Ye Yan's "Summoning Holy Flame" can only burn one skull at a time, and it is the one without pressure. According to the guardian of the Holy Flame Mountain, then those low-level Holy Flame ninjutsu masters generally had to burn such a skull, wouldn't it take three times to "summon the Holy Flame".

"Whew, the Holy Flame has run out of energy." Ye Yan, who was concentrating on burning more than a dozen skulls, only then got up to talk to Shui Nai, but when she looked at the few pyramid-like skull buildings around her, her happy smile immediately stiffened.

"Oh, let's practice later." Mina placed the last skull behind the top of another pyramid before carefully letting go of her hand and carefully examining the new work, which was more than half a meter tall.

“…… You're so bored. Ye Yan stroked her forehead and said.

"No, it's just that the ninjutsu I have on hand now is not suitable for use in this kind of crowded environment, otherwise I will definitely become famous." Mina glanced at the somewhat small figures in the sea of skeletons, these warriors who ignored the attacks of the skeletons were basically rampaging in this sea of bones, acting in the shortest path. And Mina's Flame Bomb or Wind Blade are ninjutsu that cannot be controlled precisely, and it is easy to hit those players who appear in the sea of bones from time to time.

"You can practice low-level ninjutsu, and the effect of those ninjutsu is also good." After Ye Yan finished speaking, she raised her hand and sent out a holy light bullet, shattering the chest of the closest skeleton soldier.

"This can't be done, to fight these undead creatures, you have to blow their heads, so that those dark forces can temporarily lose their support, so that they can be inactive." After saying that, Mina directly raised his hand and sent out a series of fireballs, which exploded the skulls of 5 skeleton soldiers in a row.

Since learning high-level ninjutsu, even Mina has begun to feel that the effect of low-level ninjutsu is too poor, and it can't keep up with the development of the times.

"Hmm." After Ye Yan answered in a nasal voice, she directly exploded the skull of another skeleton soldier.

"Then you practice this first, I'm going to experiment with something." After watching Ye Yan continue to practice that primary ninjutsu holy light bullet, Shui Nai suddenly thought of the charging problem of her "Yanlong Transformation".

When he came to Mina in the back, when he saw that there was no one, he threw a fireball technique directly at himself.

With a "poof", Minai looked at the black flame on the cloth armor, and then glanced at the charge rate, only to see that it had indeed risen, although it had only increased by 0.1%.

After that, Mina tried other fire-based ninjutsu, except for the explosion of flame bombs and the like, the rest of the ninjutsu such as Lianzhu Fireball, Flame Wall, and Flame Shield have been tried. All fire-based ninjutsu that act on oneself can make that charge rate increase, but the amount of that charge rate increase is different.

For now, Flame Wall, a ninjutsu with strong staying power, has the highest charge rate, which can increase by 0.1% per second, but it also does heavy damage to itself.

After summarizing the charge rate, Mina began to experiment with a combination of "Acceleration Technique" and "Flame Bomb". Just for the sake of safety, Mina added a lot of protection to herself at the beginning, such as wearing a ninjutsu robe with magic defense, and taking off all the equipment that added spirit and ninjutsu damage.

Looking at the extra states on the status bar, he dared to say that even if the flame bomb exploded in front of him, he still had the ability to survive.

If the skill combination is wrong, the most likely thing is that you can't use ninjutsu, but there will also be situations where you get out of control. If it's those low-level ninjutsu, it doesn't matter, after all, that one's power is limited, even if it hits oneself, it doesn't matter. But this is not the case with a big killer like the Flame Bomb, the power of the Flame Bomb is too strong, if it explodes in front of the ninjutsu master, it can definitely explode that ninjutsu master. Even Mina didn't dare to say that he could take the next flame bomb without preparation.

In the series of explosions that followed, Mina failed at least a dozen times, of which there were already 5 explosions, but only one explosion was in the open space in front of him.

Although he directly shattered the ice crystal armor on his body that time, and blew up half of the durability of several other defensive ninjutsu on his body, he finally succeeded in getting a flame bomb that was 10% faster in the last time.

In addition to starting at the same time for a combination of skills like this, now Mina has also found that the level of the original two ninjutsu must be the same. Just now, Mina's Flame Explosion Bomb was already two levels, and the acceleration technique was only 98% of the first level, and there were still a dozen times before it could be upgraded. And in the test just now, the acceleration technique was upgraded, and the result was successful.

"You're too messy, too." Ye Yan looked at the embarrassed Shuina, and then looked at the bombed woods in front of him, and said with some sighs.

"Don't talk about it, come here, I just found something in my backpack, I don't know if you can use it." After the failure of the experiment just now, Shuinai immediately took out the potion from the backpack, but Ye Yan's movements were faster than him, and the potion was not found, but he found a few stones from the corner of a backpack.

There is no way, Mina's backpack is too big, and there will always be something stuffed in the corner that is not cleaned up in time.

"This is a low-grade holy stone?" Ye Yan looked at the white stones in the palm of her left hand, which were only the thickness of her little finger, and said with some confusion.

"Yes, I found it before, but because there are too many impurities, all of them have not been able to be disposed of, you can see if it is useless. Oh, and I personally recommend that you try attaching the Holy Light Ninjutsu to it and see if it can have a strengthening effect. Mina said as she took out a few fire-type elemental stone fragments from her backpack and tried them out.

