Cataclysmic Era: I can unlock the tech tree

"What do you mean?"

Tang Wenshan frowned deeply: "Isn't this long-range communication?"

"Quantum action at a distance has been experimentally verified..."

Lu Yongchang shook his head meaningfully, interrupting Tang Wenshan.

"No, this kind of long-distance communication is just a trick."

"Mr. Tang, haven't you noticed that in our long-range communication system, each device can only communicate with its corresponding device?"

"A pair of entangled photons can only create a pair of long-distance communication devices."

"And these machines can only receive messages from the other side."

"Normally, communication devices never operate on a one-to-one basis."

Tang Wenshan's expression changed slightly.

Overwhelmed by the joy of the successful experiment, he subconsciously overlooked such an important point.

"Moreover, we must first deliver the corresponding terminal to the destination before we can conduct long-distance communication with the target location," Lü Yongchang continued. "This means that if we want to communicate with other civilizations, we can still only rely on electromagnetic waves, an extremely 'slow' means of communication."

"Unless we send over a quantum communication terminal first."

Tang Wenshan frowned even more deeply.

He pondered for a moment, then said in a low voice, "But... but this is a drawback of quantum long-distance communication, and we cannot avoid it."

Lü Yongchang didn't speak, but simply nodded silently.

Is there really no way to avoid it?

Thinking that according to the technology tree system, they were still at the lowest level, the first-tier civilization, a hint of bitterness appeared in Lü Yongchang's eyes.

Perhaps it's simply because human technology is too underdeveloped.

……

half a month later.

The Qinghai-Tibet Plateau, the Human Union Starship Base.

"Andrew?!"

Hong Fan's distinctive voice rang out within the base: "What are you doing here?!"

Upon seeing his former savior, Andrew's face immediately broke into a bright smile.

He laughed heartily, strode up to Hong Fan, patted Hong Fan's shoulder forcefully, and greeted Hong Fan in fluent Chinese.

"Brother Fan, have you eaten?"

Hong Fan: "...???"

Faced with such a down-to-earth question, Hong Fan replied somewhat awkwardly, "Yes, I ate."

"Hey, wait, didn't you go into hibernation? Where are your teammates?" Hong Fan asked again.

Logically speaking, an ordinary person should be on their way to the Kuiper Belt right now!

Suddenly, a possibility flashed through Hong Fan's mind.

"Could it be that you...?"

Andrew nodded smugly: "I've completed the training and am now a licensed starship pilot."

"Furthermore, Brother Fan, the higher-ups said they want us to form a team with you guys."

"Wait, wait." Hong Fan's mind was a little foggy for a moment. "You guys?"

"And another thing, I remember you said you were preparing to live a normal life? What's going on?!"

Andrew laughed heartily and put his arm around Hong Fan's shoulder: "Brother Fan, people change!"

"After going to Mars, we all had some trouble adjusting to the mundane life on Earth."

"Moreover, facing such a huge crisis in the future, we also want to protect ourselves and our families, so..."

At this point, Andrew shrugged and said, "The three of us discussed it and immediately agreed to apply for the Human Federation's starship pilot training course."

"I almost forgot!" Hong Fan's eyes flickered, and he quickly asked, "With something like this happening on Mars, are your family members alright?"

He waved his hand gently and said, "It's nothing!"

"As soon as the People's Federation was established, we brought them over immediately."

"They should be near Mars by now, right?"

"In a few years, I plan to go and awaken them myself!"

Hong Fan breathed a slight sigh of relief, and a smile appeared on his face.

That's a really good ending.

Just as Hong Fan was about to continue asking Andrew about the formation of the new team, a familiar shout came from the side.

"Andrew, what are you doing here?"

"We've been looking for you for so long, hurry up..."

Before Hong Fan could react, Andrew was already smiling and greeting the newcomers: "Bruno, Joey, look who I've run into!"

"...Hong Fan?!"

"Holy crap! Brother Fan!"

Two standard Chinese accents then rang out.

Seeing the two people rushing towards him, Hong Fan's lips twitched slightly.

To be fair, they've thoroughly figured out the culture of the Xia Kingdom.

After exchanging pleasantries, Hong Fan suppressed his smile and asked in a low voice.

"Andrew, what exactly did you mean by joining our group?"

Andrew shrugged, a look of confusion on his face.

"I'm not entirely sure either; that's the notification we received."

"According to the notice, we should still have tasks to perform at that time."

"Didn't you receive a notification?"

Hong Fan looked puzzled and slowly shook his head.

"never mind!"

He shook his head dismissively: "I guess the higher-ups haven't had time yet!"

"Come on, let me show you our team's dormitory."

"Let me tell you, you're in luck if you join our team."

"We're a veteran team after all, so the dorm environment here is top-notch!"

"I'm not bragging, it's definitely the best dormitory in the base!"

……

"Team Leader Bai, Wanyi, look who's here!"

Hong Fan pushed open the dormitory door and shouted loudly.

But when he saw the middle-aged man standing in the middle of the dormitory, his voice suddenly shrank several times.

"...Commander Qi, you're here too."

Seeing his two teammates standing obediently to the side, Hong Fan looked distressed and slunk into the dormitory.

As for the three people behind him, they stood dumbfounded at the door, not knowing what to do.

"Alright, stop pretending to be wronged." Looking at Hong Fan's drooping head, Commander Qi said irritably, "Do you think I don't know what kind of person you are, Hong Fan?"

"And you three outside, come in. We're here specifically for your sake."

Hearing this, Hong Fan visibly breathed a sigh of relief, then nudged Bai Yixuan beside him with his elbow and gestured towards the door with his lip.

Upon seeing Andrew and his two companions enter the room, Bai Yixuan and Xia Wanyi were visibly taken aback.

"You two should be considered old friends, so I won't go into too much detail."

Without giving the six men time to think, Commander Qi said directly, "From now on, the six of you will form a combat team and be responsible for piloting the Luan Bird Type I starship."

"The task is simple."

"You will need to cooperate with Professor Lü to complete an experiment. Professor Lü will explain the specific details of the experiment to you later."

"What you need to do is cooperate unconditionally."

"Did you understand?!"

Bai Yixuan and the other six men straightened up, stood at attention, and shouted in a deep voice, "Yes!"

"Mission accomplished!"
