No wonder those disciples in the True Qi stage looked so ugly and were very resistant to mining in the lower mine veins.

Even in the outermost layer, the yin energy is not too rich.

The chill is very serious, and the temperature drops sharply, which is almost equivalent to directly running from more than 20 degrees to zero degrees.

Once a monk succeeds in practicing Qi, his tolerance to the ambient temperature will indeed increase.

But that's just a change within a dozen degrees.

For example, between several degrees, and the further down, the less uncomfortable it is.

In terms of the True Qi period, you can basically achieve a fearless level of about five degrees, but once you reach about two degrees, you need to use your skills to resist the invasion of coldness.

As for the zero degree, even if it is in the true qi period, it may be frozen to death after a certain period of time.

After all, as a normal situation, the zero-degree environment is no longer suitable for most life survival and is a very harsh environment.

Even Li Su, in his current situation, once the temperature is below the negative 80 degrees, it will almost begin to feel the impact.

After that, basically every five degrees drops, this impact will intensify exponentially.

If you exceed zero Baidu, you have to use the tactics to increase blood flow through the heart and maintain body temperature.

In the foundation-building stage, it is almost the same as it is.

Of course, they are better than Li Su. They are basically not affected by the range that Zhengang can withstand, and the cold will be completely isolated.

However, their corresponding burst abilities will be very poor.

Although Li Su will be greatly affected by Baidu at zero, even if he suddenly encounters a sudden drop in temperature, he can still withstand the negative ten degrees or twenty degrees.

The foundation-building stage will not work. Once you exceed the scope of the true gang, you will be frozen to death directly.

Yinshi ore is still good.

It can be regarded as the few specialty products that can be produced by the Hundred Demon Palace. In Qianzhou, it is also quite good supplies and sold very well.

Mainly, there are many places to use.

You can use it in practice, alchemy, weapon refining, etc.

By the way, by the way, Yin Qi does not equal the Demonic Way. There are many martial arts that mainly focus on Yin in the righteous sect.

Although the value is not low, it is also related to the quality of the obtained Yin stone, which is similar to the spirit stone.

The purer the yin energy inside, the higher the concentration, the more expensive it is.

For example, the best-quality yin stone is almost pure black and without any impurities. It is the price of a thousand top-quality spirit stones that only require a slap of the size of a palm. It can definitely be said to be a sky-high price.

Of course, that level can only be thought about.

Not to mention Li Su, even if he discovers it, he can't get it.

After all, the cold air released by the top-level Yin stone is the height that even the soul can freeze you.

Although Li Su's soul is not afraid, if he really encounters it, his body will be frozen in an instant.

But, then again.

There may be the best Yin stones in the Netherworld Mountains, but obviously there is no such thing as the Hundred Demon Palace.

The yin energy here is not enough.

Only when the deepest terrain of the Netherworld Mountains is the center where the yin energy finally gathers can it be produced.

Judging from Li Su's existing information, it is probably possible that there is a Yinhe group gathering point at the foot of the Buzhou Mountains on the north side of the Netherworld Mountains, near the Xuanzhou Continent, which is known as the Yellow Springs and Styx Rivers.

Anyway, in a word, it is basically not what he can imagine now.

In that place, even the immortals had to hesitate on the spot, and the old demon of Jindan entered and died.

It's so scary there.

*******

Following the mine veins, walking downward for about a kilometer, Li Su suddenly sighed and was full of sympathy for the true qi disciples of the Hundred Demon Palace.

Suddenly, I understood what the pile of waste sharks placed at the entrance, and what the big one with the words "rental" on the side meant.

As I went down, the mine was so clean that it seemed like I was licked by a dog.

Not to mention the Yin stones, he hadn't even seen Yin scum.

Therefore, it is basically impossible to collect directly unless your luck is against the will of heaven.

In other words, if the disciples who came down to obtain the Yin stones, they could only use one way, which was to rent the stones whose Yin energy was consumed, go down into the ore vein, find one, or dig a hole, and move in.

Using your own true qi as a guide, pour the yin energy into the dried yin stone.

In terms of the True Qi period, even if the little finger is as big as the knuckle, it will take at least one week to fill it.

After all, at most one or two hours, people will not be able to withstand and have to go out.

