Gold and Green

The purple crocodile's scales glowed brightly as the textures on them changed. The crocodile was using Qi to harden its scales, so Alex could notice it with his sense.

He smiled and dashed forwards once again.

The crocodile, this time fully aware of Alex's strength, decided to use its tail to attack him. Its hardened tail had scales growing in all directions like thorns on a flower stalk.

Alex realized that this could be deadly and immediately poured all his metal Qi into his sword and slashed at the tail.

The tail and the sword clashed, and as expected, Alex was thrown back into the sand. 

Alex quickly stood up from the flying sand everywhere and noticed something. The scales on the tail of the crocodile, which was growing in all directions, were now all facing him, and they started shaking a little.
