In fact, even the best equipment has no limit. If you just want to see how many 70 belts others have, you can go to Yezi Pig to see the all-in-one exhibition. I want to buy the best for my own use, and what suits me best is the best. Generally, the 70 bands are 140 (anti-30), 150 (anti-40) and 157 (anti-42). The first blood band of 70 ordinary 240 needs 1, 5-2 million, 250 needs more than 200, and 260,270 needs 30,000-40,000. There are few higher ones, and others are willing to sell them. You'd better bring a stunt for your own use, such as unsealing water, adding blood to your heart and bringing you back to life, depending on your sect.
