Despite the immense pressure Su Xin had placed on Ning Feng, Ning Feng still chose to make his move.
With a flicker of his body, he tossed the Mustard Seed Bag from his arms directly into Ning Fei's hands, keeping only a blood-red pill for himself.
He swallowed the pill in one gulp. Instantly, he felt his blood and qi begin to burn and boil. Heat poured from his entire body, while a powerful force accompanied that surging blood into his limbs.
This, too, was a secret pill passed down by the Blood Demon Sect. It could burn one's blood and qi in an instant. Unlike actively burning one's blood essence, however, once this pill was consumed, it could not be stopped—and the power it brought was correspondingly greater.
Put simply, this thing was meant for staking one's life. Even if you killed your enemy after swallowing it, you would not survive either.
Though Ning Fei was from a collateral branch, she was still a member of the Ning Family and knew the origins of some of its trump cards.
Seeing Ning Feng swallow that pill, tears immediately streamed down Ning Fei's face as she screamed hoarsely, "No!"
"Go!"
Ning Feng let out an angry roar and drew four short swords, which transformed into four streaks of light as they slashed toward Su Xin.
These four short swords had been forged by the Ning Family in imitation of that previous sword formation. Their grade was even higher than the longswords within that formation, reaching the Mysterious Grade.
However, too few members of the Ning Family were proficient in formations. They had been unable to replicate the formations inscribed within that sword formation, so they gave up after producing just four short swords. Any more, and the sword formation would fail.
