I saw that the mysterious spar, which was originally three meters long, two meters wide, and one meter thick, had shrunk a lot at this time, and only about half of it was left.

"What's wrong with the hedron?" Ming Ying was stunned.

"Let's take a look at the mysterious space!" Ming Ying immediately called Jiang Yun, Zuo Fang, Liu Jun, and Zhang Qiang, and after explaining, he put the mysterious spar into the mysterious space again with a wave of his big hand, and then entered the mysterious space himself.

As soon as he entered the mysterious space, Ming Ying was stunned again.

At this time, the mysterious space was roaring everywhere, the sky was full of dark clouds, and dark cracks could be faintly seen, like black snakes dancing wildly.

Moreover, the mysterious space has become significantly larger!

Ming Ying clearly remembered that he had only divided a space of 100 meters square to store supplies.

And at this moment, the mysterious space is more than a hundred meters square, and the length of this side has reached more than a kilometer.

"Is it the reason for the mysterious spar?" At a glance, Ming Ying saw only half of the mysterious spar remaining.

At this time, the mysterious hedron was silently suspended in the air, exuding a misty luster. As soon as these brilliances escaped from the surface of the mysterious spar, they quickly disappeared, as if they had been absorbed by the mysterious space.

"I see!" Mingying's eyes brightened instantly, and his breathing became short.

Mystic Space is able to absorb Mystic Crystals and then expand!

At this moment, Ming Ying thought too much.

For example, Mingyun City will be expanded to bless more people. For example, using the ability of spatial segmentation, a giant city will also be built in Huadu, and even 50 bases in Huaguo will be built into Mingyun City in the future.

"Great!" Ming Ying was so excited that his whole body trembled, and then he calmed down again, and said secretly: "This mysterious spar can promote the evolution of the mysterious space, so it is called the 'Space Stone'." Also, I'm going to take a small piece out and give it to an expert to study. ”

Now that all the experts in Huaguo are gathered in Mingyun City, the research force is unprecedentedly strong, and maybe something good can be studied.

Ming Ying hurriedly divided a ten-centimeter-square piece from the remaining spatial stone, and then left the mysterious space in a hurry.

Immediately, on the sofa in the fortress room, Ming Ying jumped up, startling Jiang Yun, Zuo Fang, Liu Jun and others.

"Mingying, what are you?" Everyone was puzzled.

"If you have made a big discovery, let's go, go to the experts." Ming Ying grabbed the stone of space, pushed the door out directly, didn't even have time to wait for the elevator, jumped directly down the stairs, and went downstairs in two jumps, and came to the fourth underground floor of the apocalyptic fortress.

The Apocalyptic Fortress has five underground floors, all of which are now temporarily vacated for experts to study.

The first layer is an expert in the field of materials, and now Feder alloy has been successfully developed, but at present, human beings still only know what it is, and do not know why it is.

Therefore, experts are still frantically researching, in order to find some regularities in the process of Feder alloy, so as to make other materials.

The second layer is an expert in the field of Void Ion Engines, this technology has the best human foundation, and has already built some low-thrust ion engines, but has not been able to build high-thrust Void Ion Engines.

And what Ming Ying brought back was the technology of building a high-power Void Ion Engine, so the experts in this area are now hungry and thirsty, and they stay in the second layer when they eat and sleep.

The third layer is biotechnology experts, who are said to have conquered the treatment of two types of cancer through genetic technology. Chu Feng, a weapons expert found by Ming Ying from Linhu City, is now also in this team, participating in research as a "semi-layman".

The fourth and fifth layers are experts in the field of plasma batteries and energy fields, because these two fields are much beyond the existing technical level of human beings, and the research and development progress of these two expert teams is very slow compared with the other three expert teams.

As soon as Ming Ying walked to the fourth floor, he suddenly saw an old man with gray hair looking down at a document, still pacing back and forth, sighing while reading, looking very anxious.

"Teacher, you don't have to be in such a hurry, Mr. Liu's side is already working superconducting materials, once the type 6 superconducting material is researched, we can conduct experiments." A middle-aged man in white comforted.

"Pony, now Lao Lu's Void Ion Engine has made a big breakthrough, once it is successfully developed, it will inevitably require high-power electricity, if our plasma battery technology can't keep up, I'm worried that the entire project will be delayed." The white-haired old man looked very sad.

Ming Ying saw this scene in his eyes, and his heart was also in awe, moved by the professionalism of these researchers.

"The experts forget to sleep and eat every day, and even don't rest at all, this is the backbone of my country." Ming Ying's heart was moved, and he didn't bother the two experts, but walked down the fifth floor lightly.

On the fifth floor, a group of experts were the same, all gathered around a large table, holding pencils and writing on white paper, writing down lines of calculation formulas that Ming Ying couldn't read.

In the corner of the fifth floor, more than a dozen rows of wooden cabinets have been added, which are already filled with stacks of manuscript paper, densely packed with numbers and letters.

These are all calculated by the experts who have forgotten to sleep and eat in the past few days.

Ming Ying watched the experts work hard to write, and he couldn't bear to be disturbed, so he stood quietly and waited for more than half an hour, when one of the experts suddenly sighed: "Dean, I have calculated more than a hundred times, but I still think that this model always has shortcomings, but I am afraid that it will not be able to build a stable energy field." ”

After the expert finished speaking, he was about to pick up the water cup beside him to drink, when he looked up and happened to see Ming Ying, he suddenly exclaimed: "Long Shuai, why are you here." ”

At this time, other experts also raised their heads one after another, and they all stood up immediately after seeing Ming Ying.

Seeing this, Ming Ying said, "Experts, I'm sorry. ”

Long Shuai laughed. The expert at the head is the current president of the Huaguo Institute of High Energy Physics, a middle-aged man named "Su Zhe" in his forties, dressed in a white research suit, with bright eyes.

"I'm here this time because I brought something and I want to ask the experts." Ming Ying took out the Space Stone.

"I found it by accident, and I feel that this spar seems to contain a strange energy, and I want to ask the experts to help me take a look." Ming Ying explained the intention.

Several experts' faces suddenly changed, and they exclaimed: "There is energy in the stone? Radioactivity? ”

"City Lord, you hurry up and put it down, let's test it. If it is radioactive, it is harmful to the human body. Dean Su Zhe hurriedly said.

Ming Ying shook his head and said, "I can't feel the radioactive energy from this stone. ”

"Oh? That's weird. Several academicians and experts are bright-eyed.

The absence of radioactivity means that the energy is very stable, but things like stones should not have the property of storing energy stably.

It's weird.

Suddenly, a young researcher exclaimed, "Dean, isn't this a stable energy field?" ”
