Hi! I ordered a Likebook Mars and I'm expecting it in a few days, in the meantime. I've explored different options for rooting it and this is what I've done:
1) Download the new Android 8.1 update package
2) Unpack the update-10225.img file with imgRePackerRK
3) Copy the boot image to your Android phone
4) Download and install the latest Magisk Manager in your Android phone
5) Press Install → Install → Select and Patch a File, and select your stock boot image file
6) Magisk Manager will patch the image, and store it in [Internal Storage]/Download/magisk_patched.img
7) Copy the patched image from your device to your PC. If you can’t find it via MTP, you can pull the file with ADB:
adb pull /sdcard/Download/magisk_patched.img
8) Rename it to boot.img. Find the folder where you originally copied it from (update-10225.img.dump) and replace it with the unpatched boot.img
9) Repack the update-10225.img with imgRePackerRK and follow the update procedure as explained by Likebook

It's a simple process and should work reliably. If you get stuck in a bootloop you can redo the update process with original unpatched update-10225.img to get back up and running.
Once you have root access you can flash NanoDroid-microG-22.6.91.20200821 through the magisk app and you'll get rid of the battery sucking spying google apps while mantaining a fully functional system.
Another interesting option once rooted is to monitor any suspicious app sending data in the background. Now you can debloat/disable unwanted apps and have full control of your system.
