Ladder Advancement Table, the full name should be System Soldier Ladder Advancement Platform.

Because among its attributes, there is a huge limitation, that is, only soldiers summoned by the system can use it, and other lieutenants or non-system soldiers cannot use it!

In this regard, although Du Yun was a little disappointed, he quickly accepted it.

As long as you can increase the level of the system soldier, even if you can't unlock a new system soldier in a short time, you can continue to increase your power!

"Well, let's take a look at the upgrade conditions first!"

After his thoughts returned, Du Yun muttered to himself, and immediately activated the promotion platform.

Airplanes!

With a slight tremor in the space, a ray of light suddenly lit up in the center of the ascending platform, and then this light quickly spread out into a formation and spread all around.

When the last light dissipated, the entire ascension platform, which originally looked like it was just an ordinary stone, was shrouded in mysterious runes.

Above the platform of more than 20 square meters, a five-mang array has already appeared!

Seeing this scene, Du Yun immediately walked up without hesitation.

"Ding, it was detected that the promoter does not meet the system requirements, please replace!" When the light swept over his body, a mechanical sound suddenly sounded.

And sure enough, it was!

Du Yun knew this in his heart, and immediately looked back at the twenty soldiers who came with him, pointed to one of the Xuzhou militia soldiers, and said, "Come here!" ”

"Yes, my lord!"

The soldier answered, and he couldn't wait to walk over and go directly to the promotion platform.

After Du Yun retreated, the mechanical voice reappeared: "Ding, it was detected that the promoted person is the Xuzhou militia of the first-order army, did it cost 10,000 yuan stones to promote him to the second-order army?" ”

What the? It actually takes 10,000 yuan stones to promote a soldier?

I didn't hear it right!

Hearing this sound, Du Yun was taken aback, and the limited number of lower grade yuan stones on his body was only more than a thousand, and five hundred of them were handed over to Guo Jia along with the storage bag.

After all, if you want to get on the right track in the future, you still have to give rewards for the contribution of the deputy general!

As for moving the Pinyuan Stone Mine, Du Yun has no plans for the time being.

He frowned and asked, "A soldier's promotion from the first order to the second order is only an upgrade of one level, how can he need so many Yuan Stones?" ”

"Ding, there are two ways to upgrade the ladder, one is to upgrade as a whole, and the other is to upgrade alone; The number of militias in Xuzhou is 10,000, and the overall promotion requires 10,000 yuan stones! ”

"If you upgrade alone, each soldier will need to spend one and five lower-grade yuan stones to upgrade!"

"Huh? There is actually an extra half of the lower grade yuan stone for a single promotion, and if it is converted into a whole, it will directly be five thousand lower grade yuan stones...... Sizzle...... Boy! ”

After Du Yun calculated this number, he suddenly gasped.

And that's just a first-tier class.

Then he inquired about the promotion platform again, and sure enough, he found that the lower grade yuan stones required for the overall promotion of the second-order troops were mentioned as 50,000, and as for the individual, he needed 6.5 lower grade yuan stones.

For a long time, Du Yun thought that he was already very rich when he got a low-grade Yuan Stone mine, and he didn't have to worry about Yuan Shi for the time being.

But now, with the appearance of the promotion platform, he realized that he was really poor!

What's more, the promotion of the city seems to also require a large number of low-grade Yuan Stones!

"A low-grade yuan stone mine is still not enough, it seems that we have to find a new yuan stone ore source as soon as possible, I don't know if there is a yuan stone mine in the Nanyun Mountain Range?"

Looking up at the continuous mountains that had circled Nanshan City for more than half a circle, Du Yun's eyes flashed with anticipation, and he muttered to himself.

"Ding, the promotion platform has been opened, please select the promotion method of the class."

At this time, the sound of the mechanical system came from the elevator platform again.

"Promotion!"

It's just a half-yuan stone, and you can afford it!

Because it was a product of the system, with Du Yun's consent, the upgrade platform automatically connected to the system warehouse to extract two yuan stones and integrate them into it, and the five-mangyuan array rose up with a ray of light to envelop the soldiers.

Du Yun stood close, and he could clearly feel that a large amount of vitality in the Yuan Stone was absorbed by the ascending platform, and then the remaining little bit was integrated into the soldier's body.

The promotion didn't last long.

After the light faded, this Xuzhou militia soldier still belonged to the Xuzhou militia, but he became a second-order elite soldier!

Strength quadruple!

"Thank you, lord!"

After stepping down from the promotion platform, the soldier suddenly knelt on one knee and said loudly with excitement on his face.

Du Yun waved his hand and said, "You go down first." Then he called all the remaining nineteen soldiers who came behind him, and all of them were promoted in two parts.

This time it cost him eighty lower-grade Yuan Stones!

However, seeing that the spirit of the twenty soldiers in front of him had doubled compared to before, and their fighting spirit was high, Du Yun still showed a satisfied smile

"Hehe, the fourth day after tomorrow and the fifth day after tomorrow, I didn't waste my toss in vain!"

"Lord, it seems that you have not only added new soldiers this time, but also obtained great treasures!" At this moment, a voice full of surprise suddenly came from a distance.

Du Yun looked back and found that it was Guo Jia.

Soon, Guo Jia came over.

His gaze first swept over the twenty soldiers standing here, then he saw the high platform on the platform, and asked, "What is this, is it related to the improvement of their strength." ”

When he came over just now, Guo Jiake saw the soldier who was training and patrolling on his own.

Although they looked like the same class of troops as the twenty soldiers in front of them, their strength was all one order lower!

Naturally, this peculiar platform also attracted Guo Jia's attention.

When Du Yun heard Guo Jia's inquiry, he didn't hide it, he explained the information of the promotion platform in a little detail, and at the end, he also revealed his helplessness about the lack of Yuan Shi!

"Lord, in fact, you don't have to be entangled, doesn't that Yuanshi Mine have the heart of Yuanshi, so that you can first mine a part of Yuanshi from it to concentrate on improving the strength of some soldiers!"

"At the very least, you have to gather a hundred strong guards for the lord first, otherwise that guy will run to the barracks every day to harm the recruits!"

After listening to the lord's story, Guo Jia said very easily.

Then, he seemed to think of something, and suddenly said: "In addition, Nanshan City has basically been assessed, should the lord use the Dingcheng plate to search for other nearby cities?" ”

"Well, you're reminding me that maybe a city is near us!"

Hearing Guo Jia's words, Du Yun's eyes suddenly lit up, and he nodded.

Immediately, he no longer bothered about the matter of upgrading to the platform, but with a wave of his hand, he took out the Dingcheng Disk that had been in the system warehouse.
