After half a ring, Gu Zhen took the jade bottle where the ice spirit crystal was placed, put all nine small Qingling Pills into it, and handed it to Ye Xing.

Ye Xing poured out three pills, took out a jade bottle and put it away, and returned the jade bottle containing six Qingling Pills to Gu Zhen.

Ye Xing said, "You put it away and set it aside!" We used six snow lotus seeds, and there are three more, and we can refine another furnace, but the adjuvant is gone."

Gu Zhen handed over the latest Danfang and the three snow lotus seeds to Ye Xing's hands, and said, "Master, you put it away, collect all the auxiliary medicines in the future, and then refine it, you will definitely have a way to save the three snow lotus seeds!" ”

Ye Xing nodded, and an extra jade bottle appeared in his hand, and there was also a small ice spirit crystal in the bottle, put the snow lotus seeds in it, and then the two jade bottles disappeared from Ye Xing's hand.

The two of them were not too surprised to see things appear and disappear in Ye Xing's hands, because the two had heard that some special space bags also had this function, but the space bags in their hands needed to be untied, which was a bit troublesome, and the capacity was not very large.

Ye Xing said, "The two are the Supreme Elders of the Xuanyue Sect, you can write a letter to the Holy Sect when you go back, and tell me about the conspiracy of the Tang Dynasty, as for those traitors, there is no evidence, you don't have to ask, they can't make any waves!" ”

The two nodded in agreement, and packed their own things into the space bag.

Gu Zhen asked, "Master, aren't you going back now?" ”

Ye Xing shook his head and said, "I've just been out for three months, and I'm going to go to the extreme west to purchase some cultivation resources, just come to the ice field to have a look, Xuanyue Sect is not too far from here, you go back first, I have already said hello to Qi Ming."

Zi Mei took out a book from her space bag and said, "Elder Ye is safe on the ice field, you still have to be careful, there are some particularly powerful spirit beasts in the North Pole, I have an ancient book in detail, it was written by the predecessors of the Purple Moon Sect, it should be useful to you."

Ye Xing took the ancient book and looked through it slightly, and sure enough, the more detailed introduction to the Arctic ice field in the book was far more detailed than what he had seen in the Li family in Tianjing City, and even the topographic map was available, no wonder the two of them found the place where the snow lotus seeds grew so quickly.

Gu Zhen also took out a book, but it was newly copied, and said, "Master, this is thousands of years ago, the predecessors of the Elixir Sect were in the Arctic Ice Field, and got a topographic map of the 10,000-year-old ice marrow, there is a detailed introduction, if you stay for a long time, go and find it, that thing is not an ice spirit crystal, but it is definitely a good thing."

Ye Xing was not polite, he also took it, took a brief look, put it in the space ring, and said, "The two elders will go back first, I will explore the north for a few more days, if there is no gain, go to the western capital of Dayuan, it should not be so quick to return to the sect."

The two nodded, and Zi Mei said, "Elder Ye is careful on the road, take care!" ”

The two of them hung the space bag on their waists, jumped up, and disappeared into the snow in an instant, and the two figures headed south.

Ye Xing waved his hand in the direction of the two, picked up the compass, and gently stretched his body, and the whole person floated up and swept in the direction of the north.

With the cultivation of the two of them, they can return to the Xuanyue Sect in the prairie in about twenty days, everything is arranged, Qi Ming is a personal essence, everything will be arranged.

The cultivation of the second layer of the two Jindan Realm, as well as the spirit weapon gun, as well as the guns of the Xuanyue Sect, the Xuanyue Sect is as stable as a rock, and Ye Xing is more at ease to go out.

The sky was still extremely dazzling, the ground was still white, Ye Xing walked and walked, he was tired, and he walked more and more slowly, and finally came to a big tree.

Stopping to rest, Ye Xing took out the ancient book given by Zimei Dao Chang, took out some water and food, and read it while eating.

This is a handwritten notebook, which records the experience of the ancestors of the Purple Moon Sect in the Arctic Ice Field, and talks about the experience of this Purple Moon Sect predecessor more than 2,000 years ago, who went to the Arctic Ice Sheet to find resources because of the lack of cultivation resources.

This Purple Moon Sect senior was a master of the first level of the Yuan Infant Realm, and he thought that there was nothing in the world that could threaten his existence, so he traveled to the Endless Ice Ocean in the north of the Arctic Ice Field, and he also went through great hardships, and he had been to the northern edge of the Arctic Ice Field.

