That dangerous demon Qi was dense and stifling, even some high-level demon cultivators would have trouble holding it. However, for this demon cultivator who was a peak of the late peak Heavenly God Realm and above, demonic devil qi was still bearable.
Moreover, to old demons with high cultivation, this dangerous demon qi was actually a treasure. If they could stay and cultivate within this Demon Cave for a hundred years, it would definitely be comparable to their increase in a thousand years outside.
As Zhang En flew deeper into the cave, he constantly circulated the ferociousness of the demon god dragon, pulling the surrounding demon qi into his body, purifying it and absorbing it.
Inwardly Zhang En was delighted after absorbing that dangerous demon qi for quite some time, as he discovered that this demon qi also contained the demon qi of the Thousand Soul King.
Right at this moment, Shan Hai who had been flying in front suddenly stopped and turned his sharp gaze towards Zhang En.
"Wu Zhi, come here," Shan Hai said.
Zhang En's heart stiffened, was this man nicknamed Demon God looking at him?
However, Zhang En had no choice but to step forward, saluting, "Devil God Master."
"I heard that some time ago you obtained the Demon Emperor Book?" Demon God Shan Hai asked.
Zhang En quietly breathed a sigh of relief hearing this.
"This branch did find the Demon Emperor Book some time ago, just waiting for the opening day of the Demon Cave to offer it to Lord God Ibis."
Then, Zhang En took out a square black metal token that emitted a soft golden light.
The Book of Demon Emperors was embedded within this black metal token.
On the day he killed Wu Zhi, he found this Book inside his spatial ring.
Shan Hai's hand sucked the black square metal into his hand and used his spirit sense to examine it, smiling at Zhang En, “Not bad, it really is the Book of Emperor Ibis. When you return from here, come to the Devil Valley, you can cultivate in the Demon Pond for a few months. ”
The other sect patriarch revealed an envious look at Zhang En hearing this.
Zhang En quickly showed his gratitude.
“Alright now, everyone part ways and look for treasure. When we leave, I will judge you based on the number of Demon Crystals you have collected.” Shan Hai said to everyone.
Inside this Demon Cave, other than the Demon Crystals, there were several other treasures. This was also one of the reasons why the four great leaders of the World Demon Kingdom would lead a group of people every time they entered.
Every time they opened the sealing formation of the Demon Cave, it would only remain open for ten days.
On Shan Hai's orders all acknowledged respectfully, the excitement in their hearts as they went in different directions.
“Wu Zhi is quite ambitious, cultivating in secret after obtaining the Demon Emperor Book. Today, if not for Master Shan Hai asking him this matter, he would not have given up the Book.” One of the Elders stared coldly at the figure of Zhang En who was leaving.
Shan Hai nodded in agreement, “The most important task right now is to look for the Demon Crystals. Wait until he comes to the Devil Valley, I will personally deal with him. My Ghost Flag just lost a few corpses of demon cultivators. ”
Shan Hai and those elders disappeared from his place in an instant.
After Shan Hai's group left, the place where they were standing before rippled as Zhang En's figure appeared.
Zhang En looked coldly at the direction where Shan Hai's group was going, sneering, 'This old devil, each one of them is extremely ruthless.'
Zhang En then flew towards the deeper parts of the cave, following in the footsteps of the demon qi.
Other than treasures, the cave was also filled with demonic creatures. Especially in the deeper parts, some of the more powerful demon beasts were comparable to a One Star Golden God, and some were even as powerful as a Two Star Gold God.
Therefore, Zhang En did not dare to be rash despite having faith in his own strength.
As he flew towards the deeper part of the Demon Cave, a sharp sword qi suddenly pierced through the air, blocking Zhang En's path.
SWOOSSHHH!!!
SWOOSSHHH!!!
Two people appeared in front of him, one of them was Mu Sen and an old man with protruding arms.
“Wu Zhi! Today, the Demon Cave will be your burial place!” Mu Sen gnashed his teeth, a sword forged from the bones of an earth dragon appeared in his hand, pointing towards Zhang En.
Zhang En looked at the two people blocking his path nonchalantly, "You can still survive if you escape now."
Mu Sen and the old man were dumbfounded, then laughed out loud.
“Wu Zhi, what did you just say? My ears didn't hear me wrong, did they?” The old man laughed, "You think you're a Golden God?"
Zhang En shook his head, he could not be bothered to waste any more time. With a wave of his hand, the old man was pulled towards him. Zhang En's fingers clenched and the old man exploded.
DUAARR!!!
Mu Sen was surprised to see this. As fear crept into his eyes, he turned around and tried to escape.
Looking at Mu Sen, a wisp of fire energy shot out from Zhang En's finger, piercing through his back in an instant.
WUUZHI!!
Starting from Mu Sen's chest, flames began to spread outward, reaching his four limbs in less than a single breath, burning him to ashes.
Zhang En did not stay there for long, continuing to fly deeper into the cave.
The Demon Cave only opened for ten days, and he needed to find the body parts of the Thousand Soul King, subdue him, and take him away in no time. Otherwise, after ten days had passed and Shan Hai and the others left the Demon Cave, he would not have been able to leave the cave for a thousand years.
One day later, after killing several hundred demon beasts, Zhang En finally arrived at the deepest part of the Demon Cave. Here, the demon qi was at its densest point, forming a dark green yin cloud. Those dark green clouds emitted an invisible force that greatly suppressed one's soul, even a Gold God would not have an easy time surviving.
As Zhang En went deeper into that cloud Qi, his face looked increasingly gloomy. Stopping on a rock, he performed the Blood Sacrifice Technician with a drop of his blood essence, dropping it to the ground.
Almost immediately, a strange energy fluctuation came from below.
Zhang En's eyes shone with excitement, entering into the ground until he reached the source of the strange fluctuation.
Soon, he reached the familiar cave that sealed the body of the Thousand Soul King
The moment Zhang En entered the underground cavern, the Four Demonic Kingdom World Experts, Muan Ji, Shan Hai, Mu Shi, and Yang Han arrived at the deepest region of the cave, all of them being in the cave, because Demon Crystals always appear somewhere in the deepest part of the Cave.
