The Reborn Prince Was Usurped by His Younger Brother at the Beginning

The male protagonist traveled to the Heng Yue Kingdom. Unexpectedly, it would be possessed by Prince Yong'an, who died of fear in Concubine Chang's arms. Yong'an was a newly crowned prince. Before he could be crowned, he was usurped by the second prince and chased after him. He fled to the fiefdom of Qingyi and heard that the second prince Yongji was going to attack and kill him. So Jiang Qi, the time traveler who calmed down, naturally could not sit still and wait for death. Perhaps it was fate. In desperation, he actually used Liu Yu's Queyue Formation of the Southern Song Dynasty and defeated the 20,000 elite cavalry who were chasing him with 5,000 troops. The time traveler has naturally increased his confidence. Since fate has destined him to be like this, of course he has to fight to regain everything that should belong to him for Yong'an who was scared to death. Jiang Qi used his knowledge to make guns and cannons, visit the poor and ask questions about suffering to win people's hearts, and soon gained a foothold. Yongji refused to give up and united with the Dongyi Kingdom to attack Qingyi, but under Jiang Qi's skillful command, the 300,000 troops of the two countries were defeated. Jiang Qi did not stop but went all out to restore his Hengyue Kingdom...
