The construction of the post office has been put on Luo Ji's agenda.

Before this, it is undoubtedly necessary to train a large number of homing pigeons.

At the same time, publicity must be adequate.

At least all the people in the civilization of all worlds must know.

Nowadays, there are services such as letter delivery and express delivery.

And because those who master the training methods of homing pigeons are basically elves.

Therefore, this matter was left to Zhang William to arrange.

At the same time, Luo Ji also learned more about some other special professions among the elves.

For example, naturalist.

To put it simply, the main job of elven naturalists is to study the ecological environment, protect plants, green construction, etc.

The moment I learned about the existence of this group of naturalists.

Luo Ji quickly found them a suitable job.

There is a large amount of desert terrain in Huangsha City that needs them to save.

At the same time, although the artificial lakes he dug before are all connected to rivers, the ecological chain at the bottom of the lakes still needs to be improved.

It would be best to form a complete ecosystem in the lake so that the water quality can become better.

And this job was obviously given to them as well.

At the same time, the planting industry of the elves is very developed.

Especially under the influence of the ancient elven tree.

The development speed of the planting industry is even more rapid.

Luo Ji gave the order directly.

Build glass greenhouses in each elven city.

At the same time, the cultivation of some precious medicinal materials and plants was also handed over to the elves.

In the future, the elven provinces are expected to become important 'planting industry' output provinces within the civilizations of all realms.

Of course, in addition to this, there is also the special profession of elf craftsman in the elf province.

The special thing about elf craftsmen is that they can forge magic weapons.

Up to Zhang William, the elf king’s sword Breath of Storm.

Down to the consumables used by the Elven Archer Troops, the Wind Chaser Arrow.

All are made by elven craftsmen.

Based on this alone, their importance is beyond doubt.

Quickly confirm and arrange things one by one.

During this period, Luo Ji returned the Breath of Storm to Zhang William quite simply.

At the same time, he was also officially canonized as the city lord of Senhai City.

Senhai City can be considered a big city among the entire Elf Province.

No matter how you think about it, it's not like you treated him badly.

William Zhang himself was also very surprised by this.

Senhai City aside, what he didn't expect was that the Breath of the Storm could come back to his hands.

Luo Ji should be very clearly aware of the rarity of level three magic cores.

And now such an extremely rare magic weapon is back in his hands?

At that moment, William Zhang himself was a little unbelievable.

Even the loyalty level has clearly risen to seventy-five points.

But in fact, this matter was nothing to Luo Ji.

Short-handled weapons, what he is best at now is using knives.

In comparison, he is better at using spears.

Holding a sword, no matter how good the sword is, if he doesn't use it smoothly, what's the point?

Of course, Luo Ji wanted the elf craftsmen to tailor-make his own magic weapons and armor.

However, because of the existence of 'steel-making', he was a little hesitant in his heart.

He has already confirmed all the materials needed to refine steel.

We just have to wait for the mining field to be established, and after a wave of mining, we can start refining steel.

When the time comes, wouldn’t it be better to just forge weapons and armor out of steel?

With this in mind, he had to confirm a question.

"Karl, let me ask you, suppose a magic core has been embedded in the weapon, but then you find better forging materials. In this case, can the magic core be completely removed again?

?”

Faced with such a question, as the top elf craftsman among the elves, Karl rubbed his chin.

Because things like this rarely happen.

Generally speaking, weapons that need to be inlaid with magic cores must have used the most advanced forging materials at that time.

It is unrealistic to find a better one in a short period of time.

However, he is a top elf craftsman after all. After a little thought, he figured it out.

"Your Majesty, the magic core is extremely hard and cannot be damaged under normal circumstances, so it can be removed."

Luo Ji was obviously relieved when he heard this.

Then I calculated the time and found out how far away the ore mining was from the bitter cold land.

Then refine the steel.

I think it will take two or three years to say at least.

During this period of time, it was impossible for him to still be wearing bronze armor.

"Okay then, I order you to tailor-make a set of equipment for me as quickly as possible."

"As a humble official, I would like to ask Your Majesty, what kind of magic core should be inlaid on the armor and weapons?"

After taking over the task, Karl decisively entered a working state.

Faced with this question, Luo Ji couldn't answer it for a while.

Then he turned to look at William Zhang who was standing aside.

"William, how many magic cores are there in the inventory now?"

"Reporting to Your Majesty, there are no more third-level magic cores, but there are still fourteen second-level magic cores. I will ask someone to get them right now."

After all, magic cores are rare resources. Even the lowest level first-level magic cores are all stored in the palace treasury.

During this period, Luo Ji also checked the inventory of magic cores.

The answer is fourteen second-level magic cores and sixty-one first-level magic cores.

This is the accumulation of Zhang William's elf civilization that has developed for hundreds of years.

This made Luo Ji further realize how rare and precious the magic core was.

The fourteen second-order magic cores were quickly delivered to Luo Ji's eyes.

It is obviously smaller than the third-order magic core.

I guess it's only about the size of a pigeon egg.

At the same time, there are many colorful colors.

There was no need to say more, Zhang William, standing aside, explained directly.

"Your Majesty, these five azure magic cores are wind magic cores, these three yellow magic cores are earth magic cores, these three blue magic cores are water magic cores, and these two red

The magic core is a fire magic core, and this purple magic core is a thunder magic core."

Hearing this, Luo Ji subconsciously reached out and picked up the second-level thunder magic core, then raised it to his eyes and looked at it.

In the purple magic core, you can still vaguely see electric current flashing.

It looks really extraordinary.

"Speaking of which, I am also a lightning type, right?"

"Yes."

"Then if my weapons and armor are embedded with magic cores of other attributes, will they be effective?"

Luo Ji asked worriedly.

"Your Majesty, please rest assured that as long as the attributes are not conflicting, the effect will be triggered. Of course, if the attributes are compatible, the effect will be better."
