It was just like how Wang Debao's soul from Parallel World was less than a millionth of Zhu Wuyan's soul from Dongyuan Continent. However, once it fused with Zhu Wuyan's soul, it could cause Zhu Wuyan's soul to undergo a huge increase. It could at least double or even multiply.
The doppelganger's soul in Parallel World seemed to have made up for some of the flaws in the main body's soul, making the main body's soul more complete. That was why it could produce such a chemical reaction.
Moreover, after fusing with his own souls from several worlds, Zhu Wuwan could clearly feel that her comprehension had become stronger.
This was also the greatest benefit that the soul of the parallel world had brought to Zhu Wuwan. It far exceeded the benefits in other aspects.
