"It's been boring for so long, how could I give up such an opportunity, this time I'm going to cultivate this guy into my inner pill spirit, not only to pass the time but also to improve my own strength. Said with a smiling smile.

"Na Lan Lin, what is this Neidan spirit?" I asked, confused.

"It's very simple, it's the Inner Dan Spirit. Na Lan Lin said.

"In that case, a dying person was also trained into a spirit soul by a high-level spirit beast?" I asked suspiciously.

"Not exactly, the spirit can be naturally condensed from the inside, or it can be condensed from the outside. It is naturally formed, but there are not many races of spirit beasts that have such unique conditions. Although the bloodline purity of the Silver Scale Jiaoyu clan is very high, and it is the top bloodline spirit beast of the water element, it cannot naturally condense into a second inner pill, and if it wants to condense into an inner pill essence soul, it can only be refined externally. Na Lan Lin said.

"And does he still have his own thoughts?" I asked, thinking for a moment.

"Of course...... Without...... But it's still much stronger than dying now, when he is refined into an inner pill spirit by me, both his and my strength will be greatly improved, why not ...... it," said with a sparkling smile.

"So be it. I said lightly.

"You can go on, but I don't think you can break into the main hall. Even if you enter the main hall alive, I don't think you can come out alive, and it may be too late for you to turn back now. Said with a smiling smile.

"Senior Water Emperor, there is one more thing to tell you...... "I just used my soul power to probe and found that there was a big battle on the side of the Earth Emperor Palace, and the powerful soul clan master was killed by Huyan Moxi and them together. However, all the men brought by Huyan Moxi were sacrificed because of this, and Huyan Moxi, who was seriously injured, walked towards the Water Emperor Palace alone.

"Looks. I'm going to refine him into a Neidan spirit as soon as possible......" Xuan Yan said after thinking about it.

"If you have any trouble, you can come to me. I said with a smile.

After handing over this big trouble to the Water Emperor, our group continued to walk to the depths of the underground palace, according to the structure of the underground palace, we broke through the Water Emperor Palace, and we were not far from the main hall of the underground palace. But we walked for a long time, and I found that my soul power could extend back to the Fire Emperor Hall in terms of the length of a straight line, but I couldn't find an exit. I don't know how long it took to walk, but even Xiao Hei and the Ghost King couldn't hold it anymore, so we decided to rest in place and continue walking......

"Master, I think we may have walked into some formation again. Na Lan Lin said.

"Did you find anything?" I asked, confused.

"No, but do you think this tunnel is a bit too long? This underground palace only covers the entire underground of Xuanyu City and the suburbs, but we have been walking for nearly two days, and under normal circumstances, it is enough to walk around Xuanyu City for several days. If it's a formation, we have to find a way to find it or destroy it, otherwise I'm afraid it will keep going. Na Lan Lin said.

"Ghost King. Can you see what formation is here?" I asked, turning my head.

"I can't see it, it's already very difficult to maintain my human form now, so how can I pay attention to any formations. The little boy said angrily.

"Let's try a little longer. I said helplessly.

The consequence of continuing to walk in was that after I didn't know how long, I realized that I couldn't find anything in my current position, and I couldn't find anything in the back and forth with my soul power, that is, we were completely trapped in this damn tunnel.

"It can't be helped. "I took out the last red brocade box and opened it, there was a golden key carved with a totem, and there was not even a manual for the others, how did I know what to do with this broken key.

"Master, what's the use of this key?" asked Na Lanlin suspiciously.

"Hehe, I want to ask you. You're still asking me!" said angrily.

"What is this?" Sikong Shu asked with a puzzled look when she saw me take out a key.

"Ghost King, do you know what this is?" I asked with a bitter face.

"How would I know. The little boy said coldly.

"I know. Gou Chen said suddenly.

"You...... You know, how do you know, what is this?" I asked, confused.

