Yun Lan certainly knew what Deferry was capable of. As a lich, especially a demigod lich, Deferry's personal combat power may not be much stronger than other demigod powerhouses, but when it comes to his role in war, other demigod powerhouses of different professions may not be able to compare with him!

But because of this, Yun Lan will have a lot of restrictions on Deferi, otherwise, once he is really allowed to play freely, I am afraid that it will not be long before this demigod lich will soon be able to pull up a huge army of undead!

In the face of the overwhelming sea of the undead, no matter how strong the Revenant Fortress is, I am afraid that it will definitely fall in the end. But this situation is not what Yun Lan is happy to see, although she really wants to capture the Revenant Fortress again, but it definitely can't be this way.

This time, Yun Lan attacked the Revenant Fortress, in addition to avenging her eldest brother Yun Feng, there was actually another important reason, that is, for the royal family of the Dark Sun Empire, to regain control of this Revenant Fortress! So in fact, Yun Lan's real goal this time was actually just the Frost Burning Legion, and she had never thought of completely destroying the important fortress city of the Revenant Fortress.

If De Ferry is allowed to act unscrupulously, even if she can really capture the Revenant Fortress in the end, I am afraid that when the time comes, all that will be left for Yun Lan will only be a pile of ruins! This time, if it weren't for the ambush arranged by the Frost Burning Legion in the canyon, it would really annoy Yun Lan, and I'm afraid she wouldn't use De Ferry's big killing weapon so quickly.

To be honest, if possible, Yun Lan really didn't want to use this demigod lich lightly. Although a long time ago, the life box of this lich was already in the hands of the Qinglong Yun family, but with the continuous improvement of the strength of De Ferri's realm. The restrictions of the life box on him are actually constantly weakening. When Deferry was just a legendary lich, the life box can be said to be definitely his lifeline, once something goes wrong with the life box, then Deferry himself will not be spared at all!

But now. Deferry has already successfully promoted from a legendary lich to a demigod lich, although for Deferry, the importance of the life box is still extremely important, but it is no longer a direct threat to his own life. Of course, if the lifebox was really destroyed, then Deferry would not have died with it, but he would have suffered a great deal of damage because of it. But it is absolutely inevitable, the strength has declined significantly, that is simply certain, there can be no suspense at all, Yan zhòng's words, Deferi is even very likely to directly lower the realm, from the current demigod, to the holy realm. Even the legendary realm is possible!

Other words. Although the existence of the life box is no longer a matter of life for Deferry, its importance is still self-evident. As long as this life box is still in the control of the Qinglong Yun family, there is no need to worry too much about the loyalty of Deferi. Unless someday. This demigod lich can go one step further on the basis of the present, ignite the divine fire, and become a true god. Otherwise, as long as he is still a lich, it will always be difficult to completely get rid of the restrictions imposed on him by the life box!

But if you want to become a god, how can it be so easy? Don't look at it in just a hundred years, Deferi has grown from the original legendary realm to the current demigod lich, such a speed of progress can definitely be called a god speed, in addition to not being able to compare with Yun Feng, even those personal disciples of Yun Feng, in terms of progress alone, most of them are probably just like this, right?

But in fact, the reason why Deferi was able to have such an improvement was not entirely due to his own talent and hard work, if it weren't for Yun Feng's gift, it would be absolutely impossible for Deferi to grow rapidly to this point in such a short period of time.

It's just that Yun Feng's gift is not without trouble, although the speed of the improvement of the realm of Deferi is indeed very amazing, but even if it is the same realm now, the real strength of Deferi is obviously a huge gap compared to those personal disciples of Yun Feng!

In fact, the reason why Yun Lan dared to take the demigod lich Deferi with her with confidence and boldness this time, in addition to mastering his life box, Yun Lan's own strength was also where her greatest confidence lies! Other demigod powerhouses may underestimate Yun Lan, a powerhouse at the peak of the Holy Domain, but Deferry, a demigod lich, would never make such a mistake!

Although along the way, Deferi has always been very deferential, but for this demigod lich, Yun Lan has never been able to trust completely and unreservedly, even if Deferi returned to the Qinglong Yun family, it has been more than a hundred years ago, whether it is in the blood-colored abyss or in the Qingyun plane, Deferi, the lich, can be said to have made a lot of contributions to the Qinglong Yun family, but Yun Lan has never really trusted this guy from beginning to end!

Yun Lan has always been convinced that if it weren't for the relationship between the life box, it would never be possible for De Ferri to be so honest and obedient, and as the strength of this lich's realm continues to improve, the restriction of the life box on him is also constantly decreasing, if you put aside the limiting factor of the life box, how loyal the lich is to the Qinglong Yun family, I'm afraid it is really a very doubtful question!

