MTL - Magic Chef of Ice and Fire - Chapter 33 Summon Mage Cat (below)

Humanity’s first 8th Class Mage.

Betrayed, he traveled back 30 years into the past.

The story follows Ian Page, archmage and the first man to break through the 6th class, then through the 7th and become the most powerful mage, an 8th class mage.

After a lifetime of war and killing, the continent was finally unified thanks to his efforts. Now, old, his wish is to live the rest of his life in peace and try to find salvation for all the blood he spilled. However, his old friend, maddened by paranoia, couldn’t tolerate someone so powerful, so he betrayed Ian and killed him.

In his last breath, he cast a time magic that allowed him to travel back to when he was a young boy. With all the knowledge he previously had, he decided to do things better so he could end with less regrets.

Three years into Qin Yu's marriage, his wife and in-laws all hated him.

The most fucked-up separation in the world, is that there is a baby in your belly when you break up with someone.

Bo Yu draws on his cigarette, slowly puffing out the smoke, and looks at the little boy lying in bed with deep eyes.

Two years later, he finally comes back.
