Chen Yang saw an introduction to a method of making special soul stones at a glance from one of the pages of the ancient book.
According to ancient books, once an ordinary soul stone is used and its soul power is completely exhausted, the soul stone will break into pieces, so the soul stone is almost non-renewable.
This ancient book was created to artificially create soul stones. The special soul stones mentioned in it are that after exhausting the soul power, the soul stone crystals can still remain intact, and can re-infuse the living soul through a special method.
Enter the special soul stone.
Chen Yang suddenly thought of the brown soul stone in Qiu Tianming's hand and the black soul stone on the ring.
Qiu Tianming used the brown soul stone to replenish the soul power of the bone staff, and then reabsorbed the living soul.
Ancient books recorded the refining methods of special soul stones. Chen Yang continued to read them with great curiosity.
Chen Yang was shocked when he saw that the special soul stone needed to continuously absorb the soul power of other soul stones under the blessing of the seal before it could be used infinitely.
This special soul stone requires the absorption of tens of thousands of high-grade soul stones before it can be successfully refined.
The way to judge success is to observe the color change of the soul stone used for sacrifice.
Ancient books mention that the more ordinary soul stones a special soul stone absorbs, the darker its color will become. The person who created the ancient books stated that the perfect special soul stone should be black.
Seeing this, Chen Yang couldn't help but look down at the black soul stone in his hand, feeling surprised in his heart.
He also discovered that the author of the ancient book later only mentioned that he had refined a brown soul stone and could not continue to change the color depth of the soul stone. The author of the ancient book believed that the limit of refining the soul stone had been reached at this time.
This exactly matches the appearance of the brown soul stone in Qiu Tianming's hand.
Chen Yang couldn't help but pick up the brown soul stone that fell on the ground and looked at it carefully.
The appearance of this brown soul stone is no different from that of an ordinary soul stone, except that the color of the soul stone has changed to dark brown. When he injects spiritual power according to the method recorded in ancient books, he can clearly feel the number of living souls inside.
Because Qiu Tianming was killed by Chen Yang before he could infuse the brown soul stone with a living soul, so there was only half a residual soul in the brown soul stone, and the soul power was pitifully weak.
Chen Yang used the same method to test the black soul stone in his hand, and the result shocked him.
After the bone sword used black sword energy to kill Qiu Tianming, the soul power in the black soul stone was still abundant, and it was almost impossible to detect how many living souls had been absorbed into it.
Chen Yang knew just by feeling that the black sword energy could not exhaust the soul power in the black soul stone even if he used it a hundred times.
"I found a treasure!"
Chen Yang couldn't help but feel overjoyed. Suddenly, he had another strange idea.
Can I still continue to refine my black soul stone?
The recipe for refining the soul stone recorded in the ancient books was relatively simple. Chen Yang couldn't help but hold the brown soul stone in one hand and a ring inlaid with the black soul stone on the other hand, and began to pick out the recipe for refining it.
After a moment, the sound of "Zi" suddenly sounded, and the color of the brown soul stone gradually became lighter. A dark brown light was released from the brown soul stone, and then transferred into the black soul stone.
The whole process lasted less than ten breaths. Chen Yang found that the brown soul stone changed from dark brown to light pink, and finally became completely transparent, and then cracks appeared on the surface.
"Snapped!"
The brown soul stone suddenly shattered and fell to the ground.
Afterwards, Chen Yang took out all the soul stones from the storage bag, followed the same procedure, and transferred the soul power inside to the black soul stones.
