Why can't the dark iron sword of Huashan North Peak be pulled out?

1. There is a saying that the sword is sealed by the divine power of Zhenwu Emperor, and only the reincarnation of Zhenwu Emperor can unlock the seal of the sword body. It is said that this reincarnation will appear when the world is in chaos, and most people can't pull it out.

2. Another way of saying it is that the upper part of the sword is just a gimmick, and the bottom is integrally connected. You don't need to use force when you pull it out. The faster the speed, the tighter it will be. There is a similar principle, the more you draw your sword, the tighter it becomes.

There is also a saying that the sword head is a big iron plate with a yellow stone on it, and the bottom of the stone is covered with cement.

However, there is no conclusive official news about the specific reason why the dark iron sword of Huashan North Peak cannot be pulled out.
