I narrowed my eyes and said, "Then I'll open the gate to the netherworld again. You help me hold off the people outside. This time, I'm going to trap the entire building inside the gate."

I drew my twin blades, plunged them into the earth, and then used a dagger to cut open both of my wrists, raising my hands and suspending them over the blades. The blood from my wrists dripped onto the hilts. Bai Zhou and Zi Ye trembled madly.

The yin and yang energies, drawn by the blood, shifted back and forth in the limited space. The concrete floor, with the twin blades as the center, cracked into a cross-shaped opening.

A yin wind roared from the ground like the wailing of ghosts, causing a cacophony of ghostly cries and divine howls.

The roar of the netherworld ghosts and gods rose suddenly from the ground: "Who is summoning the gate to the netherworld? Those who dare to open yin and yang shall have their nine generations exterminated!"

I mustered my internal energy and shouted in response, "Li Po, a disciple of the coffin gate's yin-yang lineage. Using blood as a guide, I connect yin and yang."

The netherworld ghosts and gods raged again: "This deity doesn't care whose disciple you are. Daring to open the gate to the netherworld is a capital crime!"

"Take a look at this!" Ye Yang roared, sending the "Prefectural Governor's Token" into the gate to the netherworld.

After a moment, the voice of the netherworld ghosts and gods subsided: "One incense stick...no, I'll only give you the time it takes to drink a cup of tea."

The reason I said I was opening the gate to the netherworld was to make Ye Yang understand that the true name of the secret technique I was using should be called "Jieyin Yinyang" (Connecting Yin and Yang).

The so-called "opening the gate to the netherworld" by sorcerers is just opening a gap in the road to the Yellow Springs. This is not a taboo thing, because the road to the Yellow Springs hasn't reached the netherworld yet. It can't be regarded as "opening the gate to the netherworld" in the true sense.

More importantly, the road to the Yellow Springs itself has countless gaps that can accommodate the entry and exit of ghosts.

Originally, the ghost messengers should have all gone to a fixed location to pick up and drop off ghosts. However, both humans and ghosts like to take shortcuts. Even the ghost messengers are using these gaps to enter and exit the road to the Yellow Springs, so they don't care who opens a gap in the road to the Yellow Springs.

The Jieyin Yinyang (Connecting Yin and Yang) I used skipped the road to the Yellow Springs and directly opened a gap in the underworld. Not to mention, how can the dignity of the underworld allow others to easily provoke it? But just connecting yin and yang is equivalent to committing a great taboo.

Those who Jieyin Yinyang (Connect Yin and Yang) are bound to die!

Even if he doesn't die on the spot because he runs out of blood, he will be beheaded on the spot by the ghosts and gods of the underworld, or even annihilated in both body and spirit.

Therefore, Jieyin Yinyang (Connecting Yin and Yang) belongs to the forbidden arts of the sorcerer's path. Even if someone knows how to use it, no one is willing to use it!

Over time, "Jieyin Yinyang" (Connecting Yin and Yang) gradually became lost. It was precisely for this reason that I told Ye Yang that I was opening the gate to the netherworld.

In a short moment, the yin wind in the room faintly carried a baleful aura, which was the prelude to the imminent arrival of the netherworld's astral wind.

Shi Yu outside the door panicked immediately: "Lin Sihan, quickly order a general attack. Don't let him Jieyin Yinyang (Connect Yin and Yang). Li Po is a madman who dares to risk his life."

Lin Sihan deliberately raised her voice and said, "Risking your life is not the same as courting death. I don't believe he really dares to Jieyin Yinyang (Connect Yin and Yang)!"

Lin Sihan was right. In fact, at that time, I didn't have the determination to die, and I didn't open the yin-yang barrier all at once, but was slowly pushing the channel inward.

Otherwise, the ghosts and gods of the underworld wouldn't have been reprimanding me just now, but would have jumped out of the underworld and executed me on the spot.

Lin Sihan is trying to compete with me in patience.

With a sudden tremor of my arms, the blood from my wrists gushed out frantically. The two curved blades wailed like ghosts, sharp and ear-piercing, and the gap on the ground was torn open a few more inches.

As the yin wind raged in the room, Ye Yang suddenly retracted his long sword. The door of the room was immediately pushed outward by the gale, smashing into pieces against the wall. The yin wind in the room surged out, sweeping away the ghosts outside.

Shi Yu retreated repeatedly, shouting, "Attack, attack, attack quickly!"

Lin Sihan's voice was still as cold as water: "The netherworld's astral wind hasn't blown up yet, what are you afraid of? Isn't it good to wait quietly and watch Li Po and the others be torn into pieces by the astral wind?"

The original meaning of astral wind in Taoism refers to the wind in the high sky. In the path of sorcery, it is further divided into several types, but no matter how it is divided, there is one common characteristic: that is, "the astral wind is like a blade, and even a golden body can hardly withstand it."

The netherworld's astral wind is one of them. It is not only extremely fierce, but also carries the aura of yin and evil. Even immortals may not be able to withstand a single blow from the astral wind if they want to cross the netherworld.

As long as I probe a little further, I may encounter the netherworld's astral wind. Even if only a trace of it is drawn in, Ye Yang and I will be torn to pieces.

Maybe before our bodies hit the ground, we will be blown into bloody froth by the astral wind.

But if I don't continue, I won't be able to deceive Lin Sihan. Ye Yang and I have no vitality to speak of.

Just as I was in a dilemma, Ye Yang took two steps back and leaned against me. His voice, transmitted through internal energy, then sounded in my ear: "Don't be afraid, and don't open your mouth. The worst that can happen is that we'll die together. If you stop, our deaths will be worthless."

It's not that I'm afraid of risking my life, but that I'm afraid of bringing Ye Yang into it.

Now that I have Ye Yang's words, I don't need to consider anything else.

I laughed wildly, lowered my hands, picked up the two curved blades, connected the hilts together, and moved my hands slightly to grip both blades at the same time.
