Probably because they fought too seriously, neither the necromancer nor the guards found Jia Zhengjin passing by them.

Just like that, he traveled through the past without hindrance, and took a closer look as he passed by the necromancer. It turned out that this guy had no place to hide the demon core at all, wasn't it on his body?

Go inside and come to the interior of the room. Behind the desk there was a wooden box, where it lay quietly.

Glancing back at the undead and guards in the fierce battle, Jia Zhengjin opened the box as carefully as possible without making too much noise.

【System】You have opened Obi's treasure chest!

【System】You have obtained the blueprint for building a bicycle!

【System】You have obtained the Skull Staff (Normal)!

【System】You have obtained the Book of Intelligence!

【System】You have obtained the Book of Beginner Experience!

【System】You have obtained ale!

【System】You get a chunk of bread!

There were three drawings, and the luck was not bad!But there is no dark magic core, has it been used?

【Bicycle Manufacturing Drawings】After learning, you can make a lightweight and convenient bicycle. Materials required for manufacturing: 2 bicycle tires, 1 bicycle rack, 1 handlebar, 1 bicycle cushion, 1 cargo basket. Prerequisite: Carrier Technology Lv1.

After learning, it is immediately prompted that the formulas of each component of the bicycle are also mastered instantly, and the carrying technology is only level 1, which has been ordered. This means that this simple vehicle is already capable of making itself!

Although it is said that with a pen of beasts, it is completely possible to capture beasts and domesticate them into mounts, and the speed is definitely faster than that of a bicycle, and it does not require the user to exert effort. But in the past life, such as bicycles, can give people some familiarity. Moreover, it is not good for wild animals to run around in the city, and it is relatively better for people to use bicycles!

【Skull Bed Fabrication Drawings】A large bed made of bones gives a terrifying feeling. A favorite resting place for undead creatures, it can effectively increase the mana recovery of undead creatures. Materials required for crafting: 4 skulls, 200 bones, 50 wood!

What the hell is this? Jia Zhengjin showed a disgusted expression, using skeletons to make a bed, normal people don't dare to sleep well? It's like the kind of necromancer who is fighting behind him, and all kinds of necromancers like it, right?

Is this kind of drawing useful? Just throw it away!

But when I think about it, it's a trophy anyway, and it's a pity to lose it. It's not bad to learn to unlock new crafting skills, at least the crafting list looks complete, which makes people feel comfortable. Anyway, this kind of thing, just learn not to do it!

Thinking of this, decisively learn it.

【Skull Staff Crafting Blueprint】A staff made of skeletons has a special bonus to undead magic!Materials required for crafting: 1 skull, 10 bones, and 1 fresh blood.

It's a necromancer's weapon manufacturing blueprints!But that's what they're asking for, so it's no wonder that necromancers are hated by the world!

Venom Bomb: A bomb full of poison that will cause a powerful explosion when thrown, vaporizing the poison and spreading it. Targets within a radius of 100 meters will inhale the toxin and fall into a state of poisoning!

Bombs? And venom...... This thing is definitely ineffective for Jia Zhengjin himself, but he doesn't know if this poison is powerful or not, and how lethal it is to the enemy.

[Skeleton Staff] (Normal) Magic Attack 50, Undead Magic Increase 15%, Intelligence +15! Equipment Requirements: Magician.

What a rubbish magic wand, the magic attack power is only 50 points, and it is limited to the mage class...... However, speaking of which, the necromancer's magic increases by 15%, and it also adds 15 points of intelligence, which is still a good weapon for beginner magicians, especially necromancers.

Of course, the Book of Intelligence is to keep it and bring it back to Christina or Tina, and I don't need the attribute of Intelligence myself anyway.

The Book of Beginner Experience is, of course, used on the spot and earns 100,000 XP.

Of course, these 100,000 XP points are pitifully small compared to the more than 13.1 million upgrades required for the next hit!

At present, Jia Zhengjin has barely reached level 18, and the experience requirement has become so terrifying. If you want to reach level 30, it is probably not easy!

The ale smells quite good, but the alcohol concentration doesn't seem to be high. Of course, it doesn't mean much to Jia Zhengjin, and he doesn't like to drink anyway.

As for the large loaf of bread, it doesn't seem to be very attractive because it is too simple.

After scavenging the contents of the chest, he turned his head to see that the necromancer had been defeated by Priest Spike and the captain of the guards, and had to rely on zombies to support him!

Where the hell is the core? Is it really used?

Hmm~ Why don't you go into the cave inside?

Jia Zhengjin hesitated slightly, and immediately drilled deeper into the cave from behind.

Walking down the passage for a while, it turns out that it is a separate room inside. There were several human corpses lying in the room, all of which had been turned dry. There was a bed next to the corpse, and there was a small wooden treasure chest next to the bed.

On the other side of the room, there was a small oval-shaped bath, and the vampire just now was lying in it with a look of enjoyment. It's just that the bath is not water, but bright red blood!

Jia Zhengjin frowned, and accidentally kicked the dry corpse next to him.

"Who?!" the vampire immediately jumped out of the pool of blood vigilantly and quickly looked around.

Jia Zhengjin turned his head in disgust, this vampire was naked. If it was a beautiful woman, he wouldn't mind admiring it, but there was a man on the other side.

The vampire didn't seem to be able to find the invisible Jia Zhengjin, and after carefully checking the room for a week, he looked down at the wormhole on the ground: "Is it a bug?"

Why don't you put on your clothes first?" Jia Zhengjin stood motionless and thought to himself.

"Hey~" The vampire didn't know if he heard Jia Zhengjin's heart, so he slowly walked to the side of the bed and reached out to grab his clothes, and began to put them on slowly, while sighing and saying, "It's really humiliating! The dignified Baron Euphos, but he has been reduced to regaining his strength with the help of Obi's power, which is really humiliating! However, in order to be able to recover his strength, in order to be able to return to the Temple of Blood and regain my position as a baron, no matter how great the humiliation is, I will have to bear it! There are still 30 living people's blood left, and my injuries can be recovered." Temple of Blood...... I'll be back soon!"

The Blood Temple is a vampire organization, right? In the Holy Dragon City before, Jia Zhengjin encountered it.

"Obi, isn't that guy okay? The guards in a small city, plus an unruly priest, have to fight for so long? This guy, it's so weak......" After getting dressed, the vampire snorted softly and walked outside.

Jia Zhengjin's eyes lit up, and after making sure that he left, he immediately ran to the side of the bed and opened the treasure chest directly.
