On the way back, Zhao Futu unexpectedly encountered another wave of contractors.

They seemed to have also been issued a mission to attack the human base by the nightmare space, but the number of troops of this group of contractors was only half of Zhao Futu's. It seemed that they were exchanged for it through special means. Zhao Futu was not interested in telling them more.

What? He just said hello from a distance and rushed towards the Brood Base with his troops. His men suffered a lot of casualties and needed to go back to make up for it.

but.

According to Zhao Futu's estimation, his mission and that of these contractors should have been released at about the same time.

However, he completed the task a day and a half ahead of schedule, which will definitely alert the other two human bases. If the group in front of them wants to attack them, they may have the only way to attack them by force.

Three hours later.

Zhao Futu rushed back to the Brood Base. At this time, the Brood Base had been upgraded to a third-level Brood Base.

The level three brood nest appears to be very large. Judging from the surface area, it is almost the same size as a football field. As for the underground area, it is even larger. Zhao Futu estimates that the diameter exceeds five kilometers. After upgrading to

After the third-level mother nest, the appearance of the Zerg buildings in the base has also changed. Not only has the size become larger, but the consumption of hatching creatures has also been reduced a lot.

The most obvious one is the Velociraptor. The energy crystal consumed to hatch an embryo has actually been reduced to 25 units.

That’s half of the original value!

However, there are almost no changes to the second-level and above-level arms, and the incubation price of third-level arms is basically still above 1,000 units of energy crystals.

In a way, this gold-level main quest is really a great harvest!

Because of the exchange options in the Brood Base, most contractors at this stage have gained a lot of benefits through energy crystal exchange. Some powerful contractors have even exchanged a lot of silver-level items that can increase attribute points.

Perhaps because the contractors suffered too many casualties, Nightmare Space has consciously improved their strength.

At this point in the battle, the rough statistics have basically come out.

Only half of the surviving contractors in the nightmare space are left, which means that the casualties of the contractors have exceeded 50!

………………

After the main base is upgraded to a third-level brood, many new Zerg buildings can be built.

For example, upgrade the Flying Dragon Tower and build the Queen's Lair and the Mammoth Lair. The cost of building these caves is astonishing, basically more than 10,000 units of energy crystals. If Zhao Futu didn't have five sub-bases to support him, he wouldn't be able to support it at all.

He can't afford such a huge consumption. But now he has quite a lot of money. After completing the establishment of this side point, there are still nearly 150,000 units of energy crystals to use to improve biotechnology and build an army!

but.

Zhao Futu was not happy for long, and the cold prompt tone of the nightmare space sounded:

"Contractor number 1013, the Brood Base will launch a full-scale counterattack in three days!... Please gather more than 10,000 troops within three days. Combine the troops from the Brood Base to launch a full-scale attack on the Zerg territory!..."

The main base controlled by Nightmare Space is expanding faster and faster.

Zhao Futu didn't know how many energy crystals it had plundered, but the number was at least over 10 million!

Because the brood base controlled by the nightmare space has begun to be upgraded to the fourth-level brood base, the ultimate level of Zhao Futu's main base is level three. It may be because Xuan Xuan is shackles, and the brood base he controls does not have the ability to upgrade to the fourth-level brood base.

The ability of the fourth-level Brood. During this period, he returned to the Brood Base and started building a giant spore space cannon within the scope of the main base!

That kind of giant spore energy anti-aircraft gun with a height of more than 200 meters. It can directly attack interstellar battleships outside the planet's atmosphere.

At the same time, there is a huge sarcoid in the sky above the brood base controlled by Nightmare Space. The diameter is conservatively estimated to be more than three kilometers. The interior is constantly squirming and shrinking. The Zerg army basically does not have such a large unit. After seeing this

After the stage of sarcoma, the first thought that popped into Zhao Futu's mind was that the Nightmare Space planned to incubate the Zerg interstellar carrier, right?

As we all know, the flying units of the Zerg are not very powerful, and most of them are only suitable for planetary wars.

But there is no doubt that the Zerg also have the ability to travel between stars, and even the Brood Base controlled by the Queen of Blades can be used to open small wormholes for space jumps.

Regarding opening a wormhole, the prerequisites required are too high and basically impossible to achieve.

But hatching Zerg interstellar combat units should be something that the fourth-level brood can do!

The reason why Zhao Futu confirmed this was that he discovered that the brood base controlled by the nightmare space had begun to hatch the 'Big Flying Dragon'. That is, a kind of body that is more than five times the size of an ordinary flying dragon, with a special mucus film on the outside.

, and is the only Zerg unit with the ability to fly in space! Even Scorpion and Air Guard cannot do this!

"It seems that Nightmare Space is planning to launch a full-scale counterattack and take over this planet directly!" Zhao Futu murmured.

