Huo Yuhao himself was huddled behind a mountain bag, and the cold weather had no effect on him. However, looking at the smoke curling in the military camp in the distance, he couldn't help but swallow a mouthful of saliva. In the midst of this ice and snow, if you can drink a sip of hot soup, it will definitely be very enjoyable! This time, I am purely a coolie.

Thinking of this, he couldn't help but smile a little bitterly. But it has come to this, so we can only continue to follow.

Leaning on the mountain rock, Huo Yuhao spread out the map, this map was prepared by him a long time ago, it was not the northern map of the Heavenly Soul Empire, but the northern fine map of the Douluo Continent. It cost him a lot of gold soul coins to get this map. The map itself is made of sheepskin, which is soft and tough enough to last.

After roughly distinguishing it, Huo Yuhao found that on this day's march, the Sun and Moon Empire was still marching in the northeast direction, and then a little further northeast, it was about to reach the border junction of the Heavenly Soul Empire and the Douling Empire. And there, too, has reached the edge of the Far North ice sheet, and it must be colder than here.

The temperature there is not a small problem for ordinary soul masters, can ordinary soldiers really hold on?

While thinking, Huo Yuhao turned around, leaned on the mountain bag and looked in the direction of the Sun Moon Emperor's ** camp in the distance, and at the same time turned on his spiritual detection and scanned the barracks.

Soon he found out some special circumstances, in the ** camp of the Sun and Moon Emperor, there seemed to be something, and the soldiers lined up to receive it, and each of them received two small boxes of things, as well as a cotton coat.

The texture of the cotton clothes looks very good, especially the cotton shoes. It is very thick, and it is very warm when you look at it.

It seems that this Sun and Moon Empire has really been prepared! These soldiers should be good in terms of cold tolerance, and they can't be soldiers specially mobilized by the Sun and Moon Empire from the north of their territory. If that's the case. Coupled with the cotton clothes and shoes that have been prepared for a long time, it should be possible to resist the cold in a short time.

This night, Huo Yuhao spent it in the cold wind.

The next morning, he understood what the two boxes for the soldiers were for.

Each box was the size of a palm and was placed inside the clothes by the soldiers, tightly attached to the underwear and tethered around the waist. After they started marching. Huo Yuhao immediately noticed that the inside of this box exuded a gentle heat, infiltrating the soldiers' bodies and helping them resist the cold of the outside world.

That little box should also be a soul guide. If this is the case, there must be a sealed bottle inside the box. It doesn't take a lot of soul power to maintain the heat, but the volume of the small box, that is, it needs to be recharged once if it lasts for a few days.

However, after thinking about it carefully, Huo Yuhao had to admit the cleverness of others. The army of the Sun and Moon Empire is followed by a powerful group of soul masters. The Fire Phoenix Soul Master Group is full of at least three hundred soul masters, and charging those small bottles doesn't need to consume much soul power at all. As long as the garrison rests at night, each soul master is responsible for charging the sealed milk bottles of some soldiers, and naturally the soul power can be replenished.

Unexpectedly, the Sun and Moon Empire had really developed the soul guide to civilian use. If one day, they can find something instead of a sealed bottle. I'm afraid that the soul guide will really be able to unify the continent. Because at that time, ordinary soldiers will become soul masters, with the attack power of soul masters. Think about it, hundreds of thousands of soul masters appeared on the battlefield, what a terrifying existence it was!

Thinking of this, Huo Yuhao couldn't help but sigh in his heart, shook his head, and reluctantly accepted this fact. It seems that the original Three Kingdoms of the Douluo Continent want to rebel against the Sun and Moon Empire. It is necessary to do something in the near future, otherwise, in less than a hundred years, even if the Sun and Moon Empire does not take the initiative to attack within a hundred years, as the technological advantage becomes more and more obvious. Douluo Continent will eventually become people's meal.

Although I sighed in my heart, the tracking still had to continue. Huo Yuhao still followed the side from a distance, following the army all the way forward, heading towards the northeast of the Heavenly Soul Empire.

As the weather became colder, the marching speed of the Sun and Moon Empire's army also began to decrease, and Huo Yuhao originally expected to be able to reach the place in one day, but it took two full days for the Heavenly Soul Empire's army to finally arrive.

As far as the eye can see, it is covered with snow. The cold wind howled like a knife. In such a cold and snowy place, there is very little moisture in the air, because if there is moisture, it will freeze immediately. The temperature here has reached at least minus 30, and it is even more difficult for ordinary people to survive in this environment.

At this time, it was already close to evening, and the army of the Sun and Moon Empire was encamped again, and this time the camp became more intensive than before. Moreover, Huo Yuhao was surprised to find that the appearance of the camp had also changed.