Therefore, for the demigod lich of Deferry, Yun Lan's attitude is to use it as much as possible, even if the situation is compelled, he must be restricted as much as possible, and he must not be given the opportunity to play freely, after all, for a demigod lich, it is really not too easy to play some tricks in secret, even if he has a life box in his hand, Yun Lan still does not dare to have the slightest negligence!

It turns out that Deferi is worthy of the name of the demigod lich, and in less than half a day, he easily controlled both ends of the forbidden mountain range and canyon, although the ambushes arranged by the Frost Burning Legion are also rare elites, but for Deferry, a demigod lich, it is obviously not enough to see.

Although it is said that there is no large-scale war in this place, coupled with Yun Lan's many restrictions, Deferi can use the corpse for the time being. Actually, there aren't many. If it were replaced by other necromancers, there might really be no way to quickly pull up a large-scale army of undead in a short period of time, but for Deferry, this is a problem. It's not really a big deal!

For a lich of his level, the materials for summoning the undead have long been more than just fresh corpse materials. Near the canyon, there has indeed been no fierce fighting in recent times, even if the front army of the Qinglan Legion and those ambush soldiers have indeed had some conflicts. But in reality, not many people died. But the Revenant Fortress here, after all, is a place where soldiers must fight, and the strategic position can be said to be quite important, in the past hundreds of years, the Heavenly Dragon Empire and the Dark Sun Empire, around this fortress, there have been countless tragic battles, although in the end, they basically failed to successfully capture the Revenant Fortress. But the number of soldiers who died because of this fortress is really not a small number!

As the only passage from the Screaming Plains to the Revenant Fortress. This canyon in the Forbidden Mountain Range has definitely buried the lives of countless warriors. Among them, most of them should be soldiers of the Dark Sun Empire, but the Heavenly Dragon Empire should have had a lot of casualties here. After all, it wasn't until Empress Laxis recaptured the Revenant Fortress for the first time. During this period of time in between, this Revenant Fortress had always been in the hands of the Heavenly Dragon Empire!

In this case, of course, the Celestial Dragon Empire will use the Revenant Fortress as a base to pass through this canyon of the Forbidden Mountain Range. Constantly attacking the Screaming Plains of the Dark Sun Empire, and the Dark Sun Empire is definitely not willing to be passively beaten, and counterattacks are naturally inevitable, so this canyon will inevitably become the focus of contention between the warring parties! Although the side with the Revenant Fortress is indeed relatively advantageous, but no matter what, casualties and sacrifices are still inevitable.

These warriors who have been dead for many years, and the necromancers who are not strong enough, I am afraid that they may not really have a way to use them, but for the demigod lich of Deferry, they are the ideal "raw materials". Although it is said that these soldiers have been dead for so long that most of the bones are already mutilated, if you follow the usual way of summoning the undead, even ordinary skeleton soldiers, I am afraid it will be difficult to summon them, and as for zombies or something, it is even more impossible. But for Deferry, it's not a big deal at all!

In fact, what Deferry really values is the souls of these fallen soldiers, so Deferry did not transform physical undead such as skeletons and zombies at all, but chose spirit-like undead such as ghosts and ghosts! Although it is said that the potential for evolution of undead without physical bodies is often much smaller, but for Deferry, it is not a big problem at all, anyway, he has no plan, and now he immediately makes an army of elite undead, anyway, just to deal with the errand that Yun Lan explained, it is almost enough to make a similar undead cannon fodder!

Moreover, in the special environment of the Forbidden Mountain Range, the spirit-type undead have another greater advantage, that is, the limitation of the terrain, for these undead, there is almost no great influence! Because of this, although the individual strength of these undead summoned by Deferry this time is actually not too strong, after all, most of them are transformed from the souls of ordinary fallen soldiers, even if they are strong, they are not much stronger, but in the special geographical environment of the forbidden mountains and valleys, these elusive souls are a great threat to those ambushers of the Frost Burning Legion!

Since they are undead, then naturally there is no need to worry about the consumption of the body, as long as Deferry is willing, these revenants can attack without interruption! And as more and more revenants are constantly awakened and transformed by Deferry, the pressure on those ambushers of the Frost Burning Legion is also getting bigger and bigger! Finally, before even half a day, these ambushers can no longer hold on, and have to give up the ambush attack against the Yunlan army and immediately return to the Revenant Fortress.

Now that the goal has been achieved, Deferi will naturally not rush to pursue, although the combat power of these revenants he summoned is indeed good, but the number is still limited after all, although there is no shortage of "raw materials" in the canyon. But in just half a day, even the demigod lich of Deferry, even if he tried his best, he couldn't summon too many undead armies to come out. What's more, how could Deferry not know about Yun Lan's restrictions on his jealousy. In this case, Deferry's every move naturally has to be restrained.