"This thing is called Toru Tenki, and it was made by the owner and one of his friends, and I have seen it a few times so I remember. I remember that my master said that this heavenly machine can open all the mechanisms and formations in the world. Gou Chen said.

"Can you open all the mechanisms and formations in the world?" I said in shock, looking at the golden key in my hand.

"That's what I said. But I've never seen my master, and he's used it. It seems that after it was manufactured, I only saw it a few times, and it was just a matter of taking it out and looking at it when the owner sorted out the items. So I don't know if it's useful or not. And it's very strange that I haven't seen this strange thing since the master's death, how can it be in your hands?" Gou Chen also looked puzzled.

"How could this be in the hands of the prophet?" I asked, confused.

"Maybe she knew the owner of the tomb. Na Lanlin said lightly.

"Anyway. The fact that the prophet actually gave me this thing means that I must use it, and I think that this heavenly machine was made by the owner of the tomb himself after all. Even if he can't unravel all the formations in the world, the formations he has arranged by himself will definitely be able to open. I said with a smile.

"You mean this thing can open this formation?" Sikong Shu leaned over and asked curiously.

"It should work. I said, playing with the key in my hand.

"But how do you use this thing?" asked Sikong Shu suspiciously.

I was also stunned for a moment, it didn't look like opening the door when I broke the formation, and there was no keyhole for me to plug in. I spun around the same place for a long time, and I didn't know where the hell this key was going to go......

"Since it is a broken formation, it should be inserted into the eye of the formation. Na Lan Lin said.

"Array Eye, what are you kidding, if I can find Array Eye, I'll still need this broken key!" I said angrily.

"Since the key is made, there must not be such a complicated operation, otherwise if you want to find the structure and find the formation eye first, then there is no need for this key at all, I think it is okay to follow the rhythm of the use of the general magic weapon. You just inject soul power, and then stick it wherever you want, and it should be able to find the formation eye on its own. Gou Chen said.

"Is it that simple?" I asked, incredulous.

"You can try. Gou Chen said.

"Try it, try it. "I mobilized my soul power and injected it into the golden key, and then forcefully thrust it into the ground, and then the golden energy spread out like a network of leaf veins, and soon a red ball of light rose up.

"Looks like that's the eye. Na Lan Lin said.

I inserted the key into the ball of light and spun around, then I heard a loud noise, and I once again emitted my soul power, and found that it was only about three hundred meters away from the exit. We walked out after walking for a while, and I found that this heavenly machine is really a magic weapon, not to mention the outside, it can be said that it is a general artifact in this underground palace.

"With this thing, we are not afraid of anything. Sikong Shu said with a smile.

"Not necessarily......" I said with a wry smile as I looked around.

Although it was my first time in this place, it always felt familiar, it was like an enlarged version of the Colosseum, full of broken blades and bones, and a chilling murderous aura......

"What the hell is this place?" asked Sikong Shu.

"This is specially built by the master to select his henchmen. Gou Chen said.

"How to choose? Is it to raise a large number of spirit beasts and then lock them up here to fight each other, and then the ones who survive are the henchmen, this seems to be the only thing that slave owners do. I said depressedly.

"That's right, that's how the Five Emperors were chosen. Gou Chen said.

"What about you?" I asked curiously.

"I'm a spirit pet. Gou Chen said angrily.

"Is there any point in building this thing in the crypt dungeon?" I asked, confused.

"Absolutely. Suddenly, a figure appeared in the middle of the venue, this was a young man who looked to be in his twenties, he was wearing a black cloak with a hood, and he was a bit like the Great Elder of the Moying Hall, but it was obviously much younger than him.

"Are you?" I asked, confused.

"The deity is called Puppet Xiang, and he is ordered by his master to manage this place. The young man's cold voice seemed to come from hell.

"What does His Holiness want?" I asked faintly.

"You have to fight, and only half of them can go on. There are six of you on your side, which means that only three of you can leave here in the end and continue down......" said Golem.

"So as long as there are three people left, you can get out of here?" I said, stunned for a moment. (To be continued......)
