MTL - Martial Mythology - Chapter 7 vortex

Gawain is dead and was transmigrated, but there was a slight problem during the process.
After floating for more than a hundred thousand years on a different continent, he felt that he might need a body to become a complete transmigrator, but he did not expect that…

The wife is first, the country is second, and the husband is of lesser importance.

All of his life was spent riding a war horse and accomplishing meritorious military services. But what was the result? In the end, he was cast aside once he had served his purpose.

Out of selfishness, he had favored his consort and neglected his wife. Ultimately, the one who stood by his side was the wife that he had neglected for 10 years…

After being reborn, Jing Shao decided to repent and turn over a new leaf…

Standing outside the door while holding a pillow, Jing Shao gazed at the sky. He must first mend his relationship with his wife. Jing Shao formed a fist and knocked on the door, “Jun Qing, I know my wrongs, let me in!”
