Nangong Du picked up the lark and ran towards the Yin Yang Tower. The people of Chidosa Pavilion also went up to the tower one after another, lying on the outer wall of the tower like spiders, but they could not find a place to enter the tower. Nangong Du didn't have a flying hook, and he had a lark, so he had to sneak quietly from the ground and approach the tower.

The Yin and Yang Tower is a white marble octagonal imitation pavilion tower, so it is white from a distance, a total of three layers, there is an octagonal Sumeru seat below, each side is engraved with the gossip map, it is a real Taoist tower. Although this surprised Nangong Du slightly, what was even more surprising was that it had no door. Every position where there should be a door was sealed by a boulder painted with a mural, Nangong Du reached out and touched it, and the stone walls of those sealed doors were smooth and cold, like jade walls. The stone wall is painted with the gods of the underworld, Nangong Du turned around the tower but couldn't find the entrance, could it be that this tower was sealed? The jade key in his hand is useless, because there is no lock hole at all, how to open it?

The sky was getting brighter and brighter, the fight between the Thousand Bird Pavilion and the golden-robed man was still continuing, the sound of swords intersecting, and the sound of screams and screams were endless, Nangong Du was troubled, and he circled around the tower, but found nothing. He sat down discouragedly leaning on a jade bi, looking at the lark's sleeping face, feeling pity in his heart, if it weren't for his unintentional instigation, the lark would still be in front of the Thousand Bird Pavilion Lord's subordinates, and it didn't seem to be anything bad. I have to save the lark's life no matter what, so that I can be worthy of this poor girl. So, he calmed down and carefully examined each mural, even the beaded ornaments on the corners of the characters.

Finally, he found that a jade wall was not painted with the gods of the underworld, but a white-bearded old man, whose immortal wind bones were mixed in the portraits of these gods of the underworld, and the situation was naturally different, but if it looked at first glance, it was not easy to find the difference. Nangong Du carefully looked at this jade wall, and saw that the Taoist painted on the wall had a peaceful expression and an indifferent gaze...... Gaze, Nangong Du's heart moved, and when he looked at the eyes carefully, they were all two hollows, and there was a heavenly eye on his forehead, which was also hollow, just three narrow holes, Nangong Du's heart moved, and he immediately took out the iris knife, cut the palm, and the blood stained the knife, and the blade of the iris knife immediately bloomed, and he took advantage of the situation to aim the three blades at the three holes and insert them. Sure enough, with a "click", the entire wall slowly opened......

Nangong Du was surprised and delighted, and walked in cautiously with the lark on his back, and the appearance of the inside of the Yin Yang Pagoda was impressively revealed in front of his eyes. I saw that the first floor of the tower was an empty hall, the candles were dark, and the walls around it were full of layers of wooden lattices, full of bottles and cans, such a formation made Nangong Du quite familiar. Nangong Du slowly walked to the hall, only to see that there was a staircase in the corner of the hall, which was pitch black, and it was estimated that it led to the second floor, and the so-called Yin Yang Mirror should be upstairs. Nangong Du did not hesitate, and walked upstairs with the lark on his back, he wanted to see what rare treasures were in this tower.

The second floor is a simple dwelling, with a large bed, desk, and other things, but there are no swords, no curtains, and no show screens and curtains, so you can't tell whether the owner of the house is a man or a woman. Nangong Du didn't stay here for long, and continued to walk to the third floor.

Because the tower is pointed, so the more you go up, the narrower and darker the corridor, the entrance of the third floor has a faint light throughout, Nangong Du stared at that little light, that light may be from the candle flame, gently undulating and swaying, but in Nangong's opinion, it seems to be a strange breath. There are also three steps, two steps, and the last stage - Nangong Du finally stood at the entrance of the third layer, his and the lark's bodies completely blocked the light, and the stairs behind him fell into complete darkness in an instant, disappearing the way to retreat.

It was a gloomy room filled with white candles. In the center of the room stood a shade-piercing stone about eight feet long, and the surface of the stone was covered with a blood-red, root-like thing. It seems to be beating faintly, like human blood. And on the square of the stone, hanging a naked man, with his hair covering his face, and blood slowly flowing down his body, flowing through his chest, thighs, and finally on the tips of his feet, and dripping on the penetrating stones...... This scene has a strange ferocity that cannot be visualized, Nangong Du stood at the door, and he couldn't come back to his senses for a long time.

Suddenly, the man hanging on it let out a soft sigh, although it was slight, but it was like a morning bell and a dusk drum that woke Nangong Du up. "Could it be that the man who hung him is still alive?!" He thought to himself, so he placed the lark in the doorway, and he walked towards the stone step by step. When I walked close to the stone, I found that there was a person lying faintly inside the stone, which should be a sarcophagus, and the front of the sarcophagus was inlaid with a ...... Eyeball.

The eye was blood-red, for the blood of the man hanging on it was dripping right on this eyeball. This was really beyond Nangong Du's comprehension, and just when he was dazed, the person above made a sound again, no longer a sigh, but a voice in his throat, as if he wanted to speak. Nangong Du was sure that he had heard correctly, and looked up at the man, and at the same time stretched out his iris knife and pointed it directly at the door of the man's face.

The tip of the knife approached the man's face, and Nangong Dudao's wrist moved, pulling the hair off the man's face, revealing a pale and shriveled face. And that face - let Nangong Du feel like being hammered.

That face is somewhat similar to him, that face was so majestic, no matter how shriveled and old that face is, Nangong Du can recognize it at a glance - father.

Yes, it's Nangong Ling. It's his father who he thought he had already died under the sword of the ghost car!

"Nope! No! No-" Nangong Du shook his head frantically, his screams piercing the sky......