In fact, with these revenants summoned by Deferry, there may not be any problem in dealing with these ambushers of the Frost Burning Legion, but if you want to attack the Revenant Fortress, this bit of strength may not even be enough to plug between your teeth! Since it is called the Fortress of the Revenant, of course, it is impossible to be unfamiliar with the undead creatures, in fact, the biggest reason why this fortress is named is actually because of the fortress itself. For undead creatures, there is a huge restraint in nature!

Deferry himself. At the beginning, he was defeated by Yun Feng in the Revenant Fortress, and even his own life box fell into the hands of the Qinglong Yun family, so in a sense, Deferi is the real indigenous inhabitant of this Revenant Fortress! Deferry, of course, couldn't be clearer. Although this fortress has been trying its best to continuously strengthen this fortress for more than a hundred years, whether it is the Celestial Dragon Empire or the Dark Sun Empire, Deferry believes. No matter how strong this fortress becomes, many of the basic things of sin will never be changed lightly.

Of course, with the realm and strength of the demigod lich now, if he really lets go without any scruples, it is still not difficult to capture this revenant fortress, but judging from the current form, Yun Lan is obviously not willing to hand over this heavy task to him so lightly.

Although Deferry felt quite sorry for this, he still quite agreed with Yun Lan's ability, although the Frost Burning Legion stationed in the Revenant Fortress now could indeed be regarded as a strong army, but if Yun Lan really wanted to capture this Revenant Fortress, Deferry really didn't think that the Frost Burning Legion on the opposite side could really hold it!

Others may not know, but how could De Feili, who has been controlled by the Qinglong Yun family for hundreds of years, not know how strong the Qinglong Yun family is today! And as the most outstanding commander of the Qinglong Yun family, under the command of Yun Lan, it is absolutely impossible, only the power that is displayed now. Deferry believes that if Yun Lan is willing, let alone a revenant fortress, even if it is Dragon City, the capital of the Heavenly Dragon Empire, Yun Lan is absolutely sure that he can break through it!

"If it's just a Frost Burning Legion, it's really hard to hold the Revenant Fortress. After recovering to Yun Lan, Deferry, who was once again idle, didn't care too much, but in the heart of this demigod lich, he already had other plans, "But if the Frost Burning Legion can discover the true secret hidden in the Revenant Fortress, at that time, even if it is you Yun Lan, if you want to capture the Revenant Fortress again, I'm afraid it won't be so easy, right?"

Of course, Deferry knew that if Yun Lan really captured the Revenant Fortress, then for himself, he would undoubtedly miss a once-in-a-lifetime opportunity, and as long as Yun Lan could be allowed to return under the Revenant Fortress, then when the time came, his opportunity might come again!

No lich would be willing to put his life in the hands of others, even since he took refuge in the Qinglong Yun family, Yun Feng had indeed never treated him badly, otherwise, with the natural potential of Deferry, it would be impossible to advance from the original legendary realm to the current demigod lich in just over a hundred years!

But even so, De Ferri has never really had a sense of belonging to Yun Feng and the Qinglong Yun family, especially, as his realm strength continues to improve, De Ferri's desire to get rid of the Qinglong Yun family's control began to become more and more intense. It's just that this kind of thinking is well disguised by Deferry, because he himself knows very well that no matter how fast his progress is, even if he is now a lich in the demigod realm, but in front of that Yun Feng, his strength is probably even more inadequate than back then!

What's more, his own life box, after all, is still in the control of the Qinglong Yun family, to be precise, it should be in Yun Lan's hands now, but De Feili himself knows that although he is a demigod realm, but when it comes to real combat strength, he may not be able to beat Yun Lan at the peak of the holy domain! What's more, by Yun Lan's side, there are also guards from other demigod realms, and with De Ferri's strength, if he wants to take back his life box from Yun Lan's hands, this is basically an impossible task.

If Deferry is allowed to give up the life box, although with his current demigod realm, although it will not endanger his life, once something really goes wrong with the life box, Deferry's own realm strength will definitely suffer an unprecedented heavy blow, and such a huge price, unless he really has no choice, otherwise, Deferry will definitely not make up his mind lightly.

However, for Deferry, there is a chance now, a chance for him to completely get rid of the Qinglong Yun family control! And in order to achieve his goal, Deferi must personally enter the Revenant Fortress, but now, Yun Lan directly refused to let him participate in the battle against the Revenant Fortress, and in desperation, Deferi had to take other actions, fortunately, in the canyon before, he had already arranged a secret hand in advance, and next, it depends on what kind of reaction the Frost Burning Legion will have.
