There's Something Wrong with the Chief: Du Zhu You Bing (Novel) Vol. 4

Although Xiahou Lian and Shen Jue have reunited, danger casts a shadow over their lives together. Xiahou Lian hasn’t managed to stamp out Qiye Garden, and under a new leader, that sinister enclave of assassins has become more bold. Xiahou Lian and Shen Jue’s allies have already begun to vanish, die, or turn against them. And making matters worse, the mysterious, debilitating “Paradise Fruit” has grown more and more entrenched in Great Qi. Staving off Qiye Garden and eliminating the Paradise Fruit will require a journey into remote mountains blanketed with snow and riddled with foes. But as Xiahou Lian prepares to depart on the perilous quest, he’s unaware of the lengths Shen Jue will go to in order to keep him within reach.
