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

The Slime King's Gaze triggered a bit early this time, but the monster spawning efficiency on Hard difficulty remained unchanged. In addition, with Yang Fei's gray arrow tower going all out, the two tentacle jellyfish retreated a short distance, making this defense easier than the previous wave.

Even though he was caught off guard, Yang Fei remained calm. While loading the ballista, he also observed the battlefield. If acid slimes appeared, he would attack them first; otherwise, he would kill the regular slimes.

The two arrow towers were the same; they prioritized killing the corrupted slimes that appeared on the battlefield, instead of quickly killing the regular slimes, which led to a rather strange situation.

There were clearly many more monsters, but because Yang Fei didn't slack off this time, his killing efficiency increased. The two tentacle jellyfish were not as fast as the previous wave when they were waving their tentacles. The two little guys even had time to start waving their tentacles once more and launch an all-around attack on a slime.

Logically speaking, this wave should have been more difficult, but in Yang Fei's opinion, it was actually easier than the last wave. This was not only because he worked hard enough, but also because the Corrupted Slimes in the last wave spawned in clusters at the end, which would draw the firepower of the two white arrow towers, thus increasing the pressure on the two little guys on the front line.

Now that they're mixed together, and with the two little guys retreating, the defensive towers have better space to deal damage. Since the monster spawning efficiency hasn't increased, fewer monsters are getting in front of them.

Soon, with Yang Fei's full output, the number of remaining monsters on the blue gate was reduced to zero. Yang Fei controlled the three arrow towers to clear out the elite slimes in the war corridor and then reduced the number of ordinary slimes.

In the end, only 6 slimes remained, which were left as experience points for the two little guys.

After confirming that the two little guys could hold their own against the six slimes, Yang Fei plopped down on the ground. He was in a terrible state, his hands completely exhausted from pulling the ballista for so long.

Even with the help of the ballista, it still takes physical effort. One or two times is fine, but Yang Fei pulled it thirty-three times, and now he doesn't even have the strength to lift his arm.

Moreover, this is not the most important thing. What is more serious is the mental exhaustion. Yang Fei not only has to aim carefully, but also observe the battlefield at all times and kill the acid slimes at any time.

With his physical strength at its limit, multitasking, and intense mental concentration, Yang Fei was really struggling.

Leaving the six slimes for the two little guys to kill is secondary; the more important thing is to catch my breath and not end this monster siege too early, otherwise I'll have to rush back to the sky island to clean up everything.

"Congratulations, Trainee Lord Yang Fei-1! You have perfectly cleared the first wave of the Novice Trial on the Hard difficulty. You can start the next difficulty monster siege at any time."

"Congratulations, Trainee Lord Yang Fei-1! You have successfully completed the first wave of the Novice Trial on Hard difficulty and obtained the Basic Building Card - Lumber Mill. It has been sent to your system space. Please place it 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."

He had barely caught his breath when the familiar notification sounded again. Yang Fei sighed, dragged his tired body down the defense tower, and returned to the Sky Island with the two slightly excited little guys.

With the arrow towers back in place and collected with a single click, Yang Fei lay down on his own floating island, closed his eyes, and didn't want to say a word. He circulated his True Qi Technique to refine the large amount of True Qi accumulated in his body to replenish himself. Resting was the only thing he could do right now.

Half an hour later, Yang Fei, who had refined a small portion of his internal energy, finally recovered and looked at his system inventory to check his gains.

One green-quality slave trader summoning token, one hundred catties of white rice, ten catties of Qi rice, one bag of Qi rice seeds, one basic building card - Lumberyard, 70 copper coins, 66 pieces of bio-rubber, one gray-quality arrow tower card, and three gray-quality energy crystals.

The gray-quality arrow tower card was dropped by the first acid slime he killed. The other acid slimes were also killed by Yang Fei, but they also dropped bio-rubber and copper coins, which looked exactly the same as the corrosive slime.

While it's impossible to make a valid comparison in terms of quantity, this seems to be the best item it can drop. As expected of a variant of the Corrupted Slime, the drops should be the same for both.

However, I don't know what's going on with the drop rates of the other items. There doesn't seem to be any pattern. Perhaps different difficulties also affect the drops. So, the more difficult it is, the better the drops should be. But why was there only one crystal this time? Is it just a matter of probability?

Yang Fei was a little confused, but he didn't want to think about it too much. His daily card-drawing talent was a random thing, and he might have bad luck and die tomorrow, so there was no need to think about it too much. He should just treat it as a matter of luck.

"It's 11 p.m. right now. The gray arrow tower still has 63 energy points. The two white arrow towers will need another half hour to fully recover their energy. I took about twenty minutes on the real hard difficulty, so the corresponding daily challenge should be easier than that."

"Although there are some limits, I don't need the crystals for now. Fortunately, the worst-case scenario didn't happen." Yang Fei finished calculating his gains, then estimated the most important daily challenge of the day, and finally breathed a sigh of relief.

Based on this calculation, I should be able to save the three energy crystals I own. The first wave of monsters at the highest difficulty usually consists of 500 monsters. If I want to maximize my profits, I will definitely need to use crystals. Moreover, this is not a normal situation, and the number will only be more.

For the highest difficulty, it's best to calculate based on 600 enemies. Although the numbers won't increase, the full energy accumulated by the two white arrow towers can take down nearly 200 enemies. Adding the three gray crystals, that makes 500 enemies, leaving a shortfall of 100 enemies.

"The nest will refresh tomorrow, and even if I recruit another tentacle monster, it still won't be a perfect clear." Yang Fei sighed. Unless his card-drawing talent has another amazing stroke tomorrow, giving him a white arrow tower, he might not be able to clear the level perfectly. Otherwise, the city walls will definitely lose health.

Although the basic reward on the hardest difficulty is a quarry, and you can harvest a fixed amount of stone every day as long as you send people in to work, it feels a bit wasteful to use stone to repair the city walls in the early stages.

The market price for one unit of stone is one copper coin. Instead of building towers, it's better to buy defensive towers, since defensive towers can be used for a long time, while building city walls is only done as a last resort.

"Slave Trader Summoning Token." Yang Fei looked at the special item in his system inventory and hesitated slightly. If he could use this thing, it might be the most profitable way.
