But the roar was still heard, and the sound of biting prey in the distance suddenly became quiet, followed by a dense grinding sound.

Luo Fei could already imagine how many thick tails were rubbing on the ground.

"Let's go, snake people live in groups, and more will appear if you kill a batch."

The armed mecha pilot named Tian Wa fired a few bullets into the distance, and regardless of whether he missed or not, he immediately turned around and climbed upward.

One of the snake men was shot in the neck and was punched in a bloody hole, and the remaining bullets only hit the stalagmite, shattering large swaths of rubble.

If I had known, I wouldn't have given you so many bullets, and my shooting skills were so poor.

Luo Fei saw that there were not many snake people rushing over, only five, and reflexively shot a few shots at them.

The five bullets were discharged one after the other, but they scattered like scattered flowers, all of which bypassed the stalagmites and accurately hit the heads of each snake man, making a bloody hole in their triangular heads.

Several snake people suddenly froze, and in the next second, they all rushed forward and fell to the ground.

"Hurry up, it's bad if you get tangled in them."

Tian Wa climbed onto a long stalagmite, reflexively stretched out his arm to Luo Fei, and when he saw the situation in front of him, he couldn't help but open his mouth wide in the cockpit.

After a second of silence, Tian Au came back to his senses, "Let's leave quickly, it won't be long before they catch up with us, I can assure you, there are more of them than our bullets." ”

"Where do they all live, why didn't I see them when I first came down?"

Luo Fei grabbed his outstretched hand, jumped slightly, and jumped to a position higher than him, and he was stunned again.

Reflexively, he grabbed his hand and quickly pulled him to the same steps as himself.

"They live in underground caves, and they usually like to fight, but when they encounter an external enemy or something, they will immediately attack the invaders."

Tian Wa explained as he watched Luo Fei climb up with an almost agile figure, and had the energy to reflexively pull him to move quickly.

This couldn't help but make him ask, "You're really good, my driving level is a two-star driver, are you a three-star driver?" No, you're also very good at shooting, is it a four-star? ”

"I don't know, I haven't tested it yet." After Luo Fei's continuous dragging and dragging, the two came to the entrance of the stone crevice at the same speed as they descended.

Carefully probing outside, the red-sucking birds had already flown into the distance, and at this time they could only see a group of small black dots in the sky.

Hiss......

At this time, there was a large number of hissing sounds from the cracks in the stone, the sound was very loud, and the soil on the stone wall was shaking, if Luo Fei was holding a glass in his hand, he might be shattered immediately.

"We'll be fine if we get out of their territory, but watch out of our step."

"Why?"

"Because xenomorph snakemen can burrow into the ground, they will appear at our feet at any time."

The two of them sprang out of the cracks in the stone and ran in the other direction without looking back.

It didn't take long to run, and in the crack of the stone, countless earthy yellow snake people burst out like fountains, and when they saw Luo Fei and the others from a distance, they all screamed and rushed over.

In the gale, it is difficult to maintain balance even in the piloting of an armed mech weighing up to 10 tons, let alone speed up, but the snakes behind them are unexpectedly stable behind them.

"The strength of these guys' solidarity is truly terrifying."

Luo Fei turned around to observe the situation and found that those snake people were all holding hands, connected together, the tail of the one in front and the waist of the one behind were connected, and all the snake people seemed to have become a whole, swaying from side to side like aquatic plants fluttering in the wind.

"How big is the territory of these guys, it seems like they are going to chase for a long time."

After running for a while, Luo Fei found that the other party had no intention of disbanding the team at all.

"About 50 kilometers, or they will return to the territory of other snake people."

Tian Wa explained as he ran hard.

Suddenly, a pair of sharp claws appeared under the ground, grabbing Tian Ao's mecha legs, causing him to lose his balance and fall to the ground on the spot.

Luo Fei noticed the situation behind him, and quickly stopped and asked, "What's wrong, what's wrong?" ”

When he looked around, he didn't see anything else out of the ordinary, not even a raised stone.

"Something tripped me just now, it's probably a xenomorph snake man, you have to be careful."

As soon as Tian Ao's words fell, a thick snake tail was thrown out of the ground behind Luo Fei, and fiercely smashed into the leg of the mecha he was driving, if it was smashed, the leg of the mecha would definitely be scrapped on the spot.

Bang......

As it happens, the magnetic shield has been restored, just in time to block the giant tail that flicked it.

Luo Fei hurriedly looked back, but only saw a thick tail sinking to the ground like a stone in the water, he quickly ran up and stepped on two feet, and found that the ground was still extremely hard.

I wanted to pull it out, but the snake army in the distance was getting closer and closer to them, and Luo Fei could only give up immediately, pulling Tian Au and continuing to run forward.

"What was it just now? Energy Defense Shield? All used for individual soldiers? Tian Au was not nervous about the current situation, but asked in surprise about the magnetic mask that had just appeared.

"Let's go, where is so much nonsense, where is it safe, show the way."

