The two exchanged for a while, and then Naofumi Iwatani turned and left.

Although he came to repay the favor, this favor was indeed repaid, but he learned about the ore refining from Lu Xia again, and he felt as if he owed another wave of favors.

"Why can't this favor be over?"

With such depression, Iwatani Naofumi left the warship and walked in the direction of the main island town.

cabin room.

Ryusha was still sitting on the edge of the bed, her eyes fixed on the enhanced icon at the top right of the view.

"The first is proficiency energy enhancement."

Ryusha found some forms that had been fully mastered but could not be used, such as some forms with weak stats at the beginning and useless equipment buffs, reset them, and then obtained a certain amount of proficiency energy.

It is worth mentioning that the proficiency of each form is 100, and as long as you reach 100, it can be said that the proficiency is full.

But when converted into energy, it can only be converted into 100, when the proficiency of ordinary weak forms is converted into energy, you can only get 100 proficiency energy, and some stronger forms can be converted to 200, 300 energy points, if it is the form of a three-headed demon dog, there are as many as 1000 energy points transformed.

Then, Ryuxia injected all these proficiency energy points into the Ghost King Bow form, and then the Ghost King Bow icon on the weapon book flashed.

"Ghost King Bow: C→UC!"

"Oni King's Bow (UC): Ability unlocked...... Equipment Buff: Fixed damage granted! Special Skill: Bow of Super Change! Arrows of Domination! ”

No new skills appeared, but the word UC appeared after the words Oni King Bow.

Lu Xia clicked on the help instructions, checked the relevant information, and then understood.

In the proficiency energy enhancement method, the initial form is only C, that is, the ordinary level, and with the injection of proficiency energy, it can be upgraded to the UC, that is, the unordinary level.

If you continue to level up, there are R (rare), SR (super rare), SSR (special super rare) and so on, but each level you increase will double the proficiency energy required.

Ryuxia has already consumed 10,000 proficiency points to upgrade the Ghost King Bow from C to UC, and all the proficiency energy of dozens of weak forms has been extracted, but the effect is also very gratifying, after the rarity is increased to the UC, the performance of the Ghost King Bow has been directly doubled.

Ryusha extracted all the proficiency energy of some other forms that could not be used, and then upgraded the Ghost King Bow to the R level, doubling its performance.

But at this point, the proficiency energy of the weak form is almost exhausted, and if you want to continue, you can only extract the proficiency energy of some relatively good forms.

But if all the proficiency energy is extracted, it will cause the equipment buffs of these forms to turn back to limited buffs, of course, on the whole, the advantages still outweigh the disadvantages, after all, the improvement of the Ghost King's bow form is obvious to all.

"It's okay, anyway, the proficiency of the weak form has only become 0, and you can continue to brush it after that, and you can continue to feed it to the ghost king bow form after the brush is full."

When the mastery is full, the equipment buff becomes a permanent buff.

The proficiency is then reset, and the equipment buff is reverted back to a limited buff, infusing the mastery energy into a powerful form.

Brush the mastery again, the proficiency is full again, the equipment buff becomes a permanent buff again, and then the proficiency resets again...... This will create a cycle, in other words, as long as you spend a little time, you can use proficiency in a circular way.

Ryuxia cleared his mind in his heart, and then extracted all the proficiency energy of some other forms that he didn't really need, and stacked the Ghost King Bow directly to the SSR level, and his performance was doubled again.

"It's so strong...... In this way, I am afraid that all the four dimensions below the bow ladder will reach EX, and it will be much more than the ordinary EX. ”

Ryusha clenched his fists, and with the blessing of the performance of the Ghost King's Bow, he even had the illusion that he could lift a small mountain.

If he meets Parson Lipu again, with the power of the Ghost King's Bow, he can definitely knock her away with one punch.

At this point, he didn't know what level of his strength had reached, after all, it couldn't be measured by pure numerical values...... Anyway, it's strong.

Of course, it is also limited to the bow rank, and even only in the case of using the Oni King Bow.

If you switch to another class, you will lose the blessing of the Legendary Bow, and his strength will still change back to the way it used to be, of course, because the level reaches level 100 and the basic value has also increased, the strength will still rise a lot, but it should not reach EX, it may be about 80 times or 90 times that of ordinary people.

In this case, the bow rank has become the strongest rank in Ryuxia at the moment.

"Don't worry, there's ore refining and soul enchantment."

Ryusha opened the drop icon, found some eligible ores, took them out, and then clicked on the ore refining icon, placing the ore on top of the Oni King's Bow.

Immediately after that, the Ghost King's Bow changed again.

"Refining success!"

"Oni King's Bow (UC): 1/50!"

There is a possibility of failure in ore refining.

But the first refining is a 100 percent success rate, and the second refining success rate is reduced to 90 percent, the third time it is reduced to 80 percent, and so on.

Ryu Xia glanced at the performance of the Ghost King Bow, and all the values seemed to have increased by about one-tenth?

The improvement is quite large.

Thinking so, Ryuxia used refining several times in a row, strengthening the Ghost King Bow to the level of 4/50, and each refining improvement can improve the performance by about one-tenth.

Then refining was used again.

"Refining failed!"

"Oni King's Bow (UC): 0/50!"

After the refining fails, the refining level drops back to zero.

Then, without hesitation, Ryusha refined it again.

It's okay, anyway, because he killed a large number of monsters, there are hundreds of thousands of various ores in his drop column, which can be completely consumed.

"Refining success!"

"Oni King Bow (UC): 5/50!"

Then, after the refining was successful, the level that had been erased before was also returned, so that the refining level reached 5 in one go.

After that, Ryuxia continued to use a large amount of ore for refining, and barely piled up the refining level to level 20, but after reaching this point, the refining success rate had been reduced to an outrageous level, and only one out of a hundred times was barely successful.

"It seems that it is necessary to increase the luck value in the future?"

Such a thought crossed Ryuxia's mind.

After all, his basic four dimensions are currently completely sufficient, and when he switches to the bow level, the four dimensions have reached the point of full ex.

In view of this, it would be too wasteful to use the opportunity to increase the basic ability value in the future on the basic four dimensions, so it would be better to use it to increase the luck value, and then use it to improve the success rate of refining.

After the refining level reached level 20, the performance of the Ghost King Bow increased several times on the basis of the previous one, and the blessings brought to Lu Xia became more and more terrifying.
