And thus he never invaded

That's one theory the alternative theories for him not invading are as follows:

1. ‌The kind of person he was; He only sought revenge against the people who have done wrong to him and Mongolian people i.e Chinese and Afghans.
2. ‌ By the time he reached the banks of indus, Chinese formed a rebellion against Mongolian so to suppress the rebellion he had to return back to China.
