The place where the Grandmaster-level formation becomes a Grandmaster-level formation, firstly, it can form its own space, and secondly, it can be trapped even by a Divine Sea Realm Grandmaster-level powerhouse.

As he continued to go deeper, Ding Yan gradually discovered that the runes in this spatial formation were indeed composed of many levels of runes.

Like the runes on the square table before, it is the simplest one, it is a first-level rune, followed by the gray-brown wall around it, the runes on the wall are more difficult than the runes on the square table, but compared to the runes on the square table, it is much simpler, composed of second-level and third-level runes, and the runes contained in the space are the foundation of this formation, and it is also the most complex one, which is composed of fourth-level and fifth-level runes.

Now Ding Yan has unlocked the first-level runes, as for the second-level and third-level runes, it shouldn't take much effort, but the fourth-level runes, so far, he has not been able to take out one.

Moreover, extraction is extraction, Ding Yan has also carved similar runes, but they have all failed, it is obvious that cracking and portraying are two different things, compared to carving, cracking is obviously much easier, just like creating and destroying, the latter is definitely much easier.

Half a month later.

Ding Yan, who had been sitting cross-legged, suddenly got up and walked to the broken square table.

The moment he stepped into the void where the square table was located, a terrifying rebound force pressed down on Ding Yan, like the palm of a giant's hand, wanting to suppress Ding Yan directly.

Ding Yan looked calm, did not retreat, but advanced, and took another step forward.

In his eyes, a cloud of yin and yang qi rotated slowly, at this time, in his eyes, the suppressed power was not this space, but a piece of runes connected together, these runes were arranged in an orderly manner, criss-crossed, and after being connected together, a terrifying force was formed, wanting to press Ding Yan back to the ground.

Seeing the situation, Ding Yan shook his right hand casually, and made a few seals, which seemed to move slowly, but in fact it was only an instant.

After the seal flew out, it slammed into the runes.

After the space formed by the runes was hit by the seal, it was like being hit by a boulder on the cloth, and it was frantically compressed backwards, but this situation did not last long, a more terrifying huge force was generated, and Ding Yan's eyes clearly saw several runes flashing with purple light.

"Sixth-level runes!"

Ding Yan's eyes flashed, and after remembering the location of those runes, he flashed back to the ground.

Rumble!

The huge rebound force directly shattered several seals sent out by Ding Yan, and the terrifying power echoed in the space.

Two days ago, Ding Yan had already found a way to extract fourth-level runes, but as his understanding deepened, he soon discovered that there should be more esoteric runes hidden in the depths of space.

On the ground, Ding Yan sat down cross-legged again.

I don't know how long it took, Ding Yan stood up suddenly, and the essence flashed in his eyes.

"Close!"

The power of the Yuan Shen was displayed, Ding Yan grabbed it, and his right hand directly sank into the gray-brown wall, as if deep into the water, and the wall rippled, and immediately, Ding Yan's right hand was closed, and a dark blue rune beat wildly.

"Level 5 Rune!"

Ding Yan's eyes flickered, and he breathed a sigh of relief in his heart.

A level 5 rune is not enough to destroy the walls of this house. Later, there are many more.

Sitting on the ground again, in front of him, the runes from level one to level five were lined up one by one, and began to be arranged in the order of memory.

With the deepening of the understanding of the formation, Ding Yan can already use these existing runes to arrange several simple formations, but unfortunately, so far, Ding Yan has not succeeded in carving a single rune.

The way of the formation, every refinement is extremely difficult, if you want to reach the realm of the grandmaster, in addition to the accumulation of time, the more important thing is the understanding, the understanding is insufficient, even if you have been enlightened for ten thousand years, it is in vain.

Although Ding Yan's comprehension is not superb, it is not bad, not to mention that there is a complete grandmaster-level rune array in front of him for him to comprehend, so during this period of time, Ding Yan's formation attainments can be said to have improved by leaps and bounds.

The runes are neatly arranged one by one, and if you look at them carefully, you will find that these runes are all three first-level runes surrounded by a second-level rune, and three second-level runes surround a third-level rune, layer by layer, and the most central part is the fifth-level rune that Ding Yan took out.

Ding Yan sat in the center, his eyes flickering yin and yang, and every time his hands shook, a rune would be punched.

After the rune fell, without waiting for it to flicker, the power of the primordial spirit that Ding Yan had played would follow and fix it in that position.

Gradually, the scope of the runes became larger and larger, and on each rune, there was a trace of Ding Yan's Yuan Shen power, and on the fifth-level runes, Ding Yan even extracted the immortal power contained in the Yuan Shen power and sealed it in the runes.

The root of the primordial god is the power of immortality. Every Condensing Truth Realm martial artist has more or less immortal power in the primordial spirit in his body.

The deeper the cultivation, the more refined and powerful the immortal power contained in the primordial god in the body, the grandmaster of the Shenhai realm, the immortal power in the body has formed an immortal sea, the immortal sea inhabits the primordial god, referred to as the divine sea, only by producing the immortal sea, the primordial god can give birth to immortal brilliance.

As time passed, there were more and more runes on the ground, and they became more and more dense, just like the shape of a spider, and the more they reached the edges, the weaker the power of the runes, and the correspondingly, the more and more numerous.

Among them, there was a sixth-level purple rune.

"Gather!"

Suddenly, Ding Yan snorted lightly.

A ray of light spilled out of his hand and landed on the purple rune in the center.

Immediately, a ring of light escaped, and for a while, all the runes lit up, flickered for a while, and then gradually disappeared.

Ding Yan saw the situation and his eyes flashed.

"What about the grandmaster-level formation? Today, I, Ding Yan, will break the formation with the formation and break the talisman with the talisman."

If it was the person who arranged the formation to control the formation personally, Ding Yan would naturally not be able to escape, but the formation in front of him was obviously impossible for someone to control.

During this period of time, while Ding Yan comprehended the formation, he gradually figured out some things, that is, in this Netherworld Dead City, the danger can be roughly divided into two types.

One is the danger of a headless ancient corpse or an iron coffin demon corpse.

This kind of danger belongs to the most direct danger, after encountering it, there is basically no choice but to run away and dodge, of course, there may also be some great powers, which can fight those monsters, but Ding Yan is obviously not among them for the time being.

Another danger is that, like the formation in front of you, it belongs to the prison form.

This kind of danger is mainly trapped people, such as the Void Illusion Divine Technique that Ding Yan encountered before, and the Grandmaster-level formation in front of him all belong to this list. Compared to the first danger, this situation was obviously much safer, and due to the fact that no one was *.longitudinal, whether it was the Void Illusion Divine Technique or the Grandmaster-level Formation, they could not exert all their power, and in this way, there was a glimmer of life for the trapped people.

After the formation was hidden, the ground gradually trembled.

Breaking the formation with the formation is different from breaking the formation with force, the caster not only has the talent of the formation, but also has the corresponding strength, and within the grandmaster-level formation, it is even more so, because the grandmaster-level formation has its own space, and if it is arranged in the formation, it must be supported by strength.

Ding Yan planned to use his own strength to break this grandmaster-level formation that had existed for an unknown amount of time
