This was an unforgettable lesson for Theresa and Tesla.

A tutorial titled "Interstellar Civilization War" taught by Fang Zheng.

After obtaining the coordinates of the aliens' home planet from them, Fang Zheng immediately dispatched Sirius to conduct reconnaissance, and then activated the induction field again. However, this time, it was not only the Blue Fleet that came to the aliens' planet - but also the murderous Zerg army.

What followed was a ruthless massacre.

The alien fleet was reduced to wreckage under the bombardment of the blue fleet. Countless swarms of insects fell from the Leviathan to the ground, launching a terrifying and crazy attack on the entire planet. Standing on the bridge, Theresa could even watch the planet in front of her gradually turn from yellow to bright red...

“It feels like a dream…”

Looking at the planet in front of her, Theresa couldn't help but sigh.

"A civilization is clearly being destroyed in a war, but for some reason, I still don't feel the reality at all..."

"This is what war looks like under the development of civilization."

Unlike Theresa, who was full of emotion, Tesla just pushed up his glasses.

"In ancient times, we fought in the battlefield, holding swords and spears. We could see our colleagues or enemies being killed. The tragic state of their bodies, the wounds pierced by bullets and bombarded by shells, all of which made people feel the cruelty and horror of war. But now, we are just standing here, looking at the planet in front of us. For us, no matter how much loss there is below, it is just a string of numbers at the macro level. Of course, we can also imagine how those terrible insect swarms kill people in the sky, but as long as we don't see it with our own eyes, we won't have too many feelings."

Listening to the conversation between the two, Kiana and the others stood there, looking at the planet in front of them without saying a word. On the way here, Fang Zheng had cracked the database of the aliens. Therefore, they also knew that many of the alien soldiers they had faced before were actually tribesmen from the civilizations they had conquered and destroyed.

The aliens attacked those people's planets, destroyed their civilizations, plundered their Honkai energy, and controlled and used them as slaves and soldiers - these alone were enough to make the girls stand against the aliens.

If it was Yui Kotegawa or Haruna Sairenji who were here, even if they knew the threats from the Outer Worlds, they probably wouldn't have the heart to watch them being completely destroyed. However, Kiana and the others were warriors after all, and since they were warriors, they naturally wouldn't have any sympathy for such an evil and terrifying enemy.

Facts have proven that the people in the sky were not able to stop the power of the Zerg. Although they sent out many powerful beings with powers similar to those of the Herrschers to face the Zerg's attack, this level of power was completely meaningless in the face of orbital bombardment. Even if they had powers similar to those of the Herrschers, when the artillery fire roared down like a meteor, being blown to pieces was their only fate.

Fang Zheng did not intend to leave the people in the sky alive. Because the human civilization in this world was too weak and did not have the qualifications to swallow up the people in the sky. If he left the people in the sky alive now, it would not be long before the people in the sky would turn around and swallow up the earth.

So while attacking the home planet of the People in the Sky, he also ordered the Zerg to expand again and attack all the planets where the People in the Sky were located and completely annihilate them - this was something the Zerg was very familiar with.

Soon, the main force of the Celestial People was defeated, and Theresa took Kiana and the others to the Celestial People's home planet to search for some necessary information and items.

After all, the Zerg have no idea what humans are planning to research. In their view, everything left behind by the people in the sky is worthless and only deserves to be devoured and assimilated.

Therefore, if you don’t want those things to be eaten by the Zerg, you still have to search for them yourself.

So Fang Zheng handed the matter over to Tesla and Theresa, and went to sleep yawning.

When Fang Zheng woke up, several hours had passed.

He stretched himself and walked out of the room. Then Fang Zheng curiously saw Tesla sitting on a chair not far away, looking out the window with a can of beer in his hand.

"Hey, what are you doing?"

Fang Zheng walked up and greeted Tesla. Hearing Fang Zheng's voice, the red-haired girl with twin ponytails turned around and looked at Fang Zheng.

"Ah, Mr. Yuki..."

"Didn't you say you wanted to study the technology of the people in heaven? Is there any result?"

"Something."

When talking about his profession, Tesla immediately perked up.

