As soon as he left the laboratory door, Cao Liangcai saw Lu Yongchang, who looked gloomy and frowned, staring at the holographic projection.

"Professor Lu?"

Cao Liangcai called softly.

Lu Yongchang withdrew his gaze and turned to look at Cao Liangcai.

"Lao Cao."

Lu Yongchang's voice was extremely heavy: "The problem is big."

The muscles on both sides of Cao Liangcai's cheeks trembled violently twice, and his lips trembled as he said, "Professor?"

"Didn't you just say..."

Lu Yongchang slowly shook his head.

"That just stabilizes people's hearts."

"We just won the war, and everyone finally has some hope. If something happens again, I'm afraid..."

Cao Liangcai understood.

Lu Yongchang continued: "At present, the situation of Ross 154 is very similar to that of the Sun and Proxima Centauri."

"It's like something is absorbing a lot of energy."

"As a result, the chromosphere experienced violent fluctuations, causing it to erupt in extremely abnormal brightness."

"Then...can we change to another star system?" Cao Liangcai asked in a low voice.

Lu Yongchang shook his head.

"Ross 154 is the most suitable star system for human development within fifteen light years."

He added again: "Given our sailing capabilities, it is also our only option."

Cao Liangcai's face suddenly turned ugly.

"The main reason for calling you out is for one thing."

Lu Yongchang lowered his voice and said: "Build two sets of interstellar detectors."

Cao Liangcai was stunned: "Two groups?"

"Is it to increase the success rate?"

He couldn't understand Lu Yongchang's approach.

"Not really."

Lu Yongchang quickly shook his head: "One of the groups does not require too many detection functions."

"It will be sent to the solar system and used as an information relay station."

"We can no longer expose our coordinates."

"If Ross 154 really has an advanced civilization, let it go to the solar system to find us."

Cao Liangcai suddenly realized it and nodded repeatedly: "Okay, leave it to me."

“The Proxima Centauri civilization’s interstellar detector manufacturing technology is very good.”

"I estimate that the design drawings will be completed soon."

Lu Yongchang pondered for a moment and then added again: "That's right."

"Put nuclear torpedoes in every detector for me."

"In case of an accident, the self-destruction program will be started directly."

As soon as he finished speaking, Lu Yongchang heard a burst of noise coming from the laboratory through the wall.

If he heard correctly, it should be cheers.

He frowned.

"what happens?"

As he spoke, he looked at the holographic image around him.

When he saw the steadily declining data, his pupils shrank suddenly.

"this……"

Did he really fall for what he said casually?

Lu Yongchang quickly turned around and walked towards the laboratory door.

"professor?"

Cao Liangcai's voice was somewhat relaxed: "Will the interstellar probe still be built?"

Lu Yongchang paused: "Of course."

"We need to have a full understanding of the Ross 154 star system."

…

The laboratory door slowly opened.

Fang Xu is still the first person to discover Lu Yongchang.

His face was full of joy and he shouted loudly: "Yongchang!"

"You were right!"

"Ross 154 has begun to recover!"

Lu Yongchang looked at the steadily descending curve in the holographic projection in disbelief.

There were cheers and celebrations all around.

But his heart felt cold.

How abnormal!

His intuition told him that things were definitely not that simple.

"Yongchang?" Fang Xu noticed Lu Yongchang's unusually solemn expression, walked quickly to his side, and called in a low voice, "Is there any problem?"

Hearing Fang Xu's voice, his eyes moved slightly: "Not yet."

"Let's see how the data changes first."

"I always feel that things won't be that simple."

…

Half an hour later.

Looking at the data that returned to normal, Lu Yongchang took a long breath.

He looked confusedly at the holographic projection directly in front of him, which displayed gently fluctuating detection data.

Was he really wrong?

But the data fluctuation pattern just now...

Lu Yongchang suppressed the confusion in his heart and walked towards Cao Liangcai who was standing aside.

"Lao Cao."

"The manufacturing task of interstellar probes is given top priority."

"You can put everything else aside."

Cao Liangcai nodded silently.

After the explanation, Lu Yongchang still felt a little uneasy.

"Zero, add radio telescope array."

"Conduct round-the-clock detection of Ross 154. If any abnormality is found, report it to me immediately."

Zero responded quickly: "Okay, Professor."

…

Time passes day by day.

A new radio telescope array was also built and pointed at distant Ross 154.

Under Zero's control, countless radio telescopes and optical telescopes receive information from 8.24 light-years away at all times.

At the same time, two sets of interstellar detectors have also entered the manufacturing stage.

Influenced by the manufacturing technology of the Proxima Centauri civilization, these two sets of interstellar detectors were also made into spheres.

The diameter of a single detector reaches 10 meters.

Each set of detectors consists of five individual detectors.

These five detectors have the same structure and the same function - to observe and detect stars at close range.
