Elder Xi might have held a high position in the past, but he chose to distance himself from City A and his influence naturally had dropped. That was how the world turned; no matter how high your glory, the moment you distance yourself from the center of it all, you would be forgotten at the fringes.
The Tong family and Shen family, on the other hand, had stayed in City A. Their grandchildren had grown up and taken root in City A, so their influence had only gotten bigger from before.
In other words, the Xi family was no longer a worthy rival. In fact, the Xi family had declined in their eyes. Therefore, with both the Shen family and Tong family there, the Xi family would have to yield.
Unless the Xi family didn't care about having no political future or wished to continue their decline, they would know what to do.
Madam President saw through Shen Ru's thoughts easily.
