Blood is the 35th clue. It is a Lucian clue and was located either in the Statue of Liberty or in the Eiffel Tower.
History[]
The Lucian branch gave one of their agents, Gustave Eiffel, 10,000,000 francs so that he could make monuments in order to hide a clue. He used the money to create the Eiffel Tower and the Statue of Liberty. The Lucians hid this clue in a compartment in both of these monuments. Each decade they would move the clue from one monument to the other so that the other branches had a harder time locating the clue. The Tomas developed urban climbing but they still couldn't steal the clue.
Blood[]
Every animal possesses blood inside their body. It helps to pump oxygen through the body. The heart is used to pump blood through the veins. Human blood is initially blue or purple but the second it becomes oxygenated (when a human is injured) it becomes scarlet or red.
