"The heart of fire is exquisite and transparent, crystal clear and round. I am still one step away from the last step, and I can break through the shackles of the alchemy."

Xu Xuan was repeatedly deducing those steps in his mind.

The crystal heart of the main fire divides a trace of the purest fire essence into the spleen.

Fire produces earth, and the spleen controls earth.

Xu Xuan repeatedly tried the Buddha and felt that the pure fire essence qi penetrated into the spleen and was very smooth. However, if too much fire essence qi was injected, he would still feel uncomfortable.

Trying repeatedly still fails.

If you want to make your body develop a new kind of physical cultivation power out of thin air, it sounds incredible.

Because the essence of physical cultivation is derived from the flesh and blood of the body, it is different from the immortal cultivation and martial cultivation that can integrate external forces.

"The lungs control metal, the liver controls wood, the kidney controls water, the heart controls fire, and the spleen controls earth... The human body is a subtle and infinite universe, and the five internal organs are the five elements hubs, and each internal organ controls the rules of a system."

Xu Xuan was murmuring to himself, and suddenly a flash of inspiration flashed and found a direction faintly.

Although he did not immediately find a way to produce earth, he clarified a way of thinking.

"The reason why I can easily form a heart of fire is because my physical body tends toward it. The second step to the main soil is that I am not good at, but the spleen contains various mysteries in the main soil of the human body. If I can understand and penetrate its rules system, I may have a chance to break through that link..."

Xu Xuan was very excited. While refining weapons and deriving, his thinking became wider and wider.

Grasp the right direction, then all you need is time.
