But at this time, Ning Xiaotian didn't have time to think about this, because the little Xuannu seal he used had already taken shape, and he was about to smash it towards the bronze ancient coffin!

Rumble!

A violent explosion was transmitted to all corners of the cave in the next second.

Even every speck of dust trembled violently at that moment!

Of course, the bronze coffin that was hit trembled even more, as if it was about to burst open at any time.

However, it was only a moment later, and the entire cave returned to normal, and the bronze ancient coffin did not have a crack caused by Ning Xiaotian's burst Little Xuannu Seal, but it calmed down immediately after the violent tremor.

However, even so, Ning Xiaotian couldn't help but be shocked in the depths of his heart.

"I really didn't expect my strength to really improve."

Ning Xiaotian looked at his hands and looked at his entire body, and his heart was a little shocked, if he used the Little Xuannu Seal according to his previous strength, let alone produce such a riot, it would stop immediately with just one blow.

How could it have such an earth-shattering effect?

Although he realized the improvement of his strength, Ning Xiaotian was very puzzled in his heart, did he do something?

I don't seem to have encountered any monsters that can train and improve my strength, so what's going on?

"Isn't it?"

Hiss –

Ning Xiaotian suddenly remembered something, could it be that those before were really hallucinations?

"Hallucinations until you go to bed? Perhaps, I am just the first time in this cave, maybe there is no stone statue at all, maybe there are no mummies at all, maybe ...... There is no such pattern at all! ”

Ning Xiaotian's pupils shrank suddenly, and for some reason, so many incredible thoughts appeared in his head at this moment.

"How is that possible?"

Ning Xiaotian smiled bitterly and shook his head, "If all this is fake, then how can I still be aware of the bronze ancient coffin here, as well as the ...... in my head?"

Just thinking about the previous times when he had encountered the same underground tombs, Ning Xiaotian suddenly found that the front and back were completely closed at this time, and there was no passage to the underground tombs at all.

"Huh? What's going on? Why is there no passage here? ”

Ning Xiaotian frowned a little and walked to the door of the passages that he had shuttled before, there should have been a hole here, but at this moment, there was nothing, no, there was, it was just a hole wall that was no different from everywhere.

Seeing the scene in front of him, Ning Xiaotian suddenly felt that his brain was not enough, it was the first time he had seen such a strange thing.

No, it was the first time, he had seen it many times before that sleep!

What's the use of hallucinating now?

Ning Xiaotian sneered, and then stared at the book.

"The only clue that can get me out now is probably what is recorded in this book, but ...... This is not necessarily true either. But no matter how you follow the content of this book, you need to give it a try, otherwise, there is really no chance. ”

Ning Xiaotian thought for a moment, and immediately prepared to think about how to open this bronze ancient coffin.

"At present, with my own strength, it is obviously not good, even with the help of the little Xuannu seal, the effect is very small, attack, it may tremble once, it may tremble twice, maybe attack ten times It can produce an unexpected and surprising effect, but this little Xuannu seal is too consuming aura, let alone ten times, five times I can't bear it!"

Shaking his head, at this time, Ning Xiaotian suddenly remembered that he had a very important thing on his body.

That's the demon beast Neidan!

Ning Xiaotian thought for a moment, and quickly took out the three demon beast Neidan that he had taken from the death worm before.

It's not crystal clear, but there is a strong aura up and down the golden eyes.

And in addition to the aura, there is also a faint aura that makes Ning Xiaotian indescribable but extremely tempting!

"This breath ......"

Ning Xiaotian couldn't help but be curious, the corner of his nose was slightly moved to the palm of his hand and sniffed, but just like that, just for a moment, Ning Xiaotian felt a cool breath rush over, and his whole body was suddenly extremely refreshing, and his body seemed to be washed by an inexplicable air current, which was very refreshing!

Especially the Nine Dragons True Qi in his body, it seems to have been induced by this breath, and it is constantly stirring in his body, and even the aura consumed by casting the Little Xuannu Seal before has been greatly replenished at this time.

The aura contained in that demon beast's inner pill seemed to be more abundant than his own spirit stone!

Looking at these three strange things, it can be said that Ning Xiaotian is the biggest surprise at the moment.

"Before, it was said that a hundred monsters in the secret realm were killed, and then each person must hold at least five demon beast inner pills before they can open the portal in front of the tavern and send them to the next layer, this is a hard condition for teleportation, it seems that this demon beast inner pill is indeed powerful! I just don't know if this thing can be eaten? What happens when you eat it? ”

Ning Xiaotian thought in his heart.

