Isa carefully snuck back to the sinkhole.
She didn't directly return to the headquarters.
Instead, she pretended to walk in another direction.
After walking for a long time, she changed her direction again.
After going back and forth for two days, she found that no one was following her.
Only then did she come to the edge of the sinkhole and jump down.
Not long after, Zhang Xing, who was wearing the ghost cloak, also jumped down.
"Women really are strange creatures, she seems to be able to sense something"
"This is probably their headquarters," Ye Zichen said.
"They really know how to find a place"
While thinking, he also paid attention to his surroundings.
After flying down for about half an hour, he could faintly see some spike-like peaks.
But he still couldn't sense the location of the underground.
And Isa, who he was following, was still descending.
A cold wind kept blowing around him, it was bone-piercing cold.
The aura in the black fog also made him feel dizzy.
And, the further down he went, the stronger the feeling became.
Even Zhang Xing had to circulate his Draconic Qi to resist the corrosion of the cold aura.
"No wonder they chose this place as their headquarters, if you aren't at least a Saint, you probably won't be able to enter"
After another hour or so, Yisha stopped at the foot of a mountain in his spiritual sense.
Then she disappeared from Zhang Xing's senses.
A few minutes later, Zhang Xing found a hidden formation and quietly went in.
It felt like a cave was dug halfway up the mountain.
The passage was filled with formations and mechanisms, extending all the way down.
These formations and mechanisms were nothing to Zhang Xing.
He easily walked through.
Right now, Zhang Xing didn't dare to use his inner sight to search, afraid that he would expose himself.
Fortunately, he had the ghost cloak, otherwise, he might have been discovered by an unknown ghost.
That's right, other than formations, the Necromancer Saints also set up a large number of ghost patrols.
Ghosts were also part of the undead race, they were ranked higher than zombies.
In other words, they were the remnant souls of humans or demonic beasts.
But the Necromancer Saints rarely used them in battle.
Their purpose was only to be used as nutrients to be absorbed.
The Necromancer Saints needed a large number of ghosts to cultivate.
The staff that Zhang Xing took from Ling Luo stored a large number of ghosts.
He hadn't decided what to do with them.
However, he did not intend to let Dark Knight Mo Li devour it.
After walking for another four hours, they finally reached the end of the long and narrow passage.
The layout in front of him changed, and it immediately became wider.
However, looking at the massive palace made of bones before him, Zhang Xing was still shocked.
Among these bones, there were basically no human bones.
Almost all of them were skeletons of magical beasts of the tenth grade and above.
Some were leg bones, some were skull bones, and some were sternum bones.
However, none of the skeletons he had seen were complete.
It was obvious that these were the remains of ancient beasts that had died in the great war a thousand years ago.
The palace gate was made up of the heads of eighteen black dragons.
Yisha's figure was walking inside.
Zhang Xing stayed outside and did not enter rashly.
At this moment, there were already dozens of Necromancer Saints gathered in the palace.
They were all sitting on the wide chairs made of bones, and they were all silent.
"Isa, what's the situation outside?"
A bone-like old man sitting at the head of the table asked in a hoarse voice.
"President Ghost Tyrant, we haven't found any traces of that young man yet."
"He's probably commanding his undead army to destroy the rest of our zombie army."
Isa sat at the last seat at the end and let out a long sigh.
