This achievement is for ascending once. As the other solutions already detail, this is first doable either by 1) Spending 50 rubies and doing a quick ascension, or 2) Leveling up Amenhotep to level 150 and researching his Ascension upgrade.
I have been playing this game on a daily basis for over two years now on PC, and consider myself an expert on this game (although the console version is slightly different from any version that has been released on PC). I am currently up to around zone 21,000 on PC.
I would recommend
against spending rubies for a quick ascension this early in the game. Quick Ascensions are definitely worth doing later on in the game - it's perhaps your best use for rubies based on the current version of the game after buying the double damage upgrade, which should unquestionably be your first purchase with rubies (on PC you can purchase autoclickers with rubies which is generally a better use of them, so if you believe the console version will eventually be updated to include this, which it probably will, you may be better off saving your rubies to purchase autoclickers after you purchase the double damage upgrade).
What the other solutions also do not go in to is
when it is most efficient to do your first ascension. The best time to do your first ascension is going to be somewhere around zone 140-160. It's not an exact science - the ultimate goal of your first ascension is to maximize the number of hero souls you will gain after ascending. I will note the FAQ that I link to below suggests 160 for your first, but I think anywhere between 140-160 would be okay assuming you weren't particularly unlucky about gaining HS early on.
After zone 100, each boss zone will have a chance of being a "Primal" boss. The base value for this is 50%. That means when you get to zone 105 for the first time, there is a 50% chance of this boss being primal. You can tell when a boss is primal if it says you will gain hero souls just above the boss' life bar. One of the ancients you will eventually get, Atman, will increase the odds of bosses being primal (up to a maximum of 75% in this version of the game, excluding bonuses you get from relics). When a boss is "Primal" it will reward you with hero souls when you defeat it (for a maximum of one time per zone, so you can't just sit there at a primal boss racking up hero souls). Primal bosses will also have some swirling souls around them visually. These hero souls will not be rewarded to you immediately - they will only be rewarded after ascension. This is why it is
critical that you don't ascend too soon just because the option is available to you. If you ascend as soon as it is available, it is likely you will gain only 2-3 hero souls. That will mean that your new ascension will go almost exactly as slow as your first one, which is something you want to avoid. The whole basis of the game is to maximize the number of hero souls you get each run to make gaining hero souls faster in future runs.
At around zone 145, unless luck has been very unfavorable to you, you should have about 8-15 hero souls from boss zones 105, 110, 115, 120, 125, 130, 135, and 140, and from leveling up your heroes as much as you can. On average four of these zones should have had primal bosses that reward you with hero souls, but you may be more or less lucky depending. If you are satisfied with the number of hero souls you have by zone 140, that is about the earliest I could recommend ascending. Likewise, the amount of time to progress beyond zone 160 or so is more trouble than it's worth compared to the rewards.
A good way to help determine if it's worth staying in your current ascension vs. ascending immediately is to progress to the next boss zone just to check if the boss is primal. For example, let's say I have just beaten z145. At this point I would go through all the way to beating 149. Obviously I would have to spend a long time building up gold to have a chance at defeating the boss at z150. However, it may not be worth spending that time if I know the boss at z150 is not primal. Therefore, after defeating z149 I would immediately go to z150 to check if the boss is primal. "Primal" status will not go away, so you are free to check to see if the boss is primal and then leave the zone without defeating it. If the boss is primal I would know it's worth my while to stick around and build up gold, otherwise I would immediately ascend and make my second ascension faster (your DPS goes up with the number of hero souls you have. I will also mention it is a very bad idea to spend all your hero souls on ancients right away, you need a reserve of hero souls to increase your DPS, so only spend at most half of your hero souls until you gain the ancient Morgulis, which is about the 10th priority ancient you should be getting with your hero souls. While this isn't the best place for this information, since it's nowhere else on TA, I will say here that the ancients you should get first, assuming you want to go with a typical idle build, are Libertas, Siyalatas, Mammon, Dora, Mimzee, Atman, and Solomon. It's worth re-rolling until these show up as options. Once you have these and level them up regularly you should have a good system in place to regularly ensure you get a steady and increasing flow of hero souls coming in each ascension.
I will also mention that before your first ascension you should be trying to maximize the number of hero levels you have. You gain 1 hero soul upon ascension per 2000 hero levels. Later on in the game a paltry 1 HS for 2000 levels is utterly irrelevant, but for your first 40 or so ascensions this is going to matter a lot as an extra few HS will be useful.
There's a great calculator that works well for this version of the game located here:
http://hsoptimizer.github.io/ancient/This calculator won't tell you when to buy ancients or what ancients to buy next, but it does tell you the most efficient use of your hero souls amongst the ancients you own.
Finally, there's a great FAQ on the game that I would strongly urge you review, located at
https://www.reddit.com/r/ClickerHeroes/wiki/index While that FAQ is for the current version on PC, much of the information and strategies there are still relevant to the console version.
