System: My Doomsday Train-Chapter 583 - 292: Seven-Color Region, Equator Core.
The cost to build a Level 20 Viper Unmanned Combat Aircraft is 5 million units of Titanium Crystal Ore, reduced to 2.5 million units after halving the consumption.
For him, a Level 20 is already somewhat insufficient.
A Level 30 is needed.
The cost of a Level 30 "Shuttle Ship" is 20 million Titanium Crystal Ore, reduced to 10 million units after halving the consumption.
Although the core has nothing to do with the combat aircraft, the scientific name remains "Viper Unmanned Combat Aircraft," just like the "Moldy Bread Slice Production Line," which won’t change names no matter how many levels it upgrades.
There are still 1.02 billion units of Titanium Crystal Ore inside the train.
Without the slightest hesitation.
He directly consumed 1 billion units of Titanium Crystal Ore to produce 100 Level 30 "Shuttle Ships," each embedded with a Level 4 Energy Stone. Out of these, 81 stones came from the former combat aircraft, with an additional 19 newly made.
It only cost less than ten million units of iron ore.
If the attack strength needs to reach Level 25 or even Level 30, Level 4 Energy Stones are not enough, especially since one Level 4 Energy Stone only requires 500,000 units of iron ore, and even with two "Half Consumption" Supermodel Effects, they can barely hold up.
But...
The Energy Stones on these combat aircraft aren’t used up; they can’t just be set aside unused. They’ll be used temporarily and replaced once exhausted. Spend where needed and save where possible.
...
The Constant Star Train was now sat at the edge coast of the pink area "Tropical Jungle."
This was a vast piece of land.
It’s possibly the largest area he’s seen to date, with a Target Detection Radar range of a full hundred thousand meters, yet still unable to detect the boundary.
"Zzrr... Zzrr..."
The roof of car number 10 opened, and shuttles took off from their spots, continuously hovering above the train for escort.
"..."
Chen Mang looked at the red dots on the Target Detection Radar, eyes slightly narrowed; the monsters in this area must be cleared; otherwise, the ore here would be difficult to mine.
Although his armor level is insufficient...
But—
He has plenty of copper ore.
A total of 2.11 billion units of copper ore, enough to fight a tough battle. Once all the monsters in this area are slaughtered, this area would be his paradise.
And 720 million units of iron ore.
That’s enough.
He turned his gaze to a red-grade component he’d ignored for a long time or hadn’t used, the "Earth-Burst Missile."
This component had always been Level 6, not upgraded.
The main reason was it was too expensive, fundamentally unaffordable, as crafting one Level 6 missile costs a full 300,000 units of copper ore.
"300,000?"
Chen Mang paused slightly, then couldn’t help but smile, lighting a cigarette and leaning against the chair, gazing somewhat dazedly at those numbers on the control panel screen... One Level 6 missile only costs 300,000 units of copper ore?
So little?
But why did he remember it as extremely expensive, considered only at crucial moments, never thought about usually.
In front of 2.11 billion units of copper ore, that number indeed appears too small.
People, huh.
When they become affluent, they often find themselves bewildered by what was unattainable in times of poverty.
The red-grade "Earth-Burst Missile" requires iron ore for upgrading, copper ore for crafting.
After consuming 17.2 million units of iron ore, he upgraded it to Level 30 in one go, obtaining two Supermodel Effects.
-
"Earth-Burst Missile Level 10 Supermodel Effect": Enlarges explosion range and increases power.
"Earth-Burst Missile Level 20 Supermodel Effect": Halves crafting consumption.
-
Level 5 Supermodel Effect, similar to Level 10, increases power but not the explosion range.
The cost for a Level 30 Earth-Burst Missile is 1 billion units of copper ore, and 500 million units after halving the consumption.
However, he doesn’t need such a high level.
The highest-level monster in the pink area, "Tropical Jungle," is Level 24; he only needs a Level 25 Earth-Burst Missile. With the missile’s power, once detonated, it could obliterate everything, and if any survive, a few more shots from the Doomsday Cannon would suffice.
The crafting cost for a Level 25 Earth-Burst Missile is only 800 million units of copper ore, halved to 400 million units.
The train’s reserves are enough to craft five of them.
But, just one is enough.
He immediately consumed 400 million units of copper ore to craft a Level 25 Earth-Burst Missile in car number 14, then gently said, "Ai, let the ’Shuttle Ships’ check out how large this area is, and see if all the monsters can be gathered together and treated to a missile."
"Understood."
The voice of Ai came from the train cabin.
Next——
The 100 "Shuttle Ships" hovering above shot out in different directions, the piercing blast of sound waves echoing through the sky as the thrusters on each Shuttle Ship’s tail emitted violet-blue flames.
And around the Shuttle Ships, there were several rings of purple light, similar to accelerators.
Which made the Shuttle Ship’s speed much faster than the speed of the Constant Star Train, and much, much faster.
"What’s the maximum speed of the current Shuttle Ship?"
"Much faster than the Constant Star, Train Captain."
"In the universe, it’s common sense and unavoidable that Shuttle Ships are faster than the Mother Ship, as the Mother Ship has more functionalities to handle, while Shuttle Ships only need to ensure speed."
"Quite good."
Chen Mang silently nodded, looking at the several green dots moving quickly on the Target Detection Radar; those lower-grade components might undergo qualitative changes after upgrades.
