It could only be seen when approaching within several hundred meters. This green smoke simply couldn't be seen before that.
There was a large pit over a kilometer in width and over a hundred meters in depth. The surroundings of the hole were filled with cracks that seemed to have experienced the passage of time.
The green smoke was rushing out of the large hole, and when they approached it and saw what was within, everyone was stupefied. Reina even paled, her legs shivering.
Lin Yun's pupils suddenly shrank as he let out in alarm, "How could there be an Ancient Poison Dragon!?"
In the hole, a huge Dragon covered in dark green scales and spreading over two hundred to three hundred meters was calmly lying there. This Dragon's eyes were tightly shut, and unlike the current era's Dragons, who only had thick hind legs, this Ancient Dragon's limbs were all bulky, and every paw had five claws, two more than most of the current Dragons.
