This series is good and has very Historical and scientific accuracy. The acting is very good specially song ill gook and lee ji hoon that make series very beautiful and cool. The core of story is very good but the series focused too much in margin story. So some times series became boring and out of line and hard to understand the plot. So in compare of emperor of the sea and jumong this series is very weak but I recommend it specially for scince lovers.
