"20,000 Paradise Coins per level, within the acceptable range," Su Xiao muttered to himself in the skill upgrade warehouse.

Similar to the ability of goddess attachment to improve the lucky attribute, the upgrade cost is certainly not low.

Su Xiao had such an experience, that is, when he was in the Demon Castle, after he completed some of Alice's games, he got 1 lucky attribute bonus.

And after all the 'guests' in the Demon Castle escaped from the castle, the angry Alice confronted Su Xiao face to face, she didn't seem to do anything to Su Xiao, but actually forcibly stripped Su Xiao of the fortune that the game brought to her, for which Alice was punished by the Reincarnation Paradise.

As a result, all the 'guests' imprisoned by Alice escaped, and these 'guests' who had been imprisoned for hundreds of years and were full of hatred hid in the vast void, ready to take revenge on Alice, while Su Xiao lost the bonus of the lucky attribute.

This made Su Xiao know that this kind of 'permanent' bonus given by the strong man is sometimes unreliable, and in the final analysis, it is just a bonus.

Goddess attachment is different, although Su Xiao obtained this ability through the goddess of luck, this is already his own ability, and he needs to spend resources to improve it in order to gradually show the effect, even if the goddess of luck is in person, he can't strip Su Xiao's ability.

Because of this, Su Xiao is ready to invest resources in the ability of the goddess to be attached to it.

Standing in the skill upgrade warehouse, Su Xiao manipulated the virtual panel in front of him, choosing to improve the ability of the goddess's attachment, and now he still has 209,920 paradise coins left, which is enough to increase the goddess's attachment to Lv.10.

After choosing to improve his ability, the skill upgrade warehouse was running, Su Xiao's eyes looked around, he didn't have any obvious feeling, and the promotion of the goddess attachment was completely different from when the aura was released.

The Skill Upgrade Warehouse runs for five minutes and then stops.

[Goddess Attachment has been upgraded to Lv.2, yes/no continue to increase this ability.] 】

……

"That's it?"

Su Xiao raised his hands and looked at the changes in his whole body, there was no change, or the degree of change was too small, he couldn't notice it.

Su Xiao chose to continue to improve, and the skill upgrade warehouse continued to run.

[Goddess Attachment has been upgraded to Lv.3.] 】

[Goddess Attachment has been upgraded to Lv.4.] 】

[Goddess Attachment has been upgraded to Lv.5.] 】

……

[Goddess Attachment has been upgraded to Lv.10, but there are not enough Paradise Coins to continue to improve.] 】

The paradise coin fell like flowing water, and after only 9920 points left, the promotion was terminated, and Su Xiao checked the goddess's attachment ability.

[Goddess Love: LV.10 (Passive Skill)]

Skill Effect: Lucky attribute permanently +2 (increased by 1 point).

Hint: For every 10 levels of this ability, an additional 1 Luck attribute is increased.

……

Improving the goddess's ability to fall in love is equivalent to 200,000 paradise coins to buy a little luck attribute, not to mention losing or earning, from the current point of view, it seems to be a loss, but in the long run, it is very profitable.

As long as you are lucky when you open the legendary treasure chest, not to mention raising the goddess attachment to Lv.10, even if it is raised to Lv.30, it is also an additional harvest of three or two treasure chests to return to the cost, and then you can start earning blood.

Of course, Su Xiao has to plan for the long term, he is the development of the four attributes, and he needs a lot of resources to support, and obtaining resources sometimes requires not only strength, but also a certain amount of luck.

With not much of the Paradise Coin left, Su Xiao did not leave the skill upgrade warehouse, but contacted Bubuwang and opened the savings space of the adventure group.

Took out a paradise coin savings card with a face value of 500,000 from the storage space of the adventure group, the savings card disappeared in Su Xiao's hand, and the sales of skill scrolls were good, and the first batch had more than 500,000 paradise coins.

