Capítulo 521: Chapter 268: Two Dragon Tails!_1

By the name itself, it could be inferred that the main ability of Rain-horned Dragon is to cause rainfall.

This ability perfectly complements the Rainy Doll's current skill.

The Dark Nightmare Tiger ingests the Rain-horned Dragon's Dragon Ball, causing the python tail on its back to adapt to the form of the Rain-horned Dragon.

After inheriting the ability of the Rain-horned Dragon, the python tail can effectively assist the Rainy Doll in controlling the arena, expanding her coverage area on the battlefield.

The Rainy Doll's toxins can spread through the rainwater brought by the Rain-horned Dragon.

Originally, the Dark Nightmare Tiger, after consuming the Covenant Blood Essence, only exhibited signs of enlargement. The muscle lines became clearer, and the bones became thicker.

The fur color changed from gray-black to a dark ink black.
