Therefore, although Uchiha Chi had failed for many years to successfully develop a unique Space-Time Ninjutsu like the Flying Thunder God, he had carved out an alternative path. Using Yin-Yang Release as his foundation, he painstakingly researched and developed a Secret Jutsu specifically designed to disrupt space-time transmission, and even modified a version that could be activated with the Mangekyou Sharingan.
Once used, this Secret Jutsu could generate an interfering effect within a certain area around Uchiha Chi's body, effectively preventing others from launching sudden sneak attacks against him through Space-Time Ninjutsu or Dojutsu. Even if it could not completely stop them, it could delay the moment when the Space-Time Ninjutsu or Dojutsu took effect, buying him ample time to respond.
With this powerful Secret Jutsu in his arsenal, when facing Space-Time Ninjutsu or Dojutsu, Uchiha Chi was as if draped in an indestructible protective shield, causing Ōtsutsuki Isshiki's numerous attempts to use Sukunahikona to end in failure.
