Hong Tu's divine sense has now locked on this group of demons, but he can't see any flaws in this group of demon formations, Snake Two and Wolf Three stood behind Hong Tu, and the two demon immortals looked at each other and laughed. Although the battle formation of this group of demons is a bit strange, Snake Two and Wolf Three can see that the core and weakness of the formation is the leader of this group of demons, the purple dwarf demon.

Snake Er stretched out his right hand and pointed a little at one point, and a cyan circle of light appeared in front of Hong Tu's body, which was obviously Snake Er using a circular light technique. A group of demons in the cyan aperture lined up in a special formation and stood motionless, exactly the same as the scene where Hongtu's divine consciousness swept over this group of demons, except that in this cyan aperture, the leader of this group of demons, the purple dwarf demon, had a red fork on the top of his head, which was a mark made by Snake Er for the weakness of this formation. In Hong Tu's divine sense, there was no red mark on the top of the purple dwarf demon's head, and when Hong Tu saw this red fork, he immediately understood the meaning of snake two, and the weakness of this formation was the purple dwarf demon.

Now that this group of demons has completed the arrangement of the battle array, if Hong Tu wants to break this battle array, he must start with the weakness of the battle array, that is, he must first kill the purple dwarf demon, so that the demon battle array can be destroyed. Although Hong Tu knew that the weakness of the demon battle array was the purple dwarf demon, he also understood that the purple dwarf demon was the center of this battle array, and its combat power was also the strongest, so if he wanted to destroy the center of this battle array, he had to fight the purple dwarf demon head-on, and the purple dwarf devil's combat power in the battle array was the strongest in the entire battle array.

This battle formation is only the most ordinary battle formation in the purple dwarf devil, but this battle formation has indeed been simplified after thousands of tempering, and it can be said that this battle formation has almost no weaknesses. Although the weakness of this battle formation is its center, it is guarded by the most powerful demon of the purple dwarf demon, and the enemy must fight the purple dwarf demon if he wants to break this battle array, so the powerful combat power of the purple dwarf demon makes up for the biggest weakness of the battle array.

After the purple dwarf demon set up the formation, he stood there and looked around, as if it was waiting for something. The purple dwarf devil understood in his heart that the feeling of palpitations just now suddenly appeared, it felt that someone was peeping, but it couldn't find the trace of the peeper, obviously the cultivation of this peeping person was above it, so the purple dwarf demon in the first time, it gathered all the demons together, arranged a formation and waited for this peeper to come.

After a group of demons stood in line, they all looked at the leader of the purple dwarf devil, their eyes were full of doubt, but none of the demons opened their mouths to ask the purple dwarf devil why they had gathered all the demons at this time. Because in the eyes of this group of demons, the purple dwarf demon is their leader, so as long as the purple dwarf demon gives an order, these ordinary demons will obey unconditionally, even if the purple dwarf demon sends them to death, these demons will complete the purple dwarf devil's order to the letter.

The purple dwarf demon is the leader of this group of demons, and he is also the highest-ranking demon among this group of demons, and the most powerful demon among them. These demons are members of the army of a large city in the Demon Realm, but they are not the guards of this big city, but the guards of a miner team of the Demon City Lord. The city lord of Castlevania is called Baba She, the general of this group of demons, this group of demons have followed Baba Tower to fight for many years, but they lost the war again, so they were sent by the city lord Baba Tower to a mine near Castlevania City as an overseer, their duty is to guard the weaker demons, and keep letting those weak demons dig ore for the city lord in the mine.

And the purple dwarf demon Fili is a centurion under the Castlevania lord Babata, where the war purple dwarf demon Philip did not complete the task according to Babata's orders in the battlefield, so Fili was sent by the Castlevania lord Babata's mine to be the leader of this group of demons. Life in the mine is very hard, Filip is the captain of the mine guard, and his life is much better than that of ordinary demons, but it is not very good, so it has some resentment towards the demon city lord Babata in its heart, it just did not complete the task once in the battlefield, and the city lord Babata sent it to such a place.

In the Whirlwind Mountain near the City of Sala in the Demon Realm, the Demon Fili was originally a ten-member under the lord of the City of Sala, Babata, but now he was sent to the Whirlwind Mountain by Babata. Although Whirlwind Mountain is near the City of Sala, the climate here is very different from the City of Salar, and there are huge whirlwinds hanging on the Mountain every day. Even if the purple dwarf demon is already an intermediate demon with the same combat power as a primordial infancy monk, but it is an overseer in the whirlwind mountain, but it can't walk in the whirlwind mountain at will, because once the strange whirlwind on the whirlwind mountain blows on the body, even the philip of the primordial infancy cultivation may be blown to death by this huge whirlwind, and the demons who can walk freely in the whirlwind mountain, except for the city lord of Sarah City, Babata, Filip has not seen other more powerful demons who can come and go here at will.

