There was a sudden numbness in his brain, and Han Sen felt as if his brain suddenly woke up. The pituitary gland seemed to secrete a refreshing liquid, making his brain as clear as an epiphany.
"Brain crystals are really good things. Unfortunately, the effect will gradually fade away. In the end, they can only promote brain development." Han Sen put the remaining brain crystals into his pocket and looked towards a triangular exit in the center of the room.
.
The interior space of the entire room is spherical. Apart from the cracks that exploded above, there is only a triangular channel in the center below.
Han Sen walked to the passage and looked down. He saw that the passage extended downward for about two meters and was connected to another spherical room.
"Yanran, do you know what these spherical rooms are used for?" Han Sen knew too little about the Crystal Clan, so he had to look at Ji Yanran.
Ji Yanran shook her head slightly: "In the information about the Crystal Clan that I have read, there is no mention of anything similar. However, there are many things that the Crystal Clan civilization has not cracked, so it is not surprising."
"Should we go down and take a look, maybe we can find brain crystals." Han Sen thought for a while and said.
Li Mingtang and Wang Hou entered the core area, but the guard crystal core also chased them in. Han Sen didn't know what was going on inside. If they followed in and encountered the guard crystal core, it would be really troublesome.
"I wonder if it would be too risky." Ji Yanran hesitated.
"No risk." Han Sen directly summoned Xue Ji and asked her to go down the triangular passage to see what was going on inside.
Soon Han Sen determined that there was an empty room below, and Xue Ji discovered a triangular passage leading to other places.
Han Sen hesitated for a moment, then summoned the insect armor knight and asked him to hide in the ear of the huge statue again, monitoring the entrance where Li Mingtang and the others entered. He and Ji Yanran went down the triangular passage and entered.
Another round room.
Sure enough, just as Xue Ji said, this was an empty room. A triangular passage of the same size was opened on one side of the room, leading horizontally to another spherical room.
Han Sen asked Xue Ji to crawl through the passage. After making sure there was no danger inside, he and Ji Yanran crawled over one after the other.
There was a spherical room connected to another spherical room, and both rooms were empty. Han Sen and Ji Yanran passed through more than a dozen spherical rooms and finally arrived at a normal room.
The walls on both sides of this room are black crystal cabinets that look like storage boxes. They are composed of small black crystal cabinets. There are at least hundreds of them, and it is unknown what is contained in them.
"This is...the crystal core library..." Ji Yanran saw the black crystal cabinets with a look of surprise on her face.
"You said this is the core library? Is it a place where those simulated cores, parasitic cores, and guard cores are stored?" Han Sen was so ecstatic that he didn't expect to stumble here by accident.
"These black crystal cabinets are very similar to the cabinets used to store crystal nuclei in the previously discovered crystal nuclei library, but this room is a little different from the previously discovered crystal nuclei library, and this room is connected to those spherical rooms, so
I don’t know what it’s used for, or whether it’s a real crystal core library.” Ji Yanran was a little unsure.
"Open one and you'll find out." Han Sen asked Ji Yanran to retreat into the spherical room while he watched Xue Ji open a square black crystal cabinet.
Nothing unexpected happened. The black crystal cabinet was empty and nothing was stored.
Ji Yanran came down and looked at the internal structure of the cabinet, and immediately said with certainty: "That's right, this is the cabinet where crystal nuclei are stored. This should be a crystal core library, but the scale seems a bit too small. A crystal family like this
The crystal core library of the king's relics should be very large. The black crystal cabinet in this room is not even comparable to the crystal core libraries of some small crystal clan relics. It doesn't look like the work of the royal family."
"As long as it's the crystal core warehouse, maybe this is the small vault of the king of the crystal clan." Han Sen looked excited and ordered Xue Ji to continue opening other cabinets.
After opening dozens of cabinets, they were all empty, which made Han Sen slightly disappointed.
However, Han Sen was not willing to return empty-handed and ordered Xue Ji to open all the cabinets one by one. When he got to the eightieth cabinet, he suddenly discovered that there was a glimmer of light shining inside that cabinet.
Han Sen was overjoyed. He quickly walked to the cabinet and took a look, only to find that inside was a golden gemstone, only as big as a fingernail. It was oval in shape and had countless facets. It looked like a shining golden gem.
diamond.
"Is this a crystal core?" Han Sen didn't dare to move and looked at Ji Yanran and asked.
Ji Yanran nodded and said: "This is the unactivated crystal core. Judging from the appearance of this crystal core, after it is activated, it should be the kind of Rubik's Cube guard you have seen."
"It won't start by itself, right?" Han Sen was startled.
Ji Yanran shook her head and smiled: "Definitely not. The crystal cores in the crystal core library are all in a blank dormant state. They will not be activated without instructions from the crystal clan. Now even if you want to find a living crystal clan to come out and activate these crystals,
It is impossible to use a magic cube guard crystal core. This kind of magic cube guard crystal core is a relatively common kind of crystal core, but generally those ruins are second and third level magic cube guards. Among the larger crystal clan ruins, the more common ones are fourth, fifth and sixth level.
The higher the level, the harder it is to see it. The 12th-level Rubik's Cube Guard like the one you saw is very rare and has high collection and research value. If this one is also the 12th-level Rubik's Cube Guard crystal core,
It can be regarded as a priceless treasure.”
Han Sen was overjoyed when he heard what Ji Yanran said. He grabbed the golden crystal core and stuffed it into his pocket. He smiled and said, "Then I'll put it away first."
Ji Yanran knew what Han Sen was thinking, but she just rolled her eyes at Han Sen and said nothing.
With the harvest of the Rubik's Cube guarding the crystal core, Han Sen became more motivated and asked Xue Ji to open the remaining cabinets one by one. After a while, he found another crystal core.
This was a white crystal core. Han Sen looked at Ji Yanran in confusion.
"This is the memory crystal core. The information left by the crystal clan is recorded inside. If your mental power is strong enough, you can directly perceive the contents of the memory crystal core. However, it is basically difficult for human beings to do this.
Relying on instruments can only obtain part of the information fragments in the memory crystal core. Since this memory crystal core is left by the crystal royal family, it may contain important crystal clan information. If part of it can be deciphered, it may be able to advance human technology.
There has been rapid development." Ji Yanran explained.
"Then I'll keep it first." Han Sen was not polite and kept the memory crystal core.
"Did you hear anything?" Han Sen suddenly perked up his ears and looked at Ji Yanran with confusion.
Ji Yanran shook her head slightly: "What sound did you hear?"
Han Sen was about to say something when he heard a tinkling sound fall into his ears, and saw pink crystals the size of duck eggs rolling down from the triangular passage they came down from. In a short time, more than a hundred of them had fallen.
"Parasite core!" Han Sen and Ji Yanran shouted in horror almost at the same time.
