Basically prep the surface relatively flat and adjust slope for drainage.. assuming that it is the yellow/red mud that is rather devoid of nutrients.. no worries.
Lay out a newspaper covering the whole area. (per https://www.getgreenbewell.com/newspaper-pr...-in-the-garden/ )
Pour fresh topsoil/(50-50 weed-free potting mix + sand) over the newspaper.
Sprinkle real bermuda grass seeds all over (e.g. https://www.lazada.com.my/products/enghong-...3524642601.html )
Water the garden
Ta-dah~

P.S. All these fancy grass will need regular watering. You can experiment with sprinkler systems if too lazy to water manually.
Cow grass is the real 0 maintenance one.
