"Dwarf trees?!"

Wedel's statement, Hai Ge thought it was funny. The shortest tree here can also be taller than the tallest tree on the ground, what kind of concept is the word "dwarf" in his mouth?

However, Hai Ge politely replied, "Yes, just after that primeval forest became sparse. At the time, I thought that the rest of the journey was mainly to see the flowers and plants on the side of the road, but I didn't expect to see those strange trees again. No, it's not strange that they've lost their leaves, but I think it's weird that they have the last one on each branch. ”

"Not really," replied Wedel with a smile, "not only are those small trees taller than shrubs, but they are not among the species that exist on earth, and it is difficult to find a type similar to them, and their growth characteristics are understandable in your eyes. ”

"Oh?" These words perfectly confirmed Haige's speculation about the origin of the underground plant kingdom, and he was greatly excited and curious.

"Those trees, scientifically known as purple apricots, don't need to be hydroponic, they just need to receive strong sunlight every 12 hours, which is why I didn't let them grow with other big trees," Weedel said. The trees of the primeval forest are too tall and luxuriant, and it is easy to rob the purple apricot trees of the sunlight they need to grow. In addition, their leaves are not lost, but are picked by others. ”

"You're the picker, aren't you? After plucking those leaves, I boiled the juice with them. ”

"Not bad. It's hard to imagine how interesting those trees are. They are very united, and no matter how many years they live, as long as there is a green leaf left on the branches, the trunk will not die, as if the seeds of their reproduction come from the leaves. Therefore, on the U planet, we also call them the Tree of Hope, and their insistent persistence in life has always inspired us to bravely fight for a chance to survive no matter how harsh the environment is. ”

There was a mystery hidden in these words, and Hai Ge heard it. He immediately realized how fiercely the planet named U had struggled when it encountered a catastrophe, and the people united to resist the natural disaster, although they failed in the end, they were still glorious in defeat. As the nanobots successfully said, even if the planet perishes, the tenacious fighting spirit of the planet's humans will remain. Didn't the indomitable spirit of the U-star people be brought to Earth by Wedel?

Perhaps Wedel is the last remaining green leaf that symbolizes hope on the tree of hope revered by the U-star people. The U-star has the prefix "Wedel" in its name, and the last survivors of the planet have replaced their real names, "Bitoni", what a loyal way to commemorate it!

On the countertop next to the white porcelain cauldron, there were non-woven bags, which looked like they were filled with cement powder or lime powder, but from the opening of one bag, half of the bags were used, Hai Ge saw a silver-gray powder, and was wondering if it was metal powder, Wedel had reached out and grabbed a small handful, put it on a balance to measure the appropriate amount, and spilled it into the white pot.

At this moment, Hai Ge was sure that what he had boiled with purple apricot leaves was definitely not medicine, but he couldn't relate the liquid to the orbit, and finally asked, "Mr. Wedel, is it really the kind of material needed for the Earth Rescue Project?" ”

Before and after meeting himself, Haige's attitude took a hundred and eighty-degree turn, not only was he no longer as aggressive as a little tiger, but he was also polite, Wedel turned his head to look at him, but what he touched was still his simple and arrogant eyes.

In any case, trust between the two was established, and Wedell smiled with satisfaction, saying as a teacher would teach a student, "What I am working on is a metal material that can continuously absorb cosmic radiation waves and grow stronger and stronger on its own, just as plants absorb sunlight for photosynthesis. ”

"Ah......?"

Haige was stunned, thinking he had misheard, "You don't mean that if metal really comes out of this pot, it will be alive like flowers and trees?" But metals are inorganic, how can they be ......?"

Wedel laughed: "Don't limit yourself to the existing field of understanding, otherwise you will never be able to progress." You must know that the evolution of life on earth from a cyanobacteria to today, the evolutionary process has not stopped, which means that there are still many unknown areas for human beings to explore, such as my plant metal. Of course, we prefer to call it a supermetal. ”

"Plant metal!" Wedel officially named the material, and Haige couldn't tell whether he should be suspicious or convinced. But for the evolutionary theory proposed by the other party, he raised his hands in favor, and didn't he also say that there are actually many different ways to overcome a seemingly insurmountable difficulty?

Both of them have a point, maybe there is really no "impossible" in the universe, only the "unknown"? As long as the "unknown" becomes "known", the "impossible" will be disillusioned like a soap bubble. But if the "unknown" is always in the way, the "impossible" will be the only explanation for the difficulty and insurmountability. So "unknown" is just a synonym for "ignorance".

However, Weedel used a combination of plants and metals to develop a plant metal that can grow and breathe, and Haige is still surprised by this unheard of new material, and does not dare to express his attitude easily.

"Are you sure that your new metal materials will definitely survive in the cosmic environment?" Haige asked worriedly. In his opinion, if metals are real plants, they will have the same growth cycle as real plants. If the metal plant dies, won't the orbit also collapse?

Wedel looked at him again, his eyes meaningful, "That's a good question, I like children who are good at thinking." But I can't give you the answer now, maybe you can find the answer in the universe yourself in the future. ”

"Find out for yourself? Doesn't that mean testing the entire planet? Hai Ge thought depressedly, but didn't dare to say this question.

When metal powder is placed in a white porcelain cauldron, the blue-green liquid begins to change color. Wedel kept stirring with a long-handled wooden spoon, much like he was cooking rice cereal, because he was afraid that the rice paste would stick to the pan, so he had to stir it all the time.

"Ginkgo trees that grow on the earth, don't confuse them with purple apricot trees. The plant fibers contained in the leaves of the purple apricot tree are very coarse, and have excellent elasticity and toughness, and after being refined, they can be easily pulled. ”

Hai Ge listened carefully, just like in a fantasy, he regarded success as a teacher. He had never been to a real school, but he was fascinated by school life, and now he felt a great honor to be guided by such an unfathomable master, who was still from an alien planet.
