"What kind of attack is this!"

Looking at the damage caused by the Sky Destroyer this time, the players of the entire Heaven were about to look stupid, none of the players successfully escaped from this attack, even the 9th order troops who were blessed with a messy buff state were also like this, just as a few units of the black dragon were devoured in an instant, there was no chance of resistance at all, this kind of attack was obviously not what they could withstand now.

"This group of idiots, the dragon blood crystal represents the power of the dragon god, thinking that it can be blocked with a few black dragons? It's too simple. ”

Rivigaz said very disdainfully, if you want to talk about the power of the black dragon, the black dragon's magic immunity ability still belongs to the power of the dragon god, they belong to the secondary dragon clan, and the slave created by the dragon god, the power of the slave and the master, which is more powerful is not comparable.

The loss of a large number of troops is a big blow to the players in heaven, of course, the bigger blow is morale, a large number of troops were killed in an instant, not to mention ordinary players, even elite players have left a lot of shadows in their hearts, the enemy has such a weapon, this is a great hidden danger for them, maybe something, this cannon fell directly on their heads.

"How long does it take for the Sky Destroyer to attack each time?"

On the Sky City, Lin Han was also asking about the use interval of the Sky Destroyer, to be honest, this time the Sky Destroyer attack was not as bad as the last time, the last Sky Destroyer attack not only drained the Sky City's defensive energy, but also drained the movement energy, and Lin Han couldn't rely on burning gold coins to control the Sky City to leave.

But this time it seems to be much better than the last one. After this attack, Lin Han looked at the energy of Sky City. Although it is not much, it can barely support the opening of the defensive shield of the castle in the sky. Of course, it is estimated that it will be shattered after a few attacks, after all, the energy is running out.

"It's almost 4 hours, that's why you put three dragon blood crystals, if the dragon blood crystals are reduced to 2, you can still maintain the attack, but the power will be reduced a little, and the cooldown time will be increased to about 6 hours."

Rivigaz analyzed it and said with certainty that this weapon was designed by him. And because of the second improvement, he had a new understanding of the ability of the entire Sky Destroyer, so he could give Lin Han such an answer.

"Something to do with the Dragon's Blood Crystal? What if I put more Dragon's Blood Crystals? ”

Hearing Rivigaz's analysis, Lin Han understood something, obviously the role of the dragon blood crystal in the Sky Destroyer is not ordinary, the previous effect Lin Han also saw, with the effect of the dragon blood crystal, the Sky Destroyer's attack seems to be accompanied by a powerful ignoring magic resistance effect, and at the same time with two dragon blood crystal attribute effects. It's not a little bit stronger.

"Never!"

Hearing Lin Han say this, Rivigaz immediately panicked, seeing that Lin Han was a little puzzled, he quickly explained: "The Sky Destroyer is actually not a real perfect weapon yet. In fact, too much energy can make this weapon unstable, and I've tried and analyzed it before. The maximum amount of energy this weapon can take is 3 dragon blood crystals, if there are more than three."

Said here. Rivigaz paused, his face turning ugly. Then he continued in a low tone: "I flipped through the history books of the goblin clan and found that there were goblins who used dragon blood crystals to make weapons a long time ago, but they underestimated the amount of power in the crystals, and used too many dragon blood crystals at one time, resulting in elemental chaos and confrontation, and the failure of that experiment directly evaporated a goblin city with a scale of 100,000, and since then, the goblin clan has never used dragon blood crystals for experiments. ”

Rivigaz's voice didn't sound like a joke, it also made Lin Han break out in a cold sweat, a goblin city with a scale of 100,000, what kind of concept is this? It can be said that the underground city that Lin Han entered before is actually not too small in scale, and there are thousands of goblins living in it, and this city of more than 100,000 is estimated to be not much smaller than Dragon City, or even huge.

In this way, the goblin city of more than 100,000 people was evaporated, which is a bit scary, although I don't know what role the dragon blood crystal played in that disaster, but from the tone of Rivigazi, these things must be the culprit, which is why Rivigaz was so flustered when he heard Lin Han say that he used more dragon blood crystals, it was not that there were too many dragon blood crystals to be useless, but that the goblin's current technique could not be controlled at all!