The Demon Beast Neidan can be said to be the essence of every monster, and the reason why they can be so domineering and arrogant in the desert or other places depends largely on these Demon Beast Neidan.

Once they lose the demon beast Neidan in their bodies, it can be said that the strength of those monsters is greatly reduced, and it is not too much to say that they have lost two-thirds of their strength, or even more.

This is the power of the demon beast Neidan, the essence of the demon beast!

Ning Xiaotian naturally knew a little about these, and it was also because he understood their power, so he didn't dare to take them rashly, if he relied on his previous temperament, the genius treasure of this essence would have already been swallowed!

That is definitely a rapid improvement for improving one's own strength!

"But ......"

But now Ning Xiaotian looked at the three demon beast inner pills in his palm, and he really had a feeling that he could only watch from a distance and not play with them, and the ghost knew what consequences these three pills would have on himself if he ate them!

In case of any accidents, then I really have no chance to turn over!

After thinking about it for a while, Ning Xiaotian still hesitated and took it back into his pocket.

The bronze ancient coffin began to spin around, and while turning, Ning Xiaotian secretly thought about how to pry it open and then not spend too much of his true qi power.

But in this way of getting the best of both worlds, Ning Xiaotian finally gave up after about fifty circles around the bronze ancient coffin!

Nima, how can you pry such a sturdy thing!

I'm not the physicist Archimedes who gave me a fulcrum, what physicist I could pry up an earth.

Ning Xiaotian shook his head: "Come on, I'm still like some realistic ideas!" ”

"Realistic ideas...... Where is this Nima going to find some realistic ideas! Or ......"

After hesitating several times, Ning Xiaotian finally took out the three demon beast inner pills and came out.

"Is it okay to eat this thing, if you don't swallow it, you just die violently." Ning Xiaotian was depressed, but after thinking about it, he said, "Uh...... But if you don't swallow it, there seems to be no other way, his grandmother's, if it is a death horizontally and vertically, Nima might as well die a little stronger! ”

"Eat!"

Ning Xiaotian seemed to be greatly stimulated for a moment, and immediately broke one of the demon beast inner pills in half, and then took a piece of it and put it in his mouth after hesitating for a long time.

"Bitter! Nima, what a bitterness! ”

Ning Xiaotian couldn't help but scold, feeling like he had eaten...... It's the same, it's a mouthful of bitterness!

Half a piece!

He's only half of it, uh...... It's not that he's cowardly, in fact, even if he swallows all three, there's no problem, it's just that he's ...... It feels like that's a bit of a waste, well, a waste.

After swallowing the half of the demon beast Neidan into it, Ning Xiaotian was surprised to find that nothing had happened, what is the legendary side, the breath in his body was constantly surging, and even the outside of his body was filled with streams of essence......

Uh, well, none of that!

Nima, Daddy! Ning Xiaotian scolded directly.

It took thirty-seven twenty-one to convince myself to swallow this half of the seed, and at this time there was not even a hair!

Ning Xiaotian was really drunk, so he simply didn't want to think about it so much, so he just swallowed the remaining half of it at once.

"It's really bitter...... Ning Xiaotian scolded: "If I knew this, I would never eat it, it's really bitter......

Just as he was complaining, suddenly a powerful force came directly from all over his body, hitting the dantian!

That kind of intense pain spread all over his body, and Ning Xiaotian didn't expect this kind of thing to happen suddenly.

This situation was also too abrupt, and Ning Xiaotian's legs were so weak that he collapsed directly to the ground.

If the other two demon beast inner pills in his hand hadn't been held by Ning Xiaotian with all his might, it is estimated that he would not know which corner they had fallen into now.

"Ahh

Ning Xiaotian lay on the ground in great pain, his whole body seemed to be twitching, and the kind of heart-piercing and indescribable pain made him extremely uncomfortable.

Can't even speak!

This pain is not the direct pain of an organ in the body, but a sharp swelling pain everywhere, every skin, every flesh, and even every blood!

Ning Xiaotian didn't expect it to be the result in front of him.

The nerves twitched little by little, although Ning Xiaotian's eyes were open, his brain was almost blank, if it wasn't for the fact that there was no white foam coming out of his mouth at this moment, otherwise others would definitely think that he was poisoned when they saw his scene at the moment!

Of course, he seems to be poisoned in that situation now!

Ten minutes!

Half an hour!

An hour!

……

That kind of pain not only did not weaken, but also kept intensifying, making Ning Xiaotian completely unable to speak, in a state of extreme struggle.

In the end, I don't know when, there was another intense pain, which made Ning Xiaotian faint directly!
