Although that joint attack wiped out most of the demon beasts in the human living area, the number of demon beasts was far more than these, and there were still many demon beasts entrenched in the area outside of human life, which was called the "Life Forbidden Zone", a barren place that was not suitable for any human habitation. As for the area where Shen Yanxiao and they live now, although it has been cleaned up once, most of the ones that have been cleared are low-level demon beasts, and those high-level demon beasts with the ability to transform are still hidden in the city where humans live, but they have become very cunning, and after every attack, they will leave the scene of the crime without a trace, and it is difficult to hunt down.

In the Longxuan Empire, the demon beast is a very terrifying existence, and in any city, as long as it is rumored that someone has been attacked by a demon beast, it will immediately cause a great shock.

Shen Yanxiao has more or less understanding of everything in this world during this time, and she has also heard a little about demon beasts, but she doesn't know how this ferocious creature is related to her breaking the seal?

"I need to absorb the power in the demon beast crystal nucleus to recover my strength, as long as my strength recovers, I can naturally help you unlock the next layer of seals." ’

"......" Shen Yanxiao was slightly stunned.

When a monster dies, it leaves behind a magic core that stores power, and a monster also has a "core" that stores power, called a crystal nucleus. The Demon Core is very popular because it can be synthesized into the weapons of those who cultivate magic and fighting spirit, causing it to generate a powerful force, and the more powerful the Demon Core left behind after the death of the demonic beast, the more powerful it becomes.

But the crystal nucleus is different from the magic core.

The power in the magic core is very pure, and people can use it directly, but the crystal nucleus is mixed with a very strong dark aura, although the power of the crystal nucleus is also very strong, but few people can resist the dark aura that emanates from the crystal nucleus.

If someone uses a weapon synthesized from crystal nuclei for a long time, then his body will soon be eroded by the dark aura in the crystal nucleus.

In Shen Yanxiao's words, at least he will go mad, and at worst he will be heroic and righteous.

Only some masters with extremely strong mental power have the courage to use crystal nuclei, and they only dare to use crystal nuclei that are lower than their own level.

In any case, the crystal nucleus is a chicken rib for people, tasteless to eat, and it is a pity to abandon it.

She didn't expect that such a chicken thing was actually the key to repairing and recovering her strength. Let's just say that in terms of taste, someone is really a little heavier... Slightly heavier......

"It's not difficult to get crystal nuclei, several countries have joined forces to exterminate a lot of demon beasts before, and a large number of crystal nuclei are in the hands of various countries, and no one wants these things, now you can buy a large number of them at a random auction." Shen Yanxiao used the knowledge of this period of evil supplementation, no matter whether the taste of cultivation was heavy or not, in short, this matter was not difficult to do.

Now the only question is......

She's poor!

As an idiot! As a waste! As a professional rice worm!

The Suzaku family only cares about her food and clothing, how could they give her that kind of thing called "pocket money"?

Except for the two purses that were taken down from the two little maids before, Shen Yanxiao can be said to have a clean breeze on his sleeves, and his pockets are cleaner than his face. Although the crystal nucleus is not as expensive as the magic core, it is not a rotten cabbage, and with the little money she has in her hand now, it is okay to buy one or two low-level crystal nuclei.