The miners of Whirlwind Mountain and the overseers like Fili, all of whom were transported by Babata, the city lord of Sarah City, with great mana, once these demons entered Whirlwind Mountain, it was impossible for them to leave Whirlwind Mountain without the cultivation of the Lord of Sarah. If it weren't for the abundance of rare ores here, Barbata, the lord of Sarah, would not have sent his men to the top of Whirlwind Mountain as overseers. Although there are many diehards of the Salar City Lord among these overseers, most of the demons have a grudge against the Salar City Lord, because entering the Whirlwind Mountain means that it is impossible to leave the Whirlwind Mountain for a lifetime, and only when the few diehards of the Salar City Lord are transporting ores, they have a chance to leave the Whirlwind Mountain, and the other demons don't think about going out when they get here.

Although Fili had heard of how hard life was on Whirlwind Mountain, he had never been to Whirlwind Mountain and couldn't imagine that life here was even more cruel than he imagined. There was a huge whirlwind blowing day and night on Whirlwind Mountain, and only at noon would the whirlwind become a little smaller, but with Fili's current cultivation, even if the whirlwind on Whirlwind Mountain was dozens of times weaker, he would not have a chance to leave Whirlwind Mountain. And every time the demon who transports the ore is set by the city lord Babata, after Filip enters the Whirlwind Mountain, just like the miners who have lived on the Whirlwind Mountain for decades and hundreds of years, he has no chance to leave the Whirlwind Mountain in this life, and the Huahua world outside makes Filip miss it incomparably.

It's just that now Fili has been sent to Whirlwind Mountain as an overseer by the steaming Babata of the City of Sala, and Fili knows that he will never be able to leave Whirlwind Mountain in his life. Because the perennial huge whirlwind on Whirlwind Mountain does not stop, and the magic power required for cultivation here is very weak, even if Filip gets a supreme cultivation book, it is impossible for Fili to cultivate to a higher realm without a large amount of magic support, let alone cultivate to a realm like the city lord Babata, so it is impossible for Fili to improve his strength and get out of Whirlwind Mountain by himself.

Among the miners on Whirlwind Mountain, there are many miners who were later captured by the city lord Babata, and there are also many demons who were born in Whirlwind Mountain, these beasts and demons in Whirlwind Mountain have only heard of the outside world of flowers, and they are very yearning for life outside Whirlwind Mountain, but they also know that they have no hope of leaving Whirlwind Mountain in their lives. Therefore, most of the demons on Whirlwind Mountain have a grudge against the city lord Babata, and the city lord Babata's knowledge of these situations.

However, Babata, the lord of Sarah's City, has never cared about the resentment of these demons, because there are countless demons who want to kill Barbata, the lord of Sarah, but Babata, the lord of Sarah, is not enjoying a good life in Sarah's City now. The resentment of these demons could not do any harm to Babata, although there have been many miners' riots on Whirlwind Mountain, and these miners have killed some of the overseers and Babata's cronies who are transporting ore, and they want to replace the overseers and the demons who transport the ore, so that the lord of the city, Babata, will release them from Whirlwind Mountain.

Every time the miners revolted, many demons died, but the organizers of the miners' revolt were all executed by the city lord Babata. The lord of Sara's City needs the ore of Whirlwind Mountain, but he doesn't care about the lives of these miner demons on Whirlwind Mountain, even if a few demons who transport ore die die, the city lord Babata, he can send new subordinates to help him transport the ore of Whirlwind Mountain. The ore produced by Whirlwind Mountain is called obsidian, although this ore contains a lot of magic power, but it cannot be directly used for cultivation, because the magic power in obsidian is very riotous, once a demon tries to absorb the magic power in obsidian, it will be hit to death by the magic power of the riot in obsidian.

Although obsidian cannot be directly used for cultivation, it is the best material for refining divine weapons, in the city of Salar a piece of obsidian about a kilogram can be exchanged for tens of thousands of medium-grade magic stones, and a medium-grade magic stone can be exchanged for 10,000 low-grade magic stones, but the magic stone is a trading item that can be directly used by demons for cultivation, that is, the currency in the demon world. Filip has been fighting under the Lord of Salar City for decades, and the wealth of his whole body is only a thousand medium-grade magic stones, which means that taking out a random piece of obsidian from Whirlwind Mountain can make Fili rich overnight in the demon world.
