四大天王在唐代的时候，跟21世纪的格局完全不一样。四天王的信仰，集中在北方多闻天王的身上，也称毗沙门天王。北方多闻天王，他是四天王的领班，因为在唐玄宗天宝年间，边关告急，藩邦来包围西凉城，当时军队攻击不上，没办法解围，边关形式十分火急，唐玄宗就请密教里面，唐密的祖师不空三藏法师，持诵仁王经咒加持，修降伏法，于是在被困的这个城的北门，在天中就出现了多闻天王，而且在云雾之间，又现有无量神兵，更为奇特的是出现了一批金色的老鼠，过去冷兵器时代拿刀枪的，最有杀伤力的是弓箭，这些金色的老鼠

The belief of the Four Heavenly Kings, also known as the King of Pishamen, is concentrated on the King of Duowen in the north. In the northern part of China, he was the leader of the four heavenly kings, because during the reign of Emperor Xuanzong Tianbao in the Tang Dynasty, the frontier was in urgent need and Fanbang came to encircle Xiliangcheng. At that time, the army could not attack Xiliangcheng and could not solve the siege. The form of the frontier was very urgent. Emperor Xuanzong asked the Secret Secret Secret Secret Secret Secret Secret Secret Secret Secret Secret Sec Fa, therefore, in the northern gate of the trapped city, there appeared many Kings of Heaven in the sky. Among the clouds and mists, there were infinite martial arts soldiers. What was more peculiar was the emergence of a number of golden mice. In the cold weapons era, the most lethal ones were bows and arrows, which were golden mice.
