LDPlayer is similar to BlueStacks with an easy-to-use interface, you also log in to your Play Store account to download other games on Android in general. You should download Chrome first because LDPlayer does not have Chrome by default.
With League of Legends: Wild Rift, LDPlayer allows downloading and installing APK files, you can download from APKPure and APKMirror.
Wild Rift APK download link: APKPure / APKMirror
Similar to LDPlay, MEmu allows you to read and install APK files easily. You can download League of Legends: Wild Rift from the link I inserted above via the APK file to apply to play on MEmu. You also need to download Chrome first to make it easier to download the file.
This is the button setup corresponding to your keyboard, you need to read clearly and set up the buttons in the game that you need to pay attention to. If you have played LMHT on PC, the 4 skills of the general correspond to the buttons Q - W - E - R. Normal attack uses the A button. Upgrade the thiif skill corresponds to 1 - 2 - 3 - 4.
Note that attacking towers and fighting monsters in League of Legends: Wild Rift will be separate, so you also need to pay attention to distinguish the two buttons appropriately.
Just use the mouse to control. Have fun!
