Snake Mountain, inside the cave.

In the deep darkness, there was a faint light, reflecting four bleak faces.

And the phone is running out of battery.

There are only four people left in the archaeological team, Hao Jianguo, Bai Hongfei, Tong Wei, and the only girl in the team, Xie Baimeng.

Except for Hao Jianguo, who is the team leader, the other three are all young people who have not been deeply involved in the world, and they suddenly encountered a big disaster, so they were naturally all in chaos, and people were panicked.

The cave was silent, only Xie Baimeng's low sobs echoed, adding to the oppressive atmosphere.

"Bai Meng, rest assured, the distress signal has been sent, and rescue may arrive at any time. Bai Hongfei said comfortingly, and his tone was firm.

"Hmm!" Xie Baimeng stopped sobbing and nodded.

Her thoughts were swirling.

Sure enough, it is the wind that knows the strength of the grass, at this moment, Tong Wei, who can speak well on weekdays, has shrunk into a ball, but it is the taciturn Bai Hongfei who is more reliable.

"A distress signal?" Tong Wei looked desperate, his expression didn't know whether to cry or laugh, "In such a barren mountain and wilderness, can the signal be transmitted? Even if it is transmitted, it is the season when the beast tide is out, can the rescue team rush over?"

He asked questions again and again, each of which made the atmosphere in the cave more and more depressing.

Bai Hongfei and Xie Baimeng were silent, while Hao Jianguo was holding a clay pot and still didn't say a word.

"It's all your fault!" Tong Wei's fear turned into rage, and he scolded Hao Jianguo, "The guide reminded me several times, you can't dig at this time, you just don't listen! It's you, it's you who killed Zhang Hong, you killed Jia Sanchuan, you killed Chen Guangjian, and now, you want us to accompany you to wait for death slowly!"

Hao Jianguo was silent, but his hand holding the clay pot tightened a little.

"You're dying, and you're still holding that ghost thing and not letting go?" Tong Wei looked fierce and said viciously, "What, you want it to be buried with you?"

"In this burial object, it is likely to be the 'real dragon bone molt' in the ancient records!" Hao Jianguo said with a solemn expression and meticulousness, "Once the excavation is successful, it may be a milestone in archaeology and even biology." ”

"Milestone? and the excavation was successful?" When the shadow of death came, Tong Wei was already hysterical, "Is it an excavation now? It is clearly a burial! Also, we all have to bury it!"

He jumped like thunder, suddenly viciously to the side of the guts, snatched the pottery from Hao Jianguo's hand, and held it high above his head.

"I see, this thing caused the collapse! It's hoodoo, look at me smashing it!"

Boom!

The pottery shattered, and a bone fell out and tumbled.

The bones seemed to be decayed, covered with jasmine veins, and in the darkness they shone like fireflies.

"Break it for Lao Tzu!" Tong Wei laughed cruelly, raised his right foot, and stepped on it fiercely.

"No!"

Hao Jianguo pounced, hugged Tong Wei's right leg, and scuffled with him, Bai Hongfei hurriedly stopped, Xie Baimeng kept begging the two to stop, and the scene was almost out of control for a while.

Rumble!

A violent concussion struck, and the three of them fell to the ground unsteadily.

"What's going on?" Bai Hongfei looked left and right, his face panicked.

......

"Huh?"

Outside the cave, the four mecha planes seemed to have been immobilized, and they didn't dare to move.

"Captain, what's going on?" Wang Ru looked at the top of his head, with a worried look on his face, "Could it be that we destroyed the mountain and rock structure and caused the second collapse?"

The collapse is not a trivial matter, and if you are not careful, the four mechs will have to be buried inside.

"It's not. ”

Su Yunhan listened attentively, his fingers tapped continuously, and a radar shadow floated beside him, and there were red light spots flashing in the shadow, warning him.

"The vibration came from the ground, and it was a ...... Beast Marshal!" she paused and said in a deep voice.

Now, the arsenal and the omen's pupil have merged, and Su Yunhan's vision has added a picture from the phased array radar.

Phased array radar is so powerful that it can not only peek in all directions, but even survey the depths of the earth! Not only that, it can also detect heat sources and accurately determine the level of the giant beast through the heat radiated by the mechanical beast's body.

Therefore, the beast was still hundreds of meters away, and Su Yunhan was already watching the fire.

"Where is the beast handsome?" Meng Lei looked vigilant and looked around.

"Underground, about 30 degrees west-north, 800 meters away. Su Yunhan's expression was solemn, and he said in a low voice, "Judging from the excavation route, the target is the archaeological team!"

"West-north?" Zeng Zishi listened, speechless, "so accurate?"

"What?" Meng Lei looked suspicious and puzzled, "The archaeological team only has a few taels of meat, how can it attract a beast handsome?"

"Who knows?" Su Yunhan was also puzzled, shrugged his shoulders and said, "Fortunately, its speed is relatively slow, and it will take about five minutes to reach ......"

"What about slowness?" Zeng Zishi smiled bitterly, "It's underground, can we dig through it?"

"Captain, can you speed up the excavation of the passage and let the archaeological team come out?" Wang Ru proposed.

"Difficult!" Su Yunhan shook his head, "According to the current progress, it will take at least three minutes to dig up the mountain rocks, and there are too many variables......"

"What can I do then?" Wang Ru grimaced.

"Lure it out and fight!" Su Yunhan's eyes lit up, and he said in a deep voice, "Get ready for the 'flowing crossbow', charge it up, once it comes out, don't hesitate, attack immediately!"

