This undoubtedly shows the feasibility of his plan!

After all, he will continue to move downwards, and more and more fish will slip through the net. Needless to say, the quality of shipments will naturally get better and better.

Li Su will definitely not do mass shipments, which will make people suspicious.

After all, this is a demon sect. If he has any special means of collecting Yin Stone, not to mention the Foundation Establishment Association, even the Golden Pill Old Demon may not be able to sit still.

What he wants to do is to find a large, low-grade Yin Stone.

If you take out one of that grade, although it is still not enough, it can at least offset part of the consumption.

And this is enough!

Although she decided to support herself, it does not mean that Li Su really planned to take full responsibility for herself.

Just kidding, he's not a bad guy.

The reason for changing the plan is mainly because the other party has not invested enough. Although it is an opportunity, once the investment exceeds psychological expectations, there is still the possibility of giving up, which means it is unstable.

Therefore, he took the initiative to appease the other party.

Later, when the opponent invests more, becomes extremely large, and pours in hard work, then he can peacefully be a parasite and suck the opponent's blood like crazy.

After all, when that time comes, the person who can't stop is not Li Su, but the dry old man himself.

Continue all the way down.

From fifty degrees below zero, fifty-five degrees, sixty degrees.

Li Su's harvest is undoubtedly getting bigger and bigger, more and more.

From one-third of a low-grade Yin stone, it gradually became two-thirds, then to a complete one, and gradually upgraded.

However, within half a day, the latest piece was taken out and it was almost the size of a fist, weighing nearly five kilograms, equivalent to the weight of ten pills.

Facing this scene, Li Su couldn't help but smile.

You know, the larger the volume of Yinshi, the higher the price.

To put it simply, five taels per piece, a complete low-grade Yin Stone, is worth ten low-grade spiritual stones.

But if it is less than five taels and is incomplete, it will take almost six taels to sell ten low-grade spiritual stones.

Looking back, where are the six taels of Yin Stones? Thirteen low-grade spiritual stones.

What about the twelve taels? It can sell almost thirty low-grade spiritual stones.

Now, Li Su has recently discovered this low-grade Yin Stone weighing five kilograms. How much does it cost? At least he can sell about two mid-grade spiritual stones.

Here, we need to understand one thing, although one middle-grade spiritual stone is equal to one hundred low-grade spiritual stones.

But that would be to exchange a middle-grade product for a lower-grade one. On the other hand, it would be impossible to exchange a lower-grade product for a middle-grade one. It would require at least a 20% premium.

In other words, the five kilograms of stone in front of you is basically equivalent to two hundred and forty low-grade spiritual stones.

Um?

Just when Li Su looked happy, his expression suddenly paused, his pupils couldn't help but shrink slightly, and he looked up directly into the depths of the Yin Stone vein.

Yin Qi, a lot of Yin Qi.

It is rolling away in a certain direction.

This movement is not small.

Even though he was far away, he could still feel that the Yin Qi that was at least more than a mile wide within the range of his spiritual consciousness was being moved.

Facing this scene, despite Li Su's mentality, he couldn't help but be shocked.

You must know that the range he senses is not the center of the vibration, but the edge position. The edge position is more than one mile, so how big will it spread from the center position to all directions.

Not only that, this kind of fluctuation is not something that low-grade Yin Stone can have.

Of course, he didn't want it to be the fluctuation of the middle-grade spiritual stone. After all, where he was currently, he was still dozens of miles away from the appearance of the middle-grade spiritual stone.

I'm afraid that it would take at least an area after Subzero Baidu to find a mid-grade spiritual stone, and it would still be the kind with extremely low integrity.

This is probably an advanced step!!!

The size of the low-grade spiritual stone is huge enough, and it has not been discovered. During this period, it continues to breed and accumulate, and finally breaks its upper limit and advances to the middle-grade!

Immediately, Li Su's eyes lit up.

I originally just wanted to get a larger lower-grade Yin Stone back, but I didn't expect that the first time I went into the mine, I encountered a situation where the low-grade Yin Stone was upgraded to a medium-grade one.

A medium-grade Yin stone is of great value.

It only needs to be about the size of a knuckle, and it can be sold for at least thirty yuan for a medium-grade spiritual stone.

You must know that to be able to become a middle-grade Yin Stone, its size must be at least as big as a knuckle.

And obviously, just like the low-grade Yin Stone, the higher it goes, the more expensive it will be. If it is a complete piece, it can sell for almost one hundred middle-grade spiritual stones.

One hundred middle-grade spiritual stones, what is the concept?

It is almost equivalent to one-third of the property of the Golden Elixir Old Demon.

I'm really sleepy, give me a pillow!

Taking a breath, there were clearly other low-grade Yin stones nearby, but at this moment Li Su ignored them and ran towards the center of the Yin Qi fluctuations.

You must get this thing. You can't wait for a moment. If you wait, something might happen.

*******

Of course, just when Li Su was flying towards the center of the Yin Qi fluctuation.

Deeper in the veins, a huge figure was also running wildly. It was digging all the way up, and the direction it was heading to was undoubtedly the center of the Yin Qi fluctuations that Li Suta was going to.

Obviously, it's not just Li Su.
Chapter completed!
