Such a livable environment has a very high probability of developing into a civilization!

A synthesized electronic voice quickly announced: "The dispatched probes have completed detailed exploration of the six planets."

"To date, no signs of life have been found on the surfaces of any of the six planets."

"but……"

Lu Yongchang's eyes flickered slightly, and he stopped looking up the data.

"But?" He frowned slightly and asked in a low voice.

"A year ago, the probe discovered traces of biological activity and fossils in the Kepler 452b strata."

"Hiss!" A collective gasp rippled through the command center.

"A biological fossil?!" Mao Zhengzhi excitedly stood up from his seat and asked eagerly.

"Has it been tested? When did this organism come from?"

"Preliminary test data show that these organisms lived 500 million years ago."

"...500 million years ago?"

Zero's answer poured cold water on Mao Zhengzhi's enthusiasm.

Five hundred million years.

It's been too long.

It grew long enough to extinguish any illusion.

"What's the reason?" Fang Xu's expression gradually turned serious. "What caused their extinction?"

"I think it's the greenhouse effect."

Lu Yongchang stretched out his finger and gently tapped one of the data points in the holographic projection.

Carbon dioxide concentration.

"It's a bit like Earth that's becoming Venusian."

Lu Yongchang gently stroked his chin and said softly.

P.S.: Thanks to Solar Leap for the amazing certification!
