"Have you forgotten, Tobirama? Yanbai put you through a year of education in a single second. Yanbai said you two were like twins. Whatever she could think of, you could think of too. Sooner or later, you would touch upon these taboos."
Madara Uchiha said expressionlessly, "But since what you want is Yanbai's blood, the techniques at the beginning of this scroll certainly won't satisfy you. To understand the concepts described in the material that follows, you'll need the biology and chemistry Yanbai taught you in the illusion space."
As he spoke, Madara Uchiha's manifested form gradually broke apart into a humanoid mixture of thorns and blood-red roses, then slowly sank down, leaving only a final warning.
"Take what you came for and leave. Don't send anyone else to disturb Yanbai's eternal rest. Otherwise, no matter how many come, I won't show mercy. Next time... I'll kill them outright."
Holding the scroll, Tobirama Senju silently watched the thorns withdraw. He could not help wondering, Was Madara's real body as young as that clone just now?
But Tobirama Senju did not move. He was still far from Konoha Shinobi Village.
Tobirama Senju could not bear to wait until he returned to the Hokage Office. He had to finish reading the rest of the scroll now.
Even though the chance of being attacked and losing the scroll was slim, Tobirama Senju still worried that some absurd twist might occur on his way back. He had to read it now. Right now!
After Madara Uchiha left, the surroundings grew even darker.
Tobirama Senju took out several Artificial Night Pearls. Kneeling on one knee, he continued reading the material in his hands.
What followed, however, left Tobirama Senju deeply shocked.
