After Han Li took a brief observation, he put away the three immortal artifacts, namely the black bone knife, the long square inkstone, and the paperweight, and then stretched out his hand.

On the ground, an eight-treasure heavy letter with a square foot was slowly levitated and landed in front of him.

Each of the four sides of the letter is closed with a lock, and a silver talisman is pasted on it.

After Han Li looked at them for a moment, he found that these four talismans were the "Green Dragon Trapped Wood Talisman", "White Tiger Shimmering Golden Talisman", "Zhu Ming Raising Fire Talisman", and "True Martial Water Repellent Talisman", all of them were the best of the forbidden talismans, both in terms of grade and appearance.

"Actually using the Four Elephant Rune Array to seal this letter, what is hidden in it? What makes the old zombie of Feng Tiandu cherish it so much?" Han Li muttered to himself with doubts in his heart.

As he spoke, he pinched the magic trick, and the golden light around him burst out, and he began to crack the four-elephant rune array.

The reason why the Four Elephant Rune Array is difficult to crack is that the power of the four elephants complements each other and is the backbone of each other, so it cannot be cracked one after another, but must be unraveled at the same time, otherwise it is very likely to lead to the direct collapse of the things in the letter.

Therefore, the best way to crack it is to have four people with similar cultivation work at the same time to crack it together.

Han Li didn't do that, his approach was even more simple and rude, he actually directly summoned the Truth Wheel to envelop it, and without waiting for the four talismans to produce a chain reaction, he dissolved them one by one in an instant.

After successfully removing the four talismans, the trap buckle of the Eight Treasures Heavy Letter Quartet Lock snapped open.

Han Li grabbed the lid of the heavy box with both hands, lifted it, and took it off.

As the lid of the box opened, there was no aura burst or a treasure in the heavy letter, and there was not even a single fluctuation of spiritual power coming out at all.

He leaned over and found that inside the heavy letter, there was a waxy ancient book, a black jade plate the size of a palm, and black nails neatly stacked around it.

He took out the sallow ancient book first, and under the touch of his palm, he only felt a little slippery, as if it was made of some kind of beast skin, and there was still a little residual temperature on it.

On the cover of the ancient book, there are four big characters written "Phantom Treasure Book".

Seeing this name, Han Li couldn't help but raise his eyebrows, feeling a little familiar.

After thinking about it for a while, it dawned on him.

Back then, when he was looking for the time exercise through the Impermanence Alliance, he had heard people say that there was an exercise in the Fuling Sect that could cultivate the law of time, but it was this scripture.

Regarding the time exercises, the only thing Han Li had been exposed to was the Truth Wheel Sutra, so there was no way to deepen his understanding of the law of time by corroborating and comparing it with other exercises.

The appearance of this "Phantom Treasure Book" gave him the opportunity to do this.

Han Li's eyes flashed with a strange color, and he suddenly remembered something, and hurriedly pinched his hands quickly, summoning the Truth Treasure Wheel.

But seeing the huge eyeball on the treasure wheel, a golden light shot out of it and hit the sallow ancient books.

The golden light on the surface of the ancient book flickered slightly, and then it disappeared, and there was no more movement.

Seeing this, a look of disappointment flashed across Han Li's face, so he put away the magic trick and took the Truth Treasure Wheel back into his body, muttering to himself:

"It seems that this thing is different from the stone tablet in the Candle Dragon Road, although it is also a thing that records the time exercise, but it does not have the power of the time law......"

With his divine sense, he was powerful, but after a meal, this "Phantom Treasure Book" was read by him.

As a result, Han Li was pleasantly surprised to find that although this exercise was also about the power of the law of time and the way of enlightenment, both the method of cultivation and the description of the exercise were very different from the "Truth Wheel Sutra", especially the mention of the "Phantom Sand Realm", which seemed to affect the power of time in a certain area after cultivation.

However, at the moment, whether it is Feng Tiandu or Qi Yunxiao, it seems that their cultivation of this exercise is very limited, at least when they are fighting against others, they cannot use it against the enemy.

Although Han Li couldn't wait to plunge headlong into this exercise at this moment and ponder it carefully, in this way, it would be hundreds or thousands of years of retreat, which was naturally undesirable in the current situation.

He forcibly pressed the thoughts in his heart, put away the "Phantom Treasure Book", and later had time to explore it again.

After taking a deep breath, Han Li picked up the black token again and looked at it.

I saw that the top of the token was extremely smooth, the outer layer was shining with a transparent luster, but the inside was as black as ink, and it looked like a ball of ink was frozen in ice crystals.

The surface of the token is slightly convex and engraved with the words "Dry Heaven Fuling", I don't know if it has another meaning, or represents the identity of the Great Elder of Fengtiandu.

Having learned from the previous experience of the Gong Jiu Token, Han Li had laid out a layer of magic circles around him before he crossed the immortal spirit power into this order to try to see if he could drive this thing.

As a result, no matter how much he tried, the black token remained unmoved, as if it were a dead thing.

After several experiments, he couldn't come up with a result, so Han Li had no choice but to give up.

In the Eight Treasures Heavy Letter, in addition to these two things, there are only some black iron nails left, and there are quite a few of them, and after a careful count, there are a full eighty-one.

Han Li casually took one out of his hand, put it in front of his eyes and carefully observed it for a while, and found that the iron nail, which was only a finger long, was actually densely engraved with various patterns, and there were some kind of strange beasts and many strange runes on it, and he knew at a glance that it was not a mundane thing.

