Soul Penetrates the Resistance War, Cultivates Immortals and Violently Tortures the Devils

The moment the bullet grazed my ear, I suddenly understood - soul piercing is not rebirth, but another gun handed to me by fate. The smoke of gunfire and the smell of blood hit my face. I am Leng Feng, a modern special forces soldier and surgeon. When he opened his eyes, he became a little soldier on the front line of the Anti-Japanese War. Before he had time to adapt to this new body, a loud roar of death exploded in his ears. The look in my comrade's eyes when he fell was like a nail piercing my heart: it was not fear, it was despair. The system has arrived, bringing with it the light of cultivating immortality and also bringing choices. Qi training, foundation building, golden elixir... Every level is a test of blood and fire. I used "Wind Step" to dodge bullets on the battlefield, and I also used "Rejuvenation Pill" to revive dying people in the dark night. But this world is not only about Japanese invaders and battlefields, but also about sects of cultivators hidden in the mountains and forests. Some of them collude with the Japanese invaders, and some just want to seize the system from me.
