[Hello everyone, my name is Amamiya Ren. This might seem like an abrupt self-introduction, and honestly, I think so too.][In fact, when I first heard my own name, I had a bad premonition. Fortunately, I didn’t encounter Shido Masayoshi or Akechi Goro.][But when I discovered that the high school I was going to attend was called Teitan High School, I knew I was in trouble.][I thought I had successfully avoided the traitor, but I didn’t expect that I couldn’t escape the god of death either.][Then, as I dug deeper, I found out more information that made my heart race.][I learned about Shinomiya, who is as renowned as the Suzuki family, and Sanzenin, which surpasses both Suzuki and Shinomiya.][But none of that is the main point.

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 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.]
