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

"what's the situation?"

"Why did all these jellyfish go to the searchlight?"

Looking at the first-person view of the "Fishing Team", Zhao Zijie raised a question.

Lu Yongchang, who was on Mars, naturally also saw this strange scene.

"Phototaxis?"

He frowned and said.

"Forget it, don't worry about it."

"Zero, hurry up, grab one and come in."

Zero, who received the order, controlled the robot to quickly walk towards the jellyfish on the side.

Something even more surprising happened.

Those lagging jellyfish seemed to have sensed the existence of the robots, and quickly turned around and rushed towards the two robots!

"zero!"

Seeing this scene, Lu Yongchang couldn't help but suffocate, and shouted in a low voice: "The speed is fast, they may have wisdom!"

The robot's movement speeded up a bit in an instant, and it squatted down and grabbed the jellyfish beside it.

Fishing failed.

"Zero, what's the situation?"

Lu Yongchang frowned and asked in a deep voice.

"Professor, it's slime." Zero quickly responded, "The surface of these creatures is very slippery."

As soon as the words fell, the jellyfish, which escaped capture by relying on the mucus on its body surface, "jumped up" and hung half of its body on the first robot!

"zero……"

Before Lv Yongchang gave the second order, one after another the light yellow jellyfish resorted to their unique skills and rushed towards the robot.

"Alarm, low power."

The holographic projection interface in front of him instantly turned red, and Zero's warning sound followed.

Seeing that the first robot was about to collapse under the siege of the "jellyfish army", Ling did not wait for Lu Yongchang's order, and directly manipulated the other robot to squat down and drag the fallen robot into the starship.

The next moment, the hatch closed abruptly, blocking the movement of those jellyfish.

The whole process probably took less than a second.

Lu Yongchang let out a long sigh of relief, and calmed down his violently beating heart.

"Nice job, Zero."

……

In order to maintain the biological activity of these jellyfish, the area leading to the hatch is completely closed and consistent with the surface environment of Titan.

"I take back my previous judgment."

Lu Yongchang stared at the surveillance screen and said softly: "These indigenous creatures should not have wisdom."

In the picture, a few jellyfish that were dragged in together are attached to the surface of the robot "sweetly" and have no idea where they have come.

"Professor, so what is attracting them?" Gao Yang asked in a low voice.

There are no searchlights on these two robots.

This rules out the previous speculation about phototaxis.

Lu Yongchang raised his eyebrows: "I probably guessed it."

"However, a small experiment must be done first."

……

inside the laboratory.

A pale yellow jellyfish lies quietly on the icy ground.

Perhaps because of being away from the methane sea for a long time, it seems a little "sluggish".

But when an instrument is activated, its spirits are lifted!

The jellyfish "swiftly" crawled towards the opened instrument.

The position of the instrument changes slowly, and the trajectory of the jellyfish also changes accordingly.

"It's almost certain."

Lu Yongchang clapped his hands, and wrote a line of words on the paper with a pen: "Similar to phototaxis, but they are thermotaxis."

"That instrument is nothing more than a warming device."

"Compared with the ambient temperature, it's about ten degrees Celsius higher."

"Zero, the next experiment, start adjusting the temperature of the heater."

After dozens of experiments.

Lu Yongchang looked at the jellyfish in the surveillance screen in surprise.

"incredible."

"It's so sensitive to temperature!"

According to the experimental results, these jellyfish can keenly detect objects tens of meters away that exceed the environment by 0.1 degrees Celsius.

This also explains the phenomenon that they are adsorbed on the surface of the starship.

In the eyes of these jellyfish, the starship and extraction device in working condition are as conspicuous as a stove in a world of ice and snow!

The idea of ​​solving this problem also came to Lu Yongchang's mind.

All it takes is something warmer to get their attention.

After telling Zhao Zijie the solution, Lu Yongchang immersed himself in the study of alien creatures again.

……

The hurricane slowly receded.

