"Chasing the Soul Butterfly and the Fall of the Taixia Great Wilderness" is a free-to-read article, the author's code name in the Mountain of Light is unknown, the article was published anonymously, Zhang Tie spent more than ten minutes carefully reading the article three times, and then the whole person pondered.

The Soul Chaser Butterfly is a strange species that lives in the abyss of the underground world, with very peculiar characteristics, if its eggs are captured, then, as long as it is a knight-level person, after the egg hatches, as long as he feeds his own blood to the Soul Chaser Butterfly a little, the Soul Chaser Butterfly will establish a wonderful spiritual connection with the knight who feeds its blood, and can accept the knight's command to help the knight find or lock someone.

A person in a certain area and space activities, will leave their own smell, trained hunting dogs and military dogs will be easy to identify these smells, so as to find these smells to find the owner of the smell, these smells, is a person's body emitted, but in addition to this smell, a person's body, in fact, there is another invisible smell, this smell, from a person's inner characteristics, is a person's spiritual power or soul emitted by the "smell", And the most powerful thing about the soul chasing butterfly is that this creature can sense this invisible "smell" on a person's body like a hunting dog, so as to find out a person through this "smell".

This is where the Soul Chaser Butterfly is most valuable.

Countless studies have confirmed that as long as a person has been in a certain place, even if that person then leaves, within 72 hours. The "soul smell" left by that person in that place will not dissipate, put a soul chasing spirit butterfly and turn around the place where that person stayed, and the soul chasing spirit butterfly can accurately identify that person's "soul smell" and remember it firmly. Then within a range of 300 kilometers, you can accurately sense the direction of that person.

Zhang Tie memorized the two key numbers of chasing the soul butterfly - 3 days and 300 kilometers.

Of course, these two numbers jù are only approximate numbers, they are a reference number jù, in fact, there may be a slight error due to the individual differences of the soul chasing spirit butterfly, but the disparity will not be too large, for example, some soul chasing spirit butterflies can sense the target at a distance of more than 310 kilometers, while some soul chasing spirit butterflies may only have a sensing range of more than 290 kilometers. Some Soul Chasers may be able to recognize the person's "soul scent" in that place 74 hours after a person leaves that place, while some Soul Chaser butterflies may no longer be able to identify the "soul scent" that locks on that person after 65 hours after a person leaves a certain place, which is normal.

According to the speculation put forward by Beishan Yun in the article "Soul Chasing Spirit Butterfly and the Fall of the Taixia Great Wilderness Gate". There may be two reasons for the connection between the fall of the Great Wilderness Gate and the Soul Chasing Spirit Butterfly, one is that legend has it that an elder of the Great Wilderness Gate went deep into the underground abyss at that time and used the technique of soul control to control a mutated Soul Chasing Spirit Butterfly, which was compared to an ordinary Soul Chasing Spirit Butterfly. Not only does it have a long lifespan. Moreover, its ability to chase souls can be called terrifying, more than twenty times stronger than ordinary soul chasing spirit butterflies. After getting that Soul Chaser Spirit Butterfly, the elder of the Great Wilderness Gate used the mutated Soul Chaser Spirit Butterfly he controlled to cooperate with others, and did several big things, which made him famous for a while, but at the same time, he also offended some powerful forces in Taixia because of those "big things", and in the end, those forces joined forces. led to the fall of the Great Wilderness Gate.

The second reason is that the Soul Chaser Butterfly can distinguish the soul scent of all people. But only the Great Wilderness Gate's Soul Control Beast Secret Method is helpless, and the Soul Chasing Spirit Butterfly can't distinguish and lock the animals that are entrusted to the soul, in the second holy war, the people of the Great Wilderness Gate used the Soul Control Beast Technique to go deep into the control area of the Demon Race, spying on a lot of key intelligence, and destroying many actions of the Demon Race, it is precisely because of this that the Great Wilderness Gate is taboo for the Demon Race and the Three-Eyed Society, so it was destroyed under the combination of the Demon Race and the Three-Eyed Society.

In all fairness, the gossip atmosphere of this article is too strong, and the two connections between the fall of the Great Wilderness Gate and the soul chasing spirit butterfly are somewhat far-fetched, and some details cannot withstand too detailed scrutiny, but this article is very useful to Zhang Tie, because it tells Zhang Tie the two pieces of information that Zhang Tie wants to know most at the moment - what is the ability of the soul chasing spirit butterfly? Will he be discovered by the Soul Chaser Butterfly in the state of the Soul Riding Beast?

What Zhang Tie was thinking about was that if there was more than one Soul Chasing Spirit Butterfly egg in the Demon Shuai's hand, what would he do in the future? Unless he hides in the Black Iron Castle for 60 days every time he acts, otherwise, as long as he reveals his true self outside, the possibility of encountering the Demon Marshal or being surrounded by other knights will be greatly increased - today the Demon Shuai used a Soul Chasing Spirit Butterfly to hunt him down, and he knows that the Soul Chaser Soul Butterfly that will hunt him down in the future will not be three, or even five. As long as there are more than three soul chasing spirit butterflies chasing themselves, then as long as each group of knights holds a soul chasing spirit butterfly in their hands, the width of their search sensing range is 1800 kilometers, and when they reach this distance, the three groups of knights don't even need to do anything, they just need to unify the action time and fly in a straight line in the entire northern demon occupation area, as soon as they reveal their deity, they will be locked by the demon knights immediately, and the danger they will face will increase dozens of times and hundreds of times.

Even if you can use your avatar to leave or hide directly in the Black Iron Castle at a dangerous moment, it will also have a price, and the price will be the exposure of your own secrets, and once your secrets are exposed, the trouble it will bring may be the real endless trouble.

Nothing comes without any price, the emperor has a price for eating in a restaurant, a handsome guy has a price for finding a woman in a brothel, and even if he owns the Black Iron Fortress and goes behind enemy lines, there is also a price.

At this time, Zhang Tie had already thought of leaving, wanted to Mingjin to withdraw his troops, and retreated, to be honest, this time he went deep behind the enemy, and he was able to achieve such a result, which was already very impressive - he almost destroyed and severely damaged the two cities of the Demon Clan and the Three Eyes Society, killed more than a dozen precious tomb tower demons and a knight master, and at the same time delayed and disrupted the action plan of the Demon Clan and the Three Eyes Society.

But for some reason, what involuntarily appeared in Zhang Tie's mind at this time was the pair of swollen and pus-draining feet that he had just seen stepping on in the cold and damp mud and the scene of the owner of those feet finally falling to the ground and being eaten by the demonized puppet.

What should I do at this time to make my mother and father feel proud and gratified?

Whenever it was difficult to choose, Zhang Tie would ask himself this question......

When Zhang Tie tortured his heart over and over again with this question, the final decision slowly surfaced in Zhang Tie's heart, making his eyes firm again...... (To be continued......)
