Hello.
Answer to chapter 5.
The power like summoning lightning and flying is impossible and I am sure that noone ever did it in our world. Due to fundamental laws of physics and biology, most likely obtaining something like that for biological system without additional organs and changing the structure of organism won't be possible in other worlds either.
About ancient martial arts. When I was younger, I was a direct disciple of leaders of federations of Taekwondo, Wushu, and Wing Chun in my country. (sadly I put physics above martial arts in my life, so after applying to university I stopped practicing and I do not practice anymore for few years, but I still know a lot about it).
There are 2 ways of martial arts: inner and outer (english is not my native language, so name maybe different)
Inner styles are closer to cultivation so I would explain what I know about it. The main point of inner style is do not train your muscles, basically less muscles - the better. You see, most practitioners use body as mechanical system, but actually it is semi-mechanical, semi-hydrodynamical system. So the idea of inner styles practitioners is to generate Centrifugal force inside there body and perform a hydraulic shock. The 1st level achieved by inner practitioner is ability to perform fa jing (you can google it), later levels are much more formidable but you most likely won't be able to find any info about it because training it without master may kill you, So in nutshell, after 20+ years of training inner practitioner can kill almost any human just by touching him. My master was able to push a 70 kg disciple, who touched his shoulder, without moving any muscle by 2 meters. It is like he is vibrating all the time. Also inner practitioners are generally keeping there strength until the moment they die because they do not use muscles so old age almost do not affect there power (thats why exist legends about 90 years old masters stronger than young warriors). Also it is possible for a master to 'control' his weight, but actually it is just vibrating and constant applying of force. It is an increase or decrease of mass, it is only a correct momentum. Also when martial arts were a real thing all martial artists had some medical knowledge and even now some traditions ask it for applying for better dan. My master of Wushu even was a practicing therapist in our local hospital. So as you may see they were able to use herbs and acupuncture for better recovery and boosting perfomance during battles. Natural drugs are quite strong actually, and can boost your speed and strength above limit of your body. (it is harmful, but trainied body can endure it once in a while)
I think you got an idea what were martial artists of ancient times. Real martial artists were truly strong and things like dodging arrows or moving unharmed through an army and killing general was a reality. And even ‘’magic powers’’ existed, thou it was only correct usage of herbs and explosives. (gunpowder was known even before 700 AD, but became used in wars only near 1400, so those 700+ years was the golden age for people with some knowledge in alchemy).
P.S. They are not hiding, they just know that purpose of martial arts is killing and we live in peaceful times where violence is prohibited. Going to war zone is a terrible idea either because explosion or bullets are much more effective then melee. Due to this reasons, basically only leaders of federations and there successors learn properly., Most disciples are not taught real arts actually. It happens because people refuse to invest years of there life to something that won't help them in future.
Have a nice life and do not think about useless things!
