This is just my personal understanding, let’s discuss it.

From the perspective of the supplementary plot, it mainly involves the following parts:

1 The origin of the prototype of the doll in the Hunter’s Dream: senior sister Maria, and the old hunter Gorman. The ambiguous relationship between teacher and lover.

2 The source of Spider Rom’s godhead: it was dissected by the orphan Koth on the beach.

The newly added and improved content is:

The first generation of hunters once discovered Kosi on the beach by chance. There are two possibilities when Kosi was discovered and Kosi was still alive, and the hunters killed him. He killed Kosi and took away the orphan of Kosi. The other is to find Koth's body on the beach and take away the Koth orphan inside the body.

In the Watchtower, the church vivisected the Kosi orphan and learned more secrets. This act angered Koth, who cursed all hunters who were addicted to killing. In the end, these hunters cannot escape and are drawn into the killing dream, where they will kill each other forever.

In addition, the hunters may have massacred the fishing village while attacking Koth.

The understanding of the new characters includes:

1 Ludwig: The most powerful among the first-generation hunters, it is very likely that he was the fatal blow to Koth. , so he suffered the heaviest curse and was deprived of his human form and went crazy to the end.

2 Senior sister Maria: Maria may be a descendant of the blood clan. After participating in the tragedy in the fishing village, Maria was completely disappointed with the hunters, which was also the moment when she and Geman parted ways. She stayed in the tower to care for the sick, but saw even more cruel experiments. Many netizens said that Maria might have committed suicide when the experiment was successful (the result of the deification of Spider Rom). But due to the vampire's genes, he cannot die. These are often based on close observations of Maria before the battle. Blood stains were found on his chest and wrists. One hand hangs down, looking like a slit wrist. Ultimately guarding the secret of the fishing village.

3 Assassins and other hunters in the prison: After killing Ludwig, you will pass by a prison. In addition to the assassin hunters, there are also a group of black-robed hunters imprisoned. Although these hunters have average combat power, But all kinds of weird weapons are commonly used. I personally speculate that these may be hunters who have participated in massacres but have lost faith in the church as a result. (Including Assassins) They will obey the Church, but refuse to kill. So the church can only lock them here to keep it a secret. The assassin hunter is very likely to be one of them, and he has extraordinary abilities. He won't join in the killing, but the Assassin Hunter will take action if anyone tries to uncover the secrets.

What remains unclear in the end is whether the organization that gathered the hunters to attack was the Healing Church or Bayer Watkins College? I personally think that the academy has gathered the first generation of hunters, because only the prestige of Master William can make so many old hunters act together. Later, Lawrence performed the dissection of the orphan, (reflected from the surgical statue in the tower). This is also a key point in the split between Master William and Lawrence. Lawrence believes that the research direction should change from eyes to blood, while Master William may have discovered something from the deified spider and his own researchers. After Lawrence ran away, he established the Healing Church. As the church grew, things eventually became unmanageable. Master William could only use Spider Rom to lock the Blood Moon.
