Traveling Between Two Tang Dynasties: Li and I Become Sworn Brothers

Xu Yi acquired a portal that let him travel back and forth between the modern world and ancient dynasties, and from then on, he rose to the top.

His very first customers were Li Er and Fang Xuanling. After a long conversation, he somehow even became sworn brothers with Li Er.

Old Li: "These potatoes really are immortal treasures. They yield thirty dan per mu!"

Old Li: "Little brother, this electric scooter is incredibly fast. It even beats my prized Ferghana horse!"

Old Li: "This stuff really boosts virility? You aren't pulling my leg, are you...?"

In return, Li Er also gave Xu Yi a few little gifts.

When Xu Yi brought those gifts back to the modern world, the whole world was stunned.

Expert: "Holy crap, the Roman pope's scepter!"

Professor: "Holy crap, isn't this painting an authentic work from the early Tang?"

From then on, Xu Yi became rich and powerful in modern society.

Until one day, Xu Yi gave Li Er a globe and a few small weapons...

Beneath the heavens, the dragon banners of Great Tang fly everywhere!
