MTL - Officer Matsuda Wants To Save Himself - Chapter 21

I thought I would live a better life in my second lifetime. Unbelievably, I’ve reincarnated into a slime that rolls around on the ground. Anyway, this is my precious new life, so I must work hard.

As the mad researcher in a tattered white coat activated the self-destruction device, Qin Luo knew that this time, there was no escape.

He was well aware of the destructive power of the self-destruction device.
Even if he is genetically inborn with an independent space, it is impossible to use the power of his space to resolve against such a terrible explosion.

His only end would be a torn space and the crushed bones.

On an unrecognizable earth rampant with zombies and mutant creatures, this end is good.

Death is far better than living…

With a skull splitting headache he opened his eyes to find himself reborn in the year before the apocalypse happened.

Is this a joke!!!
Is this a chance for him to be prepared to combat the apocalypse?
Is God not satisfied with all the bitterness he had went through and would enjoy watching him suffer once more?

Two very different great eras appeared before him:

Abundant dietary protection, developed industrial products, miraculous medicines, and explosive information, this is 2022.

Simple folk customs, rich wild resources, scattered antiques, and treasures of the age, this is 1982.

Traveling between these two eras, Wang Yi didn’t think much of it, he just wanted to live a good life.
