Jia Zhengjin didn't pay attention to Brian's rambling in his ear, and just carefully examined the loot.

【Demon Altar Construction Blueprint】Build a mysterious altar that can summon demons to serve you, but you must sacrifice living creatures as sacrifices for each summoning! You have to beware of the Church of Light, once they find out, they will fight with you endlessly! Materials required for construction: 1 demon heart, 1 bottle of demon blood, 1 book of demon summoning, 20 skulls of the dead.

This is also a building similar to the Barracks, where you can summon new troops. And it seems that the materials are already available here, and they can be built directly! It's just that every time you summon you have to sacrifice a living thing, does that mean you want a living person? Or is it anything as long as it's a living creature?

Besides, if the construction of the Demon Altar is discovered by the Church of Light, they will have to fight with themselves endlessly? That would be a big trouble! After all, one of Jia Zhengjin's three wives, Christina, is the ascetic priest of the Church of Light. Her teacher is a more powerful existence in the Church of Light, and she plans to use her husband and wife relationship with Christina to enlist her teacher Devara Leo to help her, and even be able to get the Church of Light to cooperate with her!

But summon demons! The half-finished product that has not yet completely turned into a demon, and the strength of a mere demonic creature is so strong, if it can summon a complete demon, how powerful will it be? If it summons a demon army, what kind of terrifying combat power should it be?

This made Jia Zhengjin quite entangled, and it was difficult to decide for a while.

So he put the question aside for the time being, and took a closer look at the other loot.

【Book of Demon Summoning】+5 Intelligence, after killing any living being, you can bind their soul to this book. When the soul accumulates to a certain level, you can summon the terrible demon lord and let him grant a wish for you!(System Tips: Don't believe the words of demons, they will do everything to deceive you and take away your soul!)

Seeing the introduction of this book, Jia Zhengjin couldn't help but twitch the corners of his mouth. Just looking at the previous words, he really can't help but try and see if he can fulfill any wish. But when I saw the system prompt behind, I immediately dispelled the idea.

He remembered the murdered Rags, maybe he accidentally got the Book of Demon Summoning when he was imprisoned, and then used the summoned little demon to lure and hunt his brother, and then even his brother's family and subordinates did not let go, just to fulfill a wish. But it is estimated that he was fooled by the devil, and then he turned himself into a demonized creature that is not a human or a ghost. Even after gathering enough sacrifices, they may fall into the new demons!

This book is too dangerous, so let's keep it for now!

Demon hearts and demon blood are the materials used to build the Demon Altar, which is nothing to say about as there are no other uses for it.

【Demon Certificate】With this card, you can enter the underworld as a demon. Find the entrance to the underworld and show it to the demon guards!

The underworld, the land of the devil, who would go to that kind of place when they were full?

Jia Zhengjin put away his documents and shook his head, a demon that has not yet taken shape is so terrifying, the underworld is full of terrifying demons whose strength exceeds his ten, hundred, or even a thousand times, it is very easy to find death there.

The horns of the little devil, the claws of the little devil, and the scales of the little devil are all alchemy materials, and they are all stored in the backpack for the time being, and they may be used in the future.

【Fire Aversion Enchantment Skill Book】After using it, learn the fire aversion enchantment magic to create a vacuum in an area where the fire elemental elves cannot survive. Fire magic will no longer work in this area!

Isn't that a fire magician, as long as he sets up an enchantment, no matter how good his skills are, he will be abolished immediately? It's a pity that Jia Zhengjin can't learn the skills of the magic department himself, and it seems that he can only let Tina learn it!

But fortunately, the husband and wife have learned the same, such a strong skill, so useful!

Anyway, Connie's pit is a fire-based dragon, right? If there is a fire-weary enchantment, wouldn't Connie be able to use magic and let herself be bullied?

As soon as the thought comes together, immediately dismiss it.

Stupid or not? Even if a dragon doesn't use magic, it's still a dragon! People swallow you in one bite, do you need to be so troublesome?

However, this magic is really powerful, and Jia Zhengjin has already experienced it himself. Even the torches made by the system were quickly extinguished, which was really fatal for the fire magician!

After counting the loot, although Jia Zhengjin felt disgusted, he still collected the skulls that were rolling down on the edge of the destroyed altar and put them in the virtual backpack.

The Skull Candle ignites a demonic fire that cannot be extinguished.

Demon fire? It seems that it has nothing to do with the fire elemental spirits, so it's no wonder that it can be burned and illuminated under the fire-weary barrier.

After confirming that there was nothing else and no other way out, Jia Zhengjin came to his senses and removed the hallucinogenic insect from the corpse of the one-horned demon.

At this moment, the hallucinogenic insect has become pitch black because it has absorbed a lot of black blood, and its attributes seem to have changed, and its name has become [Hallucinogenic Demon Worm]!

Jia Zhengjin thought that the bloodsucking worm had sucked the demon's blood and might die. But I didn't expect that not only did it not die, but the species changed!

Anyway, this should be a good thing for you! Although I don't know what the difference between hallucinogenic magic bugs and hallucinogenic insects is, the ability to make people hallucinate still exists, right? That's enough!

Brian couldn't understand what Jia Zhengjin was doing from beginning to end, but he honestly stayed on the side and didn't say a word, just holding his magic wand and maintaining the effect of illumination.

Illumination doesn't take much mana and lasts a long time, so there's no need to worry about running out of power.

When Jia Zhengjin seemed to be finally busy, Brian asked softly, "Can we go?"

"Wait!" Jia Zhengjin thought for a moment and took out a torch from his virtual backpack.

Sure enough, after the One-Horned Demon was killed, the Fire-Weary Barrier was gone!

Jia Zhengjin put the corpses of the one-horned demon and the little demon together, and lit a fire to burn them clean. For the undead, what he fears most is to cut the grass without eradicating the roots, and it may be resurrected at any time! The previous greedy zombie Alex taught him a great lesson, so he must not make the same mistake again!

It was only when the bodies were burned to ashes that the two returned to the steps. Looking at the corroded steps, the only way to return, Brian turned his head to look at Jia Zhengjin: "What should I do?"

"Don't worry!" Jia Zhengjin unhurriedly took out an iron pickaxe from his backpack and made some steps out of stone bricks, "Just replace them with new ones!"
