Opalite

Wei Wuxian, grieving over Jiang Cheng's death, devises a brilliant plan to travel back in time, bringing along some of the people who are most important to him. However, he is unaware that by the time he retrieves Jiang Cheng, his brother has already been reincarnated in the modern world and is living a happy life that he doesn't want to leave behind.

Now, faced with the harsh reality of his past, Jiang Cheng has no choice but to relive his former life, albeit begrudgingly.

Fortunately, a benevolent deity takes pity on him and brings his beloved wife from the modern world into this one. The only problem is that she has fallen into the hands of the Wens during the war. Will Jiang Cheng ever discover that his wife is also here? Will he be able to save her while also protecting his family?

PS: This is extremely Jiang Cheng-friendly. There will be no bashing of any character. MXTX has complicated characters, not even her protagonists fall into the black and white pattern. So if you can't handle complex characters and grey morality, stay away.