"How to lead it?" Wang Rugang wanted to ask, but Wu Qu had already done it.

Airplanes!

As soon as Wu Qu raised his hand, a metal disc floated in the air, its surface hummed and trembled, and there were magnetic storm ripples overflowing, like bursts of water waves, rippling out, and it took a long time to disperse.

"Huh?"

Exclamations rang out, and the three assault battalions retreated at the same time.

The disc had just appeared, and the three of them suddenly found that the dashboard inside their mecha was spinning around, and all the values were out of the table.

"What is this?" Wang Ru looked surprised and couldn't help asking.

"Magnetic interference levitating mine, named 'Lost Trace'. Su Yunhan paused and explained simply, "There is darkness and no light underground, and mechanical beasts mostly use geomagnetic fields to judge their directions, and the 'Lost Trace' can disturb their magnetic sensing organs, causing them to deviate from their targets and move towards the Lost Trail. ”

"Trace, and this kind of weapon?" Zeng Zishi looked surprised and said excitedly, "If it can be extended to the army, it will be much easier to deal with underground beasts in the future!"

"Well, let's think about it later. Su Yunhan smiled faintly and said in a deep voice, "Do you see the laser mark on the ground below the 'Lost Trace'? This will be the location where the giant beast comes out, once the giant beast emerges, immediately gather fire and kill it!"

"Yes!"

The crowd echoed in unison.

The three assault battalions each looked for cover, their crossbows held alof, their barrels charged, and they were ready to take aim at the cross mark on the ground.

Rumble!

Not long after, with the tremor of the earth, a huge head emerged, splashing countless rolling stones, and smoke and dust swept the heavens and the earth!

And the place where the skull emerges is exactly where the cross marked, and it is exactly the same.

"It's amazing!"

"This is also ...... That's accurate, isn't it?"

For a moment, the three of them were stunned, and they lost their minds.

"-Fire!"

Su Yunhan gave an order, and the blazing white laser shot directly, like a turbulent rush, and washed fiercely on the skull, splashing white rays everywhere!

Boom! Boom!

The loud roar, the white mangs were waves, but they were like a tide hitting a reef, and they were broken and splashed in an instant.

"What? What kind of defense is this?" Zeng Zishi's face changed drastically, and he almost wondered if the mecha gun in his hand was a fake.

"Yes-Negative Mountain Turtle!" Meng Lei recognized the beast and showed a headache on his face, "Moreover, it's definitely an old guy! Looking at its skin, I'm afraid it's thicker than the mecha tower shield!"

"Keep attacking, don't stop!" Su Yunhan ordered.

"Yes!"

Boom! Boom!

Dao lasers spurted, almost connected in a line, but the giant beast ignored it, and slowly crawled out of the ground under the heavy laser frenzy. It is shaped like a giant tortoise, but its back is high and protruding, like carrying a mountain, and it is a powerful beast known for its defense - the negative mountain turtle.

"Captain, the flow crossbow is not good, you still need some heavy firepower!" Meng Lei said loudly.

"I know, you continue to interfere with it, I need some time to prepare......" Su Yunhan nodded, and shouted in a deep voice, "Arsenal ,—— fortress cannon mode!"

"Fortress cannons?"

Everyone was stunned when they heard this.

Click!

Wu Qu's legs were slightly bent, and the squatting action was like sumo wrestling, and as his feet landed, the surface of his feet actually cracked in a cross shape, nailed deep into the ground, like a heavy fort, as stable as Mount Tai.

Obviously, this is to protect against the recoil of weapons.

This weapon is quite scary!

The three of them looked at this scene and came to the same conclusion.

Click!

Wu Qu's palms were raised high, and his arms were like petals that were split and reorganized, and they were only momentary, and they had turned into two multi-barreled machine guns.

Each multi-barreled machine gun has only four muzzles, and the muzzles are thicker but better than the barrels, which are bottomless at a glance, overflowing with a thick and colorful breath of death, which is terrifying!

For a while, all three had some difficulty breathing.

"Die!" Su Yunhan said in a deep voice.

Before the words fell, the barrel of the gun rotated, and the red mang continued to spew, and in an instant, everyone seemed to hear the mourning banshee's terrible wail, and the howl went straight into the soul, making the soul tremble!

Boom! Boom!

The guns exploded continuously, and what spewed out was not a magnetic storm jet, but a scarlet sphere, which was a collapsed form of plasma, like a small sun, with tyrannical energy and indestructible!

In an instant, the plasma balls shot straight and converged into a red river, like a bend of the forgotten river, those who stood in the way died, invincible!

Roar!

For the first time, the turtle showed fear, and with great effort, it flipped its body with great effort, intending to resist the bombardment of the machine with its huge back.

Bang! Bang!

In just an instant, the landslide collapsed, and the back of the negative mountain turtle was almost flattened!

"I'll go, it's really a heavy weapon......" Meng Lei's tongue was dry, and he didn't know what to say.

This fortress cannon mode is indeed terrifying, and even more powerful than the real fortress cannon, it is by no means much inferior!

A trap mecha can spew out firepower that is not inferior to that of a fortress gun?

It's also terrifying!

Roar!

The Negative Mountain Turtle kept rolling, its four paws fluttering wildly, and wailing.

But at this moment, another majestic beast roar sounded, and it corresponded from afar.

"What's going on? What is it?" Wang Ru was taken aback.

In the depths of the jungle, a blood-colored giant beast with a long tail swept through the giant tree, and slowly walked out with a surging evil aura.

It's a blood crocodile!
