[Simulation] + [Isekai] + [Goblin] + [Harem]After a long sleep, I awakened in a new life—as a goblin. Weak and insignificant, I found myself reborn as the lowest creature in a world filled with hostility and danger. But from the shadows of this cruel world, a silent rise begins...

Lu Liran, the former deputy captain of the first federal mobile team, disappeared in a great war, and his life and death are unknown.
Seriously injured in the war, lingering on his last breath and penniless, Lu Liran was luckily bound by the survival system.
Under the tasks issued by the system——

The Giant at thirty degrees below zero, conquer the Arlok Glacier;
In the No Man’s land under the black wind and sand, travel deep into the oasis in the hinterland of Salba Desert;
The Island in the Sky under the blue sky, the challenge of surviving on an uninhabited island;
The Blue Hole in the Endless Abyss, exploring deep sea wrecks and lost ancient cities.
The Muddy Lands, the Forest of White Bones, gathering specialties of the Haunted Swamp;
The Lord of Fire, the giant dragon lurking on the ground……

Therefore, in the Desolate Star that hates the federal army the most, a man with a disfigured face and mysterious identity quietly appeared in the top ten dangerous uninhabited regions of Desolate Star. In exchange for rich bounty rewards by hunting rare and exotic beasts that ordinary people can’t hunt, and the live broadcast of wilderness survival, he also started rapidly sweeping the entire planet.

“Ah, the anchor looks so scary, no one dares to marry such an Alpha no matter how powerful he is!”

“??? Brother Lu, I can! Marry me! The sense of security is at max level, like!”

“The anchor is really a god. This is the first time I’ve seen someone at the top of this year’s list of Desolate Star’s Most Attractive Alpha + Least Wanted to Marry Alpha at the same time…”

During a live broadcast, a heavy rain washed away the scar on Lu Liran’s face.

The whole live room is boiling!!!

“Marry me, marry me! Brother, marry me!”

After the live broadcast was closed, another man, so handsome that people subconsciously held their breath, appeared. He surrounded Lu Liran’s body and whispered: “You’ve been missing for so many years with my cub, when are you going to give me a name?”

Lu Liran: “…”

Yes, this is still an old-fashioned story of O pretending to be A and running away with joy.

…

His Excellency, the First Commander of the Federal Army, disappeared suddenly in the peaceful post-war era. Until one day, everyone noticed that he appeared in a live broadcast room, happily pretending to be a s*upid human-shaped pendant, and unscrupulously pestering a male anchor with a terrifying face.

“Official announcement, this is the commander’s wife.” His Excellency, the Commander-in-Chief of the Federation, said so.

The live broadcast room is boiling again!!!
