There was a large rune array composed of tens of thousands of tadpole-shaped runes on the ground of the sacrificial altar. In the middle of the sacrificial altar, there was a huge cauldron. In the four corners of the sacrificial altar, there were four smaller cauldrons.
Many immortal generals of Yin-Yang Sect looked a bit flurried. However, it was too late. In the blink of an eye, all of them had been fixed onto the bronze pillars. They couldn't even move.
As the huge cauldron in the middle of the sacrificial altar and the smaller cauldrons in the four corners were lit, they gave out over 30 cm high green flame which looked like jack-o'-lanterns. As a result, the immortal generals' pale looks turned green.
"What do you want? I'm the head of Yin-Yang Sect. Just do it to me. Let go all of them!"
