Travel Through Time and Become Liu Bang with a Starting Capital of 5 Million

I accidentally activated the system and was about to travel through time to become Liu Bang, but before that, the system gave me a start-up capital of 5 million, a one-month deadline, and an unlimited warehouse. So in this month, I started a crazy buying and buying mode. I brought history books with me. I am blind to history. It will be easier to communicate when the time comes. Bring medicines, generators, power bank, buy everything you can for him! Some people say: The bravery of Yu is unique throughout the ages? Then please take a look at the sniper rifle in my hand, Liu Bang, and then talk. The characteristics of this book are, in one word, cool! Two words, very cool! Three words, you know.