Luo Fei checked left and right to prevent another sneak attack.

Sure enough, it didn't take long for the underground snake man to reappear, and it had learned its lesson and threw its tail directly at Tian Ao.

"Just in time." Luo Fei pulled Tian Au hard, let himself face the snake tail in front of him, shook the fighting rifle with one hand, and fired several shots at the giant tail.

The bullet made several bloody holes in the snake's tail on the spot, and a painful roar came from under the ground.

A triangular snake head poked out of the ground, its earthy yellow eyeballs glowing with red lines, and it stared angrily at the guy who shot at it, only to see that the fighting rifle was already pointed at its head.

Bang...... The bullet cut through an arc.

Its triangular head fell to the ground as green blood spurted from the back of its head, but most of its body remained ground, so much so that it could only be embedded in it.

The battle happened in an instant, Luo Fei's reaction was extremely fast, and he solved the xenomorph snake man in front of him in a blink of an eye, and at this time, Tian Wa had just stood up from the ground.

"The battle is over? You killed it? So fast? ”

There were still countless question marks in his head, and before he could sort out his thoughts, Luo Fei continued to run with him.

Is it time to be in a daze?

Without interference, Luo Fei and the others finally got rid of the pursuit of the snake people and fled to another stone mountain.

"Our stronghold is there, but we'd better keep quiet." Tian Ao's voice became quieter and quieter, as if a little louder would alarm some terrifying creature.

"Snake people?" Luo Fei looked up, and at this time, the wind in the sky was much lighter, and the sun on the clouds shone directly on the earth, covering all the land here with bright white silk veil.

"It's not a snake people, they don't dare to come, but a ...... Stone frogs. Tian Ao in the cockpit showed a trace of fear, and in the end, his voice was almost inaudible.

However, Luo Fei still captured the last two words of the other party, "Stone frog." Luo Fei muttered.

Like the boulder crab, the body of the stone frog is also covered with boulders, as if wearing a body of armor, and when there is no food, they will also eat soil to solve the problem of hunger.

However, unlike the boulder crab, which is a social creature, the stone frog is solitary, but the adult stone frog is much larger than the boulder crab.

At this time, they came to the stone mountain that was said to be their stronghold, Tian Au pointed to the stone mountain in front of him, and whispered: "Shh, be quiet, this stone mountain is the stone frog, it is sleeping now, don't wake it up." ”

"Okay, I got it." Luo Fei followed his low voice and whispered softly.

Although he knew that the stone frog was big, the stone frog in front of him was still beyond his understanding.

The stone mountain in front of you is at least 100 meters wide and 100 meters wide, towering on the plain in a semicircle, and the top is the same as other stone mountains, all of which are towering stalagmites.

Not only is it large, but it is also extremely deceptive, and if you don't know it in advance, you only think it's just a stone mountain.

The two slowly and carefully climbed the stone mountain, bypassing many stalagmites, and a wind cave appeared in front of them, which was a natural cave drilled out by a long period of strong winds.

"Please come in." Tian Au opened the steel round door installed on the entrance of the wind tunnel, Luo Fei walked in, and after walking through a passage several meters long, there was a spacious hall behind, and there were several round doors on the wall of the hall, and it was obvious that there were other rooms in the back.

A steel table was placed in the hall, and several chairs were placed randomly around the table.

The two of them all walked into the hall, Tian Au drove the armed mecha to the corner of the wall, the cockpit opened in a burst of air pressure, and the emaciated young man jumped out of it, sat on a steel chair, picked up the teapot on the table and drank it.

Luo Fei thought about it for a moment, and then drove the armed mecha to stand side by side next to Tian Ao's mecha, jumped out of the cockpit, and sat in front of Tian Ao.

Before he could ask questions, the door of the cave was opened again, and armed mechs walked in from the outside, some with empty hands and some holding a soil worm.

Soil insects are insects that live in the ground, similar in shape to autumn cicadas, but they have no wings, and their food is vitamins in the soil, which is a fairly harmless creature.

In addition to the bitter flesh, it is one of the easiest to find emergency food and grass.

A total of seven armed mechs walked in, and they came to the wall of the hall one after another, and some of them had already opened the cockpit and removed the basin-sized soil worm from the mecha's arm.

Some didn't make any movement, and it wasn't until a long while later that they opened the cockpit, and Luo Fei was surprised to see the tears left in the corners of the other party's eyes.

This is? Luo Fei noticed that everyone's mood was very low, all of them lowered their heads and didn't say a word, or their expressions were in a trance, and until now none of them noticed Luo Fei, a stranger.

According to their habits, they began to take care of themselves, hunting soil insects to stew soil insects, and when the mecha battery ran out, they manually unloaded it and took it to the house to recharge.

"Hey, my battery doesn't drain much, so you don't have to flush it for me." Seeing a big man holding a mechanical plier to remove his mecha battery, Luo Fei immediately spoke up.
