Compared to the evil spirits in the underworld, he couldn't even be bothered to look at them.

The woman's eyes widened in shock. "Just a wave of the hand?"

She had studied this formation diligently, but she never expected it to be so easily defeated by Ying Liu.

Upon seeing this, Yunhai's eyes darkened. He raised his left hand and slashed his right hand across his left, causing blood to flow from his palm immediately.

A surge of Yin energy erupted around Yunhai. "With blood as a sacrifice and oath as a covenant, Lord of Yin Spirits, come!"

As soon as he finished speaking, a massive star array appeared before him, surging with yin energy, clearly far superior to the woman's star array.

The next instant, a ghostly figure emerged, wielding two swords, clad in black armor, with crimson light flowing from its pupils.

The evil spirit roared, and its surging aura swept out, stirring up a whirlwind.

Its immense power caused the surrounding void to tremble slightly, indicating that it was an extremely powerful being.

Seeing this, Ying Liu finally showed a hint of interest, "That's interesting."

The evil spirit roared and then lunged at Ying Liu, raising its shoulders high as it slashed at him.

Just as he was about to get close, Ying Liu stretched out one hand, and the Myriad Soul Flute appeared in his hand.

Then he blew the Ten Thousand Souls Flute, and a wisp of yin energy spread out from the flute, surrounding the yin spirit.

The spirit's steps were halted by that force, and then it began to let out painful howls, as if it were struggling violently.

Seeing this, Yunhai frowned. "What's going on?"

He had practiced the art of unorthodox methods for many years, but this was the first time he had encountered such a strange situation.

After a struggle, the spirit stopped wailing and seemed to calm down.

He then suddenly turned around and raised his twin swords, aiming them at Yunhai.

Upon seeing this, Yunhai was utterly shocked. "How is this possible?!"

Logically speaking, the spirits he summoned should have absolute obedience to him.

But now they're turning on him with swords?

This is really weird!
