"Very good, Lin did what he said. As for what Lin said, it is to plant ghost spirit flowers on you in your current state" Lin Sen smiled weirdly, and with a move in his heart, the soul blood of the demon thief in his body fluctuated violently again, and the demon thief's languishing expression showed a trace of horror, until he lost consciousness and was dying, Lin Sen made a move to seal the soul bell, pinched the trick with both hands, and the soul sealing bell suddenly emitted a crisp sound, and at the same time, sound waves appeared, covering the body of the demon thief.

"Soul Seal!"

Lin Sen snorted lightly, pinched his fingers, and the Soul Sealing Bell turned into an illusory shadow and was instantly enveloped in it. At this time, Lin Sen saw that the soul of the demon thief was completely shrouded in the illusory Soul Sealing Bell, so his soul was naturally protected by the Soul Sealing Bell.

At this moment, Lin Sen's right tiger tooth gently cut a bloody hole in his arm, poking a ghost spirit flower into his flesh.

But after being planted on the body of the Demon Thief, the Ghost Spirit Flower immediately withered quickly at a speed that was visible to the naked eye, and quickly disappeared into the Demon Thief's arm.

Looking at the scene in front of him, Lin Sen was not surprised, but a trace of essence flashed in his eyes, and in his mind, Gu Soul had a description of the phenomenon in front of him, which showed that the body of the demon thief met the requirements of cultivation, and it was a good cultivation body.

Lin Sen planted two ghost spirit flowers in his abdomen and thighs one after another according to the method just now. They also quickly withered and disappeared into the body of the Demon Thief the moment they were planted.

Although the ghost spirit grass withered, in fact, it left seeds in the body of the demon thief, and the flowers turned into skeletons to find the soul of the demon thief, but with the protection of the soul sealing bell, the ghost spirit flower will never be able to find the soul of the demon thief. In this way, the skeleton will return to the seed it left behind, and continue to absorb the Qi of the Demon Thief's Yang Death, and over time it will be able to form the best ghost spirit flower.

The premise is to ensure that the vitality of the demon thief is not extinguished, and at this point, when he found that the three ghost spirit flowers were submerged in his body, he saw that his arms, abdomen, and thighs were atrophied to varying degrees, and the demon thief's dead aura became more and more intense, and Lin Sen's expression instantly became solemn.

He immediately pressed the demon thief's body with one hand, constantly injecting spiritual power into him to keep his vitality alive. But this method was extremely expensive, and in less than a quarter of an hour, Lin Sen felt that his spiritual power was rapidly depleted.

So he immediately took out a medium-grade spirit stone, swallowed it like a whale to absorb the spiritual energy contained in it, and quickly replenished it to maintain the vitality of the demon thief once again.

And so it was a day later.

As Lin Sen continued to transmit spiritual power into the Demon Thief's body, he felt more and more frightened, and he found that the Demon Thief's body was like a bottomless pit, consuming nearly a hundred medium-grade spirit stones in just one day!

You must know that if all of these nearly 100 mid-grade spirit stones were absorbed by Lin Sen, it would almost make his cultivation climb to the peak of the early stage of Ning Yuan!

Nearly 100 medium-grade spirit stones are an extremely huge wealth for the monks in the foundation building period, and even a big faction like Huaguang Sect does not receive as many as 100 medium-grade spirit stones in a year.

Lin Sen felt heartache, and immediately thought of the book "The Way of the Forbidden Formation" that he had purchased in Huaguang Zongfang City, in Feng Chenzi's memory, there was such a formation that could gather the surrounding spiritual energy for his own use, which could greatly reduce the consumption of spirit stones.

Thinking of this, Lin Sen immediately took out the slightly old book and immediately flipped through it.

There are many formations and diagrams recorded in it, which is clear at a glance. Soon, Lin Sen found a page about the formation of gathering aura.

Gathering Array.

The materials required for this array are only spirit stones, the higher the quality of the spirit stones, the stronger the formation, and the more aura gathered, even if there is no place with the slightest spiritual energy, if this array is arranged, it can also greatly weaken the consumption of spirit stones, and almost the vast majority of monks will arrange spirit gathering in their cultivation places to achieve twice the result with half the effort.

Lin Sen was overjoyed in his heart, grabbed a handful of medium-grade spirit stones, and then arranged them around, and he arranged three spirit gathering arrays in one go, and got up around himself and the demon thief. Each formation has more than a dozen medium-grade spirit stones as consumable materials.

When the three formations were completely arranged, a very rich spiritual power emanated from the three formations, and it even caused a trace of extremely weak spiritual energy to condense towards the formation in the place around Lin Sen where there was originally not the slightest fluctuation of spiritual energy.

Since the formation arranged by Lin Sen was made of medium-grade spirit stones, he even extravagantly posed three formations, which were skillfully combined on the basis of the three formations, thus forming a majestic aura vortex, which appeared above Lin Sen.

Due to the appearance of the aura vortex, the faint aura in the range where Lin Sen was located and farther away was also attracted, forming a trickle of aura and flowing into the formation.

Lin Sen instantly felt that he had an endless supply of spiritual energy at this moment, and in addition to being excited, he immediately sent spiritual energy to the demon thief's body again. During this time, he couldn't cultivate, but he could do other things, and he decided to use this time to integrate all the content in this forbidden formation method.

Time flies, and a year passes in the blink of an eye.

In the course of this year, Lin Sen had consumed a total of nearly forty Spirit Gathering Arrays, with a total of nearly five hundred mid-grade spirit stones, which enabled the Demon Thief to always maintain a glimmer of vitality.

Of course, for this huge consumption, if it weren't for the extremely abundant spirit stone resources, no one could afford to consume it. This is the reason why the best ghost spirit flower is extremely difficult to obtain.

In addition, during this period of time, Lin Sen's understanding of the forbidden formation has been greatly improved through the study of the way of the forbidden formation. The content contained in this book was almost integrated by him, but there were also some obscure formations that Lin Sen could not understand in a short period of time, no matter how much Lin Sen pondered.

The so-called prohibition is also a kind of formation. It's just that this spell is more flexible, and it can change depending on the caster's mind and thoughts, and in short, the ban is more inclined to divine thoughts.

For example, some great supernatural beings often set a ban when their divine thoughts move, and even after countless years, as long as their divine thoughts are not extinguished, the prohibition will still operate.

There are even prohibitions, even if the caster dies, the divine thoughts left behind will automatically form a new consciousness to maintain the operation of the prohibition.

This forbidden technique has some similarities with the hidden illusory technique that Lin Sen realized, or rather, the hidden illusory technique that Lin Sen performed is a kind of prohibition, but this forbidden technique is more complicated.

The method of prohibition is ever-changing, and few people can really and completely explore it thoroughly except for the caster, and there are two ways to break the ban. The simplest of them is to forcibly crack it, this method requires extremely strong cultivation, which is why Lin Sen's hidden illusion technique can be broken at will. The enemies that Lin Sen encountered were often several realms stronger than himself, and with such a large gap in cultivation, his forbidden technique could naturally be easily cracked.

The second method. That is research, and if you understand the production principles and rules of this prohibition to a certain extent, you can naturally crack it.

As said, if a person with insufficient cultivation fell into Lin Sen's hidden illusory technique, then unless he could find a way to crack it, he would be imprisoned forever.
