Hi, “Herlambang”
Do not worry about your English, it is just fine.
If I am correct, what you want to learn is how to play lead guitar, and be able to play fast passages.
Try searching the Web for “lead guitar” or “shred guitar”. in your own language.
Please let us know what language you speak, maybe other members here speak the same language as you and they can help you.
A good place to start learning lead guitar is the study of Scales.
Here is a common scale pattern for the “C Major Scale”

E-------------------------------------------------------------7--8----
B----------------------------------------------------8--10-----------
G----------------------------------------7--9--10-------------------
D----------------------------7--9--10-------------------------------
A----------------7--8--10-------------------------------------------
E---------8-10------------------------------------------------------

Play that scale at the desired speed using a metronome.

I hope that helps a little.
