Lu Li had asked many to search for Bodhi Fruit and even asked the Du Family to offer some assistance. Lu Ling had been looking for it as well. The Samsara Palace was the most powerful force in the Central Plains and controlled a large chamber of commerce that was the Sanctuary, it was not difficult for them to know that Lu Li was looking for the Bodhi Fruit.
They might not know why Lu Li and Lu Ling was looking for Bodhi Fruit or learn that the fruit could cure Immortal's Perish, but the Samsara Place did take note of this matter. They would acquire the Bodhi Fruit as soon as it appeared in the Central Plains and they would not give Lu Li any chance.
Samsara Palace even told the Hades Society and the Pavilion of Blossoms about this and let them keep an eye on Bodhi Fruit as well so as to buy any Bodhi Fruit as soon as it appeared.
