After fully absorbing Constant Star Gold, Lu Chen's Constant Star Mass reached 910.
Originally, according to the sum of Lu Chen's 505 and Constant Star Gold's 500, the Constant Star Mass should have been 1005.
However, since Constant Star Gold had been in existence for quite a while, nuclear fusion within the Constant Star Body had already produced some Iron Elements and other elements.
These elements in total added up to more than a hundred Constant Star Mass, and of course, Lu Chen would not absorb them to disrupt his proportion of Hydrogen.
When he previously absorbed Constant Star Silver, although there were other elements within Constant Star Silver Body, their mass was not significant and did not greatly affect, Lu Chen chose to absorb them altogether to save time.
