Celestial silk is incredibly flexible. If you stack dozens of layers together, the resulting soft armor can withstand the swords of the Qi Refining Stage.

If you stack hundreds of layers, it can even resist the swords of the Foundation Establishment Stage.

However, if the opponent surpasses the Golden Elixir Stage, the effectiveness of celestial silk armor becomes negligible.

The main advantage is its comfort and high malleability, which is why its price keeps rising.
