Grinding ingots… Use the same method as in this site's post, activate – unsubscribe!\This method can only be used once… more than that won't work… China Mobile has also fixed this loophole, at most you can grind 1,000 ingots, meaning if you send it again, it will reply saying that after verification, since you have requested many times, the subscription will not be refunded, or you will be directly blacklisted by China Mobile, with no reply to ingot messages.\Magic Diamonds! I currently have 3 Magic Diamonds! I got them by chance! This method is not completely free! At most it deducts 2 yuan or nothing. Method: Around 10 minutes before midnight, log into Home, click Magic Diamonds to activate twice, then collect two activation messages and activate one. Send the unopened message and the unsubscribe message (send the activation first) one by one (please manage the time difference carefully!) It must be sent at exactly midnight; a few extra seconds are okay. You will get one activation and unsubscribe success message. Because of the next day, China Mobile's system refresh won't record the messages. Check if the Magic Diamonds light up; if not after 30 minutes, try again. If it lights up, half is successful! Key point! If you don't deduct the fee immediately after activation, you will have a 3-day trial. Close to the 3rd day, prepare 3 activation messages and 2 unsubscribe messages 30 minutes in advance, send a distracting message, then activate Magic Diamonds again. Since Magic Diamonds were already activated, if activation fails, immediately send (first) unsubscribe (then) activation to get unsubscribe success and activation success messages. Done, you can take a sip of water and wait for midnight. One minute before midnight, send unsubscribe and activation; exactly at midnight, two messages will come: unsubscribe success, activation success. Why send messages with two in between? Because China Mobile and Tencent are smart! They aren't dumb, they know people might be cheating, so the system records everything. If daily unsubscribes and subscriptions exceed 3 messages, you will be blacklisted. But the system refreshes daily and deletes the records, especially when the trial expires, it's looser! So that day is the best day to grind! If that day China Mobile fixes the loophole, you would lose, right? Tutorial finished, tested in Guangxi! Other regions test yourself! Don't blame me for the fee! Grinding depends on luck! It's all about managing the time difference! If you're unlucky, you won't even help an old lady cross the street!
