Maybe it can be used.

The Frost Dragon is the "big killer" among the four forms of the Bone Dragon. It is also the most powerful killing god in the undead army. It has almost a devastating killing effect on all middle and low-level enemies.

For it, the freezing effect is just an incidental skill to prevent the enemy from disintegrating and improve the killing efficiency. It is not very powerful, and if you are facing a powerful being of the same level, you can only rely on luck to completely freeze the opponent.

, and generally you can't do anything when it's frozen, and you're basically in a state of dryness.

However, after being strengthened, the frost dragon's breath attack always has a 50% effect of soul flame burning.

Those who have a 10% chance of dying directly are not counted. Others, whether they are slowed down by the impact of the ice attribute or unlucky enough to be "frozen" directly, will all suffer continuous and continuous damage!

Those who slow down like a snail will have blue soul flames attached to their body surface, while those who are frozen are even more unlucky. There are soul flames jumping around in the entire huge ice lump! But for frost

For the giant dragons, the soul flame beating under the ice armor is a kind of protection, but for them it is the deadly fire of death.

After actual combat testing, this special effect improvement is amazing!

The frost dragon was originally a killing weapon, but now it can kill people even more efficiently!

Even if those fourth- and fifth-level opponents were not sprayed to death, their lives would be short-lived due to the slowness and additional damage caused by freezing.

It can be said that the upgraded Frost Dragon has the amazing power to control the field with one force, cripple it with two, and clear the field with three against all units below level five!

And the time between these three mouths is only a few breaths, which only takes ten seconds! If the opponent's position is more dense, it will be easy to sweep away 120 or 30 people in these ten seconds!

This effect was so strong that even Xue Lan's pretty face flushed with excitement at the time, and the little assassin who reported next to him was jumping up and down excitedly while eating dinner, as if the chair was covered with nails.

Liu Yifei was stunned upon hearing this. He didn't expect that in addition to the Dracolich, even the Frost Dragon had such a big improvement.

In addition to the astonishing improvement in the face-to-face killing effect of the Frost Dragon, due to the continuous damage bonus of 50% of the attack power, it is no longer as confident as before when facing the same high-level opponents.

Originally, the Frost Dragon was a weird, high-defense, surface-killing unit, just like an oe mage wearing heavy armor. Its ability to attack the enemy was slightly weaker.

However, in the experiment under the auspices of Xue Lan and the others in which the Frost Dragon challenged the Abyssal Dragon, the Frost Dragon's winning rate unexpectedly increased to about 60%!

Because the opponent actually loses blood continuously even when frozen!

Although the additional damage of 50% of the damage effect is not so fatal to beings of the same level, as long as you are lucky enough to trigger the freezing effect a few times, you will almost be sure of victory! Because the opponent will always be in a state of blood loss!

At the same time, Xuelan and the others also tried a three-on-three trial between the Frost Dragon and the Abyssal Dragon. The result of the ten-on-ten simulated battle was that the more Frost Dragons there were, the higher the winning rate was, and the losses on one's side were getting smaller and smaller!

In the end, almost all the opponent's units were frozen, and then lost blood like crazy. Every time someone thawed, they would be immediately attacked by all the frost dragons! In this way, there was almost a 100% chance of falling into the frozen state again.

Almost solved!!!

This result was so amazing and shocking. At that time, Liu Yifei was so shocked that he was speechless. He could only silently sigh in his mind that this "gift" given to him by God Sandro this time was really amazing~

Currently, there are nearly a thousand frost dragons in Liu Yifei's Hidden Front troops. If all these are upgraded,

Okay~

At least from that moment on, the Frost Dragon and the Dragon Lich have become Liu Yifei's strongest strategic force. From now on, using this force in battles below the inter-state level is simply considered a force.

What a blasphemy

(In this paragraph, you may think that I have made these two top-level undead dragons a little too strong, but in fact, according to my plan, the bone dragon may be the weakest among the seventh-level soldiers, but that is because the undead dragon

The special effects have not yet been exerted. And in the seventh-level high-grade form, especially in the top form, the strength between the various races should still be balanced, otherwise the undead tribe would not be able to share the world equally with the other seven tribes without high-end leaders.

Furthermore, seventh-level high-grade, top-level mercenaries are definitely not weaker than ordinary spiritual-level heroes in terms of basic attributes, and are even better than some weaker spiritual-level heroes. Their weaknesses are always intelligence and soul.

