After Fang He walked about a hundred steps along the previous flashing position, the empty underground space suddenly became a little unusual, the originally stable space suddenly became vibrating, and then, the surrounding aura also became violent.

As the spatial vibration and aura rage intensified, stones began to fall from the top of the unknown height, and it seemed that this space was now gradually collapsing, and without thinking too much, Fang He suddenly sped up.

When the space behind him completely collapsed, Fang He also walked to the end of this space, a stone door more than one person high was inlaid in the rock, and it was pushed open with a gentle push, and what came into view was also an open stone room, a huge crystal coffin was placed in the middle of the stone room, and there were night pearls of various sizes surrounding the top of the stone room, emitting bursts of light, and the beam of light that Fang He sensed before was emitted by these night pearls.

Against the backdrop of the pitch-black cave roof, this stone chamber is also as beautiful as the starry sky, but it is very different from the starry sky in the Sword Valley, the starry sky in the Sword Valley is not substantial, everything here can be touched, look closely, the trajectory of these stars is the same as that of the Sword Valley, and it is exactly the same as the trajectory of the stars in the outside world; Such a scene made Fang He surprised again and again, who would have thought that there was an ancient tomb hidden under this underground.

Out of curiosity, Fang He walked gently towards the crystal coffin, with a little apprehension in his heart; After approaching, under the light of the roof of the cave, the relief statue on the coffin was like coming to life, and it looked lifelike, which also made Fang He's surprise in his heart deeper, and he couldn't help but stop and watch.

This kind of observation is not only to watch, but mainly to probe whether there is any danger hidden in the shadows; Maybe this place is secret enough, and there is the ice and fire world and those unknown ores barrier, there is no danger here, Fang He simply put his hands on the coffin lid, and pushed it away with a light push.

The moment the lid of the coffin was opened, there was a strong burst of brilliance in the coffin, after adapting to this strong light, Fang He looked at it fixedly, only to see that there were countless spirit stones densely stacked in this coffin, and its quality was much better than the so-called best spirit stones in the outside world, as for why it was so sure, it was because many of the things that Yun Zi gave him at the beginning were also the best spirit stones.

"It's gone!" This was Fang He's only thought at this time, so he used both hands and feet to receive all these spirit stones into the Void Spirit Ring.

Gradually, he found something wrong, if you look at it by volume, Fang He has already collected all the spirit stones in the coffin, but this is not the case, with Fang He's continuous collection, the situation at the bottom of the coffin is slowly revealed.

It turns out that this coffin was not placed here, but part of this stone chamber, and there is still a lot of space at the bottom of the coffin; After continuing to collect for about an hour, Fang He collected all these spirit stones, at least hundreds of millions of fast, this is only a conservative estimate, if you count carefully, the number will only be more than this number, and it can almost cover the Taoyuan Valley in the Sword Valley.

This is undoubtedly a huge amount of money, during this period, Fang He also tried to absorb a spirit stone, its effect is almost more than a hundred times that of the best spirit stone, and the absorption speed is also much faster than the best spirit stone, on the whole, a piece of this spirit stone can be exchanged for a hundred top grade spirit stones in the same amount.

If Fang He can get out of the underground smoothly, in terms of wealth alone, there is no one in this world who can compare with him. Of course, such a huge amount of wealth, Fang He would not be exposed, and even before his cultivation broke through to the Holy Realm, he would not dare to use it easily, after all, the best spirit stone was already a rare cultivation thing even for the powerhouses of the Holy Realm.

After collecting these spirit stones, Fang He also came to the space at the bottom of the coffin, and after looking around, he didn't find the imaginary corpse, only an ancient box was placed randomly in a corner, maybe it was too long to exist, Fang He just touched it lightly, and the box turned into ashes.

Fan off the dust, a notebook appeared in front of Fang He's eyes, there were three big characters on the cover, but the font was very different from the current world, but fortunately, Fang He read a lot of ancient books when he was a child, and he just recognized this font.

These three words translate to the Imperial Spirit Technique, which made Fang He's heart start beating wildly.

In the ancient books he had read and the perceptions of the senior monks in the Demon Valley, there was a sporadic introduction of this exercise, the origin of this exercise can no longer be traced, perhaps it may have been born on the occasion of the opening of the heavens, and its biggest role is to control all spirits, and the so-called spiritual path, royal path and many other avenues are also derived on the basis of this exercise.

Carefully picked up this notebook, although it was a little obscure, Fang He still worked hard to translate it all, so as to obtain a complete Imperial Spirit Formula, this "Imperial Spirit Formula" is divided into three parts in total, namely Imperial Spirit, Transformation and Soul Building.

To achieve the spirit of the spirit, the premise is to recognize the spirit, and to be able to establish communication with it, everything in this world also has the existence of the spirit, but there are strong and weak, each has a trade-off.

Transforming into a spirit is a method of incarnating thousands of people, which can transform itself into any object that exists between heaven and earth, and without the slightest disobedience; As described in the notes, when cultivating to the spirit building, you can have the ability to create things, and this kind of creation is not the kind of creation that the monk has illusioned, but creation.

After memorizing all the words in the notebook, Fang He came back to his senses from the shock, the content of this notebook was really amazing, it was beyond the scope of his understanding, especially the explanation of the Spirit Building Chapter, which was almost completely beyond the continent and went straight to the origin of the world.

After searching the space again, after making sure that there was nothing missing, Fang He got up and prepared to leave.

But just as he was about to leave, the coffin above his head disappeared, and not only that, but thick chains gradually appeared from all around, forming a cage that trapped Fang He firmly in it; Although these chains were made of iron, no matter what method Fang He used, they could not be destroyed, which made Fang He's joy instantly washed away.

"It's over."

After trying to no avail, Fang He sat on the ground dejectedly, he knew that he would not be so greedy, if he only collected the spirit stones in the coffin, although he would miss this anti-heaven exercise, he would not fall into such a world.

At this point, regret was useless, after sorting out his mood, Fang He had to pick up the notebook again, since he couldn't get out by all the existing means, then the only hope was in this notebook.

However, even though Fang He carefully flipped through the notes several times and was sure that he hadn't missed a word, he still didn't find any clues.

"Do you want me to practice this spirit trick before I can get out?"

With such an idea, Fang He took the notebook and approached the chain; At the moment of approaching, there was a faint fluctuation in the iron chain, although this change was very subtle, but Fang He's divine soul still caught it, thus confirming Fang He's conjecture.

This is a test, for the monks who come here, as long as they pick up the "Imperial Spirit Formula", they can only leave this cage if they cultivate it, otherwise they can only sit here, even if there are more spirit stones, they can't go out, and they are just foreign objects.

Thinking of this, Fang He no longer hesitated, and began to cultivate according to the records on the "Imperial Spirit Formula", but the difficulty of his cultivation was also extremely terrifying, Fang He practiced for three months before he could barely touch the skin of the first chapter of the "Imperial Spirit Formula" - the Imperial Spirit Chapter.
