When the Great Elder suggested that the Heaven and Earth Swap Pill be kept by the Heavenly Medicine Palace, Wu Qun shook his head with a bitter smile...

The Great Elder, hearing Wu Qun's words, also shook his head helplessly. How could someone as astute as the Great Elder not realize that even with the Grand Sky Holy Land's help, keeping the Heaven and Earth Swap Pill could still bring endless trouble to the Heavenly Medicine Palace?

To put it simply...

The Heaven and Earth Swap Pill is only absolutely safe if it belongs to the Grand Sky Holy Land, because their power can suppress any malicious intent towards it.
