Duan Heng's judgment is quite correct.

Three directions, three array eyes, one is not bad, I have to say that the person who designed this sword array is really a genius-like character, normal sword formation, whether it is permanent or semi-permanent, can be discovered in advance in some way, in fact, the nature of the sword formation determines that this thing is a dignified weapon, and it is not suitable for sneak attacks and ambushes.

However, the original sword array designers adopted this method, that is, to design a half-cut sword formation first, which was usually in an unfinished state.

And since it is unfinished, it is naturally not a sword formation, and naturally it will not be discovered.

And once necessary, you can immediately activate the mobile array eye, instantly form a sword formation, and kill people invisibly.

It is estimated that this is also the reason why no one has discovered this sword formation for millions of years, or someone has found it, but they all died.

This idea is good, of course, the difficulty is also high, how to perfectly connect the mobile array eye with the previous fixed array eye in an instant, this is definitely a difficult technical job.

Duan Heng didn't plan to explore, his level was not enough.

What he was going to study now was what was hidden beneath this desolate valley?

There is nothing unusual about the three array eyes taken out alone, they are all hidden in the most ordinary mountain cliffs, and the volume is not large, just three palm-sized purple stones, a bit like purple electric stone, but not like it, and the surface of this stone is carved with a circle of extremely profound and strange runes.

Just after looking at it for the first time, Duan Heng knew that this rune was exactly the same as the green dragon rune he had obtained in the three thousand small worlds, although the specific details were different, but it was definitely the same level, or rather, it had the same origin. It's from the same person.

The green dragon rune is very powerful, and I don't know what the origin of this nameless rune is?

After taking a closer look, Duan Heng put the three stones that served as the eyes of the array into the Qiankun bag, and then began to dig and search in the vicinity of the eyes of the array, and he was now at least eighty percent sure that this was a relic of the sword cultivation of ancient humans back then. Maybe it's still complete.

As for whether this is immoral or anything, Duan Heng doesn't care.

The search and excavation was laborious, because the pile of rubble was almost a large area, and there were stones all over the top, bottom, left and right. I can't tell where the ruins are.

But Duan Heng was not discouraged, and in the end, it took a whole day to dig a large stone pit more than ten zhang deep in the same place, and the gravel pushed out around it was piled up into two hills.

And it was only at this time that a cyan texture finally appeared underneath. Extremely smooth and flat large bluestone.

It is a very precious thing, the status and value of the big bluestone in the immortal cultivation world is equal to the mutton fat jade on the earth.

It is the most important and the only designated building material used for the construction of buildings, palaces, altars, and squares.

The reason is not only that this large azure stone is beautiful, but also because it is amazing. There are few production areas, and they are usually only produced in the belly of the mountain. The texture is very warm, and it contains the spirituality of mountains, rivers and lakes, which is not the spirit of the fairy spirit, but the spirit of nature.

If the ground in a person's home is paved with this big bluestone, first of all, it is warm in winter and cool in summer. There are no mosquitoes, poisonous snakes are far away, and the evil spirit is self-leaving, even if it is knocked through a few small pits, cracks or something. As long as the whole thing doesn't shatter, it will be repaired automatically.

Secondly, blessings are self-generated, sleep peacefully at night, calm the heart, and prolong life.

Finally, sitting on this big bluestone, you can vaguely hear the murmur of birds, the murmur of flowing water, the caress of the breeze, the fragrance of flowers and plants, the freshness of distant mountains, and the fragrance of earth.

This is not an illusion, but the natural spirituality of the mountains, rivers and lakes absorbed by the big bluestone in the formation process, which has endured for a long time, and is the first material for decoration and building that is sought after by countless people.

Even in the thirty-six states of Daqian, the big bluestone has become a forbidden, only the five great emperors can use it on a large scale, and even the nine high gates can only use the big bluestone to build some small rooms, as for the use of squares, gardens, hum, it is absolutely sky-high.

On the market, the price of a one-foot square high-grade bluestone is 100,000 immortal stones.

So at this moment, Duan Heng was also stunned for a long time, 30 million years have passed, this big bluestone still maintains its original beauty, gently brushing away the dust on it, he can actually smell the fragrance of flowers and hear the breeze.

It's really good!

Next, Duan Heng was immediately full of energy, not to mention what was down here, even for these high-grade bluestones, he was also developed, who would refuse a rich net worth?

And with the continuous excavation of Duan Heng, more and more large bluestones below this are exposed, and it can be seen that this seems to be a very spacious place, which was buried because of the war.

After fighting for three days and three nights, the relics of this sword cultivation era appeared intact in front of Duan Heng, who would have thought that countless adventurers were heading for the three famous cities, but they didn't know that there was such a treasure hidden under the entrance of the most conspicuous, simplest, and easiest Tianya Ancient Road.

It is an altar, intact and not very large, that is, the size of a three-story villa. There are no tricks in the modeling, it is very simple and simple, but all of them are built of large bluestones, and so many large bluestones, if you take them back and sell them, they are worth hundreds of millions.

However, Duan Heng was not in a hurry to make a move, but carefully observed the inside and outside of this altar, on the outside, he didn't find any traps, thinking about it, this kind of altar was regarded as a very important place at that time, who would be brainless enough to set traps here?

Therefore, after Duan Heng hesitated for a moment, he stepped into it, and there were no prohibitions inside, let alone magnificent decorations, and it could even be said to be very simple.

The only thing that exists in this is the spiritual position.

It's not a person's spiritual position, nor is it the spiritual position of the sword soul, but the spiritual position set up for the sword weapon, in other words, the sword mound!

With a gasp, Duan Heng couldn't help but take a step back, and he was even more fortunate in his heart that he hadn't recklessly demolished this altar.

There are indeed no traps in this place, but there are swords here, and they are primeval swords.

He finally knew how that terrifying primeval sword was formed.

At the beginning, those sword cultivators were really geniuses, and they found such methods, no wonder they could be invincible in the world.

"Forget it, a gentleman loves money and takes it in a good way. Duan Heng said very solemnly, but the hairs on the back of his neck kept standing up, this place is too dangerous, it's better to leave.

It's just that he just thought about it, and before he could escape from this altar, he suddenly felt that the earth sank, and the entire altar actually sank into the ground quickly, and the gravel mountain that he had originally excavated before also shook violently, directly leveling this big pit.

Where else has changed?

It's just that Duan Heng didn't know that in the distance, an almost transparent sword soul was smiling gloomily, and not far away, a mechanical jade talisman shattered into several sections. (To be continued.) )
