Although this is Fang Fang's body, this dantian is actually a small world, any element of the five elements exists, there is gold, wood, earth, water and fire.

And the shining place in the dantian is gradually expanding, and it is no longer just shining. The place was shrouded in light, and even the little tigers couldn't see the location.

In this regard, the six of them and the ten of them didn't make any moves, they just watched quietly, and there was no sound.

These people knew that this was Fang Fang building the sword blood pool, so naturally they couldn't affect Fang Fang.

After starting to build for a while, Fang Fang realized that if he didn't still have a lot of the essence of that sword blood in his body, he might not be able to build that sword blood pool at all.

This sword blood pool was built in the dantian, in addition to constructing the formation in it, it was also supplemented by sword blood and was also used as the base to complete the structure.

As long as this sword blood pool is successfully built in the dantian, it will produce that sword blood on its own. As long as Fang Fang is not extinguished, it will not be destroyed.

Although Fang Fang already knows the process of construction, there are still some risks, and this is not absolutely without risks.

However, for the sake of Jian Yi and their reshaping of their bodies and their new life, this risk is nothing to Fang Fang, it is worth it. In addition, after all, once this sword blood pool is successfully built, the qualifications of the little tigers will definitely be improved in the future, and the probability of them breaking through to the immortal realm will be greatly improved at that time.

Of course, Fang Fang himself will also use sword blood in the future, which in Fang Fang's opinion, is a triple win, and it has a great effect.

And this matter of constructing the formation lasted for more than four hours, and the area of that glittering position already accounted for one percent of Youdantian.

Although the dantian is a part of the human body, it is actually the same as the space of those secret realms outside the sky, but it is just a little smaller.

Therefore, the diameter of that place in the dantian is only about ten meters now.

At this time, the construction formation had been completely completed.

At the same time, Fang Fang immediately began to rest and adjust her state and return to her best state.

Half an hour later, Fang Fang continued to build.

Therefore, the little tigers saw that the shining place in the dantian was no longer expanding, its diameter was about ten meters, and the light shrouded in it was gradually dissipating, and it was getting weaker and weaker.

Then, everyone saw that the place was gradually concave, and when the light completely dissipated, the little tiger and the others saw that the place had become a pool, the color had not changed, it was still the color of the earth, and there was no sword blood there.

And the place was still gradually concave until it reached a depth of about fifty centimeters.

Xiaohu and the others looked at that place so transformed and changed, and they were very fascinated, as if they wanted to understand why this was happening.

In this regard, the sword is also very magical. Although they knew the method of building that sword blood pool, it was the first time they had seen such a situation in the middle of this dantian.

When I saw it for real, I had to be amazed by it, which was really amazing.

Although this has already been built into its shape, this has not yet been completed, Fang Fang still has to construct that formation for this purpose, and at the same time, he must also use the refined sword blood essence to assist in stabilizing it.

And this step is the key to the speed of production, which is also the most complicated step.
