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

Seeing the flamethrower tower beside him already spewing flames, Yang Fei fell into deep thought. Then, as if he had thought of something, he looked back at the city wall. At the edge of the sky island, a black giant tower was slowly falling asleep. Sensing the faint connection, Yang Fei put on a faint smile.

"Congratulations, Trainee Lord Yang Fei-1! You have perfectly cleared the first wave of the Novice Trial in 2x Extreme Mode. You can start the 5x Extreme Mode Monster Siege at any time, or you can directly choose the second wave of the Easy Mode Monster Siege."

"Note that after selecting the second wave of easy difficulty monster siege, you will never be able to challenge the remaining doubled extreme mode of the first wave again."

"Congratulations, Trainee Lord Yang Fei-1! You have perfectly cleared the first wave of the Novice Trial, the 2x Extreme Monster Siege, and obtained the Basic Building Card - Lumber Mill, which has been sent to your system space... Countdown: 5 minutes."

As expected, the Ice Slime appeared at the beginning and betrayed many of its own kind. Also, because Yang Fei had built the Fire Tower in advance, this wave of monster attacks, which suddenly "increased the difficulty," was actually easier to defend.

Seeing that everything was normal, the succubus ordered the two half-baked inferior demons to stop attacking. She then single-handedly depleted the energy of the three gray arrow towers, and together with the traitorous slime, they inflicted nearly a third of the battlefield damage.

Yuichi lived up to expectations. Unlike its two unreliable counterparts, it performed flawlessly. It burned almost all the slimes that passed through the first line of defense after consuming all four crystals. Some slimes were burned twice as expected, leaving them completely under the tower.

Yang Fei's ice arrow tower hadn't fired a single shot, nor had it replenished the energy of the white arrow tower. The white arrow tower, in conjunction with the ground troops' blocking, easily killed most of the slimes.

After leading all his subordinates back to the Sky Island, Yang Fei collected all the dropped items with one click, returned the defense towers to their original positions, and looked at his system space: 800 copper coins, 5 silver coins, 18 gray crystals, 3 gray arrow tower cards, and 288 pieces of bio-rubber.

"391 copper coins, 3 silver coins, 8 gray crystals, 2 arrow tower cards, and 120 pieces of bio-rubber."

"Two of the silver coins are guaranteed drops from the first kill of either of the two new slimes, since these two slimes don't drop any other items, so the first kill will always drop the best items."

"Copper Coin Slime will always drop one copper coin. Excluding the first one that appears, there are 49 more, which is 49 copper coins. Silver Coin Slime will always drop 5 copper coins. Excluding the first one that appears and the lucky one, there are 40 copper coins. Adding them together, there are 89 copper coins. That means the remaining slimes dropped a total of 302 copper coins."

Yang Fei took a breath, feeling a little cheated, though that was only from his perspective. Actually, the drop rate in this battle was acceptable, considering there were still 120 bio-rubbers, two cards, and eight gray crystals.

Compared to the 5 gray crystals spent on defending the city, this income is already quite good. However, the previous purchase of the fire tower and white arrow tower had cost too much, causing Yang Fei to subconsciously compare the two and always feel that he had lost out.

After arranging for everyone to rest or cultivate, Yang Fei built the newly acquired lumber mill and had a lesser demon put it to work. Then, Yang Fei returned to Azure Star to visit his younger siblings before returning to Sky Island.

It was already 1:40 PM. Taking advantage of the time and the relatively relaxed defense, Yang Fei prepared to challenge the next wave of monsters at 3:00 PM. The 1.5x attribute boost in the five-times extreme mode was not too high, because the attribute bonuses of the existing slime types did not exceed the range of killing them with the help of fire towers and arrow towers.

However, if it's a double attribute bonus under the ten-fold limit, it would be a bit difficult for Yang Fei now. After all, the Corrupted Slime with the highest HP has a full 90 HP, and after double, it would have 180 HP, which exceeds the range of 60+100.

The second-highest HP slime also has 80 HP, and after double HP it will reach 160, which is just within the kill range. Yang Fei should think about it carefully. At the very least, he should buy another fire tower before he can challenge it. But there is a classic question: will he be able to recoup the gray crystals he consumes?

The flamethrower is good, but storing only thirty attacks is too few. Even if you maximize the use of each attack, you can't guarantee full wave coverage if you only consider the return on crystals.

If Yang Fei wants to meet the unpredictable challenges ahead, he must keep the growth and storage of crystals in a positive number; otherwise, he is essentially paying the price for his own death. Yang Fei must have this sense of crisis.

Buying another fire tower is an option, but whether it consumes crystals or silver coins, it's uncontrollable. Moreover, Yang Fei isn't sure if any of his remaining inferior demons are like Yuichi. If those two skilled with ballistae have a higher accuracy rate, Yang Fei will take this gamble.

However, Yang Fei can't gamble for now, and those two aren't likely to improve their accuracy anytime soon. Therefore, this next 5x multiplier is crucial; it mainly depends on the increase in monster numbers and how many crystals drop to determine the next development plan.

If the monster population growth remains around 200, then the maximum number of monsters at ten times the limit would be around 1500. If this number is exceeded, and considering that ordinary slimes make up more than half of the elite slimes and corrupted slimes make up about one-third of the elite slimes, then buying an additional flamethrower might be more worthwhile.

However, if the number is less than this, Yang Fei felt that buying another fire tower was not worthwhile. After all, it only takes five crystals to replenish the energy of all five white arrow towers. For the corrosive slimes that can dodge the killing blow, there are really not many left.

Purchasing a flamethrower tower is still a priority to maximize efficiency, but the combined damage of two towers (120) is insufficient to kill more than half of the regular slimes, requiring additional arrow towers to finish them off, making it a poor trade-off.

Even when placing arrow towers behind to finish off enemies, you should still go all out on firepower, unless the ground troops continue to be positioned further back, blocking all slimes within the range of the flamethrower towers, forcing them to activate the flamethrower towers when they are numerous and clustered together.

But that would put the Corrupted Slime into the Arrow Tower group. As mentioned before, the automatically attacking Arrow Tower group is not very intelligent. Once a priority is set, they will definitely prioritize killing the pre-set units.

60+100+60这种情况基本不可能在自动攻击下发生，只会60+100+100，那按最高180的血量，感觉还不如100+100呢，也就是不如两座箭塔一起攻击或者一座箭塔直接攻击两次来的比较划算。
