The silicon crystal mine seized this time made Zhu Tianxing, the madman, even more crazy. War can indeed bring huge wealth.

The amount of energy required for the breeding tower to enter the fourth stage was far beyond Zhu Tianxing's expectations. Zhu Tianxing had also asked Tina about this, but she, a genetic expert, did not know about it.

The Arachi biological civilization itself is like a creature, which is very different from other civilizations. As long as the scientific and technological civilization has powerful weapons, it will not be subject to other restrictions. The elemental civilization itself is very powerful, but the Arachi civilization must decide the direction based on the development of the empty master. Once the direction is determined, it is difficult to reverse. Especially Zhu Tianxing, the newly appointed controller, everything needs to start from scratch.

The first stage of the breeding tower is entirely based on the inheritance memory in the mind of the controller. This is equivalent to the juvenation period of a creature. Its own strength is very fragile compared to other advanced civilizations. The second stage is the extension of the Arachi biological civilization. The species gene fusion and transformation make the organisms become stronger, but this can only be regarded as the civilization entering the growth stage. It was not until the third stage that the controller itself began to gain control of the civilization, which marked the gradual maturity of the Arachi biological civilization.

In the first two stages, all Arachi civilizations or all similar biological civilizations are similar. From the third stage, civilizations will be distinguished by the controllers. The same Arachi biological civilization is also moving towards different development paths at this time. In other words, with the current strength of Zhu Tianxing's creatures, even if they encounter the previous controlled creatures, they will not lose even if they encounter the last controlled creatures. Although he has not entered the fourth stage yet, of course, the prerequisite is to use the existing creatures as the standard, not to mention the space species that have not yet appeared.

The fourth stage was the heyday of Arachi Bio. It was officially entered the era of advanced civilization. Although he had no idea about the specific situation of the fourth stage, there was one thing that still had some vague memories in his mind.

The number of organisms determines the amount of energy required in the fourth stage. Zhu Tianxing doesn't know where this information comes from, it seems to be from the memories of past generations. In short, Zhu Tianxing still made the order to stop reproduction of organisms. It's not only because of this vague memory, but mainly because so far, the breeding tower gives nearly half of the energy required for upgrading.

After entering the fourth stage, the Arachi biological civilization will change according to the previous direction of development. Zhu Tianxing is unknown, but according to the situation where Arachi biological creatures have been fully developed through war in the past three years, it is very likely that when entering the fourth stage, it is also possible that this standard will also be centered around.

Zhu Tianxing has always been helpless about the use of energy. It can be seen from the particle light knife obtained on the spacecraft that advanced technological civilization is very powerful in the use of energy. A new energy as big as a sesame particle can completely allow the light knife to last for a few days with high intensity, but compared with Arachi creatures, it can only reach half.

Not to mention, it is a completely energy-based civilization.

The power of the Arachi biological civilization is that its high-intensity reproduction ability and the ability to enter the battle as soon as it comes out. These are things that other civilizations cannot do. In other words, even the most powerful creatures in the biological civilization can be replenished in a short time after death. As long as the energy is sufficient, the Arachi civilization will not be afraid of losses.

But Zhu Tianxing has not felt this yet, especially in the absence of energy.

"Sir. Can we leave now?" Bramic's voice sounded behind Zhu Tianxing, pulling his thoughts back to reality.

"Let's go. The creatures are about to arrive in McCas City." Zhu Tianxing took a deep breath. Since he came to this world, he has not been really happy. The only way to make him feel the beauty is that Kailin has disappeared. This kind of silence and depression even infected the creatures. They have seemed a little violent since Zhu Tianxing came back last time. However, only Zhu Tianxing, who is the controller, can feel this.

McCas City is also a strategic fortress city, just like Braba City. The two cities are not very far apart. In the Empire of Light, the two cities stand each other in the gates leading to the empire's internal affairs. They are like two powerful gate gods.

Especially McCas City, its unique terrain is built between two mountains. It is like a gateway. For humans on the Great Six Land, it is undoubtedly impossible to enter the Empire of Light from here.

But Zhu Tianxing is not this big six above the earth. The creatures are obviously not human. The combined effect of the two is enough to make the whole big six tremble.

With the experience of airdropping, Zhu Tianxing did not issue any other instructions to the radar this time.

The humans in the city have obviously received news of the invasion of the biological army. Ordinary people have begun to evacuate and the city's defense array has also been opened.

But they did not expect that Zhu Tianxing would arrive so quickly. According to common sense, the time required to occupy a city is not short. Even if it is a massacre, it may take a certain amount of time.

It has only been a day since I received the news from Braba City yesterday at noon.

However, soon the creatures told these humans the answers with practical actions.

Flying insects and explosive mosquitoes that appeared in the air completely blocked human sight, and various magic weapons and crossbows shot towards the creatures in a dense manner.

However, these things can no longer have any effect on the creatures. Although the armour of the flying insects is not the most powerful, it is not something that these intermediate civilization weapons can destroy, especially physical attacks. Even the wings of the flying insects cannot destroy the shadow, and the light dimmed instantly.

Hundreds of huge hosts and air guards showed their figures.

For a time, countless creatures of all sizes fell from a height of ten thousand meters.

The same disaster as Bulaba City was repeated again, but this time Zhu Tianxing added several creatures, and tank bugs were also listed here.

Zhu Tianxing did not want to waste time in this place. This airdrop was a complete trick for the Light Empire. The lightning-like degree made them arrive before they could respond urgently. However, once the empire was prepared, it would be difficult to make up for it.

The next city is far away from here. As long as the Empire of Light sends its troops to block the road and sets a trap in the city, it will be more than worth the loss for Zhu Tianxing.

The Empire of Light can be called the most powerful empire in the entire Great Six, and there is also a high-level civilization behind it. It is impossible to have something to do without. Just like the last time the bondage scroll in the Kobra Empire caused Zhu Tianxing to suffer a great loss.

In this period, Zhu Tianxing cannot afford to lose at all. His current purpose is to plunder the silicon crystals of every city. As long as civilization enters the fourth stage, it will not be a problem to deal with the Empire of Light.

The landing of mammoths and tank bugs completely shattered the fantasies of all humans in the city. They finally knew how Braba was captured.

What’s different from last time is that today is not a festival, and with the fact that people are already prepared, humans have not gathered together.

After the creatures fell to the ground, they immediately began to attack, especially the tank insects. The scorching acid instantly turned the entire city into a sea of ​​fire. Often, soldiers on a street disappeared without a trace in such an attack.

The mammoths also began to break freely in the city, and their huge bodies were like a tank. Wherever they went, both buildings and humans, they were stepped onto the ground.

Even the mountains on both sides of the city were trembling, and from time to time, you could see a large number of huge rocks sliding down from the mountain.

Low-level creatures were chasing human soldiers everywhere, and everyone had lost the courage to resist until the distant creature army felt that the entire city of McCas had been almost razed to the ground.

In the church, the leader of McCas City did not hide, but led the knights to confront the creatures outside. Due to the effect of the radar, the magician almost turned into a waste. From the former strong man, he has been for the burden of today.
