The white ice spears shot through the air and into the sludge body, causing the Three Tailed Fox Demon to let out a piercing scream. After which, its movement got even more erratic and aggressive too. The three tails acted independently from the main fox body, making Jin feel like he was fighting four enemies at once.
It became even more challenging when the tails shot their own energy power beams at Jin. He was unable to block them entirely even when he transformed Boo into a bamboo shield.
Block the attack to the chest? The fox demon would aim at his legs instead. If not for the Critical Survival Barrier, Jin would have lost his arms and legs many times over. (Not to mention his head too.)
