After a brief observation, Han Li put away the three fairy weapons, the black bone knife, the long inkstone, and the paperweight, and then waved his hand.
Above the ground, a square Eight Treasure Heavy Letter slowly floated up and fell in front of him.
The heavy letter was sealed with a mechanism lock on each side, and there was a silver talisman on each side.
After Han Li looked at it for a moment, he found that the four talismans were "Green Dragon Wood Trap Talisman", "White Tiger Gold Talisman", "Zhu Ming Fire Talisman", and "Zhen Wu Water Repelling Talisman". Whether it was the grade or the quality, they were all the best among the talismans.
"He actually used the Four Symbol Talisman Formation to seal this letter. What is hidden in it?
Why does Feng Tiandu, the old zombie, treasure it so much? "Han Li was puzzled and murmured to himself.
As he spoke, he made a gesture, and the golden light around him shone brightly. He began to break the Four Symbol Talisman Formation.
The reason why the Four Symbol Talisman Formation was difficult to break was that the power of the four symbols complemented each other. Therefore, it could not be broken one by one, but must be broken at the same time. Otherwise, it was very likely that the item in the letter would be destroyed.
Therefore, the best way to break it was to have four people with similar cultivation to break it at the same time.
But Han Li did not do so. His method was even more simple and crude. He directly called out the Wheel of Truth and shrouded it. Before the four talismans could cause a chain reaction, he removed them one by one in an instant.
After successfully removing the four talismans, the mechanism of the Eight Treasures Heavy Envelope's lock popped open with a "click".
Han Li grabbed the cover of the heavy letter with both hands, lifted it up, and took it down.
As the cover of the box was opened, there was no burst of spiritual light or strange phenomenon of treasures in the heavy letter. There was not even the slightest fluctuation of spiritual power.
He leaned over to take a look and found that inside the heavy letter, there was a waxy yellow ancient book and a black jade the size of a palm. There were also black nails neatly arranged around it.
He first took out the waxy yellow ancient book. When he touched it with his palm, he only felt that it was a little slippery. It seemed to be made of the skin of some kind of beast, and there was still some residual heat on it.
On the cover of the ancient book, four large words were shockingly written: Fantasy Star Treasure Codex.
Han Li couldn't help but raise his brows when he saw this name. He felt that it was somewhat familiar.
After thinking about it, he came to a sudden realization.
Back then, when he was searching for a time cultivation method through the Anicca Alliance, he had heard someone mention that there was a cultivation method in the Fu Ling Sect that could cultivate the Law of Time, and it was this scripture.
Regarding time cultivation techniques, the only one that Han Li had come into contact with was the True Word Transmutation Scripture, so he had no way to compare it with other cultivation techniques to deepen his understanding of the laws of time.
The appearance of the Illusionary Star Codex gave him the opportunity to do this.
A strange light flashed in Han Li's eyes, and he suddenly thought of something. He hurriedly formed a seal with his hands to summon the Wheel of Truth.
The huge eyeball on the treasure wheel slowly turned, and a golden ray of light shot out from it, hitting the yellow ancient book.
The golden light on the surface of the ancient book flickered for a moment before disappearing completely.
Seeing this, a trace of disappointment flashed across Han Li's face. He then put away the technique and kept the Wheel of Truth back into his body. He muttered to himself,
"It seems that this thing is different from the stone tablet in the Torch Dragon Path. Although it also records the time cultivation technique, there is no power of the law of time on it …"
With the strength of his Divine Sense, in the time it took to eat a meal, this 《Illusionary Star Treasure Tome》 was flipped through once by him.
As a result, Han Li was pleasantly surprised to find that although this cultivation technique was also about the power of the law of time and the way to comprehend it, whether it was the cultivation method or the description of the cultivation technique, it was completely different from the True Word Transmutation Scripture. Especially the "Illusionary Star Sand Realm" mentioned, it seemed that after cultivating it, it could affect the power of time in a certain area.
But now it seemed that whether it was Feng Tiandu or Qi Yunxiao, it seemed that their cultivation of this cultivation technique was very limited. At least, they couldn't use it against the enemy when fighting with others.
Han Li wanted nothing more than to immerse himself in this cultivation art and carefully study it, but if he did that, he would have to go into seclusion for hundreds or even thousands of years, and that was definitely not an option under the current circumstances.
He forcefully suppressed the thoughts in his heart and kept the Illusionary Star Treasure Codex. When he had time in the future, he would have to explore it.
After taking a deep breath, Han Li picked up the black token and checked it again.
He saw that the surface of the token was extremely smooth. The outer layer was shining with a transparent glow, but the inside was as black as ink. It looked like a ball of ink was frozen in ice crystals, about to condense, but one could still see the ink flowing.
The surface of the token was engraved with the words "Fu Ling of Gantian". Who knows if it had another meaning or if it represented Feng Tiandu's identity as the Grand Elder.
With the previous example of Gong Shujiu's token, Han Li placed a layer of formation around it before injecting celestial spiritual power into the token to try to see if he could activate it.
In the end, no matter how he tried, the black token didn't move at all, like it was a dead object.
After a few tests, he wasn't able to get any results. As such, Han Li could only give up.
Within the Eight Treasure Heavy Letter, apart from these two items, there were only some black iron nails left. There were many of them, counting them, there were a total of 81 of them.
