It's reasonable for me to have a two-way foil for a second-level civilization, right?

"One, replay the surveillance video."

Zhao Zijie said in a deep voice.

The video was quickly retrieved and projected on the transparent masks directly in front of the two helmets.

"This is the picture from an hour ago." One's voice came from the earphone.

In the video, more than 100 jellyfish sink quietly to the bottom of the water.

It is the same state as when it was first placed in the pool.

"This is the picture from 10 minutes ago."

The recording starts to speed up.

A jellyfish located in the center of the bottom of the pool suddenly twitched, and a lump of light yellow substance slowly overflowed from its surface.

After a few minutes, the jellyfish floated from the bottom to the surface.

This seemed to be a signal. In just a few minutes, almost all jellyfish entered the countdown to death.

After watching the entire video, Zhao Zijie looked gloomyly at the pond full of jellyfish corpses.

"One, haven't they been moved these days?"

Gao Yang's questioning voice suddenly sounded.

"Yes." One said without any hesitation, "There is hardly any activity."

Problem found!

……

The next day.

Lu Yongchang, who was on Mars, just came to the office when he heard the bad news from Titan.

"What?"

"They're all dead?!"

"No activity before death?!"

"Is there something wrong with the simulation environment?"

Immediately, Lu Yongchang set his sights on the simulated environment in the breeding room.

"Professor, there is nothing abnormal about the environment in the breeding room." Zero said while presenting various data in front of him, "On the contrary, it perfectly restores the environment on the surface of Titan."

"What about the sea water?" Lu Yongchang frowned, "Not enough hydrogen? Can't breathe?"

"Basically there is no such possibility."

Zero rejected his guess again: "The sea water in the pool will automatically circulate every 2 hours."

"The extraction device will extract fresh seawater from the surface layer of the methane sea."

"also……"

"and many more!"

Lu Yongchang suddenly said, "What did you just say?"

"Fresh seawater on the surface?"

"Yes, Professor." Zero said methodically, "The pumping pipeline goes deep into the sea about 3 meters."

Hearing this, he patted his thigh hard.

"I see!"

"It must be the problem of sea water!"

"Zero, inform Zhao Zijie to send a few robots to the bottom of the sea to check the situation."

Thinking of the spectacular scene of the last trapping operation, Lu Yongchang added hastily: "Zero, help them transform a few robots."

"The heat insulation effect must be good!"

Chapter 246 Double Ocean

Titan.

Kraken - the seaside of the Mare Sea.

The hatch of the Luanniao lying quietly on the shore opened slowly, and three robots with slightly strange shapes walked out of it.

In the cockpit of the starship, Zhao Zijie and Gao Yang looked at the hologram in front of them seriously.

Seeing the three robots walk into the methane sea step by step, Gao Yang let out a long sigh of relief: "Then we just need to wait, shall we?"

Zhao Zijie nodded lightly: "I guess it will take a few days for these robots to send back the test data."

In the holographic image, the scene in the methane sea is presented.

Because of the density of the methane sea, these robots can only "walk" along the seabed.

The sea floor is steep and spreads straight down into the depths.

The movement of the robot walking made the originally clear methane sea become turbid.

That is the fine sand formed under the "current action" of the methane sea.

A dim searchlight overhead illuminates the way forward.

In order to control the temperature, the power of each component in the robot body covered with a thick heat insulation layer has been castrated.

Therefore, the searchlight carried by the robot can only illuminate a small area in front of it, and most of the other areas are still dim.

Zhao Zijie turned his head to look at the test data on the side.

【Depth: 50 meters】

There was a bit of surprise in his eyes: "It's 50 meters deep so soon?"

Gao Yang shrugged: "Who knows?"

"After all, this is not the earth, and what happens is normal."

As soon as the voice fell, there was a violent shake on the monitoring screen.

A few minutes later, four large characters appeared on the hologram.

【Signal interruption】

Zhao Zijie suddenly turned his head and glared at Gao Yang beside him: "Gao Yang!!"

Gao Yang: "..."

"No, no, it's really not my fault!"

