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

But this increase in numbers was something Yang Fei hadn't expected. He might be facing a million-level monster siege at the very end of this wave, which seemed to be coming far too early.

It wasn't that he was afraid, but rather that he was severely lacking in charging slabs, and he would probably have to consume precious energy crystals again. Yang Fei disliked consuming such strategic resources.

The four basic currencies are: "Gold Coins, Magic Cores, Crystals, and Spirit Stones". Gold Coins and Magic Cores are basically currencies that need to be accumulated in the early stages, but accumulating too many is not very useful and it is better to convert them directly into Sky Island combat power.

Spirit stones are extremely important, not only as currency but also as a cultivation resource, even more so than gold and oil on Azure Star. No one wants to have too few spirit stones.

Only crystals, this basic currency that falls between the two functions, need to possess the crucial function of being both accumulated and readily available. Especially in special circumstances, crystals can be lifesavers, directly powering defensive towers or certain production buildings.

Moreover, crystals can be used directly in the face of emergencies, and since there is no usage process or cooldown time, their cheap acquisition makes them even more popular than spirit stones in terms of ease of use.

In terms of strategic positioning, energy crystals are a crucial resource that Yang Fei must stockpile. During simple monster sieges, Yang Fei prefers to endure the hardship himself rather than expend crystals, stemming from this obvious reason.

With a million slimes attacking the city, Yang Fei knew they might drop more crystals, but he really didn't want to use the crystals on them. These slimes weren't very cost-effective, and using crystals to replenish the energy of the defense towers to defend against them was not worthwhile.

In the early stages, we had no choice but to use it; otherwise, we couldn't hold out. We had to use it when necessary, and we didn't mind the cost. But now, using it extensively to continue fighting slimes is something I'm a little uneasy about.

In Yang Fei's mind, this increase in the number of monsters was actually a good opportunity for him to accumulate crystals.

But now it seems I have to bleed a lot of money. Giving up is absolutely out of the question. I just hope that when the million-level slime siege occurs, it will drop enough crystals to heal my wounded heart.

As the Slime King's Gaze and Peep were triggered one after another, Yang Fei easily completed this wave of defense amidst the mournful cries of the last gray-quality treasure chest monster. The two succubus girls commanded and fought in perfect coordination, leaving Yang Fei, a creature who could only perform one task at a time, completely dumbfounded.

Yang Fei even had some doubts about whether he was too incompetent, given how well the other team was commanding. Even if Yang Fei didn't want to admit it, it was the truth. For a moment, Yang Fei wondered if he should just lie down and give up, perhaps making the defense of the Sky Island easier?

"Congratulations, Trainee Lord Yang Fei-1! You have perfectly cleared the third wave of the Novice Trial on Easy difficulty and obtained the basic building blueprint - Residential Building. It has been sent to your system space. Please use it to your advantage in time."

"Please note that the interdimensional gate is about to close and the War Corridor is about to disappear. Please retrieve the defensive towers on both sides of the War Corridor in time. Countdown: 5 minutes."

With the timely appearance of the prompt, Yang Fei's scattered thoughts gradually returned to the main topic. The number of unenhanced slimes, less than ten thousand, was still too weak for Yang Fei's current Sky Island.

The various defensive towers took turns firing, and without even the two succubus girls needing to lift a finger, the towers, under the skillful control of the demons and humans, easily dealt with this wave of attacks.

The basic reward for this wave is a gray-quality house building blueprint, which can be used 10 times to build ten wooden houses. Under normal circumstances, these ten houses can definitely last a long time.

But for Yang Fei now, even if the house is full of people, it can't accommodate one percent of the current population of the Sky Island.

House Building Blueprint (Gray Rare): Basic building blueprint, costs 100 units of wood, 10 units of stone, and 1 gray energy crystal. It does not consume time or workers and directly builds a 100-square-meter wooden house at the designated location, which can accommodate 3 to 5 people.

Note: This drawing can be used 10 times. After 10 uses, the drawing will disappear.

The building materials for this house are very simple, especially since the first team that explored the Lost Jungle returned. And perhaps because it was a basic reward, it was even of gray rare quality, with the added benefit of automatic construction.

Normal gray-grade blueprints, or rather, the vast majority of construction blueprints, require providing workers and spending construction time, similar to the higher-level blueprints that can be used indefinitely.

This blueprint can actually be used for construction, which saves Yang Fei a lot of trouble.

Since it was a basic reward, and selling it to the Heavenly Dao Shop wouldn't unlock it, Yang Fei didn't hesitate. Plus, he had plenty of materials now, so he spent 700 wood, 70 stone, and 7 gray crystals to use the blueprint 7 times and build 7 houses.

There's no way around it. It's not that we don't want to use it all, but our already abundant timber reserves have dwindled after this round of use. The Lost Jungle can only produce 600 units of ordinary timber per day, and even with what we've accumulated before and what the various logging camps have produced today, it's not enough to build eight houses.

"Wooden House (Initial): A simple family dwelling with a fixed shape that cannot be customized. It occupies 100 square meters and includes a living room, a bathroom, and two bedrooms. It can accommodate 3 to 5 people, and it is recommended that the residents be a family, which will help increase the residents' favorability towards the lord."

Wooden House (Upgradeable): Costs 200 wood, 20 stone, and 1 gray crystal. Increases the house's footprint, transforming it into a three-bedroom house with a living room, kitchen, and bathroom, suitable for 5-8 people, ideal for a small family of around 7.

Seven small wooden houses, each slightly smaller than Yang Fei's cabin and with a completely uniform style, were positioned at locations Yang Fei had pre-selected, with beams of light shooting directly from the blueprints after Yang Fei invested fixed resources into them.

Seven standard wooden houses with stone foundations and wooden walls rose from the ground in an instant. This process made Yang Fei feel somewhat melancholy, especially when he thought of his home on Azure Star.

Ten people lived in that house. Although no one complained, it was still a bit crowded. Except for Yang Fei, each person had almost no private space and lived with several people together.

Winter is fine, but in summer, it really feels a bit uncomfortable.

Now, it's somewhat disheartening that a house so easily built, with a floor area much larger than one's own home, and where one can freely control the people living inside, with a maximum capacity of only five, is actually quite remarkable.
