Chapter 481: Visitors from the Pan-Galactic Alliance

Wrapped in red steel armor, Stark reached out his hand, aimed at the Warrior, and fired a shell, piercing the Warrior's armor to reveal the flesh and blood inside, before killing it.

……

Twelve Terminators aimed their palms simultaneously at the Warrior, firing particle beams from their hands, driving the Warrior back step by step. After one minute, the Warrior finally died from blood loss due to excessive wounds.

……

All sorts of scenes appeared all over the world. Although the speed of killing Warriors was fast, the progress of wiping them out was slow. Ten days had passed, and not even one-third of the Warriors had been eliminated, though most of the time was wasted on the road.

"Is it really okay to do this?" Ye Nan watched the footage coming in from around the world, his brows deeply furrowed. Because of the original strategy, the Space-Time Empire had slowed down the pace of clearing out the Zerg invaders, leading to tragedies appearing all over the world, mainly because these Zerg were extremely sensitive to the perception of living organisms.

"There is no other way," Ilis said helplessly. "I didn't know these Zerg would have such keen perception; even humans we couldn't find, they could ferret out."

Under satellite scanning, Ye Nan had once thought his Space-Time Empire had already unified all of humanity and that all survivors were within the Space-Time Empire. However, the arrival of the Zerg told him that he hadn't brought all survivors into the Space-Time Empire. There were still many survivors underground on Earth, and because they were underground, the satellites couldn't scan them.

Now, these survivors were being dug out by the Zerg one by one. Ye Nan did a rough count; in these ten days, thousands of people had perished under the Zerg, which was about on par with the number of Zerg they had wiped out.

"This cannot be blamed on you," Ilis said. "It is they themselves who refused to join the Space-Time Empire."

To protect the cities of the Space-Time Empire, Ye Nan not only issued orders warning them of the Zerg invasion but also prioritized clearing out Zerg that landed near the cities. To this day, not a single citizen of the Space-Time Empire had died under the claws and teeth of the Zerg; those who died were almost all humans hiding underground.

They hid underground, yet were found by the Zerg and killed one by one.

"However, the ability of these Zerg to sense life is indeed powerful. If we can crack their secret, perhaps it will provide great help for us to search for survivors in the future."

In front of these Zerg, no matter how deeply you hide, as long as you are human, you will be found by them. Once or twice might be a coincidence, but since all Zerg had this ability, it was certain that the Zerg possessed this capability.

And this ability was a disaster for any civilization, because in this way, trying to preserve a spark of life under Zerg attack would be a very difficult thing.

"Judging from the fact that the Zerg can find us, they definitely have this ability, but this ability should have a distance limit. Otherwise, they wouldn't have only come now," Ye Nan said.

If the Zerg's sensing of living organisms had no limits, I fear this Earth would have fallen into the hands of the Zerg at the very beginning of human birth, rather than waiting until now to come.

"Can you find the direction the Zerg came from?" Ye Nan asked again.

"I can't find it. It suddenly broke in when Earth and Mars were about to intersect. Where it specifically came from, the satellite simply cannot detect; I only know a rough direction," Ilis said, shaking her head. If it were inside Earth, she could calculate where it might have come from through countless operations. But space is simply impossible; even if she ran calculations non-stop for a year, she couldn't calculate where the Zerg came from. After all, the vastness and unpredictability of the universe determined its eerie variability.

"Then what about the defensive turrets? How are the turrets for defending outer space coming along?" Ye Nan asked again. This time the Zerg meteorites arrived, perhaps next time more will come; this time the Zerg meteorites fell in the wilderness, perhaps next time they will fall on the cities; this time the Zerg meteorite impact on Earth didn't bring climate change; perhaps the next Zerg meteorite attack will punch a hole in the Earth.

This time's luck was due to the enemy's strategic needs, but Ye Nan couldn't expect the enemy's strategic needs to never change for a lifetime, so he had to strengthen Earth's defenses to allow it to defend against enemies from outer space.

"Regrettably, ten days of time only allowed the factory to build two turret prototypes." A model of a tank appeared next to Ilis.

This tank was silver-white and didn't look much different from a regular tank, except its barrel was slightly longer. The barrel extending from the tank's steel body was nearly twice as long, and the muzzle was also noticeably thicker.

"S-15 model tank. I originally intended to use it to build a turret-type Terminator, but modifying it into an anti-aircraft weapon now is also not bad," Ilis said. "Because it is specifically aimed at Zerg meteorites, I strengthened its firepower and cut out other small weapons."

Although weapons are mostly universal, when applied to different uses, some minor changes are still needed.

