Chapter 38: Stress Reflex
Yako studied the lottery options.
[1 - Stress Reflex (One Breakthrough);
2 - Chunin-Level Chakra Capacity (Stackable);
3 - Wire-Manipulated Shuriken Technique (Entry Level).]
The Wire-Manipulated Shuriken Technique was likely a method for controlling ninja tools with steel wires.
The Longsword Nuibari trailed a steel wire; the blade pierced through enemies while the wire sliced off their feet. It was a formidable weapon.
Chunin-Level Chakra Capacity?
Kushimaru Kuriarare had been the one to kill him. Yako had expected to gain Jonin-Level Chakra Capacity, yet it was surprisingly meager.
Perhaps his current body simply couldn't refine or withstand Jonin-Level Chakra Capacity, prompting the system to swap it for Chunin-Level Chakra Capacity.
