Strengthening the furnace, for the enhancement of skills, Du Hei's experience is that the level of skills, when the enhancement reaches the purple limit, is not the key.

The creatures it summons will have the characteristic of absorbing the spiritual power of heaven and earth on their own and improving their own strength.

Other words.

Even if the skill of summoning poisonous bees is only a first-order, and the subsequent skills are only summoning poisonous bee kings up to the fourth order, which is a garbage skill in garbage.

It's completely a skill that Du Hei uses as a mat.

But now, after reaching the quality of the purple limit, its combat power will not be inferior to that of a single giant barbarian.

And, more critically.

Upgrading the Fortified Furnace requires 20 items of Purple Extreme quality.

This thing can also make up a number.

So it's not too much of a loss.

"Whew, keep reinforcing it. ”

Du Hei adjusted his mentality.

His gaze gradually calmed down.

Continue to intensify.

The process is repeated.

However, Du Hei didn't feel bored.

Every time I strengthened, my mood fluctuated and excited slightly.

Especially, when the sixth-order skill was thrown in, that kind of desire was even more urgent.

After all, although the skill is strengthened to the purple limit, there is not much difference.

But what you must know is that these skills of the sixth order are all specially matched by Du Hei.

It is able to form a lineup combination and strengthen combat power.

It can make summoned beasts with extremely high attack strength, such as giant barbarians, make up for the weakness of speed.

Therefore, the importance is naturally higher.

However, no one can say for sure about the intensification.

After a full half an hour of tossing, the results were remarkable.

It was also successful in strengthening the other three skills in addition to the skill of poisonous bees to the quality of the purple limit.

But...... There is only one skill that Dublack needs.

The rest is a mess of skills.

If it was usual, Du Hei would definitely have a black line on his face.

But now, Du Hei's expression was still calm, or rather, a little numb.

Indeed, after such a long period of intensification.

It's not boring, but the whole person seems a little numb.

The number of iron ash mines is still very large.

Starting from the white quality to the purple quality, the average strengthening of one hand costs one hundred and twenty iron ash ore.

The cost of one enhancement is about five seconds.

Twelve times a minute of reinforcement, half an hour, three hundred and sixty times.

The cost of iron ash ore is only tens of thousands.

But it's different from selling enhanced weapons before.

Before strengthening the weapon, Du Hei can use the passive skills upgraded by the enhanced furnace, and he will not fail, basically playing with the cat, and strengthening at the same time.

But now, because of the rush to the purple quality, there is a chance of failure, and the feeling is different.

Fortunately, Du Hei's patience has become much stronger after the original escape incident.

Reinforcement is still underway.

In one hour, about 100,000 iron ash ores are consumed.

At present, there are more than 5 million iron ash mines, and it will take nearly two days to consume them.

Of course, this premise is that Du Hei's face is really black to strengthen the successive failures.

According to his estimates, this efficiency is down.

Twenty pieces of purple extreme quality have been enhanced, and at most it will only take about two hours at most, which should be able to upgrade the furnace.

After upgrading, it may be possible that the purple limit quality will be able to have a guaranteed existence like the previous blue limit.

After all, he had three skills that were purple limits before, and now he has four more skills, and the current data has seven.

According to the calculation of three in half an hour, there are still thirteen purple limits left.

That's just over two hours.

Du Hei simply pinned his hopes on the furnace upgrade.

He calculated that there were a total of nine sixth-order skills he wanted to strengthen, plus some skills he had prepared.

Among them, the main battle type, in order to match the "demonization" blessing of the giant power demon lineup, it is necessary to strengthen the skills of the two demon systems.

And then the rest, among the sixth-order skills learned, in order to make up for the shortcomings, Du Hei almost all chose the healing class, support class, and ranged attack class.

These skills, before the seventh order, Du Hei's goal was to be at least the purple limit.

Counting the upper limit of the quality that can be increased after the furnace is upgraded, and three higher-quality skills have to be strengthened, some mats will definitely be needed.

Plus the weapon Bagua Lupine fan.

It is estimated that more than 100 pieces of purple extreme quality are needed.

In this case.

Relying on the current mid-level furnace alone, I'm afraid that it will really have to be strengthened for a day and a night.

Now Du Hei only hopes that after the furnace is upgraded, it can increase the efficiency of the enhancement.

While thinking about it.

The action of strengthening did not stop, and the iron ash ore was frantically consumed.

And the purple quality items are also strengthened successfully.

Then it becomes the purple limit.

I have a plan in mind.

Du Hei will not be entangled in the so-called mat is not a mat.

Reinforcement and that's it.

Randomly select skills to strengthen, no need to deliberately arrange the order, in the case of changing skills, the efficiency is faster, and it takes about three seconds to complete a reinforcement.

Finally, about two hours later.

Duhei is carrying out a mechanical intensification operation.

At this time, a voice sounded in my head.

"Ding, more than a thousand times of reinforcement. ”

"There are more than twenty Enhanced Purple Extreme quality items. ”

"The furnace upgrade conditions have been met. ”

"Do you want to upgrade the furnace?"

This voice, for Du Hei, is like a heavenly sound.

After being slightly stunned, Du Hei immediately made a choice.

Upgrade!

How could it not be upgraded!

There was a silent thought in my heart.

At this time, the furnace in front of me suddenly changed dramatically.

The furnace itself, which had been originally copper-colored, gradually became shiny and translucent at this time.

A touch of silver-white rendering up.

In just a moment, the copper-colored furnace turned to silver.

If the original furnace is black and iron in color, it looks tattered, and the upgraded intermediate furnace looks just ordinary, then the upgraded furnace at this moment looks much more high-end and atmospheric.

With the change of appearance.

At this time, the voice sounded in my heart again.

[Master]: You who are crazy about using the furnace have already mastered most of the essence of enhancements, and in the next enhancement process, enhancements below orange quality will increase the success rate by 30%.

[Advanced Enhancement Furnace]: Increases the maximum enhancement quality to orange.

[One-click forging]: You can choose the one-click forging function, which can directly enhance the item to the orange limit quality, but correspondingly, the item consumption required for each stage of the enhancement will be calculated according to the lowest chance (can be used once every seven days)

The upgraded furnace made Du Hei smile all over.

In addition to the speculation, the upper limit of enhancement has been increased, and the latest master feature has fully increased the success rate of orange by 30%.

Originally, it was only a few percent success rate enhancement to the purple limit quality, but at this moment, it has increased by 30% with white, and it has directly become more than 30%.
