To summarize in three points, these are the most effective and direct methods for catching TJ pets. If you're interested, feel free to give them a try. In reality, catching TJ pets largely depends on luck. If your timing is right, you might not even need anything and still catch one easily, just like my apprentice did. He often catches pets and refines elixirs, but he keeps catching TJ pets (although not all of them are good ones, haha). So, I hope that during your free time, all players can do more good deeds and earn some "RP" (good luck), which will likely increase the chances of catching TJ pets. Good luck to everyone!
3. Use the Attraction Spell. This method is more suitable for players with plenty of Yuanbao, as the Attraction Spell increases the chances of catching a TJ pet, but it is quite expensive. Therefore, it's generally not recommended for regular players, but those with abundant Yuanbao should consider it, because catching a few more TJ pets and selling them will cover the cost.
2. Buy Old Wine. Old Wine can be purchased with Yuanbao, but it's relatively inexpensive. After buying the wine, invite the fortune-teller to drink it. When the fortune-telling reveals a TJ pet sign, immediately go and catch a pet (since drinking with the fortune-teller may also result in other signs, this again depends on your "RP"). The probability of catching a TJ pet using this method is higher than usual.
This is the most tedious yet cost-effective way: catching monsters in a fixed location. Many friends might say that this method limits the number of pets you can carry, making it inefficient. Here’s a tip: don’t carry too many items in your bag, only bring necessary medicines, then go out and catch pets—whether they are babies or wild ones, catch them all (anyway, TJ marks cannot be removed). Pets without TJ marks can be used to refine elixirs, and multiple elixirs can be combined into advanced ones, which can be sold on the market, achieving two goals at once.
