In the urban version, to promote the great trend of Spiritual Energy Revival, Lu Yan once ordered the Underworld ghosts and spirits to secretly construct a Beimang Tomb, intending to use it to alter history and unveil the arrival of Spiritual Energy Revival.
Most of the contents within the Beimang Tomb were fake artifacts forged after being deduced by the Giant Spirit God's Path of Omniscience. Even professional archeologists couldn't detect the problems, and would only regard it as a relic of a lost era of Spiritual Qi.
To increase credibility, Lu Yan left behind a Cultivation Technique in the Beimang Tomb, which was the most common 'Chang Chun Skill' in the xianxia version.
