Chapter 641: Wu Xiangning binds to the Ancient Singularity!

"It only improved by one grade?"

Seeing Yun Shen was not too surprised; even among World Wonders of the same grade, there are still distinctions in quality.

In Seeing Yun Shen's understanding, Gray grade usually implies negative effects, but the ability description of the Ancient Singularity did not mention any.

Although there might be hidden negative effects, Seeing Yun Shen still felt that the Ancient Singularity possessed its own uniqueness.

After all, this is a World Wonder that could gradually grow even before being imbued with an affix; it is truly too rare.

Furthermore, the advancement probability of World Wonders is low to begin with.

"Anyway, there is no limit to the number of uses, continue!"

Seeing Yun Shen took out another Legendary Item Advancement Card, "Advance!"

This time, the transparent crystal ball only bloomed with white light and did not change; when the light dissipated, it meant the advancement had failed.

【You used a "Legendary Item Advancement Card," the "Ancient Singularity" grade remains unchanged.】

"Tsk, continue."

【You used a...】

One Legendary Item Advancement Card after another was used by Seeing Yun Shen on the Ancient Singularity.

During this period, the Replication Black Box was also non-stop replicating Legendary Item Advancement Cards.

【You used a "Legendary Item Advancement Card," the "Ancient Singularity" successfully advanced to Green Superior grade.】

【You used a...】

【You used a "Legendary Item Advancement Card," the "Ancient Singularity" successfully advanced to Blue Rare grade.】

By the time he used the three-thousand-plus card, the Ancient Singularity had already advanced to Blue Rare grade.

But now that he had already used over nine thousand cards, it still remained at Blue Rare grade.

Previously, it was heard that if an Shi Shi World Wonder wanted to advance to Legendary via a Legendary Item Advancement Card, the probability was roughly one in one hundred thousand; this was a conclusion reached through statistics.

If advancing from Superior to Shi Shi, it might be one in ten thousand.

In fact, Seeing Yun Shen was also thinking that if it could advance to Shi Shi, it wouldn't be impossible to throw in a few tens of thousands more Legendary Item Advancement Cards.

At worst, it would just cost a few tens of thousands of trillion Source Crystals; gritting his teeth and getting through it would be fine.

But now, looking at the advancement probability of the Ancient Singularity, Seeing Yun Shen no longer had the thought of making it advance to Shi Shi immediately.

He only felt that if Wu Xiangning wanted to advance its grade in the future, he didn't know how many of his own World Wonders it would cost.

"Take it slow."

Gradually, ten thousand Legendary Item Advancement Cards were used up.

The grade was still stuck at Blue Rare.

This made Seeing Yun Shen somewhat discouraged, yet also somewhat unwilling to give up.

Damn it, having wasted so many Legendary Item Advancement Cards, if it couldn't advance to Purple Excellent grade, this thought really couldn't be satisfied.

Seeing Yun Shen knew that he was currently in a gambler's mindset because the sunk cost was too high.

But knowing is one thing; in the end, he gritted his teeth, "Try again, at most another ten thousand cards; if it doesn't advance, then forget it."

It was fortunate that the Replication Black Box had never stopped replicating, so they could be taken and used directly.

Originally, he had planned to replicate more to use on the three Rare-grade World Wonders just obtained in the territory; now, they could be used directly.

Finally, at the eighteen-thousand-plus card, Seeing Yun Shen finally saw that blue light turning from blue to purple!

【You used a "Legendary Item Advancement Card," the "Ancient Singularity" successfully advanced to Purple Excellent grade.】

"No child cries every day, no gambler loses every day!"

Seeing Yun Shen finally felt satisfied, and at the same time, discovered that this World Wonder had also birthed a new ability after advancing to Purple Excellent grade.

【Ancient Singularity】

【Type】: World Wonder

【Grade】: Purple Excellent

【Ability】: Source Devouring (Colorless), World Source (Purple), World Power (Purple), World Rule · Rudiment (Purple)

【Source Devouring】 (Colorless): Can strengthen its own World Source and World Rules by devouring World Source.

【World Rule · Rudiment】 (Purple): Automatically derives World Rules, can be used to comprehend skills, and can also be used against enemies.

After finishing reading this newly appeared ability, although Seeing Yun Shen had not yet experienced its actual effect, he could already imagine how much of a boost it would be to Wu Xiangning's strength.

Besides this, the Source Devouring ability imbued by the affix also underwent some changes after this new ability appeared; while devouring World Source, it could also incidentally improve World Rules.

Seeing Yun Shen did not rush to summon Wu Xiangning, but instead took out those three Rare-grade World Wonders from his backpack.

These three were exchanged by Seeing Yun Shen in the Exchange Space and were currently bound to the Territory Core; they were the 【Strange Array Eyeball】 which could increase the power of designated formations, the 【Golden Scarecrow】 which could increase crop yields within the territory, and the 【Slaughter Demon Sword】 which could be used as equipment.

"These three should all be quite ordinary; I hope they won't be that expensive... Advance!"

One Legendary Item Advancement Card after another turned into golden light, merging into these three World Wonders.

Earning so much money is meant for spending; incidentally, he would collect probability data on advancing World Wonders to use as a reference for the future.

Seeing Yun Shen was not willing to take just any World Wonder to devour World Source; those that could play a good role in territory development were naturally not to be treated as consumables.

Facts proved that Seeing Yun Shen's thoughts were indeed correct; it was simply that the advancement probability of the Ancient Singularity was too low.

These three World Wonders all easily advanced to Excellent grade, consuming only twenty-five hundred cards in total.

As for the higher Shi Shi grade, Seeing Yun Shen did not dare to attempt it; his small treasury could not withstand this level of consumption.

"Let's leave it at this for now; wait until the Replication Black Box advances to Legendary before considering continuing."
