I traveled through the Cretaceous period and farmed with the ever-changing dog egg.

Hearing the system's words, Lin Chaoyan was terrified and said a heartfelt goodbye to Tie Zui.

"Thank you! Thank you so much! Besides my parents, you're the only one I have. I don't know what you'll be like next time, but as long as it's you, that's enough..."

At the last moment, she flashed back into her spatial dimension. Through continuous hunting of groundhogs over the past year, Lin Chaoyan had already stockpiled tens of thousands of kilograms of dried meat. She had also harvested two crops of wheat and rice, so she had no shortage of food.

The Cretaceous-Paleogene extinction event was the fifth mass extinction on Earth, wiping out approximately 75% to 80% of all life on the planet. This extinction event most significantly impacted the dinosaurs, who had ruled the Earth for 1.6 million years, bringing them to the brink of extinction.

On this bright, sunny day, a huge, comet-like object streaked rapidly across the sky from afar, growing brighter as it drew nearer, until it was even brighter than the sun. Lin Chaoyan watched in disbelief as it disappeared below the horizon, followed by a dazzling flash of light where the comet had vanished.

Before she could react, the earth began to shake violently, and everything outside became chaotic. Birds and beasts scattered and fled, swallowed by the earth, struggling. This process lasted for a long time.

When Lin Chaoyan recovered from the earthquake, she was lucky that Tiezui hadn't received any notification that it was dead. Then she witnessed something even more terrifying.

A colossal wave, as high as a mountain thousands of meters tall, appeared in her vision and crashed towards the creatures. At this moment, many animals would recover from their surprise and begin to instinctively run in the opposite direction. However, all of this was in vain, as the giant wave mercilessly swallowed them up.

[Host, Iron Mouth is dead! He hasn't been resurrected yet.]

Did you think that was the end of it? Not at all. Lin Chaoyan witnessed countless meteor showers appear in the sky after the tsunami finally stopped. These were not romantic meteor showers, but rather bomb-like lava fireballs and lava rain falling rapidly.

The sky turned fiery red as lava and fire swept across the globe, and survivors began another great escape. Lin Chaoyan listened to the deafening roar and watched as the creatures were engulfed and scorched by the molten lava; she could almost smell the roasting meat. At that moment, the entire world had become a living hell.

"It should end soon!" Lin Chaoyan prayed silently. But fate is cruel, and things don't always go as planned. This process lasted a very long time, so long that Lin Chaoyan stopped paying attention to the disaster. If it weren't for the existence of relevant data and systems, she wouldn't even remember which year the fire was extinguished.

Lin Chaoyan only knew that one morning when she woke up, she found the sky was gray, the entire sky was covered by a layer of gray that never seemed to dissipate, and the sun had disappeared. Lin Chaoyan's sense of time gradually began to collapse, because there was no longer any distinction between day and night outside, the temperature began to drop sharply, and it began to snow heavily, unlike anything that had ever happened outside the poles during the Cretaceous period.

(Note: The average temperature during the Cretaceous period was 4 degrees Celsius higher than it is now.) Without the sun, the Earth's ecosystem's only energy source was completely cut off, and the ecosystem began to collapse.

Without an iron tongue, she single-handedly lived a life of working from sunrise to sunset within the space. During this time, aside from chatting with the system to understand current events, she focused on cultivation and farming. She never allowed herself a moment's rest. She made pickled green beans, pickled various vegetables, dried radishes, dried sweet potatoes, dried vegetables…

Warring States Period

"Hoeing the rice at noon, sweat drips onto the soil. Who knows that every grain in the bowl is the result of hard work?" Lin Chaoyan looked at the rice paddies where the rice seedlings had just been planted and had vowed countless times in her heart not to be picky about food and not to waste food.

"What era is this?" How long have I been farming? It feels like time has stood still in the mountains. Lin Chaoyan had absolutely no idea what year it was.

[During the Warring States period, your current location is the Yinshan Mountains near the State of Zhao. Congratulations, Yan Yan, you're about to meet your crush!]

Yinshan Mountain is the northernmost border of the Han Chinese people. It is located north of Hohhot in present-day Inner Mongolia. During the Warring States period, the Great Wall of the Zhao State was built along the Yinshan Mountain range.

Yinshan and Helan Mountain were the traditional northern border of the Han Chinese: "We will not let the barbarian horses cross Yinshan" was a defensive phrase; "We will drive long chariots to break through the Helan Mountain pass".

