Guffy's meaning is quite obvious.

All the way to the siege of the city, all the attacks have to face one choice - the city wall.

You can't break through the opponent's walls, and you can't break through the opponent's defenses. Therefore, in the future, the Scourge Legion will face the traps and defenses set by the other party...... No matter how many troops there are, they will be consumed alive like this.

As an attacker, the Scourge has too many flaws.

You can't use siege equipment or other magic items as easily as the Lost City. After all, this time he wants to forcibly attack the main plane, and the enemies he has to face are the six billion players of the "plane" and tens of billions of NPCs.

I don't want to do it any other way.

"I see what you mean!" Oxtin nodded. "Indeed, in a situation like ours, all the creatures that appear except for the Scourge are enemies. The troubles and difficulties we face are not ordinary, so if we want to attack the enemy better, we must also think of a little way. ”

"What's the solution?" Gao Fei looked at Oxtin. "What's your idea?"

"Air Force!"

Oxding paused for a moment and said these two words slowly.

"We can currently choose the air force and use airdrops to directly evade the defenses of these cities."

"In that case, we can be directly inside the city and make all their defenses useless to us."

Gao Fei nodded.

To be honest, he thought it was a good suggestion. It's just a little unrealistic......

Why?

In the Air Force, there are many beasts that can be ridden. Hippogriffs, dragon eagles, griffins, gargoyles...... But in this case, it is obviously unrealistic to want to tame these beasts or flying monsters one by one. Because the number of the Scourge Legion is so large, it is impossible to rely on flying monsters to carry them.

Because a thousand, ten thousand flying demonic beasts can't play a big role at all.

Because the number of skeletons that can be carried is not very large, even if it takes the opportunity to fly to the center of the city. The number of people is not too much, it does not play a big role at all, and it does not reach the role of flowering in the middle. It can only act as a pull, and it is very likely that it will not even be able to reach the involvement.

"How's the goblin airship?" Oxin pondered for a moment, thought about it and said. "The space of the goblin airship is quite large, and it can carry at least more than ten thousand skeletons at one time."

"It's a good choice." Gao Fei nodded. "But I haven't been on a goblin airship, can you tell me about it?"

Goblin airship.

This is the pinnacle of goblin technology, which only relies on oil and engines...... It's like an airplane with modern technology.

The space inside is huge, and it belongs to the means of transportation.

Goblin airships aren't safe, though.

After all, it's just a game, and the flying tools made by NPCs still have a lot of flaws, first of all, the flight speed is quite slow, only a line faster than riding a horse. But it's a lot faster than walking...... Of course, the rest of the story is security.

It is also the security issue that Gao Fei is most worried about.

After all, it is above the sky, and it can't go up to the world and the ground, if there is really a problem, then it will really be no way to go to the sky and no way to enter the ground. So you have to think about everything......

"Safety...... How so? Oxin hesitated. To be honest, the probability of an accident in flight is about 1 in 10. Because of the convenience, many people choose to take the goblin airship. ”

****！

Gao Fei was dumbfounded.

The probability of one in ten is too high, if it is one percent, you can still accept it. What does this mean, one out of every ten goblin airships is destined to fail to reach the location safely.

"No, the probability of safety is too low."

Gao Fei shook his head.

"I don't think about goblin airships. Although the flying units are quite good, the targets are too obvious. ”

"After this ploy is used once, the second time it doesn't work."

"You can only use this trick once, can you?"

Gao Fei asked rhetorically.

Oxin was silent for a moment, and only after a moment did he have to confirm Guffy's speculation.

In fact, this is the case.

If you want to carry out a surprise attack, to be honest, use the air force to break into the gaps in the opponent's defenses, which is naturally a good choice. But you must know that there is more than one city in "Plane". In addition to the Ironforge Fortress, which has been completely turned into a plague land, and the lost city that has been invaded, there are one hundred and thirty-four fortresses in the plane.

After using such a strategy once, it cannot be used a second time.

