Less than two minutes later, the medium and small triangular spike battleships showed amazing maneuverability, quickly dispersing and constantly approaching the human fleet.
The two sides immediately exchanged fire, with various energy weapons and missile weapons of various shapes and flying speeds firing at each other from a distance.
During the exchange, Lei's triangular battleships continued to shrink the encirclement and compress the space.
However, under Lei's fine control that gradually recovered, the triangular spike battleships had additional enhanced power. Even if the distance between the two sides continued to close, the human fleet with a numerical advantage still found it difficult to hit the other side, and was instead subjected to a series of small-scale concentrated fire from the triangular battleships.
In the process of being hit by concentrated fire, even though the human warships quickly put up their own three-force composite shields, they continued to suffer battle damage.
The human fleet quickly fell behind.
Lei Dingdu only used 10% of her computing power to quickly gain the upper hand on the front battlefield.
Her true strength can be seen.
This is the best opportunity that the Free Front has waited for so far.
If it were in the past, let alone seeing her new fleet, she would not even be able to defeat the obsolete armed forces that intercepted her midway.
Almost at the same time, the Eagle Strike Warriors quickly engaged in fire with the War Beast Legion and other small combat unit wargroups.
There are 71 million Eagle Strike Warriors, nearly 100 million War Beast Legions, nearly 100 million small triangular fighters, and the rest are similar to the former sparrows and kites, but the total number of Vipers and Lobsters, which are improved for space stations, is as high as 200 million.
Almost every Eagle Strike Warrior has to face the combined firepower of the enemy that is four times their own.
But no one retreats.
Nearly one-third of the ordinary warriors have been injected with the meteor drug that overdrafts their lives on the way to the front line.
No matter how this battle ends, these 23 million warriors only have two hours left to live.
Their ideological realm has surpassed the level of fearlessness and only unparalleled transcendence and enlightenment remain.
"I, a mediocre warrior, finally have the ability that I once envied and could never reach. Compared to those natural warriors, no matter how hard I practice, I can only be a mediocre warrior. But... today! On this battlefield, I will use my life to shine with the same brilliance as the elites!"
This is a similar thought in the minds of most ordinary Eagle Strike Warriors who have completed the temporary installation of four quasi-curvature engines.
The sudden outbreak of 23 million ordinary warriors with mediocre strength has caused a huge change in the war situation.
A total of more than 70 million Eagle Strike Warriors actually completely resisted the enemy that was four times their own.
Although the enhanced black light war beasts that Chen Feng encountered on Earth last time still cause trouble to a large number of warriors, more than ten people can often defeat at least one or two of them, and they are no longer helpless as in the past.
Three minutes later, the intensity of the battle between the two sides increased further.
Lei's war fortress and mothership have been mobilized.
But at the same time, nearly 3,000 giant motherships of mankind finally released all the mad bee fighters to fight!
The sky above the earth was illuminated as if it were daytime, and Tang Tianxin, who was in control of the overall situation, once again entered that state of high-speed thinking.
At this time, she had the assistance of three other top commanders.
She only gave precise orders to the Martian coalition.
As for the coalition forces of the other three bases, she only needed to give a relatively broad outline order, telling them how to complete the overall maneuver and how to merge.
As the front battlefield progressed, Chen Feng, who was lurking in the ranks of ordinary Eagle Strike Warriors, and the other 100,000 strongest warriors gradually dispersed and approached the four major war fortresses.
Sudden attack! Strong attack!
The human ambush tactics worked.
But at the same time, the situation in the battleship exchange area also changed suddenly.
Lei's large triangular battleship launched a round of seemingly ordinary heavy nuclear proton fission missiles in succession.
Humans used conventional methods to intercept, or relied on the three-force composite shield to withstand it, but they did not expect that after these missiles exploded near human warships, the space suddenly became unstable and violently vibrated, which produced an effect almost like tearing the space.
The strength of the three-force shield was like tofu in front of the tearing of space. More than hundreds of thousands of large, medium and small warships were torn into countless pieces in an instant!
The technicians immediately analyzed the results.
This is Lei's new weapon!
Force field tearing missiles.
Lei used her advanced understanding of the unified force to develop a bomb that can instantly disrupt the force field effect of a certain area, which can instantly tear apart warships and other combat units, and the shield is almost ineffective!
Under the sudden change of the situation, the human fleet fell behind again.
But still no one retreated, Tang Tianxin pushed her flagship forward a little further.
