Si Lingtian needs to start grooming Si Yuchen as the successor of their Si Family.
Perhaps Si Lingtian's decision is a bit late, but no matter how late it is, he believes it won't affect them.
Si Lingtian firmly believes that the Si Family is impossible to fail.
Under his generation, the Si Family will absolutely not be destroyed, as long as he believes in this conviction, then there is nothing he cannot achieve.
As for Si Yuchen, he doesn't want to be the one Si Lingtian cultivates. Furthermore, what interests him, Si Lingtian should be well aware.
Si Lingtian still doesn't want to accept that Si Yuchen is not suited to be the next Family Head of the Si Family, because he feels that although the temperaments of his two grandsons are different, they are both descendants of the Si Family.
