After saying goodbye to Hagen, Jimmy and other underground humans, Jia Zhengjin, who returned to the underground palace, looked down at the "tiger" who was locked in a small cage similar to a birdcage, constantly turning around and roaring fiercely, and felt that it was still a small animal with a temper, and it seemed that he had to repair a special book to remind Tina to pay attention to safety when raising them.

Even if it's only the size of a mouse, it's possible to bite off a person's finger if it's ruthless.

When he arrived at the teleportation magic array, he found that the demon king Singh was covered in injuries and was sitting next to him panting, looking very weak.

No one else was seen except him.

"Looks like the battle is over!" "As I expected, the Demon King summoned by sacrificing the body of the previous master won." ”

"It's really ......," Jia Zhengjin stepped forward, stood in front of Singh, and asked worriedly, "Hey, are you okay?"

"A little injury, a few days of recuperation will recover!" Singh replied indifferently, with a proud face.

"What about the other four demon kings?" Jia Zhengjin asked, after all, their bones were all useful.

"Dead!" Singh replied coldly, "The defeated are not qualified to live, this is what will happen if you fight with me for the throne of the Demon King!"

"Uh~~ What about their corpses?" Jia Zhengjin hurriedly said, "I'm useful." ”

Hearing him say this, Singh casually pointed to create a black hole in front of Jia Zhengjin. Then the four stiff corpses of the defeated demon king fell from the black hole one after another and fell at his feet.

Seeing that the corpses of the demon king were still there, Jia Zhengjin breathed a sigh of relief. What he was most afraid of was that after the fight, Singh would throw the corpses of these demon kings somewhere and not bring them back.

"Are you really okay?" asked worriedly, looking up at Singh again.

"I said it, you can recover in a few days!" Singh replied indifferently.

It seems that the demon king still has a temper, although he obeys orders, but his tone is not very good. Jia Zhengjin was sure that he was fine, and immediately said: "Then you go to the dormitory first and find a room to live in and recuperate." I'll be back on the surface soon, and I'll call you when I need it. ”

"Whatever you want!" Singh staggered to his feet, holding his bruised body and slowly walking away, disappearing in front of Jia Zhengjin's eyes.

"It's a pity~ If he can reach the strength of the previous master himself, there is no threat to any enemy in front of him. Shemos said, looking at Singh's back.

Jia Zhengjin didn't reply, just looked down at the corpses of the four defeated demon kings, thinking about what to do.

To be honest, he would love to build the Demon Castle, as it would be built without only 2,000 Bloody Stones. With the materials currently in hand, at least 1 Demon Castle can be crafted.

The question is, where did this bloody stone come from?

If you can get it, after creating a demon castle, maybe you can use the corpses of these four demon kings to sacrifice and summon super demons that are even more powerful than the demon kings?

If that were the case, it would be easier to deal with the Dark Dragon.

The question is, what exactly is the Bloody Stone, and where does it come from?

"Shemoth!" He suddenly remembered, wasn't there a magical creature made by a super demon beside him? Maybe he knew? Thinking of this, he immediately turned his head to look over his shoulder and asked, "Do you know the bloody stone?"

"Bloody stones, of course you know!" Semos nodded, "The previous master once said that it was a special building material in the Demon Realm. It seems that the blood of countless demon corpses has penetrated into the ground for about a thousand meters, and it will only be formed after being impregnated with a special stone for hundreds of years, which has the special effect of condensing magic power, and is the demon's favorite building material. ”

"According to you, you can only find this kind of stone by going to the Demon Realm?" Jia Zhengjinton was disappointed.

"Of course," said Semos, shrugging his shoulders, "because this is a mineral unique to the Demon Realm! However, it's useless to ask for this kind of thing! Only demons need bloody stones, and they are ineffective against humans. ”

"The Gate of the Demon Realm......" Jia Zhengjin sighed slightly, but immediately thought of something, "That's right! If you go to the Gate of the Demon Realm, this time you will go to the Coastal Country, and the Dark Dragon will open it! Maybe when the time comes, I can enter the Demon Realm through the Gate of the Demon Realm?"

Then I thought about it, no!

Because the dark dragon wants to open the gate of the demon world, he wants to awaken the demon god and release the super terrifying guy.

The purpose of this trip is naturally to prevent him from awakening the demon god, and even the gate of the demon world cannot be opened.

If for the sake of selfishness, you let the dark dragon awaken the demon god, this world is probably going to end, and you have to end with it!

So, don't mess around. Go to the demon world, and think of other ways later. Or you can give up this option, after all, having a demon king is already quite powerful, so why force a super demon?

In that case, these demon king's corpses should be used elsewhere!

At present, the first place that can be used is the creation of the Demon Staff, which requires a Demon King Hand Bone, a bottle of Demon King's blood, and a Demon Crystal.

These materials can be made now, but it is very difficult to make them.

Although it is an epic weapon, it will slowly erode the user's sanity until it turns a person into a demon......

What if the user is a demon in the first place, or a dark creature who is not afraid to turn into a demon?

By the way, maybe you can make a demon cane and see it, but as long as you don't use it yourself, you'll have no problem at all. Just look at the properties and decide who to use them.

Then you can also use several other parts of the demon king's body to create a high-level teleportation magic array, and your own Holy Dragon City will definitely have one, and other places depend on the situation.

Therefore, first of all, all the corpses of these demon kings should be collected, and the parts of their corpses should be kept at any time.

Jia Zhengjin immediately made a move, took out a dagger and began to collect the corpse of the demon king, and stopped when the last demon king came.

After thinking about it for a while, I decided to keep a complete corpse, maybe in the future, the Demon Castle will be successfully built, and I can use him to summon super demons? Even if it is unlikely, it is an unimaginable combat power!

Anyway, the parts of the corpses of the three demon kings are enough for the time being, so there is no need to waste them!

So he decisively put the complete body of the last demon king into the virtual backpack.

Shemos watched him collect the corpse of the demon king the whole time, and he felt quite surprised. After all, the Demon King is a rather terrifying existence for ordinary people. As a result, not only could he command the Demon Kings, but he could even dispose of their corpses without pressure or respect, which was unimaginable. The new underground palace manager also seems to be a rather mysterious character.
