Each of these very beautiful-looking spirit crystals contains at least one piece of mineral, and the lowest quality of these minerals is at the highest level.

Yang Ning saw stars in his eyes, and his heart was itchy, and he couldn't wait to put them all into the space ring.

"Oops, I'm the one to go. How hard is this spirit crystal? ”

In addition to being excited, Yang Ning swung his fist on a piece of spirit crystal, trying to smash this piece of spirit crystal and take a piece of polish-sized high-grade mineral material inside the spirit crystal. Unexpectedly, this punch, which was close to fifty percent of his strength, not only did not break a crack in the spirit crystal, but instead shook the fist so painfully that it shook it straight.

"Quack Quack ......"

Seeing this scene, the 'Golden Weasel' grinned, and Yang Ning's farewell scene could be seen here.

"Eh, that little gold, can you break these spirit crystals and put them a little bit inside, so that the spiritual energy we can absorb will be a little more abundant."

Yang Ning looked at the 'Golden Weasel with some embarrassment', shook his arm, and hurriedly made an excuse.

"Quack, quack......"

Knowing Yang Ning's thoughts, the 'Golden Weasel Devourer' didn't say a word, opened its big mouth that could not be devoured, and under Yang Ning's stunned expression, it quickly ate a large hole one person high on the spirit crystal stone wall.

Those spirit crystals or minerals that were eaten into the stomach quickly turned into a rich energy that could improve the promotion of the 'Golden Weasel Weasel'.

Even though the 'Golden Weasel' could bite these spirit crystals and the minerals inside the spirit crystals, these spirit objects were too hard, and it took half a day for the 'Golden Weasel' to eat fifty meters deep.

"Uncle Yang, come here, this spirit crystal is too hard, I really can't bite it anymore, I can only get to this position."

The voice of the 'Golden Weasel' sounded in Yang Ning's heart, and it woke him up from surprise.

"Oh, oh, oh. I'll come over here. ”

"I'll go, it's a good mouth! It's so hard to gnaw such a big hole, cow! ”

Yang Ning, who woke up in shock, quickly ran towards the 'Golden Weasel', and couldn't help but admire the teeth of the 'Golden Weasel'.

Coming to the small cave opened up by the 'Golden Weasel Eater', the spiritual energy and the mysterious energy here were as thick as a swamp, Yang Ning felt that the pores all over his body were stretched, and he greedily devoured these energies without running the exercises.

"Little Kim, come to me and meditate. I'm going to get started. ”

Energy poured into his body, and Yang Ning felt that the small world in the dantian began to grow, and his strength increased again. This feeling that made Yang Ning's bones all over his body explode and intoxicated, made him can't wait to sit down cross-legged, and ordered the 'Golden Devouring Weasel' to lean on his side, wanting to devour the energy here as soon as possible.

In order to help Yang Ning open up this small cave to refine energy, the 'Golden Weasel Eater' had devoured too many spirit crystals and high-grade minerals in this small half of the day, filling its stomach, and it could even be said that it had eaten up.

The energy contained in these things is too pure, it is difficult to refine them all in a short period of time, after hearing Yang Ning's instructions, the 'Golden Weasel' hurriedly walked to Yang Ning's side, it wanted to use the energy brought by Yang Ning's exercises to accelerate the refining of those spirit crystals and minerals that were eaten in the stomach.

With the operation of the Mixed Spirit Devouring Technique, thick energy poured into Yang Ning's body like a tidal wave. The energy here was a hundred or a thousand times thicker than the place where he first entered the vein, and the effect obtained was also a thousand times greater. The small world in the dantian, under the infusion of these energies, expanded rapidly.

After running the exercises, Yang Ning closed his eyes, shielded all distracting thoughts, and the whole person became desireless and thoughtless, immersed in cultivation. The 'Golden Weasel' beside him also closed his eyes tightly, recklessly absorbing the energy gathered by Yang Ning.

Time passed slowly like this, a month passed, and the spirit crystals and minerals that the 'Golden Weasel Devourer' ate into its stomach were all refined into spiritual energy by it, and all of them were absorbed, and its breath was much stronger, and it was already close to the edge of the Venerable Beast.

