Pixel Federation Trainstation game - very quick level up, no cheat or hack used

In this video you see how, I went in 33 minutes from level 533 to Level 618.

No tricks, no hacking - all I needed was 72 billion in-game gold to invest.

I bought and sold "WAGR S Class" engines in 5 batches - 2500, 2500, 2500, 1500 and 1000.

This stunt cost me 71.157.859.799 gold, but I gained 85 levels, 170 diamonds and 2.258.999.145 XP points.
