Walking briskly along the passage, Ye Fan examined the displays in the glass cabinet one by one, and finally understood the significance of the Bingshen National Inventory, the objects stored here are all kinds of rare and unique mineral items. The history of the construction of this treasury since the beginning of the last century, gradually collected unknown meteorites, metals, non-metallic substances found all over the country, with the passage of time, the progress of scientific research, some have been thoroughly analyzed, measured the content of the elements, some are still unknown, waiting for the future scientific explanation.

These stones are not of much use to ordinary people, but for the country, they are of great significance, and several of them have promoted the development of several important industries in China, directly led to technological innovation, and made certain fields at the forefront of the world.

Time has passed, even if this part of the stone has been thoroughly studied and is no longer unusual, but in order to show its merits, it still stays in its original position, leading the original number, silently confirming the changes of that period of history, and being a silent hero.

Except for this small number of exhibits that have been thoroughly studied, most of the remaining substances are still in the exploration stage, and roughly estimated, there are about 100 species.

Ye Fan didn't take this so-called treasury seriously before, but now, he gradually became more interested and showed a sudden look.

Yang Chongyan asked himself to come to this place to find materials for repairing the Dan furnace, it seemed that he had come to the right place, and after a few steps, Ye Fan saw a meteorite numbered 27. It was a palm-sized red stone, full of brilliance, shaped like a coral in the sea, full of branches and tentacles, and extremely delicate.

"It's really Zhang Guan Li Dai, where is this meteorite, this is the Seven Blood Spirit Fat!" Ye Fan shook his head and sighed as he opened the glass cover and directly put this piece of Seven Blood Spirit Fat into the storage bracelet.

In this plane of the earth, the Seven Blood Spirit Fat is also an extremely rare spiritual material, which can be taken directly, as long as it is in the Qi cultivation period, the monk can immediately jump to a level, but he cannot break through to the foundation building stage.

Usually, the Seven Blood Spirit Fat is used by the monks as the best choice to break through the ninth layer of Qi training, which is both safe and fast, and it is worth the money, and it will not be wasted.

The first harvest was to get this rare seven-blood spirit fat, Ye Fan was in a good mood and liked this place a little.

For him, this treasury is really a good place for Taobao!

Then in front of the No. 60 showcase, Ye Fan stopped again, this time, he could barely contain the ecstasy in his heart, if Yang Chongyan was here, he couldn't wait to pick up the old man and kiss him.

What is displayed in this glass cabinet is actually half a low-grade fairy spirit stone!

Originally, it was supposed to be a whole fairy spirit stone, but at this moment, it was cut off in half by some sharp weapon, only the size of a clove of garlic, but it still made his eyes extremely hot, and his face was full of fanaticism.

God knows how this half of the fairy spirit stone fell to the earth across the border, Ye Fan doesn't care so much, let's take it first!

Although he currently has no way to absorb the immortal aura in the fairy spirit stone, but after the tribulation period, when fighting against the heavenly tribulation, he can use the fairy spirit stone to set up a protective magic circle, and he can simply sit back and relax!

Surprise, what a surprise!

Obtaining the Seven Blood Spirit Fat had already made his trip worthwhile, but he didn't expect that even bigger surprises were yet to come.

However, if you think about it carefully, the power of a poor country, and the various strange stones and treasures collected by the people over hundreds of years, if you don't have one or two pieces to get your hands on, it is a bit shabby.

After putting away this half of the fairy spirit stone, Ye Fan's excited heart was still pounding. It's been a long time since he's experienced this feeling, and it's even more shocking than the surprise he tasted when he collected thousands of red dust and purple pearl cardamom!

He seemed to feel that in this world of scarce resources, it was not impossible to achieve positive results, as long as he searched diligently and often walked around places where no one had been, he might be able to find treasures from the garbage heap!

Cultivation of the way, to put it bluntly, is the process of finding various resources, some people in the process of bad luck, encountered some poor mountains and bad water, in the end can only look at the sky and sigh, some people are full of luck, once they encounter the opportunity against the sky, maybe they will soar in the day, cultivate the truth, in addition to looking at the talent and courage, the most important thing is to look at the face and look at the luck!

Perhaps it was good luck that had been overdrawn in advance, and until we reached the end of the treasury, we still hadn't found a single or two pieces of material to repair the Dan furnace. Compared to the two rare things of the Immortal Spirit Stone and the Seven Blood Spirit Fat, the materials used to repair the Dan Furnace are relatively common, but there is no collection here.

There was a burst of footsteps in the passage behind him, and Po Jun and Luo Liang arrived at this time.

"Hmm, what is this?" Stopping in front of the No. 204 glass cabinet, Ye Fan showed a puzzled look.

There was something he didn't recognize, a huge pitch-black stone, about a meter in diameter at its largest, with a smooth surface, like the egg of some kind of creature.

"It can't be a dinosaur fossil, right?" Ye Fan secretly looked at it with the eye of heaven, but he couldn't see through this substance.

"What is it? strange ......" his instinct told him that this olive-shaped stone must have a name, and that even he could not see why it was, that it must be a substance that he had never seen before.

There are many wonders in the world, even if they are real immortals, it is impossible to understand every world and every substance. The more unknown things are, the more they can arouse people's curiosity, Ye Fan thought about it, and decided to take this thing away first, and then study it slowly when he has time.

He opened the glass cover and prepared to place the massive stone in the storage ring.

This stone is too large, it is estimated that it will occupy at least one-tenth of the space, Ye Fan cautiously reached over, trying to pick it up, but it didn't move!

The weight of this thing is too scary, isn't it?

Ye Fan remembered that the density of some objects in the universe is amazingly large, so the mass is also very terrifying, for example, the Black Whale Galaxy, any grain of sand, converted into the weight of the earth, has reached tens of thousands of tons, this is not counting those more terrifying heavy materials, even immortals can't move! Of course, the black hole that people most often mention is also an alternative existence, a black hole the size of a peanut, the mass is about the same as the earth.

Looking at the nameplate, Ye Fan was stunned.

Bingshen 204, suspected neutron star material, weighing 1721.673 tons, was discovered in Shennongjia in the late Qing Dynasty......

More than 1,000 tons, no wonder you can't hold it by arm strength alone, which is equivalent to two large planes full of cargo!

I can only use the True Qi and remove it!

However, just as his hands condensed the True Qi, this boulder actually began to frantically absorb the True Qi in his body!

"Oops!" Ye Fan was shocked, he didn't expect this thing to be so evil, he wanted to get rid of it again at this moment, but he couldn't get rid of it, his hands were firmly sucked on his head, as if he was glued by universal glue!

Powerful suction, even if he doesn't run the dantian Zhenqi, he is also automatically sucking, and his hands are linked to the boulder into two one-way passages, and the Zhenqi is constantly rushing towards the weird stone at the same time!

A terrifying chill floated in his heart, at this rate, it wouldn't be long before his dantian would be pumped into a vacuum, and what would happen after the true qi was sucked up, Ye Fan couldn't predict it at all.

Maybe he has two lifetimes of fame and a lifetime of romance, and he is about to be buried on this stone of unknown origin!

He tried to move his position, but found that he couldn't move at all, and his feet were rooted. Because of the huge mass of this stone, and the fact that Zhen Qi was frantically absorbed into it, he was unable to hold this huge stone at all, and as Zhen Qi broke through the gates, he felt that he was extremely weak and drained of his strength!
