The seventieth bolt of thunder.
A violet streak of lightning crashed down with ice-cold callousness. The black-robed Ji Ning beneath it pointed with his finger, causing the golden sword of the [Greater Thousand Swords Formation] to once more soar into the skies.
Rumble…
It once more blocked the assault.
"I hope it is merely eight nine-sets. If it grows much stronger…it may put too much stress on my heartforce." Ning was a bit worried as well. Third-level heartforce was very powerful, and it would be easy to use it against eight nine-sets, but if it became the full nine nine-sets…the power of the thunder would skyrocket to a new level. By then, each blow would most likely require Ning to use up quite a bit of his heartforce. Once it was used up, he would definitely perish.
