There was a sudden numbness in the brain, and Han Sen only felt that his brain seemed to wake up instantly, and the pituitary gland seemed to secrete a cool and cool liquid, making the brain clear like an epiphany. Pen, fun, and www.biquge.info

"Brain lenses are a good thing, but unfortunately the effect will slowly fade, and in the end it can only play a role in promoting brain development. Han Sen pocketed the rest of the brain crystals and looked towards a triangular exit in the center of the room.

The interior of the entire room is spherical, except for the crack that has exploded above, and there is only a triangular passage in the center of the bottom.

Han Sen walked to the side of the passage and looked down, only to see that the passage extended down for about two meters, and it was connected to another spherical room.

"Yanran, do you know what these spherical rooms are for?" Han Sen knew too little about the Jing Clan, so he had to look at Ji Yanran.

Ji Yanran shook her head slightly: "Among the Jing clan materials I have read, there is no mention of similar places. However, there are many things that the crystal civilization has not cracked, which is not surprising. ”

"Shall we go down and have a look, maybe we can find the brain crystals. Han Sen thought for a moment and said.

Li Mingtang and the prince entered the core area, but the guard crystal nucleus also chased in, Han Sen didn't know what was going on inside, in case they followed in and met the guard crystal nucleus, it would be really troublesome.

"I don't know if it's going to be too risky. Ji Yanran hesitated.

"Don't risk it. Han Sen directly summoned Xue Ji and asked Xue Ji to go down from the triangular passage to see what was going on inside.

Soon Han Sen was sure that there was an empty room underneath, and Xue Ji found a triangular passage to the rest of the place.

Han Sen hesitated, but still summoned the Worm Knight, and asked him to hide in the ears of the huge god statue again, monitoring the entrance of Li Mingtang and their entrance, while he and Ji Yanran went down the triangular passage and entered another circular room.

Sure enough, as Yukihime said, it was an empty room, and a triangular passage of the same size opened on one side of the room, which ran horizontally through to another spherical room.

Han Sen asked Xue Ji to climb through the passage, and after making sure that there was no danger inside, he and Ji Yanran climbed over one after another.

There was a spherical room connected to a spherical room, and there was no room in the room, Han Sen and Ji Yanran walked through more than a dozen spherical rooms, and finally arrived in a normal room.

On the walls on both sides of this room are black crystal cabinets like storage boxes, consisting of small black crystal cabinets, at least hundreds, and I don't know what is inside.

"It's ...... Crystal Nucleus Library......" Ji Yanran saw those black crystal cabinets, and her face showed surprise.

"You said this is the crystal nucleus library, is it the place where those simulated crystal nuclei, parasitic crystal nuclei, and guarding crystal nuclei are stored?" Han Sen was ecstatic in his heart, he didn't expect to come here by mistake.

"These black crystal cabinets are very similar to the cabinets used to store crystal nuclei in the crystal nucleus library that were discovered before, but this room is a little different from the crystal nucleus library found before, and this room is connected to those spherical rooms, I don't know what the use is, I don't know if it's really a crystal nucleus library. Ji Yanran was a little unsure.

"Just open one and take a look. Han Sen asked Ji Yanran to retreat into the spherical room first, while he watched Xue Ji open a square black crystal cabinet.

There was no accident, the black crystal cabinet was empty, and there was nothing to store inside.

Ji Yanran came down to look at the internal structure of the cabinet, and immediately said with certainty: "That's right, this is the cabinet where the crystal nucleus is stored, it should be a crystal nucleus library here, but the scale seems to be a little too small, like this crystal clan king ruins, the crystal nucleus library should be very large, the black crystal cabinet in this room can't even compare to the crystal nucleus library of some small crystal clan ruins, it doesn't look like the royal family's handiwork." ”

"It's good that it's the crystal nucleus vault, maybe this is the small vault of the king of the crystal clan. Han Sen was excited, and ordered Xue Ji to continue to open the other cabinets.

Dozens of cabinets were opened in a row, and all of them were empty, which made Han Sen slightly disappointed.

However, Han Sen was unwilling to return empty-handed, and ordered Xue Ji to open all the cabinets one by one, and when he reached the eightieth cabinet, he suddenly found that there was a glimmer of light flickering in that cabinet.

Han Sen was overjoyed, and hurriedly walked to the side of the cabinet to take a look, only to find that it was a golden gem, only the size of a fingernail, oval-shaped, with countless facets, and it looked like a shining golden diamond.

"Is this thing a crystal nucleus?" Han Sen didn't dare to move, looked at Ji Yanran and asked.

Ji Yanran nodded and said: "This is the crystal nucleus that has not been activated, looking at the appearance of this crystal nucleus, after it is activated, it should be the kind of Rubik's Cube guard you have seen." ”

"It won't start on its own, will it?" Han Sen was startled.

Ji Yanran shook his head and smiled: "Definitely not, the crystal nuclei in the crystal nucleus library are all in a blank and dormant state, and they will not be activated without the instructions of the crystal clan, and now even if you want to find a living crystal clan to come out and activate these crystal nuclei, it is impossible." This kind of Rubik's Cube Guardian Crystal Accounting is a more common kind of crystal nucleus, but generally those relics are second- and third-order Rubik's Cube guards, and among the larger crystal relics, the more common ones are the fourth, fifth and sixth orders, and it is more difficult to see no matter how high it is, like the kind of twelveth-order Rubik's Cube guards you see, it is very rare, and has a high collection and research value. ”

When Han Sen heard Ji Yanran say this, he was overjoyed, and directly grabbed the golden crystal nucleus and stuffed it into his pocket, and said with a smile: "Then I'll put it away first." ”

Ji Yanran knew Han Sen's thoughts, but she just glanced at Han Sen and didn't say anything.

With the harvest of the Rubik's Cube Guarding the Crystal Nucleus, Han Sen was even more motivated, and asked Xue Ji to open the remaining cabinets one by one, and after a while, he found another crystal nucleus.

This was a white crystal nucleus, and Han Sen looked at Ji Yanran suspiciously.

"This is the memory crystal nucleus.,The information left by the crystal family is recorded inside.,If the mental power is strong enough,You can directly perceive the content in the memory crystal nucleus.,But it's basically difficult for humans to do this level now.,Relying on instruments can only get some information fragments in the memory crystal nucleus.。 Since this memory crystal nucleus is left by the Crystal Royal Family, it may contain important information about the Crystal Family, and if some of it can be deciphered, it may be able to make human science and technology develop by leaps and bounds. Ji Yanran explained.

"Then I'll keep it first. Han Sen was also polite, and put away this memory crystal nucleus.

"Did you hear anything?" Han Sen suddenly pricked up his ears and looked at Ji Yanran with a puzzled expression.

Ji Yanran shook her head slightly: "What voice did you hear?"

Han Sen was about to say something, but he heard a clanging sound falling into his ears, only to see pink crystals the size of duck eggs rolling down from the triangular passage they came down from, and more than a hundred had already fallen in a moment.

"Parasitic crystal nucleus!" Han Sen and Ji Yanran were shocked almost at the same time.
