Half an hour later, more than 10,000 robots who entered the cave to search returned to the surface with dozens of robot remains.

At this time, the remains of fifty eighth-generation robots were quietly placed on the ground, looking at the scene in front of him, Ling Feng's face was extremely gloomy.

These fifty eighth-generation robots have dozens of small circular holes all over their bodies, as if these robots have been burned and melted by some kind of high-temperature light.

Dark Ray! It's a ray of darkness again!

Seeing the various small holes that appeared on the robot's metal body, Ling Feng was sure that these were all caused by dark rays!

Originally, according to the defense strength of the eighth-generation robots, it was difficult for ordinary dark rays to destroy them in a short time, but the appearance of so many small holes on their bodies fully showed that these eighth-generation robots had suffered at least dozens of dark ray attacks before the accident.

In particular, the heads of these robots are all corroded and ablated to varying degrees, which shows that this is the fatal injury that causes the destruction of these robots.

In the end, what monsters did these fifty eighth-generation robots encounter before the accident? Why are the dark rays emitted by those monsters so terrifying, much more powerful than the rays emitted by the monsters that came out of the pile of corpses just now.

Did they meet the fifty vanished mutants before they had an accident? Or did you encounter the Dark Worm Emperor in the cave?

Thinking of this, Ling Feng's heart sank, and he secretly felt that something was wrong, and at the same time, he was even more determined to guess that inside this cave, it must be the breeding nest of the Worm Emperor, and it was very likely that the Worm Emperor was still hidden inside.

Now because of the narrow entrance to the cave, some of his high-powered weapons and equipment can't enter the cave at all, otherwise, with his tanks, helicopter gunships, and hundreds of seventh-generation mechas, these monsters hiding in the cave, no matter how powerful their rays are, are difficult to resist the attacks of their own weapons.

Obviously, he equipped the robots that searched the cave with all kinds of guns and bazookas, and it seemed that it was difficult to pose a great threat to the monsters hiding in the cave.

Thinking of this, he sighed deeply, and then began to bow his head and ponder.

He had to come up with a good solution to the problem as soon as possible, otherwise, it would only be a waste of time to drag on like this.

However, what made him happy was that although the inside of this cave was huge, the exits were limited, and according to the previous investigations of these robots, it seemed that all the exits were sealed by various boulders or black slime.

Therefore, Ling Feng didn't have to worry about those monsters escaping from the cave, at least, during the day.

But at night, this is not the case, because, based on past experience, these monsters appear to be very active at night, and it seems that it is also the time to go out to forage at night.

If you want to completely destroy the monsters hiding in the cave, you must do it before dark, otherwise, once the night comes, these monsters will be disturbed, and maybe they will escape by night.

What now? Do you still want to use the method you have thought of before? Use a variety of bomb weapons to bomb and expand the entrance to the cave until the hole is carved into the mouth to accommodate an eight-meter-tall mech?

Thinking of this, Ling Feng took a deep breath and ordered the robots on the spot: "All robots obey the order, immediately use all kinds of weapons and ammunition to bombard and expand the entrance of the cave, and make sure that the entrance of the cave can accommodate the main battle mecha to pass through."

"Yes, sir!" When the robots heard the order, they all agreed.

After receiving Ling Feng's order, those robots began to dodge all kinds of weapons and shells, and once again bombarded and dug up the entrance of the cave.

I have to say that the efficiency of these robots is really fast!

It took them less than an hour to successfully dig the entrance of the cave into a huge entrance ten meters high and seven or eight meters wide. Of course, this process must have consumed a lot of weapons and ammunition, especially the bursting armor-piercing bullets of the main battle mecha, which were used a lot.

Because only explosive armor-piercing shells can play a key role at such times, and other bazookas and howitzers can only shatter and loosen the surface of the stone at most, and they play a limited role in the excavation work.

But the bursting armor-piercing bullet is obviously different, a 120-mm bursting armor-piercing bullet can easily penetrate the rock layer more than one meter deep, and then burst violently, so that the huge stones within a radius of several meters are broken and fallen.

Anyway, with the bursting armor-piercing bullet of the main combat mecha, the expansion of the hole is progressing very quickly and smoothly.

After those robots cooperated with the help of the mecha to clear all the stone fragments blocking the entrance of the cave, finally, a huge and wide hole appeared in front of Ling Feng's eyes.

"All the ninth-generation robots, piloting the Razer JZ-70 main battle mech, enter the cave with me to search!"

Ling Feng gave an order, and suddenly, there were three hundred ninth-generation intelligent robots, controlling the mecha, following Ling Feng's mecha, and Yuguan entered the huge pitch-black cave. At the same time, he also ordered 2,000 eighth-generation robots, holding various arms and weapons, as well as search and detection equipment, to enter the cave together and cooperate with the mecha search.

This time into the hole, Ling Feng was ruthless, and even the PF97 93mm individual soldier cloud burst bomb, he had prepared thousands of sets.

Before, he should have equipped the robot that entered the cave to search with a single soldier cloud burst bomb, but at that time, he was too anxious and forgot about this stubble. Because, in the past month or so, he basically used armed helicopters and main battle tanks, and he never used individual cloud burst bombs at all.

Because, he has used individual cloud burst bombs a few times to deal with a group of mutants, although cloud burst bombs can cause damage to them, but those mutants can actually rush out of the center of the explosion and burn, and the cloud burst bombs can't trap the large fierce monsters at all.

Therefore, since then, Ling Feng has never used a single soldier cloud burst bomb.

However, this time the situation is different, and perhaps, the individual cloud burst bomb can unexpectedly exert great power.

You know,This time the combat environment,It's a huge karst cave like an underground labyrinth.,The space inside is relatively closed.,Under this closed space.,The power of the cloudburst bomb will explode and grow exponentially.,If it's used well.,Maybe you can force out all the monsters hiding inside.。

As long as the cloud burst bomb forces those monsters out, Ling Feng's main battle mecha is the real main force to deal with monsters.

Soon, under the leadership of Ling Feng, nearly three hundred seventh-generation mecha entered the interior of the huge cave one after another.

Suddenly, the heavy stampede sound of hundreds of mechs as they walked shook the cavern.

In order to avoid interference from external sounds, Ling Feng temporarily adjusted the strategic helmet in the cockpit to a soundproof and anti-interference mode.

Ten minutes later, all the mecha entered the core area of the cave, and the two thousand eighth-generation robots following behind the mecha team also carried thousands of sets of PF97 93mm individual soldier cloud burst bombs and followed.

Sitting in the cockpit of the mecha, Ling Feng thought for a moment, and then began to command and arrange.

First of all, he divided the three hundred main battle mechs into fifteen combat teams, each mecha detachment, each with more than 100 eighth-generation robots and seventy sets of individual cloud burst bombs, scattered to various dark and hidden corners in the cave, and fired a large number of individual soldier cloud burst bombs in some relatively narrow and hidden places, but the mecha could not enter, regardless of whether there were monsters hiding inside, anyway.

He still doesn't believe it, thousands of sets of individual cloud burst shells, thousands of ammunition, and I'm afraid that he can't force out the dozens of monsters and mutants hiding inside?

As long as those monsters and mutants, once they were forced out by the cloud burst bomb, suddenly, the fifteen main battle mechs of each detachment were all turned on with burst armor-piercing shells, waiting for them.

Even if the dark ray power of those monsters is terrifying, but if you want to damage the mecha in a short period of time, it is simply impossible, you know, the seventh generation mecha is an iron mountain with a height of more than eight meters, and the heavy weight is at least dozens of times that of the eighth generation robot.
