What storylines from the manga were deleted from the third season of the "Attack on Titan" anime?

The third season of the animation is missing many key plots. Let me tell you, the first one is about Historia becoming the queen. In the animation, the queen agreed immediately, but In the comics, there are twists and turns.

Historia was hesitant about this matter. At this time, the soldier held her head and said: "There is no time to waste, tell me the answer quickly!" She only agreed to this matter under coercion, which is why the Queen later took it out on Levi.

In addition, there is also the specific content of Eren’s hardening experiment. Although the hardening experiment is also described in the animation, the animation only gives one result, that is Eren. After completing the hardening experiment, he was in a panic. In fact, the whole thing was very complicated. Allen did three experiments in one go. At the beginning, Allen turned into a 15-meter-tall giant. At this time, Allen's thinking was clear, but he Still didn't know how to harden it, so Allen turned back into a human and started the second experiment. He could only turn into a 13-meter-tall giant, and his ideas began to get confused. What appeared in the animation was actually the third transformed giant. At this time, Eren's giant is only about 10 meters long. This tells us the limit of Eren's giant power, but the animation was deleted.

In addition, Xiao Xiao's wonderful lines are gone, "Purification of the nation in 1700 years? If that were the case, not even a hair of the Marais would be left. The ancestor Ymir used The power of giants only brings wealth? That is also far from the human nature I know."

This sentence is very important, it tells us that there are problems with the history of Marais and the wall. , however it was deleted from the animation.
