Child from the Dungeon - Chapter 4: Black Ones

In the second year of the apocalypse, Du Yue died alone, killed by apathy and exposure to extreme weather. Somehow, she opened her eyes to find herself not only alive, but also back when it was three months before the apocalypse. Despite the surprise, she thought about the upcoming disasters and upheavals. First, it was the fog that carried a virus that stayed for a month.

Then, global temperatures rose to over 120 degrees, evaporating most of the world’s water and melting all the icebergs. After that were level-10 earthquakes, cyclones, tsunamis, permanent eclipse, and avid rain… and that was not all, because after global warming, came global freezing. As temperatures dropped to below negative fifty, the savagery humans displayed was far worse than any imagined horrors like zombies! Knowing what was coming, Du Yue sold off her family property and used the pocket dimension her mother left her to hoard as many resources as possible, so that she could survive the apocalypse. Meat? Grain? Oil? Spices? Weather gear?

She bought everything! Steaks, French fries, spaghetti, and canned food must all be stocked up! To He Xing, the male lead, she was a god and the key to surviving the apocalypse!

Earth is dying. The sun is expanding at an uncontrollable rate, but Theo Spencer is alright with this. He's led a deplorable life. When the end comes, a mysterious entity grants him the gift of reincarnation. The gift of a quiet life as an alchemist.

Theo awakens in a small town in the southern reaches of a small kingdom in a non-human body. Broken Tusk doesn't seem like much, but his legendary alchemy skills will soon turn their fortune.

Join Theo on his journey to turn the swamp-town of Broken Tusk into a prosperous trade town.

As a top cultivator in the Canglang Realm, Fang Mu has been a little troubled recently.

Because his new apprentice seems to be a little brainless.

…

Brain-disabled apprentice: “Master, the GM you killed is dead!”

Fang Mu: “Nonsense, people are killed and still not dead?”

Brain-disabled apprentice: “No, I mean, he died in the real world!”

Fang Mu: “Isn’t this the reality?”

The brain-dead apprentice “Of course not, you are just an NPC in the game!!!”

Fang Mu: “…”

…

Brain-disabled apprentice: “By the way, master, the last time it was a closed beta test, how come you haven’t been recalled?”

Fang Mu: “Oh, there was indeed a time travel back in the first two months.

But here I was blocked. ”

Brain-disabled apprentice: “Master, you are a bug…”

“Um?”

“Master, you will be corrected by GM with code!”