The most terrifying thing is that if you complete this kind of work, you will only get ten taels of silver if you want to complete it once.

To be honest, the purchasing power is not low. There is monster meat every time you spend, although it is not much, it can be enough for a month.

I struggled for seven days and had a rest for the remaining twenty-three days, and I had meat to eat. Isn’t it a good feeling?

So, do you know why the Hundred Demon Palace gave such conditions?

Because, if this is not the case, the disciples of the true qi cannot withstand it. By relying on food alone, they cannot eliminate the hidden dangers caused by the yin energy to the body. That is to say, if you do not eat meat, as long as you continue to go to the mine more than twice, the disciples of the true qi stage will basically be abandoned.

Don’t look at Li Su’s quick practice of Qi. Under normal circumstances, it takes at least one month for ordinary people to practice Qi. However, it can start at least half a year after they can go to Yinshi Mine.

In half a year, what he eats and drinks can only be provided for free on Hundred Demon Palace.

Therefore, ten taels of silver are not the generousness of the Hundred Demon Palace, but to ensure that there are endless disciples of the True Qi stage to come to mining.

There is no way, just by drawing air into the stone, it eliminates the possibility that mortals can participate.

In addition, although Yin Qi is fatal to the living, it is another matter to the dead, especially the kind of dead who dies with resentment.

Otherwise, the scene of the mineral vein of the Hundred Demon Palace is probably not as harmonious as it is now.

Li Su didn't stop and walked in deeper.

This chapter is not finished yet, please click on the next page to continue reading the exciting content below! Twenty degrees below zero are almost within the scope of the True Yuan period. There is no doubt that the yin energy here is much richer than the True Qi period.

If it is to draw qi into the stone, it will take a week to complete it outside, and it can be done here for at most half a day.

It can be said that if you can collect it here, you can not only easily earn food expenses, but also quickly accumulate money.

I guess it takes three to five years to buy not only a large number of elixirs for practice, but also one or two magic tools.

It sounds like, does it feel that the situation of disciples in the True Yuan stage is much better than that in the True Qi stage?

Haha, I can only say that I am thinking too much.

From Li Su walking into this place, he felt his sight, something was looking at him silently.

The environment of Yinshi Mine is indeed harsh and is a forbidden area for ordinary creatures.

But obviously, it cannot help the monster.

They are naturally strong in nature, and it is undoubtedly much less difficult to enter and exit here than others.

Moreover, for humans, the meat of monsters is extremely nutritious, and the same is true, especially after being trained. For monsters, it is almost the same as steak with salt and black pepper, which is so irresistible.

Therefore, although the income of disciples in the True Yuan period has increased significantly, in fact, the probability of them being attacked by monsters is also very high.

After all, disciples in the True Qi stage basically do not go too deep into the mine cave, and are directly at the door. Once they hear the movement, they will run away immediately. Therefore, although they are not strong, the number of people killed by monsters is not large.

On the contrary, the True Yuan period is different. If you want to make money quickly, you must go deeper.

However, the magic power of the True Yuan stage cannot achieve the defense like steel in the Foundation Establishment stage, and the physical body is not strong.

Once approached by a monster, the probability of death in the True Yuan period is very high.

Therefore, when the True Yuan period comes, you often find the hill where you are and "rental" some defensive magic weapons.

Otherwise, how could there be such a situation where there are thousands of disciples in the Hundred Demon Palace, but they only build a foundation but only have just one hundred?

Without caring about staring at his own eyes, Li Su continued to go deeper.

His goal is on the foundation building area.

After all, only when you get there can you have the chance to encounter wild Yinshi.

Although drawing qi into stone is also a way to collect yin energy, that kind of yin stone is of very low value. After all, the qi of a monk is itself an impurity for pure yin energy.

Those who can really sell at a price, not silver, must be pure natural wild yin stones.

Even if your thumb is as big as a piece, you can almost sell the lowest-grade spirit stones.

Li Su is not just talking about making money by herself.

As Li Su continued to deepen, gradually, his eyes began to change when he stared at him, and the murderous intent gradually became stronger.

Although monsters have greater resistance to yin energy than monks, they have their limits.

So, keep going, it can't follow.

Under normal circumstances, when facing a monk like Li Su who can continue to go deeper, the monster should give up.
To be continued...
