Even though Su Xin was under immense pressure from Ning Feng, Ning Feng still chose to make his move.
As his body moved, he threw the bag of mustard seeds he had been holding into Ning Fei's hands, leaving himself with only a blood-red Elixir.
He swallowed the Elixir in one gulp and instantly felt his own energy and blood boiling within him. His whole body was seeping heat, but a strong power was also surging into him as his blood frothed.
This was also a secret legacy Elixir of the Blood Demon Sect. It could burn one's energy and blood in an instant. Unlike actively burning the Essence and Blood, this Elixir couldn't be interrupted once consumed, and the power it brought was much stronger as a result.
In simple terms, this was a tool for desperate struggles. Once you consumed this Elixir, even if you could kill the enemy, you would not survive either.
