Myth analysis, I know the plot and I am invincible

Chapter 1346: Inferior Transformation

After retching for a long time, nothing came out.

No way, the strength of his gastric juice is estimated to be stronger than aqua regia, which is a combination of nitric acid, sulfuric acid, and strong acid.

Metals like silver melted, let alone the flesh and blood of monsters.

It took a long time for Li Su to calm down and accept what happened just now.

After all, it's all digested. What else can I do if I don't accept it?

Damn, I have to be careful when eating in the future. At least when eating, I must concentrate and not be too distracted.

Touched my belly.

You know what, although this monster is only two hundred pounds, the nutrition is really good.

It's more than a thousand pounds, it should belong to the two to three thousand pounds level, that is, the monster of the true essence period.

As it digested, the feeling of fullness brought by the previous 1,500 taels of silver weakened a lot, and it felt like I could eat a lot of stones again.

Facing his own conclusion, Li Su shuddered inexplicably.

Damn, what's up with this talent?

It feels like it's not just expanding his diet? It feels like it's even changing the range of things he wants to eat.

Under normal circumstances, as a human being, and Li Su is still the kind of person who has maintained human habits for thousands of years, even if he can eat stones, it stands to reason that for a while, he won't really treat that thing as an object to eat.

What's the result? He just had this idea naturally.

Thinking back, when he ate the lizard-like thing just now, he almost stuffed it into his mouth subconsciously without any thought at all.

You know, lizards, especially wild ones, usually carry a lot of bacteria.

For example, in the previous life, the giant lizard called Ke? It contained more than 60 kinds of bacteria in its body, and the bison couldn't stand it when it licked it.

At this point, a demon beast-level lizard obviously can't be weaker than that thing, right?

But for such a thing, he didn't even think about whether it was poisonous or not, and swallowed it in one gulp.

Thinking of this, Li Su's physical discomfort, which he had suppressed with great difficulty, immediately began to stir again.

******

In order to avoid continuing to worry about that problem, Li Su directly trotted deep in the vein.

Originally, this was a very dangerous behavior.

After all, the temperature difference of the vein is not a gradual increase, but once it crosses a certain node, the temperature drops sharply.

That is to say, he eats everything and has a strong body. Otherwise, if he runs so wildly, he will not freeze to death, or at least freeze off an arm and two legs.

All the way, he advanced more than ten miles.

Here, the temperature is close to minus fifty degrees.

Of course, this is just his estimate, and the exact amount is uncertain.

The Yin Qi is very strong.

Outside, there is one layer of Yin Qi, half a layer of spiritual Qi, and the rest is air, which is probably such a division.

Here, the Yin Qi has reached at least three layers, the spiritual Qi is still half a layer, and as for the air, it has dropped directly to five and a half layers.

Well!

It seems that I still underestimated this Yin Stone vein.

Judging from the current situation, let alone minus 100 degrees, minus 80 degrees, he would probably be a little annoyed.

If it is to build the foundation, I am afraid that it will not move forward at around minus 50 or 60 degrees.

It is not that the temperature cannot be tolerated, but that the instinct as a living being is ignored.

That is breathing air!

Whether it is practicing Qi or building the foundation, breathing is required, and this will undoubtedly greatly reduce the resistance to Yin Qi.

After all, in one breath, the Yin Qi inside alone is enough to offset most of the heat energy in the body.

Obviously, even if the acquired turns to the innate and the method of fetal breathing is mastered, it will not work.

After all, fetal breathing is not not breathing, but not through the mouth and nose, which Li Su can also do.

For a while, Li Su, who was originally planning to go deeper, chose to stop and planned to look around first.

At such a concentration, the formation of Yin Stone will be much simpler.

At least, the conditions for the birth of low-grade Yin Stone are already there.

At this depth, the environment of the Yinshi ore vein is undoubtedly quite complex, with many caves.

Some are naturally formed, and some are opened later.

The ones opened later are basically divided into two types, one is relatively large, a typical work of cultivators, and the other is short and round, which should be left by monsters.

Fortunately, although his body was restricted, his soul was not.

Li Su directly released the induction and began to feel the distribution and changes of the surrounding Yin Qi through his own soul.

This is almost his trump card.

It can be said that the reason why he chose to go down to the mine to make money instead of other things has a lot to do with his soul not being afraid of Yin Qi.

After all, ordinary cultivators dare not release their spiritual sense in such places to sense the flow of Yin Qi. After all, this thing can directly affect the soul like pure Yang Qi.

Although it is different from pure Yang Qi in that it can directly kill the soul, it can reduce the activity of the soul and eventually freeze the spiritual sense.

Therefore, he only needs to go deep enough and then release the spiritual sense to sense. Even if the vicinity has been explored, there will always be some fish that slip through the net, right?

Not to mention!

Not long after sensing it, Li Su opened his eyes and turned his gaze directly to a cave as tall as a person.

It was a cave made by a cultivator, and there were different fluctuations in the depths.

It must be Yin Stone!

Without hesitation, Li Su ran in directly, and stopped after walking for nearly a mile. Then he stretched out his hand and dug a wall on one side.

The geology is really hard.

Perhaps because of the cold, it is almost equivalent to frozen soil, and it feels stronger than steel.

Li Su stopped after digging almost one meter deep. His eyes lit up slightly, and he took out a stone as big as the knuckle of his little finger.

The color is quite pure, especially the Yin Qi inside, which is very rich.

It is almost equivalent to the low-grade Yin Stone. The only bad thing is that it is too small and can't reach the amount of one.

A normal low-grade Yin Stone should be about five taels, and the size should be just over a thumb.

This is at most one-third.

Although it is not much, it is undoubtedly a good start, and it also means that his plan is indeed feasible.

