Seeing that Li Longxing easily killed the young sect leader and others of the Blood Skull Sect, Tianji admired him, but at the same time she couldn't help but feel a little worried.

She took a step forward, took Li Longxing's arm and said, "Brother Li, there are a lot of people from the Blood Skull Sect this time. If you kill their young sect leader, I'm afraid they won't let it go. ."

Li Longxing smiled slightly when he heard this, "Don't worry, isn't it just a blood skull sect? It's fine if they don't come to mess with me. As long as they dare to come, I will kill one of them and two of them. Kill both of them individually!"

"Haha, Master, you are so domineering!" Hearing this, the Blood Demon Ancestor couldn't help but give a thumbs up and expressed his heartfelt praise.

"Okay, stop flattering, how are things going?" Li Longxing got back to business!

"Don't worry, Master, everything has been taken care of." The Blood Demon Ancestor said with a smile, "Thanks to Princess Tianji this time. If it weren't for her assistance, many people wouldn't believe me here. There will be a treasure map!"

"No, I'm just helping from the side!" Tianji smiled modestly.

"You two have worked hard this time!" Li Longxing smiled and said to the Blood Demon Ancestor, "Let's go, take me to the auction site to see it!"
< br />"Master, please!" The Blood Demon Ancestor made a gesture of invitation and led the way, heading straight into the depths of the mansion!

Soon, everyone came to the back garden of the big house!

The entrance to the underground black market is in a rockery in the back garden!

The Blood Demon Patriarch pointed his finger, and the man-made rockery immediately moved to both sides, revealing a dark entrance.

"Greetings to the ancestor!" As the entrance opened, the two Blood Demon Sect disciples guarding inside quickly saluted respectfully!

“No need to be polite!”

The Blood Demon Ancestor waved his hand, took Li Longxing and Tianji, and jumped into the entrance!

Below the entrance is a passage about half a meter wide, winding all the way to the depths of the ground.

Li Longxing looked into his mind and found that there were many powerful magic taboos secretly arranged in this passage, and the defense was quite good.

Arriving at the end of the passage, a thick black stone door blocked the way!

The Blood Demon Ancestor pointed out the secret, and the black stone door immediately opened slowly!

The stone door opened, revealing a huge underground cave behind it.

However, the cave was built like a palace.

The surrounding walls were all polished smooth and inlaid with many fist-sized luminous pearls, illuminating the entire cave as bright as day..

In the half-empty wall on the east side of the cave, hollows were dug out, and special boxes were built inside.

In the cave hall, a stone platform about the height of a person stands in the center.

There are rows of seats placed all around!

This place is very similar to the auction site outside!

However, because it cannot see the light, it is located deep underground!

Li Longxing quietly opened the Eye of Chaos and discovered that the entire cave was filled with countless strange magic forbidden things.

Once they all explode, they will be powerful enough to trap a strong man in the middle stage of the Demon Emperor’s eighth heaven!

However, Li Longxing was not satisfied with this!

He looked at the Blood Demon Ancestor and asked, "Who arranged the magic ban here?"

Upon hearing this, the Blood Demon Ancestor immediately replied triumphantly. , "This demonic ban was set up by my subordinates together with all the elders and powerful men of the Blood Demon Sect. Master, what do you think? Is the power okay?"

"Well, not bad!" Li Longxing smiled. He nodded and continued to add, "But there is still room for improvement!"

The Blood Demon Ancestor smiled bitterly and said, "The abilities of my subordinates are limited. If I want to improve, it will be difficult. Reaching the sky!"

"I'll do it!" Li Longxing said with a smile, "Do you have the structure diagram of the Demonic Forbidden City here?"

Although he spent some time With time, we can thoroughly study the magic forbidden area in this place!

But if there is a ready-made structure diagram of the magic forbidden area, there is no need to waste time.

"Yes, Master!" The Blood Demon Ancestor nodded, flicked his hand, took out a black jade slip, and handed it to Li Longxing!

Li Longxing took it, and when his spiritual mind entered it, he suddenly understood it!

"Next, I will re-arrange the magic forbidden area here. You can observe carefully from the side. It may be of great help to improve your forbidden skills!" Li Longxing said to the ancestor of the Blood Demon. !

During this period, the Blood Demon Ancestor was also very loyal, so Li Longxing deliberately cultivated him.

“Okay, Master!” The Blood Demon Ancestor was overjoyed when he heard this.

If his master is willing to give him guidance, how could he miss such a God-given opportunity?

As soon as he finished speaking, he stared at Li Longxing with bright eyes, unblinking!

Li Longxing flicked his hand and took out a large number of high-level magic treasures!

These treasures were all collected from the old madman’s possession not long ago.Obtained from the treasure map.

Used to reshape the magic forbidden area here, which can greatly increase the power of the magic forbidden area.

Li Longxing kneaded the techniques with both hands, first tempering the high-level magic treasures one by one.

Immediately afterwards, he waved his right hand.

Those magic treasures immediately flew like flowers scattered by a goddess, escaped into the void around the cave, and disappeared from the ground.

Immediately, Li Longxing raised his hands again, kneaded the formula repeatedly, and kept pointing towards the void!

Seeing Li Longxing’s dazzling pinching techniques, the Blood Demon Ancestor couldn’t help but be amazed.

In order to let the Blood Demon Ancestor see his technique clearly, Li Longxing deliberately slowed down.

It could have been done with only half a stick of incense, but it took him a full stick of incense!

The last point is made!

Boom!

The whole cave suddenly shook violently.

Immediately, simple black magic patterns flew out from the void, forming black light masks, which were superimposed one after another!

Roughly counting, there are a total of eighteen floors!

"This...is this the Eighteen Demonic Forbidden Periods?" Seeing the appearance of the Demonic Imprisonment clearly, the Blood Demon Ancestor's expression changed drastically, and he couldn't help but exclaimed in shock.

Li Longxing smiled and nodded, "This is indeed the Eighteen Demon Sealing Bans, but due to the limitations of materials and terrain, the power of the demon ban I laid is far less than that of the original Demon Lord of Annihilation. It's laid!"

"Then how powerful can this be?" The Blood Demon Ancestor tried
