Let's take a look at the Holy Dragon City side again.

It has been a month since the start of the plan to lead the water to the east, and in the past month, the Holy Dragon Realm has undergone great changes, and a large number of wild monster gathering points have been wiped out by the undead creatures that suddenly appeared, and the entire Holy Dragon Realm has become a paradise for the undead.

At this time, the undead creatures in the Holy Dragon Realm were no longer just skeleton soldiers, a large number of zombies, mixed in the ranks of skeleton soldiers, were moving slowly in the direction of the Holy Dragon City and the underground passage.

In the sky, one after another black shadows floated by, as well as the flying ugly bats, this is the third and fourth order of the undead, ghosts and vampires, in just one month, the undead creatures that have emerged from the cave have undergone great changes, and their strength has also changed dramatically.

Compared with the changes in the undead, Jin Tao has not been idle for a month, from time to time with the holy dragon, attacking the skeleton soldiers around the lair of wild creatures, and collecting the alchemy circle of the lair, but this action, after the ghosts and vampires began to appear, could only give up helplessly.

With the appearance of these flying undead creatures, the pressure on the defenders of the cliff platform has become very great, and even Yin Spirits and vampires have attacked the platform at one time, but fortunately, there are a large number of holy dragons and poisonous dragons, facing the undead creatures in the air, a dense burst of dragon breath spewed over, and with the large-scale magic attack of the purple dragon, it stabilized the position.

Seeing this scene, Jin Tao couldn't help but breathe a sigh of relief, he didn't dare to imagine what kind of consequences would be caused if those ghosts and vampires really attacked the cliff platform.

And in just such a short period of time, there have already been large-scale fourth-order creatures appearing, Jin Tao can't imagine that if it takes a while, there will be an overwhelming number of seventh-order undead, the bone dragon, joining the team attacking the cliff platform.

Under this tremendous pressure, Jin Tao made a decision to abandon the cliff platform, retreat to the Holy Dragon City with all troops, and block all the passages leading from the platform to the castle, completely cut off the offensive route of the undead army, and at the same time began to expand the scale of the labyrinth in the passage and increase the strategic depth of the Holy Dragon City.

As Jin Tao abandoned the cliff platform and sealed the passage to the Holy Dragon City, the undead creatures who occupied the cliff platform lost their attack target and began to rush towards the underground passage.

In the hall of the Holy Dragon City, all the heroes of the Holy Dragon City are gathered here, the Holy Dragon City at this time, it is not a month ago, there are only two heroes, Jin Tao and Amy, at this time, the Holy Dragon City, after a month of killing skeletons, can be said to be full of talents, many creatures are lucky to be promoted to become elite units, but due to the difficulty of the battle when promoting to heroes, all of them appear randomly, so a large part of the elite creatures' promotion trials are declared unsuccessful, fortunately, Jin Tao through the heart link, Hints were given to the elite creatures of the trial, so there were no deaths of elite creatures.

Even in addition to the part that failed the trial, there are more than a dozen new heroes.

Among them, there are only three that Jin Tao likes the most, one is Thor who is promoted to a hero as an initial creature.

thor

Class: Hero

Ability:

Thunder Grid: (Enhanced by the Power of Thunder) Casts a lightning net attack covering a radius of 20 meters, cast times: 50, and regenerates 5 casts per minute.

Damage Enhancement: (Newly Acquired by Promotion) Attack damage doubled.

The other is Lan Qi, the hero of the Holy Dragon's promotion.

Lanqi

Class: Hero

Ability:

Ice Elemental Guardian: Gain the ability to summon the Ice Elemental, which can summon ten units of Ice Elemental Guardian per day.

The last one is the Hero Demon Spirit, who has been promoted by a magic mage.

Demon Spirits

Class: Hero

Ability:

Archmage Guard: Gain the ability to summon an archmage, and be able to summon five units of the archmage as a guard every day.

After the former was promoted to a hero, the original lightning attack was strengthened, and a hero ability that doubled the damage was obtained, making it a veritable firepower player.

As for the latter two, Lan Qi himself is a tenth-order creature, and the ice element guard ability obtained by the promoted hero is even more perverted, it is simply a super version of the ice element recruitment point, and the same is true for the demon spirit, the only difference is the rank and number of troops summoned, and the two work together, it is easy to pull up a ranged army.

As for the other new heroes, it's not that it's bad, but compared to Thor, Lan Qi and Demon Spirit, it's a little inadequate.

"Master, what are we going to do next? Have you been waiting in the castle? It was Amy who spoke, as a veteran who had been following Jin Tao's side, and undoubtedly had advantages that those new heroes did not have.

"I haven't thought about this question yet, after all, the appearance of those high-level undead creatures is something we didn't expect before" Speaking of this, Jin Tao paused for a moment, "But if this situation continues, we may not have the strength to compete with it in a short period of time."

Although Jin Tao did not answer Amy's question clearly, listening to the meaning of his words, it was clear that he affirmed Amy's words.

"Master, since we have no way to fight those undead now, and there is no way to attract enough undead to the city of Canon, I think we should find more forces to share the pressure for us, such as the other side of this mountain, I think there should be the forces we need."

"Mistress Amy, do you mean to open a passage to the other side of the mountain, and then let the undead go through the passage to the other side of the mountain?" Without waiting for Jin Tao to say it, Thor couldn't wait to take Amy's words.

"This is not a bad way" Jin Tao thought about it for a while, and felt that this was the only way at the moment.

In the following month, Jin Tao opened a passage through the entire mountain peak from the middle of the mountain, and personally attracted the flying troops among the undead creatures, so that they could find the location of the mountain peak passage.
