When Zhang Tiezhu was eighteen, he underwent spirit testing, revealing a maximum of six strands of Earth Spirit Root.
His partner had only three strands of Fire Spirit Root.
Now, their offspring are growing normally within the Yan Clan Territory, with spirit roots reaching Middle Grade.
According to the core theory of spirit roots in this world, Zhang Tiezhu's spirit root potential limit at birth should have been around Middle Grade, but being in the Absolute Spirit Land for eighteen years delayed the development of his spirit roots.
In fact, six years ago, Dong Jiangling had already sent a letter, stating that his daughter's spirit roots, after living near the market since childhood, reached eleven strands of Gold Element Spirit Root at the age of fifteen, also achieving Middle Grade.
However, in the cultivation realm, spirit root inheritance also involves mutations and variations, so at that time, Li Ji'an could not confirm his judgment.
