My talisman pen is omnipotent. How should you deal with it?

The tunnel is narrow and winding, like an endless maze, giving people a deep sense of depression and mystery.

Chu Ci walked carefully, not knowing whether there would be any danger ahead, so he remained highly alert.

After walking for about half an hour, an open space about an acre in size suddenly appeared in front of them, which made Chu Ci, who had been in a nervous state, breathe a sigh of relief.

He looked around and found several abandoned weapons scattered in the corner, among which a fiery red fan was particularly eye-catching.

Chu Ci took a closer look and immediately recognized that this fan was the magic weapon used by Han Feiyu during his Qi Refining Stage.

He couldn't help but think of the past with Han Feiyu, and a complex emotion surged in his heart.

Chu Ci also noticed some traces of spiritual power remaining on the wall.

He deduced that there had been a formation here, but it had been destroyed. There was no doubt that the person who broke the formation must be Han Feiyu, and the spell book in his hand was most likely obtained here.

Chu Ci observed carefully, not missing any details, and only continued to move forward along the tunnel after he was sure that there were no useful clues here.

After walking for about another half an hour, the road ahead suddenly opened up. The originally narrow and dark passage turned into a wide and bright space in an instant.

A mysterious formation emitting a faint blue light came into view.

The space occupied by this formation is exactly the same as the one that Han Feiyu had cracked before. The only difference is that it is slightly larger.

Chu Ci's heart was shocked, and he couldn't help but develop a strong interest in this mysterious formation.

In front of the formation, all kinds of sundries were placed in a disorderly manner, including broken magic weapons, empty spirit stone ashes, incomplete candles and broken medicine bottles. It looked very chaotic.

Chu Ci approached the formation cautiously and looked at the scattered items.

It seems that these traces were left by Han Feiyu. It can be imagined that he must have spent a lot of effort on this formation, but he failed to crack it after all.

Perhaps the "Secret Book of Talisman Array" mentioned in the previous book is in this mysterious array. Thinking of this, Chu Ci made up his mind to give it a try.

The reason why he was so confident was that he had the powerful formation called the Boundless Formation in his hands. Coupled with the mid-grade spirit stones given by Song Henian, it should not be difficult to break the formation in front of him.

Chu Ci did what he said, and quickly placed the 24 flags of the Boundless Array one by one. Then, he placed the middle-grade spirit stone in it, and the Boundless Array instantly burst into a dazzling light.

If there is no external intervention and assistance, it will probably take a long time to break through the Unbounded Array. And it is also unknown whether the number of medium-grade spirit stones in Chu Ci's hand is enough to support it to the end.

So Chu Ci used the Golden Eye Technique to find the flaws in the formation.

Time passed by minute by minute, until after adding more than 2,000 medium-grade spirit stones, he finally noticed a subtle change in the vibration position of the formation. The formation structure, which was originally as solid as a rock, now showed a slight sign of loosening that was barely noticeable.

Although this slight loosening was fleeting, it did not escape Chu Ci's eyes. He immediately realized that this was the key to breaking the formation.

Now that we have found the center of the formation, we should attack immediately.

In fact, Chu Ci has a secret weapon for breaking the formation, that is the golden pen. Its power is enormous, far exceeding that of magic weapons. It should not be difficult to destroy the formation.

Chu Ci used his spiritual power to activate the golden pen on his chest. In an instant, the golden pen burst into light and turned into a golden stream of light that rushed straight towards the shock position. There was a loud "boom" sound, deafening, and the entire formation trembled slightly.

Chu Ci struck while the iron was hot and continued to bombard the Zhen position with his golden pen.

Every time the pen tip touches the formation, it will cause an earth-shaking roar, accompanied by strong energy waves sweeping around.

Under the continuous powerful force of the Boundless Formation and the fierce attack of the golden pen, the originally indestructible formation gradually became shaky and vulnerable.

Three hours later, there was a sudden crisp and pleasant sound, like the sound of crystal breaking. Then, the entire formation seemed to be violently hit by an invisible force and collapsed in an instant.

As the formation was destroyed, the mysterious power that had originally enveloped this place also dissipated without a trace, and it became an ordinary space that was no different from before.

Chu Ci stepped in and quickly glanced around, his eyes stopping on a yellow package placed in the corner of the room.

He untied the rope wrapped around the outside, and an old book appeared before his eyes. It was the "Secret Book of Talisman Array" mentioned before.

The signature on the cover also reads "Written by Master Jinfu" in tiny calligraphy.

Chu Ci casually flipped through a few pages first, and a feeling of surprise surged in his heart.

What is recorded in the book are some unique secret techniques that skillfully combine talismans and formations, and Master Jin Fu collectively calls these unique skills "talisman formations."

Chu Ci was quite interested in the first talisman array in the book. This talisman array was related to the teleportation array.

Chu Ci sat on the ground and studied it in depth for most of the day, and only then did he have a slight understanding of this talisman formation.

Simply put, after this kind of talisman array is successfully refined, you can carry the teleportation array with you at any time.

For example, first build a teleportation array in a certain place, and then refine a talisman array that matches it. Then when this talisman array is activated, the user can travel through space and reach the location of the teleportation array in the blink of an eye.

But in actual application, it also has many limitations.

The first and foremost issue is the distance problem: as the usage distance increases, the difficulty of refining the talisman array increases exponentially.

According to the records in Master Jin Fu's book, he could only refine a short-range talisman array. Once it exceeded 10 million, even a peerless master like Master Jin Fu would not be able to refine it successfully.

Another aspect is spirit stones. Just like using traditional teleportation arrays, each time this array is activated, a huge number of spirit stones are needed as energy support.

Short-distance transmission requires about ten thousand spirit stones, medium-distance transmission requires medium-quality spirit stones, and long-distance transmission requires high-quality spirit stones. In short, the longer the distance, the higher the quality of the spirit stones required, and the amount consumed is the same.

Even so, the practicality of this talisman array is still beyond doubt. If such a teleportation array can be set up in the mysterious cave, wouldn't it mean that one can freely travel back and forth between the spiritual medicine garden as he pleases, which will undoubtedly bring great convenience.
