The depleted riverbed has long been occupied by yellow sand, and the rolling sand dunes are like countless graves, echoing the ruined city with collapsed walls and collapsed houses.

But there were a lot of holes in the wide riverbed.

Countless sandworms broke through the ground one after another, the small ones were like gray pythons more than ten meters long, and the large ones were like a series of biological trains, surging towards the four humans like rivers and seas.

"Ah! The sandworm is out, run......

Tian Xiaobei exclaimed in surprise and turned his head and fled, and the Qin family sisters also chased after them in a panic, they had long heard of the terrifying big sandworm, but they knew how shocking it was after seeing it with their own eyes.

"Don't run around, go back to the bunker where the flag was planted......

Cheng Yifei ran to the helicopter with a rifle, and the helicopter that was damaged by the forced landing was crooked in the sand dunes, but half of the skeleton was left more than ten meters away, obviously half corroded by acid.

"Boom~~~"

A huge sandworm suddenly stood up, enough to devour the vehicle's large mouth with fangs, but it spewed out a large stream of acid from a distance of hundreds of meters, like a fire hose.

"Tong~"

Cheng Yifei slammed the lance into the sand, jumped into the cockpit at the same time, and pulled the deformed hatch shut.

"Wow~~"

The green acid sprayed onto the fuselage, and a strong pungent smell hit the nose, and puffs of white smoke came out of the fuselage, but it failed to burn through the helicopter's shell.

"Hide! Don't come out ......."

Cheng Yifei squatted in the cabin and pulled off his coat, and took out a black corpse crystal from his inner pocket, which he found from "Listen to the Wind", which could kill all the little zombies that were close to him.

But he's not sure if the corpse crystal will be able to kill the sandworm, which doesn't seem to be an undead creature.

"Boom, boom, boom......"

Large and small sandworms surrounded from all sides, and a rough count of them probably exceeded thousands, but just as he estimated, the swarm of insects stopped when it approached a certain range.

"Haha~ That's right! This is the real no-go zone......

Cheng Yifei got up from the cabin excitedly, sandworms are freaks that can even digest the land, and there is only one possibility if they keep the corpses and don't eat them, they don't dare or can't get close here.

Cheng Yifei held the black corpse crystal tightly and looked around.

The nearest sandworm was hundreds of meters away from him, and the farthest foot was hundreds of meters away, and the swarm of insects enclosed a large circular area.

However, they are not in the center of the forbidden area, and the distance should be in the deserted urban area.

The diameter of the forbidden area is not less than a thousand meters, but the attack range of the sandworms is not small, if they want to rush to the center point, I am afraid that they will be sprayed with scum halfway.

Who knew that the insects did not continue to attack, but lay on the ground and did not move.

"Huh? You can't be blind, are you......

Cheng Yifei knocked on the cabin a few times in surprise, and sure enough, the situation changed suddenly in the next second, and hundreds of acids sprayed towards him, wrapping the helicopter in a sloppy manner.

After a moment of silence, the sandworms lay back on their stomachs and did not move.

Cheng Yifei gently opened the smoking hatch, picked up a few tin cans and threw them out one after another, and the nearest sandworms immediately turned around and sprayed acid directly at several cans.

"Xiaobei! They are blind, and I will lead them away......

Cheng Yifei suddenly kicked the hatch out, turned it out and pulled out the lance, and then picked up the hatch on his back, and ran to the center point at a speed of 100 meters.

"Puff puff ......"

Hundreds of sandworms spewed acid frantically, but fortunately, his own skills were not affected, and his speed was much faster than normal, and the hatch could also help him block the deadly attack.

"Boom~~"

One of the longest big sandworms stood up again, and suddenly spewed out a large mouthful of fangs, and Cheng Yifei, who was shocked, hurriedly used the Wind Shadow Sword Technique, and the full internal force instantly burst out from under his feet.

"Knock~~"

Cheng Yifei threw away the hatch and shot into the air, like

A shell that came out of its disembowelment shot out dozens of meters away, and it landed on the river embankment in danger and danger.

"Papapa......

The dense fangs tore through the discarded hatch and covered the dunes like a torrential rain, but the other large sandworms followed suit.

"Come on! Come all here......

Cheng Yifei, who kept moving in a serpentine position, shouted, but seeing that the ruined city was close in front of him, he suddenly threw a poisonous bone lance that was in the way, and jumped over a broken wall and lay on the ground.

"Bang Bang Bang ......"

The fangs hit the broken wall like a machine, and the gravel smashed his head and face, but fortunately he was lying under the strongest wall, and the sharp fangs were stuck in the wall.

"Whew~ Your grandmother's, fortunately there is a wall......

Cheng Yifei raised his head with palpitations and saw that many small sandworms had already burrowed back into the burrows, and the rest also rushed towards him, revealing a big gap in the encirclement.

"Xiaobei! Leave me alone, and climb out when the time comes......

Cheng Yifei shouted twice and got up and ran wildly, and the insects chased him and kept spraying fangs, but he didn't forget an old friend in the forbidden area, even if he held the black corpse crystal, he didn't dare to use it.

The deserted urban area is covered with only a thin layer of sand, and some of the buildings remain in a dusty state.

Cheng Yifei crawled and hid in the ruins, and finally exceeded the attack range of the big sandworms, but the center point was a collapsed shopping mall, and not even a small zombie could be seen around.

"Damn! This is a......