"The way the people in the sky use Honkai energy is completely different from ours! We originally thought that the people in the sky used Honkai energy more like physical enhancement or weapon development, but in fact they chose a completely different path, which is to control Honkai energy through mental fusion!"

"Spirit?"

"Yes, this is really a completely new direction! The flesh and the machine have their limits in the end, but if you control the Honkai energy with your mind, you can reach a very high limit. And they also use a method to filter out the Honkai information in the Honkai energy, making it a pure energy source..."

“Sounds similar to the Githyanki.”

After hearing Tesla's explanation, Fang Zheng thought of the Githyanki people in the Star Realm. Those guys also liked to dig up the corpses of gods in the Star Realm, and then extract the divine blood from them, filter and purify it for use... Well, the Githyanki people were also a very aggressive race in the Star Realm.

"Isn't this a good thing? Why are you acting so sad?"

Fang Zheng also reacted at this time, but he was still very curious. You know, just now when he saw Tesla leaning against the window with the image of a melancholy literary girl, he thought her research was not going well.

"No, I was just wondering...will we go down this path as well?"

As he spoke, Tesla turned his head again and looked out the window at the planet which was now bright red.

"According to the records, the people in the sky's desire for Honkai energy is actually the same as our human need for energy. Their technology, civilization, everything is built around Honkai energy. And the greater their power, the more Honkai energy they need. Therefore, they will attack other civilizations and extract their Honkai energy for use..."

Having said that, Tesla suddenly raised his head and drank the beer in the can in one gulp.

"I'm thinking now, do we have to go down this path too? Although this problem may be too far away for us now, in another hundred, two hundred, or three hundred years, perhaps humans will be like these people in the sky, because they don't have enough Honkai energy and will turn to invade other civilized races. After all, there are many wars for resources in human history."

"Learn from the good and let go of the bad."

Fang Zheng shrugged and sat opposite Tesla.

"Moreover, as long as we master this technology, even if we don't circulate it, someone will probably think of the same thing in the future."

"Yeah... maybe someday, an alien civilization will suddenly appear and completely destroy us who have done so much evil, just like this."

"Perhaps."

Fang Zheng shrugged his shoulders, then stared curiously at the beer can in Tesla's hand.

"Where did you get the wine?"

"hey-hey……"

Hearing Fang Zheng's question, Tesla smiled triumphantly, then she snapped her fingers, and then Fang Zheng saw the mecha standing next to Tesla open, revealing the inside...

"Small fridge?"

"Yes, there is everything in here, red wine, beer... do you want some?"

As he spoke, Tesla took out two cans of beer from the small refrigerator in the mecha cabin again, but Fang Zheng didn't care about it at all.

"Give me a can."

For Tesla, this was something she had never thought of. She had never thought that one day she would be in the universe, in a battleship, and personally experience a space war. She could even obtain records, research, and technology of the Honkai energy of alien civilizations.

This also made her extremely excited, and she had a lot of ideas in her mind. Unfortunately, Einstein, who could share all this with her, was not here. Tesla was also very excited to catch Fang Zheng at this moment. While drinking beer, she talked to Fang Zheng about her thoughts, including her thoughts on the technology of Honkai energy, her imagination about the future of mankind, and some thoughts she got from the records of these aliens...

Because he was too excited or drank too much, Tesla himself didn't know when he became drowsy and lost consciousness.

When she opened her eyes again, the first thing she saw... was the unfamiliar ceiling.

"Ouch... my head hurts..."

Tesla frowned and reached out to press her forehead. She felt a burst of pain in her head and her whole body was sore and weak.

"I wouldn't have drunk so much..."

Tesla turned her head away while muttering - and then she was completely stunned.

Beside her, Fang Zheng was lying there, soundly sleeping, and - he was not wearing any clothes.

"Why?"

Tesla was subconsciously startled and sat up quickly, and the hangover feeling in her mind dissipated a lot. She realized at this time that she was not wearing any clothes. The white shirt, suspender skirt and leather shoes she usually wore were scattered not far from the bed. She was only wearing a white silk silk - from the holes on it, it was obvious that the white silk had lost its original function.

“…”

What is going on?

Looking at this scene, Tesla was completely stunned.
