Bombs are not the most powerful to explode on the ground; According to calculations, after landing, seventy percent of the bomb's power is wasted; Generally, small artillery shells, which explode about two meters from the ground, are the most powerful; Large bombs are about 10 meters above the ground, and the explosion is the most powerful...... The nuclear bomb, when it is more than ten kilometers away from the ground, or even dozens of kilometers, has the greatest power of explosion; The exact height depends on the yield of the bomb. Pen, fun, and www.biquge.info

But the explosion did not end, as soon as the explosion on the ground ended, more than a dozen unmanned spaceships in space suddenly rushed to the vicinity of the Bosela civilization fleet and exploded!

The power of nuclear bombs in space is much lower - because space is too vast and everyone is relatively far away, but nuclear bombs are still nuclear bombs, and close-range attacks are still "invincible in range". More than half of the ships of the Bosera civilization were scrapped in an instant, and almost all of the remaining ships were injured!

"This is the moment! Rush! Yang Qinghui took the lead, and the Earth Civilization Special Combat Team immediately attacked, and in addition to the spaceships left behind, ninety percent of the spaceships rushed to the planet.

The most tragic battle has begun!

Qin Fei led his team and took the lead; On the spaceship, laser cannons, rail cannons, particle cannons, and even machine guns that are rarely used in normal times have begun to wield power. The cannon on the ship, designed for close combat, can reach a rate of 100,000 bullets in a minute, which is simply a metal storm.

The ships of the remnants of the Bosela civilization rose up to revolt, but it was too late; The desperate alien soldiers let out a final roar, and the ships launched a suicide attack. And Qin Fei, who was in the lead, was hit by this suicidal attack!

When Qin Fei frantically strafed millions of bullets, he was also hit; A spaceship of the Bosela civilization was destroyed, but at the last moment, it still gave Qin Fei a shot. Rail cannon, a very sturdy one. The front half of Qin Fei's spaceship was directly shattered; The ship's intelligence core, particle cannons, and so on, were all shattered.

"Captain?!" Qin Fei's team exclaimed.

"It's fine!" Qin Fei responded, but still drove the broken spaceship forward to sprint. Although the spaceship was broken and the intelligence core was broken, the intelligence core on the mecha took over the control of the spaceship; The remaining two-thirds of the ships are still capable of fighting. This, after all, is a military spaceship!

The cannons on the side of the ship continue to wield power, one cannon can tilt 100,000 bullets in a minute, and three still working cannons tilt 300,000 bullets in a minute! Seeing that the spaceship was finished, Qin Fei no longer cared about consumption.

The bullets bottomed out at a speed visible to the naked eye, and the tens of millions of bullets stored on the spacecraft disappeared in a moment; Then, Qin Fei turned on the destruction device of the nuclear island, the spaceship, and turned it into a flying nuclear bomb!

Bang...... The ejection device took effect, and Qin Fei's black glider mecha suddenly flew out of the spaceship. Compared to the bulky spaceship, the nimble mecha allowed Qin Fei to easily dodge all kinds of attacks. Even if it's a rail cannon, this powerful almost S-class mecha can dodge the past!

The mecha in melee combat is as agile as a ghost, a lightning ghost.

Around, the Earth Civilization Special Combat Team continued to have spaceships destroyed, and mechs began to appear; And the Bosela civilization is even more tragic, and many mechs are destroyed before they have time to escape from the spaceship.

"Kill!" The mecha quickly approached the other party, and Qin Fei was still rushing to the front. Mecha battles are completely different from spaceship battles! The spacecraft is a long-range shot, although the spacecraft is fast, but because it is in the large-scale background of the universe, the relative speed is actually very slow, and the spacecraft trail is not completely impossible to capture.

However, the mecha is different, the two sides are very close, and sometimes they are directly face-to-face; At this time, not to mention the speed of tens of kilometers per second, it is the speed of tens of meters per second, and ordinary people can't react. And now the combat speed and attack change speed of the mecha are tens of thousands of meters per second.

Countless huge amounts of information poured into the brain in an instant, and without a strong mental power to process this information, the brain would inevitably strike.

"Huh......" Qin Fei skillfully pulled out the long sword behind the mecha, and the mecha slashed through space like black lightning, flying hundreds of kilometers in an instant, and the long sword slashed over the mecha warriors of the seven Bosela civilizations! These mechwarriors don't know how they died until they die.

The mecha warriors of the special combat team are all elites, a large number of spaceships are suppressed, and there are mecha leaks, and in just a moment, the Bocera civilization fleet in space will be wiped out; It's just that in such a tragic battle, the earth civilization also paid a considerable price, in less than an hour of battle, more than 40 spaceships were destroyed, and hundreds of spaceships were injured; More than a dozen elites were killed in battle.

"Don't stop, the mecha warrior directly enters the atmosphere and enters the ground to search, and you must not let go of a live mouth!"

