With direct extrude i did not suffer from travel line, but when i switch to bowden extrude then the travel line shows up.
I set the retraction value to 9 because when i do those retraction test which can be found on Thinginverse none of other numbers make a difference.

Maybe a bit simple minded here.. but do you have the Combing mode on in Cura? its under the travel section.
Combine mode set to ALL and Z hop when retracting is disabled.

If you mean the single diagonal lines, these are not scars but sort of "travel lines" (I don't know the official name), where the nozzle travels from one point to another without stopping extrusion. I guess the idea behind this is that this causes the least amount of pressure- and flow change in the nozzle, and thus the most stable temperature and extrusion? But I don't know if there is a setting where you could turn this on or off. I just consider it part of this specific production method. Like seam lines and ejection marks are part of the injection moulding process.
I switch from direct extrude to Bowden setup and then the travel line show up. I also cut the teflon tube to minimize the distance from motor to hot end but same result. Sometimes i hear click on extruder motor. My step/mm are at 100. And the calibration show that i am extruding the exactly 100mm.

How to remove scars from top and bottom of my print. I have try to reduce Extruder steps also change retraction distance to a higher value but no success.
Here is my printMaterial BLack Pla Layer Height--0.15 Initial layer height --0.15 Wall line Width 0.4 Wall Thickness - 1 Wall Line Count - 2 Top Bottom Thickness - 0.8 Top Layers 6 Bottom Layers 6 Infill - 10% Inital temp 215 Temp 207 Retraction Distance - 9mm Retraction Speed - 60mm/s Print Speed - 40 Infill Speed - 100 Travel Speed - 100 Initial Layer Speed - 20.0

Hello,
I print this box and when i remove from the bed the layer before infill just rip off.
What can cause this?
A miss configuration in Cura?
Thanks