The tent of the Fire Phoenix Soul Mentor Group, which was originally on the innermost side, was moved to the periphery, lined up in an arc, just facing the cold northwest wind, like a wolf guarding its partner, blocking the coldest cold wind behind, among them, the handsome tent was at the front, and it was immovable under the cold wind.

Other tents are neatly and densely arranged at the back. Only in this arrangement can the heat be retained to the maximum.

The smoke was gone, and the occasional hot steam could be seen rising from some of the large tents, and there was no doubt that the firehead had placed the cooking area inside the room, not outside. Otherwise, it would be too difficult to make a fire in this place where the water is frozen in ice.

Huo Yuhao sighed secretly in his heart, people have a hot soup to drink after a day of freezing! Although he is not afraid of the cold, he has been sleeping in the cold and snow for many days, and this day is really not very comfortable.

However, Huo Yuhao also judged that the Sun Moon Emperor ** team should not be far from the destination. Because they have been traveling in a northwesterly direction, and now they have reached the edge of the Far North, and if they continue inward, they will really enter the Far North.

Huo Yuhao, the land of the extreme north, has really been there, and he is very clear about the bad weather conditions there. In that place, it is absolutely impossible for ordinary people to survive. Even with the thick cotton coat and the soul guide that provides heat.

Even if it is a soul master, it is impossible to go deep if it is not at a certain level. What's more, in the Extreme North Ice Field, there are still a large number of ice-type soul beasts, and with the power of the environment, they are much more powerful than ordinary soul beasts. Once encountering a powerful soul beast group, no matter how strong the Fire Phoenix Soul Master Group is, it will be full of strength. Huo Yuhao vaguely guessed that the reason why this operation was carried out by the Fire Phoenix Soul Master Group was probably related to their ability to excel at fire attributes, although the fire attribute abilities would be greatly limited here, they could also resist the cold to the greatest extent. The more he thought about it, the more Huo Yuhao felt that the army of the Sun and Moon Empire led by the Fire Phoenix Soul Master Group this time did not seem to be here to fight, but rather to achieve some kind of purpose.

A faint light flickered, and Huo Yuhao hid himself in a mountain col while thinking. This is cold and snowy, and he is not good at fire attribute ability, and it is completely impossible to eat hot. However, he also has his way.

Took out a piece of dry food from the storage soul guide, and then put the dry food on his right hand, a strange scene gradually appeared, the originally cold and hard dry food gradually softened in his hand, and then exuded some faint warmth.

In recent days, Huo Yuhao in the extreme north is not a fool, his understanding of the ice element has become more and more profound, especially in terms of temperature control.

A piece of ice, in order to melt, must need a lot of heat, and similarly, a basin of water condensed into ice will also release a lot of heat energy.

Huo Yuhao used this principle to seal the air around him, and then control his blood to coagulate into ice, so that heat energy would naturally be emitted, and this kind of control was not too difficult to dominate with his powerful spiritual power.

However, the dry food is only slightly soft, so you have to eat it quickly. After all, he couldn't let the blood in his palm freeze for too long. It's good to be able to eat it.

Simply solved the dinner, Huo Yuhao was ready to start obvious again. At this moment, he was suddenly surprised to find that there was movement in the army of the Sun and Moon Empire in the distance.

On the side of the Sun and Moon Empire, taking advantage of the night, thick metal pillars appeared around the camp, and some members of the Fire Phoenix Soul Master Group wearing dark red armor were busy. They flew in the air, arranged the iron pillars according to a specific position, and then had a special person drive them into the ground and fix them.

For ordinary people, this kind of work must be completed with the help of large machinery, but it is nothing for the soul master, the soul master himself is a soul master, and he can also use the help of some auxiliary soul guides to do these things freely, and after a while, he has already completed seventy-seven eighty-eight.

Could it be that they have already arrived at the place? Huo Yuhao observed carefully.

Undoubtedly, these metal pillars were brought over with storage soul guides, and it seemed that each pillar was fifty meters long and more than three meters in diameter, and its weight could be imagined. Not only is it brought with a storage soul guide, but it also needs a storage soul guide of a considerable grade to do it.

What are the people of the Sun and Moon Empire going to do? This is their destination? What can they do in a barren far north?

Huo Yuhao was puzzled in his heart, but he could only observe now. At least he was sure of one thing, the Sun and Moon Empire would never go crazy to build a fortress here.

The huge metal pillar weighed at least more than 10,000 catties, and it took the joint efforts of several high-level soul masters to put it in position and install it on the ground. Soon, seven or eight metal pillars were nailed into the ground, each of which was more than thirty meters deep into the ground, leaving only twelve meters outside.