Han Li casually took one out, placing it in front of his eyes to observe it. He noticed that the iron nail, which was just a finger long, was actually covered in all sorts of patterns. On it were some weird beasts and also many weird runes. One look and one knew that it wasn't an ordinary item.
Moreover, around the iron nail, there seemed to be ink-like black mist wrapped around it. It was really secretive.
After Han Li took out all of the iron nails, he suddenly discovered that there seemed to be a black iron plate embedded in the bottom of the Eight Treasure Heavy Envelope. There were deep and shallow grooves crisscrossing the surface of the black plate.
After he took out the iron plate, he noticed that it was covered in spiritual patterns. It was actually a high grade formation plate. At the bottom left corner, there was a string of words protruding out. On it was written: Gantian Mountain Guards, Formation Guards 8 Directions.
"This … Is this a mountain guarding formation?"
Han Li held the formation plate in one hand and the token in the other. Looking at the 81 black iron nails on the ground, he muttered to himself.
Thinking about that, he flipped the formation plate over. In the end, he noticed that there was a dent on the back. The size of the dent was the same as the black token in his hand.
With a thought, he placed the token into the dent.
"Ka", there was a light sound.
The token was perfectly embedded in. Instantly, a dark light flowed on it. The black ink inside flew out like a dragon and started to swim around the surface of the formation plate.
Wherever the black dragon passed, the crisscrossing lines on the formation plate would light up with a dark golden light.
When Han Li saw that, a look of joy flashed in his eyes. He hurriedly refined the formation plate and the token together.
Then, he placed it on the ground, connecting it to the entire island. He then picked up a black iron nail and placed it towards a dark golden light spot on the formation plate.
The moment the iron nail came into contact with the formation plate, it was immediately attracted by a strong suction force. It suddenly broke free from Han Li's hand. With a "Zheng" sound, it nailed into the dark golden light spot.
Almost at the same time, in the dense forest not far from the east of the island, there was a loud rumbling sound.
When Han Li looked up, he saw that there was a black light pillar thousands of feet tall rising from the ground, pointing straight into the sky.
There seemed to be a strange beast entrenched on it. On the surface, there was a faint black energy flowing out.
"As expected …" Han Li was delighted. He continued to pick up the iron nail and place it on the formation plate.
With the continuous "Zheng" sound, black iron nails fell into the formation plate one after another. There were also black light pillars rising from the island.
When the last pillar of black light rose into the sky, the black mist surrounding the pillar of light immediately dispersed and fused with each other. Very quickly, it turned into a layer of faint black light that enveloped the entire island.
Immediately afterward, the black light pillars that appeared everywhere on the island began to fade. They became transparent little by little until they disappeared into the void.
Not long after, the light barrier that enveloped the small island also disappeared, as if nothing had happened at all.
However, on the formation plate in front of Han Li, there was already a small island that was covered and protected by the formation.
After looking at it for a moment, he stood up and flew out of the island in a flash.
When passing through the layer of light curtain, Han Li could clearly feel a feeling of being swept by spiritual power. However, because he had already refined the formation, he naturally would not be affected.
From the outside, the entire island hadn't changed in the slightest. There were no formations enshrouding the island, nor were there any spiritual power fluctuations emanating from the island. However, when Han Li used his Brightsight Spirit Eyes to inspect the island, he was immediately able to identify the protective formation.
He flew thousands of feet away from the island in one breath. He raised one hand into a fist, mobilized the Celestial Spiritual Power in his body, and blasted a punch toward the island.
"Boom!" A loud sound was heard!
The entire void surged, and a huge fist shadow of a hundred feet in size appeared out of thin air. It squeezed the Heaven and Earth Yuan Qi, layer upon layer like waves, and rolled toward the tricolor island.
As soon as the two sides came into contact, the formation barrier that was originally invisible to the naked eye suddenly emerged.
The black light on it was dazzling. Black dragons constantly rose from the 81 black light pillars and gathered toward the place where the fist shadow was rolling. The power of the formation was used to resist.
Above the island, there was a constant roar. The black light curtain was pressed into a depression of dozens of feet deep. It seemed to be in danger, but there was no sign of collapse.
Seeing this, Han Li couldn't help but nod secretly.
Although he did not use his full strength in this punch, it was unleashed with the cultivation of a Middle-stage Golden Immortal, so its power was not small. If it was the Mountain Guarding Formation of an ordinary True Immortal Sect, even the foundation of the formation plate would have collapsed.
According to Han Li's estimation, the defense limit of this "Heaven and Earth Ambush" formation should be slightly inferior to the layer of formation that the Northern Frost Immortal Palace set in the Candle Dragon Path when they dealt with Bai Liyan.
However, even so, this treasure was enough to make people look at it in a different light.
One had to know that a normal Sect Protecting Array required the selection of mountain roots with abundant Spirit Qi throughout the sect as the foundation of the Array Formation. Then, specially refined Array Flags and Array Pillars would be set up to support the Array, thus ensuring the power of the established Array Formation.
It was just that although the power of this formation was great, it was a dead formation. It couldn't be moved or changed, and it was not easy to be broken from the outside. However, it was easy to be tampered with from the inside, destroying the formation's foundation and the formation pivot.
This Heaven and Earth Ambush Formation could only be activated by the formation plate, but it was a live formation that could be taken away at any time. Not only was it very convenient, but it was also not easy to be destroyed.
After some testing, Han Li even faintly felt that this thing should be the simplified version of the real mountain protection formation of the Fu Ling Sect, and he was naturally quite happy in his heart.
