This was why the Netherworld Kingdom had been able to withstand so many covetous eyes. With its fighting strength plummeting so drastically, anyone who wished to deal with the Netherworld Kingdom would have to pay an enormous price.
Moreover, the Netherworld Kingdom was even more powerful than ordinary Emperor Lord Inheritances. Unless someone like Ye Xiwen mobilized the Myriad Realms to launch a campaign against it, the odds of success were simply too low.
Ordinary people could not endure laws as extreme as those of the Netherworld Kingdom. Yet it was precisely under such laws that the Netherworld Kingdom could nurture so many powerful experts. It was absolutely not as simple as merely burying someone and allowing them to revive.
"Ye Xiwen, you are quite bold. Throughout all of history, there have not been many with such audacity, but they all had to pay the price!" The Underworld Emperor stared coldly at Ye Xiwen, his eyes crimson like two scarlet gemstones.
"Hmph, you are nothing but a filthy rat that hides in the darkness and launches sneak attacks. A man who cannot stand the light dares to bark before me?"
Ye Xiwen's words nearly made the Underworld Emperor jump in fury. Every sentence Ye Xiwen spoke brought up how he had sneak-attacked the Lord of the Underworld. To an Emperor Lord-level expert like him, that was also a humiliation.
After all, experts who had reached that level still doing such a thing was one matter if it had been done to an enemy—it could at least be understood. But the Lord of the Underworld and the Underworld Emperor had always joined hands against their foes, only for him to stab his ally in the back. Even if such a person was an Emperor Lord, he was not worthy of respect.
