Xu Tianyu didn't find any useful information, so he continued to move forward.
This time, he walked very slowly and carefully observed his surroundings.
He began to develop a strong curiosity about this unknown force that was killing animals.
Sure enough, not long after, he found another burial ground.
But this place had obviously been here for a long time.
The bones of the animals had changed color, and there was a lot of fungus around.
And there was a very disgusting smell in the air.
"This smell is a little familiar. I think I've smelled it somewhere before."
Xu Tianyu tried hard to recall when the Undead Orb in his consciousness suddenly trembled.
"Uh …"
Xu Tianyu was slightly stunned, then he took out the Undead Orb.
When he killed the Necromancer in Cloudsea City, he obtained the Undead Book and Undead Orb. He threw them into his consciousness and hadn't studied them yet.
He didn't expect that they would come out on their own now.
After the Undead Orb came out, the bones on the ground suddenly emitted a black mist, which was then absorbed by the Undead Orb.
"Ding! The Undead Orb has absorbed the Undead Aura. Current charge is 2%."
"Undead Aura?"
Xu Tianyu looked at the burial ground with a little surprise.
"Is there a Necromancer in the swamp forest?"
This was Xu Tianyu's first thought, and it was also a thought that he was very sure of.
Although there was a certain chance of Undead Aura being formed when a large number of bones were piled up together.
But the burial ground in front of him didn't have a large number of Undead Auras. That meant that someone had set up an Undead Array here.
"Necromancers, why are you killing so many animals in the swamp forest?"
Xu Tianyu frowned even more. He had a feeling that it wasn't something good.
He continued to move forward. This time, there were more burial grounds. Basically, there would be one every few hundred meters.
And the Undead Orb in Xu Tianyu's hand had successfully charged 20% in just a short while.
Xu Tianyu suddenly hoped that there were more burial grounds here. That way, he would be able to charge the Undead Orb and open the Gates of Hell.
However, what he expected didn't happen because he met a human.
Xu Tianyu quietly hid in a big tree and observed the camp in front.
In the camp, there were many warriors wearing beige armor. In the middle of the camp, there was a flag.
The big yellow characters were very eye-catching.
"Huang Jiajun?"
Xu Tianyu muttered softly. He had heard Elder Bai mention this army before.
To the east of the Heavenly Dragon Empire, there is a desert empire called the Sand King Empire.
The uniforms of the Sand King Empire's army were exactly the same as this group of people.
"Why would the Sand King Empire's army appear in the swamp forest in the north?"
Xu Tianyu was a little confused, but he quickly found the Necromancer in the crowd.
The necromancers who wore black hoods and long robes were very eye-catching among the warriors in yellow armor.
This Necromancer was much younger than the one Xu Tianyu had killed before.
And his status in the Sand King Empire's army wasn't low. Wherever he went, the warriors would give way and respectfully greet him.
"Could it be that the Necromancers are working with the Sand King Empire?
Or maybe the Necromancers were nurtured by the Sand King Empire? "
Xu Tianyu suddenly had a bold guess.
Although the Necromancers' status in the continent wasn't like rats that everyone wanted to kill, their situation wasn't much better.
