Under Anna's suspicious gre, Kimimaro calmly sipped his milk and soon opened his mouth, "Amber Lead..."

  His first words was compelled a confusion on Anna and Smith face. Soon Kimimaro continued, "Thats the cause you're looking for doctor..."

  Smith recalled on his earlier words, he said that as a doctor, the Death mark was an effect and the cause was unknown.

  He hasn't dabled too much on the death mark before he met Kimimaro, but after meeting the tter, his thought was lingering ln the mystery surrounding the death mark!

  Anna immediately interrupts, "Wait! You said Amber lead? isn't it nonsense? Flevance had been minIng on those ore since 78 years ago, i'm sorry, but it doesn't make any sense to me. If what you're saying was true, then by that logic, Flevance should cease to exist much earlier!"

  Smith looked at his wife cool interruption while Kimimaro calmly sips on his milk, instead of expining, Kimimaro asked,

  "Doctor, see those data once more. Tell us which occupation leading the highest death toll until now."

  Smith had small doubt, after seeing his wife doesn't have an objection, Smith scrounging the papers once again.

  "From 20 years ago until now, the highest death toll was on the miner! and the second was women!" Smith looked at his wife feeling dread, however, Anna spoke calmly,

  "Miner was always a dangerous work to begin with, as for woman? they went to bor!"

  Kimimaro nodded, "Then, tell us once again doctor, how many percentage the miner cause of death was by accident and woman by bor?"

  Listening to Kimimaro, Dr.Smith immediately calcute the numbers, soon he excimed, "Only 10% due to working hazzard! and 2% from bor! Anna!"

  Smith immediately hold Anna's hand feeling extremely worried, the calcution showed that woman had much more susceptibility compared to man!

  Anna was also stunned, she held Smith's hand as she felt cold all of sudden, however, Anna being Anna kept her sharp gaze toward Kimimaro, waiting for the truth!

  Kimimaro doesn't disappoint, he began to narrate, "...Ever since its discovery, Amber lead had always become Flevance cornerstone of civilization, its economical value lead the prosperity of Flevance, as..."

  "...Like the saying, high risk high return. If left unearthed, Amber lead will not cause any problem even if its affecting the environment like water, dirt, tree, flower. even if those were consumed by human or animal, there will be no consequences..."

  "...The problem showed itself when human started to handle it directly! direct exposure within prolonged time frame with Amber Lead will affect the living being, it seeps through your skin and inhaled slowly over time..."

  "...Dr.Smith, as medical personel, you must've been aware that Human body is capable removing the poison from it system right?"

  Smith nodded, "Yes, every living being have that function."

  "What if the poison had accumute so much that your body couldn't remove it in time?"

  "We fell ill..." Answered Smith softly.

  "Wait, wait, i'm sorry. If Amber lead was poisonous, why the effect only showed up now?" Anna rexed her vigince as she felt that Kimimaro actually doesn't harbor any ill intention towards her family.

  Kimimaro chuckled, "Mrs.Trafalgar, poison substances are various in kind, there are fast acting poison and slow acting poison, and unfortunately, Amber Lead poison is in the ter category, even worse. It actually carried down to your descendant!"

  Smith nodded, agreeing to Kimimaro's expnation.

  "How could it be?!" Anna widen her eyes in disbelief.

  Kimimaro looked at Smith as he expined, "...When the baby was still inside the womb, it needs nutrients for it to live. And the only nutrients it could get is from their mother. Unfortunately, Flevance woman who had been deeply poisoned by Amber lead, inadvertently passed not only oxygen and nutritions, but the poison as well."

  Smith stood up in disbelief, he thought that death mark was something coming from the Flevanese genealogy! As the descendants upon descendants of Flevance carried the same mark throughout the generation!

  He never thought that the cause of Flevance generation death mark was from the poison of Amber lead!
