Hiding in the relatively safe rear, observing the battle situation on the second battlefield in the fourth planet's orbit can be maintained stably from the Emerald Star and the Lagrange point region of Satellite No.1.

From the first light beam burst, the entire battlefield was silent, with only deadly sharp beams exchanged back and forth, as each side's protective barriers nullified the other's attacks.

The 500 battle motherships, each a kilometer long, had already released all their tactical jets. Each tactical jet was equipped with an Element Annihilation Bomb, with only one chance to inflict a deadly threat on the biological space motherships. In total, at least a million Element Annihilation Bombs appeared on the second battlefield, just to exchange for a second batch of nearly forty biological space motherships. This might seem extravagant, with an apparent excessive firepower issue, but in terms of the Emerald Star and its star system, adding two more zeros to the number of Element Annihilation Bombs prepared would still be a bargain.

The emergence of the automatic floating field shield indeed increased the survival probability of combat units on the battlefield. After the starlight cannon array and self-floating magnetic railgun fired in the second battlefield, the loss rate was lower than expected.

The Artificial Intelligence AI "Adam" constantly collected data, established relevant models, and simultaneously learned independently.

Learning is the main feature of AI. Without learning capabilities, AI would be no different from ordinary computer programs.

To demonstrate the effectiveness of tactics, the loss rates of both sides were displayed in curves. Each battle resulted in numerous curves, summarized and categorized into multiple chart formats.

The battle mothership group held the biological space mothership group firmly in the second battlefield, providing cover for the long-range strikes of the starlight cannon array. Tactical jets and space biological combat weapons tangled together, covering a radius of 0.5 light seconds, densely packed, like countless small dots performing Brownian motion.

In terms of sheer numbers, biological space motherships released these bizarre and unusually agile combat creatures in the void, completely dominating, outnumbering the tactical jet group by tenfold, even a thousandfold. Even if the number of biological space motherships was fewer than Chen Fei's battle motherships, given that they prioritized a biological technology route and had capabilities similar to "seed nest," it would be a pity if such large biological space motherships did not carry a considerable number of combat subunits.

In addition to the ship's energy beam strikes, the biological space motherships released a large number of space biological combat weapons in a soldier-fodder tactic. Both sides were well-matched opponents. If the current Blue Star sovereignties' active military were to face them, a few rounds would see societal opinion and public pressure enough to replace the current ruling team, as they couldn't afford the losses. It was only Chen Fei, this reckless young man, together with the stubborn Louis Industrial Company, standing at the forefront.

The massive number of tactical jets released by the battle motherships couldn't fly in formation; they could only fight individually, spreading out to lure the extraordinary number of space biological weapons away from their battle mothership. Once the number following reached a certain threshold, they would crash into the midst... and self-destruct!

AI had no concept of life and death. Every pale blue light orb quickly expanded in the dark void, taking with them a large number of enemy space biological combat weapons. The self-destruction threshold was reflected in the charts and curves in front of Chen Fei. Currently, exchanges of forces were orderly, consuming the opponent's forces.

In the chaos of battle, many losses often stemmed from unpredictable stray shots. Tactical jets controlled by AI with multithreading rarely made friendly fire mistakes, but among the side of rampant monsters, it happened like routine. A considerable amount of the losses was due to self-inflicted casualties, yet this chaos disrupted AI's calculations and predictions. Many tactical jets, even before detonating their Element Annihilation Bombs, were affected by space biological combat weapons that exploded prematurely, rendering some Element Annihilation Bombs ineffective. They floated intact with their wrecked bodies in the void.

Half an hour into the battle at the second battlefield, the first biological space mothership was blasted apart by the starlight cannon array focused fire. It was the smallest, about 5.6 kilometers long. The front kilometer of its body was scorched through by a high-density energy beam. However, the most effective armor-piercing tool, the Element Annihilation Bomb, did not get the first hit.

Chen Fei originally thought achieving the first victory would take at least two and a half hours, only to find it was accomplished shortly after the battle began. Biological space motherships in multiples are exceedingly difficult to deal with, becoming tougher with numbers. Once they formed a group of over ten, with simple cover and alternating attacks, it was enough to give Chen Fei headaches. His units were not tough, their attack power was barely adequate for the stage.

Until now, Chen Fei had no choice but to continue with the war of attrition against the biological space motherships, for there were no other tactics — absolutely none. Each confrontation had to be faced head-on, annoyingly so.

If it weren't for this attrition strategy, the Blue Star sovereignties wouldn't support this bold guy, who dared to pummel even the "Lord of the Sky's" son to the brink of death, standing upfront. They provided manpower and resources, albeit now slightly restricted, but previously without reservation enough to avoid delaying the battle over the Emerald Star.

