The advancement of cultivation is extremely slow, and the main key point is the strength of the human brain's comprehension and divine consciousness, and it is also necessary to add extremely important resources, aura, elixir and exercises, with the fusion of essence and blood.

However, Ye Xing possessed all these qualities, but he still entered the realm very slowly, and he retreated for half a year before entering the late stage of the sixth layer of qi refining.

In fact, Ye Xing didn't know at all that his cultivation speed was already unprecedentedly fast, because even if he was a powerful genius, the advance level was counted in ten years.

And it has been less than 6 years since Ye Xing got the "Ethereal Spirit Sutra" from the black evil, and now he is only 23 years old, and he has already cultivated to the sixth level of qi refining, and he is already a genius among geniuses.

And Ye Xing was dissatisfied with himself because he didn't understand, he didn't know, just because of the lack of cultivation resources, more than 80% of the cultivators had been stuck, and the lack of qualifications made the progress of the remaining 10% or more cultivators slow, and the reason for the exercises also made the remaining more than 9% of the cultivators extremely depressed.

Ye Xing is actually making rapid progress in the cultivation realm now, and he is also practicing martial arts, and he has also reached the highest level of innate knowledge, this is because his divine sense and understanding surpass ordinary people too much, and with the cooperation of exercises and resources, everything is for a reason.

When Ye Xing came out, the three of them had been out for many days, and the three of them began to practice martial arts, because they had obtained the right skills from the remnants of the previous dynasty, and the three of them were also very fun to fight, compared to the boring and long-term meditation of cultivation, it was much more interesting.

Moreover, cultivation pays special attention to imitating nature, and when cultivation reaches a certain stage, it is necessary to rest for a period of time, and it is completely impossible to force it, and there will be no progress.

Ye Xing greeted the three of them, hugged the two birds again, and then took out all kinds of food, and asked Qi Ming to open the pot and open a big meal, penance is really too hard, and you still have to indulge it from time to time.

After a delicious meal, everyone introduced their own cultivation, and they all practiced the cultivation method of the "Taixu Imperial Spirit Sutra", but the details were not the same, because each person's qualifications and spiritual roots were different.

Ye Xing's superiority lies in his analytical ability that surpasses everyone else, and with the enhancement of his cultivation skills, his analytical ability is also rapidly increasing.

After analyzing some of their respective problems for the three of them, the three of them were surprised to find that Ye Xing was completely aware of their problems, and they all had corresponding methods to deal with them.

After staying in the Death Valley for a few more days, the four of them recovered their mental and physical strength, packed up everything, and because they were afraid that the balloon would be scratched by the jagged rocks, the four of them took up the light work and went up to the top of the mountain quite easily.

Ye Xing couldn't help but annotate this location on the map, and now there were several places on the map that he had annotated, deserted cities, oases, death valleys, and several iconic terrains seen in the sky.

For the trip to Mobei, the four of them don't care too much about it now, because they have learned all the ancient characters of the previous dynasty, and there are not too many obstacles to studying the "Taixu Imperial Spirit Sutra", of course, if you can go to the place where the sect of the Taixu Sect is located, maybe there will be greater gains, but it doesn't matter if you don't.

The hot air balloon flies, and the four and two birds sit on the gondola to fight the cold with turtle breath.

Anyway, the direction was to drift north, so I didn't pay any more attention, the internal strength of the four people rose to a higher level, and they had the ability to breathe in the skin and made greater progress, and they actually drifted at an extremely high altitude for two days, until the two bird divine senses told Ye Xing that they were very hungry, so they fell to the ground.

Ye Xing estimated that this drift was at least thousands of miles, and it might not take long to reach Mobei.

The four of them packed the balloons, set up the tent, and then began to make food, of course, to satisfy the appetite of the two birds first, and then the four of them also had a hearty meal.

Counting up, it has been six months since they escaped from the oasis, and it has been almost a year since they were counted from Songcheng, and the four of them now understand the terrifying vastness of the desert, and now it should be summer, but there is still yellow sand and snow here, and it is certain that they are about to enter Mobei.

It is said that Mobei is permafrost, there are no four seasons, only when the south is summer, there is no cold wind here, that is, there will be a period of temperature stability.

