Just like the Human Race joining the Dragon Race as a faction, all human players can only join the Dragon Race and cannot join the Sea Snake Race, which is considered a binding.
The advantage of this is that if the Dragon Race beats the Sea Snake Race and reunifies the Qingcang Sea in the future, as an important allied race, they can request the Dragon Race's assistance in wars with other civilizations, as long as the opponent is not from the same allied race.
For example, if the Celestial Eye People go to war with other civilizations in the future, as long as the opponents are not humans or Merfolk from the Dragon Race alliance, they can request a large number of naval forces and experts from the Dragon Race for support.
So this is not a personal affair at all, but a major event for the entire civilization. Destroying the alliance would make one a criminal of civilization, a consequence most cannot bear.
