The main war begins (5)

As soon as One Sword crushed the jade slip, there were two balls of light that appeared, entering both him and the turtle.

This jade slip contained a temporary contract with the turtle True Spirit Beast and once One Sword crushed it, he would become its master.

One Sword was a sword cultivator and in normal situations, sword cultivators wouldn't need pets because of their power. However, there were certain situations where sword cultivators would take pets.

Sword cultivators were powerful because of their mighty attacks, but it was because of those mighty attacks that they also had a flaw. 

They were lacking in defense!

This was usually solved by sword arrays or using powerful attacks without care of defense, but those weren't proper solutions. They were just a way of patching this deficiency and not solving it.

The real way to solve it was by using a pet with a defensive ability, like this turtle.
