"E-class protective clothing?" Professor Luo was stunned for a moment, as if he had just woken up from a dream, "Yes, I have D-class protective clothing here, you wait." With that, he hurriedly rummaged through the cabinets, and after a few moments, he took out two sets of D-class protective suits.

Sun Yan raised his eyebrows: "It's still a D-level protective suit, you old man has hidden a lot of good things!"

While speaking, Sun Yan quickly changed into a D-level protective suit, smiled, and showed his snow-white teeth: "Professor Luo, if you have to pay me for the fortress, the design of the 'Perpetual Kinetic Elemental Energy Core' will be exempted." When I bring Sister Mo Ling back, this set of D-class protective clothing, as well as all the fine wine in your collection, will be mine!"

As he spoke, a light breeze came out of his body, and the young man's figure flashed, and he disappeared into the monitoring room, leaving Professor Luo alone, standing in place and stunned.

Stepping on the [Hurricane Step], the light wind surrounded his body, Sun Yan quietly ran outside the house, without stopping, following the edge of the underground camp, silently running into the passage, like a wisp of smoke, his figure disappeared in a flash.

The strong wind was howling in his ears, and the scenery on both sides of the passage was constantly regressing, but Sun Yan's state of mind was becoming more and more quiet, if the sky was clear, it would be as blue as a wash.

Contrary to his mirror-like mood, his blood gradually became hot, and his chest was slightly hot. After a week in the cleaner camp, in order to avoid people's eyes, Sun Yan did not practice at all for 7 days. Now, in the face of the unknown danger that is coming, he feels a little excited.

A moment later, the exit of the passage was faintly in sight, Sun Yan quickened his pace, and the light wind around him intensified and rotated, holding up his entire body and passing lightly.

Suddenly, a snow-white silver light came into view, this was the light of white silver spots, Sun Yan had already narrowed his eyes, and quickly adapted to the illumination of this terrifying light.

Without a protective suit below Class E, the white silver light can ignite it and burn the human body to ashes in the blink of an eye. It is said that after a martial artist breaks through to the seventh-level martial realm, the organs, blood vessels, muscles, and muscles and bones of the whole body will undergo changes beyond evolution, so that they can resist the invasion of various rays in the universe.

As for this kind of white scorching silver spots, it is unknown what kind of realm of martial artists can resist it.

Taking the [Hurricane Step], Sun Yan rushed to the edge of the exit of the passage in a blink of an eye, he hid his body against the rock wall, used his eyesight, and bet forward.

Ahead, about 4,000 meters from the cave entrance, the lighthouse of the cleaners' camp stands. The whole world was silvery white, and you could vaguely see a group of black shadows hovering in mid-air, and occasionally, a black shadow swooped down and slammed into the tower body of the lighthouse, causing the lighthouse to crumble.

Bang bang bang...... , a burst of impact sound faintly came, not because the intensity of the impact was very slight. Instead, under the white and silver spots, even the transmission speed of sound has slowed down to a certain extent.

Leaning against the rock wall, Sun Yan silently observed for 30 seconds, he was estimating the number of these [four-winged iron feather vultures], as well as the flight speed of these ferocious beasts.

"There are more than 60 heads, and the speed of the dive is comparable to the full strength of a sixth-level martial artist, which is quite troublesome!"

Sun Yan frowned, under the lens mask of the protective suit, his face became solemn, and the current situation was quite tricky. In the face of a flock of more than 50 [Four-winged Iron Feather Vultures], it is definitely invincible.

A sixth-level strength beast is much more terrifying than a sixth-level martial artist, especially a vulture-like beast, which is not afraid of death when catching its prey, and is quite difficult to chase. While in the red alert zone of the White Prison Star, Sun Yan once accidentally slipped into the lair of vultures and stole two bird eggs to boil and eat. After eating the bird's eggs, the smell on the body did not dissipate for two days, after that, Sun Yan was chased and killed by a group of vultures for two days and two nights, and now I still have palpitations when I think about it.

The [Four-Winged Iron Feather Vulture] hovering in mid-air at this moment must be more terrifying than those alien beasts on the White Prison Star, allowing Sun Yan to fight such a group of alien beasts alone, and under the illumination of the white scorching silver spots, it is even more dangerous than walking a tightrope on a cliff.

With Sun Yan's character, in normal times, he might really try. However, the first task now is to rescue Mo Ling, how to safely rescue the person and bring him back to the cave, is the top priority.

Watching silently, for a long time, Sun Yan took a deep breath, the cyclone around him slowly dissipated, and the sense of existence of the whole person gradually thinned, until he couldn't feel his breath at all.

If the young man could not be seen with the naked eye, even if others stood face to face, they would not be able to detect Sun Yan's existence.

Holding your breath, this technique is generally only mastered by an eighth-level martial artist. Cultivating to reach the eighth-level martial realm, the meridians of the body, the five internal organs, the skin, flesh, muscles and bones have all been integrated with the inner element, and as a result, the yuan force can communicate with nature, so that the martial artist can present all kinds of incredible abilities.

As for Sun Yan's ability to master this technique in the fourth-level martial realm, it was because of his cultivation of the [Optimus One Pillar Skill], since he cultivated this technique, the inner elements of his body have become more mellow and free, and his understanding of the [Zhenlong Pile] and the true meaning of the four martial arts has also become more and more sophisticated.

Gathering the qi of the whole body, as soon as Sun Yan bent down, he was like an arrow from the string, sticking to the ground, and rushed straight towards the lighthouse.

4000 m ......

3500 m ......

3000 m ......

1000 m ......

100 m ......

