MTL - Venerated Venomous Consort - Chapter 12 Is that really a child?

When the spiritual barrier that has been intact for a hundred years is shattered by a meteor, spiritual energy that had disappeared starts to return.The mystical realm slowly begins its revival—magic, witchcraft, curses, supernatural lifeforms, strange and mysterious legends, monsters and gods from other worlds…The old world order collapses, yet the new order is mystifying and chaotic.Just before the unprecedented reformation is here, Tang Qi awakens and finds himself hung on the cross, having turned into an inferior demon and in great pain and agony…With his special ability to see through the nature of all things from the mystical realm and a sly and crafty mind, follow Tang Qi as he develops new skills and powers—as well as making new friends and allies—to battle and protect himself from never before seen supernatural threats in an unfamiliar world!

I originally thought this was a world like an ordinary urban novel…Drawing comics by myself, traveling is pretty good.

Fei Bai discovered through his boyfriend’s trumpet account that he had been wearing a green hat. Not long after the breakup, he recognized the third party in their school coffee shop.

The senior brother is handsome and tall, but it looks like… he’s not a 0.

When Fei Bai thought his ex might be doing zero for love behind his back, he became angry. He decided to take the initiative to seduce this senior brother so that his ex-boyfriend could also experience the taste of wearing a green hat.

The sky’s the limit. Fei Bai successfully seduced the third party. He walked side by side with this senior brother on the campus and bumped head-on unto his ex-boyfriend.

He thought the moment of revenge was coming, but in the next second, he learned that he had flirted with the wrong person. The senior brother beside him was not the mistress but the former president of his father’s company!

Fei Bai originally planned to apologize and run away, but he didn’t expect to be blocked in front of his home the next day.

The man he called senior brother pressed him against the wall and said in a low voice, “You are so good at seducing people. Who would let you go?”

Those who disparage him will fall into despair, but if you're a Climber in a tight scrape, look to the sky and say a little prayer.Maybe he will appear?Odds are probably better if you pay for my drink.- Rumor overheard on a 1st Floor Tavern. Originator did not pay his tab.
