She ran her fingers along the surface of the stone and felt a familiar sensation.

Yes, this is a raw crystal!

She had previously worked with Shui Duoduo to cut through a lot of raw stones.

Fourteen years into the apocalypse, it seems that crystals have not yet been discovered.

After all, no one would be so bored as to go and cut open a stone to see what's hidden inside.

Xin Sui, wielding the Dragon Tooth Dagger, swiftly and effortlessly dismantled the stone, as if slicing tofu.

Inside the fist-sized rough stone was a crystal the size of a tangerine, and it was white.

Mystic crystal comes in six colors: black, blue, white, yellow, red, and purple.

The value increases as time goes on.

One white crystal coin = 100 green crystal coins = black crystal coins.

This single white crystal is enough to make a down payment on a house in Bright City in 277 years after the apocalypse...

Ruan Peipei: "Is this crystal?"

In Fangfang's view, the crystal-like stone in Xin Sui's hand was shrouded in a thick, misty layer of profound energy.

This is definitely not crystal.

Xin Sui shook his head: "No, this is Xuanjing (mysterious crystal)."

Qiao Lu: "What is Xuanjing?"

Xin Sui handed her the white crystal, saying, "Use this as a crystal core and try to guide the profound energy inside for cultivation."

Qiao Lu took it and did as instructed.

A moment later, she showed a surprised expression, "This mystic crystal can be used for cultivation! Moreover, the mystic power contained in it is much richer than that contained in the crystal core. When absorbing it, there is no feeling of stagnation at all, it is incredibly smooth."

Everyone else's eyes widened, and their breathing became heavier.

His gaze toward the crystal became intense.

Xin Sui: "You should all take turns experiencing it."

So the crystals were passed down from Qiao Lu one by one.

Finally, it returned to Xin Sui's hands.

The luster of the crystal has dimmed somewhat.

Xin Sui explained to the group what Xuanjing was and told them about the dangers of using crystal cores for cultivation.

"The crystal core contains violent energy. Although it can be used for cultivation, over time, the violent energy accumulated in the body will hinder advancement."

"Even one's temperament can gradually become irritable and manic, and in severe cases, it can even lead to death by bursting the body."

"This is also why people use crystal cores to cultivate, but the progress becomes slower and slower, and it becomes more and more difficult to advance."

Xuanwei: "No wonder you told us to stop using crystal cores for cultivation."

Xin Sui: "Mystic crystals are essentially the same as crystal nuclei, except that crystal nuclei are nurtured by living organisms, while mystic crystals are nurtured by mountains and rivers."

"The crystal core has a short incubation period, but it contains violent energy, posing a great risk to cultivation."

"Mystic Crystals do not contain any violent energy, making them safe to cultivate, but they take a long time to develop and produce very little."

After listening to Xin Sui's explanation of crystal nuclei and mystic crystals, everyone felt they had gained a lot of knowledge.

Fangfang stared intently at Xin Sui, "How did you know all this?"

How could she know so much about the mysterious crystal that had never been discovered before?

Xin Sui: "Because I came from the future, this knowledge is basically common sense in the future."

Fang Fang: "..."

Is it fun to mess with me?

If you don't want to tell him, fine, but you make up this nonsense to deceive him.

Xin Sui: Sigh, no one believes me when I tell the truth.

"If you don't believe me, then so be it."

While the group was talking, Xiao Guang lay on the coffee table and curiously poked the shiny stone.

Children, like dragons, have no resistance to shiny things.

To his surprise, as soon as he touched the stone, a cool and gentle current of air flowed into his body.

The stone's luster quickly faded, and in an instant, it turned into a pile of grayish-white powder.

Startled, Xiao Guang quickly withdrew his hand.

This scene did not escape the eyes of the adults present.

Xin Sui grabbed his hand and quickly checked him over. "Xiao Guang, is there anything that's bothering you?"

Xiao Guang shook his head.

Xuanwei was initially delighted: "Could it be that my Xiaoguang has awakened a special ability? Otherwise, how could he absorb the Xuan power in the Xuan Crystal?"

His brows furrowed again, his face showing concern: "But this speed is too fast, faster than even us adults who are used to cultivation."

Xin Sui was so concerned that she lost her composure and didn't initially think about awakening her supernatural abilities.

Xuanwei reminded her before she realized what was happening.

But is that even possible?

Wasn't Xuan Tu captured by the Lou family at the age of 10 and forced to swallow a crystal core before awakening his superpower?

Did the butterfly effect she caused after she transmigrated have such a big impact?

Xiao Guang was frightened by the adults' attitude and buried his head in Xin Sui's arms.

"Xiao Guang didn't do it on purpose."

The little guy's voice was timid, as if he thought he had done something wrong.

Xin Sui's heart softened, and she picked him up, saying softly, "Uncle knows, we don't blame you, we were just worried you'd get hurt."

Xuanwei watched from the side and felt that Xiaoli was more like a mother than she, the mother herself.

Of course, she wasn't jealous at all of Xiao Guang's closeness to her; she just felt fortunate.

Whether Xiao Guang has awakened superpowers or not, we'll find out by verifying it.

Xin Sui took out a crystal coin. "Xiao Guang, come on, hold it and try—"

She swallowed back what she was about to say, startled.
