A white jade ribbon with a soft glow struck the stone wall, winding into the depths of the cavern like a white python.

A rich aura emanated from the white jade belt, and the aura was almost a hundred times that of the outside.

This is the spiritual vein!

If you absorb all of them, you should be able to advance to the Jie Dan Realm, or even the Condensing Realm.

However, it was obviously impossible to advance to the Yudan Realm in two months just by absorbing the aura that was emitted.

And it is impossible for him to really absorb all the spiritual veins, otherwise there will likely be problems in the secret realm, and he will not be cut down by the people of the Yan family after he goes out.

However, it is obviously not cost-effective to spend two months refining spirit crystals.

After a little hesitation, Ling Zhen made a decision, half of the time was spent cultivating, and half of the time was spent refining spirit crystals.

As soon as he said it, Ling Zhen began to refine the spirit crystal.

Refining the spirit crystal is not complicated, using the "Extracting Spirit Seal" to extract the pure spiritual energy in the spirit vein, and then condense it into a pill, which is the spirit crystal.

Although it was not complicated, it was a time-consuming process, and with his cultivation in the middle of the foundation building realm, he could refine at most one spirit crystal in an hour.

A spirit seal quickly condensed from Ling Scar's palm, and then imprinted on the spirit vein.

Suddenly, a rich aura erupted from the location of the spirit seal and rushed towards Ling Zhen's palm.

At this time, the position of Ling Scar's palm seemed to have become a whirlpool, quickly devouring the gushing aura, forming a perfect channel.

To use the simplest analogy, the spiritual vein is a water pipe, the spiritual energy is the flow of water in it, and the palm of Ling Scar's hand is a well.

But this well has the function of compression, compressing the flow of water flowing into it to form a solid state, which indicates that the spirit crystal has been successfully refined and a spirit crystal has been obtained.

An hour passed.

As Ling Zhen had estimated, the spirit seal on the spirit vein had disappeared, and there was an extra spirit crystal in his hand.

Although it took an hour, looking at the spirit crystal in his hand, Ling Zhen still had a sense of accomplishment.

Immediately after that, Ling Zhen spent another two hours refining two spirit crystals.

I feel that the mana in the dantian has been almost consumed, and it takes a lot of mana to condense the "Soul Drawing Seal".

At the same time, the spirit also felt tired, and there was a feeling of drowsiness.

As a result, Ling Jian stopped refining the spirit crystal and began to cultivate against the stone wall.

......

Time passed day by day, and before I knew it, ten days passed.

In these ten days, Ling Zhen had refined a total of forty-eight spirit crystals, an average of about five per day.

The harvest can be said to be very rich, but the improvement in cultivation is not large!

Even if you rely on spiritual veins to cultivate, the mana condensed by daily cultivation is still limited.

According to the current progress, two months will definitely not be able to advance to the late stage of the foundation building realm, at least half a year.

This is not very satisfying for Ling Zhen!

What he wanted was to advance to the late stage of the Foundation Building Realm within two months.

After some mental struggle, Ling Zhen changed his previous plans.

He decided to use the spirit crystal to cultivate, the spirit crystal contained extremely pure spiritual energy, and the cultivation effect could be increased by almost ten times.

In this way, it took two months to completely advance to the late stage of the Foundation Building Realm and achieve the goal he wanted.

Of course, the disadvantage is that he has to consume the refined spirit crystals, and there is no excess spirit crystal storage.

Although this cultivation is improved, it cannot save the spirit crystal.

Compared with two by two, it is actually not cost-effective, and it is a bit like a monk hitting the clock for a day.

However, Ling Zhen still decided to do this, he needed to improve his cultivation first, and as for the subsequent cultivation, he would talk about it later.

So from the eleventh day, Ling Zhen spent half of his time refining spirit crystals and half of his time cultivating with spirit crystals.

But soon his plan was disrupted again, and every time he was refining the spirit crystal, when he was cultivating, the figure of a woman always appeared in his mind from time to time.

There are Xu Huaixue, Yan Zhen, Yang Mei, Bai Yige, and even some inexplicable and wonderful women, each of them is stunning, and the most important thing is that each of them is affectionate and affectionate towards him.

Like a moth to a fire, he surrounds him, the kind that can spend the clouds and rain with him at any time as long as he wants.

Needless to say, this is what Yan Zhen said about the magnified valley lack of hope!!

As the time spent in the secret realm was extended, this kind of valley hope became stronger and stronger, and these beauties were no longer willing to keep their pulse in a state with him, but became more and more presumptuous, taking advantage of him in various ways.

At the same time, they are also crossing less and less, whether they have their eyes closed or open, their minds are full of them.

It had already seriously affected his refining spirit crystals and cultivation.

It wasn't until this moment that Ling Zhen really understood why Yan Dan failed the last time Yan Zhen did.

Even if they know that it is an illusion, there are a few men who can remain calm and indifferent in this situation.

Every day was a torment for Ling Zhen, and it took a lot of time to suppress the illusions in his mind, not only did the number of refining spirit crystals decrease, but the time for cultivation naturally decreased.

And it's only been about 20 days!

It's really hard to help with this errand!!

Compared with Ling Zhen's torment, Yan Zhen in the Yin Yang Pool was much calmer, although she would also have illusions, but the degree was much lighter than Ling Zhen.

Time is still passing, and Ling Zhen is still holding on!

But more and more time was spent suppressing the illusion, and Ling Zhen couldn't think about whether he would be able to advance to the late stage of the Foundation Building Realm in two months.

He just wanted to end this torturous process quickly.

......

It's been a month.

Ling Zhen felt like he had lost a lot of weight.

In the cave, Ling Zhen had a big stone tied to his body, gritting his teeth and continuing to refine the spirit crystal.

Two hours later, a spirit crystal was successfully refined.

He couldn't wait to swallow the spirit crystal and cultivate.

"Ling Scar, save me ......"

"Ling Zhen, save my ......"

Recently, the illusions in his mind have become more and more intense, and they directly entangle him without hindrance.

The most ferocious one was Yan Zhen, who seemed to be trapped in the valley and couldn't extricate himself.

If you don't save her, you may be burned to death at any time.

And it's so real, as if it really happened.

It may be because Yan Zhen is closest to him, so this illusion is even stronger.

But Ling Zhen kept telling himself in his heart that this was an illusion, this was an illusion!

It's an illusion......

A few more days passed.

"Ling Zhen, save my ......"

"Ling Zhen, save my ......"

Ling Scar, who was cultivating, suddenly opened his eyes, his eyes were filled with madness, and he shattered the stones on his body with all his strength, and rushed out of the cave.

Just now, his mind moved, and he thought about whether Yan Zhen was really in some kind of danger.

Why didn't anyone else ask him for help, but Yan Zhen asked him for help!!

It was precisely because of this thought that Gu Yaowang, who had been suppressed to the extreme, suddenly erupted and instantly devoured his spiritual intelligence.

As if he was controlled, he frantically rushed out of the cave to find Yan Zhen......
