"Phew." Xu Tianyu quickly collected himself and continued to ask.
"Dragon, can you find the end of this river?"
"No, I tried before, but I couldn't find the end after walking for a year. In the end, I had to return here because I encountered a terrifying creature."
The flood dragon obviously didn't want to talk about these things, but Xu Tianyu already understood a lot from its words.
The river was longer than he had imagined, and the continent was wider than he had imagined.
Even a demigod flood dragon wasn't invincible. This continent might be dominated by mythical beasts or even creatures of a higher level.
"Sigh, these aren't things you should think about. You should focus on what's happening now."
Seeing Xu Tianyu in a daze, the flood dragon couldn't help but remind him.
"Yes, I'm overthinking. Dragon, can you help me test how deep the sand is? This might be the key to finding Blackgod."
Hearing this, the flood dragon started to spin the sand with its tail. Xu Tianyu quickly hid behind the flood dragon. The sand was too painful.
The flood dragon's test soon ended.
"The sand is about 30 meters deep. After that, there's a layer of soft mud about 10 meters deep. The rest is hard rock." The flood dragon told him everything it knew.
"Dragon, can you turn the sand into a swamp? It's fine if you don't turn it into a swamp. Make it soft and easier to sink in."
"I can try. I haven't tried using my ability on sand." The flood dragon obviously didn't come to this place often.
"No, you can't use it here. Blackgod will discover it, and it will be impossible to lure him here."
Xu Tianyu quickly stopped the flood dragon.
"Think about it. Is there any other place with sand like this?" Xu Tianyu asked again.
"Yes, there are many sand like this on the other side of the river."
As the flood dragon spoke, it stretched its tail towards Xu Tianyu. Xu Tianyu also climbed onto its head.
Crossing the river was too easy for the flood dragon.
Sure enough, the other side of the river was similar to this one. It was also a sandy land.
"Jiao Dragon, use your ability. It's best if you use all your strength."
The flood dragon didn't say anything. The horn on its head suddenly shone, and the colorful horn suddenly turned transparent.
A powerful energy acted on the sand, and the sand seemed to come alive, turning into a quicksand whirlpool.
Whether it was sand or stones, they were all sucked in at a very fast speed. Most importantly, such a trick did not affect the flood dragon at all.
Xu Tianyu, who was on the flood dragon's head, was stunned. No, he was not surprised by the quicksand, but by the horn of the flood dragon.
Because the horn had become transparent, Xu Tianyu could clearly see the glowing key inside.
"I didn't expect this. I really didn't expect this."
Xu Tianyu was amazed. He was wondering where the Flood Dragon would hide the key. After all, the swamp was so big that it would not be easy to find it.
But he didn't expect the Key of the Earth to be the horn of the flood dragon. No wonder, no wonder.
The keys that Xu Tianyu found before were all outside. They were not absorbed by any animals, so it was very easy for him to get them.
