What Roy didn't know was that Walgreens had been waiting for Walgreens for a long time before he found the four-winged angel leader!

He was waiting for the angelic leader to die......

No way, although Walgreens is a superior demon, he doesn't seem to like fighting, or rather, he is too good at fighting, when he noticed that there was a seriously injured angel leader here, he didn't immediately pounce and lose the other party's life and take away the other party's soul, but chose the safest one and waited for the other party to die.

And he waited from afar, so he could be said to be timid and cautious to the extreme......

However, what Walgreens didn't expect was that at this time, Roy swam over, and immediately found the angelic leader buried in the rubble, and dug it up.

Walgreens had the feeling that a duck had flown away, but he would never have done anything to get him to stand up and fight Roy for the ownership of the soul of this angelic rule!

So after thinking about it, he still did his old job, appeared behind Roy, and planned to make a deal with him.

Hearing him say this, Roy also suddenly understood, so he forcefully pinched off the neck of the Angel Leader that he was carrying, and then held the golden soul floating out of the Angel Leader's body in his hand, stretched it out in front of Walgreens, and said, "You want to trade with me, is this it?" ”

"Aha! The Holy Soul of the Four-Winged Lord Angel! Walgreens looked at the soul greedily and stretched out his claws to get it, but Roy suddenly withdrew his hand, leaving Walgreens scratched the air!

This golden angel soul is a "medium divine soul" in the system's display! It was different from the souls of those low-level angelic soldiers, so Roy also realized that this soul might be considered more precious, how could Walgreens get it so easily?

Looking at Roy's playful eyes, Walgreens also reacted, pretending to cough to hide his embarrassment, and then pointed to the corpse of the angel leader and said, "There is also the angel core, and I want the angel core too!" ”

Roy glanced at him, didn't speak, and as soon as he stretched out his hand, the sharp claws broke open the lower abdomen of the angelic leader, and from his abdomen, pulled out a small, crystal-like object, and its surface had a lot of dense angelic writing.

This is the angel core, from Alanya's memory inheritance, Roy knows that there are some angels who have such things, but even in the memory inheritance, there is no mention of what this angel core does, so the angel soldiers that Roy killed before, he only took away the soul, but did not touch the angel core in the other party's corpse.

"You know what this thing does?" Roy asked Walgreens.

"Of course!" Walgreens rubbed his hands together and said, "I'm a Rift Demon, and thanks to the spatial abilities I have, I know a lot of secrets!" ”

"Explain it to me!" Roy tossed the angelic core in his hand.

"You probably don't know...... There are some angels that are artificially made! Walgreens' gaze rose and fell with the tossing of the angel's core, and his mouth explained endlessly: "Angels are creatures, although they are more powerful than demons, but their fertility rate is very low!" There are very few primordial angels that can actually be born from angel eggs, so the Heaven Foundry has been working on artificial angels in addition to crafting weapons and armor, so that it can recover the numerical disadvantage in the war with demons! ”

"Oh!?" Roy was stunned for a while, looked at the angel core in his hand, and said, "So, those who have such things as angel cores are all artificial angels?" ”

"That's right!" Walgreens nodded: "They first cultivated an angel embryo, and then implanted it into an angelic core to carry the soul, and then transformed the collected noble soul into a holy soul under the action of holy power, and then put it into the angelic core, and an artificial angel with its own power and memory was born, which is a method of mass production of angels!" If it weren't for the small number of noble souls that could not create too many artificial angels, perhaps the situation between demons and angels would have been reversed in the war......"

Roy was a little stunned when he heard this, no wonder he always felt that the equipment on the angel side looked much better, and the Heaven of the Dare Lovers was also developing scientific research power, not only that, but they even had artificial angels......

However, this kind of technology should be more on the occult side, right? After all, this angelic core looks more like some kind of alchemy item......

"What is the use of this angelic core? Used to create fallen angels? Roy asked.

"No, no, an artificial angel cannot be a fallen angel!" Walgreens shook his head and said, "Only the primordial angels, that is, the angels born naturally, can be transformed into fallen angels!" The soul is a thing, containing the driving force of all things, only a body without a soul, it is just a puppet, only with both a body and a soul, can it form consciousness and will, and become a real life, so in fact, this angelic core is just a container used to load and restrain the soul, after losing the soul, this container is useless, and the only value it has left is for research...... Well, maybe it can also be used as some kind of good alchemy material! ”

Roy thought about it for a moment and felt that Walgreens might not be lying, but he should have hidden something as well, such as how precious this angelic core was......

So, Roy grinned at Greenwall and said, "Yes, since it's useless, then I'll keep it for myself!" It should be nice to make an accessory or something, right? ”

"Uh......" As soon as he heard Roy's words, Walgreens was suddenly embarrassed, he didn't expect that he tried his best to belittle this angel core, but Roy choked on a word.

That's right, the angel core is actually not very useful, but that refers to the core of those low-level artificial angel soldiers, and the angel core that Roy got right now was obtained from a four-winged main angel, and the artificial angel can be promoted to the level of the four-winged, but it is not easy, which means that this four-winged angel may be an earlier batch of artificial angels, who have been alive for a long period of time, and have not been expelled to heaven because of death, resulting in a replacement of the body.

In this way, the research value of this angel core has naturally increased greatly, and it is far from being comparable to that of ordinary angel cores......

"Okay!" Walgreens found himself in the pit, so he spread his hands and said, "I admit, this angel core is very precious, so what price do I have to pay to get him?" ”

"What do you have?" Roy asked, expectantly.

He knew very well that the demon profiteer in front of him had a lot of good things in his hands, and with the spatial ability to come and go freely, he was able to reach many places that demons could not reach, so as to collect some special things, and this guy had no position, he could trade with anyone, even if it was the Four Horsemen of the Apocalypse or Angels.

Roy hadn't thought of meeting this guy before, but since he had met him, he couldn't let it go, even if he didn't have the soul and angel core of this four-winged angel, he planned to trade with Walgreens once, after all, Walgreens also accepted souls as currency, and in the past trading process, he may have hoarded a large number of souls......

However, Walgreens did not offer to trade with Roy with his soul at the beginning, but with a wave of his hands, he showed an item in front of him and said to Roy: "You are in the process of being promoted now, and your body seems to be changing, I think you may be able to use this thing......"

Roy looked down, only to see that what Walgreens was showing was actually a ...... Kettle!?

"Are you sure you didn't take the wrong thing?" Roy asked him with a glare.

"Absolutely! This is something I managed to steal from under the nose of Azrael, the Angel of Death! Walgreens said with a slight smugness: "This is the well water from the well of the soul!" ”

Roy gave him a suspicious look and asked, "Okay, let's just say it's true, but what's the use of this thing?" ”

"Hah, this thing does a lot of things!" Walgreens waved his hand and gestured, "But its greatest effect is to purify and strengthen your soul!" ”
