That's his system, what is the basis for the demon beast corpses consumed?

Li Fenghua's guess should be to judge how much conversion time will be increased based on the cultivation of this demon beast's corpse.

After all, the system doesn't know which materials on the corpses of these demon beasts are scarce and rich in the immortal cultivation world.

However, all this was Li Fenghua's temporary conjecture, in order to verify it, he felt that it was still necessary to buy some different demon beast corpses separately, and then verify it.

In this way, after Li Fenghua turned around, he bought the corpses of demon beasts at three different prices.

A cheap demon beast corpse only costs six spirit stones, an ordinary demon beast corpse costs ten spirit stones, and a more expensive demon beast corpse costs fifteen spirit stones.

Buying the corpses of these three demon beasts cost Li Fenghua thirty-one spirit stones.

Putting them in a storage bag, Li Fenghua returned from the black market to the Hidden Sun Villa.

Back in the sect, Li Fenghua couldn't wait to verify it.

After all, if his conjecture was true, he would have to save a lot of spirit stones later.

He first moved the corpse of the demon beast that he had purchased for only six spirit stones into the system space.

After the corpse of this demon beast was completely decomposed by the system space, a number [23:59:59] was displayed on the system interface.

When Li Fenghua saw this string of data appear, he breathed a sigh of relief in his heart.

He didn't expect that it was really as he had guessed, that the system space was not judged by the value of the demon beast's corpse, but by the demon beast's cultivation.

In order to verify his conjecture and whether this was really the case, Li Fenghua hurriedly put the demon beast corpse purchased by ten spirit stones and the demon beast corpse purchased by fifteen spirit stones into the system space respectively.

When the system space completely decomposed the corpse of the demon beast purchased by the ten spirit stones, that string of data became [47:58:29].

After the corpse of the demon beast purchased by the fifteen spirit stones was also completely decomposed by the system space, that string of data became [71:56:59] again.

At this time, Li Fenghua dared to be 100% sure that the system space was not given time according to the value of the demon beast corpse, but according to the cultivation of the demon beast corpse.

The cultivation of these three demon beast corpses was all at the first level of qi refining, so they could only add twenty-four hours of transformation time.

Not according to their value, when Li Fenghua confirmed this matter, he was going to go to the black market after two days.

When the time comes, take all the remaining spirit stones on your body to buy the demon beast corpse with six spirit stones.

Not only that, but he also made plans for the next time he went out to kill the demon beast.

That is, try to kill those high-value demon beasts, and then take these high-value demon beasts to the black market to sell, and then use the spirit stones sold to buy the corpses of the demon beasts with six spirit stones.

In this way, he achieves the best value for money.

Judging from his half-year experience, every time the sect stipulates that within a few days of going out, he can kill four demon beasts with a layer of qi refining, and when he goes out twice a month, he can kill eight demon beasts.

Each time he handed over two demon beasts to the sect, he had two left.

That is to say, after two times, there can be four left, if these four demon beasts are all the kind of demon beasts worth fifteen spirit stones, you can exchange these four demon beasts for eight demon beasts worth six spirit stones.

The reason why a demon beast with fifteen spirit stones can only be exchanged for two demon beast corpses with six spirit stones is because when it is exchanged for it on the black market, the difference in price must be charged.

Even so, Li Fenghua can earn eight more heads per month, which means that his system space can run for eight more days.

Coupled with the resources issued by the sect every month, because he only plans to hand over four demon beasts in the future, then he can also get seventy spirit stones a month.

If all these seventy spirit stones are purchased from the kind of Qi refining first-layer demon beast with six spirit stones, they can be exchanged for eleven heads.

In this way, he can continuously transform the system space for nineteen days a month, which means that his cultivation speed in nineteen days in a month is three times that of a normal person.

Thinking of this, Li Fenghua's whole person became excited, after all, this is the cultivation speed when the system has just been opened, and it will be even faster in the future.

And so it went by for another two days.

As soon as Li Fenghua arrived in two days, he was modified, and rushed to the black market on a dark and windy day for a month.

This time, after Li Fenghua walked around, he stopped next to the corpse of the demon beast with a price of six spirit stones.

Finding the clerk, under his soft grinding and hard soaking, the clerk finally agreed to buy ten of these demon beast corpses with fifty-nine spirit stones for one layer of Qi refining.

The reason why the clerk agreed was because it was rare for him to buy such a low-priced demon beast corpse at one time.

In addition, it is difficult to sell this kind of low-priced demon beast corpse, so when he saw that someone bought so much at once, he agreed to Li Fenghua's request.

After putting the corpses of ten demon beasts on the first level of qi refining into the storage bag, Li Fenghua did not stop.

After returning to the sect, he moved the corpses of these ten demon beasts into the system space.

At this time, the data of the system interface also changes again [264:31:54].

After confirming that it was correct, it was indeed an additional ten days before Li Fenghua retreated from the system space.

Thinking about another question, because a few days ago, the system sent him an unlock quest again, and this unlock quest was about the upgrade of the anchovy grass he planted.

He needs to kill a hundred heads and refine a layer of demon beasts to upgrade the phoenix tail grass planted in his spirit field.

After upgrading, the power of cultivation generated every 24 hours is increased by one day.

That is to say, the current anchovy grass, if upgraded, will be upgraded from the power of cultivation that transforms for two days every day to the power of cultivation that transforms for three days every day.

Don't underestimate the increase in the power of cultivation on this day, over the years, the accumulation is very considerable.

Increasing one's cultivation by one day can increase by one year by one year, which is a direct increase in cultivation speed compared to those ordinary immortal cultivators.

Coupled with his own daily meditation and cultivation, then his speed is equivalent to improving his cultivation power for four days a day.

After understanding this, Li Fenghua couldn't wait to go out and kill the demon.

In this way, after a few days, it was finally time to go out to kill demons and demons.

After obtaining the specific location of the first-level demon beast of Qi refining from the sect, Li Fenghua went down the mountain alone.

This time, Li Fenghua did not choose a remote place alone like last time.

The reason why he had to go to a remote mountain village to kill the demon beast last time was because he had no requirements for the quality of the demon beast at that time, as long as it was a demon beast.

But now he found that monsters with high material value can go to the black market to exchange for many monsters with low value.

This allowed him to triple the time it took to convert his system.

So he decided to try his luck in the area where the high-value monsters were.

In the previous six months, because it didn't have much to do with his own interests.

So he hasn't been to this kind of area, but now that he has found that he can increase the time for his system to change, he can only compete with his peers for this kind of demon beast.
