Rhodium is a compound with strange properties, extremely complex composition, green translucent crystals, similar to crystals, but has very magical energy storage properties.

To put it simply, this compound can absorb huge amounts of heat, turn into a higher energy state, and steadily release this energy to the outside world at different speeds under different environmental parameters, thus returning to a lower energy level.

No one can really explain how this property, which is close to violating the second law of thermodynamics, works, and by far the closest thing to the theory is that the hedron has a structure beyond the spatial dimension of human knowledge.

Regardless, people quickly mastered the technology of using the properties of gallium to store and utilize energy, a technique known as the "gallium reaction cell".

Today, from the largest area control ship that humans can build, to the backup energy systems of rural homes, the entire alliance is full of devices that use this technology.

From the side of the mine, Han Jianfei knew that this planet, which was called the "Xia Zhi Satellite" by the Alliance, should be rich in this kind of rinium ore, but he never thought that there would be so much rampium on this crashed migrant ship.

Han Jianfei soon came to the chamber where the green crystals were found, and those irregularly shaped and charming crystals glowing with green fluorescence were safely placed in sealed boxes, and if it weren't for this excavation, it seemed that they would have been buried forever.

But now, they've been dug out of the dirt and neatly laid out in the chamber, six boxes in all.

Because they have been in an inert environment, they have only emitted a faint green fluorescence to their surroundings for more than 2,000 years.

It can be seen that before the crash, these galliums were in a high energy state, so that more than 2,000 years later, they are still emitting a steady and faint pale green light.

The closer he got to these rings, the more Han Jianfei could feel the trembling of the ice iron ring, although he didn't know why, he understood that some kind of device or machinery in the ice iron needed the high-density energy in these crystals.

He was driven by the resound of the iron ring, and his left hand, which seemed to tremble slightly, rested on the crystal in the chest.

He knew it was a bit risky, and if the jewel-like creature was actually activated to some kind of release condition, his actions would be tantamount to sitting on a fusion bomb and detonating it directly.

However, the second law of thermodynamics seems to have lost its relevance once again.

He could feel that it was a strange phenomenon that was difficult to achieve with any known theory or technology, because the box of crystals containing astonishing energy was fading at a speed visible to the naked eye until it became milky white and translucent.

The ice iron still vibrates, as if it was curling up in a dimension below Planck's scale.

But Han Jianfei could feel its thirst for energy, so he reached for another box of crystals with his left hand.

Genchiko, Modo, and the diggers of the two tribes on the side watched with horror as he brushed the open chests one by one with his left hand, and as if a miracle, the clusters of gems that glowed green in those chests turned milky white without exception.

In this way, when the energy stored in the rampium crystal in the fifth box was released, the Ice Iron Ring finally stopped trembling.

When Han Jianfei touched the ice iron as before, it also responded to his call as before.

This ring, which condensed the essence of the technology of the previous civilization, seems to be alive again.

Han Jianfei turned the ring slightly, he knew that as long as he wanted, it would allow him to make another ultra-long-distance leap of flesh and blood.

Only this time, he didn't dare to gamble his luck anymore.

"What is this?" Genchiko, stunned by the strange scene in front of her, finally came back to her senses.

She and Modo, the new chief of the Iron Seal Clan, were both people who had seen the power of technology in the outside world that was no less than a miracle, and realized faster than the people who knelt around them that it was just a technology they could not understand.

"It's the machines in the mine that dig and refine every day, and it's the cornerstone of our world's existence." Han Jianfei smiled, "As for why I can make them change color, seriously, I don't know." ”

He wasn't going to tell anyone about the iron, it was arguably his biggest secret, and no one knew what the ring meant to him except for Mavis and Dobby.

"Dig through!" Outside the cabin there was another cheer from the diggers, and soon someone came running up to tell the two leaders that they had finally dug through the chamber, which outsiders called the "Genetic Sample Bank".

When human beings take solid steps towards the entire starry sky, all the immigrants are the bravest group of the entire human race, they are the pioneers of human civilization in the sea of stars, and they bear the heavy responsibility of expanding the coverage of civilization.

As a result, the crops and frozen embryos in these "gene pools" in the migrant ships that departed in the era of the Great Migration allowed the immigrants to quickly obtain food and a relatively comfortable environment in the new world.

Therefore, in any migrant ship, the samples in the genetic sample bank are extremely important objects of protection.

Han Jianfei and the three of them came to the cabin, and under the protection of the sturdy armored hull, nearly a third of the area of the cabin was still intact, and nearly half of the cylindrical capsules containing seeds and embryos were still functional.

