Welcome.

Backstory

The universe is collapsing. More importantly, your galaxy is collapsing. And you are stuck in the middle of it. You need a ship with an extremely advanced and powerful propulsion system to escape to the outer reaches and begin your journey once again. However, you are just a lowly rice farmer. How far could you possible get? So far, no one in the universe has succeeded in the researching of this propulsion system. Will be the first to ascend to the top? I don't know. The stars await an answer. And you are the only one who can provide it to them. So, go farming, Peasant, and we shall meet again soon.

Getting Started

To get started, you'll need some simple supplies to begin farming your way up to the top. You are given a small amount of rice, water, fertilizer, and money. You must build your way up to the top via farming, harvesting, and trading. To farm, you must click on the tile. To harvest, you must click on the tile again, after it is ready. There is a market ready for you to sell, buy, and possibly trade things. Our currency is yuan. We wouldn't have it any other way.
You may have noticed the different types of rice that exist. There exists to be plain rice, which is what everyone starts with. Select rice, which is an unstable type of rice that produces plain rice upon harvest, but in much larger quantities. If you are advanced enough, it may also mutate into a different type of rice, called brown rice. Brown rice produces its own unique type of rice, which sells for a much higher price than plain rice. You may also notice it doesn't have a 100% success rate upon harvest. Like its unstable cousin, brown rice can also mutate into gold rice, which is highly valued on the market, but also so unstable that its success rate is less than half. Hopefully this bit of information has assisted you on your journey.

Mid-game

(At XP level 20...) So we meet again. I actually didn't think you would make it this far. You have come a long way from your humble beginnings, as a tiny little peasant, with a tiny bit of land and supplies. Yet time runs low. Your galaxy is still collapsing. You must now accept your fate and begin the research phase. You have acquired the skill of collecting research as you farm, and gaining powerful and useful knowledge. Good luck. You'll need this research. Before you lies three huge steps that you must take to reach your final end goal. A unique award awaits you at the end of each stage.
Step 1: Before you can start working on the propulsion system, you'll need to learn basic physics and mechanics. These sets of experiments and concepts will require you 10,000 research and 10,000元.
Step 2: I know you are excited to continue, but you must now learn the concept of nuclear propulsion. It is rather powerful and useful in many facets, but is rather primitive in the speed category. Still, it is an important concept to know about, and you'll need it later on. To acquire this, you will need 100,000 research, 100,000元, and 100,000 select rice seeds, for the select rice is said to be extremely unstable (it's still safe to eat though).
Step 3: This is the final and most important step. You will now learn that the universe contains dimensions beyond the thinkable. You will learn to (literally) bend and distort these dimensions and use that to your advantage. This is the concept of curvature propulsion (a term coined by Liu Cixin), and this will require a grand cost of 1 million rice. In addition, it will also cost you 1,000,000 research (to actually figure out how it works), 1,000,000元 (for ship materials), 100,000 brown rice seeds, and 10 gold seeds to finish the final step.

Other Uses of Research

Your research is not only limited to researching curvature propulsion. You can also use it to advance your own farming. For example, for 5,000 select seeds and 5,000 research, you can increase the amount of brown mutations you get when using select seeds. For 10,000 brown rice seeds and 10,000 research, you can increase the amount of gold mutations that happen when using brown seeds. The technology for a more powerful fertilizer can be unlocked with 20,000 research and 20,000 fertilizer. Hope this will assist you in your journey to finally building that ship.
