Jia Zhengjin used a steel axe to quickly cut down, quickly cleared a large area of open space, and then surrounded it with a layer of stone bricks just in case.

Then all the wood that was cut down was piled on the body of the zombie king, and he was completely buried. Then a fire raged, and he and Perrin kept adding firewood to the fire.

After burning for a long time, the Zombie King finally turned into ashes completely! This also means that it will never have a chance to resurrect, and it will not be possible to come back to trouble Jia Zhengjin!

Alex and Jia Zhengjin's grievances and hatred have finally come to an end at this moment!

"Let's go back!" making sure it was burned clean, Jia Zhengjin reached out and grabbed Perrin's hand, blew his whistle to summon the imposter dragon resting somewhere nearby.

"Wait!" Perling pulled him towards the ash heap, fiddling with her saber.

"What's wrong?" asked Jia Zhengjin suspiciously.

Perrin continued to fiddle with a blank face, and quickly picked out a prismatic black crystal from it: "What is this? I see that it is very different from the color next to it!"

"Huh, your eyes are so good, I didn't even pay attention!" Jia Zhengjin paused for a moment, and hurriedly bent over and reached out to pick it up.

【NEWS】You have obtained the Broken Core of Darkness (Lv8)!

[Incomplete Dark Core] (Lv8): A dark attribute core that has not yet been fully formed. Unfortunately, it doesn't have much use!

Seeing the introduction, Jia Zhengjin's face darkened. The system even has such funny words. But I really didn't expect that the zombie king that Alex had become had not yet been upgraded to the Nightmare Messenger and turned out to be an eighth-order demon core! In other words, he was classified as an eighth-order demonic beast?

But it's also his own luck, if Alex is smart enough to fully upgrade to the eighth order and then come to trouble him, I'm afraid it won't be so easy to deal with! It also happens to be the appearance of the night of the blood moon, and his consciousness has not fully recovered, so he can only rely on instinct to act, so he has avoided a catastrophe! If he evolves to the eighth order, or even to the more powerful ninth order or even a terrifying nightmare messenger than the ninth order, then it will be a destructive existence!

Thank you Alex, you are really a good person!" Jia Zhengjin said secretly in his heart.

Trying to throw away this broken dark core is useless anyway. Suddenly remembered that I don't know if it can be used to unseal the mysterious sword! Although it is incomplete, it is also an eighth-order demon core!

Thinking of this, he immediately took out the mysterious sword from the virtual backpack, and at the same time placed the broken dark core on the sword body.

【News】If you find that the conditions of the mysterious sword are met, will you immediately lift the seal?

Jia Zhengjin showed excitement and immediately chose to be sure.

"Keane, what is this?" Perrin looked at the mysterious sword that suddenly appeared in his hand, puzzled.

"I'll tell you later!" Jia Zhengjin concentrated and stared intently at the Dark Core and Mysterious Sword in his hand.

A gentle light appeared, and the core of darkness began to merge into the mysterious sword at an astonishing speed, quickly carving the entire mysterious sword that did not look very good, and quickly carved the shocking sword body pattern.

"Wow!" Jia Zhengjin was dumbfounded, these lines were simply magical!

"What a beautiful ......" Perrin, although her face was expressionless, she also looked intently.

When the core of darkness was completely integrated into the mysterious sword, and the lines on the sword body became clearer, Jia Zhengjin felt a powerful force emanating from it.

【NEWS】You have successfully lifted the seal of the Mystic Sword (Legendary)!

【News】You have been blessed with Anema!

"Annema's gift, what the hell?" Jia Zhengjin felt inexplicable, the real name of this sword was so ugly.

Perrin, who was standing next to him, said expressionlessly, "Anema is the goddess of life!"

"The goddess of life?" Jia Zhengjin was stunned, "Then why not call it the gift of the goddess of life?"

He picked up the unsealed sword and took a closer look.

【Gift of Anema】(Legendary)Attack 1, don't use it to pierce the heart of your enemies!The Gift of the Goddess of Life, for your family and friends!After 10 uses, Anema will take it back. The current number of uses (0/10), you still have 10 more trials.

"I'll go!" Jia Zhengjin was speechless, "What kind of broken weapon is this?After the seal is lifted, the attack power is still only 1 point, and the profile actually told me not to use it to pierce the enemy's heart?He actually let me use this sword on my family and friends, and I only have ten chances to try it...... It's rubbish!"

"......" Perrin was silent on the side.

"What's the use of this thing?" Jia Zhengjin really couldn't laugh or cry, and turned his head to ask Peilin.

"Since it is a gift from the goddess, it must have a magical effect!" Perin replied expressionlessly, "The elven clan worships the goddess of life, Anema, why don't you go back and ask!"

"That's right!" Jia Zhengjin's eyes lit up when he heard this, and he hurriedly hugged Pei Lin's head and kissed it, "You're still smarter!

"Hmm!"

Summoning the counterfeit dragon, Jia Zhengjin and Pei Lin jumped on the dragon head together, and let it carry the two of them back the same way and fly in the direction of the Holy Dragon City.

On the way back to the city, Jia Zhengjin first put Annema's gift in his bag, thinking about what to use the skill points he got after reaching level 16 this time!

Now there are two directions to choose, one is the production workshop, the premise of manufacturing is lathe and machine tool, now he has been put together, it can be manufactured!

The production workshop is actually equal to the combination of lathe and machine tool, with which it can manufacture lathe molds and machine tool machinery, and can make more sending accessories!

The other direction is to point out the power system and machine shop first, and then the science lab!

After learning the power system, he can manufacture some basic electronic parts, and in the future, he can also manufacture more electrical appliances when the level of power knowledge is improved, so that he can enter modern life.

The machine shop is, of course, the evolution of machine tools, and it is also necessary for the production of various large machines and robots in the future. Of course, the required mechanical knowledge must also be very high to be able to use. To truly modernize, this is essential!

And the power system and machine shop, together with the science laboratory lit by the machine tools, is the most important beginning of all science!

With the Science Lab, you can use skill points to upgrade countless fields including mechanical knowledge, electricity knowledge, vehicle technology, architecture, weapon knowledge, defense knowledge, drug knowledge, etc., and truly embark on the road of science!

After weighing the importance, Jia Zhengjin finally chose to use his skill points on the power system!

It is still the most important science laboratory, and it is also what he needs the most! With the upgrading of science, many powerful technologies can appear! Moreover, the basic power system can also make some electronic parts that can be used in ordinary times!
