I Have Failed to Overcome the Tribulation, and My Spiritual Energy Is Only Here to Recover?

[Urban high martial arts + spiritual energy recovery + decisive killing + single female protagonist + academy + ranking list] Lu Changan's soul traveled through the world of cultivation. After five hundred years of cultivation, he returned to Blue Star again due to the failure of overcoming the tribulation. After returning, he found that Blue Star had begun to recover his spiritual energy. At the beginning of the recovery of spiritual energy, cultivation began all over the world, but the cultivation experience was almost blank. Lu Changan relied on the experience and knowledge accumulated in the cultivation world to become the person who knew how to practice best. The techniques that slipped out casually through the fingers have become classics sought after by Da Xia. Half a year later, the spiritual energy recovered to its peak. Monsters began to awaken, the city was shattered, and Daxia faced a life and death crisis. Lu Changan alone can defeat a million troops, relieve China's difficulties, and save the people from water and fire.
