Tang Xiaofan took the black sword.

He waved it casually, and black air emanated.

However, before the black air could dissipate, it was purified by the holy light from the eighteen-winged angel statue in the temple, and a faint shrill wail could be heard.

"good!"

“It can be sold at a good price!”

Tang Xiaofan has no habit of using it himself, and he doesn't want to collect it and waste its value.

It should appear in the trading channel, making countless castle lords of the undead camp crazy about it, and obediently hand over soul stones to help his black technology castle develop rapidly.

at the same time,

Tang Xiaofan thought again of the dark elf that appeared in the underground little loli castle.

If the dark elf wanted this holy artifact, or could help him find a generous customer, it would be best to sell it to the local forces, as they would definitely make more money.

Tang Xiaofan hurriedly checked the information of the black sword. If its attributes were good, the price would definitely be higher.

[Skeleton King Lion's Holy Sword]

[Level: Holy Artifact]

[Effect: Greatly improve the loyalty of the undead troops]

[Can release a second level 21 single-target combat skill: Holy Undead Slash]

[Increase the attack of undead soldiers by 15%]

[Effect: There is a higher probability of attracting active surrender from undead creatures]

[Special reminder: This is the sacred weapon of Skeleton King Ryan. Using it will increase the hatred value of creatures in the good camp!]

"This attribute is good!"

Tang Xiaofan took a breath, feeling extremely surprised and amazed. The Skeleton King, a 21st level undead creature, had actually created such a powerful holy weapon.

Tang Xiaofan thinks.

Its most powerful attribute is its effect.

Increases the attack of Undead troops by 15%.

This is a very abnormal attribute. Once the castle lord of the undead camp obtains it, the strength of the undead troops under his command will increase dramatically.

Especially in the middle and late stages,

After the size of the arms corps expanded.

The strategic value of this Deathly Hallows will be even more astonishing.

In addition, the Holy Sword of Skeleton King Ryan also comes with a twenty-level single-target attack magic, Holy Undead Slash, and has a high probability of attracting active surrender from undead creatures.

The value doubles! "I'm a little envious of this attribute!"

Tang Xiaofan felt a little jealous. He also had a holy weapon, the Ring of Glory.

Although it is not bad, it also comes with a level 21 attack and defense.

Just based on this...

The value of the Holy Light Ring is not as great as that of the Holy Sword of Skeleton King Lion.

At least that's the case for the castle lord. After all, the foundation of the castle lord is the army.

A weapon that can increase the attack power of a soldier by 15%, this is a godly weapon! "This is the Deathly Hallows,"

"It belongs to the Skeleton King Ryan's natal sacred weapon."

"It may have taken hundreds of years of nourishment from its soul essence for it to be promoted to the holy weapon level!"

"Naturally, its properties are excellent!"

Tang Xiaofan was a little reluctant to put it on the trading channel.

He was not worried that it would be bought by the castle lord, thus creating a powerful enemy for himself in the future.

To be honest, Tang Xiaofan didn't really take this issue seriously. What he was worried about was that the castle owners couldn't afford the high price.

Thanks to this top-grade holy artifact of the Undead.

"It seems that we still have to find that dark elf! If she has a buyer, that would be great. Relatively speaking, the local forces are far more powerful and richer than the current castle lord."

While thinking, Tang Xiaofan put away the Holy Relic of the Undead.

Then he looked at the rest of the spoils,

9,753 soul stones.

Drawings: 8 A real bumper harvest.

Tang Xiaofan grinned, feeling very good, but he also knew that such a huge harvest was entirely due to the fact that the two conquered forces were both strong.

That top-level military castle has nearly eighty headless knights and is very powerful, ranking in the upper middle level among all the top-level castle forces.

The Tomb of Bones is even more powerful, with an army of tens of thousands of undead, plus a level 21 Skeleton King.

At this stage,

I'm afraid that except for Tang Xiaofan's black technology castle, no other castle force can capture the Tomb of Skeletons.

Anyone who dares to be greedy will surely die.

The enemy is powerful.

Correspondingly, the supplies will not be too scarce.

Tang Xiaofan stored the soul stone in the Cyclops' ring.

Then he looked at the blue drawings.

There were eight in total, and he identified them.

Finally, I got the residential blueprint and the arrow tower blueprint. The most surprising thing was the skill blueprint of the Skeleton Undead Transformation.

Tang Xiaofan decisively used the residential buildings on the blueprint. In the blink of an eye, thirty more residential buildings appeared in the castle, bringing the total number to one hundred and ninety.

Then came the arrow tower blueprints and the wall blueprints, which he put on the trading channel at the value of eighty soul stones and three hundred soul stones respectively.

The second is the Skeleton Undead Transformation on the skill blueprint. [Skill Blueprint: Skeleton Undead Transformation]

[Master the magic skeleton undead transformation technique of the undead Chen Ying. ]

[The casting method consumes soul stones to transform the dead bodies of creatures into undead creatures of the skeleton clan. ]

[The higher the level of the corpse when it was alive, the more soul stones it consumes. 】

[Magic can only transform skeletons and undead spirits, not other types of undead creatures.]

"good!"

"This skill blueprint is also very valuable!"

"Although it's not as good as the original Skeleton Warriors' architectural blueprint, it can definitely be sold for a good price! It's enough to attract the attention of countless castle lords from the Undead Camp!"

"To the castle lords of the Undead camp."

"The Skeleton Undead Transformation Technique is very useful!"

Tang Xiaofan was filled with emotion, but also a little helpless...

The two blueprints he revealed, the soldier-type building and the skeleton-undead transformation technique, are both from the undead camp, and are natural enemies of his black-tech castle.

Even though he was jealous, there was nothing he could do but to auction it off.

"After all, it's good to be able to exchange it for a lot of soul stones!"

While thinking, Tang Xiaofan put the Skeleton Undead Transformation Skill Drawing on the trading channel.

The starting price is one thousand soul stones.

The bidding time limit is twelve hours.

Auctioneer, Tang Xiaofan.

Drawings are up for sale.

The world chat channel next to them suddenly became lively. "I got the skill blueprint. Master Tang Xiaofan is awesome!"

"This is the first time I've seen a blueprint for a magic skill, and it's a magical skill for the Undead camp. It can directly transform a corpse into a Skeleton Undead!"

"This is simply a magical skill. The castle lord of the Undead Army must be going crazy!"

"Why? Is there anything special about this skill? It looks very ordinary to me!"
