Meng Nan walked over to the skeleton that was sitting cross-legged under the stone pillar and found that on the ring finger of her right hand, she was wearing a quaint ring.

"Could it be the Void Ring?" Meng Nan thought.

He thought for a moment, bowed down to the skeleton and solemnly saluted with the etiquette of a warrior, and said, "Senior, offended!" As he spoke, he bent down and took the ring from the skeleton, and at the same time, a wisp of divine consciousness poked out of his spirit and fell on the ring.

Sure enough, it was a Naxu Ring, and the space inside was more than ten times larger than the low-grade Naxu Ring in his hand, and it was a high-grade Naxu Ring!

However, although there is a large space for this void ring, there is nothing in it.

In addition to a pile of women's clothes, there were only dozens of books and piles of formation materials and other things left, Meng Nan rummaged through the few items in the Naxu Ring, and suddenly, he found a letter, and his heart moved, and the letter appeared in his hand.

Looking at it intently, what appeared in front of him was a handsome handwriting.

Meng Nan quickly read the letter and let out a long breath.

This letter is the last pen of the skeleton in front of him, and Meng Nan knew her origin from the letter.

It turned out that the skeleton in front of him was actually a king-level martial artist before his death, and he was only half a step away from breaking through and surpassing the king-level, but unfortunately he fell here. Not only that, but this woman is also a formation master.

A thousand years ago, some of the warriors who hated the insect demons in the human race united to fight back against the underground world, and the woman in front of them was one of them.

The warriors who invaded the underground world slaughtered in the underground world, and countless insects and demons died in their hands, and because of this, they aroused the hatred of the underground insects and demons, and were hunted down and encircled by a large number of insects and demons. In the face of the seemingly endless insect demons, none of these warriors flinched, they fought and retreated, and finally, the army of 100,000 insect demons that surrounded and suppressed them was led to this place.

Everyone died in battle, only this woman who had been ambushed here for a long time to set up a killing array, seeing her companions die in battle, the woman was inexplicably sad and indignant, and resolutely used her own life as a guide to stimulate all the power of this Nine Dragons Heaven Sealing Killing Array that she couldn't control.

The big array trapped the 100,000 insect demons who came after him, and trapped them in the formation one by one, and the woman also fell because of the counterattack of the formation.

Before the woman died, her strong obsession made her decide to give up the hope of reincarnation, directly ignite the spirit, turn into an immortal will, integrate into the Nine Dragons Heaven Sealing Array, and continue to control the operation of the formation.

"Human intrusion can give birth to ......"

"The worm demon clan, all of them should be damned!"

"Kill all those disgusting bugs!"

These are the last consciousnesses of the woman left in that wisp of immortal will.

At this time, the little girl in green also walked up to Meng Nan and looked at him curiously.

Meng Nan glanced at the little girl who was carved in pink and jade.

If he guessed correctly, this little girl is not human.

She should be the last will of the female senior who laid down this great array, and the array spirit was born after nearly a thousand years in this peerless killing array!

"Little sister, are you the spirit of this Nine Dragons Heaven Sealing Array?" Meng Nan asked.

The little girl nodded innocently and said with a smile: "Yes, everything here must listen to me!"

Sure enough, Meng Nan secretly rejoiced in his heart, fortunately, in the will left by this female senior, she also subconsciously left a way for the human warrior to live, otherwise he would have been miserable. A terrifying killing array that can trap and kill 100,000 insects and demons, how can he resist it?

Meng Nan put away the letter in his hand, looked at the skeleton of the woman in front of him and bowed deeply, and his heart was full of respect for this unknown female senior.

He turned around and took a deep look at the little girl, Array Spirit?

"Then little sister, can you give me some of these flowers?" Meng Nan asked, pointing to the blood flowers all over the ground.

"Of course you can!" The little girl waved her hand nonchalantly, and saw dozens of ghost blood flowers uprooted from the ground and flew in front of Meng Nan out of thin air.

