Half an hour later, the last minotaur collapsed in the sea of worms.

These two dozen or so minotaurs still failed to resist the invasion of the insect tide.

There were more than 3,700 stinging insects in total, but Su Bai looked at the minotaur and returned to his roots.

It's nice that people haven't gone out yet, and creatures can deliver themselves to the door.

After letting the bugs carry the corpses of these minotaurs back, Su Bai returned to the mansion and began to wait for the mother nest to devour.

[Scanned steel reserves.] 】

Su Bai, who was reading a book, heard the voice of the mechanical heart.

Before Su Bai could speak, the Heart of Machines flew over, and the holographic projection of the place with steel reserves.

Seeing the projected buildings, Su Bai remembered that there was an industrial area in the city.

There must be a lot of rare elements and steel reserves in the industrial area.

"Can we build a machine factory after devouring all of these?" Su Bai closed the book and looked at the mechanical heart in mid-air and said.

[Analyzing ......]

[Can be reached to open the construction of the machine factory.] 】

"Go ahead, swallow it yourself." Su Bai waved his hand and motioned for the Heart of Machines to devour it by himself.

【……】

The Heart of the Machine froze in place.

"Do you want me to accompany you?" Su Bai said incredulously.

The Heart of the Machine hesitated, flew three times, and then turned around, and then left alone to find the factory to devour.

……

[Bioenergy 432250 has been obtained.] 】

Su Bai calculated that if it was 50,000, it would take 7,482 to explode, and it would need about 410,000 biological energy.

After calculating the 10,000 biological energy needed to transform the earthly stinging insects, there are still more than 10,000 left, and Su Bai uses them all to cultivate the fungus blanket.

There is no way, although the fungus blanket is a little difficult to keep up with now, it still has to continue to cultivate.

After putting all the biological energy into the explosive army, Su Bai was idle again.

Three hours later.

[7,482 Stingworm Elites have been bred.] 】

[Five fungus blankets have been cultivated.] 】

[Transformed 15,000 Earthly Stingworms: Elite.] 】

[An Earthly Stinger Boss has been bred.] 】

[Completed the capture of this city.] 】

[Completed the size of the swarm to 50,000.] 】

[10,000 points have been earned.] 】

[A copy of the Defensive Class Blueprint has been obtained.] 】

[A copy of the Attribute Pill has been obtained.] 】

[Open a new quest and expand the service.] 】

[Please accept five small and medium-sized cities, and the mission time limit is one month.] 】

[Task rewards, five copies of random class blueprints.] 】

[Two copies of Bioenergetic Pill. 】

[Note: Random class drawings can only be turned on for the classes of the activated race, and the Zerg and Smart Machines are currently activated.] 】

When the size of the swarm reached 50,000, the sound of mission completion also sounded.

In addition to the rewards, new missions have also been opened.

Su Bai first used the attribute pill, and after increasing the full attribute by five points, he continued to look at the new task.

The new mission is still simple and brutal, subduing five small and medium-sized cities.

The location system of the cities is clearly marked on the map, and the five cities are all in the east-west direction, and the farthest is near the sea in the south.

The system actually asked him to subdue these five cities, and in fact, the roads connected to these cities and the towns on the way were all objects that Su Bai needed to subdue.

I have to say that this system abacus is playing well, and the least reward is the most live.

But even if there is no reward, he has to do it......

Abominable system!

However, there are several cities in the north that are relatively close to him, but they are not within the scope of the current mission.

On the contrary, it is the east and west and the city in the south direction, and the east and west are still in the past, and the city in the south is not right.

However, combined with the previous minotaurs, they came from the north.

Su Bai suddenly remembered that when they came, they had large and small wounds on their bodies.

Looking at these cities in the north, it is estimated that a big guy has come out of the north.

Depending on the situation, it has no plans to go south at present, and combined with the mission, maybe the system is also indirectly forcing Su Bai to explode troops quickly.

It makes sense when you think about it.

Then Su Bai clicked on the system and used this drawing first.

"Take the 100-year life of the system in exchange for my golden flash!"

"Open it for me!"

Immediately, a golden light flashed!

Successful transaction!

"Fog grass!"

Su Bai was blinded by this golden light.

"MAD system I love you."

【……】

[Obtain the Giant Defensive Class - Leviathan.] 】

The golden inscription appeared in the very center of the sight, and the glittering golden handwriting showed the rarity of the Leviathan.

Su Bai clicked on the details.

Leviathan: Uses its large, reconfigurable body and hard scale armor to resist a large number of complex and changeable attacks. 】

[Infancy: You can use your body to reorganize into a city wall, and if your brain core is not destroyed, you can resist a strong attack from the eighth order. 】

[Growth period: greatly strengthen the hardness of the body, and increase the recombination speed by 30%]

[Adult: The hardness of the body has reached the highest, the defense of the planet has become invincible, and the reorganization speed has been increased by 90%]

[Complete body: It can fly into space with the technology of the Intelligent Machinery Legion, and the body can be reorganized into an aircraft carrier, please reach the complete body to view the specific value, and it can be modified and upgraded with the intelligent machine technology. 】

Su Bai looked at this introduction and understood what a golden class is, and the value of the juvenile stage can have such a violent effect.

And it grows into a complete body, and can fly into space with intelligent machine technology!

Originally, Su Bai was still thinking about how to use the existing resources to fly into space, but now the opportunity came directly.

As for the bioenergy needed to cultivate the Leviathan.

[Juvenile Leviathan: 100000]

[Note: It takes one million bioenergy to break through to the growth stage.] 】

A Leviathan needs 100,000 bio-energy, good guy, straight good guy.

Originally, I thought that there would be no special shortage of biological energy, but now it seems that there is a shortage of biological energy even more than before.

It takes a million bio-energy to grow, and these figures are a perfect illustration of what a golden class is.

Strong, of course strong, no money.

Su Bai experienced this feeling again today.

Take a deep breath, turn off the panel, and get ready to see how the Heart of Mechanic is going.

When you arrive at the industrial area, you can see that the Heart of Machines is scanning and devouring everywhere.

You can see that all these steels and rare earths are in its pocket.

However, Su Bai felt that these buildings gave him a feeling of missing arms and legs, and how he felt that he had swallowed the steel of these buildings.

After a few more circles, it stopped in front of Su Bai.

[The energy has been replenished to 100%, and the steel reserves have reached 578 tons. 】

[To meet the requirements for the start of the construction of a steel factory, please select an address.] 】

[In order to save steel materials, you can choose to modify the current area.] 】

[The renovation only needs to consume 175 tons of steel. 】

Su Bai didn't even think about it, and he directly agreed to transform the area, and of course he had to save "money".

[Estimated time: 9 hours.] 】

After stating this information, the Heart of Machines turned and flew into the sky, where its inner core sent out light that enveloped the area.

Some buildings are beginning to be perfected at the speed of the naked eye.
