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

No matter how hard Yue Lingling and the other two tried, it was just a drop in the ocean. But Yang Fei had really done his best. He couldn't give more. Giving these five thousand unpredictable people a space to live was already a great act of mercy.

It should be noted that many of these people are carrying firearms. Although they cannot harm Yang Fei, who has already entered the martial arts realm, it is hard to guarantee that these people will not use their cleverness to cause trouble for him.

He had already done more than enough by allowing them to live here; whether they would starve to death was not his concern.

If he were a lord developing normally, he wouldn't want to contribute a single cent to the basic guarantee of 60 catties of white rice. As for taking half of the reward, that's even more impossible. This is my sky island, and everything I have comes from me. You're not even one of my subjects, so why should you take a share of the resources?

Although Yang Fei has a saintly heart, his priority right now is to develop the Sky Island's defense towers and challenge higher-difficulty monster sieges. He can't spare the energy to train these people or build relationships with these unrelated individuals.

Bringing them here was also for his own benefit. Yang Fei had to prioritize supplying Sky Island itself and his own people. As for the rest, he could deal with them later. He just hoped they wouldn't try to outsmart him, otherwise... A subtle cunning flashed in Yang Fei's eyes, a cunning that didn't belong to his sunny self.

"The company commander from that other world wants to have a chat with you." The succubus girl was noticeably more reserved today after last night's battle. Gone was her usual taunts and disdain; she was unusually serious, as if trying her best to play the role of a personal secretary. Her purpose was unclear.

"Let's talk about it after we complete the Sky Island Ascension Challenge." Yang Fei had already used his Lord privileges to check all the defense towers, and their energy was almost full. They couldn't waste any more precious time.

Today's goal is to clear the second wave of the 10x Extreme Mode. Including the daily challenge and the upcoming promotion challenge, I will face a total of 6 waves of monster sieges today. Each wave will probably take a lot of time, and I will be forced to rest for an hour after each wave. I really don't have time to chat right now.

"Core Thatched Hut (Upgradeable): For 1000 copper coins, the ultimate core thatched hut can be upgraded to the initial core cabin. The concentration of spiritual energy in the surrounding environment will increase slightly, and the floating island will also be upgraded to a radius of 1000+1000 meters."

Note that the core thatched hut has reached its level cap. The next upgrade will upgrade it to a gray-quality core log cabin, which will trigger a powerful monster siege. Successfully defending the hut will result in a successful upgrade; otherwise, it will be obsolete. Please choose carefully.

Note: If the upgrade is successful, the Sky Island environment will reach the most basic training environment in the Tower Defense world. The recovery time of the white quality defense tower can be shortened to half an hour. After upgrading to the white quality core building, the white quality defense tower will complete the cycle of firing in the corresponding environment and no longer need to replenish energy.

Note that the core building currently has no grade. Its grade will change during the next upgrade, and some auxiliary buildings will be affected and unable to be upgraded. Please pay attention to upgrading the grade of auxiliary buildings in order to upgrade the grade of the core building.

Because the next upgrade will be to gray quality, which is the most basic quality, the next upgrade will not be affected by the auxiliary buildings for the time being. However, the effect will gradually become apparent during the next upgrade.

Additionally, please note that upgrading the quality of core buildings will significantly increase the Sky Island's attractiveness to potential monsters in the surrounding environment, thereby increasing the probability of monster harassment and random monster sieges.

After confirming the upgrade materials and precautions for the core thatched hut once again, Yang Fei took a deep breath. According to the information in "Tower Defense World", upgrading the quality of the core building would indeed attract a wave of powerful monsters to attack the city.

This wave of powerful monsters is about 20 times more difficult than the current wave in extreme mode. However, in addition to having four times the original attributes, the number of monsters is also four times. Only by successfully defending against them can you advance.

Furthermore, during this quality upgrade process, monsters of higher levels may appear! A large number of elite monsters, and even boss monsters.

Yang Fei is now in the second wave. After the Sky Island defense has been greatly strengthened, the overall difficulty should not be too high. Moreover, there may be traitors among the monsters, such as the Ice Slime. In theory, I can defend it completely.

However, Yang Fei wasn't entirely confident of a 10% success rate, and he was also worried about the existence of the so-called random options. The Extreme Mode shouldn't increase the number of monsters, but it clearly did during the first large wave, and the final ten-times Extreme Mode monster count was approximately ten times that of the normal Extreme difficulty.

Even if one's own Skyblock upgrade is a factor, it doesn't change the final conclusion—"the current Extreme Mode will increase the number of monsters." Therefore, it's necessary to consider whether the current Skyblock upgrade rules still fall under the previous universal rules.

Moreover, achieving four times the monster's attributes is not an easy condition. A normal slime has 80 HP, and a corrosive slime has 90 HP. After quadrupling, it clearly exceeds the self-destruct kill of the Ice Slime, requiring additional output from the Flame Tower. Energy Crystals are likely to suffer a significant loss this time.

However, Yang Fei had previously accumulated 157 gray crystals, not only as a precaution but also for use in situations like this. Although he could try a single round in the 1x extreme mode to gauge the difficulty, some more aggressive strategies had to be tried to snowball the advantage and accumulate resources more effectively.

This is also part of testing a lord's decision-making ability. Hesitation may allow one to live longer, but on some key decisions, a lord must be aggressive.

Moreover, this kind of radicalism is not about going to one's death or making unprepared adventures. The sky island's defenses have been strengthened, and the ground blocking "army" composed of 7 tentacle jellyfish, coupled with the succubus girl's excellent combat power, Yang Fei still has some confidence.

"Come on, so what if you come in large numbers? Even if you exhaust all your energy crystals, the upgraded double limit mode should still give me more surprises. I'm sure I can earn even more."

Without much hesitation, Yang Fei led Mona, Yue Lingling, and other ground troops to the city wall and spent 1000 copper coins to upgrade his core thatched hut.

"Spend 1000 copper coins to upgrade the quality of the core thatched hut. Note that this upgrade will attract a powerful wave of monsters to attack the city!" The familiar AI prompt sounded at the right time, and Yang Fei directly selected yes.

"Understood, Trainee Lord Yang Fei-1, your core thatched hut will take three hours to upgrade to a gray-quality core cabin (initial). You are about to face a powerful wave of monsters that are far more difficult than the waves you are currently facing."

"Please note that if monsters rush into your territory and hit your cabin, your upgrade will be considered a failure. If you can kill all the monsters before the time runs out, the upgrade will be considered a success."
