Revitalization of Spiritual Energy from Qi Practitioner to General

A modern Taoist priest died trying to save a child who fell into the water. I thought I could ascend to heaven, but I didn't expect to be transported to a parallel world in 2009 when I opened my eyes. Different from the previous life, this world did not have Taoist priests or scriptures left by the sages, but there were many strange foreign sects introduced. What's even weirder is that the oxygen has increased significantly compared to the previous life. In the words of the previous life, the spiritual energy has revived, and unknown monsters and ghosts are about to appear. This novel and its characters are purely fictitious.