When Shui Nai reminded Ye Yan just now, she also reminded herself.

A gem with too many impurities like this is useless, and it will generally be taken back by NPCs for manual purification, but this process is limited by the empire, and there is no way to involve it with the player's current level.

But if it's used for this kind of ninjutsu enchantment, I wonder if it has any effect?

After some hard work, the result that Mina got was that these elemental stone fragments exploded directly on the palm of his hand, except for increasing the charge rate of that "Yanlong Transformation" by a few thousand points, there was nothing else.

"Don't try it, it turns out that this can't be used for enchantment, maybe there are too many impurities." Shui Nai saw that Ye Yan was still concentrating on studying the low-grade holy stone in the palm of her hand, and from time to time she changed the holy stone to the other hand, so she immediately interrupted her research.

"Do you still have it? I've found that it replenishes the energy of the flame. Ye Yan happily looked at the Holy Flame symbol on the back of her hand that began to emit a faint halo, and at the same time, there was a cloud of sand like sand in her open palm, and the Holy Stone had long since disappeared.

Shui Nai directly pinched a handful of scraps from her palm, and found that these were all impurities of the holy stone, and it seemed that the energy in the holy stone was directly absorbed by Ye Yan.

When Ye Yan saw that Mina was still planning to pinch up another handful of unstudied, she quickly poured all the pieces in her palm on his hand. She didn't want to be poked with her fingers anymore, it made her feel itchy, and there was a paralyzing feeling that made her very uncomfortable.

"Well, it's not much, but I have the skill to dig, as long as you know that this kind of holy stone is produced there, I can make a cameo appearance as a miner for a few days." Mina flipped through her backpack again, but she only found a dozen low-grade holy stones.

"I haven't heard of a holy stone mine in the Elemental City, but there are several large mineral deposits in the imperial capital, but they are owned by the state." After Ye Yan patted the scraps off the palm of her hand, she took all the stones handed over by Shui Nai and put them in her backpack as a backup.

"By the way, are you interested in practicing love skills?" Shui Nai suddenly stopped Ye Yan, who was walking towards the Skeleton Pyramid, and he had been thinking about the matter between the combination technique and the love technique just now.

For now, combos should be a skill that can be used by all classes, but not many people should know about it. And the love technique should be the specialty of the ninjutsu master's profession. After all, only the outward attack ability of the ninjutsu master profession can meet the conditions for the use of the love skill.

"Sentimental skills?" Ye Yan immediately turned around, and her long hair was also thrown in a big circle under inertia.

"That's ......", Mina directly told her and Miyuki what happened in the Trial Forest.

"Then what do you want me to do, do we cast ninjutsu at the same time?" Ye Yan knew that Shui Nai liked to do things that others couldn't think of, so she cooperated with him.

"This is not good, I have tried it before, and after the ninjutsu is released, it can't be changed, after all, we are not NPCs. But we can study from the characteristics of the ninjutsu's spell casting, and you need to use a staff for your 'Summoning Holy Flame', right? "Mina's thinking is quite jumpy, and studying problems in this way of discussion can provide him with good ideas. So when he saw the staff in Ye Yan's hand, he immediately raised this question.

"Yes, the Holy Flame Ninjutsu, like other ninjutsu, also uses a staff, but it is not projected from the staff." Ye Yan did not let go of the staff when she used the "Summoning Holy Flame".

"So be it, start with the staff." After saying that, Mina took out a general-purpose staff from his backpack that only added a dozen points of ninjutsu damage and stretched it out in front of Ye Yan.

And Ye Yan also understood his thoughts, put away his staff, and put his right hand on Shuina's staff.

"Holy flame, and fire-based ninjutsu. According to my thoughts, it should be based on fire-based ninjutsu, supplemented by holy flames, so after I summon the fireball, you will add the energy of the holy flame to it. Mina thought about it and said what he had in mind at first.

"Hmm." Ye Yan nodded, although one of the two used his left hand and the other used his right hand, the distance was a little close, so Ye Yan felt a little uncomfortable, and a layer of blush began to appear on her face.

"It's time." After Zuna watched the fireball on the staff appear, she said it in Ye Yan's private chat.

I saw Ye Yan take a deep breath, put her left hand to the side of the fireball, and at the same time began to use the skill of "Summoning Holy Flame".

At this time, the white flame in Ye Yan's hand drilled directly into the core of the Shuinai fireball, and began to disperse evenly on the fireball, coating the entire fireball with a layer of faint white light.

Then, Ye Yan slowly let go of her right hand at the signal of Mina, but the fireball with the light of holy light on the staff was still suspended on her staff. Finally, when Mina threw the fireball onto one of the skull pyramids, the fireball immediately spread down from the top skull like mercury, burning the top three layers of skulls, and wisps of black gas came out of all the burned skulls.

Like Shuina's fireball, although it can burn the skull, it can't dispel the black gas inside, and like this, it can only show that Shuinai and Ye Yan's love skills have been successful, and they have been named "Holy Flame Fireball" by the system.

"Hmph." It's just that at this happy moment, a voice full of anger and displeasure came from behind the two.
