The miner's fur was a little gray, and Han Yu was startled and hurriedly used the Heavenly Eye Technique to check it, only to find that the spiritual power was gathering in the middle of the waterhole like silk threads.

"Is this mine rat going to break through?"

Han Yu faintly felt the truth, and felt slightly bitter in his heart, he thought that he was hiding some treasure, but he didn't expect that this group of mine rats was guarding!

The mine rat sensed the movement, opened his eyes, and saw the strange human appearing, and immediately "squeaked", and the sound spread rapidly along the mine!

The miners, who were struggling to resist this, suddenly found that the miners had given up attacking humans and retreated like a tide.

"Rush up!" Xing Yuan's face sank, and he hurriedly said.

But the speed of human beings can not be compared with that of rats, and a group of people chased after them without even seeing a single mouse hair.

Xing Yuan's face suddenly became a little ugly, and he quickly gathered more than a dozen elite subordinates to pursue along the entrance of the cave, wanting to pick up Han Yu over.

Han Yu's ears were pressed against the stone wall, and he could faintly hear some noises, knowing that this mine rat was gathering his companions.

The only spell he learned was the fireball technique, but he didn't know if a small fireball could kill this mine rat!

And that fireball spell consumes a lot of mana, so if it doesn't hurt the miner rat and provokes it, it won't be good!

After a while, he saw a group of mining rats rushing over, Han Yu gritted his teeth, slapped a golden talisman in his hand on his body, and suddenly a phantom of a golden shield appeared on his body.

The mine rat slammed into it, the golden shield did not move, Han Yu's heart finally settled down a little, and he pondered a way to escape.

"Squeak.."

At this moment, the miner rat sitting on the stone platform let out a cry of pain, and his gray hair was slowly turning black from the tail, spreading towards the rat's body.

"Progressing!"

Han Yu knew that this was a mine rat that was advancing from an ordinary demon beast to a first-order demon beast, and as long as it evolved successfully, it could be comparable to a qi refining cultivator.

When the jet black spread to the neck of the mine rat, the spiritual power on this waterhole had become thin, and when I saw the mine rat scream miserably, the black skin slowly degenerated, and the color of the retreating fur turned into a miserable gray!

The monster beast would die if it failed to advance, and the group of miners heard the leader's wail and slammed into the golden shield desperately.

Han Yu's heart also became extremely anxious, if this demon beast failed to evolve, he would definitely be swallowed alive by this group of mining rats, and there was no reason to be spared!

Han Yu hesitated slightly, took out a low-rank spirit stone from the storage bag, and threw it towards the giant rat!

"Squeak!"

Seeing that the object thrown by the human contained aura, the giant mad rat caught it with its claws like a human, gnawed it with its giant teeth, and swallowed it directly into its stomach.

The degradation of the black hair was temporarily suppressed, but after a few breaths, it began to slowly recede again, and Han Yu threw another one when he saw this!

"Squeak!"

The giant rat was overjoyed, happily took the spirit stone and swallowed it into his abdomen, ordering the ordinary mad rat not to continue attacking, and Han Yu's pressure suddenly lightened.

I saw that one by one the spirit stones were thrown out by Han Yu, and the black hair gradually covered the neck and began to emerge on the head, as long as the whole body was covered with black hair, the giant rat could advance!

All the low-rank spirit stones in Han Yu's storage bag were thrown out, and blood was dripping from his heart, but a small area of black hair on the giant rat's forehead did not grow.

In desperation, Han Yu tried to throw a rough stone, but the giant rat directly caught it and threw it into the water, looking at Han Yu longingly.

Han Yu scolded angrily in his heart, but he still obediently took out an intermediate spirit stone from the storage bag and threw it over reluctantly.

The giant rat took it and swallowed it directly into its abdomen, and all the black hairs on its forehead grew.

"Squeak!"

The giant rat screamed, and suddenly the spiritual power in the mine cave converged towards it, only to see the giant rat shed a layer of skin, sharp claws, and five-inch long giant teeth grew out, only to see him try to gnaw on the stone platform, but the hard stone was like tofu!

Advanced Success!

Han Yu witnessed the giant rat evolve into a demon beast, but he was a little uneasy in his heart, this mine rat could easily bite him to death.

The mine rat jumped into the waterhole and swam in front of Han Yu, who looked at the shiny miner with shiny hair and thought that he wouldn't be the morning tomorrow!

"Squeak.."

The mine rat didn't attack, but instead circled around Han Yu, his eyes still revealing longing.

"It's gone!" Han Yu said helplessly.

He didn't know if the mine rat could understand human language, but he had to try. This has just consumed a lot of spiritual power for it to advance, so it won't turn its face and deny people!

The mine rat threw out a longing cry, and Han Yu could only take out another intermediate spirit stone and throw it over, but the mine rat didn't take it and let the spirit stone roll down.

"Don't you want spirit stones?" Seeing this, Han Yu poured out all the contents of the storage bag, only to see the mine rat making a "squeaking" sound towards several pieces of red ore.

This person was under the rat eaves, and had to bow his head, Han Yu threw the few pieces of unknown ore over, and was directly swallowed by the mine rat.

"Hey, can you let me go?" Han Yu asked dryly when he saw the anthropomorphic satisfaction on the mouse's face.

