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

It seems that they have also been issued a mission by Nightmare Space to attack the Terran base, but the number of troops of this group of contractors is only half that of Zhao Futu, and it seems that they have been redeemed through special means. Zhao Futu was not interested in saying anything more to them, just said hello from afar, and rushed towards the brood base with his army, his casualties were not small, and he needed to go back to replenish them.

But.

According to Zhao Futu's estimate, his mission with these contractors should have been released around the same time.

However, he completed the task a day and a half ahead of schedule, which was bound to alert the other two Terran bases, and if the group of people in front of him wanted to attack them again, I am afraid that the only way left was to attack.

Three hours later.

Zhao Futu rushed back to the brood base, and at this time the brood base had been upgraded to a third-level brood.

The third-level brood is very large, faintly from the surface area, it is almost equivalent to the size of a football field, and the area of the ground is even larger, Zhao Futu estimated that the diameter is more than five kilometers. After upgrading to the third-level brood, the appearance of the Zerg buildings in the base has also changed, not only has the size become larger, but the consumption of hatched creatures has also decreased a lot.

The most obvious of these is the Velocitor, which actually reduces the energy crystals consumed to hatch an embryo to 25 units.

That's half of the original!

However, there is little change in the classes above the second order, and the hatching price of the third order class is basically above 1,000 unit energy crystals.

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

Because of the exchange option of the brood base, most of the contractors at this stage have gained a lot of benefits through the exchange of energy crystals. Some powerful contractors have even exchanged a lot of silver-level items that can increase attribute points. Maybe it's because the casualties of the contractors are too great, and the Nightmare Space has been consciously improving their strength.

The battle has reached now, and the rough statistics have basically come out.

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

………………

After the main base is upgraded to a level 3 brood, many new Zerg buildings can be built.

For example, upgrade the Wyvern Tower to build the Queen's Lair and the Mammoth's Lair. The price of building this acupoint is very staggering, basically above 10,000 units of energy crystals. If it weren't for the fact that Zhao Fu Butcher had five sub-bases to support him, he would not be able to support such a huge consumption at all. But now he has quite a lot of money in his hands, and after completing the establishment of this cave, there are still nearly 150,000 units of energy crystals used to improve biotechnology and create armies!

But.

Zhao Futu didn't be happy for long, and the cold prompt sound of the nightmare space sounded:

"Contractor number 1013, the brood base will be in full counterattack in three days! …… Gather more than 10,000 troops in three days. The army of the converging brood base launches an all-out assault 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 more than ten million!

Because the brood base controlled by the nightmare space has begun to be upgraded to a fourth-level brood, the limit level of the main base under Zhao Futu is level three, probably because a certain Xuan is shackled, and the brood base controlled by him does not have the ability to upgrade to a fourth-level brood. During this time, he returned to the interior of the brood base once, and has started building the Giant Spore Space Cannon within the confines of the main base!

That kind of giant spore energy anti-aircraft cannon that is more than two hundred meters high. It is possible to launch an attack directly on an interstellar warship outside the planet's atmosphere.

At the same time, there is also a huge and incomparably large sarcoma above the brood base controlled by the Nightmare Space, with a conservative estimate of more than three kilometers in diameter, and the interior is constantly wriggling and contracting, and the Zerg army basically does not have such a large volume of units. After seeing such a stage of sarcoma, the first thought that popped up in Zhao Futu's mind couldn't be that Nightmare Space planned to hatch the Zerg's interstellar mothership, right?

It's all known. The Zerg's flying units are not very powerful, and most of them are only suitable for Star Wars.

But there is no doubt that the Zerg also have the ability to travel interstellarly, and even the brood base controlled by the Queen of Blades is used to open small wormholes for space jumping.

Regarding the opening of wormholes, the prerequisites required are too high to be achieved.

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

The reason why Zhao Futu confirmed this was that he had discovered that the brood base controlled by Nightmare Space had begun to hatch the 'Great Flying Dragon'. That is, a Zerg unit that is more than five times the size of an ordinary Wyvern, has a special mucus film on the outside, and is the only Zerg unit with the ability to fly in space! This is something that even Scorpio and the Air Guard can't do!

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

The progress of the plot has developed to the present, and for some low-strength contractors, there is basically not much to do with them.

