Standing under the Stygian Tower, Fang Ling immediately released his five senses, and the defensive array outside the tower quickly appeared in front of him like a cocoon, in a short period of time, he understood the external structure of the Stygian Pagoda clearly, and secretly praised it in his heart, as Shi Sanfu said, the defense of this tower can be called perfect, if there is really a magic circle or magic weapon in the world that can penetrate this kind of magic circle to suck away the undead, it is simply an artifact in the world.

Then, everyone walked into the tower of the underworld, as soon as they entered the tower, everyone was attracted by the structure of the tower, the tower is not big from the outside, but as soon as they walked in, they found that the area was more than ten times expanded, showing the jade-colored jade wall like flowing water extended, constructing a cage one by one, each cage is a vast space, as long as you penetrate the consciousness, you can perceive the many wandering spirits inside.

Fang Ling suddenly asked as he walked, "Looking at the records on the paperwork, the missing necromancers are not limited to which layer they are, and even the time is not fixed. ”

The commander who led the way replied respectfully: "That's right, there are dead spirits missing on each of the twelve floors of the entire tower, and I once saw it with my own eyes. ”

"Have you seen it with your own eyes?" what kind of scene was that?" Fang Ling hurriedly asked.

The magistrate replied, "It's like being swallowed up by something, and it's gone all at once." I couldn't find it anymore. ”

At this point, everyone has come to the center of the tower of the Stygian Tower, the center of the tower is a stone pillar that rises from the bottom of the tower and runs through to the top of the tower, this stone presents a jet-black color, and there are a large number of strange-shaped protrusions on the surface, as if a skull is condensed, and there are dense needle tip holes on it.

Fang Ling suddenly remembered something. Chao Na asked the official, "Could it be that this is a roe blue stone that is rare even in the underworld?"

The official gave a thumbs up and said with admiration: "Childe is really good eyesight, he can recognize the origin of this thing at a glance, this is the Badge Blue Stone." ”

Fang Ling's heart suddenly moved, and he asked, "Could it be that the Eight Treasures Mansion has a badge blue stone?"

The official shook his head and said: "This is not it, if I remember correctly, this should be the treasure captured in the thousands of battles and the ghost domain war, and then it was used to make the □□ of the formation." ”

The corners of Fang Ling's mouth hooked up a smile, and said, "You don't need to look at this tower anymore, let's go back." ”

Everyone thought that he was getting tired, so they all followed him out of the Dark Sky Tower, and then found that Fang Ling did not continue to walk towards his residence, but instead rushed in the direction of the ruins of Ghost Head City.

Coming to the entrance of the ruins, Xiao Xue couldn't help but ask, "Fang Lang, what did you find?"

Fang Ling looked at the ruins underground, and said lightly, "I didn't find anything, but I thought of a place we missed. ”

"Where did you miss it? We have searched all over the upper and lower layers of the city, with my five senses of the bear and the wolf, even if there is a secret path here, it can't hide my five senses, even if there are any magic weapons and magic circles, it can't be hidden. Xiong Wu Wolf patted his chest and reassured.

Wu Tianbao also said in a deep voice: "Yes, Fang Gongzi, we have also checked carefully, there is indeed nothing strange here." ”

Song Ying'er opened her eyes wide and speculated, "Could it be that it has something to do with the roe blue stone that His Highness just asked?"
