As expected by the morning wind, the high temperature was followed by the extreme cold.

"Starting at minus 30 degrees and going up to minus 70 degrees, dropping by 5 degrees Celsius every quarter of an hour, are you ready?"

"Of course."

The boy nodded, compared to the high temperature of Baidu, he felt that minus 70 degrees was nothing, as long as he maintained a high-speed exercise, he could always maintain his body temperature.

But when the special training began, he found that things were not as simple as he thought.

In the room, there is not only low temperature, but also cold wind, and this cold wind is extremely humid.

The boy ran as fast as he could, but he was still shivering from the cold.

"No, it's not a way to run like this, the more you run, the colder it gets!" Exercise can generate heat to maintain body temperature, but that is without taking into account the presence of wind.

In a cold wind above level ten, the faster you run, the stronger the wind you will feel.

But if you don't run, your body freezes faster.

In the desperate situation, Morrowind once again thought of "going into the details", starting from the defense of every cell in his body, he didn't believe that he couldn't resist the cold.

After thinking of this method, his divine consciousness once again incarnated into the generals and soldiers who guarded the cell city.

Only this time, the strategy he used was completely different from the last one.

Bitter cold is different from high temperature, it is not a predator, but an intruder.

These two sound similar, but they are not. Marauders are only interested in your resources, and they are like nomads on the steppes, riding fast horses to grab your things; And the intruder, it wants all you have, you and your possessions, it wants it all!

Compared to the marauders, the invaders are even more creepy.

At this moment, the cold turned into a pack of wolves, a pack of thorny ice wolves.

Civilians without any power, even if they take up arms, will not be their opponents. Therefore, as soon as the general gave the order, they hid back in their homes and closed the doors and windows.

The walls of the city were ineffective to the wolves, and they quickly jumped on the walls and came into the city.

However, by this time the streets were empty. Enraged, the manic wolves attacked the human house.

However, after the door was breached, they still found nothing.

Where did all the damn humanity go, and where did their food go?

The wolves searched from house to house, but still did not find half a piece of meat.

They came with hunger, but now they have been busy for most of the day, and they have consumed so much physical strength, and they have not found anything, how can they bear it.

In desperation, they had to retreat first. When they left, the people walked out of the tunnels with joy.

It turned out that the general had the foresight to let them dig tunnels and store grain inside. The entrance to this tunnel is narrow enough for humans only, so even if the thorn ice wolves find the entrance, they won't be able to get in.

Of course, this tunnel is not omnipotent, they can be used to deal with the thorn ice wolf, but it will not work to deal with the flame demon, the demon turned by the high temperature last time can smoke fire, if the people hide in the tunnel, it can let them come out obediently by themselves with a fire and a smoke.

But the Flame Demon also has the shortcomings of the Flame Demon, it is large and bulky, and there is only one, otherwise it would not have been defeated by humans last time.

So, any strategy is different from one thing to another, and you have to be flexible in the face of different enemies. Dealing with the Flame Demon requires the concerted efforts of all people and the courage to break through the cauldron and sink the boat; The opponent's thorn ice wolf pack needs to judge the situation, the enemy advances and retreats, and the enemy retreats and I exit, so that the enemy will decline and exhaust again, and he will begin to disintegrate from the inside.

Mastering the method of dealing with the Flame Demon and the Thorn Ice Wolf means that Morrowind has adapted to the high temperature of Baidu and the extreme cold of minus 70 degrees.

Of course, if the temperature was terrifyingly high or desperately low, it was beyond his ability.

Just imagine, a flame demon or a thorn ice wolf who can trample on the entire city with one foot, what will he deal with? He doesn't have an A-rank ability, nor does he have a weapon like a Super Mountain Cannon.

Qingyin looked at the morning breeze that had been frozen into ice sculptures, and nodded slightly.

She nodded in recognition of the boy, knowing that he had successfully adapted to the low temperature.

Although he was frozen into an ice sculpture, it didn't affect anything, the homeostasis in his body was still very stable, and his breath of life was still endless.

……

"So what's the next training program?" The smile on the boy's face grew even stronger.

He just adapted to Baidu's high temperature and extremely cold weather, and his evolution index on the system has jumped directly from 180 to 600. What he was thinking about now was that if he adapted to a few more extreme environments, would it be very likely that he would directly reach the limit of eight or nine hundred, or even C-level.

"Low oxygen." Qingyin's red lips opened lightly and spit out two words.

"Low oxygen, this is to prepare for the future adaptation to the anaerobic or even vacuum environment, right?!"

"Yes, you guessed it right. We're getting 21 percent oxygen in the air right now, and I'm going to reduce it to 7 percent, two percent per quarter of an hour, so get used to it. ”

"Okay." With the previous two successes, the teenager became more confident.

Since he understands "subtlety", his body's adaptability can be called perverted. With the right approach, he can adapt to any extreme environment.

Oxygen is a key element in the body's metabolism, and without oxygen, the life-sustaining chemical reactions in the body cannot continue.

From a life perspective, a lack of oxygen will not work.

But in this era, A-class perfect evolutionaries can adapt to a completely anaerobic environment.

As for why this is, the current Morrowind does not understand very well. He only knows that his body has that potential, and all he needs to do is find a way to tap into that potential.

After entering the details again, he quietly waited for the enemy this time.

But the sun rises and sets, and the whole day passes, and there is no shadow of half of the enemy.

The general stood on the tower, looking into the distance, his heart beating restlessly.

It seemed that a danger he didn't know was coming.

When night fell, the people breathed a sigh of relief and went home to sleep.

But what should come is always coming......

In the wee hours of the morning, the silence was broken by a loud shout.

"Dead!" The cries rang out in every corner of the city.

Many people wake up from a dream to find that their family members are not breathing, and they have died unconsciously.

Under the cold moon, the general in iron armor was running around, his sword was tightly held in his hand, but he couldn't find the murderer.

"Who the hell is it? What the hell are you going to do! His heart roared weakly, and he really hated the feeling of being so powerful.

This time, their opponents are not marauders, nor invaders, but even more terrifying annihilators! What will be their fate......
