由历史人物唐高祖李渊第三子李玄霸演义而来，但完全背离史实。他是隋唐第一条好汉，“年方十二岁，生得尖嘴缩腮，一头黄毛促在中间。戴一顶乌金冠，面如病鬼；骨瘦如柴，力大无穷。两臂有四象不过之勇，捻铁如泥，胜过汉时项羽。一餐斗米，食肉十斤。用两柄铁锤，四百斤一个，两柄共有八百斤，如缸大一般。坐一骑万里云，天下无敌。”在当时几乎没有人能在李元霸马前走上三个回合，可以说赵王李元霸打遍天下无敌手。四明山李元霸击败反王二十三万大军；先后杀死名将伍天锡、宇文成都，在紫金山面对一百多万军队，一对金锤如拍苍蝇般，只打得尸山血海，迫使李密交出玉玺，反王献上降表。
他不知道，这样的局面还能够维持多久，他还能够和项羽拼多久？不想被别人利用，可事实上一直是在为他人做嫁衣……范文轲离开临淄之后，便接到田荣返回的消息。

When they returned to their residence after dinner, everyone talked happily about the feelings of the day. Now they were exhausted, so they took an early rest so as to have good energy to welcome the activities of the next day. We got up at 6 o'clock and went to the second stop after breakfast. For some reason, perhaps without the support of the leaders, we stayed here for more than ten minutes and handed out some leaflets. The teacher decided to divide the troops into two routes: one to Yuanqu Village and the other to Guxin Village in Guxin Town. The driver left the first group in Yuanqu Village on the way, and our second group continued to go to Guxin Village. As it was launched yesterday, we all had experience and completed the task smoothly. When the two groups arrived together, it was already over 11 o'clock, and we took a bus to the school. After a night's rest, I also got up early on the third day and took a bus to Shenze County, Shijiazhuang City. This time it was also divided into two routes. The first group went to Greater Jia Cun and our second group went to Southwest Liucun. After obtaining the consent of the local leaders and the understanding and support of the masses, we carried out the activities. Everyone had the experience of the previous two days and was already quite skilled in the publicity and investigation work, so they completed the task smoothly.
