"Lord, what are you?"

Watching Lu Yuan move a large amount of materials out of the trading market, he was a little surprised.

"It's nothing, just got a few more recipes, and an architectural drawing, to procure some materials."

Hearing Lu Yuan's words, he was also a little stunned.

Other lords want to get some recipe blueprints, and it's very difficult.

But here is his father-in-law, it is a relaxed freehand, and the formula seems to be free of money, and he takes it back in batches.

Before a building is finished, a new one comes in.

"Ahem, the lord, the barracks and other buildings have been upgraded, and the upgrade conditions of the lord's hall have been met, do you want to upgrade immediately?" Frustrated asked.

To upgrade to a level 4 territory, you need to have 10 level 3 buildings in the territory in addition to the previous materials.

Lu Yuan reminded him before he let the frustration upgrade be completed.

He checked the materials in the inventory, he had exploited the lords of the Extreme Fire Alliance in the past few days, and the gap in materials was not large, and it was enough to purchase some stones.

100,000 soul crystals was a big problem for him before, but now that he has a huge amount of money, it is naturally not a problem.

Lu Yuan passed by the barracks and checked its information.

【Barracks】

[Grade: LV3]

[Recruitable Classes: Pikemen (★★), Sword and Shield Soldiers (★★), Light Cavalry (★★★)] 】

[Upgrade requirements: Wood: 5000, Stone: 10000, Iron Ore: 5000, Soul Crystal: 10000.] 】

[Attributes: Recruit class time reduced by 10%, materials reduced by 10%]

[Description: The basic building of the Terrans, which can recruit melee troops.] 】

Upgrading to the third level gives one more class, the light cavalry.

But this class is equipped with horses, which requires stables.

Moreover, the attributes of ordinary light cavalry are not as good as those of the mad wolf knights, and they are a little weak for Lu Yuan.

And the advanced troops, which can be qualified at present, seem to be relatively ordinary.

Lu Yuan extinguished his thoughts on forming light cavalry.

And the archer camp next to it was upgraded to the third level, and a longbowman was also added, and Lu Yuan had no intention of recruiting.

The Blazing Archer and Night Elf Ranger are currently the best classes for him.

Walk to the hall of the lords.

[Whether to upgrade the territory, upgrade requirements: wood: 20000, stone: 50000, iron ore: 20000, soul crystal: 100000, there are 10 level 3 buildings in the territory. The upgrade time is fifteen days. 】

This time it took longer to upgrade, and Lu Yuan also sighed.

But after all, it still has to be upgraded, Lu Yuan did not hesitate, and directly chose to upgrade, and the territory hall was surrounded by white light again

And looking at the wallet that is a little shriveled, it feels even harder.

It cost more than 300,000 to buy materials before, plus 100,000 to upgrade the territory, and now there are only more than 800,000 soul crystals left.

Lu Yuan came to the forge workshop of the Black Iron Castle again.

"My lord, according to your request, I have been making elven ballistas for the past few days, but this thing is too difficult, and only my assistant Wycliffe can help, so I haven't made a second one yet." Dwarven blacksmith Cooper said, scratching his head.

"Well, this elven ballista is more important, and I hope you can make more people learn this drawing." Lu Yuan said.

In Lu Yuan's plan, the elven ballista will be used as an important tool for defending the city. Playing an important role in the attack against the Demon Tide, the more the better.

"Yes, I'll pick some smarter guys to cultivate." Cooper said very seriously.

"Very well, how is the blacksmith's workshop going today?" Lu Yuan asked.

"Thanks to the lord, those guys work very hard, much more skilled than when they first came, and the speed of forging is also much faster, now they can forge 15 sets of black iron suits and 300 pieces of iron armor a day. Everyone is grateful for the kindness of the lord! Cooper squeezed a stiff smile out of his face.

I have to say that the dwarf race is really not suitable for such a thing as smuggling horses.

"Okay, Cooper I see. You're going to get busy with yours first. Lu Yuan interrupted his nonsense a little helplessly.

Cooper also showed a relieved expression, and stole a glance at the orc in the corner.

Lu Yuan naturally noticed his small movements, but he didn't care either. He will not take this kind of careful thinking to heart.

He walked around the blacksmith's workshop, most of which were black iron dwarves.

These were transformed from dwarven gladiators.

Hundreds of blacksmiths crowded into the forge and worked in full swing, as if they had been working harder because of his arrival.

The sound of bellows agitation, mixed with the sound of dense gold and iron clashes, is a busy scene.

The entire workshop is clearly divided into several areas.

Blacksmiths in a large area of the area are forging black iron suits.

Their division of labor is different, some specialize in making gauntlets, and some only make cuirasses, and it is by virtue of this division of labor that new blacksmiths can master this craft as quickly as possible.

There is also an area where iron armor is being crafted.

The process of iron armor is very simple, a skilled hand, at least ten iron armor pieces can be made per hour.

Now it has become another specialty of the Absolute Cloud Collar in addition to the black iron suit.

The forging of the Serpent's Thorn and the Screaming Fire has been halted for the time being, as the Blazing Archer and Poisonblade Assassin have no plans to continue recruiting for the time being.

But what distressed Lu Yuan was that the blacksmiths on the side of the forge had now reached the upper limit of 100 people.

The only way to continue to expand is to upgrade the Forge Workshop.

And this raises new questions.

Black Iron Fort is currently considered a branch city of the Cloud Collar.

Previously, the entire secret realm was facing collapse, and the halls of the lords of the Black Iron Castle were severely damaged, and only the forge was still intact.

Now if you want to upgrade the Forge Workshop, you must upgrade the Lord's Hall of the Black Iron Keep.

However, as the main city, the level of the Absolute Cloud Leader is not as good as the Black Iron Castle, so naturally the Black Iron Castle cannot be upgraded.

Not to mention that the lord's hall of the Black Iron Castle still needs to be restored.

This goal will not be achieved in a short period of time.

But as a result, some blacksmiths were left idle.

The blacksmith shop of the Absolute Cloud Collar can arrange it, but there is no recipe for them to forge some ordinary equipment and increase some experience, which is a bit wasteful.

But at this time, Lu Yuan didn't have any good ideas.

This can only be arranged first.

But this is also him, the other lords want a special talent, and that is to beg grandpa to tell grandma, especially an important military talent such as a blacksmith.

But he was worried that he couldn't find a blacksmith!