"Is it enough?" said the little girl.

"Enough is enough, thank you little sister!" Meng Nan laughed and said repeatedly.

Now the last mission can be completed, and the next step is to leave here and bring the Bloodflower back to the academy.

"Big brother," the little girl suddenly cried out.

"Hmm, what's wrong?" Meng Nan asked.

"Can you take me out of here?" the little girl looked at him with wide eyes, a look of hope.

"Leave?" Meng Nan was stunned for a moment, "Don't you like it here?"

"I don't like it. The little girl pursed her mouth, "No one is playing with me, big brother, will you take me away?"

The little girl said, looking at him pitifully.

Meng Nan almost didn't think about it, and nodded.

Not to mention that the little girl's pitiful appearance made him reluctant to refuse at all, let's just say that the array spirit itself is a rare creation!

Among all the spirit bodies, the spirit of the spirit weapon is the most common, in addition to all kinds of heaven and earth spirit objects, as long as the opportunity is right, they will also transform into spirits, but the array spirit is the rarest.

The formation is originally a dead thing, and it can only be formed by people to arrange, and after it is arranged, it is necessary to rely on people to control it, and once most formations are laid out, the power has been fixed. This is the most difficult situation to give birth to spirits, which is too dependent on human power and has no room for growth.

However, the rarer it is, the rarer it is.

Once the formation spirit is born, it is no longer bound by the original formation, and from then on it becomes a new life entity with unlimited potential. Because the formation spirit is born with the talent of controlling the formation, no matter what the formation, as long as it is given time, it can learn, as long as there are enough materials, it can be arranged and can be perfectly controlled.

Imagine that being able to get a formation spirit to follow is equivalent to bringing a formation master with unlimited potential, the future formation master.

This kind of business that only takes advantage of advantages and does not suffer losses, it is strange that Meng Nan does not do it.

"Okay, then I'll get you out of here. Meng Nan said with a smile.

"Great!" the little girl jumped up in surprise, cheered and pounced on Meng Nan, clicked, and kissed him on the face, "Big brother, you are really a good person!"

"Haha!" Meng Nan laughed, he didn't think anything about receiving a good guy card inadvertently, what's wrong with a good guy, if there is such a benefit every time, he doesn't mind being a good guy a few more times.

"Little sister, what's your name?" Meng Nan asked again.

"I ...... I don't have a name. The little girl looked depressed.

"No name...... Then I'll call you Xiaoying in the future, okay?"

"Little Shadow...... Okay, I'll be called Xiaoying from now on! I'm so happy, I have a name......

Meng Nan looked at the innocent and cute little girl and couldn't help laughing.

It's time to leave.

I didn't expect to be chased and killed by that nasty demon butterfly for three days, and I was able to meet a rare array spirit in the world, and they all said that blessings and misfortunes depend on each other, which is really reasonable. Thinking of the Demon Butterfly, Meng Nan was stunned for a moment, and somehow, the latter's murderous appearance of not killing himself and swearing not to give up suddenly flashed in his mind, and a thought popped up in his heart: That guy won't be gone yet, right?

He thought for a moment and said, "Xiaoying, can you see the situation outside the formation." ”

Xiaoying raised her flushed face and said, "It's okay, but I can't see too far." ”

"Okay, you can help my brother take a look, is there a big butterfly outside in the direction my brother came from just now?"

"Big butterfly?" Xiaoying was slightly stunned, tilted her head as if thinking about what a big butterfly was, and suddenly she seemed to have found something, and shouted: "Big brother, there is a worm demon outside, do you see if it is the big butterfly you said?"

As soon as she beckoned, the white mist blocking Meng Nan's vision suddenly disappeared, and when he looked at it, his heart suddenly felt slightly cold.

But when I saw that demon butterfly, it was still outside this big array, about three feet away.

A pair of huge wings enveloped her entire body, as if she was undergoing some kind of metamorphosis.