In the original design, the turret Terminator was also supposed to have two small secondary guns and a missile launcher, but now they were all cut out by her because, for dealing with Zerg meteorites, small secondary guns and missile launchers were of no use.

"Is this thing really useful?" Ye Nan looked at the S-15 model tank in front of him suspiciously, feeling some doubt.

After analysis by the Imperial Research Center, the surface of Zerg meteorites is a very special substance. This substance is extremely hard in texture, and even in intense friction with the air, it won't lose much material.

Facing this mysterious substance from outer space, can the S-15 model tank really blast it open?

"There is absolutely no need to worry." Ilis also understood Ye Nan's concern, but the data for the S-15 model tank was completely targeted at Zerg meteorites and was sufficient to crush them.

"This is a simulation experiment." Ilis snapped her fingers, and the screen instantly turned into a space scene with a Zerg meteorite flying over from space.

At this moment, the satellite also captured the trail of the Zerg meteorite, and a sharp alarm sounded. On the space base, the S-15 model tank revealed its sharp fangs. It adjusted its angle, aimed at the Zerg meteorite, and a beam of light flew out from inside. With a 'Boom—', the Zerg meteorite was blown into fragments in space.

"Although this is just a simulation experiment, all the data is flawless, and the error in the test is less than ten percent. The precision is very high," Ilis said.

Before the apocalypse, the military boasted in simulations that the error was less than one percent, or even 0.1 percent, which was an imprecise attitude. In Ilis's view, these were all manifestations of arrogance.

Admittedly, in experiments, perfect data support can make the results of simulation experiments infinitely close to reality, but in true reality, there are all kinds of accidents.

For example, the Zerg inside manipulating the meteorite to slow down or speed up, or because of other meteorite fragments, and special unexpected discoveries like solar storms or cosmic ray bursts, would all lead to deviations in the results. If these factors cannot be added into it, the so-called experiment is simply a pile of data garbage.

"So powerful?" Ye Nan asked.

In the simulation experiment, the S-15 model tank took out the Zerg meteorite with just one shot. This powerful destructive force made Ye Nan marvel.

Of course, he wouldn't suspect that the experiment was too exaggerated, because he understood that in such simulation experiments, the data inside was real. If the firepower of the S-15 model tank was so fierce in the experiment, it would be just as fierce in reality.

"But is that blue beam a particle cannon?"

"It is a plasma beam cannon," Ilis replied. "It is essentially different from a particle cannon. A plasma beam cannon has more destructive power than a particle cannon."

Ding! ……

A sharp alarm suddenly sounded, causing Ye Nan to stand up abruptly from his seat. "What's wrong?"

Ye Nan, who had just been discussing weapons with Ilis, had his expression change uncertainly at this moment. "Is it Zerg meteorites attacking again?"

The previous wave of Zerg meteorites hadn't even been cleared up yet; if another wave came, Ye Nan feared he wouldn't be able to eat or sleep well.

One can imagine that the power of the first probe is always the weakest, and the second wave is the real start of the war. Once the battle begins, it is inevitable that Earth will suffer harm, and at this time, the S-15 model tanks hadn't been deployed into space yet.

"It's not Zerg meteorites." A picture appeared on the screen. "It is an alien warship. Currently, I don't know if it is friend or foe, but I estimate this should be the Pan-Galactic Alliance mentioned by the Cosmic Heavenly Demon."

"Pan-Galactic Alliance!" Ye Nan murmured, the words of the Heavenly Demon Queen appearing in his mind. A smile quickly appeared on the corner of his mouth. "Has it finally arrived?"

A person closing themselves off is ultimately not the way to go, and neither is a civilization, especially a civilization like the Space-Time Empire that is gradually becoming deformed. Being able to communicate with alien civilizations and acquire technology is a fantastic idea for Ye Nan.

In fact, Ye Nan also discovered that the Space-Time Empire was lopsided in technology: biological and viral technologies had made great progress, but propulsion systems and quantum communication were progressing very slowly.

The Space-Time Empire was like a person walking on two legs, one leg constantly growing taller while the other couldn't keep up with the growth speed. Gradually, it became a cripple.

And if he could communicate with aliens, then the other leg could also grow taller. Gradually, it would become a normal person, a normal person who could stride ten or eight meters in a single step.

"Please don't be so happy." Ilis poured cold water on Ye Nan. "That they are people from the Pan-Galactic Alliance is only our guess. We have no way of knowing who they really are, and people from the Pan-Galactic Alliance won't be that kind-hearted. After all, it is composed of members of different civilizations."

"I understand." The thoughts in Ye Nan's heart didn't disappear much, but under Ilis's reminder, he became much more cautious. ===== CHAPTER 482 =====