Although the vast reserves stored in the "spatial branding" could support four or five more battles like that of the Emerald Star's star system, engaging in a prolonged war with the "Sagali" civilization would be insufficient, as the opponent owned not just one life planet. Chen Fei, at most, had the Blue Star, barely plus a Cangqiong Star. Despite some support, due to the recent strain between the two civilizations, this too became very limited.

Even with a continuous flow of resources, a huge problem remains. Even with the awakening of Special Abilities, Chen Fei's lifespan was no more than a mere thirty to forty years in warfare, assuming he survived every battle by sheer luck. It's hard to avoid cracking a pot by the well; soldiers inevitably die in battle. The more battles faced, the higher the chance of encountering mishaps, even with God's blessing.

At most fifty years, when he becomes an elderly mortal, where would he find the vitality and spirit to continue fighting against the long-lived parasitic species?

"Sagali" civilization need not do anything. Simply waiting for a hundred years, even if Chen Fei could be the biggest roadblock against their occupation of the Blue Star, this resistance would naturally fade with time.

This, Chen Fei knew, the Blue Star sovereignties knew. How could the "Sagali" civilization not understand?

Therefore, according to the strategic direction most beneficial to the Blue Star, even if the "Sagari" civilization ceases its activities, Chen Fei still needs to provoke actions proactively, aiming to deplete the war resources of the "Sagari" civilization during his lifetime as much as possible.

In tasks like creating disturbances, Chen Xiao'er is undoubtedly skilled. Even Wufeng can stir up waves, targeting the combat forces of the "Sagari" civilization to inflict various outputs, comparing the proficiency of industrial assembly lines versus hatcheries in explosive soldier production.

"'Adam,' tabulate how many biological space combat weapons have been released by the biological space motherships on the second battlefield?"

Chen Fei issued a new statistical command to the Artificial Intelligence AI.

Adam: The current possession of enemy biological combat weapons stands at 2,438,309/7,493,833 units, with an increase of 8,700±200 units per hour.

Subsequently, a pie chart marked the percentage ratio of surviving biological combat weapons to tactical jets on the second battlefield, with an enemy-to-us ratio of about 4:1. The space biological combat weapons of the "Sagari" civilization predominantly have the upper hand, continuously releasing without pause.

After all, the biological space motherships breeding these space monsters are significantly larger in size than the combat motherships carrying tactical jets. The latter's compact load is only 2,000, with most space used for stacking tactical jets. If it weren't for unmanned combat, the actual load might have to be reduced by a zero.

Biological space motherships from farther afield are gradually arriving, with 39 confirmed to be on the way so far. This is due to Emerald Star utilizing the "Wormhole Cloud" technology for remote planetary invasions, not requiring too many of these behemoth biological space motherships.

In a place specialized in explosive production of biological space motherships, with at least tens of thousands of years of continuous accumulation, seeing thousands upon thousands wouldn't be surprising.

If a thousand biological space motherships appeared in the Solar System where Blue Star is located, Chen Fei would unhesitatingly abandon resistance, trying to package all Blue Star Humans into the "Boundary Pearl" Life Space. Originally, without the spiritual power support of a "Life Tree," it would be somewhat troublesome.

But now, with a diameter of a thousand kilometers scraping even the ground, it won't take long to uproot three inches deep, taking the vast majority of Blue Star Humans into the boundless void on a path of exile.

The combination of "Boundary Pearl" Life Space and the presence of a "Life Tree" mutually reinforce each other, qualitatively upgrading the Blue Star civilization's "Ark Plan." A mere airship's journey through the starry sky can't compare to a continent measuring over ten thousand kilometers in diameter, a real Little World. Even if no habitable planet is found, Blue Star Humans can continue to thrive and multiply in the Life Space of the "Boundary Pearl," though it might be a bit cramped, and family planning is inevitably necessary.

"There are about 600,000 tactical jets left, which will be exhausted within 96 hours."

Chen Fei reported the progress of the second battlefield to his people.

Miyoshi Xuesen asked, "Do we need to continue supplementing forces?"

If all tactical jets are depleted, the remaining combat motherships alone would struggle to resist the group of biological space motherships and numerous space biological weapons with their own combat power.

The current loss ratio between combat motherships and biological space motherships is twenty to one, slightly disadvantageous.

If the protection level of the combat mothership's fields could match that of biological space motherships, the situation wouldn't be as challenging as it is now.

"I haven't decided yet."

The reserve of combat motherships in the "Life Space" is still 400 units. Chen Fei is not panicked but is reluctant to play this trump card too early.

Miyoshi Xuesen suddenly had a flash of inspiration, clapping his hands, loudly saying, "You can also use space biological weapons! That big tree is fundamentally a controllable 'Seed Nest,' using their own methods against them; Emerald Star is your supply point."

Before coming to Emerald Star this time, he would never have thought of this idea until Chen Fei used the "Seed Nest" as a growth resource for the "Life Tree," which slightly enlightened him.