In terms of privileges, there is no learning ability, no adaptability, single attack method, no "trick" to win the game, etc.

But this time Gregory's "Guardian" special effects have been improved on this shortcoming. The improvement is amazing. You can imagine that the Dracolich hero and the Frost Dragon hero are the top seventh level heroes.

A hero in the form of a hero, compared to ordinary ones,

Even the current Gregory in the form of a bone dragon is much stronger. I am afraid that his basic attributes are not weaker than those of ordinary legendary heroes. In such a comparison, in fact, the mercenary Dracolich and the Frost Dragon have

The performance can only be "fair")

Compared with the qualitative transformation and sublimation of the top frost dragon and dracolich, the improvement effect of the eighth-grade ghost dragon is much weaker. After all, both in terms of basic strength and soul power, the first two are far from unrealistic.

The eighth-grade ghost dragons undergoing their second transformation are comparable, but the current embarrassment is that, at least in a short period of time, Plague City cannot support the evolution of these ghost dragons.

The only few ghost dragons were produced by the territory or obtained through tasks, and then were promoted to the fourth level with the support of the territory. They were then promoted to the sixth level in one go through the "Soul Tempering Array", and then continued to the eighth level.

.

It's a pity that Plague City Shangfa has mastered the conditions for bone dragons to break through the first and second advancement restrictions, so the ghost dragons' strength is only limited to this, and they cannot even continue to improve in a short period of time.

The eighth-grade ghost dragon has mastered the ability of death breath, and due to the improvement of the soul, its breath has shown a bright blue color, which is obviously caused by excessive soul power. However, the breath itself is

The attack range has not been increased, and there is not even a continuous burning effect similar to that of the Frost Dragon. The attack effect has only been increased by 10%, which has to be said to be a big pity.

When talking about this matter, we have to mention another big "good news" that happened in the territory recently, that is, after Huang Huangquan returned to the territory and resumed his service, he finally made a breakthrough contribution——

With the support of this girl's tens of thousands of failed attempts and countless crazy ideas, she actually mastered the conditions for promotion to become a corpse witch mercenary!

It can be said that this was even unexpected by Liu Yifei!

Ever since they learned that there were so-called "promotion restrictions" on mercenary advancement, Liu Yifei and others tried every means possible to break through the blockade set by this system.

There are no restrictions on low-level soldiers. All lords can use their free military merit to evolve and improve them at will. Once they reach the middle level, although there are troublesome promotion restrictions, it is obvious to all that after the mercenaries break through the promotion line,

.There will be an explosive improvement in strength, and even mercenaries after the intermediate level may have powerful talents such as blood-sucking symbiosis, soul control, permanent invisibility, etc.!

Therefore, even though the "promotion restriction" is very troublesome, players all over the world are still trying to solve this problem. It is conceivable that once someone solves these problems first, they will definitely be able to get it in their hands.

His combat power has been transformed, and he can become famous all over the world, becoming a "celebrity" that several powerful lords of the same race are competing to hire.

However, even so, limited by the strength of the territory itself, the current mainstream lords are still focusing on overcoming the promotion blockade of the third-level mercenaries, and a small number of powerful lords are conquering the fourth level.

After all, this thing requires a large number of mercenary teams for experiments. Furthermore, various strange restrictions require huge funds to support various powerful experiments, and even if someone breaks through the blockade, generally speaking, they will not

If you tell others casually, you will only carefully hide it to continue to improve your own strength. So if you want to say what problems in the current game world are "difficult to the whole world", this is probably the case.

The progress of Plague City in this regard is quite astonishing. The conditions for promotion of third- and fourth-level mercenaries have been completely overcome. The large amount of free military merit accumulated in their hands can be quickly converted into strength, further consolidating their status as the strongest in the world.

But one must know that even Liu Yifei dare not ignore the strength of the fifth-level corpse witches of the ghost clan. The inability to overcome the promotion blockade of the fifth-level corpse witches has always been a huge obstacle to his growth. Liu Yifei has not dared to slack off for a day.

In fact, Liu Yifei already has two ways to "solve" this problem.