This time, the gold-level main story is different from the last one. The real danger was at the beginning, because by that time the Zerg army had basically occupied most of the planet. However, at this stage of the transition of the plot, the main force of the war has changed from the contractors to the army of the Zerg, and what is really wrestling on this planet is the nightmare space and the dimensional pan-consciousness. The contractor can only help from the side.

Even if it is a veteran, it is impossible to compare to a regular Zerg army in terms of combat effectiveness!

And the brood base controlled by Nightmare Space only takes an hour or two to create a standard size of two thousand units of Zerg army.

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

However, the upper contractors, including most of the veterans, began to be issued by Nightmare Space with one main battle mission after another, including territorial expansion, base capture, mineral plunder, and so on.

As one of the few contractors who mastered the brood sub-base, Zhao Futu was immediately issued a main battle mission for a full-scale counteroffensive!

………………

Three days.

It was not very abundant for Zhao Futu, and he had to complete the army replenishment as soon as possible.

At this stage. There has been a lot more hatching at the brood base.

As the Mammoth Lair, Queen's Lair, and Great Wyvern Tower are completed, a new hatching list will appear:

"Incubate the Male Peak - 50 Energy Crystals."

"Hatch the host - 100 energy crystals."

"Hatching the Velociator - 25 Energy Crystals."

"Hatching the Stinging Snake - 125 Energy Crystals."

"Hatching the Wyvern - 300 Energy Crystals."

"Suicide Bat - 100 Energy Crystals."

"Hatch the Lurker - 250 Energy Crystals." [The precursor creature is a stinging snake!] 】

"Hatching the Great Wyvern - 1000 Energy Crystals." [The pre-creature is a wyvern!] 】

"Hatching the Queen - 500 Energy Crystals."

"Hatching the Sky Guardian - 1000 Energy Crystals." [The precondition is a wyvern, an anti-air unit.] 】

"Hatch the Scorpion Guard - 1500 energy crystals." [The precondition is a flying dragon, a ground unit.] 】

"Hatching a mammoth - 3,000 energy crystals."

"Hatching Scorpions - 1800 Energy Crystals."

"Hatching Brain Worms - 15,000 Energy Crystals."

………………

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

Even if the brood base continues to be upgraded, it is only the abilities of these classes that are strengthened, and there is not much change in other aspects.

Zhao Futu now had nearly 180,000 units of power crystallization in his hands. If it is used to hatch velociraptors, then tens of thousands can be hatched in one breath, but if it is used to hatch mammoths, then only 60 can be made. This is the gap between the high-level and low-level troops, and the huge resource consumption makes the deployment of the army must be controlled within the range.

However, after fighting with the Terran army. Zhao Futu had other plans in his heart.

First!

It's that he's ready to give up air combat, which means that he basically doesn't plan to keep the Wyvern troops anymore.

He has fully advanced all of his Wyvern troops into Scorpio Guards, that is, the air-to-ground giant Zerg units he has encountered, which are not very fast, but their ground attack capabilities are very strong.9 One of the most striking features is that it is by far the longest-range Zerg unit, almost equivalent to the range of a sniper!

Zhao Futu hatched more than thirty scorpion guards in one go. Sixty or seventy thousand units of energy crystals were spent.

And then.

He began to hatch the 'Suicide Bat', a small flying unit of the Ruin Clan that was a one-time consumable.

They are small and extremely agile, and fly fast, almost as fast as a Ghost Fighter, though the only downside is that they are very ice-based and capable of killing one by a Terran Heavy in a few strokes. However, these suicide bats have to deal with flying units, and if they are hit by it, it will immediately explode violently. A killer class of airborne units!

Zhao Futu created 300 units of Suicide Bats, replacing the original Wyvern Legion as the air guard.

To be honest, the air units of the Zerg have not been very strong, because the pertinence is too strong, and the advanced units of the Wyvern are either specialized in the air or the ground, although they can be advanced to become the 'Big Wyvern'. But that's not as good as the flying classes of other races. So Zhao Futu simply gave up the air battle and turned the main force into an air-to-ground scorpion guard, anyway, he acted with the Nightmare Space, and the main base had already hatched a lot of big flying dragons.

Subsequently.

He began to create ground combat units. The Stinging Snake only retained a five-hundred-unit establishment, but the Mammoth Behemoth was made ten in one go.

Then there are a number of Lurkers, Scorpions, and Queens, as well as a massive number of basic combat units, Velociraptors!
