After quickly killing the lightning tiger in front of him, Gu Yuan recovered his spiritual energy, then picked up the knife in his space ring and quickly decomposed the body of the lightning tiger. He collected all the tiger skin and claws into his ring without wasting anything. He then cut off the fattest pieces of meat from the lightning tiger, put them into his ring, and then buried the lightning tiger on the spot.

The smell of blood could attract many monsters, so Gu Yuan did not dare to be careless. He had no choice but to use red flames to burn the remaining body of the Lightning Tiger and then buried it underground.

In this way, the bloodstains will be completely evaporated and the bloody smell will be burned away by the red flames, which will make it much safer.

This long experience had become a habit for Gu Yuan. After every battle in this kind of environment, if there was even a trace of blood, Gu Yuan would thoroughly clean it up, to prevent any trouble later. This would be more trouble than it would take, so it would be better to completely clean it up before leaving, saving himself the trouble. It would also be extremely beneficial to him.

After identifying the direction, Gu Yuan looked at the ground. There were some messy traces on the ground. He thought about it and it must be from the Lightning Tiger.

Thinking of the shape of the claws, Gu Yuan compared it with the ground and could clearly see the range of activities of the Lightning Tiger in this area.

Gu Yuan followed the footprints on the ground, found an area with dense footprints, and continued walking forward. It didn't take long before Gu Yuan came to a place with the densest footsteps.

But what was strange was that the footprints disappeared here. Gu Yuan frowned and continued to look forward, but he could no longer find any traces, except for some traces on the road he had just come from.

"What's going on? The footprints are clearly here, why did they disappear here?"

Gu Yuan looked at the ground in confusion, his brows furrowed even more as he muttered, "Could it be that this lightning tiger flew here? Impossible! If that were the case, I wouldn't have been able to kill it so easily. This means there's probably no such place in the desert, but rather that the lightning tiger relies on something to absorb lightning energy, and then becomes a lightning lake."

Gu Yuan looked at his feet. Since there were no footprints around, could it be possible that he was underground?

Thinking of this, Gu Yuan looked at the sand under his feet and then squatted down.

He summoned spiritual energy from his hands and dug all the surrounding sand to the side. After digging for a while, he didn't find anything obvious.

Gu Yuan, a member of the team, murmured, "That's impossible! It clearly disappeared right here. This Lightning Tiger must have a hiding place nearby. Otherwise, in such a harsh environment, not only him, but even I wouldn't be able to withstand it. Furthermore, with water resources so scarce here, Lightning Lake doesn't have the capacity to prepare water resources."

Gu Yuan continued digging underground. Since there was no place on the ground where such a thing could exist, it could only be underground.

After digging for a full half hour, Gu Yuan finally made a new discovery. The sand underneath suddenly became extremely loose, indicating that this place had been buried before.

"There really is a hiding place!"

Gu Yuan laughed excitedly, and as he looked at the underground cave that was gradually revealed in front of him, he couldn't help but feel excited.

After thinking about it, the red flame in Gu Yuan's hand shook, and a beam of fire shot out from Gu Yuan's hand and was thrown directly into the cave underground. Finally, the red flame burned wildly in the cave.

After half an incense stick of time passed without finding anything special, Gu Yuan walked in with confidence.

Use the red flame to test whether there are any little tigers or the like inside. This is also where Gu Yuan is more cautious. If there is something inside, Gu Yuan will have no chance of escape once he goes in. He can only be forced to fight underground. The surrounding sand may be collapsed by the aftermath of the battle, and he may even be buried. This is extremely fatal to Gu Yuan, and Gu Yuan is unwilling to take this risk.

Fortunately, after making sure it was safe, Gu Yuan jumped directly. After going down, Gu Yuan's body actually stayed in the air for a full ten breaths before falling to the ground. Gu Yuan looked at the sand under his feet in surprise. At this time, it was no longer sand, but solid land, very solid.

Gu Yuan stepped on it hard, but there was no trace of it.

His heart began to beat faster and faster. There was such a place in the desert, and it was not even sand. It was obviously an extremely strange thing.

However, Gu Yuan also accepted this discovery. After all, this place is likely to be a relic or something like that.

Because Gu Yuan had heard before that there were many ruins in this desert, so Gu Yuan was not surprised now. He was just more worried about whether there was any terrible existence in this ruin. If so, then Gu Yuan would definitely run for his life instead of caring about these ruins and the like.

Exploring the ruins was fine, but the first thing to do was to ensure his own safety. This was Gu Yuan's number one priority. If there was any danger, he would stay if he could handle it, and would flee if he couldn't.

Looking carefully at the underground environment, Gu Yuan found that there was no lighting here, and it was pitch black in front of him. He shook his head helplessly, and the red flame in his hand swayed out.

The power of the red flame has now greatly increased, and at this moment it has become Gu Yuan's lighting tool.

Gu Yuan couldn't help but laugh, "Chi Yan, I never thought that one day you would become something like a candle."

The red flame flickered, as if answering the employee, "Isn't it your fault that I became a lighting tool?"

Gu Yuan shook his head, suppressed his facial expression, and walked forward.

The underground showed a place that had existed for a long time, because Gu Yuan could clearly see that there were some buildings on it, not just sand, so Gu Yuan could judge that this was a place that had existed for a long time, and it was relatively old, and there were even some bats and other things in it.

Since this place has existed for a long, long time, could it really be a relic?

He became alert in his heart. If this was a relic, then he would have to be extremely careful. This lightning tiger might have stumbled here by mistake, or it might be some kind of guardian monster.

However, Gu Yuan was not overly worried. If nothing worked, he would just run for his life. After all, it would be a pity not to explore such a place.
