There was indeed an abyssal passage in Ghost Face Valley, and there was a world lock.
After Lu Qing personally descended and retrieved the power of the world lock's origin, he did not have much time left to revive.
At first, he was thinking that if he had the time, he could use the teleportation function to go to the South and fight with the Chu people.
However, there was not enough time. If the Yan and Qi Alliance Army in Wu State wanted to launch an attack on the Chu army, the preparation time needed was not something that could be done in a few hours.
It was not impossible for Lu Qing to temporarily organize a team of elite cultivators and launch a surprise attack with him leading the team. However, he was worried that his resurrection time would end halfway through the battle. That would be too awkward.
He thought about it and decided to forget it.