"How did I know this would happen?!"

Zhao Zijie sighed deeply, and withdrew his gaze from glaring at Gao Yang: "Yi, what's going on?"

"The sea water is too deep, and the signal transmission is hindered."

"This is impossible!" Zhao Zijie exclaimed in surprise.

"The signal transmission device on these robots is enough to transmit data on the bottom of the methane sea at a depth of 300 meters!"

Gao Yang's expression on the side also changed.

If there is a problem with signal transmission caused by the depth of the sea, then their understanding of the Kraken-Mare Sea will be refreshed again!

The holographic image began to play back various surveillance data a few minutes before the signal disappeared.

In the picture, the three robots are walking normally on the gravel-covered seabed.

Echo sounders show that the surface of the seabed is very flat, with few large rocks, and the depth is steadily increasing.

It seems that everything is normal.

But at the next moment, under the slow-motion camera, the flat seabed under the robot's feet suddenly broke, revealing a big hole!

In those short minutes, the echo sounder on the robot sent a lot of shocking data!

"Sea... Trench?"

Zhao Zijie stared blankly at the various data in front of him, and asked in a low voice.

"The statement is not accurate, Captain." One's response came later, "Its width is far greater than that of the trench. At least the echo sounder did not find a clear boundary."

Zhao Zijie took a deep breath.

"How many meters is the deepest part?"

One's response sounded: "According to the data from the echo sounder, the total depth exceeds 500 meters."

Hearing this data, Zhao Zijie felt a headache.

How come there are so many accidents!

While complaining in his heart, he cast a resentful look at his teammates.

Gao Yang scratched his head with a smirk, and said with embarrassment: "Zijie, do you want to report the situation to Professor Lu?"

"What do you say?!"

Zhao Zijie asked back angrily.

……

After ten minutes.

The two of them "obediently" sat on the chairs, facing the holographic image.

In the picture, Lu Yongchang frowned, sitting quietly behind the desk, as if thinking about something.

Zhao Zijie and Gao Yang were full of guilt, and frantically communicated their inner thoughts through their eyes.

Zhao Zijie: 'Damn it!How to do how to do?Professor Lu won't be angry, will he? '

Gao Yang: 'Isn't it? '

Zhao Zijie: 'Why not?Don't you know how much Professor Lu attaches importance to this matter?He has been asking about the progress of the robot transformation every day for the past few days! '

Gao Yang: 'Then what should we do? ! '

Zhao Zijie: "Don't ask me, ask your open mouth!" '

"Cough!" In the holographic image, Lu Yongchang coughed lightly.

Zhao Zijie and Gao Yang trembled slightly, and immediately stopped making eye contact.

"Why are you so nervous?" Lu Yongchang asked in a low voice with some doubts in his eyes.

"Teacher, professor." Zhao Zijie swallowed slightly, "I am responsible for this matter, I..."

Hearing this, Lu Yongchang laughed immediately.

"Come on, tell me, what are your responsibilities?"

While talking, he looked at Zhao Zijie with great interest: "It's because you didn't go into the sea to find the way for the robot?"

"Or, did you collapse the seabed?"

Zhao Zijie faltered for a long time, but couldn't come up with a word.

He couldn't say that he didn't control Gao Yang's crow's mouth, could he?

"Okay, I don't blame you."

Lu Yongchang smiled and waved his hands: "To be honest, I didn't expect this either."

"I have read all the data, and zero has also been simulated."

"This should be the unique geographical structure of Titan."

"According to the comprehensive analysis of various data, we found that Titan's ocean presents a double-layer structure."

"The upper layer is what we usually see, the Kraken-Mare Sea with a maximum depth of 300 meters."

"As for the lower layer, let's call it the inland sea for the time being. Due to insufficient data, it is impossible to describe it in detail. We can only confirm that its composition is more complex than that of the Kraken Mare Sea, and the water temperature is also slightly higher."

"Two oceans, naturally layered due to density issues, separated by a thin rocky structure."

"Nothing would happen under normal circumstances, but that area may be fragile, and our robot stepped on it."