Whether it's an airship, a horned eagle...... Again, if you want to actually perform an airdrop attack, it will take at least two months, or even three months, of preliminary preparation. But after all this work, there is only one chance to use it.

This is undoubtedly quite wasteful.

So Gao Fei plans to find a strategy similar to a panacea, which will never tire of use. Naturally, the air force has no way to take this place, and even after it appears once, in the fortress it faces in the future, whether it is a player or an NPC, there will be an air defense.

"Is there any other way?" Gao Fei asked.

"Except for the Air Force, other ways ......"

"This method is good, but it can only be used once, not continuously."

"If you think about it, is there any other way?"

"How's it going?" Oxding paused, and came up with another bad idea. "We have enough skeletons, and there's no need to fight these guys head-on. If we want, we can choose to dig a passage out of the ground and slowly dive in, what do you think of this method? ”

Gao Fei didn't bother to speak anymore.

The idea was a complete spoiler, to be honest - Guffy had had the idea for a long time, but almost immediately, he swept it out of his mind.

Because it is even more impractical than using the Air Force.

The reason why there are so many changes and dangers in the Air Force is because of the ever-present Gangfeng, as well as the various fierce monsters that occasionally fly down from high altitudes. Once encountered, the goblin airship will fall completely.

Of course, the so-called 'burrowing' is not very realistic.

The entire underground is not all complete, the entire underground is like an ant nest, if you dig directly, it is even very likely to break into an unknown dungeon. It's obviously not a good idea to get into a dungeon before you can settle the fortress you're facing.

So digging a passage out of the ground doesn't actually work at all.

"I'm talking about other methods." Guffy gestured. "Is there any other way we can directly circumvent these defenses. Like, like ...... Teleportation array. ”

Teleportation Array.

Yes, Gao Fei has always had such an idea.

If there is a teleportation array that can appear at any time and can be carried with you at any time. It only takes one or two people to sneak into a city and open these portals, so that they can directly avoid the opponent's various fortifications and hit the enemy's softest belly!

"Teleportation array, this is a good choice."

"It's just that it's not that easy to create these teleportation arrays."

Oxtin nodded.

"First of all, we need materials for a wide variety of precious metals."

"And then you need the technology to create a magic array."

"It's all technical, so we don't have anything to do."

Gao Fei froze.

Truth be told, it's really a bit of a problem. However, the most difficult technique and the seal carving of the magic array may not be necessary to worry about at all, after all, these things can be asked about the old tree. As the longest-surviving NPC in the entire "Plane", there won't be too many questions if all the knowledge asks him.

Maybe ask the Evil-Eyed Tyrant and he'll know, too.

"Well, when this battle is over, I think I need to go back to the City of Scourge." Gao Fei couldn't help but pinch his temple. "Hopefully this fight will end sooner."

But obviously.

Gao Fei's idea would be shattered, and the Lost City would be far stronger than he had imagined.

Rumble!

The battle continued, and boulder bombs slammed down from the sky and landed in the sparse sea of skeletons. Explosions began to sound one after another, and the glow of the fire almost dispersed the entire night.

"The frequency of boulder bomb drops has not decreased in the slightest."

"But their other resources don't seem to be enough......"

Two days and two nights.

Almost a million players are consumed, and no matter how long the supplies have been hoarded, there will be a little shortage. By the time the sun rose on the third day, the boulder bombs began to be thrown more and more slowly.

"Alright, they're finally starting to run out of support, and now it's our turn to attack!"

Gao Fei's eyes narrowed.

"Kill!"

In the midst of the cheers, the originally sparse sea of skeletons became dense again. Vast swaths of skeletons rushed frantically towards the entire Lost City.

At this time, the real war began.

The skeletons roared away like hungry wolves, desperately rushing towards the Lost City. Magic, flames, soaring into the sky, lit up almost the entire sky.

The vast ground and the silent shouting quietly played a prelude to the undead.

The Lost City is on its way to destruction.
