The only pity is—
This "Fixed Star" can only support the train by providing energy for speed, it can't be used for other components. If it could be used for the "Akanon Light Energy Main Cannon," that would be great. A single fixed star is equivalent to massive amounts of ammunition; imagine how many shots you could fire.
Directly equipping the Akanon Main Cannon would turn it into a rapid-fire cannon.
The next step is to upgrade the Tail Spray!
The strongest seven-color level tail spray within his train is the "SPY-7 Doppler Tail Spray," which he upgraded to Level 200. This is a component purely based on numerical value, without any mechanisms. From Levels 5 to 200, the supermodel effect at each level is a sharp increase in speed, with no additional mechanisms.
Absolute values bring absolute numbers.
With the support of this component, the train's speed has reached 3.37 million km/hour!
This is an extremely frightening number.
But there's still a limit.
