All-out Tower Defense: My Card-Drawing Talent is a Bit Strange

It should be noted that Yang Fei's initial sky island is already a circle with a radius of 50 meters. Roughly calculated, the edge of Yang Fei's sky island is now more than 300 meters long. To completely enclose it would require extending about 30 square meters, which is completely impossible at this stage.

"Hopefully, the basic rule that 'random monster sieges will not occur' will not be changed during the beginner trial period. Otherwise, we will not only have to adjust the defensive towers, but also the positions of the city walls, which will be quite overwhelming."

Yang Fei stood on a city wall, looking at the endless night sky outside the sky island, and then at the few defense towers behind him. He felt a little safe. Having grown up on a planet with a population of two trillion, he knew that overcrowding was common knowledge. Now, suddenly being in such a vast and empty place, he felt somewhat uncomfortable.

Moreover, with the walls providing a barrier, this location is relatively safe. It's not like before, where without the defensive towers, the entire sky island was practically defenseless. Now, even if monsters manage to break through the defensive towers' firepower, they'll be stopped by the walls.

"With this wall, I might actually be able to try the difficult wave before the end of today. Every daily challenge opportunity is precious, and the higher the efficiency of accumulating resources, the better. There's no need to beat around the bush for two gray crystals."

After much deliberation, Yang Fei finally made up his mind before the two white arrow towers were fully charged.

At the same time, this is also the confidence that comes from feeling a sense of security while standing on the towering city wall.

Once the two white arrow towers were fully charged, Yang Fei checked the time and it was exactly 10 p.m. Without further hesitation, he led the two tentacle jellyfish to the front of the defensive towers and started the difficult challenge.

"Apprentice Lord Yang Fei-1, your first wave of the beginner trial, a difficult monster siege, will begin in ten minutes. Monster type: Slime, Monster level: Beast, Level 0, Monster quantity: 236."

"Please adjust the position of the War Slab and place the defensive towers you wish to use. Please note: If a defensive tower placed on a War Slab is destroyed by monsters, it can be rebuilt after the monster siege is over for a small amount of currency. Towers in other positions cannot be rebuilt."

"Please also note: During the monster siege, the building and tile movement functions in the core thatched hut are temporarily disabled, and the defensive towers on both sides of the War Corridor cannot be moved. The movement and reconstruction functions will be restarted after the siege ends."

The familiar voice rang out again, and the blue gate and the war corridor reappeared. As usual, Yang Fei placed the two white arrow towers in the middle, but this time the gray arrow tower he personally controlled was not in the rear.

He moved the gray arrow tower as close as possible to the two white arrow towers. This time, he couldn't slack off; he had to go all out. There were 236 monsters; the two white arrow towers could kill 200, leaving 36 monsters.

The two tentacle jellyfish can also kill enemies, but their attack power is too low to effectively kill enemies in a short time. Their main job is still to stay in front of the arrow towers and hinder the enemy's advance. Therefore, they must ensure their output to reduce the pressure on the two arrow towers.

Once the two tentacle jellyfish excitedly reached their designated positions, Yang Fei immediately ended the countdown on the blue gate and initiated the first wave of difficult-difficulty monster siege.

The blue door opened, and the familiar slimes bounced out. Yang Fei glanced at their attributes, which were exactly the same as the previous two waves, and breathed a sigh of relief. It seemed that the change of the four basic difficulty levels was indeed just an increase in quantity.

"Ding~, Your Excellency Apprentice Lord, you have displayed great bravery in protecting the Sky Island and defending against the Slime Clan's attack. The Slime Clan has developed a slight animosity towards you, triggering a special event—The Gaze of the Slime King."

"The next 30 regular slimes will be replaced with elite-quality corrosive slimes. The next 12 regular slimes will be replaced with elite-quality acid slimes. Good luck!"

Before Yang Fei could even aim at the first slime, the familiar voice rang out again. This time, it wasn't replacing the last slime, but starting directly. It seemed like a mixed formation, which was a bit troublesome.

Yang Fei quickly fired an arrow, killing the targeted slime. Then, while drawing his ballista, he looked towards the blue door. Sure enough, among the constantly emerging slimes, the Corrupted Slime, which had originally appeared last, had already mixed in with the ordinary slimes.

At the same time, Yang Fei also saw a slime the size of a washbasin, but with a darker green color, hopping out.

"Acid Slime: Beast Level 0, Elite Unit, HP 70, Attack 20, Defense 0, Mutant Corrosive Slime. Its body contains a weak acidic corrosive ability and can release an acid water gun with an attack range of three meters, enabling ranged attacks."

"Injecting this acid water gun will cause double the damage to buildings, and also has a corrosive effect that lasts for half an hour. It will have a continuous impact on the land and farmland of the floating island, which will need a certain amount of time to decompose naturally, or it will require the use of special items or special skills to eliminate it."

"Holy crap, this thing can attack from a distance." Although Yang Fei knew that some slimes could spit poison, he really didn't expect that this thing would appear at the weakest level, level 0 of the beasts.

Even so, Yang Fei's hands moved quickly. He aimed at the acid slime and fired an arrow, instantly killing it. Only a gray card was left on the spot. However, Yang Fei didn't have time to care what it was. He continued to draw his bow and arrow, and before the acid slime could reappear, he aimed at the next ordinary slime and continued to attack.

Although these guys look pretty strong, being a mutated variety of Corrupted Slime, as long as they're still at the Beast level, the gray and white arrow towers can still deal damage. What's more, even though your attack has increased and you have ranged attack capabilities, your health is still within the arrow tower's one-hit range. As long as you can't get out of the attack range, all ranged firepower is useless.

While firing, Yang Fei quickly adjusted his tactics. The priority for the two white arrow towers remained the same: corrosive slimes, then regular slimes. As for the acid slimes, there were a total of 6, and as long as they didn't all come out at once, he would take care of them.

At the same time, he ordered the two tentacle jellyfish to temporarily retreat to the latter half of the war corridor to create space for himself to kill the acid slime. Although these monsters usually only attack the core, this is only a general situation, and no one can guarantee that other situations will not occur.

The reason I stopped the two tentacle jellyfish from interfering with the corrosive slime was because their attacks are different from the direct impact of ordinary slimes, making them more difficult to recover from. Now that the acid slime not only has a higher attack power but also comes with a continuous effect, we need to be even more careful.

These two subordinates of mine are the core of the unorthodox defense, and they absolutely cannot be harmed. Even if the city wall loses blood, they should not be seriously injured, otherwise my subsequent plans will be greatly restricted.
