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

"If your core structure is damaged before the time runs out, but you still manage to kill all the monsters, your upgrade will be invalid. You will need to pay again to upgrade, and the cost will not be refunded."

"If you fail to kill all the monsters and the core building is destroyed, you will be eliminated and lose everything."

The AI ​​from Heavenly Path was particularly verbose this time, and it seemed that this wave of monster sieges to improve quality was indeed difficult. However, Yang Fei had already made up his mind, so there was nothing to hesitate about. What was meant to come would come eventually.

"Respected Apprentice Lord Yang Fei-1, your Novice Trial Core Building Upgrade Challenge will begin in twenty minutes. You will be facing an unprecedented wave of monster siege. Monster type: Slime, Monster level: Beast Level 0, Monster quantity: 56666."

"Attention! In this monster siege, to successfully upgrade your core building, you must defeat all monsters within three hours and ensure the core building you are upgrading remains undamaged. Failure to do so will have serious consequences!"

"Please adjust the position of the War Slab... The movement and reconstruction functions will be restarted after the siege ends." As the final announcement fell, the gray light of the core thatched hut in the center of the Sky Island flashed, and all the buildings on the entire Sky Island trembled in unison.

Yang Fei had a feeling that all the auxiliary buildings seemed to have welcomed their center and their longing at that moment. It was a sense of instinctive submission from the depths of their souls. It was no wonder that it was the core building bestowed by the Sky Island world. Being able to connect with the lord's mind was just different.

Then, a countdown appeared above the core building: three hours and twenty minutes. The moment the countdown began, the war corridor and war slabs all rose up uncontrollably, and the familiar blue doors slowly emerged.

"Huh? Is this still the same monster-farming method? Slimes, level 0 beasts, nothing changed, so the monster spawn rate should be the same too. Nearly 6 monsters seem exaggerated, but it's useless!"

The moment the familiar blue door appeared, Yang Fei finally relaxed. As long as the monster-killing method remained unchanged, it wouldn't matter how many came, because under normal circumstances, once the number of Sky Island defense towers increased, your monster-killing efficiency would no longer be as good as my killing efficiency.

Even now, so what if the attributes are quadrupled? The chain reaction caused by the succubus killing the Ice Slime may not have the exaggerated destructive power as before, but that doesn't mean the entire Sky Island has enough defensive towers now!

For this defense, Yang Fei arranged for the first line of defense to be a gray arrow tower used by the succubus girl. Yang Fei gave her 60 gray crystals and told her not to be stingy and to use them as she pleased.

Although she only needs to kill the Ice Slime and the Mimic this time, in certain situations, the Succubus's unfathomable strength is still an important trump card for Yang Fei. If a difficult enemy appears, he may still have to rely on her. So, he can do without any of the other energy crystals, but he cannot do without hers!

The second line of defense is still Youyi's flamethrower tower. It is mainly responsible for dealing with the acid and corrosive slimes that were not killed by the exploding ice slimes. It is the first line of defense. Yang Fei also gave him 10 gray crystals, telling him to go all out and not to be deliberately stingy.

The third line of defense is the white arrow tower group where Yang Fei is located. This time, these arrow tower groups are responsible for dealing with the elite slimes that pass through the first two lines of defense without taking damage. When the defense is tense, their health should be reduced to below the level that can be killed by the flamethrower towers. This is the main target of the arrow tower group. Of course, if there is no tension, then go ahead and kill them!

The weakened monsters from the arrow tower group will be handed over to the two fire-breathing towers and one slowing tower located next to the black mud swamp. This time, Yang Fei let Yue Lingling take control of the new fire-breathing tower to assist the previous two inferior demon combinations.

Li Han and his duo were in charge of a newly recharged gray arrow tower. Their main objective was to eliminate special targets that got too close to the flamethrower tower and the slow tower, and to protect the three defensive towers on the third line of defense.

After the slimes pass through the three lines of defense, Yang Fei's white arrow towers will then be responsible for dealing with the remaining slimes. This explains why the arrow towers on the second line of defense sometimes faced considerable pressure; how could they not be stressed when they had to do two jobs?

Secondly, Yang Fei, as the lord, is also under great pressure this time. He needs to replenish the energy of all the white arrow towers in a timely manner, which may prevent him from paying too much attention to the battlefield. However, as long as he follows the plan he set beforehand, there shouldn't be any major problems.

Because Yang Fei needed to replenish the energy of the arrow towers, all the remaining gray crystals, except for the three he gave to Yue Lingling and the two inferior demons, were in his hands so that he could replenish the arrow towers at any time.

As for leaving some as a backup, that's not an option this time. With nearly 6, we have to go all out. At this point, it would be really unnecessary to risk failing to advance just to save relatively unimportant energy crystals.

As for the seven tentacle jellyfish, they need to be positioned in the back this time. They will stand in front of the city wall along with all the remaining inferior demons. After Yang Fei's arrow towers have dealt with the elite slimes first, they will promptly fill the ground blocking positions and do their best to prevent the ordinary slimes from advancing. After the pressure on the frontal battlefield has decreased, these slimes will be left for the arrow towers to kill.

After arranging everything, Yang Fei stood on the gray ice arrow tower, looked at the blue door, and ended the countdown. All the arrangements had been planned in advance, so there was no need for Yang Fei to make any further adjustments. He just hoped that no unexpected situations would arise.

Slime: Beast Level 0, HP 320, Attack 16, Defense 0, Magic Resistance 0. A magical life form from another dimension, with no special abilities. Although it is an extremely fragile monster, you still cannot defeat it with your physique.

As the ordinary slimes jumped out of the blue door one after another, Yang Fei checked their attributes and found that they had indeed increased fourfold, without any other bonuses. He finally breathed a sigh of relief.

"It's alright, it's alright. As for the quantity, it's acceptable. Even with a fourfold increase in attributes, the Ice Slime only has four HP, which is still within the range of the arrow tower's one-hit kill. It won't affect the final result."

At the same time, a familiar voice that put Yang Fei at ease rang out, and Yang Fei finally felt completely at ease.

"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 9797 regular slimes will be replaced with elite-quality corrosive slimes. 11111 regular slimes will be replaced with elite-quality acid slimes, and 10000 regular slimes will be replaced with elite-quality blasting slimes. Good luck!"
