Legend of Great Tang’s Twin Dragons - Vol 53 Chapter 7: Mountain and River Exhausted

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.
I had no idea about what I have done.
On May 1st, Conan ‘the God of Death’ came to my house. I was forced to let him in and we get involved in a criminal case.
On May 8th, Bruce Wayne ‘Batman’ came to me. I was forced to follow him to fight crime.
On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.

The Empress does not grant my resignation.

Billions of Humans transmigrated to another dimension, each became a Land Ruler at the start and owned a castle. Each Land Ruler would draw a random starting Soldier-type Building, used to arm their castles. Recruit more soldier-types, plunder resources, and dominate the world! Some drew the Sacred Palace of Knights from the start and commanded troops of knights to crush all obstacles in its way, ruling over vast lands. Some drew the Goblin Cave, developed castle trade, and became renowned dirty profiteers. Of course, more people only drew the most unremarkable soldier-types: Goblins, Lizard Man, Skeleton Soldiers…… These people could only kneel before the powerful Land Rulers and serve them as slaves. But Mike was an exception. His starter soldier-type building was, Dragon Nest! Glacial Dragon, Hellfire Dragon, Undead Dragon, Black Dragon…... When one after another dragon egg appeared before Mike, he suddenly felt that…...conquering the World seemed quite manageable?

This story is set during the end of the Sui Dynasty, a time where multiple powers struggled for supremacy and power.

Into the fray enters two orphans Kou Zhong and Xu Ziling; these two youths by many chances and luck obtain ‘The Secret to Long Life’ allowing the two to obtain profound martial abilities and a chance to rise to the top in this age of turmoil.
