Back to the Ruins of Fire, just as the name implied, this was a place where the fiery eye spread.

This sea of fire was extremely wide, extending from the outer regions of the Land of Return to the deepest parts of the world. It was said that the heart of the fire dragon was at the very end of the sea of fire, but no one dared to set foot there.

In this sea of fire, the majority of the spirit beasts that lived were fire-attribute spirit beasts. At the same time, there were also many fire-attribute heaven and earth treasures, so many fire-attribute martial practitioners were extremely fond of them.

As for the Hollow God Fragment that was produced by the fire attribute spirit beast, naturally had the fire attribute as well.

Cang Yun possessed a pure Yang body, and was an extension of his body of flames. Thus, the sea of flames that returned to the Ruins was the most suitable for him to train in, and if he were to encounter any fire-attributed treasures, they would be able to help him cultivate his pure Yang body.

As for Cang Yue, there was no need to even mention the fact that she possessed the five elements, so the fire element naturally suited her as well.

That was why Cang Yun had chosen this place as their trial ground.

About four hours later, Cang Yun and Cang Li finally arrived at the sea of flames that was the Returning Ruins.

As soon as he entered, he could clearly feel the temperature rapidly rising as a scorching heat rose involuntarily.

From a distance, one could see numerous spiderweb-like cracks on the ground in front of them. Within these cracks, a wisp of flame rose.

The flames continued to extend until they reached the end of his line of sight.

However, both of them knew that the end was not the end of the sea of fire. It was just that they couldn't see it with their eyesight.

In this land of fire stood enormous and ancient trees. None of these trees had any leaves left, as if they were dead trees standing on the ground.

Upon closer inspection, one could see that the branches of the trees were cracked and wisps of flames were flowing through them like magma.

What was strange was that this kind of tree could not be burned!

Furthermore, Cang Yun was able to acutely sense that these trees did not die. Instead, all of them had a vigorous life force that could be described as miraculous.

"The Flaming Ironwood Tree is truly a miraculous object. In the boundless universe, there are many wonders!"

Cang Yun looked at the ancient trees and sighed in admiration. The map he had bought had a description of this kind of fire and iron wood.

However, its rank wasn't too high. Because its trunk had been tempered by fire over the years, it had become extremely hard. It was a material used to refine fire-attribute weapons.

On top of the Holy City mission, there was also a special mission to collect fire iron wood. A fire iron wood could be exchanged for a dragon tattoo.

That was to say, the endless amount of Flaming Ironwood in front of him was like a pile of money that had been placed on the ground.

However, this was not the case because the ironwood was extremely hard and hard to cut. Normally, it would take a lot of effort for a stage nine martial practitioner to cut one down. This way, very few people would do such a thing.

After all, the efficiency of earning money was far inferior to that of hunting spirit beasts.

Regarding this, Cang Yun naturally did not have such thoughts.

"Let's go and slowly search for spirit beasts."

In the next moment, Cang Yun and Cang Yue slowly walked towards the sea of flames.

This sea of fire was extremely large, so even though there were quite a few disciples from the Sacred City who had come here to gain experience, so far, Cang Yun and Yue Yang had not seen a single person.

There were also very few spirit beasts around the edges of the sea of fire. Gradually, the two of them disappeared into the sea of fire.
