The entrance to the mine was extremely wide, and the entire passage was sloping down to the ground, and the magic crystal lamp that was originally used for lighting was destroyed by the Devouring Beast, and Bai Ling's light magic came in handy.

The mine is littered with mining carts and pickaxes, as well as refined iron ore that has not been transported out in time. Along the way, I saw a lot of miners who were killed by the Elemental Devouring Beast, apparently they didn't have time to withdraw from the mine, and were attacked by the sudden appearance of the Elemental Devouring Beast.

Fortunately, the Yuan-devouring beast fed on the Yuanli Stone, and the miner's body was still relatively intact, and the scene was not particularly bloody. Rao is like this, Bai Ling's little face is a little pale.

"Brother, these people are so pitiful,,,"

"Hey, these people are also part of our Niu family, and I can't bear to suffer this kind of hardship suddenly. Don't worry, Ling'er, when we settle the matter here, I will send someone to take care of their small family. ”

The shining crystal that had been moving forward suddenly stopped, and snorted at the darkness ahead.

"Hmm? Niu Fei sensed it with his spiritual power, rubbed a blazing fireball in his hand, and threw it towards the front road. Two shadows flickered. "On both sides of the mountain wall!"

Bai Ling's spear of light shot out in response, shooting straight into the mountain walls on both sides, blocking the path of the two elemental devouring beasts.

The enraged Yuandevouring Beast opened its mouth and pounced, "It's a good time!" Niu Fei took out the jade bottle, and his battle qi surged, and he raised his hand to throw out two drops of camphor grass liquid until it fell into the beast's mouth.

The two elemental devourers smashed to the ground and began their journey to self-exaltation.

"Two third-level primary-level primary-devouring beasts, it seems that there are really a lot of primordial devouring beasts in this mine. There may be more powerful Elemental Devouring Beasts in the back, all of which are mounts. Looking at the surrounding forks in the road, this has to be explored, not to mention that you can get together a hundred horses, Niu Fei's heart is hot.

"Brother, you're drooling! With so many intersections, how are we going?"

"Well, yes, maybe it's hot in the mine, it's sweat. Niu Fei wiped the corners of his mouth, "Let's go to the deepest part of the main road, and those miners outside say that the Yuandevouring Beast is pouring out from the deepest part." ”

"Ling'er, are you ready?"

"Ready? Ready. Bai Ling nodded puzzled.

"Shiningjing, hurry up! Let's have a group brush. Niu Fei gave an order, and Shanjing rushed directly forward with the two of them.

Bai Ling exclaimed, his body leaned back suddenly, and the magic used for lighting in his hand was almost extinguished, but fortunately, there was Niu Fei behind him, so he stabilized.

Although the Ice Crystal Dragon Horse is a flying demonic beast, its running speed is also extraordinary, not to mention a king beast like Shiningjing.

The second-level elemental devouring beasts encountered along the way were all thrown off, and only the third-level primordial devouring beasts could barely keep up, and it was not until the bottom of the mine, in front of a pit with a diameter of nearly two meters, that the shining crystal stopped.

It's not that Shinjing doesn't want to go over, it's just that there is a fourth-level strength Yuan Devouring Beast squatting in front of this hole, and its huge body is blocking most of the hole, staring at the two of them.

"Brother, what should I do now, this big guy in front of me seems to be very strong. ”

"This ,,," fourth-level Elemental Devouring Beast, this is already an intermediate-level Demonic Beast, and Niu Fei is not sure if the camphor grass liquid has any effect.

"Can't wait, try first. The sound of breaking the air behind him invisibly gave Niu Fei great pressure, and twenty or thirty third-level Yuan Devouring Beasts chased after him, the road ahead was really blocked, and there were chasing soldiers behind.

Niu Fei took out a piece of Yuan Li Stone from the ring, smeared the camphor grass liquid on it, and threw it towards the Yuan Devouring Beast blocking the road. The Yuanli Stone smashed on the ground two feet away from the entrance of the cave, and the Yuan-devouring beast sniffed the smell of temptation and fidgeted.

But as if he had a duty, he neither ate the Yuan Li Stone nor killed Niu Fei and his party, so he firmly guarded the entrance.

