The door of his house was open this time, and it seemed that it was specially prepared for Shen Nan.

The living room is monotonous black and white, monotonous and old-fashioned, just like him.

Li Yang sat on the sofa, staring directly at the three bottles on the coffee table.

Seeing Shen Nan coming, he just casually pointed to the empty sofa on the side.

"Sit."

Shen Nan sat down and asked straight to the point, "How do you know?" ”

"Me?" Li Yang chuckled, "I was accidentally taken to live on the M7 Star by your good friend for a while...... Just recently came to Earth with you. ”

"You? Went to the M7 star? Shen Nan looked at him suspiciously.

The monitoring system of their M7 star is no worse than that of Earth, and it is impossible that there is no one who does not know about it, and this person has obviously lived in M7 for some time......

"So...... You've been hiding inside my ship? Shen Nan stared at the man in front of him in shock!

He had been hiding in his spaceship for so long, he didn't even know it......

No wonder in that short period of time, the materials in his spaceship were drastically reduced, and it turned out that they were all taken by this guy!

"Yes, all the time." Li Yang said without concealment: "Not only here, but also in your spaceship...... Saw that world pandemic. ”

Li Yang's eyelids drooped slightly, and there was no luster in his pupils, as if he had lost hope of living.

And recently, that hope has been dashed.

He pushed the three bottles on the coffee table, "These three bottles, you know." ”

Shen Nan looked at the bottle and nodded: "I know, and that day, the bottle that froze me and Shen Si is the same type." ”

Li Yang nodded: "That's right, it's the same type of bottle." ”

"So, what are you doing with this bottle?" Shen Nan turned his gaze to Li Yang and asked.

Li Yang crossed his fingers and stared at the bottle for a while: "Throw it into the sea, freeze all the bacteria and elements that may be pollutants, and make a natural marine ice reservoir." ”

The dream is great, but the reality is skinny!

Shen Nan chuckled: "Are you sure, this method is feasible?" ”

"Not sure...... Li Yang lowered his eyes: "That's why I called you back to discuss this matter." ”

"After all, you're the one who taught yourself environmental engineering on Earth! In just half a year, he got his doctoral diploma and made outstanding contributions in all major fields. The corners of Li Yang's lips hooked.

The dean didn't believe him, his parents didn't believe him, so he could only come to Shen Nan......

He was a witness to that catastrophe...... Even if everyone in the world doesn't believe him! But he Shen Nan, you must believe him.

"Indeed......" Shen Nanhao said modestly, "After all, I am a genius." ”

"So, genius, do you have any way to freeze those suspicious creatures living chemical elements." Li Yang asked.

"I'm a genius, yes, but I don't know everything. And the kind of approach you're talking about is simply not practical. Shen Nan shook his head and said, "Moreover, are you really sure that all the sources of pollution come from the ocean?" ”

Li Yang lowered his head silently when he heard this, he was not sure......

But his expertise can only investigate the water quality of the ocean, the soil and the atmosphere...... He doesn't have any use at all.

"So...... I just called the almighty Mayor Qi over to talk, didn't I? Li Yang lifted his eyelids slightly, he felt that Shen Nan must have a way to stop the outbreak of this epidemic: "Mayor Qi, but a genius!" ”

What the is this...... Do you want to kill him?