The plot has progressed to this point, and for some contractors with lower strength, they basically don’t have much to do anymore.

The gold-level main plot this time is different from the last time. The real danger is at the beginning, because at that time the Zerg army has basically occupied most of the planet. But when the plot transitions to the current stage, the war

The main force has changed from the contractors to the Zerg army. What is really fighting on this planet is the nightmare space and the plane of pan-consciousness. The contractors can only help from the side.

Even a veteran cannot match a regular Zerg army in terms of combat effectiveness!

It only takes an hour or two for the Brood Base controlled by the Nightmare Space to create a Zerg army of a standard size of two thousand units.

The tasks of the lower-level contractors have now been transformed into auxiliary harassment, collection, and defense tasks.

However, the upper-level contractors, including most of the veterans, began to be issued a series of main battle missions by the nightmare space, including territorial expansion, base capture, mineral plunder, etc.

As one of the few contractors who controls the Brood Base, Zhao Futu was immediately issued a main battle mission of a full-scale counterattack!

………………

Three days.

It is not very abundant for Zhao Futu, and he must complete the army replenishment as soon as possible.

At this stage, there are already a lot more hatchings in the brood base.

With the completion of the Mammoth Lair, Queen's Lair, and Great Flying Dragon Tower, a new hatching list has also appeared:

"Hatching the Peak - 50 points of energy crystal."

"Hatching host - 100 points of energy crystals."

"Hatch the Swift Beast - 25 points of energy crystal."

"Hatch Hydralisk - 125 points of energy crystal."

"Hatch the flying dragon - 300 points of energy crystals."

"Suicide Bat - 100 points of energy crystal."

"Hatch Lurkers - 250 points of energy crystals." [The prerequisite creature is Hydralisk!]

"Hatch the big flying dragon - 1000 points of energy crystal." [The prerequisite creature is the flying dragon!]

"Hatching Queen - 500 points of energy crystal."

"Hatch aerial guards - 1000 points of energy crystals." [The prerequisites are flying dragons and anti-air units.]

"Hatch Scorpion Guard - 1500 points of energy crystals." [The prerequisite is flying dragon, an anti-ground unit.]

"Hatch the mammoth beast - 3000 points of energy crystals."

"Hatching scorpions - 1800 points of energy crystals."

"Hatch brainworms - 15,000 points of energy crystals."

………………

The third-level brood almost encompasses most of the characteristics of the Zerg troops.

Even if the Brood Base continues to be upgraded, the capabilities of these units will only be strengthened, and there will not be much change in other aspects.

Zhao Futu now has nearly 180,000 units of ability crystals in hand. If it is used to hatch swift beasts, tens of thousands of them can be hatched in one breath, but if it is used to hatch mammoth beasts, it can only be made

60. This is the gap between high-level arms and low-level arms. The huge resource consumption makes the army configuration must be controlled within the range.

However, after the battle with the human army, Zhao Futu had other plans in mind.

First!

It means that he is ready to give up aerial combat, which means that he basically does not intend to retain the flying dragon troops anymore.

He fully upgraded all the flying dragon units into Scorpion Guards, which are giant air-to-ground Zerg units that he has encountered. They do not move very fast, but their ground attack capabilities are very powerful. 9 There is a very eye-catching one.

The characteristic is that it is the Zerg unit with the longest range so far, almost equivalent to the range of a sniper!

Zhao Futu hatched more than 30 Scorpion Guards in one go, spending 60,000 to 70,000 units of energy crystals.

Then.

He then began hatching 'suicide bats', which were small flying units of the Ruins and were disposable consumables.

They are small and extremely sensitive, and fly very fast, almost as fast as a Phantom fighter. However, the only drawback is that they are very cold. A human machine gunner can kill one in a few hits. But these suicides

The bat has to deal with flying units in the air. As long as it is hit by it, there will be a violent explosion immediately. It belongs to the killer level of flying units in the air!

Zhao Futu created 300 units of suicide bats to replace the original flying dragon army as aerial guard force.

To be honest, the Zerg's aerial units have never been very strong because they are too targeted. The advanced units of the flying dragon are either specialized in attacking the air or the ground. Although they can be upgraded to become a 'big flying dragon', it is not as good as the flying dragon.

Flying units of other races. So Zhao Futu simply gave up aerial combat and turned his main force into air-to-ground Scorpion guards. Anyway, he was operating with the nightmare space, and the main base had already hatched many large flying dragons.

Later.

He began to create ground combat units. Hydralisks only retained a strength of 500 units, but ten mammoth beasts were created in one go.

Then there are a number of lurkers, scorpions and queens, as well as a large number of basic combat units, velociraptors!
Chapter completed!
