After entering the game, click the "Penny Store" option.

In the store, find and buy the "Travel Log". In this map, you can find the boss Raiders of each level and the number of stars needed to unlock the new world. As long as there are travel notes, you can start to record the customs clearance experience of players.

When the player has a travel diary, you can see it when you return to the main interface (at the bottom of the screen). Click to view the unlocked travel brochure, and you can read and share it.

The above is how to use the "Plants vs. Zombies Travel Manual" for your reference. Consult a professional for more accurate information.
