The stone tablet was only one person tall, not as tall as Xu Feng had imagined. It was dark blue all over, and its surface was covered with many secret little holes.

There were a total of eighteen strange skeletons surrounding the stone tablet. Not only were there demons, but there were also pure black corpses of demons and translucent corpses of underworld warriors. These skeletons obviously contained the essence of blood.

Seeing the skeletons of the Hades again, Xu Feng's expression was slightly complicated.

The owner of the reincarnation illusion ultimately wanted nothing more than to be reunited with his family.

This shows how deep his obsession was, it was so strong even after his death.

And the things that happened in that memory also surprised Xu Feng. Where is the Mingshan area that everyone mentioned in his memory?

What is the relationship between Chiyu County and the present-day human Chiyu? Is it just the same name?

What kind of sect is Tiexuanmen? Why has he never heard of the white stone slab Yangguan Dao that can make evil spirits disgusted?

Why had he never heard of those evil things he saw in his memory?

Just when Xu Feng was about to walk over and smash the skeletons surrounding the stone tablet, Zi Buyu suddenly stopped him: "Wait!"

Xu Feng raised his eyebrows slightly: "What's wrong?"

His original intention was to transform all these skeletons into his own cultivation. At this moment, Xu Feng already had thirty-one bloodlines in his body. These eighteen skeletons all looked very strange and they were all things that could help him improve his strength.

Wouldn't it be better to understand the stone tablet after turning all of these into strength?

Moreover, the red fighting energy outside Xu Feng's body after he came out of the illusion had turned deep red, and even a wisp of fighting energy had begun to turn into a light orange.

Stopping at this time is like looking at a beautiful woman in your arms but not letting anyone touch her.

As for other distracting thoughts, they can be put aside temporarily in the face of improving your cultivation.

"Something is wrong." Zi Buyu gestured to Xu Feng to walk around the 18 skeletons and take a look.

Under his command, Xu Feng turned around and returned to the original place.

Zi Buyu's face looked a little ugly. "If I'm not mistaken, this should be a formation called the Eighteen Absolute Evil Formation. It will gather the evil spirits from the entire burial pit to here. The thicker the evil spirits, the higher the lethality."

Xu Feng's face changed slightly when he heard this, and the idea of ​​improving his strength faded a little in his mind. He was suddenly shocked and realized the change in his mentality.

After slowly calming down his restlessness, he began to observe carefully.

After a moment of hesitation, he said, "I don't know how many years the evil spirit here has existed. Even if we count from the time when the Human King disappeared ten thousand years ago, I'm afraid that even the strong men at the Dao Soul Realm cannot enter here for ten thousand years. Moreover, the position of these eighteen skeletons seems to be kneeling to the black stone tablet. I don't think it is the killing formation you mentioned."

After observing around, Xu Feng shook his head.

Zi Buyu was surprised and asked, "You also know the formation?"

Xu Feng said calmly: "I understand a little bit."

Zi Buyu frowned and said, "If it is not a killing formation, then what is the purpose of this formation gathering all this evil energy?"

Xu Feng lowered his head and thought for a while, then suddenly took out his spear. He did not touch the obviously special 18 skeletons, but blew away all the scattered skeletons around him and cleared out a piece of open space.

Then he squatted down and began to draw on the ground.

Zi Buyu looked down and saw Xu Feng drawing the position of the corpse.

"Are you calculating?" Zi Buyu was even more surprised. He really thought that Xu Feng only had a rough understanding of the formation. But how could someone who could deduce the formation's logic based on the formation's apparent layout be "slightly aware"?

In the art of formation, there is a strict level division among formation masters, great formation masters, formation masters, formation grand masters and even the highest formation immortal.

Those who know how to deduce formations must be at the level of formation masters or above.

And in the Xuan Realm, let alone great formation masters, even formation masters are extremely rare!

Most people simply set up the formation according to the formation diagram. Such cultivators cannot even be considered formation masters.

The title of formation master is given to masters who can evolve formations on their own and adjust them according to the terrain and on-site situation.

A great formation master must be able to deduce formations and freely combine various formations before he can be given the title of "great formation master".

Among the ten great sects, only the Huichen Sect is a major sect famous for its formation masters.

Only by becoming a great formation master can one become a personal disciple, which shows how difficult it is.

Any of the direct disciples of the Divine Sect who were placed outside would be a powerful figure in the mysterious world.

He had never heard that the Son of God Tianxuan was actually a great formation master?

This discovery really shocked Zi Buyu. For many people, just cultivating to this level at this age is already an extremely difficult thing. In addition to practicing, one also has to comprehend the formation?

It would have been fine if he didn't know that this was Xu Feng, but now that he knew Xu Feng's true identity, Zi Buyu was a little dazed.

"This formation looks like a killing formation, but it actually perfectly utilizes the resentment and evil spirit left in the corpses of these alien warriors. It collects them and uses them as energy."

Xu Feng stopped what he was doing and said confidently: "They are providing energy for the black stone tablet in the middle. This formation is an advanced use of evil spirits."

Zi Buyu looked at the eighteen skeletons with disbelief, as if he was thinking about the possibility that Xu Feng mentioned.

"Don't doubt it, we'll know once we give it a try."

Xu Feng grabbed Zi Buyu's hand and used his energy to condense a blade to pierce his fingertips.

"Hey, hey, hey! What are you doing?!" Zi Buyu reacted, pulled back his fingers and screamed.

Xu Feng ignored him: "Take out the little puppet quickly, or the blood will be shed in vain."

Zi Buyu immediately understood what he wanted to do. After taking out the light puppet, he watched Xu Feng smear his fingertip blood on the puppet and said speechlessly: "Why don't you use your own blood!"

Xu Feng turned his head and looked at him as if he was looking at an idiot: "Don't I have you? Why would I hurt myself for no reason?"

Seeing Zi Buyu taking a deep breath and looking like he was about to curse, Xu Feng changed the subject: "And I need you to attract possible attacks, so that I can have the energy to break the formation. Otherwise, we're just wasting time here?"

Zi Buyu's expression improved. "Okay, but you have to greet me next time. It's very rude to take someone else's blood! What if you have plans against me...well, there are still many evil ways in this world that can use blood to curse others."

Xu Feng's eyes lit up: "You know?"

Seeing Xu Feng's eager expression, Zi Buyu suddenly felt something was wrong. He quickly suppressed the several evil spirit-level martial arts that were about to come out of his mouth and shook his head, saying, "I've only heard of it, but I don't know anything at all."

Xu Feng was suddenly disappointed.

"Hurry up and activate the puppet, get closer to the stone tablet and see if it has any effect." So he said.

Zi Buyu frowned and looked at the blood on the puppet: "Will it be useful to smear some blood?"

Xu Feng chuckled: "This is a small illusion array that simulates the breath of life. It is very useful to borrow fresh blood. Hurry, the effect will not be good after a hundred breaths."
