Get another Heaven and Earth Spiritual Fire first, and it is also convenient to hide the Netherworld Ghost Fire that Zhang Yifeng will get in the future. Nether Fire must never be used in front of outsiders, unless it is to control fire and kill people!

Thinking that there was likely to be a heaven and earth spiritual fire here, Zhang Yifeng immediately began to look carefully in the vicinity. But after searching all the places, I couldn't find a place to store the Heaven and Earth Spiritual Fire.

"That's right, that hidden formation!"

Zhang Yifeng seemed to have ignored the hidden formation of the main hall.

Although the concealment formation in the main hall saved his life, he always felt that this concealment formation was a bit redundant.

Now that Zhang Yifeng understands, there must be something greasy in that hidden formation. The person who set up the Fierce Demon Blood Forge must be trying to hide something. So, could it be the spiritual fire of heaven and earth?

Thinking of this, Zhang Yifeng returned to the stone house, and after taking off the plum blossom jade plate, he returned to the main hall and re-entered the hidden formation.

Zhang Yifeng looked around, the walls were still walls, as if entering the concealment formation was no different from not entering the concealment formation.

But is it possible that the hidden space of the hidden formation is the same as the outside!

Thinking of this, Zhang Yifeng entered the concealment formation and kept advancing until he reached a wall.

This wall is exactly the same as the wall of the main hall, and what Zhang Yifeng wants to determine now is whether this wall is the wall in the hidden formation or the wall outside!

There is a painting painted on the wall, this is a beast with its claws outstretched and pointing at the ground.

Zhang Yifeng studied it carefully, and then stepped on the ground with his foot.

Thundered. The next moment, the stone wall flipped over, and a door was formed.

"It's on."

Zhang Yifeng was a little excited, but he didn't enter the door immediately, but returned the same way, returned to the entrance of the concealment formation, stepped on two points with his feet, and his whole person came out of the concealment formation.

In sight, there were the same walls, but there was no door that suddenly opened.

Sure enough, there is something greasy in the hidden formation. It looks the same as the outside, but it's different.

Zhang Yifeng grinned, and then without the slightest hesitation, he entered the concealment formation and walked into the stone gate.

Behind the stone door, there is also a stone room, which looks less than ten square meters.

There was only one dry skeleton in the stone room, and I don't know who it was or how it died.

Next to the skeleton, a broken scripture book was scattered.

Zhang Yifeng picked it up and took a look, this is a broken sword technique, the power of the sword technique is very great, but Zhang Yifeng didn't pay attention to it at all, any sword technique he knows is more powerful than this sword technique. What he cares about now is where the spiritual fire of heaven and earth is.

Shaking his head, Zhang Yifeng looked at the middle of the stone house, and in the middle of the stone house, there was a faint blue flame. The flames, though dim, emitted terrifying heat.

Seeing this flame, the corners of Zhang Yifeng's mouth finally opened into a smile.

There is indeed a heaven and earth spiritual fire here.

If Zhang Yifeng guessed correctly, this stone house is under the molten pool. The Heaven and Earth Spiritual Fire was surrounded by a formation, and the heat emitted was directly transferred to the molten pool.

Zhang Yifeng carefully looked at the spiritual fire, and determined that this was the fifty-eighth Blue Moon Fire in the Heaven and Earth Spiritual Fire, and the flame was burning, like a round of crescent moon. It's not a very high level, but it's not low either. For the current Zhang Yifeng, it is just right, and now he can only collect this level of heaven and earth spiritual fire.

It's just that Zhang Yifeng was a little puzzled, the color of this blue moon fire seemed to be a little dim, giving Zhang Yifeng a feeling that it would dissipate again in heaven and earth when he blew a breath.

"Take it."

Shaking his head, Zhang Yifeng locked his mind onto the Blue Moon Fire, intending to take away this spiritual fire.

But Zhang Yifeng found that he couldn't break through the formation around the Blue Moon Fire at all.

Zhang Yifeng tried to attack the formation, his body instantly flew upside down, a mouthful of blood spurted out of his mouth, and even, he couldn't stand up for a while.

Strong!

The protective formations around these four also contain attacks.

Zhang Yifeng's pupils contracted, trying to calm himself down, he felt that things were not as simple as they seemed.

Zhang Yifeng looked up at the dry bone in the middle of the stone room, this person was definitely not the owner of the ruins, maybe he was also a formation master, he had entered here a long time ago and found the hidden formation.

Could it be that he was killed in the process of breaking the ban?

Thinking of this, Zhang Yifeng's body shook violently.

This prohibition can kill people!

His current cultivation is too weak, and he doesn't understand the formation, which means that it is difficult for him to get the "Blue Moon Fire".

Zhang Yifeng's face was ugly, he was very entangled now, there were obviously good things in front of him, but he couldn't get it, he turned around and left, but he was unwilling.

"That's right, Tianjizi!"

Suddenly, Zhang Yifeng patted his head, he had just gotten the Tianjizi, although it was broken, but maybe it could help?

As soon as he thought of it, Zhang Yifeng hurriedly took out the Tianjizi and began to watch the content on the Tianjizi.

Just after looking at it for a while, Zhang Yifeng's whole body trembled. Although this Tianjizi is a fragment, it is just the beginning of Tianjizi. It clearly records and explains what a formation is.

The formation is a kind of magic power that attracts the power of heaven and earth with the formation pattern!

So, what is a pattern? The formation pattern is like a human skeleton, except that it communicates with heaven and earth, not the human body.

The amount of information in Tianjizi is very huge, and it is also very shocking.

Tianjizi said that a powerful space formation can move mountains and reclaim the sea, turning the world upside down.

Tianjizi said that a powerful killing array slaughtering a world is like slaughtering chickens and dogs.

Tianjizi said that the powerful phantom array can make people live forever and cannot escape, until they can't bear the eternal loneliness and commit suicide by themselves.

Tianjizi also said that the powerful time formation can speed up time, and the head will be white overnight.

Even, Tianjizi also said that there are some formations that can deduce the future and predict good luck. This type of formation is called an anomaly. It's a pity that what Zhang Yifeng got was only the formation chapter, and it was still a fragment.

This volume of Tianjizi recorded some formation techniques and formation breaking techniques, most of which were formation breaking techniques of odd formations, and the Twelve Beast Emperor Formations were among them.

If it was a young man who got the heavenly machine, he might think that this book was bragging, but Zhang Yifeng knew that these were all facts, and a powerful array master did have the power to destroy the world. Of course, the formation that can destroy the world has long been lost.

Zhang Yifeng took a closer look, then sat cross-legged and began to study the formation and set it up.

Formation, it's hard to say, but if you have a textbook in front of you, as long as you have talent, it's not so difficult to learn. As for how far you can go, it depends on how demonic your talent is.

Zhang Yifeng tried to calm himself down, and began to carve the lines according to the formation technique that Tianjizi said.

Heaven and earth have lines, you have to be sensitive, and what you need is talent.
