The reason for the existence of biodiversity is that organisms are constantly adapting themselves to changes in their environment.

In order to avoid being eliminated by nature, the potential in the genes of organisms will be stimulated. So whether it's in the extreme cold or in the hot crater covered with sulfur, there are creatures that survive.

In a nuclear radiation leak in the 21st century, animals were left behind, even though humans were evacuated from the contaminated area. For decades, some animals, despite the effects of intense radiation, did not distort and die as expected, but multiplied in large numbers, as if the radiation had not affected them.

Therefore, Qiao Hua speculated that there must be certain organisms on Earth that were able to maintain the normal functioning of the body under the influence of radiation. And what he has to do is find these creatures and get their genetic fragments.

No problem.

With a rough idea in mind, the dwarf tyrannosaurus can't wait to implement it. The parts of the unlucky machine assistant have not yet completely cooled, and they have to be dragged up by Qiao Hua to do something else.

If it is a big project to just complete the refining of dozens of tons of ore, then what Qiao Hua asked Tie Dan to do next can be regarded as a project against the sky under such a simple situation.

According to the maniac's idea, he needed to build an experimental field the size of at least ten football fields, with a protective shield to shield it from radiation on the outside and partitions on the inside, making it look like a prison.

In principle, the whole site should have a complete set of ecosystems, which are self-produced and sold, and will not have any impact on the outside world.

"Crackle-"

When Qiao Hua finished talking to Tie Dan about his idea, he obviously heard such a voice coming from this guy's body.

"Neither theory nor practice is feasible." White mist whirred from the Iron Egg's head, "It will take about a year to synthesize enough material to make the outer radiation barrier. The manufacturing process of a complete ecosystem is extremely complex and requires a lot of space. ”

"So can we create an ecosystem that can last for three years?"

"I can't."

"What about the two years? Two years of work is not ......"

"The temperature is too hot, and the body goes into a dormant state."

Qiao Hua's question hadn't been finished yet, and the light in Tie Dan's eyes had dimmed.

Since the beating came down from the assembly line, the iron egg has never been used with such high intensity. You must know that the results of its sleepless work in the past few days can almost be comparable to the output of a small factory.

Although Qiao Hua felt that the aftermath was not over. But it took a while for the iron egg to dissipate heat and recharge, so I had to fall asleep first.

In the haze, Qiao Hua felt that the night was extremely cold.

……

"-Sneezing!"

The dwarf tyrannosaurus felt a little itchy in its nose and couldn't help but sneeze firmly.

The pit that slept on his nose was immediately sprayed out by the cyclone, and it rolled a few times before it stopped, and shook its dazed head and climbed up the tree.

Qiao Hua opened his eyes and looked to the side, and saw that the bean paste was drinking water next to a small puddle not far away, and the iron egg had also returned to its normal state after a night's rest.

Compared to yesterday. Today's temperature seems to have dropped a lot, and the light and shadow on the ground are dim.

Qiao Hua turned his head as if he suddenly felt something.

A large black shadow was separated between the Earth and the Sun, blocking the light of the smaller half of the Sun, which at first glance looked like the beginning of a solar eclipse.

But Qiao Hua knew that it was not a solar eclipse, because the afterimage of the moon was still hanging on the western canopy. There is no doubt that this huge black shadow is the celestial body that has been inexplicably pulled into the orbit of the solar system.

Compared with last time, Qiao Hua obviously felt that this thing was a lot bigger. Of course, this is not really a growth in volume. Rather, it is a visual error caused by the proximity to the Earth.

As the altitude angle of the sun increases, the outline of the black shadow is gradually revealed. Qiao Hua could see the potholes on its gray-yellow surface, and the irregular rings of mountains.

For the little life on Earth, such a scene really seems a little scary. Although Ida said that according to the current trajectory, it would be at least ten years before this celestial body collided with the earth, but Qiao Hua looked up at this scene, but he always felt a chill down his spine. It seems like the end will come at any moment.

He forced himself not to look up at the sky - it wasn't time to worry about it, he had more important things to do.

Qiao Hua turned his head.

The machine assistant also glanced at Qiao Hua's side, and when he saw this, he suddenly converted the two mechanical long legs into wheels and ran away with a "creak".

“……”

The dwarf tyrannosaurus reluctantly scratched its belly with its claws. In fact, what he wanted to talk to Tie Dan was that after a night of thinking. He's found an alternative way to stop having to do that much work.

Half an hour later, Qiao Hua and Tie Dan arrived on a small island in the subtropics.

This place was found by Qiao Hua through the global search system, and the entire island is about a hundred square kilometers, which is beyond the scale of Qiao Hua's needs. The main reason why this island was chosen as the experimental area is that it is extremely rich in species - they will all become Qiao Hua's experimental subjects.

Subsequently, the dwarf tyrannosaurus found a small island in the temperate zone and a small island in the subarctic zone as an experimental base, so that the species available for experimentation were more abundant. But he still didn't seem satisfied, and added many species of creatures from the land to the three islands that were not available on them.

Finally, the most important step remains.

In the early Eocene, three small nuclear bombs were detonated on three unnamed islands on Earth.

When Qiao Hua asked Tie Dan to do this, he also used some tricks: he did not let the high heat released by the nuclear bomb explosion act on these creatures, but only exposed them to the high radiation produced after the explosion.

These radiation-affected organisms will be monitored for a long time to come, with the aim of identifying species that are not affected by radiation.

After doing all this, Qiao Hua felt physically and mentally exhausted, but he was sure that all the effort he put in was worth it.

From a humanitarian point of view, the actions of this dwarf tyrannosaurus seem to be too frenzied, and even more brutal than Adolf Hitler, who lived in prehistory.

But if these boring human moral standards are abandoned, Qiao Hua thinks that he is making a great attempt at the moment, and if he can succeed, it will be an important milestone in the history of life on earth. What is such a sacrifice compared to what could be achieved? (To be continued.) )
