-sensing barriers, but also motion detectors based on electromagnetic fields, "Malice Perception devices" based on causality, and even some energy-monitoring devices he could not understand.
These devices interwove into a seamless net. Any unusual Chakra fluctuation, spatial disturbance, or even "malicious thought" could trigger an alarm.
But Ōtsutsuki Isshiki had advantages of his own.
First, after a thousand years of refinement and compression, his Chakra had reached the point where he could almost completely contain it within himself. As long as he did not actively release it, external sensing devices would have difficulty detecting his energy fluctuations.
Second, his "black eye" possessed the ability to peer into causality! He could "see" whether a particular route would trigger an alarm within the next few minutes and adjust his path in advance. Although he could
