At the beginning, Lin Han thought that this countdown would not start until all the enemies were killed or retreated, but now it seems that the difficulty of this task has increased, the sky and underwater, no matter where the enemy is, as long as they are all killed, it will trigger the next round of tasks, if their strength is unbalanced, it will lead to a very terrible situation, that is, the enemies on a certain battlefield will accumulate more and more! This is also the reason why Lin Han wants He Hao and his party to come over quickly, their arrival can bring them new vitality, not only in the sky battlefield, but also in the underwater battlefield!

"I'll go, what kind of defense is this? Wang Ba Shell Tactics? ”

He Hao and the others' fleet quickly appeared in Lin Han's field of vision, and the defensive formation built under the water was also seen by them, they were all taken aback when they saw this defensive formation for the first time, this huge spherical defensive formation felt like a king eight shells, especially those thorn-backed dragon turtles, this size was too huge, right?

"What kind of king eight shell tactics, you all be careful, this time the enemy is very strong!"

Hearing He Hao's words, the pig chasing the macho man replied angrily, indeed, at the beginning, those deep-sea mad sharks brought them a lot of losses, because of the particularity of predation, all the attacked units were directly rushed to dozens of meters away from the defense line, and the powerful power of the deep-sea evil sharks made them unable to stop it, if it weren't for Lin Han's decisive formation of this special defensive circle, maybe their troops would have been consumed alive by the group of deep-sea evil sharks.

"Is it really that scary?"

Hearing what the pig was chasing the macho man, He Hao was also stunned. At first, he thought it was a bit difficult, but now it seems. This task does not seem to be as simple as a little difficulty.

"Without further ado, it's not for you to chat. Hurry up and join the fight, get rid of the underwater enemies quickly, and if you don't hurry, wait until this wave and the next wave of enemies gather before you know what the real difficulty is. ”

Lin Han interrupted their chat very decisively, that's right, this group of guys continued to chat, and they would not understand what real trouble was until the second wave of enemies came, and this time the number of enemies was still about 50%. It doesn't seem like a lot, but with a Siren, a Siren, a unit that combines status and healing, it can be a lot of trouble for them to fight.

I have to say that He Hao's arrival made Lin Han and their side a lot easier, because Lin Han's emphasis was on danger, and this group of players brought all their troops, including all the Sea Clan troops, so that the underwater battle began to become easier, but Lin Han's side was not easy. Because less than a minute after the end of the underwater battle, the third wave of the enemy, came. At the same time as this third wave of enemies attacked, Lin Han's mission on their side also changed. What started out as an exploration of the Siren Temple has now turned into killing all the Siren troops and waiting to enter the Siren Temple.

The name of the mission changed to let them know. This is the last wave of attacks. Since it was the last wave of attacks, the number of enemies this time was naturally extremely terrifying. Lin Han's minimap was already covered with red points of light, and enemies in the air and water had appeared. In terms of the number of enemies, there are more than 30,000 enemies so far!

"I think I can level up after this mission."

The pig chasing macho man looked at the numbers on the stat and didn't know what to say, more than 30,000 enemies This is just the beginning, because the number of enemies is still increasing, and the first batch of enemies is already approaching. It's not just the sirens who appear this time, because of the reason why Sky City joined the battle before, the battle in the air ended very quickly, the biggest feature of siren creatures is charm, once this ability is removed, then their combat effectiveness is actually not very high, and the ability of undead creatures and machines to be naturally immune to charm makes them fall into a disadvantage the moment the battle begins, and this time, in response to the situation of Lin Han's troops, the siren army directly brought their helpers as soon as they came.

The first to enter the range of Sky City is a group of giant bats and pterosaurs with a number of more than 3000 units, this group of creatures is a relative of the sea pterosaur, of course, they are much stronger than the sea pterosaur, the sea pterosaur is a 7th-order class, and the giant batterosaur is a 9th-order class, the gap between the 2nd order brings a huge change in attributes, the attributes of the giant bat pterosaur are very special, this group type is 2 times the size of the sea pterosaur The positioning given by the big guy system is not an output of troops, but a defensive class!

"The Iron Pterodactyl can finally be upgraded."

This was Lin Han's first thought after seeing the attributes of the giant bat pterosaur, the initial positioning of this guy Lin Han gave him was the type of law, curse and field control, and after this guy's terrifying transformation talent ability was displayed, he was summarized by Lin Han in logistics.

He didn't know exactly what the natural skills of lich heroes were, as not many players had ever obtained them in previous lives, let alone this special frost dragon lich.

However, one thing is certain, that is, the Lich's innate skill system is definitely very different from ordinary undead heroes, because at level 20 of Aniah, the late-stage development route chosen is not the attack and defense route chosen by ordinary French heroes, but the curse and transformation route. This guy's route was not decided by Lin Han, but he chose it himself, but with his hobby, the curse route was ruled out at the first time, the lich is a natural curse master, if he chooses the curse route, then basically in the middle and late stages, Anya will become a terrifying battlefield control hero, but this guy doesn't seem to have such a grand wish, at the same time that the talent was chosen, Lin Han just saw this prompt, and Anya had already chosen the transformation route.

After the transformation route is selected, some very peculiar skills will emerge from this guy's subsequent skill extraction, such as a transformation mutation drawn before, this skill is a very special skill, and there will be a 15% chance of transformation mutation when Anya is transformed, and some special mutation transformation classes will be produced.

This mutant class has appeared once, but that time it made Lin Han cry and laugh, because Anya made a cyclops, and in this production there was a mutation, the enhanced attribute obtained by the mutation is defense, and the weakened attribute is attack distance, so a melee version of the cyclops with an attack distance of only 4 meters but a basic defense of 210 points and a health value of up to 32,000 is created.

This mutation made Lin Han cry and laugh a little, but it also gave him a lot of inspiration, although this kind of cyclops has no long-range attack ability, but the super high defense plus health value makes them have extremely high survivability in urban warfare, and they also have the ability to attack the city wall and automatically convert it into siege damage, and at the same time increase a certain amount of damage, which is equivalent to saying that it has changed from a long-range archer unit at the beginning to a current melee siege unit.

This creature did not participate in the battle after the most slugging, but waited for the accumulation of the number in the sky city, and the mutation will definitely appear, and at the same time, Lin Han also checked the transformation mutation skill of the guy Anya, similarly, this skill can be upgraded, so far it is still primary, there is a 15% chance of mutation, and there will definitely be a higher chance of mutation after upgrading, as long as there is enough mutation chance, Lin Han is not worried about the problem of insufficient number of this class.

"Giant Bat Pterodactyl: Sea Clan Tier 9 Enhancement Class, this huge Sea Pterodactyl is extremely large, they are a very fierce unit, any creature that dares to approach their territory will be attacked by them, the corrosive acid sprayed by this group of creatures is very corrosive to armor, if it is hit many times, it may be fatal.

2. Corrosive Acid Mist [The Giant Bat Pterodactyl spews out a corrosive poisonous mist, enveloping all units within a range of 8x7 meters, and the units in the poisonous mist will receive 80 points of earth-based magic damage per second, while reducing defense by 5 points every 3 seconds, stacking up to 3 layers, and cannot be stacked with Acid Hunter.

The skills of the guys of the giant bat pterosaur are all buff skills, of course, they are all debuffs, 2 defense reduction skills, one that increases damage, and comes with the ability to kill low-level troops, which is a bit shameless, at the same time, the basic defense of this product itself is as high as 170 points, and Lin Han who saw it was also dumbfounded, the basic defense of this product is too high, right?
