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

Apart from being more fertile, softer, and containing more oxygen and moisture, there is almost nothing remarkable about it!

As for some trace elements...

Except for a slight difference in proportion, it is also very similar to the soil on the earth.

The only discovery that can be called valuable is that the scientific research type I robot detected not low-intensity radiation in these soils.

However, no corresponding radioactive substances were found in the soil, such as radioactive minerals such as cobalt-60.

Mao Zhengzhi and others, who had no results in thinking, could only turn their attention to the rest of the samples.

Leaf samples.

Like the trunk, these thick leaves are quite resilient.

"Ok?"

Lu Yongchang frowned watching the movement of the scientific research robot in the holographic projection: "Something is wrong."

"What's wrong?" Mao Zhengzhi, who was highly concentrated, hurriedly turned his head and asked, "Professor, did you find any problems?"

"...Look at it." Lu Yongchang thought for a while, and called up a picture, "This is a sample picture just taken on the Lost Star."

After finishing speaking, he pointed to the holographic image in front of him: "This is the current one."

In the picture, the leaves and fungi in the laboratory are all drooping on the laboratory table, and the gloss of the surface is no longer the same.

"They..." Mao Zhengzhi's eyes twitched slightly, sensing something unusual, "Didn't it?"

"Isn't this too fast?!"

"Could it be a matter of atmospheric composition?"

"Probably not." Lu Yongchang shook his head without hesitation, "The environmental adaptation work of the biology laboratory has been completed, and the composition of the atmosphere inside is basically the same as that of the Lost Star."

He looked thoughtfully at the image of the lost star sent back by the high-altitude probe: "The only difference."

"maybe……"

"Radiation!"*2

Lu Yongchang and Mao Zhengzhi said in unison!

"Zero, prepare for the test!" Without any hesitation, Lu Yongchang directly issued an order, "Create some radiation in the laboratory!"

……

After a few minutes.

Several huge machines were transported into the biological laboratory.

In the first test, in order to prevent accidents, under the order of Lu Yongchang, Zero simulated the radiation near the surface of the Lost Star in terms of intensity and composition as much as possible.

Time passed slowly.

After being given sufficient water, the plant samples bathed in the radiation gradually regained their vitality on the Lost Star!

This undoubtedly verified the original conjecture of Lu Yongchang and others.

The plants on this planet feed on radiation!

"Take a sample and increase the radiation intensity they receive."

Lu Yongchang's eyes moved slightly, and he gave a new order again.

The scientific research robot perfectly executed Lu Yongchang's orders.

Radiation intensity gradually increased.

10%, 20%…

When the radiation intensity increased by 100%, the mutation appeared.

"professor!"

Mao Zhengzhi shouted excitedly: "They are repairing themselves!"

Lu Yongchang stared blankly at the projected picture, and murmured: "I saw it..."

In the picture, not only the leaves, but also the edge areas where the fungi and bark samples were cut are slowly growing at a speed visible to the naked eye!

The growth only lasted for a few minutes and quickly disappeared.

"Insufficient nutrition."

Mao Zhengzhi said in a low voice: "After all, it's a rootless weed. If the stored nutrients are used up, we can't repair it."

Lu Yongchang's eyes flickered.

"But even so, this characteristic is unimaginable!"

"If these barks are made into the radiation protection layer of the starship, and then given enough nutrients..."

"Even if the radiation protection layer is broken down, under the action of a large amount of radiation, they can even complete the repair work spontaneously!"

Lu Yongchang took a deep breath.

Among other things, based on this alone, this lost star must not be easily given up!

Chapter 596 Fungus?organ?

"professor."

Zero's electronic synthesizer sounded: "The radiation intensity of all samples has been tested."

"The data has been collated."

After the words fell, a holographic chart slowly appeared in front of Lu Yongchang and Mao Zhengzhi.

Looking at the data in the chart, the doubts on the faces of Lu Yongchang and Mao Zhengzhi gradually became more intense.

According to the detection of the scientific research robot, the radiation contained in those wide leaves is the weakest.

The bark comes next.

The trunk concentration is slightly higher.

This is all expected by Lu Yongchang and others, and they can even foresee that the radiation intensity at the roots of these giant trees may far exceed that of other areas.