Cheng Yifei panted and bent over closer, he didn't know how big the volume of the source crystal was, if it was just a fist-sized crystal, he might not be able to find it after digging it alone for half a year.

Suddenly! A complete roller shutter comes into view.

The entrance to the underground garage was not damaged, and he immediately ran over with a poisonous bone lance, and split the roller shutter door with a few clicks.

The underground car park was pitch black, and a large number of private cars were neatly parked in it.

Cheng Yifei cautiously got in, the night vision eyes could give him a clear insight into everything, and he couldn't smell a trace of corpse odor, which made his tense nerves relax a little.

"Wow~~"

The cracked roof continued to have yellow sand flowing down, and Cheng Yifei, who was looking around, did not notice that the yellow sand that flowed down gradually condensed into a human shape.

Suddenly!

A row of barefoot footprints appeared in front of him, stretching straight to the entrance to the second basement floor, and the small feet were clearly a child or a woman, which immediately reminded him of Amanda, the sand girl.

"Jiang Sanmei! You're not looking for the source crystal, are you......

Cheng Yifei touched the black corpse crystal in his pocket, and slowly walked into the entrance of the second floor with the courage to go, but after going around the turnaround lane twice, he suddenly covered his mouth and nose in front of the exit.

It's all people!

The second basement floor of the Black Hole Cave is densely populated with human figures, and countless sandmen occupy the entire basement.

The sandman's whole body was covered with heavy yellow sand, and he couldn't tell whether it was a corpse or a zombie inside, but he turned his back to him without moving, and there were tens of thousands of shoulders one after another.

'Jiang Sanmei!!

Cheng Yifei, who was secretly screaming, almost shouted, only to see a sand girl suspended in the deepest part, her arms outstretched and her back facing the sky, which was still the center point of attention of all the sand people.

"Huh~~"

The sand girl opened her eyes coldly, and two terrifying blood lights bloomed in her eyes.

The blood light not only shot straight at Cheng Yifei in front of the exit, but tens of thousands of sandmen also turned their heads in unison, and the yellow sand on their bodies rolled down.

"Haha~ Jiang Sanmei! An old friend has come to visit you, and I'm not surprised......

Cheng Yifei took two steps forward with an embarrassed laugh, and finally saw a spar the size of a car lying on the ground where the sand girl was suspended, but the transparent state did not have any color.

"Roar~~~"

The sand girl suddenly let out a roar, and tens of thousands of sand men rushed out, and all kinds of things appeared in their hands in an instant

Yellow sand weapons, and the yellow sand all over the body was quickly transformed into armor.

"Amanda! It's my ......."

Cheng Yifei hurriedly pulled out the starting lance, and the energetic qigong wave hit a group of urgent pioneers, but the one-sided scene did not appear, and it was actually blocked by the sandmen raising their knives.

"it!"

Cheng Yifei was shocked and retreated and wanted to run, but there was also a rumbling sound from the exit, only to see a large number of sandmen rushing down, and actually blocked his retreat.

"Jiang Sanmei! I'm Cheng Yifei, don't mess around......

Cheng Yifei hurriedly fled to the side with a roar, who knew that the sand girl had already denied her six relatives, and waved her hand to shoot out a large piece of sharp sand cones, crackling and piercing the vehicle.

"Little ***! This is the ...... you forced me."

Cheng Yifei hid behind the pillar with a roll, took out the black corpse crystal in his pocket and threw it into the air, and then slashed it fiercely, smashing the green to black corpse crystal in the air.

"Boom~~"

A dazzling green light swept across the basement, and the swarming sandmen froze in unison, clattering and shattering like porcelain.

The sandmen were scattered into pools of yellow sand, but there was nothing in the sand.

"Knock~~"

Cheng Yifei was also blown out by the explosion, and the red crystal in his body instantly propped up the light shield, protecting him and smashing him on a BMW, and at the same time, half of it was stabbed out of his chest.

"Isn't it?"

Cheng Yifei suddenly looked ahead in surprise, the sand girl actually stood firmly on the ground, but she peeled off the yellow sand to reveal her true body, it was Amanda who committed suicide by jumping off the bridge.

"You, you shouldn't come, it wants yours, power ......"

The sand girl suddenly stumbled to speak, her hoarse voice was like an iron sheet rubbing, and its struggling expression was like fighting against something, and then she raised her right hand tremblingly.

"Strength?"

Cheng Yifei covered the red crystal on his chest in surprise, and immediately felt a strong suction, and actually wanted to suck the red crystal in his body.

"Let's go! It's devouring my ......."

The sand girl shouted out very urgently, but Cheng Yifei was as if he had been poured lead, his body was so heavy that he couldn't move a bit, so he could only desperately hold the red crystal to not be sucked away.

"Ah~~~"

The sand girl suddenly raised her head and screamed, its consciousness seemed to be swallowed up at once, not only did its expression of resistance become numb, but the suction in its hand also increased dramatically.

"Ah!!h

Cheng Yifei couldn't help screaming, feeling that all his internal organs were going to be ripped away, until Hongjing burst out with a bang, and his heavy body suddenly recovered.

"Wow~"

The fist-sized red crystal floated into the air and flew straight towards the sand girl's hand, and the sand girl's eyes also became emerald green, revealing a greedy and eager look.

"Die!"

Cheng Yifei suddenly roared and jumped up, and the lance in his hand slammed down, and it slammed into the red crystal.

"No !!"

The sand girl let out a panicked scream, and the red crystal also exploded between the two sides, letting out an earth-shattering and terrifying explosion......
