After dodging four laser attacks in succession, Lu Yuan approached the launcher.

There was a high-purity diamond on the launcher, and when Lu Yuan picked the diamond off the launcher with one shot, the launcher stopped working.

Lu Yun took a breath, and at this time, the four-door black-armored man who had originally rushed out of the gate had already chased after him.

After some fighting, Lu Yuan easily solved the four black-armored people.

At this time, Lu Yuan noticed that there were actually four high-energy laser emitters behind the gate.

He couldn't help but shudder, if when he hit just now, the four launchers were activated at the same time, he would have nowhere to dodge.

"I'm so stupid and bold......" Lu Yuan touched his forehead.

Thankfully, the other three laser emitters were damaged, otherwise I would have been here today.

Lu Yuan dismantled all four laser emitters.

Judging from these four laser emitters, we know the level of science and technology of the foreign invaders.

Modern society also has laser emitters, but the power and speed of shooting are simply not comparable to these laser emitters.

Lu Yuan seems that the scientific and technological level of the two sides is at least a thousand years apart.

"This alien race will not invade the earth for the third time!"

Lu Yuan suddenly realized a problem that he had been subconsciously ignoring before.

Just from the layout of this base and these black armor people and laser emitters, it can be seen that the alien invaders have a completely crushing advantage over the earth in terms of technology.

If the alien invaders really attack for the third time, with the current technology of the human beings on the earth, B will have no power to fight back.

Even if you want to fight a nuclear war with aliens, you may not be able to do it together.

Without the cover of the Elder Witch, the aliens could directly hit any target on Earth from space.

Although the countries of the earth have huge nuclear arsenals, they can't fight people, what's the use, Lu Yuan is really thinking about it now.

With such worries, Lu Yuan continued to advance towards the interior of the base.

Because he was worried about encountering the laser emitter again, Lu Yuan took out a few grenades from the space this time and hung them on his waist.

Lu Yuan, an ordinary black-armored man, is not afraid now, but the power of these high-energy lasers is too great, even Lu Yuan can't withstand a blow.

The grenades he had in his hand were used against laser emitters.

These grenades can't blow up the Blackarmor, but they can deal with the diamonds on the laser emitter.

Without the diamond's laser emitter, it can be considered scrapped.

After Lu Yuan crossed this walkway, he was intercepted by the black armor man again.

But there aren't many of them, only six.

Lu Yuan's current means of dealing with the black armor people have been.

In just 5 minutes, Lu Yuan had already dealt with this batch of black armor people.

Soon Lu Yuan came to the end of this passage.

At this time, a very spectacular scene appeared in front of Lu Yuan.

In front of Lu Yuan was a very huge underground space.

He was now standing on the top of this huge space.

From his point of view, there were five floors underground.

There are a lot of huge machines in each floor.

These machines look very sci-fi.

And all the black-armored people Lu Yuan saw were concentrated in the top layer.

In this level, you can also see a row of petri dishes.

There are also some humanoid figures in the petri dish that are about to grow into them.

"Clone!"

The word first burst out of Lu Yuan's mind.

Lu Yuan found a hidden place and continued to observe the huge factory.

After a day of observation, Lu Yuan found that the first floor of the base could actually fly into two factories.

One is a "cloning culture factory" and the other is a "biotransformation factory".

The first factory can be counted as producing materials, and the second factory is complex to process raw materials into a black-armored warrior.

During these two days of observation, Lu Yuan finally discovered the source of the fog.

The source of the fog is a huge material generator.

When the generator is filled with water, it actively sprays a dense fog outward.

There is nothing destructive about these fogs on their own.

However, it does contain some pheromones inside it, which can be used to direct the actions of the Black Armorers.

As for the second layer of the base, it is also a factory, but judging from the current situation, it does not produce biological warriors such as black armor people, but real robot warriors.

Although Lu Yuan had not yet fought with these robots, judging from the one or two robots he occasionally saw, their combat effectiveness was obviously above that of the Black Armor Man.

Lu Yuan sighed in his heart, these robot warriors are so powerful, if they break out of this base and rely on conventional forces, it will probably be difficult for the countries of the earth to resist.

Fortunately, through Lu Yuan's observation in the past few days, the robot manufacturing factory on the second floor seems to have stopped working.

After Lu Yuan weighed it in his heart, he felt that this base must not be retained, nor can it be discovered by other countries.

If this base is retained, if outsiders do invade the earth again, this base is a huge hidden danger.

If a country finds out and controls it, it will also be a huge disaster.

With the urine nature of the human beings on earth, mastering such a powerful power will inevitably lead the country to embark on the path of external expansion.

At that time, even if there are no outsiders, human beings themselves will have to be beaten into dog brains.

This is not a scene that Lu Yuan wants to see.

After having a preliminary understanding of the first-floor factory, Lu Yuan decisively entered from the weak point of the factory.

It was clear that the black armor people were destroyed under Lu Yuan's attack.

Because he was worried about triggering the factory's security system, Lu Yuan did not attack these appliances when he passed by the petri dishes.

It wasn't until he cleared the factory of the black-armored guards that he started working on the petri dishes.

There was a loud bang.

A huge petri dish was shattered by Lu Yuan.

As the petri dish shattered, a mournful bell rang.

Soon there was a sound of footsteps. The entire underground base came alive.

"Bang... Boom... Bang..."

Taking advantage of the fact that the guards had not yet arrived, Lu Yuan desperately destroyed the petri dish.

When the black-armored soldiers of the brigade returned to the factory from the periphery, the petri dishes in the biochemical factory had been almost destroyed by Lu Yuan.

When Lu Yuan was about to destroy the last petri dish, the fastest team of black-armored people had already launched an attack on him.

Lu Yuan ignored the attack of the black-armored man for the time being, he jumped up suddenly, and after smashing the last petri dish with a "bang" shot, he turned his head to deal with the black-armored man.

However, at this time, the second team of black armor people had also arrived at his side.

The third and fourth teams of black armor are not far from him......
