The treasure bank contained all the wealth that Zhang Tie plundered from the 18 Three-eye Association clans in Waii Subcontinent, which were robbed by the latter from the northern countries in Waii Subcontinent.
Zhang Tie didn't feel like counting the value of the gold and silver in the treasure bank. He had been numb about them. The largest region of the treasure bank was used to store these gold. There were over 300,000 tons of silver, all of which were put in the underground warehouse as they were less valuable than gold.
