Both the Sui officials and Li Mi were apprehensive about the approaching Yuwen Huaji. Yuan and Lu decided that the proper strategy was to seek Li's submission by pardoning him and awarding him high titles, and have him resist Yuwen—with an eye toward eventually turning against Li after he had been worn out. Meanwhile, Li had already engaged Yuwen several times, repeatedly prevailing over Yuwen but unable to definitively defeat him. Therefore, when Yang Tong's messengers arrived, Li seized the opportunity to suggest, making a submission to Yang Tong agreeing to be a Sui official and offering to attack Yuwen. Yang Tong then heaped a number of honors on Li—including creating him the Duke of Wei, now as formal Sui creation, and making him the nominal commander of all Sui forces. However, Wang opposed this rapproachment with Li, remarking that Yuan and Lu were awarding honors on a bandit, drawing suspicions from Yuan and Lu that Wang was intending to surrender the city to Yuwen. The Sui collective leadership thus began to suspect each other.
