Is “In the Romance, the specific division of labor in killing Sun Chen differs from the official history.” true?

When Sun Xiu plotted to kill Sun Chen, the official history Records of the Three Kingdoms, Book of Wu, Biographies of Cheng, Huang, Han, Jiang, Zhou, Chen, Dong, Gan, Ling, Xu, Pan, Ding, records that at the La festival, 'Feng and Zhang Bu signaled the attendants to execute him,' indicating Ding Feng directly participated in the on-the-spot killing. However, in Romance of the Three Kingdoms, Chapter 113, it is changed to Ding Feng arranging 'Zhang Bu as an internal ally,' and at the meeting, Zhang Bu led people into the hall to seize Sun Chen and 'dragged Sun Chen down the hall to the east and beheaded him,' without mentioning Ding Feng acting on the spot.
