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

"Let the eyes of this floating island be at ease, and don't let those demons find any fault with us." Seeing that the defensive tower that released tentacles no longer made any moves, Sun Xiaoyu picked up his binoculars again and looked at the distant battlefield.

"Yes, platoon leader."

With the imposing entrance of the Ice Slime Lord, who had not yet issued any commands, the entire War Corridor's slimes froze, completely unresponsive to the attacks from the defensive towers, standing motionless as if mourning their lord and quietly awaiting their own demise.

Yang Fei was shocked to see how easily the Tentacle Tower had dealt with the seemingly powerful Slime Lord. He was so stunned that he couldn't even hear the kill notification and reward notification from the Heavenly Dao AI.

Once Yang Fei came to his senses, he immediately calmed down. He was still defending the city, and being overwhelmed by shock was not in his nature. He quickly adjusted his mood and began to take control of the battlefield situation again.

Yang Fei first ordered that the slimes standing in the corner be ignored. He understood that these slimes were not actually mourning for their lord, but were affected by the attack aura emanating from the tentacle tower, which directly shattered their intelligence.

Although they still have health, they're practically dead. There's no need to deal with them anymore. For now, focus on dealing with the new slimes constantly spawning from the blue portal. We can deal with these slimes that have become experience points later.

Secondly, Yang Fei had already seen the newly spawned slimes from the Blue Gate moving normally towards the War Corridor. They ignored their completely still brethren and went straight onto the War Corridor, heading towards the core of the Sky Island. These newly spawned slimes were not affected by the high-level aura of the Tentacle Tower and were still jumping around happily, so these newly spawned slimes had to be dealt with first.

The ensuing battle unfolded perfectly as Yang Fei had planned. The sheer number of Ice Slimes meant there was no need to consciously control their positions. The battlefield became the Succubus's playground, and the damage inflicted by the other defensive towers was negligible.

Especially with this wave of monsters numbering nearly 60,000, and with the leader, the Ice Lord, dead, the slimes were left without command, and their formation was already somewhat chaotic. They were no longer hopping out one by one through the blue gate.

Instead, they were constantly pushed out by their compatriots behind them. The refresh rate of the blue door was almost reaching the limit of the first three waves of monsters in the novice assessment, estimated to be close to 600 per minute.

With such a dense lineup, coupled with nearly one-sixth of them being traitors—the Ice Slime—the Succubus's monster-killing efficiency is already more outrageous than the combined monster-killing efficiency of all the defensive towers.

If it weren't for the goal of maximizing kill efficiency with minimal energy, Mona could have simply blocked the blue gate and farmed, preventing the other turrets from getting a single kill. Plus, even if Mona couldn't gain experience from the friendly units affected by the Ice Slime's self-destruction, she could still farm there.

The Ice Slime she directly killed already provided plenty of experience; there's no need to waste that experience by blocking the gate unnecessarily. It's better for everyone to get a few kills and absorb some experience.

With another prompt from the Heavenly Dao AI, five white treasure chest monsters and ten gray treasure chest monsters were each hit by an arrow from the succubus girl, and this long defense finally came to an end.

"Respected Lord Yang Fei-1, congratulations on your perfect defense against this powerful monster siege! You have killed 16426 ordinary slimes, 40240 elite slimes, one lord slime, two white mimics, and ten gray mimics. The total time taken was one hour and twenty-one minutes. Congratulations, your defense is successful!"

"Dear Lord Yang Fei-1, because your core building, soldiers, and citizens suffered no damage, and the defensive towers and walls were also undamaged during this core building upgrade challenge, and you ended the monster siege ahead of schedule, achieving a no-damage clear, your core building upgrade is successful! The ultimate core thatched hut has been upgraded to a gray-quality initial wooden hut!"

After the defense was over, Yang Fei, somewhat exhausted, led everyone back to the expanded sky island. After everyone rested on the city wall, Yang Fei collected all the spoils and, with Mona, eagerly returned to the core building.

At this point, the original dilapidated thatched hut had disappeared and been replaced by a small wooden cabin with sharp edges and corners. The somewhat cramped one-bedroom and one-living room cabin had been transformed into a slightly more spacious one-bedroom, one-living room and one-bathroom cabin, with functions that were nearly complete. It was no longer a thatched hut with nothing inside.

Core Cabin (Gray Initial): Resilience 2000, Defense 20, Spell Resistance 20. It is the core building of the Sky Island. If it is breached, the defense is considered lost, the lord loses the Sky Island, and returns to his own world.

Core Cabin (Upgradeable): Costs 100 silver coins and 100 gray magic cores. Upgrades one auxiliary building to level 5 (gray initial quality), two resource auxiliary buildings to level 3 (colorless advanced quality), and requires 20 territory residents and 10 soldiers to upgrade the core cabin from initial to intermediate level.

After upgrading to the intermediate level of the core cabin, the concentration of spiritual energy in the surrounding environment will increase slightly, and the area of ​​the sky island will also increase to a radius of 1+2+1 kilometers (the first 1 is the initial cabin sky island area, 2 is the expansion area of ​​the intermediate cabin, and the last 1 is the additional expansion area).

Core Cabin (Special): The Core Cabin is highly bound to the Lord. All of the Lord's permissions are related to this core. Currently unlocked are the system data panel, system warehouse, Heavenly Path Shop level 5, and the Lord's exclusive abilities - move, adjust, and one-click collect.

The Lord's ability to transport people has been unlocked, allowing you to lead one hundred non-Sky Island residents to and from Sky Islands. Simultaneously, the system warehouse has been expanded to 100 slots, and the stacking capacity has increased from 1000 to 2000. The Heavenly Path Shop has unlocked some additional items beyond the basic rewards. (The Defense Tower Shop has unlocked gray and white quality horizontal-firing turrets.)

Note that with this Sky Island upgrade, your War Corridor has changed from a five-meter-wide dirt path to an eight-meter-wide gravel path (gray grade), which can withstand stronger attacks.

Note that the core building is already at gray quality. Upgrading it three more times will trigger another upgrade challenge. Some auxiliary buildings will be restricted from upgrading due to this. Please pay attention to upgrading the quality of auxiliary buildings in order to upgrade the quality of the core building.

Note that because you have upgraded to a gray-quality core cabin, the spiritual energy density around the Sky Island has increased, and your white arrow towers can now recover in half an hour. After upgrading to a white-quality core building, white arrow towers can be replenished continuously during battle.