And around the iron nail, there seemed to be wisps of ink-like black mist, which was very secretive.

After Han Li took out all the iron nails, he suddenly found that at the bottom of the Eight Treasure Heavy Letters, there seemed to be a black iron plate embedded in it, and there were deep and shallow ravines crisscrossing it.

After he took out the iron plate, he found that it was covered with spiritual patterns, and it was actually a well-grade array plate, and in the lower left corner, there was also a string of protruding words, which read: Dry Heaven Fu Ling, Array Guarding All Directions.

"This ...... Could it be a mountain guarding array?" Han Li muttered as he held the array plate in one hand and the token in the other, glancing at the eighty-one black iron nails on the ground.

With this in mind, he flipped the array over and found that there was a sunken groove on its back, the outline of which was exactly the same size as the black token in his hand.

His heart moved, and he lowered the token towards the groove.

There was a soft "click".

The token was embedded impartially, and the black ink inside suddenly overflowed, and the black ink inside flew out like a swimming dragon, cruising on the surface of the array.

But seeing that where the ink dragon passed on the array plate, where the vertical and horizontal lines intersected, there was a dark golden light lit up.

Seeing this, a hint of joy flashed in Han Li's eyes, and he hurriedly refined the array disk and token together.

Then he placed it on the earth, so that it was connected to the entire island, and then he twisted a black iron nail and released it towards a dark golden point of light on the array.

As soon as he saw that as soon as the iron nail Fang touched the range of the array disk, he was immediately hit by a powerful attraction, and suddenly broke free from Han Li's hand, and with a "Zheng" sound, it was nailed into the dark golden light point.

Almost at the same time, a loud bang was heard in the dense forest not far east of the island.

When Han Li raised his head to look over, he saw a pillar of jet-black light more than hundreds of feet tall rising from the ground, pointing straight into the sky.

There seemed to be a strange beast entrenched on it, and a faint black air was constantly flowing out on the surface.

"That's really the case......" Han Li was overjoyed in his heart, and continued to twist the iron nail and place it towards the array plate.

As the sound of "Zheng" continued to sound, black iron nails fell into the array one after another, and there were constantly black pillars of light rising out of thin air on the island.

After the last pillar of jet-black light also rose into the sky, the black mist surrounding the pillar of light suddenly dispersed, merging with each other, and soon turned into a layer of pale black light curtain, enveloping the entire island.

Immediately after, those jet-black pillars of light that appeared all over the island began to fade, and they actually became transparent little by little, until they disappeared into the void.

After a while, the curtain of light that enveloped the island disappeared, and it looked as if nothing had happened.

However, on the array in front of Han Li, a small island that was shrouded and sheltered by the formation had already appeared.

After looking at it for a moment, he stood up, and with a flash of his figure, he flew out of the island.

When he passed through that layer of light curtain, Han Li could clearly feel a feeling of being swept by spiritual power fluctuations, but since he had already refined the magic circle, he would naturally not be affected in any way.

Looking from outside the island, the entire island did not change in the slightest, and there was no formation coverage at all, nor could he feel any spiritual power fluctuations, but when Han Li probed with the Ming and Qing Spiritual Eyes, that layer of island protection array was undoubtedly revealed.

He flew out of Kojima in one breath, raised one hand to grasp the fist, mobilized the immortal spirit power in his body, and bombarded Kojima with a punch.

Just listen to the loud "boom"!

The entire void was stirred, and a huge fist shadow the size of a hundred zhang was born out of thin air, squeezing the vitality of heaven and earth, layer upon layer like ocean waves, and rolling towards the three-color island.

As soon as the two came into contact, the magic circle barrier, which was originally invisible to the naked eye, suddenly emerged.

The black light on it was magnificent, and one after another ink-colored swimming dragons continued to rise out from the eighty-one black pillars of light, gathering towards the place where the fist shadow was falling, operating the power of the formation, and resisting it.

Above the island, there was a sudden roar, and a depression dozens of feet deep was pressed out on the black light curtain, which seemed to be precarious, but there was no sign of collapse.

Seeing this, Han Li couldn't help but nod secretly.

Although he didn't exert all his strength in this punch, it was inspired by the real mid-stage cultivation of the Golden Immortal, and the power was really not small, if it was an ordinary True Immortal level sect's mountain protection array, I was afraid that it would have already collapsed.

According to Han Li's estimation, the defensive limit of this "Dry Heaven Fuling" formation should be slightly inferior to the layer of formation that the Northern Han Immortal Palace had laid out in the Candle Dragon Dao when it was dealing with Baili Yan.

However, Rao is so, and this treasure is enough to be impressive.

You must know that the general sect protection array needs to select the mountain roots with abundant spiritual energy as the foundation of the formation in various parts of the sect, and arrange specially refined array flags and pillars to suppress the formation, so as to ensure the power of the established formation.

It's just that although this kind of formation is powerful, it belongs to the dead formation, which cannot be moved and changed, and it is not easy to be broken by people from the outside world, but it is easy to be manipulated from the inside to destroy the formation and the formation pivot.

This Dry Heaven Fuling Array, which is only launched with an array disk, is a living array, which can be put away at any time, which is not only very convenient, but also not easy to be damaged.

After some temptation, Han Li even faintly felt that this thing should be a shortened version of the Fuling Sect's true mountain protection array, and he was naturally quite happy in his heart.

In the future, if you open a cave elsewhere, you can naturally save a lot of trouble with this treasure in hand.
