Age of Cataclysm: I can light up the technology tree

【in addition……】

Just when Lu Yongchang thought that this communication was completely over, [Nus] sent several new messages again.

[If possible, please bring some healthy Forsaken Giant Worm larvae. 】

[I can complete the collection and screening work for you. 】

Lu Yongchang raised his eyebrows.

[Nus]’s request far exceeded Lu Yongchang’s expectations.

Logically speaking, when civilization survives or dies, it should only care about the interests of its own race.

This abnormal phenomenon quickly aroused his curiosity.

[Give me a reason. 】

Nusi's response quickly appeared in front of him.

[The Forsaken Giant Insect is of extraordinary significance to our Nus civilization. 】

[In the past, when Kukukan darkened, they were the ones who allowed the Nus civilization to survive the difficulties. 】

[Therefore, when the brightness of Kukukan returns to normal, we will intentionally protect them and increase their racial density. 】

[Their excrement and corpses are also indispensable nutrients for us. 】

【so……】

Lu Yongchang chuckled, turned to Mao Zhengzhi beside him and asked, "Symbiotic species?"

Mao Zhengzhi nodded: "Judging from the description, it does belong to a symbiotic species."

"Professor, I suggest bringing a certain amount of giant worm larvae."

"Why?" Lu Yongchang looked at Mao Zhengzhi with interest, "As long as there is sufficient energy, the giant trees should not need to hunt. As for nutrients, we can also artificially prepare them."

"The space of the starship is limited. I don't think there is any need to waste energy on these low-level creatures."

"You can't say that!" Mao Zhengzhi looked serious: "Professor, if you want to create another Nus civilization, these giant insects are indispensable."

"Not only that, we also need to artificially create an environment where the radiation intensity changes."

"Otherwise, Nus civilization, which has no pressure to survive, may degrade its root system, which is unacceptable for human civilization!"

Lu Yongchang suddenly realized.

"You're saying that it was precisely because of the existence of these giant insects and the unpredictable shining star that the Nus civilization evolved such a flexible root system structure?"

"If that's the case..."

As he spoke, he raised his hand, preparing to re-edit a message.

Suddenly, a new message from [Nus] attracted his attention.

[In addition, according to my observations, the giant insects also gave birth to weak intelligence. 】

[Although it is not as good as me, it has broken away from the lowest level of life. 】

[It may become a useful weapon for you. 】

Lu Yongchang's hand suddenly paused, and then he entered a line of information with great determination.

[According to what you said. 】

…

The exchange has come to an end for now.

Lu Yongchang looked at the "sapling" that was growing vigorously in the biology laboratory and sighed with some emotion.

"A good civilization has become a subsidiary civilization of other civilizations."

After solving the major issue that had been bothering him for a long time, Mao Zhengzhi's face became much more relaxed. But after hearing Lu Yongchang's words, the originally relaxed look on his face became solemn again.

Become a subsidiary civilization.

A simple sentence, but the consequences are not simple.

First of all, after becoming a subordinate civilization, the Nus civilization lost its ownership of the Forgotten Star.

Lu Yongchang has already issued an order to send engineering ships and robots to the Forgotten Star to mine and manufacture some necessary supplies.

In this process, many lost giant trees will inevitably lose their lives.

But it has no standing to oppose this order from an autonomous civilization.

Secondly, in terms of war, Nus civilization does not need to worry about this due to its own characteristics.

But if it were an ordinary subsidiary civilization, once a war breaks out, they will inevitably be sent to the battlefield and serve as indispensable cannon fodder in the interstellar battlefield.

"In the final analysis, it's actually a matter of strength."

Mao Zhengzhi sighed lightly: "If one day, human civilization encounters a more advanced civilization, maybe..."

"This is not possible!"

Lu Yongchang interrupted him directly: "Human civilization has no choice but to surrender and become a subordinate civilization!"

"Even if we face the sweeper civilization and the pastoral civilization, we will only die on the road to charge!"

…

As the Forgotten Star incident came to an end, the interior of [Earth] gradually became deserted.

One academician after another entered hibernation.

Of course, Lu Yongchang is no exception.

According to the plan, Zero will implement the wake-up plan at the moment it receives abnormal data.

Inside the starship, the lights went out one by one.

Only the high-energy particles ejected from the nozzle of the antimatter engine proved that the fleet was not dead.

In the distance, in the Forsaken Star, the giant trees also started the "battle for the continuation of civilization."

From time to time there will be a slight vibration on the ground surface.

This is the movement that the roots of the underground tree are working hard to create at the core of the Italian network.

Making this core is obviously not an easy task.

The originally lush forest looked like it was decaying at this moment.

At the same time, a large number of abandoned giant insects were hunted by the tree roots, leaving only a part of the selected and excellent larvae, which were "imprisoned" by the tree roots near the core of the Italian network - that is, next to the 10,000-meter giant tree.

…

Time flies by, and in the blink of an eye, a hundred years have passed.

The black hole's huge accretion disk has dimmed a lot, and the intensity of the radiation it produces has also weakened a lot.

The original lush and green Lost Star has become a brown and green planet.

Decline has become the main theme of this planet.

The lack of energy, coupled with the laborious work of making the core of the new network, has caused the area of ​​the forest to shrink again and again.

The camera gradually zoomed in, passing through the dense atmosphere and coming to the surface of the Lost Star.

The vibration that lasted for a hundred years finally stopped.

At the north pole of the Lost Star, near the core area of ​​the old network, a huge sphere with a diameter of 100 meters, built by countless tree roots, quietly "lies" on the slightly concave ground.

This is the core of the new network made by the Nus civilization.

In order to ensure the growth of future generations, [Nus] stored all the memories of civilization in this new network core.

[Nus] carefully explored the status of the new network core with the help of the surrounding radiation.

This is something left for the future generations of civilization.

It must ensure that the core can work normally under any circumstances.

'What if human civilization regrets? ’

During this hundred years, this question flashed through its mind countless times.

But...

There is no answer to this question.

[Nus] "looked" at the shrunk disk in the sky and sighed in his heart.

This is the end of civilization, but also the beginning of a new civilization.