It turned out that, unknowingly, she finally completed her overall layout.
She made a gesture of desperate attack at all costs, with only one fundamental purpose.
On the premise of preserving large battleships equipped with K5 main guns as much as possible, she quietly gathered large battleships in the same hemisphere and continued to concentrate them in preparation for the next piercing attack on the earth.
Now there are nearly 600,000 large battleships remaining, which have quietly completed the initial convergence. She only needs to give an order to instantly switch the formation and turn it into a staggered concentrated fire assault formation.
The concentrated fire assault formation is completely opposite to the arrow charge formation.
The largest number of warships are staggered in the front row of the formation, and then gradually decrease layer by layer until an inverted pyramid is formed.
The purpose of this arrangement is to facilitate the staggered positions of all warship main guns when firing to avoid accidental injuries, and at the same time to make the ballistic angles of all K5 ray guns as small as possible, so as to facilitate the next step of aggregating the ray trajectories.
But now the warships cannot complete the last step of formation integration. Before that, someone must first break into the earth's atmosphere and destroy the giant laser cannons deployed on the ground in advance.
Otherwise, once this formation was deployed, the ten ground laser cannons in the Eastern Hemisphere would open fire at the same time, and if they continued to sweep down, humanity would have no chance of survival.
But this opportunity soon arrived.
Chen Feng and his men at the forefront of the chaos suddenly rose up, sacrificing more than 30,000 comrades, and in just three minutes they completely destroyed the four major war fortresses and hundreds of fortress motherships.
Immediately, Chen Feng and his men did not stop, but broke up into pieces and dispersed, killing into the atmosphere and rushing straight to the ground.
The hundreds of millions of small and micro combat units that Lei had deployed in the atmosphere in advance were already in full formation.
Chen Feng took a deep breath and issued his first battlefield order, "Kill! Break through the blockade at all costs! Destroy all laser cannons!"
After saying that, he switched to the form of an eagle-wing fighter, fearlessly and at full power, crashed head-on into the enemy's formation.
He didn't even need to deliberately fire, the space vibrations created by the eight curvature engines fully turned on could easily tear apart the enemy's war machines in the forward direction.
He was like a sharp knife, turning into a real meteor and rushing down in the atmosphere.
Wherever he passed, there were chain explosions.
Lei's individual weapons couldn't even stop him for a second.
As for the concentrated fire from the massive individual weapons under Lei's control, he still easily avoided it with his quick change of direction, and accidentally injured his own people.
Chen Feng was also intercepted by force field tearing missiles launched from the ground during the charge, but he had already received the intelligence that his teammates in the back had exchanged their lives for, and he sped up again, easily avoiding the space tearing range of the missiles.
He also encountered the interception of thousands of enhanced black light war beasts.
The firepower network interwoven by the injection phase cutting guns was almost impenetrable, but Chen Feng, who had seen this move once, was prepared. He briefly switched to the ultimate form in advance, and the black light battle blade cut through the interception network, and then rushed out again.
Just one minute later, he arrived near a giant laser cannon. Under the live ammunition attack of the ground-to-air mortar and the energy attack of various cluster guns, he changed into a large charge form and crashed into it.
The giant laser cannon that was about to be fully charged was smashed on the spot by him.
The morale of nearly 70,000 elite warriors in the rear was suddenly boosted, and they rushed to different directions to block the cannons that posed a great threat to the fleet.
Chen Feng was indeed not an excellent commander. He could not command as perfectly as Tang Tianxin, but he was undoubtedly the most suitable vanguard general to lead the death squad to charge and capture the enemy.
Tang Tianxin led the army in battle with the art of command, while Chen Feng led by example in a very simple and crude way.
Although he looked very impressive, it was not easy for him.
He found that no matter how he used the dual engines to fully accelerate, there were still more than fifty fighter planes with black rays and thin particle media following him, and he could not get rid of them.
The maneuverability of these specially made fighter planes was stronger than all the war machines Chen Feng had seen before, and their performance was extremely excellent.
Moreover, almost all fighter planes were equipped with reverse magnetic field shields that Chen Feng had difficulty dealing with, making them difficult to shoot down.
This should be the special operations unit that Lei had temporarily modified after discovering his super mobility a few days ago, in order to completely pin him down in the atmosphere.
If Chen Feng's Ultimate Eagle Strike Armor had not been equipped with three more engines, he might have been entangled.
He rushed to the second cannon nearby, which had extremely strong defenses and his comrades had been unable to capture for a long time.
