And the reason why the top-grade spirit stones are so precious is because whether it is a low-grade spirit stone, a medium-grade spirit stone, or an up-grade spirit stone, they are all consumed when they are used up.

Only the best spirit stone can be reused, after the spiritual energy in the best spirit stone is used up, it will become a transparent stone, put this stone in a place with strong spiritual energy, this stone will automatically absorb the spiritual energy, and when the spiritual energy is full, it will be another superb spiritual stone.

It is because of this reusable characteristic that the best spirit stone will be so precious, and the preciousness of the blood sand stone is not inferior to the best spirit stone, every auction, it is basically the best spirit stone to buy, if it is not the best spirit stone, the price is even more expensive.

It is precisely because the blood sand and stone are so precious, even if the blood mist and sand sea are extremely dangerous, there are still countless people who flock to the blood sand and stone, even if they face the danger of life and death.

Since they were passing by the sea of blood mist and sand, Tan Shuangshuang and the others didn't want to go back empty-handed, so they all planned to go in and try their luck to see if they could get some blood sand and stones.

Tan Shuangshuang didn't care if she could get the blood sand stone, she came out to play mainly and relax, so she didn't plan to work as hard as those people, she just planned to take a turn in the relatively safe area of the blood mist and sand sea, and just look at this strange scenery and leave.

Tan Feiyu, Lu Tianyi and Bai Sheng Feihu are all based on Tan Shuangshuang's ideas, and these four are not short of money, needless to say, Lu Tianyi has a lot of money-making means, and there are countless spirit stones.

Although the spirit stones in Tan Shuangshuang and Tan Feiyu's hands are not as good as Lu Tianyi, they both have a lot of fire spirit essences, and this thing is more valuable than spirit stones, as for Bai Sheng, whether he has money Tan Shuangshuang doesn't know, but Bai Sheng is very generous in his daily life, especially for Feihu, any precious elixir is willing to buy for Feihu to eat, and it is obviously not bad money.

As for the only Flying Tiger who has no money, Tan Shuangshuang, his mother, and Tan Feiyu's uncle, are spoiled, and Bai Sheng is used to it, Lu Tianyi is flattered, but he has no money but is the one who is the most lacking in spirit stones, what do you want.

The sea of blood mist and sand is full of dangers, although there are few demonic beasts inside, their combat power is not small, and they are good at sneak attacks in secret, unknowingly taking people's lives, I don't know how many cultivators have fallen under the minions of these demonic beasts.

The location where everyone is is the periphery of the sea of blood mist and sand, there are no powerful magical beasts in this place, only the huge temperature difference between day and night is dangerous, it is hot enough to dry people during the day, and it is cold at night to freeze people into ice lumps in minutes.

This extreme heat and cold is not an ordinary temperature change, but a change caused by a unique spiritual force field, and human beings can only barely resist the damage caused by the temperature change, but they cannot resist the feeling of extreme heat and cold when the temperature changes.

Tan Shuangshuang and Tan Feiyu are both people who cultivate physical cultivation, and they have even experienced the test of extreme cold on the road to heaven, although they are now alternating between cold and hot, but they are running their spiritual power, and they can still stand up to the heat of this sea of blood mist and sand as a kind of cultivation.

The most uncomfortable thing is Lu Tianyi, he can't cultivate, and he is not a physical cultivator, he has been so hot that he has gone crazy after walking in this sea of blood mist and sand for a while, and he can't wait to find a cool place to squat, and never come out again.

Flying Tiger is the same, compared to Lu Tianyi, he is covered in fluff and beautiful on weekdays, but he suffers at this time, he is obviously a big cat, and he is hot all of a sudden, stretching out his pink and tender tongue, and he is left panting.

Bai Sheng is not much better, although he has turned into a human form and has lost his hair, but it may be because he is a big cat, Bai Sheng is particularly intolerant to heat, although he still maintains a cold posture, he didn't stick out his tongue like a flying tiger, but it was also hot.

Tan Shuangshuang looked at the appearance of Lu Tianyi and Bai Sheng Feihu, and felt sorry for Feihu, so he got the Feitian Palace out, and directly opened the protective shield, so that Feihu, Lu Tianyi, and Bai Sheng all entered the Feitian Palace, and then directly opened the protective shield of the Feitian Palace, completely isolating the extremely hot temperature of the outside world.

Tan Shuangshuang and Tan Feiyu walked forward in the sea of blood mist and sand, cultivating while walking, and their spiritual power was running to resist the heat wave of the outside world stirring up the spiritual energy, and the Flying Palace was slowly moving forward with Tan Shuangshuang and Tan Feiyu's footsteps.

The heat of the sea of blood mist and sand is very strange, whether it is using spiritual power or taking ice crystals outside, it is useless, the blazing breath seems to grow in your flesh and bones, there is nowhere to hide, as long as you breathe and walk on this desert, you can't escape.

At first, Tan Shuangshuang and Tan Feiyu walked very slowly and painfully, and even the bones of the whole person seemed to be hot from the inside out, and the feeling was really bad, and the two of them could only use their spiritual power non-stop to resist this feeling.

Although this spiritual power cannot isolate the heat, when the spiritual power is running, the meridians and bones of the body seem to be strengthened in a slight, and this slightest strengthening will make the body feel a little more comfortable as if it is in an extremely hot hell.

After walking for a long time, seeing that the weather was about to get dark, Tan Shuangshuang and Tan Feiyu entered the Feitian Palace, and sat under the wisteria roses with Lu Tianyi and Bai Sheng Feihu and had a big meal.

After eating, I saw that the sky outside was dark, coupled with the red sand mist that kept stirring in the sea of blood mist and sand, the sea of blood mist and sand at night was pitch black, and the stars and moon in the sky were all covered by the rich blood-colored sand fog, and there was no light.

The cold came quickly to a level that could be felt, the extreme heat in the day was Tan Shuangshuang and Tan Feiyu's cultivation, and the extreme cold at night was Bai Sheng and Feihu's cultivation.

Bai Sheng directly turned into his original form, a huge white tiger with wings on its back like a small mountain, while following the size of the white tiger, the small one was like a plush ball, and the two winged tigers began their cultivation.

Lu Tianyi shuddered, wrapped himself like a ball, and left the Flying Palace together in a trembling manner, accompanied by the Flying Tiger, and cultivated together.

Lu Tianyi's cultivation is not good, he can only walk in the sea of blood mist and sand for a short time to cultivate himself, Lu Tianyi has already cultivated during the day, and at this time he plans to do his best to cultivate for a while at night.

In fact, although Lu Tianyi's cultivation was diligent, he was not too hard, he preferred to do business, but he had stayed with Tan Shuangshuang, a cultivation maniac for a long time, plus Lu Tianyi's admiration for Tan Shuangshuang in his heart, he subconsciously liked to imitate the object of his worship, in addition to the personality of the foodie, now there is also a tendency to become a cultivation maniac.

Originally, Lu Tianyi's cultivation was good to be able to walk in the sea of blood mist and sand for a while, but during the day, he walked stiffly for an hour, and then went down to practice for an hour at night, and when Lu Tianyi was brought to the Flying Palace by Tan Shuangshuang, he was about to freeze.
