Beginner/playeble against everything Opening for White
What you are looking for is a natural opening without a lot of book. The Reti (1. Nf3) and the English (1. c4) are good options. Sound, easy to master based on opening principles (quick development, control of the center), and a lot fewer well-studied lines than 1. e4 and 1. d4 systems.
Since you're probably trying to avoid complications, I'd recommend the English for you. I play the Reti, but beginners aren't usually comfortable with unresolved positional tension, which is a must-have in the Reti.

if you press learn you can go to openings too (don't press learn that will bring you to lessons, just put your mouse on learn if you are on computer and select openings)

1. Nf3 is not the Reti. 1. Nf3 followed by 2. c4 is the Reti.
1. Nf3 and 1. c4 are terrible opening moves to recommend to a beginner! The reason for this is quite simple: they often transpose into almost any other opening, and allows Black to choose!
For example, 1. Nf3 c5 invites the Sicilian (if White plays 2. e4) or a Symmetrical English (with 2. c4). 1. Nf3 d5 invites Queen's Gambit, Nimzo, and QID lines. 1. Nf3 Nf6 invites several more. There is no way a beginner is going to navigate all the transpositions without getting frustrated!
The English is similar. It can often transpose into Queen's Gambit lines, or Catalan lines, or Reversed Sicilian lines! All of these are completely different.
The OP is looking for a unicorn (an opening he can play on auto-pilot to get to the middlegame), but suggesting the most transpositional first moves is not a good choice.
To answer the original question:
There is no "universal system" that can be played against anything Black throws at you. The Colle, London, Torre, and KIA are the closest you can come, but each of those have their own drawbacks. In general, beginner players should stick to 1. e4 or 1. d4 (preferably 1. e4 to begin with) and learn to play using general opening principles (control the center, develop your pieces quickly, get your king safe, don't move the same piece twice until you have finished your development - all unless there is a tactical reason you must!)
If you want to choose an opening setup to study (you shouldn't at this point, but if you insist), find a top player you enjoy watching/studying and play what they play (you may want to check out some Banter Blitz videos on YouTube and see which players have games you would like to play). For example, if you like watching out MVL plays White, learn the Italian or Spanish and use his games as models. If you like watching Ding Liren, learn the Catalan and use his games as models. Etc.
umm... kings gambit or queens gambit
Yes. I play the kings gambit all the time, both here and chesskid.com, and many of my opponents don't know enough opening theory to counter it.

I recommend to play 1.e4 or 1.d4, nothing else for now.
Perhaps even 1.d4 is a stretch for your level as d4 involves more positional knowledge because of more quiet positions.
Don't do the Reti, whether it be the traditional Reti, the Reti Gambit or the symmetrical Reti openings.
The Reti is for advanced players like @PawnTsunami said, I would recommend the start of a Reti player to a 1600, but I believe a player perfects the Reti when they get to 2200+ or somewhere near the master level, but even so it is not an opening mean't for earlier players for the previous mentions said and more.
Like I said d4 could be a stretch and don't recommend that opening until like 1200-1300 when you have a certain understanding of the game and some wins under your belt.
1.e4 is the most traditional and straightforward option for now, I would avoid hypermodern openings(again like the reti) or any systems as that is not real chess. Sure using systems like the Colle and the Torre is nice, but if you want to stick to a great system use the London. Other systems in my eye's are, lets say questionable. I say this because they can be broken through and for a beginner it can be good but once you hit the 1300-1400 range those openings will backfire quick and with good reason.
Bottom Line: Stick to e4 and the openings in e4 and occassionally d4 with some systems under your belt that are proven to be good, however don't start any openings that really too heavily understanding as for now you are just no on that level.

For black I heavily recommend you get good at the Kings pawn opening(e5), the Sicilian defense (c5), the caro-Khan defense perhaps(c6)[also depends though are you more of a quiet player or a attacking player]. I recommend you study these openings now as they are good and if you play them correctly and study the basic theory it can get you to good positions.
Moreover not now, but later on like when you get to the 1200-1400's I tihnk studying the french defense(in classical time, rapid, or blitz) and the pirc(in bullet or 3-5 blitz games) would be a good idea as you will have more understanding of the game and on top of that if you study the theory you will be well prepared for your opening preperation against e4.

" I find the london to well known and people know how to destroy it."
As far as I know, every single sound opening can be met by at least one efficient answer. There are good defenses against the London, but they don't "destroy" it, else no one would be playing the London in tournaments etc. Don't pick an unsound opening (e.g. the Durkin attack, a.k.a. the Sodium attack: 1.Na3) in order to play something your opponent doesn't know how to counter precisely.
Don't be afraid of the London for that reason.
Not learning a system doesn't mean learning huge amounts of theory. Here's an interesting suggestion (not mine) for beginners about an almost complete repertoire for white, based on 1.e4: https://www.chess.com/forum/view/chess-openings/should-i-switch-my-openings#comment-48661360

I always been successful with the Lodon for a long time, I think it is a fairly solid opening that is hard to break through of course you have to play better moves, but it is a great opening depsite the "breakthroughs" you are mentioning.
No offense my friend.

Thanks alot guys for all the answers I never expected so much answers but thanks for explaining and telling me some new openings

You can play 1.e4 2.Nc3 against everything black throws at you without too much trouble. It's probably worst against 1...b4, but I think you can cope.

It is always good to help out a fellow chess memeber, just glad you are being helped but us fellow people.
Remember to play hard and enjoy the game as well!

Forget openings all together. You are 700 rated and all your games are decided by someone hanging a peice. The least of your worries should be someone knowing how to "destroy" the london system. Which obviously isn't possible considering the world champion uses it in serious games.
Hello guys, first forum post.
I am searching for a opening to play as white.
I am searching for a opening like the london system (Playeble against all defences, Easy to play)
But I find the london to well known and people know how to destroy it. You guys know any good beginner openings?
