Strongest Survival by Otome Game’s Heroine (LN) - Chapter Volume 4 6: Dungeon Exploration Beginning

A few hundred years ago, Earth was affected by a mysterious force from the depths of the universe, triggering the revival of spiritual energy. However, things didn’t turn out as wonderful as humanity had imagined. The spiritual energy carried a strange power that caused the corpses of all living things to rise again, transforming into ghouls. And above these ghouls, even more terrifying beings existed…There were no ancient methods of cultivating immortality, nor any legendary awakenings of supernatural powers. But within the spiritual energy, there was also a presence of ghostly energy. This led to the emergence of Runes.Some people bore mountain runes, enabling them to move mountains and overturn seas, suppressing chaos. Others carried river runes, allowing them to reverse the flow of mighty rivers with a mere gesture. However, this process required a special profession to assist these rune cultivators—to constantly modify and engrave their runes, making them more refined and perfect.This profession came to be known as Rune Engraving.

Qin Mian opened his eyes and found himself lying in a leaky thatched room. The problem was that he was still in his family’s villa beforehand! What’s more, there was another man lying next to his leg in the quilt!

“You, you, who are you?”

The man sat up quietly, his upper body exposed as looked at Qin Mian for a moment before he carried a worn out bowl with a cracked corner from the low table at the head of the bed. The man said in a muffled voice, “Wife, drink water.”

Qin Mian’s eyes rolled backwards and he passed out.

TN:
Title explanation: 勉为其男 [miǎn wéi qí nán] have the same sound as 勉为其难 [miǎn wéi qí nán] which means to do something reluctantly. 勉 [miǎn] is also part of MC’s name: Qin Mian.  Also, 其[qí ] sounds the same as 妻 [qi] means wife. So, there are words plays. Basically, Qin Mian reluctantly becomes someone’s man [wife] after he transmigrated.
