After half a day of traveling, Wang Ruoxie and Tang Miaoyin finally arrived at the location of the Underground Blood Cave.

This was a dilapidated small ancient city, with most of the buildings within constructed from earth and stone.

Gusts of wind occasionally swept through, lifting waves of yellow sand; thus, this ancient city was also known as Sand City.

All around Sand City lay a vast desert, with billowing yellow sand that made the air and environment extremely uncomfortable.

However, despite this, Sand City remained very prosperous due to the entrance of the Underground Blood Cave being located within the city.

But because of this, the people who came to Sand City were all quite strong, and Martial Cultivators in the Energy-Introducing Realm dared not enter easily.

Although Sand City was not far from the Royal City, it remained exceedingly chaotic, with fights and killings commonplace.

It was even possible to be suddenly killed while walking on the street and robbed of your belongings.

At this moment, both Wang Ruoxie and Tang Miaoyin lifted their steps and walked towards Sand City.

However, just as they were about to enter the city, two figures emerged from the city gate.

They were two middle-aged men, one with a scar on his face, and the other with skin black as coal; both had slight cold smiles at the corners of their mouths, clearly not good people.

"If you want to enter Sand City, you each must hand over a Lower Grade Spirit Stone, so the two of you will need two Lower Grade Spirit Stones,"

the scar-faced man said coldly to Wang Ruoxie and Tang Miaoyin.

"As far as I know, Sand City does not have any rule about a city entry fee,"

Tang Miaoyin said coldly, her eyebrows slightly furrowed.

Wang Ruoxie also frowned; they naturally had two Lower Grade Spirit Stones, and even twenty or two hundred Lower Grade Spirit Stones they could afford, but they would not allow themselves to be extorted so easily.

"Beauty, if you don't have Spirit Stones, let me give you a kiss, and I'll let you in, how about it?"

The black-faced man said with a lecherous smile as he looked at Tang Miaoyin.

Hearing this, a cold glint flashed in Tang Miaoyin's beautiful eyes.

Wang Ruoxie found it amusing; if this guy knew the woman before him was the Seventh Princess of the Royal Family, who knows if he would still be so brazen.

"Kid, too bad you're not a beauty, so you must hand over a Lower Grade Spirit Stone,"

the scar-faced man sneered at Wang Ruoxie.

"What if I don't give it?"

Wang Ruoxie replied with a faint smile.

"If you don't, then I'll take your life,"

the scar-faced man barked, and as his words fell, a violent aura swept out from him.

Soon after, a large saber appeared in his hand, and without any hesitation, he slashed towards Wang Ruoxie.

"Hiss!"

In the next instant, with a soft sound, a head fell to the ground.

"Scar…"

Seeing this, the black-faced man's expression changed drastically, and he looked at Wang Ruoxie with terror.

He initially thought the man and woman before him were easy targets from whom he could extort some Spirit Stones, but he had not expected to provoke a formidable foe.

"You do it, or shall I?"

Wang Ruoxie asked Tang Miaoyin.

"Leave it to me,"

Tang Miaoyin nodded slightly and then drew her longsword, easily slaying the black-faced man.

Sand City has no rules; strength is everything. It is a paradise for the strong and a hell for the weak.

Those who come to Sand City either kill or are killed.

The two of them ignored the corpses on the ground and continued to walk into Sand City.

"Indeed, the people who come to Sand City are not weak."

After entering Sand City, Wang Ruoxie noticed that the passersby all had at least the First Layer of Element Transformation Realm cultivation, and Martial Cultivators in the Energy-Introducing Realm were almost unseen.

Moreover, Sand City was much more bustling than he had imagined; people were coming and going, and the ringing of haggling and vendors shouting came from the shops lining the streets, creating a lively atmosphere.

Unlike other cities, almost everyone here carried weapons such as longswords, and many even wore armor, as if ready for battle at any moment.

As for the items sold in the shops, they were principally cultivation resources and weapons like swords, armor, and shields.

"Boss, how much for this bottle of Fire Lion Beast essence blood?"

At this moment, Wang Ruoxie heard a voice coming from a shop ahead, which caught his interest.

The Fire Lion Beast is a Tier Three Middle Level demon beast, with strength comparable to a Martial Cultivator at the Middle Stage of the Element Transformation Realm.

If he devoured and refined the essence blood of the Fire Lion Beast, he would surely break through to the Element Transformation Realm in a short time.

"Let's go inside and take a look,"

Wang Ruoxie said to Tang Miaoyin, and the two of them stepped into the shop.

Demon beast blood can be refined into Blood Pills, which assist Martial Cultivators in nurturing their qi and blood.

Moreover, demon beast essence blood can serve as materials for Alchemy, Artifact Refining, and Array Formation, and some Martial Cultivators can even refine demon beast essence blood through secret techniques to enhance their cultivation and strength.

On the shop counter were many porcelain bottles, labeled to show that they contained different sorts of demon beast essence blood.

Evidently, this was a shop specializing in selling demon beast essence blood.

To Wang Ruoxie, demon beast essence blood is a cultivation resource and a treasure to directly increase cultivation. As long as he has enough essence blood, he can continually improve his cultivation.

However, as one's cultivation improves, the tier of demon beast essence blood required also becomes higher, and higher-tier demon beast essence blood is increasingly precious.

Even the essence blood of a Tier Three Low Level demon beast costs ten Lower Grade Spirit Stones per bottle.

And the essence blood of a Tier Three Middle Level demon beast costs at least one hundred Lower Grade Spirit Stones per bottle and is rarely available.

Wang Ruoxie looked over and saw a young man bargaining with the shop owner over the Fire Lion Beast essence blood.

"Boss, there are at most ten drops of Fire Lion Beast essence blood in this bottle, yet you're asking two hundred Lower Grade Spirit Stones. Isn't that too expensive?"

The young man said to the middle-aged shop owner.

Many people around nodded in agreement; although the Fire Lion Beast is one of the strongest among Tier Three Middle Level demon beasts, selling ten drops of its essence blood for two hundred Lower Grade Spirit Stones is indeed too expensive.

"Ten drops of ordinary Fire Lion Beast essence blood indeed aren't worth two hundred Lower Grade Spirit Stones, but what if it's Fire Lion King's essence blood?"

The shop owner said with a faint smile.

"What… it's the Fire Lion King's essence blood?"

Hearing this, everyone around displayed looks of astonishment.

The Fire Lion King, the king among Fire Lion Beasts, possesses strength equivalent to a Martial Cultivator at the Late Stage of the Element Transformation Realm.

If this bottle truly contains the essence blood of the Fire Lion King, then two hundred Lower Grade Spirit Stones is not just not high, but actually too low.

A strange light flashed in Wang Ruoxie's eyes; he knew well that while the Fire Lion King is still a Fire Lion Beast, its strength and bloodline far exceed those of ordinary Fire Lion Beasts.

And because of this, the energy essence contained in the Fire Lion King's essence blood is comparable to that of ordinary Tier Three High Tier demon beasts.

"Boss, if this really is the Fire Lion King's essence blood, even just ten drops should far exceed the value of two hundred Lower Grade Spirit Stones, shouldn't it?"

The young man asked the shop owner skeptically once more.
