If one were to observe the tribesmen closely, one would notice a unique phenomenon. There were very few children among them.
The reason for this was simply because the blood of soul-gnawing beasts was too little. Unless they obtained a special birth permit, the terobo people would never raise offspring.
A child born without a special permit would not be qualified to store soul data. After a few decades, the family would have to face the pain of separation.
Someone had once suggested using genetic technology to create soul-gnawing beasts to ensure that the terruans had a sufficient population.
However, after countless attempts, he had never succeeded. In the end, he could only leave it at that.
The soul-gnawing beasts had a unique talent and were extremely rare. After the tribesmen created the land of souls, they had never given up on their search for the soul-gnawing beasts, but to no avail.
