The escort fighter plane swept by at a high altitude, and countless bird monsters found the fighter plane and wanted to surround and intercept it, but they were either strafed by the fighter plane and turned into a rain of blood, or they couldn't catch up at all, and watched the fighter disappear into the distance;

The speed of the fighter plane was very fast, the mountains and rivers swept under the soles of his feet one by one, and he flew for about forty minutes, I don't know how far he flew, at this time, Xu Feng's eyes were already a world full of frost;

The speed of the fighter began to decrease, slowly falling, and when the fighter plane got out, he suddenly felt a cold, and a cold wind whistled through, and a thin layer of frost suddenly formed on the surface of Xu Feng's body;

At this time, the place where Xu Feng stood was located on the edge of the southern foot of the Qinghai-Tibet Plateau, in the Himalayas; Xu Feng looked at the vast snowfield under his feet, and the snow-capped mountains in the distance rose one after another, covered with thick snow.

Stepping on the ground, the thick snow covered most of Xu Feng's calves, a cold wind blew, scraping on his body, as if a knife was cutting, taking a deep breath, a faint stream of heat surged through his body from his neck;

The Flame Heart Legendary Necklace on the neck, in such a cold and snowy underground, actually began to emit a faint warm current, which reduced the chill a lot, which was really unexpected;

Xu Feng smiled slightly, put away the fighter, stared at the cold wind, and walked towards the distance step by step;

Before the apocalypse, this was a forbidden area for life, and legend has it that there was a snow monster, and after the apocalypse, it was even more deserted, without the slightest sign of life;

However, after the apocalypse, in this cold ice world, strange monsters appeared, ice monsters formed by the condensation of ice elements all over the body, distributed throughout the Himalayas;

It's just that the level of these ice monsters is not high, only four or five stars, after feeling Xu Feng's breath, they immediately dodged away from afar, the touch of these ice monsters is much sharper than that of humans, even if Xu Feng uses the breathing technique, the breath of his body is like that of ordinary people, he can't fool these monsters condensed by the ice element;

Right now, there is not a single human to be seen here, but it will not be long before it will be overcrowded;

The ice monster here will drop a special ice treasure chest, which can open low-level legendary equipment, but the probability is very low, but there is a lucky guy who accidentally hit it here and hung it in the auction house, because of a special ice attribute, it was guessed by others to come here, therefore, the crowd that swarmed here almost wiped out the ice monster here;

However, Xu Feng didn't come here for the Ice Chest, the chance of it falling was too low, and unless he spent a lot of time farming Ice Monsters here, it would be impossible to hit it;

Xu Feng came here for a special herb, and it is also the herb needed to refine the Breaking Pill, the essence ice ling, this is a herb that Xu Feng finally remembered that he had an impression, this herb had been sold in the auction house in his previous life, although Xu Feng could not afford to buy it, but the appearance of the essence ice cream still remembered;

It was a herb that was almost about to turn into a human form, and its whole body was as crystal clear as ice, as dazzling as crystal, when Xu Feng saw it for the first time, he thought it was a crystal work of art, but he didn't expect it to be an herb;

Xu Feng walked towards the snow-capped mountain range in the distance, he remembered that when the essence ice was auctioned, the auctioneer introduced that he was looking for it in a cave among the highest peaks in the Himalayas, so Xu Feng now needs to move towards the highest peak;

Ordinary people who want to enter the highest peak of the Himalayas need to prepare for at least a few months, and then spend a few months before it is possible to enter, but Xu Feng does not need to spend so much time;

Strong physical fitness, to ensure that Xu Feng in such a cold climate, can also move freely, although a little cold, but not cold to the point that Xu Feng can not bear it, not to mention the legendary necklace around the neck, providing himself with a trace of warmth;

It took three days for Xu Feng to find a crack halfway up the highest mountain;

Looking down, the crack was pitch black, and I didn't know where it led;

It should be here, and there is no other place that can be called a hole;

Xu Feng took a deep breath and bent down into the crack of this cracked mountain cliff;

After entering the cave, his eyes were black, and he couldn't see the situation clearly, but Xu Feng's perception could clearly perceive the scene in the cave, as if he closed his eyes, he also knew how far away the rock wall of the cave on the left was from him, how deep a depression in front of him was, and whether he could step through;

It's a wonderful feeling;

The direction of the cave seemed to be winding down, and after walking for about an hour, Xu Feng vaguely heard the sound of tinkling water in front of him;

"It's amazing that there is still groundwater that has not frozen in such a cold and snowy place!" Xu Feng said secretly in his heart;

Continuing to walk along the cave, I felt a slight chill at the tip of my nose, and the further down I went, the stronger the chill became, and finally I came to the end, and at the exit of the cave in the distance, there was a faint light;

When I came to the end and looked inside, there was an underground cave in front of me, countless icicles were like pagodas, layer by layer and extending upwards, in the middle of countless icicles, an underground river more than three meters wide was flowing happily;

Xu Feng felt it, the temperature here is definitely below zero, I don't know why, this underground river has not frozen yet, it is really a little surprising;

Among the countless icicles, there seemed to be something shiny, and the light was emanating from these countless icicles, maybe some glowing ore, maybe something else, the brightness was not high, but it was enough for Xu Feng to see the surrounding scene clearly;

When he came to the side of the underground river, Xu Feng saw that there were aquatic plants growing in the river, and the whole body was like white jade, like nephrite, which continued to ripple at the bottom of the river with the flow of the river;

Xu Feng stretched out his hand and dragged one up, and found that it was just an ordinary cold ice water grass, a kind of herb that can make cold-resistant medicines, looked at the length of the river, and couldn't see the end at a glance, and this river, all of them are such herbs, if they are all collected, they will also make a small fortune, if it was Xu Feng in the previous life, he would definitely not let go of these cold ice grasses, but now he has a city-level camp, and there will be millions of fate points every day, so he naturally can't look down on these small money, and he will delay time;

Xu Feng looked along the underground river, and there was a light green light in the distance, like a green flame, floating above the underground river;

Such a vision naturally attracted Xu Feng's attention, and he slowly walked along the underground river towards the green flame that was flickering, and after walking a few hundred meters, Xu Feng could already clearly see the green flame;
