Shen Luo controlled the heavenly soldiers and looked towards the central area of the cave, and his heart was shocked.
I saw that there were more than a dozen pools of different sizes dug on the ground in the center of the cave. They were filled with blood-red liquid, with many bubbles bubbling out of them and a strong bloody smell. It was actually fresh blood.
Next to each blood pool, there are more than a dozen dark red pillars, engraved with runes, which seem to be a magic circle.
The distribution of these blood pools also has a regular pattern. More than a dozen blood pools form a formation. The magic arrays around the blood pools are also formed into a whole, and more than a dozen small magic arrays form a large magic array.
Countless dark red runes flickered, and the magic circle was also humming. The blood in the blood pool surged, emitting an endless bloody smell.
In addition to the bloody smell in the blood pool, there is also a powerful demonic energy, the two are mixed together.
Several monsters are soaked in each blood pool. The aura of these monsters is very powerful. Most of them are above the Mahayana stage, and they absorb the blood and demonic energy in the pool.
In the largest blood pool, there were two tall monsters sitting. One was a black tiger monster with a human body and a tiger head, muscular body, and a golden "king" pattern on its forehead.
The other one was a huge monster with a human body and an eagle head, it was the same eagle monster as before.
Both of these monsters exude a demonic aura of the true immortal level, which is not inferior to Shen Luo himself.
However, what Shen Luo was most concerned about was a purple-black stone placed in the center of the dozen or so blood pools. The stone emitted a bright purple light and looked like an extremely precious treasure.
A purple sphere was floating above the purple-black stone, and inside it was a vague figure sitting cross-legged, but the figure's shape and appearance could not be seen clearly.
Strands of blood light followed the array patterns on the ground, gathered from the blood pools in the array, first entered the purple-black stone, and then emerged from the other end of the purple-black stone. The blood light became extremely pure and was then injected into the purple sphere.
Blood-colored talismans appeared on the surface of the purple sphere, shining brightly, as if absorbing the blood.
The aura of the figure inside the purple sphere was unpredictable, and Shen Luo was unable to sense its size. This situation had only been experienced by some powerful beings who had surpassed the True Immortal stage.
"Could there be a powerful person in the Taiyi realm inside?" Shen Luo was shocked. He took a look and immediately looked away to avoid being noticed by the other party.
At the same time, he controlled the heavenly soldiers to merge into the nearby soil and conceal his own breath.
The blood formation in the cave was operating, and the blood in the blood pools in various places was rapidly decreasing, and soon more than half was consumed, while the aura of the monsters in the blood pools was generally strengthened.
"What kind of method is this that can allow people to improve their strength so quickly?" Shen Luo sensed this scene and was secretly amazed.
"Your Excellency, the blood pool has run out of essence again. Recently, according to your instructions, all the demon soldiers have stayed in the Black Wolf Mountain and have not gone out to capture blood food. Now there is not much blood in reserve. It seems that the refining of the Blood Soul Yuan Banner has to be slowed down." The black tiger demon stood up and walked in front of the purple sphere, bowed and said.
"No, there is not enough blood food. Then capture some of your soldiers. The Blood and Soul Yuan Banner is related to whether Lord Chi You can escape from trouble completely. The refining must not be slowed down!" A cold voice came from the purple sphere, saying lightly.