But what they didn't expect was that the fungus living at the bottom of the giant tree had extremely high radiation!

Its strength is hundreds of times that of the leaf area, and dozens of times that of the trunk area!

"That's weird..."

Mao Zhengzhi frowned, and muttered to himself: "With the protection of the tree canopy, these fungi should not be exposed to radiation."

"Even if they can absorb the radiation in the trunk, their radiation intensity cannot exceed the trunk area..."

Lu Yongchang didn't speak, but just stretched out his hand and rested his chin to stare at the fungus with a huge cap and extremely bright colors in the holographic image.

After pondering for a long time, he spoke.

"Zero, sampling, comparing giant trees and fungi at the cellular level."

Mao Zhengzhi turned his head and looked at Lu Yongchang in surprise.

"professor?"

"You are..."

Lu Yongchang chuckled: "It's just a guess."

"In the pictures sent back by the detector at that time, these fungi were all growing in the root area of ​​​​the tree trunk."

"There was no trace of any fungal growth in the surface soil."

"What did you think of?"

Mao Zhengzhi's eyes widened a little, and he said with an incredulous look: "You suspect that these fungi... No, these fungus-like things are part of a giant tree?"

Looking at the radiation detection data, he muttered to himself: "So... these things may be the organs of the giant tree to store nutrients?"

"It's strange enough, how can a plant put its nutrient-storing organs in such a place..."

As he said that, Mao Zhengzhi smiled and shook his head: "Isn't it easy to be eaten by other creatures?"

There was no smile on Lu Yongchang's face.

He nodded solemnly: "It is most likely an organ of a giant tree."

"But I'm afraid...it won't be the organ of the giant tree to store nutrients."

"Huh?" Mao Zhengzhi looked at Lu Yongchang with some doubts, "What do you mean by that?"

"Look at its bright appearance, what do you think of?"

Lu Yongchang stared straight at the every move of the scientific research robot in the picture, and murmured in a low voice: "These giant trees... are probably a little different from what we imagined!"

Mao Zhengzhi's eyes were full of strong doubts at first, but after a few seconds, the doubts in his eyes dissipated instantly, leaving only spontaneous fear!

"Professor, do you mean..."

Mao Zhengzhi only felt a chill coming from behind, he swallowed hard, and said with a trembling voice: "These things that look like fungi are the predatory organs of giant trees?"

Plant predation, while rare, does exist.

Even on Earth, pitcher plants, Venus flytrap... these plants will prey on insects to provide nutrition for themselves.

Even, they have evolved unique predatory organs for this purpose.

Like the giant tree on the Lost Star.

But the volume of the two is not the same specification.

Mao Zhengzhi took a step back subconsciously, with horror written all over his face: "So... this planet is a cage full of countless baits?"

Lu Yongchang pouted at the holographic projection: "There is no result yet."

"Maybe my guesses are all wrong, or maybe..."

"Professor, the comparison work has been completed, and the similarity between the two is close to 99.9%."

The laboratory once again returned to dead silence.

……

"Ta...ta...ta..."

In the [Earth] office, Lu Yongchang sat behind his desk, subconsciously bent his knuckles, and tapped the desk in front of him lightly.

Above the desk is a holographic image of a planet.

"The Lost Star..."

He frowned and murmured in a low voice.

The rewards are great, but the risks are also high.

Not to mention those arthropods, just those giant trees that may be prone to predation may bring great losses to the landing operation.

Under normal circumstances, he should now focus on the black hole.

After completing a series of research, use the curvature engine to go to the habitable star system.

This is the ideal path of human civilization.

But thinking of that extremely grand war, and thinking of the strong anti-radiation ability of these giant trees, Lu Yongchang felt like being scratched by a cat.

"Professor, academician Zhu Ziwen is visiting."

The electronically synthesized sound pulled Lu Yongchang out of the endless entanglement.

"Zhu Ziwen?"

Lu Yongchang's eyes lit up, as if he had thought of something, he said excitedly, "Let him in!"

……

"Professor, sorry to bother you."

The door opened, and Zhu Ziwen's voice came in from the door.

Lu Yongchang raised his head and stared at Zhu Ziwen who was striding into the office.
