A cripple in medieval world (Rewritten version)

This is the rewritten version of the original book "A cripple in medieval world". For some personal reasons I'm publishing it using a different account. In this version, I'm hoping that I can create a work deeper in character development and can bring more excitement to my readers.
A notice will be given in the original novel so I will not be accused of plargism =.=

English is not my mother tongue, so I welcome any constructive opinions that can help me to improve the quality of my novels.
Enjoy.
