Siheyuan Mogul: Starting with Ten Trillion

High school graduation + no System + feel-good power fantasy + lottery + aliens + beautiful women, with one satisfying moment after another. The author is a bit of a jerk from the start, so please go easy on them!!

The first-prize ticket in the Cosmic Lottery is worth 10 trillion cosmic coins, and a born loser from the slums wins it. After fleecing lottery players across the universe's major star systems, Shen Lang begins a shamelessly extravagant life on Earth. “An LV bag costs over 60,000? You country bumpkin, get lost.” “Hello, I bought your store!” “A Ferrari costs 15.8 million! Can you afford it, you loser?” “Sorry, I bought the whole store!” “Sir, could you play chess somewhere other than the intersection next time? It's dangerous!” “Who owns the road, you?” “I want to develop this urban village...” Just as Shen Lang is slacking off, a group of cosmic bandits from some planet called Shénmǎ arrive on Earth. From then on, a hilarious battle of wits and wealth unfolds between the bandits and this nouveau riche. Then Shen Lang discovers that spending has been restricted on his cosmic account. That's absolutely unacceptable, so he subdues a bunch of cosmic nobodies and sets off for life on an alien planet. Even there, with his 10 trillion, Shen Lang can still crush every other tycoon, until the wealthy young masters of certain cosmic clans set their sights on him. Trouble is coming...