With the arrival of his fresh force, only ten seconds later, his comrades quickly tore through the defense line and poured down the coverage of a large number of martyrdom bombs.
"Hurry up!"
Chen Feng glanced at the tactical helmet and found that more and more enhanced black light war beasts with equally astonishing speed were converging in his direction, so he quickly gave orders.
In the process of escaping the encirclement, he paid attention to the space battlefield again, feeling a little sad, but fortunate.
Since the outbreak of the general offensive, humans have lost nearly 100 million combat forces at a very fast rate, but Lei has only lost half of that at most.
This is the result obtained when her computing power investment is insufficient.
If Lei goes all out, the enemy's battle loss ratio will be at least three times.
However...
the time is finally ripe.
The ten laser cannons on the ground were finally destroyed!
He quietly sent a message to Linbu, the special operations squadron, and the other 3,000 most elite Eagle strike fighters.
"Prepare for action!"
As he sent the message, nearly 500,000 large human warships that had already approached the edge of the near-orbit quickly changed their formation.
Thirty seconds later, the concentrated fire impact formation was formed!
As early as the formation was changed, these large warships had already preheated and charged the K5 main guns in advance.
The charging ratio was 200% overload operation!
Only this one shot was needed!
Five kilometers in front of the impact formation, a spherical aircraft with additional shield energy suddenly rushed in.
This spherical aircraft has been hiding in a human mothership. It is the energy-gathering sphere that Titan Academy's genius weapon development expert Ou Qinglan has just developed and successfully manufactured in two days.
Its function is to gather all K5 rays onto this sphere, and then through a short period of super-strong energy transfer, the trajectories of the rays fired by all the main guns are gathered into one, and shot straight to the earth.
The direction of the shot has been verified countless times, and the key intelligence obtained from a chip raid and an antique box raid in which Chen Feng personally participated directly pointed to the location of Lei's core, which is indeed the center of the earth!
On nearly 500,000 large warships, a total of nearly 2 million main guns simultaneously emitted a dazzling blue light.
The outer layer of the energy-gathering sphere began to appear spiral energy vortexes.
Tang Tianxin suddenly waved his hand downwards, "Fire!"
Nearly 500,000 K5 beams of light burst out and hit the energy ball almost at the same time.
A white light suddenly lit up in the sky, completely stealing the brilliance of the sun that had just risen below the horizon of the Eastern Hemisphere.
However, Chen Feng increased his flying speed even further.
About dozens of kilometers in front of him, a beam of light with a diameter of only five meters, but which had gathered an incomparably huge amount of energy, was falling from the sky and heavily hitting the ground.
When Chen Feng arrived at the impact site, the beam of light had already dissipated.
He lowered his head and looked down, only to see extremely dense white smoke coming out of a circular hole with a diameter of five meters.
This is the hole, leading directly to the ground!
He leaped forward, and in the absence of any visibility, he went deep into the ground at full power.
Less than ten seconds after Chen Feng entered, Lin Bu arrived at the cave entrance.
Before his comrades arrived, the second to approach were fifty power-enhanced fighters of Lei.
Not far behind the enhanced fighters, the remaining three thousand three hundred comrades were flying at high speed.
Behind the three thousand three hundred comrades were thousands of enhanced black light war beasts.
Behind the black light war beasts were more than sixty thousand elite warriors approaching rapidly.
Behind the elite warriors were more black light war beasts and ordinary triangular fighters.
At this moment, the combat power of humans and Lei formed an interlocking layout of three layers inside and three layers outside in this huge semicircular space with a diameter of thousands of kilometers.
The goal of all combat units was exactly the same, that deep hole leading directly to the ground.
This place will definitely become a meat grinder.
Lin Bu switched to a charging form, striding to the entrance of the cave, his eyes focused, murderous intent soaring to the sky, "Come on!"
Then Lin Bu closed his legs and continued to fall down.
He planned to use his body to help Chen Feng block the entrance of the cave, and at the same time prevent Lei's combat units from approaching Chen Feng from underground.
Next, in the few short minutes when Chen Feng went to the center of the earth to find Lei's core, Lin Bu and others had only one task, to hold their position and never let any war machine rush in to disturb him. In the distance,
there was a jubilation in the human fleet camp.
Chen Feng was about to reach the underground!
The sky belonging to humans was about to turn blue.
Underground, Chen Feng continued to advance in zero visibility, relying on the energy shield to knock away the regrouped magma and keep moving forward.
