After simply appeasing Tang Wan, Si Nanyuan locked himself in the study on the grounds of official business.

Tang Wan sat alone on the sofa in the living room, looking out the window at the rain that did not stop in a daze.

It didn't take long for Xiao Hei, who ran out of nowhere, quietly jumped onto the sofa, walked to Tang Wan's side, found a comfortable angle on her lap, and lay down cross-legged.

Tang Wan's attention was attracted by Xiao Hei and retracted his gaze.

Seeing the beautiful touch on his legs, Tang Wan certainly wouldn't let it go.

But while masturbating, she suddenly remembered a new way to verify - ask Xiao Hei!

Tang Wan stared at the direction of the stairs for a few seconds, and after confirming that she didn't hear the slightest footsteps, she lowered her voice and opened her mouth.

"Blackie."

"What's the matter?"

"......" and arrogant, "I have a question that I don't understand, I wonder if as the smartest and most knowledgeable Majesty I know, can you help me solve this doubt?" ”

"Stupid woman, for the sake of your sensible sake, I will be merciful to satisfy you. Say, what's the matter? ”

Tang Wan stopped with Xiao Hei's movements, and asked word by word in a particularly serious tone.

"Xiao Hei, do you know Long Jing?"

As soon as he heard the word "Long Jing", Xiao Hei immediately widened his eyes, raised his head, and stared at her.

"Where did you get that word?"

Tang Wan looked at Xiao Hei's reaction, and felt more and more that this dragon crystal was not ordinary.

"It's from the mouth of a strange neurotic! But - it's the dragon's neurosis. ”

"Dragons? Then it is not surprising. ”

Xiao Hei stretched his body lazily, jumped directly onto the back of the sofa, staring at Tang Wan's eyes, "Strange, there are several dragon clans around you, this is the matter of the dragon clan again, why don't you ask them, just ask me?" ”

Tang Wan suddenly felt that Xiao Hei's knowingly asked a little underwhelming.

But if you tell the truth, it won't sound good.

Tang Wan had an idea, and simply followed the routine that Tsundere would like, and continued to praise and coax.

"Because I think that since this is a matter of the dragon clan, then if you ask the people of the dragon clan, the answer you get will inevitably be personal, not very accurate, but it is different to ask you."

"You are not from the dragon family, and you have some contact with the people of the dragon family, and you are also well-informed, and the answers you give must be both standard and objective. That's the kind of answer I wanted. ”

When Xiao Hei heard this, he immediately raised his chin and snorted softly.

Tang Wan understood, this was happy.

Xiao Hei was finished, and decisively jumped back into Tang Wan's arms, found the most comfortable position, and began to explain.

"Dragon Crystal, as the name suggests, is the crystallization of every dragon clan through cultivation, and each dragon can only have one in its body, which can greatly increase the strength of this dragon clan itself."

"However, this kind of cultivation is not a simple cultivation, in addition to enduring ordinary people, it also has to go through many tests, coupled with the right time and place, in order to get a dragon crystal."

"The process of obtaining this dragon crystal is said to be easy, if you really want to do it, it is really too difficult to accurately describe in words."

"Many dragons with very ordinary talents may not be able to cultivate a dragon crystal in their lifetime. But those who are gifted may also cultivate at a young age. ”

"And in each dragon's body, there can only be one dragon crystal, after consumption, although it can be obtained again through re-cultivation, but the difficulty is many times more difficult than the last time."
