Cataclysmic Era: I can unlock the tech tree

Mars.

Bai Yixuan sat in the driver's seat, looking at the radio equipment in front of him with a bored expression.

"Do you think Professor Lü will let us go to rescue him?"

Xia Wanyi, standing to the side, frowned slightly.

"uncertain."

"This matter is not up to Professor Lü to decide."

"After all, this involves the United States, and the specifics depend on what the Speaker of the House thinks."

Upon hearing this, a hint of reluctance appeared in Hong Fan's eyes.

"But if we don't save them, what will happen to them..."

Bai Yixuan sighed softly, his eyes filled with melancholy: "That depends on Professor Lü."

"As someone who works in the aerospace industry myself, I also hoped to save them."

Just as Bai Yixuan was about to change to a more comfortable sitting position, the wireless device suddenly rang.

"laugh……"

A familiar electrical sound rang out.

Bai Yixuan suddenly sat up from his chair, his gaze fixed intently on the wireless equipment in front of him.

"Calling Mystic Maiden Number Two, calling Mystic Maiden Number Two..."

"Initiate the rescue mission immediately! Repeat, initiate the rescue mission immediately!"

Lu Yongchang's voice was slightly distorted, but to the three astronauts it sounded like heavenly music!

Bai Yixuan's eyes showed a hint of excitement as he reached out, clenched his fist, and swung it forcefully in the air.

"Everyone, let's get ready to go!"

……

Bottom of the ZHZ72 meteorite crater.

Sunlight shone through the slightly murky Martian atmosphere, illuminating the bottom of the crater riddled with drill holes.

A jet-black spaceship slowly closed its two open hatches.

The next moment, several dark blue flames appeared at its base, propelling the Mystic Maiden II slowly into the air.

"Pathfinder, please respond!"

Bai Yixuan, slightly excited, adjusted the radio frequency and sent a call to the Pathfinder Mars capsule more than a thousand meters away.

"We're here!"

……

Pathfinder return capsule.

The atmosphere was very oppressive.

The three astronauts sat in their seats with long faces.

"Sigh..." Andrew sighed deeply and looked up at the time again.

"Two hours have passed."

Will they come to rescue us?

Bruno shook his head in frustration.

"Probably not."

"You could tell from their attitude towards us from the very beginning."

"The divide between nations is destined not to be resolved so easily."

Hearing this, Joey also sighed deeply.

At first, the three of them had high hopes.

But as time went by, everyone's hopes were gradually worn away.

"What if..." After a moment of silence, Bruno took a deep breath, "What should we do if they don't come to rescue us?"

no respond.

But a hint of death appeared in the eyes of all three.

"laugh……

"Pathfinder, please respond!"

"We have arrived above the Mars module. Repeat, we have arrived above the Mars module!"

The three astronauts suddenly looked up, a look of ecstatic joy rising deep in their eyes!

The speaker's voice sounded familiar.

If they remember correctly, it should be the astronaut who "threatened" them not long ago.

But now, that originally "annoying" voice sounded like heavenly music to the three astronauts!

Andrew reached out and grabbed the microphone in front of him, his voice trembling slightly, even tinged with a hint of crying.

"Thank you, thank you all!"

As he spoke, Andrew covered his face with his hands, and hot tears streamed down his cheeks.

A hissing sound rang out. "You're too kind. The Xia Kingdom will never abandon any human being!"

Upon hearing these words, the tears in Andrew's and the other two's eyes became even hotter.

They never expected that, in their moment of despair, the Xia Kingdom on the other side of the strait would extend a helping hand!

"Thank you, thank you..."

Andrew didn't know what to say, so he just gripped the microphone tightly and kept thanking them.

A few minutes later, the three of them gradually calmed down.

"What should we do?"

Andrew wiped away his tears and said, his voice choked with emotion.

Soon, a response came over the radio.

"Just come out, we'll land immediately."

Upon hearing the words on the radio, the three astronauts hurriedly put on their spacesuits and helmets, and crawled through the slightly narrow passageway into the airlock inside the return capsule.

……

The Pathfinder return capsule hatch slowly opened.

Andrew was the first to emerge from the return capsule.

He stared blankly ahead.

He could swear that he would never forget this breathtaking scene for the rest of his life!

A massive, dark black spaceship, its underside spewing eerie blue flames, slowly landed on an open ground a few dozen meters away from them.

Although the spaceship has a rectangular structure, it is filled with an unusual aesthetic.

At the same time, under the force of the engine's exhaust flame, countless reddish Martian dust particles were kicked up from the dry Martian ground.

Martian dust filled the air, turning the already slightly murky atmosphere a deep crimson.

Crimson, deep blue, and jet black blended perfectly before him, creating a stunning and breathtaking scene.

In the painting, a bright red flag was deeply imprinted in their hearts.

"Jesus..."

Bruno's sigh came through the radio.

Clearly, Andrew's two teammates were also stunned by the shocking scene before them.

The three of them stood there, dumbfounded, in front of the return capsule.

"My God... is this really technology that humans possess...?"

Joey muttered to himself.

As soon as she finished speaking, a stream of air shot out from the side of the Mysterious Maiden No. 2, stirring up a cloud of sparks and dust.

Then, the hatch on the side of the Xuan Nu II slowly opened.

Three figures dressed in silver-white spacesuits appeared before the crowd.

Andrew's eyes flickered slightly.

The spacesuits worn by the Xia Kingdom are at least several times lighter than what they are wearing!

If the US spacesuit looks like a 400-pound fat person, then the Chinese spacesuit looks like a normal 120-pound person.

"Hello...you guys..."

As the three astronauts from Xia Kingdom slowly approached, Andrew swallowed hard, nodded slightly, and then greeted them over the radio.

"Hello, we're here on a rescue mission!"

As he spoke, Bai Yixuan and the other two stood up straight and gave a neat military salute.

Seeing this, Andrew and his two companions hurriedly returned a less-than-perfect military salute, and then bowed to Bai Yixuan and his two companions.

Thank you.

"What's the point of being grateful... it would be more practical to grant the Mars capsule data access permissions..."

Hong Fan pursed his lips and said in a low voice.

But he clearly forgot that the current radio channel is not the team's voice chat.

Bai Yixuan's lips twitched violently, and he hissed, "Hong Fan! What are you saying?!"

He turned his head and glared at Hong Fan while secretly feeling relieved.

Luckily, Hong Fan spoke in Chinese just now, otherwise...

"Just now, you said you wanted data access to the Mars capsule, right?"
