To Become a Demon Through Time Travel, Do You Need to Do Good Deeds Every Day?

Immortal cultivators are orthodox and take saving the common people as their duty, while demon cultivators kill and practice without moral principles and are bloodthirsty. Both worlds perform their own duties. Two outliers have appeared recently. One is Mr. Yun Zhan, a man from the world of immortality. He is handsome and has mastered demonic cultivation skills. The other one is Zhan Yun Daoist idiot from the Demonic Cultivation Realm. He is crazy, does good deeds every day, and never kills. Asked why the two of them were like this? The answer is the same. "I'm just entering the situation with my own body to find out the enemy's training method, so as to plan for the future war between the two realms, which can help us win a great victory!" All cultivators respect righteousness. Yun Zhan/Zhan Yun: "The aliens on both sides are me, and my way is Infernal Affairs!" If you do one good deed every day, you can obtain spiritual treasures of Kung Fu, gain favor, and gain vitality to strengthen your body. During the battle between the immortal and demon camps, Yun Zhan/Zhan Yun were given great trust and became the only survivors after the war. Yun Zhan/Zhan Yun was silent... Who wins?
