At this moment, when Yun Feng started to do this, he also understood some of the things involved in this matter.

Formations that incorporate spiritual energy have a greater chance of giving birth to formation spirits. If such an formation were so easy to build, then formation spirits would no longer be legendary existences.

Setting up a formation requires countless materials. Some of these materials have weak life, some are completely material, some belong to metal, some belong to wood, and some belong to earth. It is not easy to integrate spiritual energy into these materials...

You must know that spiritual energy also has attributes. Even some spiritual treasures that are said to have no attributes actually contain a special attribute.

If these spiritual energies are integrated into these materials, then the spiritual attributes in these materials will conflict with each other, and this formation will not be successful...

I'm afraid, the success rate is very slim!

Even if it barely succeeds, its power will be greatly reduced, and it will not save one out of ten, or even one out of a hundred!

However, the spiritual energy refined by the Little Blood Tower is different...

This is truly attributeless!

In the depths of Yun Feng's eyes, rays of light flickered.

He had only discovered the true and pseudo-attributeless spiritual treasures of heaven and earth recently, and it was only after he had compared them with the attributeless spiritual energy in the small blood-colored tower that he discovered this.

This will become his advantage!

Formation Dao... He can study it when he gets to the fairy world!
