This entire Palace was the old man's territory. Although the rules were not set by him, he could influence them to a great extent.
Li Tian couldn't fight back, unless he had the strength to break the rules.
Li Tian had no choice but to admit that he was unlucky. He glanced at the stone platforms at the outermost ring and finally picked a spirit herb that he could use.
"Wait, the restrictions here don't seem to be as scary as I thought. Can I try to break them?" As soon as he put away the spirit herbs, an idea flashed through Li Tian's mind.
After that, he swept a few glances with a guilty conscience, then released his divine sense to search the surroundings. After making sure that the old man's remnant soul was not in the rear hall, he began to sense the restrictions around him.
