Tian Wenxin looked at Li Feng below, engulfed in flames, exuding authority. Her heart inexplicably trembled, and she suddenly thought of her deceased husband, who was also ambitious, determined to lead the Fang Family to greater glory.

But in the end, he left and never returned.

Without an immediate following, Li Feng didn't mind this. He simply told these people who he was.

Li Feng vibrated the Vermilion Bird Wings on his back, the wings stirring up airflow. He tapped his toes on the ground and immediately soared into the sky.

Li Feng hadn't mastered flying yet, but he used the wings on his back to help him jump higher, directly leaping to the entrance platform at a high point. After landing, he looked at the goatee.

"I want everyone here."

The goatee looked at the slightly cracked molten lava lake below, and the temperature of the entire Fire Sea Hell had dropped by more than half.

Looking up at Li Feng, he said with a bitter smile, "The Li Family Head has impressive methods. To others, this is a place of torture, yet it provides you considerable assistance. This transaction is certainly not a loss for you."

The Eighteen Layers of Hell under the Underground Palace City seemed like a terrifying place, but if you could endure it, this was not only hell but also a holy land.

Take this Fire Sea Hell, for instance; it wasn't naturally formed. Below the molten lava lake was a spiritual beast, the Molten Lava Turtle, nearing the Heavenly Level. The lake was formed from the molten lava it spewed.

The place where Li Feng stood earlier was the turtle shell of the Molten Lava Turtle. However, like other turtles, the Molten Lava Turtle belonged to the lazy type, staying still if it could, sleeping for who knows how many years.

Yet, Li Feng's "playing around" on its shell hadn't awakened the Molten Lava Turtle, which was quite unexpected to him.

Li Feng hadn't anticipated that this place would be so suitable for his cultivation, essentially a free cultivation holy land; of course, he wouldn't miss the chance.

In this short time, Li Feng had directly elevated the previously trained Burning Technique to the Sixth Realm, consolidating the meridians in his body into Fire Meridians. The Seventh Level of the Burning Technique involved crystallizing the meridians and the viscera, a process that wasn't as quick.

After all, this wasn't his own place. Otherwise, Li Feng would indeed consider retreating here for a while, expecting substantial gains.

This Burning Technique was the most profound cultivation technique Li Feng had trained in since arriving in Ancestor Dragon City. The Nine Rhinoceros Technique he practiced before was merely a Yellow Level Cultivation Technique, merely enhancing physical power.

In the Heaven Tower, the Hu Ben Battle Technique he mastered also belonged to the martial arts path, focusing primarily on the physical body. However, despite its might, it was unrivaled only in close combat.

Practicing the Burning Technique not only didn't affect the other two techniques but also combined for an effect of greater than two, delivering a punch that transformed force into a tiger, and when channeled through the Burning Technique Fire Veins, the attack instantly elevated from a physical to a dual physical-magical assault.

The power, delightful.

"Ha, just luck."

Li Feng glanced at the goatee. "You brought us here; can't blame me for that. I suppose there are more than just this place?"

The goatee stared at Li Feng, who still wanted to take advantage of the situation, "Family Head Li, if you want to see each place, that would take a long time. The reputation of my duel arena is well-established, and you've seen it with your own eyes."

"Instead, why don't we go up and discuss the price first? If there are no issues, we can sign the contract directly."

The goatee, having achieved his purpose, naturally didn't want to let Li Feng exploit further. If they went to other places and the same thing happened, he wouldn't be able to explain it well.

"It's quite a pity; I really wanted to witness the features of the Eighteen Layers of Hell," Li Feng said, shaking his head.

The goatee stepped aside, thinking to himself, let's just get to business without further ado.

Li Feng had no choice but to follow the goatee, and the three of them turned and entered the passage, ascending the lift out of the Fire Sea Hell.

The slightly dim molten lava lake suddenly trembled, and the consolidated surface suddenly shattered, spewing forth a magnificent power of flame like a volcanic eruption. In the caves on the surrounding walls, the war slaves who were cultivating were all scared stiff.

"Not good, the guardian beast has awakened."

"Run."

Immediately, some war slaves leapt from the caves, heading straight for the passage without hesitation.

The molten lava lake churned for a long time, and suddenly a turtle's head poked out from it.

"Damn, I've fallen to this state, and yet someone is still stepping on me, truly unbearable," the Molten Lava Turtle thought, gritting its teeth, daring only to complain internally.

Thinking back a few hundred years, when it was nearly killed by someone with Vermilion Bird Bloodline, if it hadn't acted wisely and submitted immediately, it would have long become a turtle shell for divination.

Trapped here was a result of that encounter, but fortunately, being a turtle, it could sleep through decades or centuries with ease.

It wondered what year it was now, whether that guy had died yet.

The Molten Lava Turtle thought, directing its gaze to the fleeing war slaves, but to him, they were nothing but ants.

At once, it controlled a stream of molten lava to block their path, turning around to face those stopped war slaves.

Li Feng, unaware of the changes in the molten lava lake after leaving, returned to the Underground Palace City and directly started negotiating the transaction with the goatee.

Ultimately, the two parties reached a transaction for six hundred war slaves, ranging between a few hundred to several thousand, with a final deal amounting to a million Golden Spirit Stones.

"Family Head Li, have you given any thought to war slaves at the Golden Core Stage? Although expensive, the high price is justified."

Li Feng glanced at the goatee, "I could, but I want to see the details first."

"Of course."

"Please wait a moment, Family Head Li. I'll have someone bring it," the goatee said, standing up and leaving the room.

Tian Wenxin watched the goatee leave before approaching Li Feng, whispering, "It seems they deliberately tried to probe you earlier."

Li Feng smiled faintly, "Ha, that's easy to guess. If they didn't have some motive, why would they take us to such a secret place."

"That so-called Eighteen Layers of Hell, calling it hell rather than training holy lands would be fitting. Training there requires high talent; ordinary people would find it hellish, but for exceptionally talented individuals, it's the best training ground."

"This duel arena is quite interesting."

The duel arena was apparently not just for entertainment or making money. If it were, there wouldn't be such an Underground Palace City or the Eighteen Layers of Hell, especially the Fire Sea Hell, which wasn't something ordinary people could create.

With his strength, he found it considerably beneficial inside, not to mention the Foundation Establishment and Magnetic Condensation practitioners. Surviving the tough conditions meant the war slaves were like raw recruits turned elite soldiers.

However, large families wouldn't value them, small families couldn't afford them, and since the cultivation techniques these war slaves practiced each had "flaws," they were mostly used as death soldiers when bought, and generally not in large numbers. 𝒇𝒓𝙚𝒆𝔀𝓮𝓫𝒏𝓸𝙫𝓮𝓵.𝓬𝙤𝙢

Li Feng had just bought hundreds in one go, representing the largest war slave transaction of the duel arena.

As the two were talking, the goatee returned from outside, his expression somewhat heavy.

"Family Head Li, Lady Fang, I have some bad news."
