It turns out that the so-called fixed energy points deducted every minute before the Iron Curtain Device were only used to provide the most basic shield, for example, providing a thousand points of shield value.

If the attack received exceeds the basic shield value of one thousand points, energy points will be consumed to purchase a shield with the same index until all damage is resisted.

This is also a modified version of the Iron Curtain device.

But normally, this shield value is very thick, and it can resist very powerful attacks under normal circumstances, but this time there were so many attacks from alien beasts that it exceeded the strength of the defense.

The energy column of the apocalyptic creature just now destroyed the original shield value of the Iron Curtain device, which was directly replenished with more than 100 million energy points.

The number of alien beasts gathered in the Sixth War City now reaches more than six billion, half of which are level eight or above. With so many alien beasts activating energy pillars at the same time, so many energy points are consumed. In comparison

It's not a big loss after all.

Now most of the alien beasts can activate an energy column in about six minutes, and Qin Nian has deployed a large number of weapons and devices there, and can destroy a large number of alien beasts in one round.

But the most critical thing now is how to recover these energy crystals.

After the current alien beasts are killed, their bodies will disappear in just six hours, and the energy crystals will remain on the battlefield.

But normally, during this period of time, the bodies of the alien beasts will be blown to pieces by cannonballs, or eaten by others of the same kind.

The alien beast family obviously has no interest in energy crystals. They can digest the corpses of their own kind through their stomachs and extract massive amounts of energy from the corpses for their own upgrading and evolution.

But it's a bit strange that it can't digest energy crystals.

But it was precisely because of this that Qin Nian was able to recover energy points.

Now a huge problem lies in front of Qin Nian, how to recycle energy crystals while fighting to replenish energy points.

There is no time to rest when fighting alien beasts. They don't say that they are like fighting in ancient times. The fight is almost done. Everyone stops to take a rest and tidy up the battlefield before continuing to fight.

They are tireless and will not retreat as long as there is no order to retreat.

This also resulted in Qin Nian's losses on this front.

Now the remaining energy crystals on the battlefield here can be exchanged for 40 billion energy points. Qin Nian needs these energy points to support his battle.

Now his energy points have been reduced to 16 billion. If this continues, the energy points will be exhausted in less than a day.

Without energy points to replenish ammunition, it would be destruction.

"Perhaps Riptide ACV can do the job."

Qin Nian thought for a while and decided to take the risk and give it a try.

Now the alien beasts are engaging in a long-distance bombardment with the War City. There are no alien beasts in the very close battlefield, but the energy crystals here can be recycled.

The more I think about it, the more I think it is possible.

"Host, I actually suggest that you use the Riptide ACV suicide attack again, and then recycle it later. The effect may be better."

At this moment, the system prompted Qin Nian.

"Oh? Why?"

Qin Nian was a little confused.

"Nowadays, the level of alien beasts is very high. They basically have some intelligence and can avoid dangerous things.

If you let the Riptide ACV hit them first and destroy them a few times, they will be wary of this kind of thing. Without the commander's order, they will basically not take the initiative to provoke this kind of thing.

In this way, if you send out Riptide ACV to clean up the battlefield, there will be no interference from strange beasts."

"That makes sense!"

Qin Nian immediately followed the system's instructions and first recruited one million Riptide ACVs. Half of them were loaded with high explosives, and the other half were left empty so that the space could be loaded with energy crystals.

In the Sixth War City, 500,000 Riptide ACVs are dispatched again. The battle method is the same as last time. If the number of alien beasts is small, use the weapons that come with them to kill them.

If the quantity is large, then all the explosives on the carrier will be detonated directly.

Facts have proved that this method is very effective.

Alien beasts are also living things, and all living things have an instinct to avoid danger.

In the past, one million Riptide ACVs destroyed themselves on the battlefield, causing huge casualties to the alien beasts.

Now that there are so many of them, every intelligent beast instinctively avoids these deadly little things.

Compared with these alien beasts, which are often more than ten meters tall, the Riptide ACV is really not very big, but after being fully loaded with level six high-explosive energy bombs, it possesses quite a lot of destructive power.

Often just one can destroy a large area.

Because a long-range bombardment is currently underway, the major commanding beasts are also commanding their tribesmen to retreat, trying not to be killed or injured by these things.

In this way, the 500,000 Riptide ACV only self-destructed more than 100,000 vehicles, and successfully drove back the team of these alien beasts, leaving a large space.

Qin Nian smiled strangely, he really didn't expect it to be so simple.

Then without hesitation, he immediately dispatched the remaining 500,000 Riptide ACVs to clean up the large battlefield, and sent truckloads of energy crystals back to the City of War.

The three hundred thousand from before were standing in front, intimidating the team of strange beasts.

Qin Nian was so happy when he saw the battle report sent back. He really didn't expect that the effect would be so good.

In fact, this was also the result of Qin Nian's chance.

Now is the time when the alien beast team is changing tactics. The command alien beast sees that each energy column can collapse a large amount of gravel, and guesses that the city wall will not last long, so it tries to avoid ground impact battles. Qin Nian is like this

The alien beasts were easily driven away.

During a normal impact time, these strange beasts would at most be the same as before, just disperse their positions.

"Let's go, get ready, I'm going to the Sixth War City."

Qin Nian needs to come into contact with energy crystals so that he can use the energy core of light to convert them into energy points.

Previously, they were transported back to the No. 1 Security Base via armed mining vehicles, and then Qin Nian went there to transform them.

But now the Sixth War City obviously does not have the ability to transport it over such long distances, so it can only go there by itself.

Qin Nian is now at Security Base No. 1. If he wants to go there, it will take two hours by the fastest Apollo fighter plane.
