The Trisolaran fleet did not engage in excessive entanglement and began to retreat because the number of human ships was about ten times theirs, and it was clear that humanity had mastered weapon technology of a nearly equivalent level.
What they didn't know was that at this moment, there were no humans aboard the ships that were executing the encirclement.
All the crew and captains were in the simulation pods within seven focal star systems including Blue Maiden Star; the ships were solely operated by real-time communication AI systems.
As long as there were Lightspeed Spaceships, there was no talk of breaking through; even if trapped in an encirclement, entering curvature flight would allow for immediate escape.
The battle saw both sides exchanging blows, with the Trisolarans mainly using two-dimensional weapons because of their large strike area and ability to quickly bring down their opponents.
Soon, Cao Yang noticed that the firepower of the Trisolaran ships was more fierce than that of the human ships, but that was all; they might still have some trump cards they hadn't played, and humanity also had trump cards up its sleeve.
Cao Yang commanded the counterattacks in an unhurried manner. The Trisolarans were not in a rush, so he was even less so.
Cao Yang was clear in his mind that the Trisolarans still thought this was just a simple feint operation, but what they didn't know was that all four of humanity's main corps had been thrown into the battle.
Moreover, the entire human world had already entered a wartime state in advance.
In just one day, hundreds of warships could be produced, and these warships were being sent to the front lines in a steady stream.
The response from Cao Yang left the Trisolaran commanders somewhat disappointed; they had hoped that upon seeing their intent to enter lightspeed, the human commanders would immediately press forward.
This would have given them a chance to try and inflict heavy damage on the human fleet.
Yes, they believed that this was humanity's main force.
It could be said that population and resource constraints had limited the Trisolarans' imagination. Before the destruction of the Trisolaran World, they had never built a vast fleet because of resource scarcity.
To them, a human fleet made up of tens of thousands of warships was almost the stuff of fantasy!
After escaping the Trisolaran World, their population was very small, and they couldn't sustain the construction of too large a fleet.
As a result, the Trisolarans never even considered what it would mean to have a fleet numbering in the hundreds of thousands.
Conversely, they had been expanding their military forces for years and had placed a significant portion of their efforts into the production of warships.
They believed that humanity could not match their efficiency and mobilization capabilities, that although humans were numerous, the number of human warships would only be two to three times that of the Trisolarans.
In the end, the encirclement battle concluded with the Trisolarans' attack fleet entering lightspeed.
Minutes later, humanity's First Corps also entered lightspeed.
Because signals between the ships and simulation pods would be interrupted during lightspeed travel, all ships were piloted by Number Five in the Milky Way during lightspeed.
Cao Yang ordered the soldiers in the command cabin to immediately link up with signals from other warships to support the main battlefield.
At the same time, Cao Yang issued an attack order to Zhuang Yue's Earth Corps.
Humanity's intelligence on the Trisolarans was absolutely beyond Trisolaran expectations.
Back when the Earth Corps clashed with the Trisolarans' First Fleet in Star System Three, several Trisolaran ships "fortunately" broke through and entered lightspeed.
In reality, those few ships were intentionally let go by Zhuang Yue as part of the "Leafminer Plan."
The stealth trackers stuck close to these few ships the entire time.
The Trisolarans were cautious, breaking out of lightspeed several times and only returning to their primary world after seeing that the humans had not followed them.
During the Trisolarans' self-inspection of their ship bodies, those stealth trackers quickly left the ships to avoid detection, but they had already located the Trisolarans' primary world.

Therefore, decades ago, the Trisolarans' current main world had already been exposed.
Some advocated broadcasting the location of this planetary system immediately, but Jiang Yu rejected this proposal.
Because the most economical Dark Forest Strike could no longer harm the Trisolarans in the slightest, it would instead make them wary.
It's possible that humanity's Dark Forest broadcast might even bring trouble upon themselves.
To inflict serious damage on the Trisolarans, one would have to dispatch warships and defeat the Trisolarans on the frontline!
Therefore, the battle plan of luring them into a trap in cooperation with the Starship Earth was merely to disintegrate the Trisolarans' forces and relieve pressure on the frontline.
Before the battle began, Cao Yang had speculated that the Trisolarans' surprise attack fleet was at least one-third of their armed forces.
So now, in the Trisolarans' main world, there were probably only half of their armed forces present.
The Earth Corps, the strongest force of humanity, was in charge of the surprise attack on the enemy's main world.
The Earth Corps was divided into the attack unit and the defense unit, with just the attack unit being more than twice the size of the First Corps.
Zhuang Yue commanded the entire attack unit of the Earth Corps to engage in battle this time, with the specific aim of annihilating the enemy's main force here.
Upon receiving the order from Cao Yang, Zhuang Yue quickly launched the surprise attack.
Just like the tactics of the Trisolarans, there was no declaration of war, no warning; after eliminating the barrier, the attack commenced immediately.
However, the Trisolarans reacted swiftly, intercepting the Dark Matter Detonator-induced dark matter explosions initiated by the Earth Corps.
Indeed, in the present state of technological development between humanity and the Trisolarans, the process of detonating dark matter could be intercepted.
To intercept, one simply needed to dilute the force field emitted by the attacking party, and although it often resulted in a highly probable gravitic chaos zone, careful attention during combat could prevent accidental entry into such chaos zones.
But the Earth Corps's subsequent attacks were something that the Trisolarans found difficult to withstand.
There were large-caliber Dark Matter Cannons, light particles, and two-dimensional attacks.
This was the enemy's homeland, where the Earth Corps could trample at will!
The Trisolarans' warships, being unable to defend successfully, had no choice but to steel themselves for counterattacks.
At this moment the Trisolarans' main force couldn't simply flee; they needed to cover the civilian ships' retreat, and only when they could no longer provide cover would they seek ways to escape.
As the two sides engaged in ferocious attacks, they drew increasingly closer, with casualties on both sides mounting rapidly. Zhuang Yue's tactics were different from the cautious approach previously taken in encircling the enemy's surprise fleet; the Earth Corps's attacks were brutally forceful.
Soon the outer space of the Trisolaran main world was badly damaged, littered with two-dimensional fragments and shattered spaces.
The Trisolarans' main force was stubbornly resistant, and even after their main world was essentially destroyed, they still would not give an inch.
Thus, the battle continued into the surrounding space, and then extended to nearby planetary systems.
It was not until nearly all of the Trisolaran civilian ships had entered lightspeed that the Trisolaran main force began to retreat.
Seeing the moment was ripe, Zhuang Yue immediately ordered, "Use 'The Great Magnet'!"
The so-called Great Magnet, formally known as a large-scale directed gravitation device, could create directed gravity within a short time to flatten the curvature of space within a certain area.
This weapon was developed based on the tactics of Paradise, but humanity still couldn't "iron out" the curvature entirely, only make it relatively flat. What would usually take an hour or two to enter curvature flight now required four to five hours to enter curvature.
It was one of humanity's trump cards.
