The Secret of the Ten Great Weapons

From 304 AD to 439 AD, these more than one hundred years were the period of the Five Hus and Sixteen Kingdoms, the darkest and chaotic era in history, with wars, famines, and plagues going hand in hand. However, when you were born in troubled times, a hero would appear. He created a pavilion named Tianji, and later generations respectfully called him Master Tianji. He was born in these troubled times, acted chivalrously, saved people from fire and water, and saved the nation from troubled times. The weapon he used was called Tianji Box.
