Myth analysis, I know the plot, I am invincible

Chapter 1346: Lower Grade Transformation

He retched for a long time, but naturally nothing came out.

There's no way. The strength of his gastric juice is probably even stronger than aqua regia. It's a combination of nitric acid, sulfuric acid, and strong acid.

Even metal like silver would melt into it, let alone the flesh and blood of monsters.

It took Li Su a long time to calm himself down and he reluctantly accepted what had just happened.

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

Damn, I have to be careful when eating next time. At least when eating, I have to concentrate and not let my mind wander too much.

Touched the belly.

You know what, even though this monster weighs only 200 kilograms, it’s really nutritious.

It's over a thousand jin, so it should be between two and three thousand jin, which is a monster in the True Essence Stage.

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

Faced with his own conclusion, Li Su shuddered inexplicably.

Damn, what’s up with this talent?

It seems that he has not only expanded his diet, but also changed the range of food he wants to eat.

Under normal circumstances, as a human being, Li Su is one of those people who have maintained human habits for thousands of years. Even if stones can be eaten, it stands to reason that he would not really regard that thing as something to be eaten for a while.

What was the result? He just came up with this idea naturally.

Thinking back, when I ate that lizard-like thing just now, I almost put it in my mouth subconsciously without any thought at all.

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

For example, in the previous life, the monitor lizard was called something or other. It contained more than 60 kinds of pathogens in its body, and even a buffalo couldn't stand being licked by it.

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

But he swallowed it in one gulp without even thinking about whether it was poisonous or not.

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 started jogging deep into the mine.

In fact, this is a very dangerous behavior.

After all, the temperature difference in the mineral vein does not increase gradually, but once it crosses a certain node, the temperature drops sharply.

It was because he enjoyed everything he ate and was in good health, otherwise, if he ran so wildly, he would have frozen to death, or at least lost an arm and both legs.

Along the way, we advanced more than ten miles.

Here, the temperature is approaching minus fifty degrees Celsius.

Of course, this is just his estimate, and the exact amount is not certain.

The yin energy is very strong.

Outside, there is a layer of yin energy, half a layer of spiritual energy, and the rest is air. This is roughly the division.

Here, the Yin energy has reached at least the third level, the spiritual energy is still half a level, and as for the air, it has directly dropped to the fifth and a half level.

Um.!

It seems that I have underestimated this Yinshi mine.

Judging from the current situation, let alone minus 100 degrees, even minus 80 degrees would probably make him a little annoyed.

If you want to build a foundation, I'm afraid you won't be able to move forward if the temperature is around minus fifty or sixty degrees Celsius.

It’s not that we can’t bear the temperature, but that we ignore our biological instincts.

  That's the breath of 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, with one breath, the Yin energy inside is enough to offset most of the heat energy in the body.

Obviously, even if one transforms acquired into innate, and masters the method of fetal breathing, it won't work.

After all, fetal breathing does not mean not breathing, it just means not breathing through the mouth and nose, which Li Su can also do.

For a moment, Li Su, who had originally planned to go deeper, chose to stop and 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 have been met.

At this depth, the environment of the Yinshi mine is undoubtedly quite complex, with numerous caves.

Some are naturally formed, while others are artificially created.

These acquired openings are basically divided into two types. One is relatively large, a typical work of cultivators, and the other is short and round, probably left by monsters.

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

Li Su immediately released the sensation and began to feel the distribution and changes of the surrounding Yin energy through his own soul.

This is almost his trump card.

It can be said that the reason why he chose to go mining to make money instead of doing other things has a lot to do with the fact that his soul is not afraid of negative energy.

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

Although it is different from pure yang energy that can directly kill the soul, it can reduce the activity of the soul and eventually freeze the consciousness.

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

  Don’t say it yet!

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

It is a cave dug by monks, and there are different fluctuations in the depths.

It must be Yin Stone!

Without hesitation, Li Su ran straight in and stopped after walking about a mile. Then he reached out and started to dig at one side of the wall.

The geology is really tough.

Maybe it's because of the cold, it's almost like permafrost, and it feels stronger than steel.

Li Su stopped after digging nearly 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 energy inside, which is very rich.

It is almost equivalent to a low-grade Yin stone. The only bad thing about it is that it is too small and cannot be counted as one.

Normally, a low-grade Yin Stone should weigh about five taels and be just the size of a thumb.

This is at most one third.

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

After all, it is obvious that many people have come to this location before, and most places have been visited back and forth countless times. The small area in front of us is undoubtedly a fish that has slipped through the net.

