Are there any tricks to catch six-star heroes during the Warring States Period?

There is an awesome man in our family who caught six stars, so I'll share his experience with you. The first one is to go to the pub with a roller brush. If you are lucky, you can brush it out, probably dozens or hundreds of times. He brushed it, even if you ask for information, the second one should act as soon as possible, that is, when the information is refreshed, you will fly to a high place to fight immediately after asking, and you will be one step ahead, but these all need money. However, the awesome people in our family caught a lot, gave some and sold some. One of them trained to level 10 or above, provided more than 2000 RMB five-star equipment, and another one was awarded five stars, but the probability is very small, unless he is really good.