This predecessor was a man of heart, and he described the very terrain and landforms along the way, and all kinds of observations, and many important discoveries were recorded in the book.

According to the account of this predecessor, the endless ice ocean should be thousands of miles away from here, where there is a blue ocean without ice, and it is also endless, but the temperature of the sea is extremely cold, twice as cold as the current temperature on the ice sheet.

There is no living thing in the blue ocean over there, and the water will not freeze because it is too cold, and the senior who stayed by the ocean for a moment and then left immediately, with his cultivation in the Yuan Infant Realm, he didn't dare to stay in an extremely cold place for too long.

The so-called extremely cold ocean that does not freeze, Ye Xing has quite good knowledge, but he understands that it is super-cold water, that is, due to the extreme cold in an instant, the water does not have time to freeze.

That is to say, the ocean north of the Arctic ice sheet is actually a very special physical phenomenon because it has experienced extreme cold for a moment, and the entire ocean has turned into icy seawater instead of freezing.

Ye Xing also learned from his notes that the 10,000-year-old ice pith is a kind of earth-attribute spiritual liquid formed by the condensation of spiritual energy caused by extreme cold, which is of course extremely precious, but in essence, it is a mutated earth-attribute spirit, and Ye Xing's earth spirit crystals have it, so he doesn't care too much.

The senior also recorded that when he went, he didn't find anything along the way, but on the shore of the extremely cold ice ocean, he found two transparent spiritual insects, both of which were about the size of a little finger, and looked like six-legged insects, which was extremely strange.

One of the snow-colored insects, will spit silk, he named it the ice silkworm, because this insect will secrete a kind of silk, water and fire are not invasive, the knife is constantly chopping, he collected some transparent and colorless ice silk, and then used it to make a spiritual weapon - invisible rope, which is extremely useful.

He brought back a few ice silkworms, but soon after leaving the ice ocean, they were still on the Arctic ice field, and they died, and they should only survive on the edge of the ice ocean.

Another kind of small insect, the pole is like a small bear beast, it is also an ordinary water and fire invulnerable, the knife is constantly chopping, and it is very strange that he does not eat or drink at all, he named it the Ice Bear Insect, because he didn't see any use at all, he brought back two of them and put them in the library of the Purple Moon Sect, but he has been sleeping for decades, and there has been no movement.

Ye Xing has extremely strong and extensive knowledge, knowing that in the vast universe, there are countless types and forms of life, these two kinds of life that are resistant to extreme cold and high temperatures, in fact, there are also life on the earth, submarine volcanoes, thousands of degrees of high temperature and high pressure, those animals are dormant, can go hundreds or even thousands of years without eating or drinking.

Ye Xing was too surprised to see it, in fact, the extreme environment of this world is worse than that on the ball, and it is possible that there are extreme lives in extreme environments.

If the whole ocean is too cold and icy, he has never heard of it, and as for the current minus 98 degrees on the Arctic ice sheet, if it is twice as cold, it will be about minus 200 degrees.

And life in this world is even more extreme and tenacious than on Earth, and it is not surprising to think that there are some extreme life forms.

Ye Xing has dissected thousands of creatures, and also used optical microscopes and electron microscopes to analyze, and he has a considerable understanding of the subtle structure of countless creatures, and he once guessed that life in this world is not only carbon-based, but also likely silicon-based.

According to Ye Xing's knowledge, the temperature range of silicon-based life is much wider than that of carbon-based life on Earth, such as life on Earth, generally living within plus or minus 100 degrees Celsius, and now it seems that the ordinary living temperature of life in this world is between plus or minus 200 degrees.

Of course, due to the different air pressures, it can't be simply compared in practice, but it is obvious that there are a large number of high-level monks and powerful spirit beasts in this world, and their living range is indeed relatively wide.

Although this knowledge is extremely complicated, Ye Xing has a large amount of knowledge reserves, and after a little thought, he quickly figured out the truth.

Ye Xing thought about it, he wanted to retreat a little, he was really a little afraid, he didn't think that he could withstand that extreme cold, in fact, after walking for a few more days, his extremely inspired spiritual sense had already noticed that the climate temperature was slowly dropping.

Although the temperature drop is not obvious, there is still a downward trend, I believe that after walking for hundreds of miles, it will be obvious, to the northern ocean of the ice field, it is really possible to minus 200 degrees.

Ye Xing didn't know what the limit of how low temperature he could tolerate, and he could resist this extreme low temperature for the time being, so after thinking for a while, he decided to continue walking north for a while, and if he really couldn't stand it, he would return immediately.