"I have to say," Han said, looking at these cylinders that had just been dug out of the dirt, and some of them were even as smooth as new, "our luck is really good." ”

On the way to the mine before, Han Jianfei once thought that more than two thousand years had passed, and there would be nothing of value in this ship.

This time, it was pure luck to bring people from the two ethnic groups to excavate, and I didn't have any hope, but I didn't expect that I would first dig out six boxes of extremely abundant Immium, and then really find a sealed and complete genetic sample bank.

After rummaging through more than a dozen capsules, he finally found two barrels of what he wanted.

Fast-growing corn, the favorite of all immigrants since the era of the Great Migration, has a growth cycle of only more than 200 hours, extremely high yield, fertile seeds, and rich in edible and engineering starch......

All in all, with the right temperature and light, this kind of thing is simply tailor-made for the tribes of the seamounts.

The first barrel was a little damaged on the outside, but when it was opened, the inert gas inside had leaked completely, the inner tank was broken, and most of the seeds had been carbonized.

Under the gaze of everyone, Han Jianfei opened the second barrel, and after a burst of pressure relief, dozens of glass jars filled with corn seeds appeared in front of everyone.

Gene banks are designed to be able to preserve seeds and samples for thousands of years, and this lucky capsule fulfills its mission perfectly.

"What is this?" Gentomoko asked the second same question today.

"This is the key to solving the problem of food for all." Han Jianfei cautiously picked up a jar of seeds, "Seriously, I didn't expect to really find this kind of thing." ”

Most of the Hedong and Ebony tribes live by fishing and hunting, and the Tieyin tribe wanders around and plunders, and for two thousand years, they have never seen seeds that can be planted on a large scale, nor have they thought about what can survive in the cold season covered with ice and snow.

After briefly explaining the role of these seeds, the leaders of the two tribes finally knew that this thing was not meant to be eaten directly, but another problem immediately came before them - how could these plants grow normally in the cold and frozen season?

After a while, the excavation team on the other side came with bad news, the ecological cabin of the migrant ship had been dug up, but the contents had been destroyed in the impact.

The only thing to be thankful for was that the excavation team found several intact rolls of plastic roll film inside.

These things are all designed to allow the settlers who land on the surface of the habitable planet to survive as quickly as possible after traveling long distances.

Although it is unknown why, the fleeing immigrants did not return to look for these items, but as if they were designed by someone, they became necessary to keep the two tribes through the cold season.

Indispensable.

Han Jianfei asked people to carry those plastic roll films, seeds and energy-depleted crystals, returned to the exit of the migrant ship, and rummaged through the various books on the ground for a long time, and finally found a basic agricultural guide.

He casually flipped through it and found something about the construction and maintenance of a fast greenhouse, and pointed it out to Genchiko and Moduo: "You two know these words, you learn them yourself, and then let people use the things they just moved out, find a sunny place to build these greenhouses, and build as many greenhouses as possible." ”

Then, he found the part about the planting of fast-growing corn: "And this part, according to this operation, after a long day and night at most, the corn will be ready to eat - remember to leave enough seeds for the next round of planting ......"

Han Jianfei suddenly paused, feeling a little nostalgic.

He felt that since his assassination on the Peace Monument Square in Fort Augustus, he had grown fond of feelings.

It's just a group of primitive civilization natives, when did he become like a housekeeper?

"You...... Want to go? Noticing the meaning of the repeated explanations in his words, Gentomoko asked.

"I want to go to the mine again," Han Jianfei subconsciously answered her question, but soon noticed the disappointment in the girl's tone, "It's okay, I won't leave so early, I'm just going to find something and confirm some things - I promised to take you out, and I will do it." ”

Yuan Zhizi nodded, when she didn't solve the food problem of the tribesmen in the cold season, she couldn't go anywhere, and she was relieved to hear Han Jianfei say that he would take her away.

"Heavy snow covers the mountain, how do you get there?" She was still a little uneasy, even the best hunter would not be able to climb the mountain in the snow.

"I ...... There is a way, but it can only go alone. Han Jianfei said, "You guys deal with these things first, continue to dig here, but don't move anything, I'll be back soon." ”

With that, he stepped out of the empty hatch and stepped into the snowstorm.

After avoiding the sight of all the people of the two tribes, he stopped in a flat clearing in the valley and slowly raised his left hand.

A black exoskeleton mobile armor nearly three meters tall appeared strangely in the open space in front of him.