The Warring States period? She murmured to herself before realizing, "The Warring States period? Doesn't that mean I can meet Zheng Ge, Fusu, Han Fei, Guiguzi, and the others?"

"Hahaha!!! I'm finally invincible and can go out and have some fun!" He thought of the cultivation manual, magical artifact, and robes he had drawn. He had never had a chance to wear them out and show off, but now he finally had the opportunity.

"Woo woo woo!" Dog Egg is now a white deer. He has been a human before, a man, a woman, an old person, and a child. Each time, he would choose a nearby corpse, so only corpses with people nearby would become human.

"Alright, alright! I'll take you with me. We'll try to get you an awesome body on the battlefield in a while." Corpses are all there for you to choose from, hehe!! Cough cough!! Lin Chaoyan, you should at least be more mature after living for tens of millions of years. That laugh is too lewd.

"Woof woof woof~~" Dog Egg barked happily, it sounded incredibly nice, crisp and melodious, like pearls gliding through the air, a pure and white sound that seemed to travel through the mountains and forests.

She ran quickly, carrying her shoes, and drew water from the well to wash herself. Then she went to the vegetable garden, picked two cucumbers, washed them, and the two of them, one human and one deer, began to eat the cucumbers.

"It's all-natural and homegrown, a hundred times tastier than vegetables from modern greenhouses. Don't you agree, Gou Dan!"

"Yo-yo~" Gou Dan barked twice and ate the cucumber tail in her hand.

"The Yinshan Mountains, as a natural barrier, have been a strategic location fought over by military strategists since ancient times. For a considerable period of history, the Yinshan Mountains were the front line that the Central Plains agricultural people and the Mongolian Plateau nomadic people fought fiercely for.

General Li Guang, known as the Flying General, guarded the northern gate of the Han Dynasty here, sniping at the Xiongnu.

The war god Huo Qubing embarked on his journey to seal the wolf's lair here.

Li Jing and Zhang Gongjin led 3000 Tang soldiers here, shattering the Eastern Turkic Khaganate and reducing it to ashes.

"I've unintentionally chosen a great place. Even if I just stay here, I can witness countless pivotal historical events." Lin Chaoyan was excited just thinking about it. She had been lonely for too long and longed to go out into the world. She couldn't wait to plunge into a crowd of people.

【Yan Yan, with your current strength, as long as you don't interfere with history, you can go wherever you want without making yourself suffer. If anyone makes you suffer in the future, just beat them up.】 Now, even if the Time and Space Administration finds out, they'll have to think twice.

"Interfering with history? Brother Zheng! I really didn't want him to die so young, but he was only three years older than Liu Bang and died so young. What a pity! If there were an elixir of immortality, I'd give it all to him. Let him live, let him live as long as he wants." My charming ancestor just wanted an elixir of immortality, didn't he? Why can't I grant his wish?

That damned swindler Xu Fu tricked my brother Zheng into taking poison, cheated people out of money, and then fled overseas to establish himself as king.

【It's not impossible! As long as he's willing to sacrifice! However, he can't possibly do it. Not only him, but all emperors, knowing the cost, couldn't do it.】 There's always a trade-off, Yan Yan, your naivety is due for you to experience some things.

Lin Chaoyan was overjoyed like a fool upon hearing that Zheng Ge had a chance at immortality. What a waste of that cool, beautiful face! Such a lovely woman, and she just had to have a mouth. "The price? What price? I'll pay!"

"...You can't give him that. There's always a trade-off. As long as Ying Zheng (Qin Shi Huang) dies, he'll achieve immortality. You can't help him with that."

"What? How can someone who's dead achieve immortality? Immortality that means being remembered in history?"

How can you live forever after you die? Become a ghost? If you can't, then you can't. Why are you messing with me? Lin Chaoyan turned around and went inside to prepare dinner, deciding to ignore him.

[There are gains and losses! Ying Zheng must die according to the historical timeline.] Lin Qi'an tried to get her to open Pandora's box.

"Ah, right, right, right!!" Completely confused, just trying to make a living! Never mind, making a living is the most important thing.

【Yan Yan, it's time to harvest the wheat and other grains. In this era, there are no peanuts, corn, chili peppers… We shouldn't grow these grains in the outside world.】
