From the night battle to the dawn, the endless Shura and demon beasts came one after another, killing endlessly, the spiritual power of the monks who rushed to kill the main force had long been exhausted, and the reserve monks alternated three or two times to barely maintain the battle line, and they were not defeated by Shura, but the number of dead and wounded was more than double that of the previous days combined, and there were broken limbs, broken flesh and pools of blood everywhere.

In order to prevent Shura from snatching and devouring his body, once a monk falls into a heavy siege, most people will choose to blow themselves up before losing their divine sense, besieging the eight major sectors of the demon fog, and there are constantly bright lights rising into the sky, making the remaining monks have their blood and blood, gritting their teeth and fighting with Shura and demon beasts.

From dawn to dusk, Shura gradually became scarce, Yi Xuan let the brave and good iron guards continue to stand on the front line, and the rest of the monks all retreated to the station to rest and recover, all of them were covered with blood and collapsed to the ground from exhaustion.

Yi Xuan patrolled the station for a week, and secretly complained in his heart, originally according to his own guess, the demon fog should not have such a violent reaction, and what intention did the sudden increase in counterattack represent the heavenly demon, he was puzzled, and his heart was as if he was pressing a boulder.

Yi Xuan paced around the station, thinking about the hidden mystery in the magic mist, and Ah Yi ran to tell the news: "Leader, now only sporadic Shura is still resisting, I will leave twenty squads to hunt and kill, and the rest will all return to the station for repair, and there are also a thousand monks from the Amaterasu Sect patrolling, which will definitely ensure that the station is safe and sound." ”

Yi Xuan saw that Ah Yi's face couldn't hide the tiredness, but his body was still straight, and he was relieved: "Thanks to you good brothers! Ah Yi, how many Shura have you killed today?"

Ah Yi smiled innocently, scratched the back of his head and said: "Leader, I didn't rush to kill, but I have to pay attention to the safety of the Iron Guard squads at will, only when the middle and high-level Shura appear, I will shoot quickly, so the number of enemies killed is not much, only dozens of Shura." ”

"Very good, Ah Yi is no longer the fierce general who was brave and brave at the beginning, and has become a general who stands alone. How many Shuras did the entire Iron Guard kill?" Yi Xuan was very satisfied with Ah Yi and turned to ask about the results of the Iron Guard.

Ah Yi showed a proud look on his face: "These boys didn't embarrass the leader, they all killed you with red eyes, the least team also killed hundreds of Shura, the most teams were thousands of people, and a few boys actually broke through the battle." It is also strange to say that in peacetime with hostile battles, there are very few people who can hold on to the iron guard for a long time without being defeated, and these Shura are completely fearless of death, no matter how many companions are killed or injured, they do not have any sense of fear, they are just a group of walking corpses without souls. ”

"There are no souls...... The Walking Dead ......" The last few words Ah Yi said made Yi Xuan stunned at once, and he looked at him for a long time, making Ah Yi think that Yi Xuan had been hurt in the battle.

Yi Xuan finally connected several important clues in his mind, and came to a new inference: the extraterritorial heavenly demon could not be killed, and could only be sealed through the formation, and it could be deduced that the demon soul of the heavenly demon was far stronger and stronger, so it was not easy to be killed; 。 ”

"Oh no! I'm waiting here to fight Shura, with countless casualties, isn't it just to speed up the recovery of the Heavenly Demon. No, you have to hurry up and inform the Hundred Flowers Dao Venerable to know!" Yi Xuan hurriedly explained a few words to Ah Yi, flew to the Zuoqiu station, and found the Great Elder to explain his intentions.

The two of them interrogated through the bronze mirror and the Hundred Flowers Daozun, but they were suspicious when they heard it, after all, Yi Xuan would say that he would speed up the attack, and he would say that as long as there were casualties in the battle with Shura, it would help the Heavenly Demon recover.

"That's good, Dao Zun can have any magic weapon to sense souls, as long as we hand it over to a special person on the battlefield to monitor and see if the soul of the dead monk has escaped into reincarnation or is collected by the Heavenly Demon!" Yi Xuan saw that he was hesitant and said a way to judge.

Baihua Daozun replied: "There is no need for any magic weapons, those Demon Venerable old ghosts have many subordinates who are proficient in soul refining, let them pay close attention to what Yi Xuan said." ”

After ending the communication with the Hundred Flowers Dao Venerable, Yi Xuan returned to the station with mixed feelings, the strange behavior of these Shura made him a little uncertain, he didn't know how to judge at all, and he didn't even have the interest to continue to comprehend the runes. Suddenly remembered that Xiao Zhong had taught him the method of extracting the soul of the demon beast, and thought that Dayan Tianzun had also studied the theory of the soul, and when he returned to the camp, he couldn't wait to ask Xiao Zhong.

"Collecting souls are all some demon gate techniques, and in the past, Dayan Tianzun did collect and learn some of them in order to create exercises, but it can't be said to be a profound study. However, your requirements are very simple, you only need to monitor the whereabouts of the souls of the dead monks, you can set up a soul altar to collect the souls of the living who have just passed away within a hundred miles, and the presiding officer of the altar can clearly detect the whereabouts of the souls to achieve the purpose of monitoring. Xiao Zhong solved Yi Xuan's problem.

But before Yi Xuan could start arranging, he was stopped by Xiao Zhong: "This soul conjuring altar is a notorious magic cultivation method, which is despised by the Immortal Sect, you have to think about it, how to explain it if someone finds out!"

"The situation is urgent, I can't take care of so much, if I am unfortunately said, not only will none of the monks here be spared, but even the real cultivation realm will die at the hands of the Heavenly Demon. Yi Xuan didn't have time to think too much, Xiang Xiao Zhong asked for the sacrificial refining technique of the Soul Conjuring Altar, and hurriedly came outside the station.

Simply arranging a phantom array to isolate the hearing and hearing, Yi Xuan used mana to condense the soil and build a three-foot high platform, after a day of bloody battle, the soil was full of broken flesh and blood clots, which just met the requirements of the conjuring altar, a small altar mottled with blood stains was completed in a snap of his fingers, and then the most important refining of the conjuring flag.

To set up six soul flags on the altar according to the six-pointed star array, this soul banner also needs yin and evil and filthy things, Yi Xuan endured the discomfort and took materials on the spot, and still used the stump flesh and blood that had not been cleaned on the battlefield, and casually refined six low-level soul flags and placed them in the corresponding position of the altar.

The Conjuring Altar suddenly emitted a black spiritual light, and the surrounding environment suddenly lost its color in Yi Xuan's eyes, leaving only black and white, and through the phantom array, it could be seen that the monks in the distance were all white points of light, and the points of light were strong and weak in relation to cultivation.

During the daytime battle, the Great Righteous Sect and the Zuoqiu family suffered thousands of casualties, even if most of them would even have their souls turned into nothing after the self-explosion, there should still be a small number of remnant souls that stayed in place and had not yet dissipated, but at this time, the battlefield in front of Yi Xuan was pitch black, and there was no trace of any soul.
