In the third year of the Republic of China, Yao Zhi was 14 years old and the jewel of the governor’s office.

At that time, the young man next to the marshal’s mansion was still physically disabled and had his feet deep in the mud. Yao Zhi stretched out her hand and tried to help him, but the boy, who looked fierce, shut his eyes and was heartless. Yao Zhi has been the white moonlight of all young men in Beijing since childhood. Her crescent eyes were curved, and her beauty was incomparable.

Shen Xu regarded her as a god in his heart and never dared to put her in the bottom of his heart.

He looked up at the gods on a bright moonlit night, never thinking that one day she would take the initiative and rush into his chest. Yao Zhi, who became the pinnacle of his two lives, grabbed his clothes and said quietly.

“Shen Xu, if you ignore me again, I’ll kiss someone else.” Shen Xu couldn’t suppress his youthful emotions. He held the god’s waist tightly. He had no choice but to beg her repeatedly. “Zhizhi… “

“Don’t leave me,” she said, knowing that he was young and humble and that he had feelings as deep as the sea for her.

She wouldn’t leave. She would be the apex of the young man’s heart and stay together with him.

- Description from Novelupdates

All humans transmigrated to a parallel world, where every one of them was a king with the territory.

They participated in a game called The Ranking of Kings and fought to become the best nation.

The rankings were determined based on various aspects such as military, technology, commerce, culture, and religion.

In the game, the kings would awaken different attributes of the land.

Someone exclaimed, “My Renewable Resources attribute allows me to enhance raw materials such as timber and minerals. I want to build the strongest empire of commerce!”

Another king challenged, “My King of the Undead attribute allows me to summon dead souls to fight for me. Who dares to stand in the way of my troops of one million undead?”

The third king declared, “My Integrated Production attribute will ensure that technology is being implemented efficiently. You foolish barbarians, watch as my nation advances a few centuries ahead of yours.”

The fourth king said, “My Miracle Summon attribute can increase the efficiency of evangelism by 1000%. I look forward to the day when my nation becomes the top religion in the world.”

…

Li Xiang revealed a pondering look as he looked at his attributes shown on the virtual data panel.

[Attribute 1: Devils’ Den (SSS rank, unique)]

[You acquired the original birthplace of the Dragon Clan. All the legendary dragons are now under your command.]

[Attribute 2: Devouring Lands (currently A rank, evolvable)]

[When you annex the territory of other kings, you seize their attributes as well. Furthermore, you can level up these attributes to even higher ranks.]
