After Emperor Yang of Sui ascended the throne, his brother Yang Liang rebelled in Bingzhou. Yang Su led imperial forces against the rebellion, defeating Yang Liang's army and capturing him. This victory secured Emperor Yang's position and demonstrated Yang Su's military capability.

Emperor Yang ordered the construction of a new eastern capital at Luoyang. Yang Su was appointed as one of the supervisors of the massive project. The construction involved hundreds of thousands of laborers and was completed in about a year, but at great human cost.

Yang Su was appointed Grand Chancellor (Shangshu Ling), the highest civil office in the Sui government. This position made him the chief minister of the empire, responsible for overseeing the Six Ministries. He held this office until his death in 606.

Yang Su died in 606 AD. Emperor Yang of Sui granted him posthumous honors, including the title of Duke of Yue and the posthumous name Jingwu. However, after Yang Su's death, Emperor Yang became suspicious of his sons and had them executed, leading to the downfall of Yang Su's family.
