MTL - The Most Powerful BOSS In the Heavens - Chapter 778v3 Killing Bureau (7000 words, please subscribe)

On their first encounter, the 5-year-old Tang Junhe regarded the 6-year-old Yang Xuan as a hero and willingly followed his example.

Yang Xuan: “There are 12 ways to fold a paper airplane, don’t you know? I’ll teach you.”

Ten years later, the 17-year-old Tang Junhe is living in Yang Xuan’s home as his younger brother and the feud between the older generations has yet to subside, as the two teenagers engage in a skirmish.

“The one who falls first would always lose. I knew it but I was happy.”

After ten years, the 28-year-old Tang Junhe and 29-year-old Yang Xuan are unexpectedly reunited. Is it a matter of whether things are different or whether the circumstances stay the same? Two people in the same darkness, neither one can be the light of the other.

Then let’s go together and find light together.

“The prince rides a white horse
The moon is gone
And how silly cats were, always chasing after their tails
The childhood memories are priceless.”

Getting transmigrated inside a novel is not really a bad thing—you know the story, you have the power of the future in your hand, you know all the hidden keys. You might as well end up as the most powerful and omniscient being in that world.That is, if you don’t wake up during the epilogue.And yet I find myself in the body of a fallen priest at the end of the novel, a tragic hero who had his mana circuit broken in the last war, being shunned, drown in debt, and destined to die not long after.Fortunately, I know just the cure.Unfortunately, the cure was in the hand of one of the Demon Lords—you know, the race that my kingdom just wage war with.Would he give me the cure if I asked him politely? There’s no harm in trying, right? I’d die if I didn’t get the cure, anyway.“Sure, but you have to be my bride as the price,” the Demon Lord said....huh? Sir, you know I’m (technically) a priest, right?

Wang Yi gets a key, opening a door in 2022 will lead to 1982, and opening a door in 1982 will return to 2022.

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.
