Soul masters in Douro need to absorb some strength at each stage before they can continue to practice. The power that can be absorbed is the soul ring produced after the death of the soul beast, and the soul, soul bone and artificial soul provided by the voluntary fusion of the soul beast.

Extended data

In the world of Douluo continent, there are ten types of soul masters, namely, storm system, sensitive attack system, control system, defense system, treatment system, auxiliary system, food system, summoning system, strength system and remote attack system. Witch spirits can assist people's daily life, and people with special talents can practice and fight with them.

In the works, although there is only a different division of labor, there is no distinction between high and low. But where there are people, there are rivers and lakes. "Everyone is equal" is usually just a slogan. Like ordinary people, the world of soul masters is full of contempt chains.

For example, the storm department always thinks that it is the first. The control department thinks it is the first, and the storm is the second. Sensitive attack means that storm comes first, self comes second and control comes third. The Ministry of Defense thinks that the auxiliary department is at the bottom, and the auxiliary department thinks that the food is the worst.
