Ok, I did it alone. With this procedure you can root any MTK Device (maybe every Android device).
1. I download new Magisk Manager and Magisk zip installer.
2.I create patched boot image into Magisk.
3. Then I share patched boot image to my computer via USB cable (USB debuting into device must be enable of course) and turn off MTK device.
4. Next I unlocked bootloader via cmd windows console and install patched boot image in fastboot mode via the same way (cmd)
5. After that I turn on the device and installing Magisk zip package. And got root without any custom recovery.
