Su Xin has only practiced the secret method of "Swallowing Yuan" to the third level, and has not practiced the fourth level.

At the fourth level, you can forcibly deprive and devour other people's souls, thereby increasing the strength of your own soul. However, in Su Xin's view, firstly, this method is too vicious and evil, and secondly, the soul power that can be forcibly taken away from others, although it will go through the secret method,

Transformation may still have a relatively large impact on itself.

It can even directly affect your own heart.

The soul line is only one of the four major systems he cultivates, and it is not his main line. There is no need for him to take such a big risk in order to improve his soul power.

Under the operation of the secret method of "Swallowing Yuan", Su Xin has begun to slowly absorb the soul source power left by the Emperor Tribulation God King.

Long before, he had used the secret method of "Swallowing Yuan" to transform and absorb the soul origin of the Emperor Tribulation God King once. That time, he only absorbed 30%, but it still allowed him to directly upgrade from the thirteenth level of "Void God"

Reached the fourteenth level.

But now as Su Xin continues to absorb, his soul power begins to increase at a terrifying speed again.

Not long after, he could clearly feel that his soul power had risen to a new level.

With the operation of the secret method of "Void God", he easily refined the fifteenth level of "Void God".
