Chapter 620 Mysterious Building

After several hours of fighting, the Empire's biochemical control forces finally succeeded in clearing out the infected wandering on the city roads after sacrificing 30% of their combat robots and armored vehicles.

The next task was to enter each building and eliminate all the infected hidden in the building.

However, after entering each building, the Empire's troops did not find any infected.

"Room No. 1 is safe!"

"Room No. 2 is safe!" Dozens of soldiers wrapped in isolation power armor cleared the entire building and gathered on the rooftop under the escort of combat robots.

"Report to the headquarters, no infected people were found in Building No. 13!" A soldier connected to the headquarters' communication channel and reported.

"The headquarters received it, check the next building immediately!" Soon, the command from the headquarters came from the terminal.

The cleaning team activated the jet backpack on their backs and jumped towards the building next to them.

At this time, there was no joy in the headquarters because no infected people were found.

A dull atmosphere enveloped the command hall of the headquarters.

"Sir, we have roughly counted the number of infected people we have killed. We should have killed about 40% of the infected people on the entire planet, and the remaining 60% of the infected people are still missing."

"They may have left the city through some channels." An officer reported carefully.

The commander slammed the table angrily: "Keep looking, I don't believe these infected people can fly away with wings!"

At this time, the commander always had an indescribable feeling, he felt like there was a conspiracy.

A few hours later, the last building in the city was searched, and no trace of infected people was found in all the buildings.

The survivors were also rescued intact by the soldiers. These survivors have been tied up and concentrated in several buildings. Before finding a way to determine whether they are infected with the virus, these people will lose their personal freedom to prevent the virus from spreading further.

"Sir, we have exhausted all the means we can use, and no trace of infected people has been found."

At this time, a soldier suddenly raised his hand and obviously had something to say to the commander.

The commander nodded gently to the soldier and said, "Tell me, what's the matter?"

"Report to the commander, when I was searching the blueprints of this city, I found a complex underground pipeline system."

"This pipeline includes the drainage and water supply functions of the city. Because it was designed to prevent it from being used by people with ulterior motives, the entire system is composed of small pipes."

"Therefore, our troops subjectively ignored these pipes, thinking that ordinary people with ordinary body sizes could not pass through these pipes."

"But we ignored that the body size of these infected people can be changed!" The soldier said and sent a map of the underground pipeline distribution to the screen in the command hall.

"Where do these pipes eventually lead to?" The commander stood up and walked to the screen, looking at the countless pipes stacked on top of each other and asked.

The soldier hurriedly searched on the blueprint, and soon he looked up and replied loudly: "Commander, these pipes finally converged to the sewage treatment facilities outside, where the sewage will be converted into clean water and discharged into an artificial lake."

"This artificial lake is also where several nearby cities concentrate on discharging purified water!"

The commander gently touched his chin.

"Have the residents in these cities been infected with the virus?" the commander asked the officer beside him.

"Yes, these cities are the most seriously infected cities on this colony planet." The officer hurried back.

"Immediately send the fleet to the sky above this artificial lake!" The commander suddenly punched, and he now knew where these infected people were hiding.

Next to the artificial lake at this time.

Because of the Empire's advanced sewage purification technology, the purified water discharged from the sewage treatment plant is even purer than the lake water in nature.

And some people have set their sights on the economic benefits that this artificial lake can bring. These people have contracted this huge artificial lake that is like a small inland sea to breed some fish species with high water quality requirements.

But that night, there was a sudden sound of rushing water in the artificial lake. Worried about problems with the fry they raised, the farmers hurriedly came to the lake with rifles from their homes.

The lake surface, which should have been calm, suddenly rolled up, and countless bubbles rose from under the water.

"What happened?"

"I don't know, is there a problem with the sewage treatment plant?" The farmers talked about it.

At this moment, a spire made of flesh and blood suddenly rose in the center of the huge lake.

The spire rose little by little, and in tens of seconds it had stretched hundreds of meters upward.

The clear lake water slid down from the spire, and through the reflection of the lights by the lake, people could even clearly see the tiny tentacles dancing on the spire!

"Monster!"

"The Zerg are invading!" People shouted in panic and fled in all directions, while the tower in the lake was not affected at all and continued to rise.

A few seconds later, the tower suddenly rose into the air, and the tentacles below the tower were still waving in the air.

The water droplets attached to the tower sprinkled into the lake, making a roaring sound like a waterfall.

Because the tower quickly took off, it left a huge circular pit in the lake, and the water around the circular pit quickly rushed to the middle.

At this time, the satellite in the orbit of the colony star had already discovered the tower that was rising rapidly.

But by the time they reacted, the tower had passed through the atmosphere and entered the orbit of the colony star.

"Send warships to destroy this building immediately!" The commander finally knew what he felt was wrong!

The Zerg spreading this virus within the empire is not a real killing weapon!

The reason why they fought head-on with the imperial troops was just to attract their attention and buy time for the actions of the 60% infected people!

And they took advantage of this gap to complete their real purpose and formed the infected people into the Zerg building that is now floating in the orbit of the planet!

"Report this matter to His Majesty the Emperor immediately!" The commander wiped his cold sweat. He didn't expect that the Zerg would go to great lengths just for this building of unknown purpose.

Although I don't know what its function is, it is definitely not a good thing. The value of this thing is definitely more important than a colony of the Sith Empire!

Otherwise, why don't they continue to spread the virus, but gather these infected people together?
