The rhino has an unusually thick body, short columnar limbs, a huge head, and is covered with armor-like thick skin. It has a single or double horn above its snout, and a pair of small eyes on both sides of its head. Although they are huge and ugly in appearance, they are timid, harmless and harmless animals. Generally, they would rather hide than fight. However, they are extremely ferocious when injured or in trouble, often charging blindly at their enemies. Jian Ai was like this, either rushing or hiding, but she met Lu Guangqi who couldn't avoid or rush away.
