Seeking the name of a martial arts novel

The male lead was called Lin Zi. He was raised by someone else. Later, this person was killed by an assassin organization, and the male lead went to take revenge. This assassin organization was a group of twelve zodiacs. Each of the twelve people had their own characteristics, just like their zodiac. For example, the pig was especially fat, and the monkey was especially thin. Later on, the protagonist learned a set of swordsmanship by chance, called Rainbow Swordsmanship, which was the unique skill of the leader of Beggar's Sect, Yu Piao 'er. There was also a unique skill called Hundred Beasts Fist. There were two eminent monks in it who seemed to be called Master Ku Rong. One was Ku Rong, and the other was Rong. Master Ku was thin, and all the plants around him would wither. Master Rong was fat, and the plants around him were thriving. I read this wuxia novel when I was in primary school.
