MTL - Eternal Life - Chapter 1578 pauper

One day he suddenly found himself in hell.
All he had was the desire to live and a predation ability.
From the first to the ninth thousand circles of hell, he absorbed dozens, hundreds of thousands of demons.
Even the seven great dukes of hell bowed down before him.

– Why would you wish to go back? Doesn’t his highness have everything that’s in Hell?
– What do I have?

Nothing to eat, nothing to enjoy!
The only things in Hell are the barren lands and terrible demons!

“I’m going back.”

After ten thousand years he returns to Earth.

Ji Nai-tang paid attention to Cen Muqi for 12 years. This secret love had been hidden in his heart. When he finally couldn’t hide it, he sent himself in front of Cen Muqi, pretending to be a pig to eat the tiger and step by step planning to trap the golden thigh.

Ji Nai-tang: It is not that I look good, it is that you make me look good.

Cen Muqi: It turns out that it is important to have a boyfriend who will take pictures.

Ji Nai-tang: But you are not my boyfriend~

Cen Muqi: Can I apply for it?

Ji Nai-tang: What are you applying for?

Cen Muqi: Applying to be your boyfriend!