The temperature will be stable for two or three months, and it is at this time that you can enter Mobei, according to those remnants of the previous dynasty, Mobei is actually a cold wasteland, in fact, there is nothing special.

At other times, because of the extreme cold and snow, you really don't have to look for anything, it's completely snowy, and it's completely impossible to check anything.

The four of them set up camp tents in the yellow sand pile and rested for two days, and then continued to set off, still flying in hot air balloons at high altitude.

It is also because during this period of calm weather, the hot air balloon can fly north without flying too high, so you can have a panoramic view of the scenery on the ground.

In the land of yellow sand, there are actually endless rolling mountains, as well as many oases and valleys of the green of life.

Legend has it that there are countless kinds of rare medicinal materials and all kinds of strange and powerful insects and beasts in the desert, as well as unknown races, but after the last time Ye Xing was forced to join the tribe, they were no longer willing to come into contact with those unknown forces and races.

As long as they saw the oasis in the telescope, the four of them quickly raised or changed direction, so maybe other people or animals saw the balloon in the sky and didn't pay much attention to it, because it was too small and inconspicuous.

Of course, even if the master saw it, the extremely high altitude was not a height that the monk could reach, and except for surprise, it could not pose any threat to the four of them.

Each time I flew high in the air for a day or two, and then rested on the ground for two days, so that after more than ten days, I really entered Mobei.

Ye Xing is determined by the ice on the surface, under the telescope, there is no yellow sand at all, it is all frozen soil, there is a little moss and very few animals, then this is Mobei.

Mobei is not a desert, and although the temperature is extremely low, it is vibrant, because there are infinite lives that have adapted to the temperature here, as long as there is water, life is everywhere.

Plants are coniferous, and there are endless kinds of animals suitable for low temperatures.

Mobei is under the control of the Great Yuan Empire, but due to the extreme low temperature, it is actually thousands of miles away, but it is not a forbidden area for humans, but there are just too few people.

The super force of the Great Yuan Empire forcibly occupied this place three thousand years ago, just saying that this was his territory, but there was no garrison, let alone development, just let it be like this. Of course, who would want to come here in this difficult place?

But because of the permafrost, countless amazing plants and animals that grow, and all kinds of resources that are not explored at all, this is actually a real treasure trove.

According to the description of Taixu Mountain in the "Taixu Imperial Spirit Sutra", it should be in the center of Mobei, and it is actually a paradise outside the world, because it is actually located in the inner part of the surrounding high mountains, and there is the warmth of geothermal heat, and the inside is more than the south of the Song Dynasty Four seasons like spring, it is a real paradise on earth.

But it's really not that easy to find, and because I'm tired, it's impossible to be in the air all the time, looking at a large flat area in front of me, and countless animals on the ground are moving, the four of them also have a little expectation.

Ye Xing decided to go down to the ground first, because he was familiar with the environment here, or he was also tired from high altitude, so he needed to rest first.

Falling from a high altitude to the ground, it caused the nearby animals to be frightened, and they actually ran, and those long-haired animals, I don't know what kind they were, actually ran up together in hundreds, roaring, extremely heavy and shocking.

The four of them put away the hot air balloon and start wandering around the neighborhood to find a place where they can spend the night.

There are no tall plants here, but there are countless small plants, and there are countless animals that live on the frozen ground, and they are still very large, which is really amazing.

Soon, Qin Jingxuan discovered a variety of medicinal materials mentioned in medical books, which were not found in other places, and they actually grew in conspicuous places here.

Qin Jingxuan explained the method of collection, and Qin Xinyue and Qi Ming immediately moved to collect the medicinal materials that could be seen nearby.

Ye Xing carried out his own divine sense to scan the vicinity, and also let the two eagles observe in the air what is suitable for living.

Soon, under the instructions of the two eagles, Ye Xing came to a rocky slope a few miles away, and after turning around, he picked a leeward place, not a big place, but very flat.

Ye Xing took out the camp tent, and then began to build it, because there is a special mechanism design, it is basically unfolded at once, so it doesn't take much effort at all, mainly the corners and edges can be added with fixed drawstrings.

An hour later, when the three of them returned to the camp with the two birds, Ye Xing had already prepared the food.