Seeing that the mining rats screamed, the group of ordinary mining rats disappeared in the blink of an eye, and Han Yu breathed a sigh of relief in his heart.

Although the spirit stones in the bag are gone, and the ore is gone, my life is still there, and I am not afraid to start all over again!

Han Yu arched his hand towards the mine rat and was about to leave, but saw that the mine rat's four paws were stretched out, and the rat's head also clicked on the ground a few times, as if he was thanking Han Yu.

Han Yugan laughed a few times, left in a hurry, climbed halfway along the narrow mine, and met Xing Yuan and the others who came to look for him.

Han Yu waved his hand, and the few people reluctantly turned around in the passage and crawled towards the exit.

The group tossed and turned their faces, returned to the stalactite cave Han Yu inquired about the casualties, and learned that dozens of people were killed and injured and were silent, and asked Xingyuan to give the injured brother a good recuperation.

Han Yu returned to the hut and found that the tossing back and forth was almost the end of the day, so he simply didn't sleep, and went to deal with the spirit debris after resting for a while.

When he was done, Han Yu lay directly on the bed and slept in the dark, and didn't wake up until the end of the day, touching the shriveled storage bag, and his heart ached.

Han Yu had to swallow the pill every day and hold the spirit stone in his hand to cultivate, which was very effective, but now that there were only two spirit stones left, Han Yu couldn't bear to do anything.

"Alas!" Han Yu sighed heavily, sitting on the stone bed racking his brains in exchange for spirit stones.

The chain of interests must not be deducted, if you give more, they don't care, if you give less, you will definitely hold a grudge.

The idea of killing people and snatching treasures flashed in his mind, he was still a far away among the weak, and the things on his body were all protective, so it would be good not to be robbed!

"I can only save it slowly!" Han Yu knocked his head with a headache, he could get dozens of spirit stones from the profit distribution every month. Of course, everyone else thinks that there are only three or four at most.

Since last night, when the water and rice have not been entered, Han Yu came to the ground to eat in the restaurant, and returned to the underground without pausing.

Han Yu was planning in his mind how to deal with Yin Qiuping, it was not difficult to deal with him, but the difficult thing was how to be quiet, there was a foundation building monk standing behind him, and Han Yu couldn't afford to mess with him.

As for the old man surnamed Tai, Han Yu pondered in his heart from time to time, this old man was half-cut into the earth and had no hope of building a foundation, why did he still have to make money like crazy, and he couldn't even take care of his face?

After swallowing the pill and practicing silently, his speed slowed down a few points without the assistance of spirit stones, which made Han Yu very uncomfortable.

At night, Han Yu was a little impetuous and went to the cave where he practiced martial arts, practicing martial arts without distractions, and when he finished practicing, he found that a mine rat ran over, squeaked at him, and then stopped at a certain hole.

Han Yu was startled, but his footsteps followed, the advanced mine rat should not be looking for trouble afterwards if he let him go.

The mine rat took Han Yu to move forward in the maze of caves, and some of the holes couldn't be drilled into at all, so Han Yu took out a mine pickaxe from the storage bag and pried it open, and crawled with the mine rat.

After crawling for about two hours, Han Yu was out of breath when he was tired, took out water from the storage bag, poured a sip, rested for a while and continued to crawl.

After another half an hour, the mine rat took him to the depths of the spirit mine, Han Yu unbelievably touched the raw ore on the wall, these were actually medium-grade rough stones!

Han Yu followed the mine rat to a small grotto, the mad rat that had just advanced was tearing the rough stone with its teeth, and a few intermediate spirit stones full of tooth marks were scattered around it, Han Yu was distressed to see it.

"Squeak!"

The mine rat saw Han Yu scream, and Han Yu noticed that there were faint traces of fiery red in his black hair, and he didn't know if it was because he had swallowed the mineral food.

The mine rat took a few biting spirit stones from the ground and threw them to Han Yu. Han Yu didn't expect it to repay the favor, and the remuneration was actually a medium-grade spirit stone!

Han Yu's careful thought in his heart that he wanted the miners to come here to dig was suddenly extinguished, although these medium-grade spirit stones were pitted, they could be used for cultivation.

Han Yu also accepted the spirit stone unceremoniously, and the mine rat was also very happy, Han Yu suddenly remembered something, picked up a medium-grade rough stone and asked, "Is there a rough stone with stronger spiritual power than the spiritual power?"

The mine rat screamed, threw down the half-gnawed rough stone, and led Han Yu to a narrower passage next to him, and continued to walk underground.

After climbing for another hour, the mine rat took Han Yu to a mine wall, only to see that it was a whole piece of rough stone, exuding a rich aura!

Han Yu was overjoyed in his heart, and kept touching back and forth, if he cultivated here, he would definitely have a lot of benefits, and he would soon be able to break through.

But it's a pity, Han Yu has a lot of things to do every day, and it takes a full three and a half hours to come here, and now he can climb back just in time to clean up the spirit debris.

"Spirit crumbs?" A vague thought suddenly appeared in Han Yu's mind, wanting to grasp the inspiration that had just flashed away.

"Fountain of Spiritual Eyes!"

Han Yu learned from the black ancient books that putting the spiritual eye fountain into a place with abundant spiritual energy can return to its original appearance, although the daily spiritual crumbs can be nourished, it is always unsafe to put it there, if it is placed here, it will be difficult to find the immortals.
