Yeo Woon-hwi previously lived as the "Blood Demon" after losing his sanity following the death of everyone he loved, eventually meeting his own demise. However, just as he believed his tragic existence had concluded, he heard his child call him "Dad." This event granted him a second chance, reversing time to the specific moment before he lost everything. Now, he is determined to devote his entire being to safeguarding his family. Instead of repeating his past identity as the "Blood Demon," he intends to transform into the "Martial God" to fulfill this new purpose.
