On one hand, Ves has alot to gain from Poly's plan being enacted. The GSA is sure to be among those allowed to field warship, and his personal value to Red Humanity will skyrocket after he gives his presentation! Case in point, her 'batch human' idea would mesh perfectly with his Carmine System!! Also, his Companion Spirits would allow anyone to benefit from two Cultivation Methods simultaneously!! But on the other hand, as the saying goes, "Absolute power corrupts absolutely".
putting more thought into it, of the 3, the xenotechnicians plan is the least realistic as in the past the reason humanity managed to surpass the aliens was because they were underestimated but here the natives of the red ocean know full well how strong humans can be and they also have a similar race in the puelmers that steal tech too so they definitely would never give humanity the chance to make a comeback if they chose to bend the knee...Ves has a lot of personal experience to condemn the cosmopolitans rosy view on cooperation with aliens as the Larkinson family was treated as disposable guard dogs despite being one of the founding family's of bright republic
