Guoyun: My system comes with Marvel's black technology

Soon after, a short battle took place in the dense forest.

Zhan Er, who was at level 20, personally took action with terrifying force and directly suppressed the thirty or so elites from the Goblin Kingdom.

Even the eighteenth-level Goblin Lord who was leading the group had no power to resist Zhan Er.

"My lord, have mercy on all races!"

"All races should respect and believe in the Lord!"

With Zhan Er's whisper, the goblin warriors from the Goblin Kingdom were terrified. They looked at the powerful iron warrior floating in the air, expressionless, holding a huge axe and looking at them.

The goblin warriors struggled for several minutes, their courage was gone with the wind, and they finally knelt on the ground and begged Zhan Er for mercy.

"Take him back to the castle and let the lord decide.!"

"As you command!"

Black Tech Castle.

Time passed, and the auction of the Skeleton Warriors' architectural drawings had come to an end. The current bid price was as high as 7,040 soul stones, which shocked countless castle owners.

The world chat channel also became unusually lively because of this auction.

"A blueprint auction actually made my blood boil!"

"Where did this castle owner come from? He is so rich! He offered more than 7,000 soul stones! Even if I searched my castle from top to bottom, I couldn't find so many soul stones."

"I heard that it only takes 5,000 soul stones to upgrade a military structure to level 4!"

"Have all the troop buildings of the castle owners participating in the auction been upgraded to level 4??"

"I'm only level 2!"

"I just got promoted to level three.!"

"That's the difference!"

"At this stage, no one can come up with so many soul stones at once! I heard that in order to bid for this military construction blueprint of Tang Xiaofan, many top castle owners are borrowing soul stones everywhere."

"I heard it too!"

"This news is indeed true! A friend of mine borrowed 300 soul stones from me and signed a notarized agreement to return 500 soul stones to me within a week.!"

"So, they are not rich, but they are in debt.!"

"This is playing with your life.!"

"does it worth?"

"Of course! As long as you can grab this troop building blueprint from Boss Tang Xiaofan, it will definitely be worth it! What’s the soul stone? With two troop buildings and double the number of troop summons, are you still afraid of not having soul stones?"

"I can only say that at least they can borrow soul stones. I also covet the blueprints, but I can't get soul stones at all."

"This is a feast for the top castle lords! High-level castle lords are not qualified to participate!"

"With just this wave, Tang Xiaofan will become rich overnight.!"

"Maybe Tang Xiaofan can upgrade the military structure to level 4.!"

"It seems that up to now, no one has upgraded the military structure to level 4? Even the top castle owner should still be one level short."

"I just have to say one thing: I envy Boss Tang Xiaofan!"

"Tong Xi +1."

Tang Xiaofan glanced at the lively world chat channel.

Seeing the information that appeared in the channel, he didn't have too many thoughts.

It was certain that he would become rich overnight. As for relying on the soul stones from the auction to upgrade the military structure to level 4, this was purely underestimating him.

When the beast tide ended yesterday, his farmer factory had already been upgraded to level 4.

At present, he is continuing to reserve soul stones and moving towards level 5 military buildings. It seems that it won't take long before he can start upgrading again.

This is the speed of his castle development.

No castle lord can match him.

Finally, the auction ended, and the skeleton warriors' military building blueprint was auctioned off at a sky-high price of 7,200 soul stones.

As for who won the blueprint, no one knew.

Including Tang Xiaofan, of course, he didn't care.

Whoever bid for it would be fine. Even if he took away this army building blueprint, it would not shake the deterrent power of his warrior team on the castle forces. The castle lord who took the army building blueprint would at most speed up the development.

As for the castle battle, even if there is an additional mid-level army, it is not a threat at all.

Just like Tang Xiaofan, in addition to farmers and goblins, his army also has angels, which can be listed as top-level advanced arms.

Would he care about the addition of a mid-level army in the hands of other castle lords?

Obviously he would not care.

This level of army, no matter how many there are, is just a stronger cannon fodder on the battlefield.

Their role is to speed up the development of the castle forces in the early stage. They are of no use in the middle and late stages of the war.

In the burial ground, in a dark bone castle, a figure in black armor breathed a sigh of relief.

"Finally got the shot!"

"Those people really worked hard for this blueprint.!"

"But in the end, it finally fell into my hands!"

The figure looked at the azure blue drawing that appeared out of thin air in her hand, and her eyes narrowed slightly under the black helmet.

Then, she came to the courtyard of the Bone Castle.

【Whether to build a Skeleton Warrior building in the currently specified area?】

【whether】

""Yes!" As soon as she finished speaking, the blue blueprint disappeared from her hand.

With a slight earthquake, a large golden light suddenly appeared in front of her, and there was a shadow of a building in the golden light.

Soon, the shadow became real and quickly transformed into a military building that could recruit skeleton warriors. In just this moment, she consumed 100,000 units of wood, 50,000 units of stone, 10,000 units of refined iron, and 5,000 units of soul fire.

In the burial ground, stone and soul fire can be found everywhere, and they are not scarce resources.

But wood and refined iron are difficult to obtain. It took her a long time to prepare these materials. They were originally used to upgrade the primary town.

Now it seems that her castle cannot be upgraded in a short time.

As for her death knight military building, it is also difficult to upgrade to level 4 in the near future.

In order to bid for the skeleton warriors' military building blueprints, her reserve of soul stones has bottomed out, and she also deducted an additional holy-level light ring at a low price.

"But anyway"

"If you can take a picture of the blueprint, you will make money!"

She felt much better as she looked at the building that appeared in the castle courtyard.

【Boneyard: Intermediate Arms Building】

【Initial level: Level 1】

【Seven Skeleton Warriors can be recruited every day】

【Special reminder: When recruiting Skeleton Warriors in the Skeleton Cemetery, there is a certain chance that Skeleton Mages, Skeleton Knights and other types of soldiers will be recruited】

【The Skeleton Cemetery is full of energy. Do you want to recruit Skeleton Warriors??】

【whether】

""Yes!"

A command was given, accompanied by a sound like ghosts crying.

The skeleton cemetery was filled with gray fog.

Soon after, the gate of the cemetery opened, and a team of undead soldiers walked out.

Six skeleton warriors and a skeleton mage.

The initial level was level two.

At this time, she walked over, kicked a skeleton warrior to pieces, and then threw a bone staff to the skeleton mage.

The skeleton mage held the bone staff, sniffed and called twice, and when the bone staff was swung, the skeleton warrior who was kicked to pieces was resurrected again, but the soul fire was a little dim.
