Millions of ghosts gathered together, even if they were just spreading unconsciously, with such a huge number and such a long period of accumulation, it is absolutely possible that soul crystals could grow inside the mountain.
"Let's go and take a look now!" Li Ziyu made a prompt decision and decided to enter the mountain to look for the crystal emitting a hazy light from Fox Princess's mouth.
Taking the fox princesses, they re-entered the interior of the Ghost Mountains through the passage where the undead transported bones. Along the way, the fox princesses were quite emotional. It was here that they were trapped. They had lived here for countless years, and since they left, they never thought of coming back.
Entering the innermost space, even though the undead were transporting the bones non-stop, the number of bones inside did not decrease much and was still piled up like a mountain. Seeing so many bones, Li Ziyu couldn't help but smile.
For others, mountains of gold and silver are treasures, but for him, these bones are the real mountains of gold and silver. No, he would not exchange them even if he was given mountains of gold and silver!
"What should we do next?" Li Ziyu looked up at the piles of bones, then turned to look at the four fox princesses behind him.
"Master, don't be anxious. We haven't been back for a long time. Let us first determine our location." Mei Ji said coquettishly and gave Bing Ji a look.
Bing Ji immediately drilled into the Skeleton Mountain and disappeared. They were all in spirit form, and neither the Bone Mountain nor the Soul Mountain's soil could stop them.
After a long while, Bing Ji finally emerged from the Bone Mountain and returned to Li Ziyu.
"Have you found it?" Li Ziyu hurried forward and asked.
"Found it. They are everywhere around, and there are more of them over there." Bing Ji pointed to a place and said to Li Ziyu.
Nothing much to say, dig!
Li Ziyu summoned a dozen skeleton undead and asked them to dig inside in the direction of Bing Ji's finger.
A dozen skeleton undeads walked forward silently and began to dig, but there were too many bones in front of them. After digging for a long time, they didn't make much progress. There were too many bones, like a wall blocking them. Moreover, if they continued like this, there was a risk of the piled bones collapsing.
Li Ziyu thought about it and summoned more skeleton undead, asking them to work together. Not only did they have to dig out a passage, but they also had to provide some support to prevent the mountain of bones from collapsing.
Outside this cave, there is a thick layer of soil. If the support is lost and the cave collapses, it will be a big trouble.
With help, the skeleton undead increased their speed. While digging inwards, they stood the bones upright to support the surrounding bones, and gradually formed a mine-like passage on the bone mountain, leading directly to the mountain.
After digging for two hours, a skeleton undead came to report that they had reached the soil layer. Li Ziyu asked Bing Ji to go in and guide the skeleton undead on the next digging route.
Bing Ji nodded and floated into the mine.
Li Ziyu was waiting anxiously outside. Not long after, Bing Ji floated out, followed by a skeleton undead. They walked through the bone mountain with one step deep and one step shallow, and came in front of Li Ziyu.
"Have you found it?" Li Ziyu asked hurriedly.
"I have accomplished my mission." Bing Ji nodded and motioned the skeleton undead to come forward.
The skeleton undead staggered over and spread out his palm in front of Li Ziyu. In his hand was a palm-sized prism-shaped crystal, which he showed to Li Ziyu.
