Shen Yu's world is facing the apocalypse. With the help of his Gray Mist Space, he could do good things such as saving lives to gain more gray mist and use it to do everything he wants to do. And what's more, no one but him can survive in the Space. However, this time, two figures walk out of the Space, and when they spin around, Shen Yu is shocked, because the two figures are all him from different worlds.“Your world is facing an apocalypse too?”“Indeed.”

Yu Yi found herself transmigrated into a female protagonist in a xianxia novel, destined to suffer both physically and emotionally.The entire novel was 800,000 words long. For 700,000 words, she endured extreme torment. In the remaining 100,000 words, the heroine reconciled with her past, found true love without regrets, and achieved a happy ending with the male lead.Yu Yi absolutely refused to be this pitiful scapegoat.To avoid the main plot, she adhered to the basic principle of “where he is, I am not; where I am, he is not.” She laid low in her sect, dodging every opportunity to encounter the male lead.Five years passed, and she finally severed this ill-fated connection.The male lead married someone else. Yu Yi let out three wild laughs as she stepped out of the sect gates, happily rushing towards the colorful world outside.However, she didn’t expect that in her excessive joy, she would accidentally stumble upon the mu*der scene of the main villain.Yu Yi hid in the bushes, watching Xue Chenjing, dressed in white robes now stained with blood, slowly crushing someone’s skull. She was so terrified she didn’t dare to breathe.In the dead silence, a noisy voice suddenly rang out: [Master, look quick! It’s your wife! Your wife has finally come online. Isn’t she adorable, curled up and hiding in the bushes like that?]Yu Yi was shocked: Surely it can’t be referring to me?[She’s even wearing a red dress, matching couple outfits with you.]Yu Yi clutched her pomegranate-red skirt tightly, glancing at the hem of Xue Chenjing’s robe. What couple outfit? Isn’t that just stained red with blood?Xue Chenjing flicked the blood from his fingertips, his gaze sweeping towards the bushes. He asked in bewilderment, “Whose wife?”The system pulled out a masterpiece of literature, tapping the cover and asserting confidently: [Your wife.]

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!!!