However, the energy gathered here has not diminished in the slightest. Because of the spirit crystal in the stomach of the refining 'Golden Weasel', the 'Golden Weasel no longer needs to be distracted, and the speed of devouring energy has accelerated.

Yang Ning didn't change at all, and the thick energy was still pouring into his body, as if his body was like a dry sea, and no matter how much he couldn't pour it.

During this month, there have been some incredible changes in the veins.

With Yang Ninghe; The 'Golden Weasel' cultivated at the core of the ore vein, and the energy in the soil and rocks on the periphery of the ore vein seemed to be sucked away by something, and a trace of it flowed backwards to the core, and even the spiritual energy contained in the mineral material that had been formed was sucked away.

The group of miners who had been digging day and night in the passage gradually felt that the very hard rocks that had been blocked in the passage before were slowly becoming less hard, and when they were digging, they no longer had to work so hard and hard, and the progress of the excavation was nearly doubled.

"Good! Good! Good! Hahaha...... In this way, it is almost close to the vein. At this rate, the passage will be dug in less than a month. ”

After receiving the miner's report, Chen Haiping laughed happily, and the decline of many days was swept away.

The progress of the excavation of the passage is getting better day by day, and the more you dig in, the easier it is to dig the rock and soil. But they never imagined in their lives that the reason why they could do this was thanks to Yang Ning's contributions.

Chen Haiping was happy, but Yang Ning was even happier! In this month's cultivation, the small world in the dantian has expanded a lot, and now it is almost within a radius of ninety miles, much faster than he expected.

In a hurry, another half a month passed, and Yang Ning's cultivation reached the most critical moment. The small world in the dantian has expanded to ninety-nine points and nine miles, and it is only a trace away from reaching a radius of one hundred miles.

Yang Ning felt very genuinely that as long as the small world in the dantian reached a radius of 100 miles, then his realm would definitely break through to the supreme level.

But this slight gap seemed to be a Vajra gate that was a hundred times harder than the core spirit crystal of the ore vein, no matter how hard he tried, he couldn't pry open a crack in the door.

"That's it! It's done! Dig through the channel! ”

On this day, at the passage, the miners erupted in a wild shout. The clogged passage was dug out of a man-wide hole, protesting the faint glimpse of something inside the vein.

When Chen Haiping received the news, he rushed to the ore vein passage as soon as possible, looking at the newly dug passage, and his mood was indescribably excited.

It's finally time to get through the hardest days, and the years to come can finally live a little stable for the time being.

Excited, Chen Haiping took Gu Feng and Lao Xiaosong, and his figure flashed rapidly, crossed the gap dug up, and rushed into the ore vein. Here, it is no longer the periphery of the previous ore vein excavation, but has entered the inside, almost reaching the innermost part of the ore vein before it collapsed.

"Damn, those bastards of the Ruijin Sect are so ruthless that they almost collapsed the entire ore vein! Fortunately, fortunately, it didn't collapse, and the ore is still ......"

Taking a closer look at the situation around the ore vein, there was a little bit of crystal light flashing on the rock wall, Chen Haiping was excited, but also a little afraid, and kept muttering in his mouth.

"Bastard! What's going on? Who did this! Who the hell can tell me what the hell is going on? ”

The next moment, Chen Haiping, who had dug out a piece of mineral material from the rock wall in his hand, suddenly screamed like a convulsion. The piece of ore in his hand, although it shimmered with spiritual light, could be pinched lightly, and the ore was like an ordinary clay, turning into a cloud of mud and sand scattered from his fingers to the ground.

Gu Feng and Lao Xiaosong's faces changed drastically, and their figures jumped up sharply, each digging out several pieces of mineral material from the rock wall. The results made their faces look like ashes, and each piece of mineral material seemed to have completely lost all energy, and under a pinch, it turned into an ordinary mass of sediment that could no longer be ordinary.

For a moment, the three of them all felt cold hands and feet, standing in place stupidly, at a loss, and the clothes on their bodies were soaked with cold sweat at some point.

At this moment, two high-grade auras erupted in the core of the ore vein. One belongs to the monk, the other to the spirit animal.
