The Black Gold Twins' alchemy skills were indeed formidable.
Half an hour passed.
Qin Shaofeng still had not gleaned anything when Heizi's shout rang out. "I'm more or less ready. I only need to add one more spiritual herb. Once it's refined, the furnace will explode."
It was clear that Heizi was far too familiar with the process of blowing up a furnace.
Upon hearing him, Zang Feng and the others were all dumbfounded.
Even Wuxin's mouth twitched violently.
"Stabilize the medicinal power first. Wait for Old Jin to finish refining."
After giving the order, Qin Shaofeng continued with what he was doing.
After all, he was merely deep in thought. To the others, it looked more like he was pondering a solution.
Old Jin's refinement was clearly far more difficult than Heizi's.
Just from what Gusu Hanxing and the others could see, Old Jin had used over ten times as many spiritual herbs as Heizi. The ferocious medicinal power emanating from the pill furnace made them tremble with alarm.
More than half an hour passed again.
Only then did Old Jin grunt.
Qin Shaofeng abruptly opened his eyes. He had indeed been contemplating, but he had also been keeping watch over Old Jin's refinement and understood the progress of his alchemy very well.
He could tell that it was not that Old Jin did not want to speak, but that he no longer had the ability to do so.
"Xing'er, Wuxin, take out your defensive treasures. We'll defend ourselves."
Gusu Hanxing had evidently already guessed Qin Shaofeng's intentions. The moment he spoke, she took out a top-grade defensive treasure and shrouded them within it.
Although Wuxin reacted half a beat slower, he quickly took out his defensive item as well.
Zang Feng and the others were all stunned by
