She was the head of a powerful, medicine-orientated aristocratic family.

Crossing through a millennium, she ended up in the body of the General Household’s “trash” young miss, whose engagement with the Crown Prince was just broken as she suffered under everybody’s taunts!

In the drafting feast, she was re-engaged by the Emperor to marry the famous disabled prince!

Everybody laughed, a blind trash with a disabled wastrel. What a perfect match!

However, they didn’t know that in her hand, she grasped the long-lost primordial pill recipes! Her practice in medicine had reached the apex! Her contracted beasts were unique in the world!

What was the most frightening, was the disabled prince she was engaged to…….

A black-belly full of dirty tricks, with a heaven-opposing cultivation physique, he defeats all geniuses!

In his wheelchair during the day, yet entangling her in bed as he trained his waist muscles… MF! Is he really crippled!?

Upon waking up, the whole people crossed the alien world.

This is a terrifying world, almost immeasurable.

There are dragons, griffins, goblins, goblins, dwarves, and orcs.

There are also zombies, undead dens, and various mythological monsters.

Everyone is a lord, starting with a life experience, a small courtyard, and three farmers.

To get rich, start by arranging trees and gradually establishing territory.

Lords need to explore the map, occupy areas, obtain resources, develop urban construction, and conquer monster dens.

Every other month, you need to resist the looting of monster legions and various alien forces in order to survive.

Zong Shen started the game and awakened the strategy system.

Raiders will appear in everything you can see.

Help him find all the hidden treasures.

[The crooked neck tree 50 meters southeast of the territory is actually not simple. 】

[Go forward 35 steps from your current position and start digging, you will get a surprise. 】

[Don’t look, this treasure chest is a trap, and the poison gas inside will make you unconscious for three days and three nights. 】

While others were still struggling to support, Zong Shen had already built a strong city.

With countless powerful soldiers and epic heroes, resources are piled up like a mountain.

Epic dragon Nithogg: “You…Don’t come here…I will give you all the treasures!”

Chief Goblin: “I am willing to serve the adults.”

King of Avalon: “I am willing to marry my beloved little daughter to you…”

Zong Shen: “Children make choices, I want them all!”