He took out his Qiankun bag and took out the special jade box from Baimo Palace which was used to store Yin stones.

This was the only thing that Li Su rented when he came down. It wasn't expensive, but it had restrictions. After all, it was specially used to store wild Yin stones, and it could only be rented if one was at the foundation-building level or above.

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

It’s not a question of rent, but a question of deposit.

After all, there are precedents of people dying deep in the mines while trying to build their foundation, or having their jade boxes destroyed.

After putting the Yin Stone in, Li Su continued to act.

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

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

This efficiency is really good!

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

Even though twenty low-grade spirit stones are not a lot and cannot even buy a Guiyuan Pill, at this price, the demon cultivators really cannot buy it. Only the righteous ones can get ten of them. If the demon cultivators buy them on the black market, the price is generally around thirty. At the most expensive time, it can even reach sixty.

It has to be said that the demons may be brutal and cruel, but when it comes to making money, they are not even worthy of carrying shoes.

Back to the topic.

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

  This undoubtedly proves the feasibility of his plan!

After all, he will continue to move forward, and more and more fish will slip through the net, so the quality of the shipment will naturally get better and better, needless to say.

Li Su would definitely not ship large quantities of goods as it would arouse suspicion.

After all, this is a demon sect. If he has some special means of collecting Yin stones, not to mention that the foundation-building cultivator would be tempted, even the Jindan demon would probably not be able to sit still.

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

Of that quality, if one was taken out, although it would still not be enough, it could at least offset some of the consumption.

  And that is enough!

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

Just kidding, he is not a pushover.

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 expectations, there is still a possibility of giving up, which means it is unstable.

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

When the other party has invested more and it becomes huge, and has poured in a lot of effort, then he can be a parasite and suck the other party's blood madly.

After all, at that time, the person who couldn't stop would not be Li Su, but the withered old man himself.

Continue all the way down.

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

Li Su's gains were undoubtedly growing bigger and bigger.

It upgraded gradually from one third of a low-grade Yin Stone to two thirds, and then to a complete one.

However, in less than half a day, the latest piece taken out was almost the size of a fist and weighed nearly five pounds, equivalent to the weight of ten pills.

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

You know, the larger the Yin Stone is, the higher the price will be.

To put it simply, a complete low-grade Yin stone weighing five taels is worth ten low-grade spirit stones.

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

Looking back, where are the Yin stones that weigh six taels each? Thirteen low-grade spirit stones.

What about ten taels? It can be sold for about thirty low-grade spirit stones.

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

Here, one thing needs to be understood, although one medium-grade spirit stone is equal to one hundred low-grade spirit stones.

But that is exchanging medium-quality goods for low-quality goods. Conversely, it is impossible to exchange low-quality goods for medium-quality goods. It must be at least at a premium of 20%.

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

  Ok?

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

Yin energy, lots of yin energy.

Rolling towards a certain direction.

This is quite a big commotion.

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

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

You know, the range he senses is not the center of the vibration, but the edge. The edge is more than one mile away, so how big will it be when it spreads from the center to all directions?

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

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

I'm afraid that only in areas at least below minus 100 degrees can medium-grade spirit stones appear, and they are of extremely low integrity.

This is probably advanced!!!

The inferior spirit stone was large enough and had not been discovered, so it continued to grow and accumulate, eventually breaking its own upper limit and advancing to the mid-grade!

Immediately, Li Su's eyes lit up.

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

The value of a medium-quality Yin stone is undoubtedly enormous.

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

You know, to be a mid-grade Yin Stone, its size must be at least as big as a finger joint.

And obviously, just like the lower-grade Yin Stone, the higher the quality, the more expensive it will be. If it is a complete piece, it can be sold for about one hundred middle-grade spirit stones.

  One hundred medium-grade spirit stones, what does that mean?

It is almost equivalent to one third of the wealth of the Jindan demon.

I'm really sleepy, please send me a pillow!

He took a deep breath. There were obviously other low-grade Yin stones nearby, but at this moment Li Su didn't care about them and ran directly towards the center of the Yin energy fluctuations.

This thing must be obtained, and we cannot wait even a moment. If we wait, something unexpected might happen.

  *******

Of course, just as Li Su was rushing towards the center of the Yin energy fluctuations.

Deeper in the vein, a huge figure was also running wildly. It dug all the way up. There was no doubt that the direction it was heading was exactly where Li Su was heading, the center of the yin energy fluctuations.

Obviously, it's not just Li Su.

This huge figure also discovered that the low-grade Yin Stone was advancing to the medium-grade Yin Stone!
