To Ye Xiwen, the existence of the Yin-Yang Life-Death Diagram was like a ticking time bomb, one that might suddenly explode at any moment.
As for its benefits, perhaps there would be some in the future, but none could be seen in the short term.
Each of these Ancient characters had likely been condensed from a great expert's lifetime of martial experience and understanding, containing immense power. Though they were called pseudo-Dao Script, how many people had truly seen actual Dao Script? Those were characters that Heaven and Earth could only spontaneously produce under extreme circumstances.
To most people, these were genuine Dao Script. Even for a colossal entity like the Ye Family, the Dao Script preserved within the family could not be numerous.
Otherwise, Ye Qiong and Teng Tongtian would never have fought each other to the death over that "Dou" character, only barely making it out when the treasure vault was about to close.
With one careless mistake, they might have been locked inside forever, unable to escape.
Among the characters collected by the Ye Family was a Seal character. When it came to sealing, no other character was more formidable than this Seal character. Ye Xiwen usually used the Martial character and the Dou character to suppress the Demon Seed and the Yin-Yang Life-Death Diagram, but their effects were far from ideal.
It could be said that he was expending twice the effort for half the result!
Ye Xiwen could more or less imagine how much effort and what price Ye Zhentian had needed to pay to obtain this Seal character for him, so he was deeply grateful. Though Ye Zhentian rarely came to guide his cultivation, Ye Xiwen could ask him whenever he had questions, and Ye Zhentian took great care of him in every respect.
