To find Ram, it was necessary to traverse the entire Sahara Desert, and the Sahara Desert itself would be the most challenging terrain Spark Squad had ever encountered since their deployment, without exception.
Biliya's entire territory lay within the Sahara Desert, and after that, Gao Yuan and his team needed to cross the entire length of Biliya from north to south before they could choose from one of three routes.
One route was a straight line, passing through Biliya and Sudan, and driving straight into South Sudan, which was the shortest but had the longest desert stretch to traverse.
The western route involved exiting Biliya, heading west into Chad, and traveling south through Chad to reach the grasslands, then turning west to bypass it. The advantage of this route was the relatively higher number of small villages and desert settlements along the way, which made obtaining water much easier.