Qin Fei heard the order, and immediately turned around and flew down. The impact of the nuclear bomb explosion did not stop after an hour, the wind raged in the entire planetary library, and the ocean formed by liquid methane rolled up monstrous waves, and the pink clouds in the sky continued to shatter, and some clouds even rushed out of the planet.

It's too far away from the stars, and the faint infrared light has tinted the world pink. But pink doesn't mean cute, it represents extreme cold.

"The atmospheric temperature is minus 176 degrees, the atmospheric pressure is 1.23 Earth pressure, and the planet's gravitational pull is 0.21 Earth gravity." The mecha uploads an automatic detection report.

This is a magical planet, after landing on the ground, Qin Fei was attracted, the wet ground, the sky and storms, lightning and thunder, there are sandy beaches and pebbles by the river, but this is a desolate planet here. All of this liquid is almost all icy liquid methane.

It's a dead planet that seems to be full of life!

The power of the nuclear explosion has not disappeared, and the wind is still raging, and the huge wind makes even the mechs unstable.

In space, the special operations team's spacecraft has completed the blockade, and the powerful scanning machine is constantly scanning the ground, as long as it feels that there is a problem on the ground somewhere, or if it is a problematic ground in the detection record, it will immediately bombard. This rail cannon attacks the ground directly from space, which is too brutal.

Rail-mounted artillery shells with a speed of more than several hundred kilometers per second bring a first-class bright flame in the atmosphere, which is caused by friction with the atmosphere. But the speed of the rail cannon was too fast, and before the atmosphere could melt the projectiles, the powerful projectiles hit the ground.

These solid projectiles, at this moment, burst out with more power than ordinary missiles. After the railgun shell carrying a huge kinetic energy hits the ground, all the kinetic energy explodes instantly, and the energy that bursts in an instant can even melt rocks.

Each attack leaves behind a crater-like existence. Qin Fei looked at the nearest "crater", which was more than 100 meters deep and more than 300 meters in range; And that's not even counting the pit bottom, which has been re-covered by dust.

In the sky, streamers connect space and the earth like silk threads; It's just that every thread is a thread of death. You can constantly see the collapsed ground, and you can see the warriors of the Bosela civilization who have no choice but to rush out; And many of the mecha warriors of the Bosela civilization were killed by the railcannons as soon as they came out.

War has never been about mercy!

Mechwarriors are powerful, of course, but there is a premise - not alone! Otherwise, just like right now, under the lock of the rail cannon, the Mecha Warrior is just an alternative egg. The powerful ship can even lock on to a dozen mechfighters at the same time to attack.

The warriors of the Bosela civilization rushed out in a steady stream; If you don't rush out, the base will be bombarded by the rail cannon! This bombardment is not enough once, but over and over again, even if all the mecha warriors come out in some places, they still have to bombard.

The spaceship swept the planet over and over again, but on the side of the Bosela civilization, there were still a few bases that were dug deep enough to be attacked for a while.

And this is the task of the mecha warrior on the ground; But this mission is not to fight, but to scout.

The heavy soles of the mech's feet slammed on the ground, detecting the situation underground by analyzing the returning seismic waves; There is also the search for some caves hidden under the high mountains around the area; Once you find a hole somewhere, immediately contact the spaceship in the sky to attack, attack frantically, and will not stop without collapsing the ground.

During the reconnaissance, suddenly a team of mecha warriors of the Bosera civilization rushed out, they hid very well, and as soon as they rushed out, they fought with Qin Fei and the others. In this way, weapons in space are useless.

It's a pity that they picked the wrong object! Qin Fei lightly pulled out his long sword, and cut down a piece of mecha warriors with a few brushes; At the Olympic Games on the Raptors, Qin Fei was an invincible general; Now that they are even more powerful, these mecha warriors are not vulnerable at all in the face of Qin Fei, who is extremely close to the S-level.

As soon as the mecha warriors of the surrounding special combat teams were preparing to act, they saw Qin Fei's mecha blurry for a while, and the next moment the enemy came down en masse, and they were momentarily stunned - is this gap a little too big?

The search lasted five days, and it took almost three times to turn over the tiny planet; Then throw all the spacecraft, including the wreckage, into the distant gaseous planet, leaving no material behind; Then a few more squads were left to monitor the place; The large team immediately accelerated and rushed to the Starry Sky Gate.

By the time Qin Fei and the others arrived, it was already six months later; The universe is huge, and so is a small galaxy, and it's months to travel at a time.

At this time, the battle near the Starry Sky Gate was already fierce. There are only more than 50 warships left on the side of the Bosela civilization, and the earth civilization has also lost thousands of unmanned spaceships, more than 200 manned spacecraft, and more than 2,000 dead soldiers! These are all evolutionaries and the elite of society!

The reason why the losses are so heavy is also because the Bosela civilization has the initiative! In order to protect the Starry Sky Gate, the earth civilization is at an absolute disadvantage.

