Anyway, Ma Weiming is an electrical system, IPS and electromagnetic propulsion expert. He's not a naval architecture so one should take he's ideas with a grain of salt. There are lots of take in China about his 全能舰 concept but the most reasonable one I've seen is the argument that too much of a warship's internal space is devoted to storing chemical energy currently, weather that's fuel for the engines, propellant for main gun and point defence guns and solid fuel in missile's rocket motors. Compared to nuclear power chemical energy storage are extremely bulky and dangerous.
Instead in a 全能舰 almost all of the ship's energy comes from powerful onboard nuclear reactor, distributed out to subsystems via IPS. Propulsion is electric, main gun is replaced with railgun, point defence 1130 is replaced with laser DEW, even the VLS has some sort of electromagnetic catapult system built in to give the missile an big burst of initial kinetic energy so the rocket motor could be smaller. I think the plan also called for some sort of coilgun to defend against approaching torpedoes.
That way space usage inside the ship is optimised, instead of 30mm and main gun ammo storage taking up space and not contributing anything during a missile slinging contest, you just have an oversized reactor and switch power around the ship as needed.
