After coming out of the cave, a square of tens of thousands of square meters appeared in Ning Xin's sight, and what attracted her attention the most was the immortal tree in the middle of the square that was about ten meters high, without any branches around it, and was covered in bright red.

At this time, there was a black group exuding a powerful aura in the four directions of the square, southeast, northwest and northwest, and the demonic qi in the square was constantly gathering in their direction, and the four black groups were getting bigger and bigger, and more and more condensed.

"Ning Xin, those four black groups are the demon spirits guarding the undead tree, you must get the wood spirit fire in the center of the undead tree before they wake up. If they wake up, you won't have a chance, and with your current cultivation, you're definitely no match for them. ”

"I'll hurry. ”

Although time was pressing, Ning Xin still carefully explored the entire square, except for the four demon spirits, there was no other danger here.

However, Ning Xin frowned and looked at this huge square, and did not venture into it, she felt that in addition to the demon spirit, the ancient demon venerable should have other ways to protect the immortal tree in the center of the square.

Although the square seemed calm and unwavering, it always gave her a strange feeling. Ning Xin used her divine sense to probe, but she didn't find any traces of the formation, what was wrong?

After thinking about it, Ning Xin threw a dead demon beast in the space into the square, and after a few breaths, there was silence in the square, nothing happened, Ning Xin had some doubts in her heart, could it really be that she thought too much?

After that, Ning Xin threw a few more demon beasts in, but nothing happened in the square, Ning Xin looked at the black groups that were getting more and more condensed, and decided to go into the square to have a look.

When one of her feet just stepped into the square, a trace of silver light flashed quickly at the edge of the square, and Ning Xin's heart beat sharply.

In an instant, Ning Xin retracted her feet, this panicked feeling would only appear when she was about to encounter a danger to her life, there must be something strange in this square. Ning Xin used her divine sense to explore the square back and forth a few times, but still didn't find anything wrong.

After thinking about it, Ning Xin sent out a spiritual attack towards the square, but there was no response, and after that, she sent out a spiritual attack on the square, and the soul power disappeared without a trace as soon as it reached the sky above the square.

"This square can absorb soul power!" Ning Xin said with some surprise, and then looked at the unscathed demon beasts in the square, and then took out a live ink soul fish from the space and threw it into the square.

As soon as the cuttlefish entered the square, the silver light flashed around the square in a few breaths, and countless gray-white array flags appeared in the square, and the cuttlefish was not dead, but at this time, Ning Xin's face was very pale.

When she threw the cuttlefish into the square, she left a divine sense on the cuttlefish, and although the cuttlefish was not dead now, it was sucked away the moment it entered the square.

"Ning Xin, there is a soul pumping array arranged in this square! Seeing the cuttlefish in the square, Xiaobai said anxiously.

"I know!" Ning Xin held down her rapidly beating heart and exhaled a long breath, fortunately she had withdrawn her step in time just now, otherwise she would have only been left with a soulless body now.

After calming down, Ning Xin began to think about how to crack this long-lost soul extraction array.

As the name suggests, the soul drawing array is to drain the soul of the living creatures that enter the formation, and completely destroy the soul that is extracted, dissipating in the heaven and earth, and all monks or demon beasts who have been extracted by the soul drawing array have no chance to enter reincarnation.

This formation can be described as insidious and poisonous, a long time ago, those monks who could arrange this formation were jointly strangled by other monks, and the soul extraction array slowly disappeared into the long river of history.

Looking at the dozens of flags flashing out of the square, Ning Xin was a little strange, "Why do I think this flag is so familiar?"

When she saw the silver light flowing on the flag, Ning Xin suddenly remembered, "I seem to have one such flag in my hand." As he spoke, he searched for the bracelet, and after a while he had the same flag in his hand as in the square.

This flag was exchanged between her and a Avatar Monk at the Underground Exchange of Heavenly Flame City.

Ning Xin compared back and forth several times, "It's the same, Xiaobai, do you think this flag was originally on this square?"

"It should be possible. ”

"There are eighty flags in this square, and according to the law of arrangement, there should be ninety-nine and eighty-one flags, that is to say, the flag in my hand should be on this square. Then this soul pumping array is not complete. ”

"It should be like this, otherwise you wouldn't have been able to get out of the square when you stepped into the square before. ”

"Hearing you say that, it seems to be really like this! I've only heard of this soul extraction array before, and I don't know anything about the others, how can I break this formation? Hey, this soul extraction array is a flag array, I will draw out all the flags here, this array will not be able to maintain, this can be regarded as a broken formation!"

"Eh, although I don't know the formation, I still know some basic common sense, can you remove the formation flag from a formation?

"Hmph, if it's a complete formation, I naturally can't do it, but this incomplete formation can still be tried. But first I have to find the location of the flag I have in my hand. ”

"I warn you, there's not much time left, those four demons are not far from waking up!"

"I know, if I don't break this formation, I won't be able to get in!"

Ning Xin quickly ran around the square, her divine sense was highly focused on each flag, and she kept calculating the magic trick in her hand, and only after an hour did she find the location of the flag in her hand in the square.

After that, Ning Xin took that position as the center, transported the five-line duel, and continuously output the spiritual power, and the spiritual power quickly transformed into five spiritual powers in the air, like a water snake, they attacked the root of the flagpoles of the five flags respectively, and each spiritual power was attached to a divine sense.

After the spiritual power wrapped around the flag, Ning Xin quickly tightened the spiritual power and launched a divine sense attack, slowly pulling up the flag, Xiaobai looked at Ning Xin, who was constantly outputting spiritual energy, and pinched a cold sweat for her in his heart. But when it saw that she had really pulled out the five flags, Xiaobai was so surprised that her mouth widened.

At the beginning, Ning Xin needed to spend a lot of spiritual power, divine sense, and time, but the later it was, because the formation was greatly damaged, the easier it was for the banner to be pulled up.

In this way, Ning Xin spent nearly three days pulling out all eighty flags.

Looking at the bare square, Ning Xin smiled knowingly, no matter what kind of formation was arranged, the formation mage had to use the divine sense when setting up the formation, she just used her divine sense to erase the divine consciousness on each banner, and then used the spiritual power, so that it would not be too difficult for the banner to be pulled out.

However, this method is not suitable for every formation, and it is not possible to use complete formations and formations that consume divine consciousness and spiritual power.

After the flag was pulled, Ning Xin quickly collected the flag, and then threw a cuttlefish into the square, and only after finding that the cuttlefish did not move any abnormally, Ning Xin stepped into the square.

At this time, Ning Xin's state was not very good, her divine sense had been consumed by seven layers, and her aura had recovered to eight layers after taking the Hui Ling Pill. However, seeing the increasingly condensed demon spirit, Ning Xin quickly ran towards the immortal tree.
