"What escaped?" Zhang Yu was taken aback, his feelings were in vain for a while?

The ghost mother actually fled, he looked around with the eyes of the ghost god, and sure enough, he saw a cloud of black gas disappearing in the distance.

Zhang Yu wanted to catch up, but suddenly felt that the dantian was empty, and he had no choice but to lift the combined state.

"Forget it, spare it once this time. Zhang Yu sighed and said, letting go of the ghost mother like this will definitely have endless troubles, but unfortunately there is no way.

The ghost mother fled, and so did the runaway rat colony, after all, this is the territory of monitor lizards, and the smell of monitor lizards is everywhere.

The rats are underground scavengers, they can eat anything as long as they can fill their stomachs, and when they leave, the corpses are dragged away.

If it weren't for the bloodstains on the ground and the strong smell of blood in the air, it would have been as if nothing had happened here, and the badly injured monitor lizard was lying in place, motionless, Zhang Yu thought it was dead, and walked over only to find that this guy was still moving.

"It's a pity, what a body!" Xiao Hei sighed as he stepped onto the demon monitor lizard's body. Zhang Yu looked at it with the eyes of ghosts and gods, and found that the monitor lizard's brain was damaged by the ghost mother's black gas filament, and it seemed that he would not live long.

Zhang Yu followed Xiao Hei to the top of its head, only to see that the monitor lizard's big eyes were half-opened, full of sadness, it glanced at Zhang Yu, and closed its eyes again.

"I'll give you a good time!" Feeling its pain, Zhang Yu pulled out the Nine Heavens Xuan Sword. It's a pity that before Zhang Yu made a move, the monitor lizard was already dead, Zhang Yu shook his head and put away his long sword.

"Die, quick, it has a crystal nucleus in its body. Xiao Hei sniffed excitedly in the east and smelled in the west.

"Crystal nucleus, is it?" Zhang Yu remembered the life-and-death upgrade options in the system.

"Yes, yes, I'll see where its crystal nucleus is......" Xiao Hei said as he sniffed everywhere. Zhang Yu smiled slightly, and when he looked over with the eyes of the ghosts and gods, he could see a white ball of light flickering on his head.

"That's ......it," Xiao Hei ran there, and he patted the monitor lizard's head somewhere with its paws and said, it happened to be in the same position as Zhang Yu saw.

"You've got a good nose. Zhang Yu praised, and Xiao Hei wagged his tail proudly.

"It's like a dog......" Lin Xueyue, who was holding a war knife next to her, teased, her little black ears and tail hung down all of a sudden, and she looked at Lin Xueyue sadly.

Zhang Yu took out the Nine Heavens Xuan Sword and stabbed it down with a sword, probably because the monitor lizard had died, and its scale armor became very fragile.

Zhang Yu was busy for a while, and sure enough, he dug out a golden crystal from its skull, which was octagonal. As soon as he grabbed the crystal in his hand, the system in his mind immediately prompted: "Found a crystal nucleus, whether to absorb it!"

Zhang Yu was stunned, he also took the initiative to absorb it for the first time, the last time he absorbed the fire crystal caused the system to be upgraded, the ghost mother has not been killed, if the system is upgraded, it will be embarrassing.

Zhang Yu canceled the absorption line selection and put away the crystal. The corpse of the demon monitor lizard is also a good thing, and Zhang Yu collected some of its claws and teeth at Xiao Hei's prompting.

"Huh, what is this?" Lin Xueyue lowered her head as if she saw something, she flew over, and under Zhang Yu's curious gaze, she took out a white crystal from the rubble ruins.

"What did you find?" Zhang Yu walked over curiously.

"It seems to be a spirit stone?" Lin Xueyue looked at it and said uncertainly, she handed over the white crystal, Zhang Yu took it out and looked at it, this is not a spirit stone, and the grade of the spirit stone is relatively high, and an idea appeared in Zhang Yu's mind in an instant.

Could it be that there are spirit stone veins here? Zhang Yu became short of breath.

"Let's look around and see if we can find something?" Maybe there is a vein of spirit stone here...... "Zhang Yu shouted excitedly.

Xiao Hei and Lin Xueyue glanced at each other, and their hearts became excited, and they hurriedly scattered to look for each other.

It's a pity that after looking around, they didn't find any trace of other spirit stones, so where did this spirit stone come from? Zhang Yu returned to the place where Lin Xueyue found the spirit stone again, and looked at it carefully.

Zhang Yu switched the eyes of the ghosts and gods and looked around, but unfortunately he didn't see anything.

"Do you want us to go to the monitor lizard's lair and have a look?" Lin Xueyue suddenly thought of something and proposed.

"That's a good idea!" Xiao Hei nodded, Zhang Yu patted his head, how could he forget the monitor lizard's lair, and they hurriedly set off to fly towards the monitor lizard's lair.

The monitor lizard's lair was littered with bones and debris, and a peculiar stench emanated from it, which was like an enclosure sign, and many other creatures were afraid to come here.

Zhang Yu held his breath, searched everywhere, and soon found a huge cave in the waste, Zhang Yu asked Xiao Hei to go in first to explore the way, and he took Lin Xueyue around and found several huge skeletons, Zhang Yu flew around the skeleton and found that this skeleton should be left by some kind of huge creature.

The skeleton is covered in bite marks, and it is possible to imagine the creature being preyed upon by demonic monitor lizards and then gnawed away.

"A lot, a lot! Come and see ......" Suddenly Xiao Hei's excited voice came, Zhang Yu was overjoyed, and hurriedly flew over.

"That's a lot, a lot!" When Zhang Yu followed Xiao Hei's instructions and followed the winding road to the depths of the cave, he was also stunned by the scene in front of him, only to see that all the cave was full of spirit stone crystal clusters, and he was almost dazzled, Xiao Hei squatted on the ground and repeated dream-like repetition.

"It's so beautiful!" Lin Xueyue's eyes flashed, she covered her chest and sighed, a woman's head circuit is indeed different from a man's.

"Spirit Stone Vein!" Zhang Yu swallowed his saliva with difficulty, looked at this cave spirit stone and muttered, fortunately, the Heavenly Master clan advocated quiet and inaction, and he was the first to react.

"I want to eat, I want to eat, I want to eat enough!" Xiao Hei suddenly jumped up, rushed over and hugged a spirit stone crystal cluster and bit wildly.

Zhang Yu then remembered that although the spirit stone is the currency of this world, it is more used as a cultivation material, and it is common in the Three Realms, and in the later stage, many cultivators cultivate by absorbing spirit stones.

"Okay, okay, the spirit stones here are enough for you to eat!" Zhang Yu shook his head and walked over, grabbing the fur behind the little black head and said.

"Woo woo, it's the first time I've seen so many spirit stones, I'm so excited!" Xiao Hei saw Zhang Yu, and then he came to his senses, and he said with emotion.

"It's not promising!" Lin Xueyue said with disdain, her eyes lit up.

"Wow, this is so beautiful!" she picked up a good-looking spirit stone with her slender hand.

"As long as you think about absorbing it, the spirit stone will be absorbed into your body and increase your strength. Xiao Heizi seduced beside him.

"Really?" Lin Xueyue's hand paused slightly, and the spirit stone in her hand instantly melted and then flowed into her body, and the naked eye could see that her soul body was much clearer, like substance.

"Really, it's so comfortable!" Lin Xueyue said with a satisfied expression.

Xiao Hei wanted to tease a few words, but he sighed when he thought that he would be bullied.

It suddenly thought of something, turned its head to Zhang Yu with big watery eyes, and said, "Master, or we will occupy this spirit stone vein......