"In that case, 3 dragon blood crystals is the limit?"

Got this news, Lin Han was not very satisfied, although the 3 dragon blood crystals can also play a good effect, but obviously its effect will definitely not make Lin Han satisfied, the interval between the use of this weapon is too long, if the range and power are no longer larger, in fact, it is useless, no matter how high the damage is, it can only be said to be a killer in battle, and it cannot really dominate the left and right of the battlefield.

"It's not just 3 dragon blood crystals, in fact, the lord you are doing this time is also very risky, if you use 2 scarlet fireworks and a dream drop, it is likely that it will explode at the beginning. The power of the Dream Drop is relatively soft, neutralizing the violence of the Scarlet Fireworks, if their ratio is changed, this time it is not possible to attack yet, and it will solve us first. ”

Speaking of this problem, Rivigaz also had palpitations, and at the beginning he was still frightened by Lin Han. It is not impossible to use the dragon blood crystal with mixed attributes as a driving force, but it is very important to maintain balance, the balance between attributes is related to the stability of energy, the stronger the energy of the Sky Destroyer, the more stability is needed, otherwise once there is a little change, this weapon will kill Lin Han and them first.

"Hey, I can't use this thing often in the future!"

Rivigaz's words also made Lin Han startled, the Sky Destroyer with the Dragon Blood Crystal is actually very powerful, but the range has shrunk a lot, which is also where Lin Han is dissatisfied, if the range can be expanded, then this weapon is really powerful.

Of course, once it explodes, Lin Han will not suspect that the entire Sky City will become the damage range of the explosion, and at that time, it is estimated that without the enemy, the troops on his side will be almost lost.

At this time, the sky city is different from the original sky city, because of the complete spread of the corrupt earth and the increase of undead buildings, the current sky city is more like a moving country of the dead, countless undead buildings have turned the entire sky city into the world of death, and at the same time, the dense walls of white bones alternate with each other, combining three lines of defense, each wall of white bones is a strengthened corpse witch tower shining with dark green light, this is Lin Han's defense line, of course, there is also the void thunder hidden in the sky, However, this thing is rarely used by Lin Han.

Lin Han is now already thinking about further strengthening the defense tower, and it is not impossible to further upgrade the defense tower, in fact, there are two choices in front of Lin Han now, the first is to collect more advanced blueprints, which is an unattainable thing, because the high-level drawings themselves are few, not to mention the high-level blueprints of the enhanced and upgraded version of the tower of the corpse witch of the undead clan.

Another way is the guild, upgrade the guild center, after the guild center level 3, the player has several special rights, in addition to the guild level 2 point system, there is also the guild technology system, which is now a thing that many guilds are getting around, the technology system upgrade is not only for individuals, this is a way to improve the strength of all guild players, among which in the defense of the technology, high-level defense technology has a special technology choice - high-level defense tower.

This is something that requires a lot of resources to appear, you can upgrade the defense tower once, whether it is high-level or low-level, even the hidden defense tower is the same, of course, if it is a top-level defense tower itself, it is impossible to use this ability, as long as Lin Han can upgrade the technology tree to this point, he can upgrade the tower of the strengthened corpse witch again, this time he already knows the way, it is the tower of the lich, and the defense tower at this time is not just a defense prop, It is also an extremely powerful amplification item, the Lich Tower has the ability to cast spells, not only can it cause great area damage to the enemy in battle, but also the random triggering of curses and damage magic, and most importantly, players who have the existence of the Lich Tower, all corpse witches will have a certain chance of progressing to mutate into a lich after being promoted to level 3.

But this probability is very low, and it's random in the battle, it's not so easy to get the lich, the lich has a very high status in the cemetery clan, and it belongs to the existence of the 10th order of troops, although it is much lower than the level of the night dragon or something, but because of its low difficulty of obtaining, before Lin Han was reborn, it has become the pursuit of many players.

Lin Han's target is these guys, the lich is a mutated upgrade of the corpse witch, the level of 10 can already show their strength, if there are 4-5 units of the lich on the battlefield, the whole battle will become extremely simple and easy. (To be continued......)
