Heiye Xiao sighed, "We know that when the Emperor went to find the Empress, it had already been eighteen years since she left."

"Back then, the Emperor arranged us, the Hou Tu Eight Guards, but didn't arrange the Three Palaces. The Emperor probably wanted the Three Palaces to disband on their own?"

Heiye Xiao looked at the musical score on the wall, "I think this score is very likely the original score of 'Chan.' Only those who have heard 'Chan' can complete the score and release Pang Gufang."

I followed Heiye Xiao's steps forward and said, "According to you, Bu Ting and Pang Gufang should be from the same era as you. Doesn't that mean you haven't been asleep for long before being awakened?"

Heiye Xiao said, "My sleeping time shouldn't be short, right?"

"I suspect that Bu Ting and Pang Gufang both used other methods to give themselves long lives, waiting for the Emperor."

"I suspect they used demonic spirit secret techniques to refine themselves into semi-demonic beings. Or perhaps they cultivated as ghosts and gods after death. We'll have to wait until we see them to know the specifics."

I looked at the wall and said, "Can you complete this score?"

Heiye Xiao lowered his head and said, "Actually, I don't understand musical scores either."

"I estimate that the only people who can remember the score, besides the Emperor and Bu Ting, are probably two people: one is Jiang Chen, the head of the Four Great Zombies. The other is Pang Gufang."

I grabbed my head and said, "This is troublesome."

Ye Yang said, "How did you trigger the restriction?"

Heiye Xiao said, "I just tentatively struck the stone wall, and then the corpse poison here erupted."

I walked up, gently knocked on the stone wall twice, and used my inner strength to transmit a voice to the secret room behind the stone wall, "Pang Gufang, can you hear me?"

"Pang Gufang!"

"Pang Gufang!"

I asked three times in a row, but no one responded from inside.

Heiye Xiao said, "I've already shouted, she might not be able to hear."

"She can hear." I said in a deep voice, "Pang Gufang, I know you can hear me. As long as you can complete the score outside, we can let you out."

"I don't want to know what happened between you, the Emperor, and the Empress back then?"

"I just want to tell you that your loyalty to the Emperor can only be realized by leaving this prison cell."

"You can't see the Emperor, so how can you be loyal?"

I waited at the entrance of the secret room for a while. Seeing that there was no response from inside, I said, "Forget it, none of us understand musical scores. Let's put this matter aside for now! We'll make plans after we find Jiang Chen."

"Alright!" Heiye Xiao was about to leave when he heard someone in the secret room say, "Wait a minute, I'm willing to complete the score!"

Heiye Xiao nodded at me, meaning: the person speaking was Pang Gufang.

I said quickly, "We have a musician outside, she will tell you the score, you just need to say how to fill it in later."

Qin Xin walked up, grabbed Heiye Xiao's wrist, and said, "Your hand follows my strength, I'll tell you where to draw, and you draw there, don't draw it wrong."

As Heiye Xiao nodded, Qin Xin had already started talking with Pang Gufang.

When the score was nearing its end, a crisp cracking sound suddenly came from the surrounding walls. When I turned my head to look, I saw countless gaps opened in the surrounding walls, and three-edged arrowheads with cold light slowly protruded from the gaps. The arrowheads pointed, blocking all our escape routes.

Heiye Xiao exclaimed, "Pang Gufang, you wrote the score wrong!"

Pang Gufang said, "I didn't, that's how it is in my memory. Did you write it wrong?"

Heiye Xiao roared, "What musician could write the score wrong? Think again."

I waved my hand and said, "Try writing two more strokes down?"

Heiye Xiao said with a cold face, "Pang Gufang, continue to say what comes next."

Qin Xin grabbed Heiye Xiao's hand and moved it slightly back. The sound of the crossbows being cocked rose from all directions like dense rain.

If Qin Xin wrote another wrong symbol, the powerful crossbows hidden in the wall would probably fire a volley of arrows immediately.

The arrows protruding from the wall were obviously armor-piercing arrows specifically designed to deal with heavy armor.

If it were one or two arrows, we might be able to handle it. But if hundreds or thousands of armor-piercing arrows were fired, most of us would be left here.

I whispered, "Retreat!"

As Heiye Xiao's figure retreated a step, a roar came from the direction of the cave entrance.

I watched as the giant stone gate sealed the entrance, and a circle of cracks also appeared along the edge of the wall.

This space from the entrance to the stone wall seemed to be forcibly peeled off. I only felt that the ground under my feet was like a wooden board floating on the waves. As long as I moved slightly, the ground would rise and fall with my steps.

Heiye Xiao said in a deep voice, "Prepare to retreat! I'll protect you out."

Heiye Xiao was about to risk his life.

Nie Xiaochun didn't know how but she actually walked up and grabbed Heiye Xiao's hand, saying, "Let me try."

"You?" We were all stunned.
