Eater Blade: Grinding in Apocalypse - Chapter 42: THE MASTER OF THE GUILD.

Kusumi Chiharu gets a message one day that he has been selected as a Monster Tamer, and he is prompted to select his first partner. He thinks little of the message until he receives a giant package the following day. He assumes it’s the porn books he ordered, but the huge box ends up containing the unconscious body of a near-naked girl! She’s a ghoul named Zonmi, who intends to fight beside him as his partner.

However, it turns out that other hot girls at his mostly-male high school are also magical entities, and Zonmi may not be the only one who wants to fight by his side!

After receiving his terminal illness diagnosis, Chu Xun could finally let go of everything. The most important thing of being alive is after all, one’s own happiness.

Dumping a jerk, getting back on his retarded colleagues, firing his dumbass boss, staying in a luxurious house, enjoying a feast and bedding a young, energetic and handsome guy—Chu Xun very coolly did what he didn’t dare to do in the past!

All his savings were spent and as he laid down waiting for his death, the doctor apologetically told him, “I’m so sorry, we misdiagnosed.”

“…” Chu Xun felt faint.

He did another checkup and thought, he did feel unwell recently though?

The doctor looked grim.

Chu Xun’s heart skipped a beat. “Don’t tell me it wasn’t a misdiagnosis after all. Am I sick?”

Doctor: “You do not have a terminal illness, but you are… You are pregnant.”

Chu Xun: “???” Ermm, he’s a guy?

And later, the child’s father, that young, energetic and handsome man, who also happened to be a 26-year-old billionaire, Lin Yanchen, appeared and handed out a marriage certificate already signed by him. “I’ll take responsibility. Let’s get married.”

Chu Xun only realised now that his 30-years-late love life, as though blooming blossoms, was flooding in.
