"How...... How is it possible, there are at least five hundred Praetorian Guard soldiers stationed in the Praetorian Guard camp near here, as well as a few mid-level magicians, how can they all die here?" Arnold obviously didn't believe Wang Xu's judgment, but as he spoke, his tone became lower and lower, and his confidence became weaker and weaker, obviously, he realized that he couldn't explain where the heads hanging around the totem pole came from.

"Five hundred Praetorian Guards, I took a look, there are about one or two hundred totem poles around here, each totem pole has at least two heads hanging on it, and some totem poles even have five hanging on them, so it can be seen that the number of elves who died here is at least more than five hundred. Although he didn't want to describe the death of his compatriots, in order to clarify the basis for his judgment, Wang Xu still explained.

"Well, he's right," Zana looked at Arnold, the head of the mercenary group, and added in a deep voice: "You just said that the reliefs on those armor and shields are the military emblems of the Praetorian Guards, so the identity of the deceased can be completely determined, it is the Praetorian Guards in the nearby military camp, as for whether the Praetorian Guards in that camp are all dead as he said, I can't judge." ”

"Hmm......" Arnold snapped with a pale face and wandering eyes, although emotionally, he didn't want to believe that the dead here were soldiers of the Praetorian Guard, but his reason told him that Wang Xu was right.

"Is there a camp for the Praetorian Guards around here?" Wang Xu suddenly asked Arnold.

"Well......" Arnold was taken aback by Wang Xu's sudden question, and after a moment of froze, he replied, "Yes, five kilometers to the west and five kilometers to the east, there is also a camp of the Janissaries. ”

Arnold is not a person without experience, who answers whatever others ask, the reason why he trusts Wang Xu is not only because Wang Xu is a half-elf with purple eyes, but also because of Nilou's relationship, no matter how you look at it, Nilou is a pure elf nobleman, since the elf nobleman Nilou is a woman of half-elf Wang Xu, then, Wang Xu cannot be an outsider, it is worth believing.

"Do you think ......" Nilou, who was already angry, seemed to guess the purpose of Wang Xu's question after listening to Arnold's answer, and in an instant, the anger on her face became even stronger, and even a worried look flashed in her eyes.

"That's right, I suspect that all the Praetorian Guard camps on the edge of the forest may have been raided by the orc forces at the same time, and the rest of the camps should be as miserable as this one," Wang Xu continued in a deep voice with a solemn face: "In other words, the first line of defense on the periphery of the Elven Forest has been completely broken through unconsciously. ”

"This ...... It's impossible," Arnold didn't believe that the orc tribe could really wipe out the first Praetorian Guard defense line at the edge of the forest at the same time, although he didn't know how many Praetorian Guard camps there were on the periphery of the Elven Forest, but, judging from what he had observed during this time, there were three or four hundred, "The strength of the Praetorian Guard is still very strong, and ordinary soldiers have the strength of junior swordsmen at worst, and they are not so easy to be eliminated!"

"I hope the situation is as you say," sighed, Wang Xu casually released a large psychic paper crane, and then, the psychic paper crane flapped its wings violently, and flew straight into the sky rapidly, and after less than ten seconds, it flew to a height of more than 1,000 meters, looking down at the surrounding forest within ten kilometers, "Hey!"

"What's wrong?" Arnold asked Wang Xu worriedly.

"The two Praetorian Guard garrisons in the east and west directions have also been breached, and there are also sacrifices like here!" Wang Xu shook his head slightly to express regret.

"What! sacrifice!" exclaimed not only Arnold, but also Nilou and Zana.

"That's right," Wang Xu took out a snow-white blank scroll from the backpack system with a gloomy face, and then took out a paintbrush, and then, looking at the pebble circle in the center of the area surrounded by the totem pole, he drew it on the scroll without distinction, "Look. ”

After Nilou and Arnold had seen it, Wang Xu continued: "Although I haven't understood the overall operation of this circle, you see, part of this circle is a space circle, and part of it is a summoning circle. ”

"Well, that's right!" Zhana, who had studied the magic circle quite a bit, frowned and nodded slightly in response to Wang Xu's words, which proved that Wang Xu's judgment was reasonable.

"From what space can this circle summon something?" Arnold asked, his voice trembling.

"I don't know, according to the scene described in the ancient books I have read in the past, if this kind of sacrificial circle wants to summon something, it depends on how many souls are sacrificed and the quality of the souls. Wang Xu whispered his guess.

"I remember that the sacrificial sorcery of the orc wizards had long since been rejected by the gods and erased from the world, so why did this evil art appear again?" Nilou asked the king in a crisp voice.

"The demon clan still has this kind of witchcraft that is no less than a forbidden spell, in order to buy off the various orc tribes, if you don't come up with something good, can you succeed, but even I didn't expect that the demon clan's bargaining chip turned out to be a long-lost sacrificial witchcraft!" Wang Xu shook his head slightly and sighed.

"The souls of all the dead elves have disappeared, is this the effect of sacrificial witchcraft?" Saint Zana, the necromancer who knows all about souls, raised her hand and pointed to an elf head hanging on a totem pole, a puff of black smoke flew out of her palm, and the black smoke flew into the mouth of the skull, and after a long time, the skull did not react at all.

"Well, maybe, although I don't know the specifics of sacrificial witchcraft, but, you see," Wang Xu raised the scroll in his left hand and pointed to the upper left corner of the sacrificial circle with the tip of the brush he was holding in his right hand, "This part of the circle is related to the soul, and I don't know what it has to do with it." ”

"That's the Transformation Circle, the function is to transform the soul into pure dark energy," Zana suddenly said in a deep voice, "My 'Black Book of the Dead' records a part of this magic circle, don't believe it, you see. ”

Zana took out the "Black Book of the Dead" with a little excitement, and opened one of the pages, on which was a mutilated magic circle, which was very similar to the pattern in the upper left corner of the magic circle drawn on Wang Xu's scroll.

"Well, yes, it's very similar, and it looks like it won't be long before the two of us figure out how this circle works. Wang Xu nodded slightly and replied to Zhana in a low voice.

"Now isn't the time to talk about this, don't you want to know what has been summoned in these circles?" Nilou interrupted Wang Xu and Zana about the soul circle, and steered the conversation back to the right path.

Before Nilou could finish speaking, she heard a loud roar not far away, and the roar swept a whirlwind from the depths of the forest, uprooting many small trees.

"Don't be curious," Wang Xu said with a wry smile, "It's coming......" (To be continued.) )
