After all, if someone else finds out that Ye Tianfan possesses the Heaven and Earth's Ultimate Treasure, they might act directly outside the walls.
At that time, not only Ye Tianfan will have trouble, but everyone will also be in trouble.
After all, there will always be fools, and in the worst case, if someone is reckless enough to cause trouble for Ye Tianfan, everyone outside the walls will have to pay for this fool.
Although such situations are extremely rare, the Real Person of Taichu does not want this rare possibility to become inevitable.
After all, as long as there is a possibility, no matter how small, it can happen, and to make this already minuscule chance even smaller, the issue must be addressed at its source.
The way the Real Person of Taichu resolved this issue was by making the Magical Treasure in Ye Tianfan's possession become a Supreme Magical Treasure, and not the Treasure of Heaven and Earth.
