After picking up the custom-made winter clothes from Baijie, the three of them did not go back to Nangong Manor, but walked towards the west gate of the Hongjing base.

On the way, Gu Feng received a few messages, clicked on them, but they were sent by Nangong Liuli, asking if he could solve the problem of Lingiron Mine.

He thought about it for a moment, and then agreed, but on the condition that it was two bloodstones, ten four-lock crystal nuclei, and forty three-lock crystal nuclei.

Even the Nangong Consortium, which has been a little weak in recent years, can take out two bloodstones, and there is no reason why the strongest military department can't take it out.

He glanced at the location link sent by Nangong Liuli, one of the two spiritual iron mines was in the northeast of the Hua District, more than a thousand kilometers away, and the other was in the northwest of the Hua District, the distance was even farther, four or five thousand kilometers away.

The distance of more than 1,000 kilometers is still a relatively long distance for Gu Feng yesterday, and now, under the foot power of the Wind God Dragon Sparrow, it is nothing.

Originally, Gu Feng also wanted to take his sister and Xiaolu to visit the Fire Lion Town outside the base, Qin Tianzhu and his wife took Wu Ren to visit the New Year a few years ago, the Fire Lion Mercenary Group had a mission a few days ago, Qin Tianzhu was no longer at home, and today he was still going to see him.

However, it shouldn't take too much time to solve the problem of the two spiritual iron mines.

Thinking of this, he stopped and greeted his sister who was wandering not far away: "Ruoxue, let's go outside to play today, and then go to see Uncle Qin, okay?" ”

"Yes, yes."

"What about you?" Gu Feng gently stroked Xiaolu's hair beside him.

"I can do it all."

After Gu Feng waited for his sister to come over, he summoned a gust of wind to slowly lift the three of them up, and when he came to mid-air, he summoned the dragon sparrow in the sea and flew towards the black ridge in the northeast.

At this time, it is a cold winter, although the sun is shining, but at an altitude of tens of thousands of meters, the cold wind is howling and coming.

Gu Feng opened an energy barrier to isolate the cold wind outside, and ignited another fireball that hung on the barrier to keep warm.

As for the winter coat made of the silver wolf skin of the Five Locks Silver Moon Wolf King, after coming to the sky, Gu Feng asked the two girls to change into it.

Wang Ruoxue was wearing a silver leather jacket, holding a little wolf with a resentful face, and was screaming excitedly.

Her ability is somewhat special, it belongs to the light ability, but it is different from the ordinary light ability that can only heal, her light ability can be turned into light wings to allow her to fly, and can be turned into a light dagger to defend herself or attack. But the bare wings could only allow her to fly at a low altitude, and she flew very slowly, and the extreme speed of flying at an altitude of 10,000 meters made this little girl extremely excited.

In fact, Gu Feng and Xiaolu are not much better, Gu Feng is a little better, after all, he has flown once, and he has a strange sense of steadfastness about his ability. Xiao Lu's little face was slightly pale, and her hands were even more clutched around Gu Feng's arm, and after a while, she was relieved.

In the sky above the Yanshan Mountain Range, a large number of birds and beasts flew by from time to time, some birds and beasts with keen senses noticed this black strange bird with an extremely terrifying breath, and they would avoid it from afar, and some unlucky eggs who couldn't dodge it would be cut into powder by the invisible knife intent all over the dragon bird's body, turning into some extremely fine blood foam, floating in the cold wind in the sky.

Dozens of seconds later, a dark green of the Yanshan Mountain Range at their feet gradually disappeared, replaced by a silvery white, and the abandoned cold city base also came into the eyes of the three of them.

Gu Feng's heart moved slightly, and he controlled the dragon bird to fly downward.

The black dragon sparrow swooped towards the cold city base in a chirping sound, and the current appearance of the cold city base was more and more clearly presented in front of the three of them.

The crumbling walls, the red blood still fresh on the ice and snow, the fragments of mechs on the ground outside the base, and the bleak and desolate streets all emphasize that this is a dead city that has been breached by the demon tide.

The cold and sparsely populated north are not suitable for the growth of flesh and blood nests, so even if the cold city base has been breached for several days, there are still no traces of fungus or meat blankets on the ground and walls, and there are not even a few monsters wandering in the base.

After the dragon sparrow fell from the dome of the mercenary training hall in the center of the base, it was not recovered by Gu Feng, in a sense, this strange creature transformed by the sword spirit had already turned from virtual reality to have its own life.

The dragon sparrow, also known as the god of wind, naturally yearns for freedom, after the three of Gu Feng stepped down from it, it flapped its wings and flew to forage for food.

The earth spirit sleeping in the Yin-Yang Stone had already woken up in the early hours of this morning, turning into a mighty stone man holding a black broadsword and wearing black heavy armor.

Gu Feng released all the seven elemental spirit bodies and earth spirit stone people, and went to the base to look for valuable things, while he took Xiaolu and his sister and flew straight north.

There, there is one of the largest underground bases in Cold City. This underground base, according to his guess, should belong to the military of the Cold City base. Inside the base, it is supposed to be possible to find some blood samples of evolutionary beings.

In a few moments, the three of them came to the edge of a large pit. Of course, the big pit was not formed naturally, but was dug by some huge demonic beasts.

Those demonized beasts still retain an extremely sensitive sensing ability, such as the dog demon's sense of smell. Therefore, it is basically impossible to hide underground to avoid the magic tide.

Below the big pit, there is the underground base, and when you look down the pit from above, you can only see a cylindrical elevator passage, as well as flashing lights in the dark passage from time to time. This scene is quite similar to the plot in some ghost movies.

Wang Ruoxue secretly glanced down, and immediately retracted her little head, she leaned against Gu Feng tightly, and her two hands were even more desperate to hold the silver wolf.

Gu Feng was a little amused, lowered his head and asked, "Are you going down?" If you don't want to go down, you can wait on it, I'll pick up something and come up. ”

The little girl did not speak, but one hand let go of the little wolf and grabbed him by the hem of his clothes.

So, a gust of wind blew and sent the three of them steadily into the underground base.

The base was in chaos, and the security measures had all failed under the ravages of monsters, and under the light of the white light that lit up on Gu Feng's body, the three of them looked at it while walking, and soon walked around the first floor.

No!

Although the area of the first layer is large, there is no trace of blood samples from evolutionary beings.

So through the elevator shaft before, the three of them came to the second floor, and in an office on the second floor, Gu Feng finally had a harvest - a map of the distribution of the underground base.

In the distribution map, on the sixth floor of the underground base, there is a room labeled as a cold room for specimens.

The trio went up the elevator shaft to the sixth floor, and after arriving at the sample cold room, they quickly left the underground base after collecting the eight refrigerators that were still working inside.

On the ground, eight elemental spirits of different colors were already waiting there, and behind them, there were piles of their own harvests,

Although the Hancheng base is only a medium-sized base, the northerners are already bold and warlike, and they have saved some good things in the past few years, and now, these benefits are all owned by Gu Feng.

Four bloodstones, thousands of crystal nuclei of different colors, and more than a dozen alien fruits, as well as tons of spiritual iron ore, were all included in his portable dimension in an instant.

Gu Feng summoned the dragon sparrow that was frolicking in the distance, and the three of them flew north again.