When he was less than 100 meters away from the gate of the lighthouse, Sun Yan's forward speed slowed down, and his whole person seemed to be lying on the ground, supporting his body with the index and middle fingers of both hands, and the two fingers kept moving, allowing him to pass over.

The fingers kept moving, and although he was wearing a D-level protective suit, the scorching temperature still came, roasting Sun Yan's fingertips with a faint pain, "Grandma is a bear, if you wear an E-level protective suit, my brother's fingers may be scrapped." ”

The body was like a swimming fish, silently swept to the door of the lighthouse, Sun Yan stuck in front of the door, the corner of his eyes looked into the air, he finally saw the true appearance of the [Four-winged Iron Feather Vulture].

Overhead, several black shadows swooped down and slammed into the alloy walls of the lighthouse, shaking the entire tower from the impact. The head and tail of this vulture are about 8 meters long, and the feathers on the whole body are black-brown as if they were cast from iron juice. Under the white silver spots, the feathers around the body were still dull, completely unaffected by this terrible light.

Its two pairs of wings stretched out, a full 20 meters wide, like a small flying machine, extremely terrifying.

These [four-winged iron feather vultures] swooped down, their sharp claws clasped into the gaps in the alloy walls of the lighthouse, constantly flapping the lighthouse with their wings, and the gray-white beaks pecked at the walls, leaving one depression after another.

Standing below, Sun Yan couldn't help but tremble, if it was just a [Four-winged Iron Feather Vulture], he wouldn't take it to heart. However, there were still dozens of hovering heads of the same kind in mid-air, and if they were accidentally entangled by this group of vultures, and under the irradiation of the white scorching silver spots, it would be really dangerous and abnormal.

Hurriedly retracting his gaze, Sun Yan quietly approached the tower door, pressed the switch on the door, and a holographic projection of a number key popped up.

Seeing this, Sun Yan couldn't help but breathe a sigh of relief, and said secretly: Fortunately, the password device of the door is not broken, otherwise, it would really be hopeless to rescue.

Quickly enter the password, which is what Professor Luo just told Sun Yan. The entrance code of this lighthouse is only known to Mo Ling and Professor Luo, which is also the rule of the Yahuang Foundation.

Brush...... , The door of the lighthouse slid open silently, Sun Yan rushed in, turned around and pressed the button to close, and the door closed immediately. But it was like that, wisps of light smoke had risen from the metal floor inside, and the places illuminated by the white silver spots were twisted and deformed, and there was a sizzling sound.

The metal floor inside the lighthouse is different from the walls forged from D-grade alloy, it is just an ordinary alloy, and it cannot resist the irradiation of white silver spots at all.

Getting up, as soon as Sun Yan turned around, he was stunned, quickly raised his hands, made a gesture of surrender, and shouted: "Sister Mo Ling, it's me, Xiao Yan." ”

Directly facing the elevator entrance of the main gate stood a brown-skinned woman with a double-barreled pulse gun in her hand, her right thumb tightly pressed on the trigger, ready to shoot her target.

A tight-fitting blue-brown leather jacket with a deep collar looming under the peaks, and a pair of plump thighs tightly taut leather pants, exuding a wild style. The only regrettable thing is that this girl has a cross scar on the bridge of her nose, which is a flaw.

This girl is none other than Mo Feng's sister Mo Ling, the leader of the Blade Mountain Cleaner Camp, and the only fourth-level martial artist in the entire camp.

Tightly clasping the trigger of the pulse gun, Mo Ling stared at the person in front of him, his eyes were cold, and he couldn't help but be stunned when he heard the voice, "Xiao Yan?"

Pressing the button of the protective suit and opening the lens mask, Sun Yan smiled and said, "Isn't that me, Sister Mo Ling, I'll come to pick you up." ”

Mo Ling's face changed greatly, and he exclaimed: "Why are you here?" You bastard, do you know how dangerous it is outside the road, and now it's daylight, and you're stain......ed with white and silver spots."

As he was speaking, Mo Ling suddenly came to his senses, immediately picked up the pulse gun, aimed at Sun Yan again, and reprimanded sharply: "Say, who are you? Are you a spy of the JW Alliance? The camouflage defense device of the camp was also destroyed by you, what is your purpose?"

Sun Yan raised his hands again and said helplessly: "Sister Mo Ling, it's really me, Xiao Yan." Professor Luo asked me to come, he made the logo on the protective suit, you should always know him, right?"

As he spoke, he tossed over another set of D-Class suits, which had the word "Four" printed on the armbands. Before, Sun Yan wondered why such a strange number was printed on the protective clothing, but now he understands that this is Professor Luo's real name - Feng Sixi.

Seeing this set of D-class protective clothing, Mo Ling's face softened, and he looked at Sun Yan suspiciously, "You kid, hmph! I'll settle accounts with you when I leave here." "Immediately didn't talk nonsense, just picked up this set of protective clothing and put it on.

Sun Yan smiled and said nothing, Mo Ling's character is like this, not dragging his feet at all. When he first came to the camp a week ago, Mo Ling read his employment contract and sent him to pick up the waste the next moment.

Putting on the D protective suit, Mo Ling checked it, at this time, there was a loud bang outside the wall, the ground continued to tremble, and the entire lighthouse had tilted, apparently deformed by the impact of the [Four-winged Iron Feather Vulture].

Sun Yan praised it: "The lighthouse of our camp, as well as the alloy fortress that holds the garbage of the universe, the consortium has really spent a lot of money, and it is really strong enough." However, our underground camp is probably not one-tenth as strong as a lighthouse. ”