After Liu Yifei's inquiries, it has been clarified that although these "promotion blockades" cannot inquire from other lords, they can directly seek support from their own kings. However, this support is not priceless. On the contrary, the consumption required is so high that it is necessary for the country to

The level of contribution far exceeded Liu Yifei’s estimation. I think

Liu Yifei must at least go through a vast battlefield similar to the previous "Ghost War" again before he can accumulate enough capital to "inquire" from the old vampire. This is a condition that has been classified as "confidential" by the goddess of the world, even if it has always been

Toradre, who took great care of Liu Yifei, did not dare to cross the line without permission.

The first condition is very harsh, but Liu Yifei’s second method is to use the "Soul Tempering Array"~

Although the effect of this thing is rather deceptive. It can only be used once for each target and cannot directly push high-level units to the extreme. However, its effectiveness is sufficient for mid-level units.

The only troublesome thing is that the "power" of this magic circle is too strong. Intermediate units may not be able to withstand the end of the effectiveness of the magic circle. This is true even for fifth-level and fifth-grade great corpse witches. Successfully advance and fail to die.

The ratio is half and half. If you want to take a shortcut with this method, you can only spend money! It will be a waste!

Fortunately, Liu Yifei still has a large number of corpse witch lords and chaos lords at his disposal, and the sixth and seventh level soldiers produced in the territory also need a large number of soul crystal fragments for future promotion, so Liu Yifei has not made any plans for the time being.

Otherwise, half of these corpse witches will die in their own "laboratory" before they can go to the battlefield.

It was a fluke. It seemed that the recent sight of Liu Yifei immersed himself in the "laboratory" touched the girl Yu Huangquan, and she actually found seven or eight professional gaming girls who were supported by the Star Battle Spirit Studio. These girls

Already in other places

The clan is responsible for setting up the studio stronghold, but now the studio has in-depth cooperation with Plague City. The other clans basically only have some groups left to deliver messages. All the main personnel have changed clans and come to Plague City, so the levels are relatively high.

Low, you have to practice from scratch.

It wasn't about fighting anyway, so Huangquan simply found this group of girls. A group of people got together to experiment with the promotion of corpse witches.

After a long period of struggle, they were able to break through a promotion blockade without even guessing!

That is, after placing the fifth-level corpse witch in the lord's magic tower and the mercenary building "Mausoleum" (the recruitment building of the fifth-level corpse witch) for a period of time, it can actually get the promotion permission and become the fifth-level corpse witch.

The sixth-grade "Cursed Corpse Witch" - takes the route of "Corpse Witch Lord"!

When this news was confirmed, Yu Huangquan was so happy that she almost jumped out of the seven or eight-story Lord's Castle of Plague City!

After further careful consideration, they actually discovered a gratifying "shortcut"!

That is, if the blood of the fifth-grade "Great Corpse Witch" is emptied, and then allowed to recover naturally in the lord's magic tower and mausoleum, the time to break through the limit can be greatly shortened!

It can be said that we were able to try this method at the beginning by referring to the example of third-level undead being promoted to ghosts (letting fifth-level earthbound spirits lie in the cemetery), but the key difficulty is that the corpse witch not only has to lie in his own nest.

Going to the Lord's Magic Tower to hang out is relatively unpopular. The basis for the sisters who thought of this is - can't high-level corpse witches be able to cast spells and summon? So what if you don't go to the Magic Tower to learn magic?

For this seemingly reasonable but bizarre idea, perhaps only girls’ eclectic and unconstrained imagination can hit the mark, right?

As for the subsequent "shortcut" improvement plan, it was Yu Huangquan who came up with it.

After determining the conditions for promotion, she guessed that such an arrangement may be because corpse witches are spellcasters, so promotion requires more magical power. However, they lack the ability to actively learn, so they can only passively stay in the magic tower.

After absorbing it, who made it naturally filled with a lot of magic? After all, the Lord's Magic Tower is connected to the territory's public magic pool.

And the reason why we still need to lie down in the mausoleum

Please, pay attention to the ultimate name of this route - "The Corpse Witch Lord"!

If you don't go back and chat with the other little corpse witches and show off, what kind of "corpse witch lord" you are? So of course you have to go back and hang out!

In order to increase the speed of the Great Corpse Witch's "passive absorption of magic power", the only way that Huangquan could think of was to cripple them, and then let them stay in the magic tower to recover naturally. However, he did not expect that they would be able to "kill" them in one fell swoop.