At this moment, the Bosela civilization played guerrilla warfare.

Fortunately, after all, the earth civilization has a local advantage, and a large number of fleets repeatedly dragnet searches in space, so that the guerrilla warfare of the Bosela civilization is not so smooth.

And the fierce battles for several months have also made the fleets of the Earth Civilization and the Bosela Civilization unbearable, especially the fleet of the Bocera Civilization that lacks supplies, and it is even a little unsustainable.

It's just that the earth civilization can't give up, and 200 million tons of rare materials are about to be delivered, and these resources will get the earth civilization out of the overstretched state! Some scarce mineral resources, such as palladium and other rare earth metals, have very little content in nature; And these resources are indispensable for space equipment and high-tech items. Now that the Earth civilization has to repair the solar shell on the one hand, and fight the Bosera civilization on the other, the demand for scarce resources has never been stronger.

Therefore, Xu Dongfang gave a death order, he must protect these 200 million tons of materials to reach the solar system, even if he fights all the spaceships in the Western Zhou Galaxy, he will not hesitate to do so!

In the darkness of space, another huge fleet "slowly" approached.

"It's reinforcements from Noah's system, reinforcements from India and West Asia!" With reinforcements arriving at this difficult time, the civilization of the earth is of course overjoyed.

As mentioned earlier, the starry sky gates here are two ultra-long-range starry sky gates connected to the solar system and the Miata civilization; And some of the starry sky gates that are close to each other are hidden near the living planets.

In terms of the Bosela civilization, seeing that reinforcements from the Earth civilization have arrived, everyone knows that the general trend has gone; In particular, General Federer Sem Mu could not hold on. Although the remaining fifty or so ships were still fighting, they were all wounded, and the laser reflective coating of all the ships had been damaged.

General Federer Sem Mu has finally decided to retire and return to their base to replenish supplies - for the time being, the Bosela civilization does not know that their lair has been controlled by the Earth civilization; However, the Bosela civilization has been operating there for more than 130 years, and there are indeed many places where supplies are stored that have not been discovered.

It's just that just when he was about to retreat, the probe of the Bosela civilization suddenly detected that the starry sky gate leading to the Miata civilization of the earth civilization seemed to be charging and the electromagnetic radiation was greatly amplified.

"It's not good, there are supplies sent from the Miata civilization!" General Federer's face changed dramatically, and he finally knew why the Earth civilization had been fighting so much in the past few months!

"General, it's too late to rest!" An adjutant next to him had a sad face, "It's time for us to fight hard!" ”

General Federer's face changed several times, and finally ordered, "Send a signal to the Motherland, this battle code name, eternal life." ”

"Yes!" The adjutant turned around and sent the signal out, and at the same time sent all the information out a dozen times in the form of electromagnetic waves. The universe is vast, and it is dozens of light-years away from the Bosela civilization; After so many years of transmission, the signal has degraded to an almost indistinguishable state.

For distant cosmic communication, the approximate direction must be calculated, and then the laser communication must be fired in a directional manner, or the electromagnetic pulse communication must be strengthened. But now the fleet of the Bosela civilization cannot be stopped at all, and can only emit electromagnetic waves outward; In order to ensure that the information is sufficient, it can only be repeated repeatedly, after repeating a dozen times, after a short pause, and repeating a dozen times.

This time, the signal transmitted is mainly ...... Note!

The code name "Eternal Life" means that all the warriors of the Bosela civilization have decided to die!

Similarly, when the electromagnetic radiation of the Starry Sky Gate was unconcealably amplified, Xu Dongfang also looked serious, "Everyone, the time has come to really work hard, no matter what, we can't let the Starry Sky Gate suffer a little attack."

The code name of this operation, The Great Wall! Use our spaceships and our flesh and blood to build a Great Wall in space! ”

Ships surround the perimeter of the Starry Sky Gate, as well as steel plates, aluminum plates, and even the wreckage of the spaceship, as long as any defensive items can be found, all of them are dragged over to defend them.

Further periphery, unmanned spacecraft and unmanned probes are constantly scanning for traces of the enemy.

Qin Fei and the others arrived at this time, and the spaceship and others did not have time to repair it, so they immediately entered the battle; Qin Fei and some other people who were destroyed by the spaceship temporarily entered some S-class spaceships with a lot of job demand, or quasi-S-class spaceships and took place.

Space is always so quiet, no matter how many wars there are, it cannot cause the slightest fluctuation in the universe.

The Starry Sky Gate has entered the countdown to opening, and the ultra-high pressure of hundreds of millions of volts provides strong energy for the Starry Sky Gate; But such a powerful energy also inevitably emits strong electromagnetic radiation. Under the observation of the probe, the gate of the starry sky during the activation process is as obvious as the sun!

Tension has risen, and a life-and-death showdown, perhaps even related to the future of the two civilizations, is about to begin! (To be continued.) )
