Zhang Daoling, Ge Xuan, Xu Jingyang and Handcuffs are four of the four Tianshi. Zhang Daoling is arguably the most famous of the four heavenly teachers. Because his Dojo Dragon and Tiger Mountain is very famous now, many people know him. Zhang Daoling's greatest contribution should be the countless good deeds he has done on earth. Although there is no earth-shattering event, it is also amazing. After all, at that time, there was no chance to become a god by killing a wicked ghost as in ancient times, but Zhang Daoling's.

The legend of Ge Xuan was a figure in the Three Kingdoms period, and later it was related to Ge Hong, saying that he was the ancestor of Ge Hong. Ge Xuan has two hobbies: one is alchemy, and the other is sightseeing. Ge Xuan can be said to have traveled all over the country, and the most famous elixir cultivated by Ge Xuan in the record is Jiuzhuan elixir, which is also the reason why Ge Xuan can soar in the daytime. Later, he wrote many books, such as the Letters Patent of Lingbao, which was written by Ge Xuan.

Xu Jingyang was originally named Xu Xun. He is different from the first two Shi Tian. Xu Jingyang is not a fairy, but an official. Xu Jingyang lived in the Jin Dynasty and was a very wise princess at that time. Because of his treatment, he was called Xu Jingyang. At the same time, Xu Jingyang saved many people because of his brilliant medical skills. In addition, his excellent quality was seen by heaven, so he soared to one of the four Shi Tian during the day.

Handcudgel is as proficient in medical practice as Shi Tian before, but he made a mistake when he was young. Because the dose was not well controlled, the handcuffs caused casualties to the patients, so I began to re-examine my medical skills and didn't want to do it again. It was not until later that he came into contact with Taoism. With the help of Taoism, it has never happened before. As the Daoism of Handcuffs became more and more refined and profound, it also soared during the day, and it is now recognized.
