Is This Prince Poisonous?

Xiliang rebelled and raised troops, and his father's blood splattered three feet across the country's gate. The master, Yan Chengxi, was ranked fourth in the world and was famous all over the world. He cut through ten thousand cavalry with one sword from Kaitian and perished on the battlefield. Xiao Muyu, the orphan of Dayan, has mediocre martial arts skills and a very poor swordsmanship. He longs for the vast world, but he has to shoulder the heavy responsibility of restoring the country and lives in a distant temple. The divine fortune teller Wu Suan, who was also his teacher, his father, and his friend, helped each other with his life. He walked the rivers and lakes to act chivalrously, sat in the temple to make foresight, and rode a war horse to fight with swords. If God grants another three hundred years, the righteous path of the world will not change!
