Heroes in Sui and Tang Dynasties

Li Jiancheng, a game otaku who just eats and waits for death, is playing a game called "Heroes of Sui and Tang Dynasties XX", but accidentally travels to the Hero Continent that is very similar to the game world, and becomes Li Jiancheng, the eldest son of the Li family in Chang'an City. The two younger brothers Shimin and Xuanba are both unique genius heroes, so powerful that the eldest brother Li Jiancheng feels a lot of pressure. Fortunately, with the alchemy talent and a rune hero sword brought in the game, Li Jiancheng became leisurely and at ease.