[You receive 500,000 Paradise Coins.] 】

With the replenishment of Paradise Coins, Su Xiao continued to improve the ability of the goddess to be attached.

[If you need to increase 'Goddess Attachment Lv.10', you need to consume 30,000 Paradise Coins, yes/no payment.] 】

The price increased, and Su Xiao still chose to increase, an hour later.

[Goddess Attachment has been upgraded to Lv.20.] 】

It's another level 10 upgrade, check the upgrade cost again, this time the cost has reached 40,000 Paradise Coins per level.

Half an hour later.

[Goddess Attachment has been upgraded to Lv.25, but there are not enough Paradise Coins to continue to increase.] 】

Needless to say, the cost of elevating the goddess's affection is very high, but fortunately, Bu Buwang sent a second paradise coin savings card.

[You receive 650,000 Paradise Coins.] 】

Su Xiao endured the pain and continued to improve the goddess's attachment ability.

[Goddess Attachment has been increased to Lv.30, yes/no continues to increase.] 】

When the Goddess Attachment ability reaches Lv.30, Su Xiao's Paradise Coins have 459,920 points left, and to improve Lv.30's Goddess Attachment ability, you need 50,000 Paradise Coins per level.

In this way, Su Xiao has to consider whether to continue to improve, which is a matter of resource balance.

If you want to improve, then you have to increase it by 10 levels at once, otherwise the gains outweigh the losses.

Goddess Attachment upgraded to Lv.40 can increase the Luck attribute by 5 points, plus the status of the European Emperor......

Su Xiao hesitated, his previous lucky attribute was 2 points, but now it has reached 6 points, and if he adds the state of the European Emperor, the lucky attribute has reached an unprecedented 10 points.

This level of luck attribute, if combined with certain abilities, can even be used in battle, Su Xiao has fought against this kind of enemy, without exception, this kind of enemy is very difficult to entangle.

Of course, Su Xiao is very good at his own fortune, and it is okay to use a high amount of luck attribute to open treasure chests, as for fighting, it may be that the time is not good, and it is extremely cheating.

At this point, after Su Xiao made this decision, he turned around and walked towards the outside of the skill upgrade warehouse, he still has other abilities to improve, sword skills, legendary-level gems, and new alchemy formulas are all not a small amount of Paradise Coin expenditure.

Improving ability should pay attention to balance, blindly improving a single ability, it looks beautiful in a short time, but it is not more than two worlds, and all kinds of drawbacks will appear, which is a mistake that only newcomers will make.

[Goddess Love: LV.30 (Passive Skill)]

Skill Effect: Lucky Attribute permanently +4 (increased by 2 points).

Hint: For every 10 levels of this ability, an additional 1 Luck attribute is increased.

……

It is worth mentioning that although the promotion cost of the goddess's attachment is very high, Su Xiao finally has the ability to steadily improve the lucky attribute, there is no doubt that the lucky attribute is the most difficult attribute to improve, without one, even the real attribute points cannot improve the lucky attribute.

Su Xiao returned to the exclusive room with a huge amount of money, Bubu Wang, Eminem, and Beni were all in the trading market, so it was inevitable that the exclusive room would be a little deserted, and the three goods were in the exclusive room at the same time, and it would be very lively here.

Su Xiaopan sat on the bed, and he took out 20 soul crystals (large) from the storage space, which was the result of how long he had accumulated.

After waiting for a while, Bu Buwang put a savings card of 100,000 paradise coins into the savings space of the adventure group, everything was ready, and Su Xiao chose to improve the sword master Lv.48.

[Yes/No to increase Sword Master Lv.48, if you need to improve this skill, you need to consume 250,000 Paradise Coins + Soul Crystal (Large) ×10.] 】

Of course, Su Xiao was promoted two levels in a row, because when the Sword Master reached Lv.50, he would have to face a choice.

One soul crystal after another shattered in Su Xiao's hands, and his eyes flickered, and the whole person was swept into the spatial whirlpool.
