"Sword Energy Domain, and an extraordinarily high level of control at that, how could this old man possibly!"
The Grey Robed Man, witnessing this scene and feeling the terrifying aura coming from the elder doctor, revealed a look of fear in his eyes.
He finally understood why the Plague Gourd had been continuously sending out warnings.
This old man was actually this terrifying, having comprehended the legendary innate domain, and it was the Sword Dao domain known for its strong offensive power.
In his shock, the Grey Robed Man's thoughts raced, and he immediately conjured a large amount of Grey Energy from the gourd on his back, enveloping himself within it.
Boom!
No sooner had the Grey Energy enveloped the Grey Robed Man than the elder doctor's attack arrived.
Carrying the power of the Domain, the Sword Qi Tide surged and bombarded him vehemently.
However, the Grey Energy outside the Grey Robed Man's body was incredibly tough and did not break immediately.