The tide is also gradually receding.

On the slightly damp beach, only the ostrich starship and the extraction device were left covered with jellyfish.

"Zijie, are you sure it's okay for us to do this?"

Gao Yang, who was sitting in the driver's seat, looked at Zhao Zijie anxiously, and asked again and again.

Zhao Zijie shrugged: "Then do you have any other methods?"

Gao Yang's face collapsed.

Well, he admits, it seems to be the only way for the Luan starship without a weapon system.

With helplessness in Zhao Zijie's eyes, he pressed a button on the console.

A thin faint blue flame appeared at the bottom of the ostrich.

Hall thrusters activated.

Although the power was small, the plasma wake of hundreds of millions of degrees still dried up the ground in an instant, attracting the attention of all jellyfish by the way.

After feeling this unprecedented "warmth", these jellyfish immediately released the suction cups at the bottom, and moved towards the ground and the nozzle of the Hall thruster without hesitation.

The result can be imagined.

The high ambient temperature vaporized the liquid methane inside the jellyfish.

The size of each jellyfish swelled instantly, and then exploded like a balloon, leaving only viscous liquid all over the ground.

Chapter 244 Lu Yongchang: You haven't done anything yet, have you?

After more than an hour, Zhao Zijie turned off the Hall thruster with satisfaction.

"Huh!"

Gao Yang walked quickly to the porthole and looked down.

"The effect is outstanding!"

A smile appeared on Zhao Zijie's face: "No, high temperature is the natural enemy of these creatures!"

"According to the test results, most of these organisms are liquid methane."

"It's like water in living things on Earth."

"Under the current atmospheric pressure, the temperature at which methane liquefies is around -160 degrees Celsius."

"In other words, as long as the ambient temperature rises above 20 degrees Celsius, these organisms will explode and die."

"But even so, they still can't control their nature."

As soon as the words fell, a holographic image suddenly appeared next to the captain's pilot's seat.

"Captain Zhao Zijie, are the creatures outside still alive?"

Lu Yongchang's urgent voice came from the speaker.

……

Oh shit, it's over.

Zhao Zijie and Gao Yang looked at each other awkwardly.

"Captain Zhao Zijie? Can you hear me?" Lu Yongchang's urgent voice continued, "You probably haven't done anything yet, have you?"

Zhao Zijie's expression turned bitter.

Don't talk about doing it, they are all ready to clean up the battlefield.

"Cough cough!"

Zhao Zijie coughed lightly, the corner of his mouth twitched and said, "Professor, your communication is a little late."

"Those jellyfish have..."

In the holographic screen, Lu Yongchang was already frozen in place.

"All, all dead?"

"Yes." Zhao Zijie became more and more embarrassed, "How about I go to the sea to catch you some more?"

Lu Yongchang: "..."

"Forget it." He waved his hand helplessly and said, "Wait for the next high tide."

"Just right, there are still some test results that haven't come out yet."

Gao Yang's eyes showed some curiosity: "Professor, did you find anything?"

"Are these jellyfish useful to us?"

Lu Yongchang didn't hide it, nodded and said directly: "Not bad."

"The bodies of these jellyfish are mostly composed of liquid methane. You should be aware of this."

Seeing the two nodding, Lu Yongchang stretched out his hand to pick up the water glass on the side and took a sip of water to soothe his dry throat.

"In the process of life activities, a large number of chemical reactions will occur."

"Liquid water is an excellent solvent that allows a wide range of chemicals to fully react."

"It is also true that in the search for extraterrestrial life, we have always focused on the search for liquid water."

"But these jellyfish show us another way."

"Their body composition, except for liquid methane, is mostly lipid compounds."

"These lipids dissolve relatively easily in liquid methane, which provides a good basis for the reactions of life."

Gao Yang muttered to himself: "So, I said they look like fat, are I really right?"

Lu Yongchang was stunned.

"Although it is somewhat inaccurate, it can be understood in this way."
