The moment I finished speaking, the blood-red ritual altar before us began to crack with a series of "crack, crack, crack" sounds. Spiderweb-like fissures appeared all over it.
As the cracks spread, waves of bizarre energy surged out.
Zhang Yuchen and I retreated several steps in a row, backing all the way to the doorway. Neither of us dared let our guard down.
"The ritual altar is about to collapse!"
"Yeah, be careful. The evil energy is too strong. Fall back first."
I spoke in a low voice.
As soon as I finished speaking, there was a loud bang, and the entire ritual altar exploded.
Stone fragments scattered everywhere as green evil energy filled the room. We had not even begun retreating when the sudden change came too fast.
But as that evil energy emerged, green ghost fire spontaneously ignited out of thin air.
The ghost fire hummed as it spread toward Zhang Yuchen and me along the green evil energy.
"Run!"
This ghost fire was far too powerful. Though it did not feel scorching hot, it carried an extreme, bone-chilling cold.
It had once burned my ankle, and I knew how dangerous it was. It burned the soul directly, yet had no effect on flesh and blood.
At my shout, Zhang Yuchen turned and ran outside. I immediately opened the Black Umbrella and held it behind us.
We quickly retreated, rushing straight out of the secret chamber...
But the ghost fire came too fast. We could not outrun it at all.
Seeing the green phosphorus fire surging toward us along with the green evil energy, I shouted:
"Get down!"
Zhang Yuchen also saw the fierce green phosphorus fire. We had never seen phosphorus fire so violent and massive before. Not even in the Tube Building had we encountered anything
