Hu Changshou first observed his surroundings and found traces of people walking past. He decided to follow the traces.
If everything went smoothly, he would only be two or three days late. He would follow the traces and eventually find Xiaolu and meet her.
He had some understanding before. The beasts in the foreign land were more ferocious and bigger than those outside. He was just a little stronger and was not omnipotent, so the best and safest way was to catch up to Su Xiaolu and the others.
In the first two days, Hu Changshou had indeed followed this method.
He kept looking for traces and making marks to prevent himself from getting lost. This way, he would not be lost in the fog before he caught up to Su Xiaolu.
During the day, he would just eat some dry rations. At night, he would find a big tree to climb up.
After ten days, Hu Changshou did not catch up to Su Xiaolu and the others.
