He already considered Li Yu as a rival, but he still underestimated Li Yu's growth rate.

The arrow's immense force even made it difficult for him to hold the Yellow Springs Halberd.

As the Heart-Piercing Strike was triggered, Mingyuan's vision suddenly went black, and he staggered, unable to stand steadily.

The life force in this body dissipated rapidly, and even though powerful energy continuously maintained the operation of the other organs, it was still unable to resist the process of being forcibly killed.

Mingyuan's expression hardened, and a large amount of white mist instantly erupted from his body, managing to hold back death!

Even Li Yu's arrow couldn't withstand it, and Ming Yuan felt he had lost face and was extremely humiliated!

He reached out and grabbed the white mist in front of him, letting out a low, unwilling roar:

"The Gates of the Underworld—"

As the Netherworld opened its mouth, the ghostly spirits and deathly energy attached to the Yellow Springs Halberd, which was inserted into the bone stone, began to surge wildly, appearing extremely excited.

"Boom..."

A large white gate slowly rose from the white mist and appeared behind Mingyuan.

The gate was dozens of feet high, covered with countless silver dragon chains and restrictions, exuding a mysterious aura.

It seemed to conceal endless darkness, inspiring awe and fear.

"Thump." The door kept shaking and making loud noises, as if something inside was constantly banging against it, trying to escape.

A terrifying aura swept over them, and the flames on the Phoenix Bow were nearly extinguished by the chilling air.

Li Yu also sensed the terror behind that door; even the Nightmare Beast trembled with fear and couldn't help but speak:

"Li Yu, run away. A wise man doesn't fight a losing battle. We can kill him later."
