Outside the immortal cave, Thunder walked directly towards the tribulation formation. The place was surrounded by low-level immortal caves and hundreds of cultivators going about their business. A temporary market had even been set up by the cultivators. Everyone was looking for treasures to increase their chances of passing the examination.
Apart from the tens of cultivators that had come from the Spirit World, hundreds of other cultivators had shown as time went by.
When Thunder first saw the place, there was no one else except the cultivators from the lower world. The population has increased by hundreds since then.
