Sun sign, Moon sign, Venus and Mars are all in 12 house, and Uranus and Neptune are both in the eighth house. What will happen?

The sun, the moon, Venus and Mars are all important planets. In 12 house, the name of 12 house is a hidden house. That is to say, it represents the unconscious and subconscious, which is difficult for them to realize. If a person's sun (self), moon (emotion), Venus (values) and Mars (action) are all hidden in the house, it may be difficult for him to express himself. Emotions like to be hidden in his heart, and it is easy to hide himself in action. It doesn't matter if the king of the sea is in the eighth house. It's a generational planet.
