In the blink of an eye, the serpent's body that occupied the entire passage was split in two by the powerful Sword Qi. As the Flying Swords severed the serpent, the half of its body that was connected to the depths of the cave suddenly retracted, leaving only the front half, which carried the serpent's head and continued to move towards the cave entrance due to inertia.
After watching the latter half of the serpent's body withdraw into the depths of the cave, and confirming with his Divine Sense that it had indeed retracted, Dong Tianyu then emerged from the Cave, chasing after the area where the front half of the serpent lay.
By then, the front half of the serpent's body had lost its original force, and dark green blood was splattered all over the cave passage.
Looking at the cleanly cut cross-section of the serpent's body, Dong Tianyu waved his hand to collect it into the Cave, and immediately began to decompose it.