After all, this location has obviously been visited by many people before, and most places have been visited back and forth countless times. This small piece in front of him is undoubtedly a fish that has slipped through the net.

He took out his Qiankun bag and the jade box specially used by Baimo Palace to store Yin stones.

This was the only thing Li Su rented when he came down.

It was not expensive, but it was limited. After all, it was specially used to store wild Yin stones, and it could only be rented by those who were at the foundation building level or above.

??????55.??????

However, fortunately, as the successor of Moyuan Peak, he really couldn't afford to rent this thing.

It was not a problem of rent, but a problem of deposit.

After all, there were precedents of people who died in the depths of the mines after the foundation building, or the jade box was destroyed.

Putting the Yin stone in, Li Su continued to move.

It must be said that he was very efficient through his spiritual sense.

After a while, he found seven or eight pieces one after another. Although they were not complete low-grade spirit stones, they were almost equivalent to two pieces in total.

This efficiency is really good!

Two low-grade Yin stones can be exchanged for about twenty low-grade spirit stones.

Although twenty low-grade spirit stones are not many, they can't even buy a Guiyuan Pill. Well, at this price, the demon cultivators really can't buy it. Only ten of them are available in the righteous sect. The demon cultivators buy them on the black market, and the price is generally around thirty. At the most expensive time, it can even reach sixty.

It must be said that the demons may be cruel and brutal, but when it comes to making money, they are really unworthy of carrying shoes.

Back to the topic.

It took him only ten minutes to collect two low-grade Yin stones.

This undoubtedly shows the feasibility of his plan!

After all, he will continue to go down, and there will be more and more fish that slip through the net. Needless to say, the quality of the shipment will naturally get better and better.

Li Su will definitely not ship in large quantities, which will make people suspicious.

After all, this is the Demon Sect. If he has any special means of collecting Yin stones, not to mention the foundation building will be tempted, even the old demon of the Golden Core will probably be restless.

What he needs to do is to find large-sized low-grade Yin stones.

That grade, if you take one out, it will still not be enough, but at least it can offset some of the consumption.

And that's enough!

Although he decided to support himself, it doesn't mean that Li Su really intends to take full responsibility.

Just kidding, he is not a good 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 the psychological expectation, there is still a possibility of giving up, that is to say, it is unstable.

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

When the other party invests more, it is extremely huge, and pours in hard work, then he can be a parasite at ease and suck the other party's blood crazily.

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

Continue all the way down.

From minus fifty degrees, fifty-five degrees, sixty degrees.

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

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

However, in half a day, the latest piece was taken out, which was almost the size of a fist, close to five catties, equivalent to the weight of ten stones.

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

You know, the larger the volume of the Yin Stone, the higher the price.

To put it simply, the kind of five taels of a complete low-grade Yin Stone is worth ten low-grade spirit stones.

But the incomplete kind below five taels, it takes about six taels to sell ten low-grade spirit stones.

Looking back, what about the six taels of Yin Stone? Thirteen low-grade spirit stones.

Then what about the ten taels? Almost thirty low-grade spirit stones can be sold.

Now, how much is this five-jin low-grade Yin Stone that Li Su recently discovered? At least it can be sold for about two medium-grade spirit stones.

Here, we need to understand that although one medium-grade spirit stone is equal to one hundred low-grade spirit stones.

But that is a medium-grade exchange for a low-grade one. Conversely, a low-grade exchange for a medium-grade one cannot be exchanged. At least a 20% premium is required.

In other words, the five-jin stone in front of him is basically equivalent to two hundred and forty low-grade spirit stones.

Hmm?

Just when Li Su was full of joy, his expression suddenly paused, his pupils couldn't help shrinking slightly, and he looked up directly into the depths of the Yinshi mine.

Yin Qi, a lot of Yin Qi.

It was rolling in a certain direction.

This movement was not small.

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

Faced with this scene, even with Li Su's mentality, he still couldn't help being shocked.

You know, the range he sensed was not the center of the vibration, but the edge. The edge was more than a mile, so how big would it be to spread from the center to all directions.

Not only that, this kind of fluctuation is not the fluctuation of low-grade Yin stones.

Of course, he didn't want it to be the fluctuation of middle-grade spirit stones. After all, at his current location, he was still dozens of miles away from the appearance of middle-grade spirit stones.

I'm afraid that at least in the area after minus 100 degrees, it is possible for middle-grade spirit stones to appear, and they are the kind with extremely low integrity.

This is probably an advancement!!!

The volume of the low-grade spirit stone is large enough, and it has not been discovered. During this period, it has been constantly nurtured and accumulated, and finally broke its own upper limit and advanced to the middle grade!

Immediately, Li Su's eyes lit up.

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

The value of medium-grade Yin Stone is not small.

It only needs to be the size of a finger joint, and it can be sold at least thirty or more medium-grade spirit stones.

You know, to be able to become a medium-grade Yin Stone, its size is at least the size of a finger joint.

And obviously, like low-grade Yin Stone, the higher it is, the more expensive it will be. If it is a complete piece, it can be sold for about 100 medium-grade spirit stones.

What is the concept of 100 medium-grade spirit stones?

It is almost equivalent to one-third of the property of the Jindan old demon.

I am really sleepy, and a pillow is sent to me!

Take a breath, there are obviously other low-grade Yin Stones next to him, but at this moment Li Su doesn't care, and runs directly to the center of the Yin Qi fluctuation.

This thing must be obtained, and I can't wait for a moment. If I wait, there may be accidents.

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

Deeper in the vein, a huge figure was also running wildly. It dug all the way up. The direction it was heading to was undoubtedly the center of the Yin Qi fluctuations that Li Su was heading to.

Obviously, it was not just Li Su.

This huge figure also discovered that the low-grade Yin Stone had advanced to the middle-grade Yin Stone!