There is a play! Camphor grass liquid still has an effect on the intermediate Yuan Devourer. Niu Fei hurriedly took out nearly a hundred Yuan Li stones, piled them on the ground, added a few drops of camphor grass liquid, and threw them in front of the entrance with battle qi.

The Yuanli Stone was originally the only food for the Yuan-devouring beast, and coupled with the unique smell of camphor grass liquid, the saliva of the Yuan-devouring beast squatting and guarding it flowed sideways. In the end, instinct prevailed over reason, and the Yuanli Beast pounced on the Yuanli Stone Pile.

"It's now!" Niu Fei slapped the flash crystal and rushed towards the entrance. The fourth-level Yuan Devouring Beast had just swallowed a few Yuan Force Stones, and hurriedly turned around to intercept it, but the effect of the medicine was stimulated a beat slower.

After Shining Crystal rushed into the entrance, the Yuan-devouring beast guarding the door came to the entrance, its huge body lying prone at the entrance, its eyes glazed and its saliva flowing.

Niu Fei wiped his sweat, looked sideways at the entrance of the cave and said, "God help me, this fourth-level Yuan-devouring beast just blocked the entrance, and we don't even have to deal with those third-level pursuers." ”

Bai Ling turned his head to the other side, as if he hadn't heard Niu Fei's words, his eyes lit up, and he said to himself: "Brother,,, brother, look, this is not a dream!"

Niu Fei turned his head and froze instantly, "It's really a Yuanshi vein, you've made a fortune, you've made a fortune!" Niu Fei's blood surged, and his face turned red.

As far as the eye can see, the walls of the cave, including the ground under your feet, reveal crystal-like Yuanli stones in the rocks, which reflect white pieces of brilliance under the illumination of the white spiritual light magic.

"Something is wrong, isn't that?" Niu Fei suppressed the excitement in his heart and said suddenly.

"What's wrong, what's wrong, it's all Yuanli Stone. Bai Ling was puzzled.

"Ling'er, you don't know anything. Yuanli stone is divided into upper, middle and lower three grades, a top grade can be exchanged for a hundred lower grades, we used to use lower grade Yuan Li stone. ”

Niu Fei jumped off the horse, took out a piece of Yuan Force Stone from the ring, and picked up a fist-sized crystal and compared: "According to the Yuan Devouring Beast we encountered, this vein is only of medium grade at most, how can there be so many high-grade Yuan Force Stones?"

Bai Ling also jumped down, looked at the Yuanli Stone in Niu Fei's hand, and took it over to feel it carefully, "It's really different, the purity of the Yuanli Stone here is so high." ”

"Let's be careful, there's something weird about this place. Ling'er, you follow me. Niu Fei took Bai Ling's hand and walked forward.

It is said that the cave should be a paradise for the Yuan Devouring Beast, but Niu Fei didn't find any of them, and as he gradually went deeper into the cave, the grade and purity of the Yuan Li Stone gradually improved.

At the end of the cave, on the steps slightly above the ground in the cave, only one person was allowed to pass, Niu Fei probed his brain and took a look, and immediately retracted like an electric shock.

"Brother,,," Bai Ling was just about to speak, Niu Fei covered her mouth, shook his fingers slightly, pulled Bai Ling quietly down the steps, and retreated a few feet, as if he was afraid of alarming something.

Bai Ling broke Niu Fei's palm, "Brother, how is it? what's in it?"

Niu Fei wiped the cold sweat from his forehead, "A big worm, at least three times bigger than the fourth-level Yuan-devouring beast we encountered just now, at least, I estimate that this Yuan-devouring beast should be level five." ”

"Isn't that equivalent to a swordsman or magician-level powerhouse? What should I do, why don't we quit first, and wait for the old lady to break through, and then come to encircle and suppress this Yuan-devouring beast." Bai Ling's face was also a little pale, the fifth-level demonic beasts were far from what their second- or third-level strength could handle.

"I don't know how long it will take, but I just looked at it, this big guy should be asleep, and his perception is not strong, so he didn't notice me. There's still some camphor sap, feed it down, we'll have a chance. Niu Fei said in a deep voice.
